I mean, you watch the big President, the big leader, give a speech on television — the television could be monitoring you and knowing whether you're angry or not just by analyzing the cues.” MacDonald Brainwashed (Tom words of wisdom) – The Rap   Eating almonds daily boosts exercise recovery molecule by 69% among ‘weekend warriors' Appalachian State University, January 6, 2023 For those who exercise regularly, eating almonds each day might be the ideal new year's resolution. A randomized controlled trial in Frontiers in Nutrition showed that female and male participants who ate 57g almonds daily for one month had more of the beneficial fat 12,13-dihydroxy-9Z-octadecenoic acid (12,13-DiHOME) in their blood immediately after a session of intense exercise than control participants. This molecule, a so-called oxylipin (oxidized fat) is synthetized from linoleic acid by brown fat tissue, and has a beneficial effect on metabolic health and energy regulation. Corresponding author Dr. David C Nieman, a professor and director of the Appalachian State University Human Performance Laboratory at the North Carolina Research Campus, said, “Here we show that volunteers who consumed 57g of almonds daily for one month before a single ‘weekend warrior' exercise bout had more beneficial 12,13-DiHOME in their blood immediately after exercising than control volunteers. They also reported feeling less fatigue and tension, better leg-back strength, and decreased muscle damage after exercise than control volunteers.” The clinical trial involved 38 men and 26 women between the ages of 30 and 65, who didn't engage in regular weight training. Approximately half were randomized to the almond diet group, and the other half to the control group, who daily ate a calorie-matched cereal bar. The researchers took blood and urine samples before and after the four-week period of dietary supplementation. Performance measures included a 30 second Wingate anaerobic test, a 50 meter shuttle run test, and vertical jump, bench press, and leg-back strength exercises. Additional blood and urine samples were taken immediately after this 90 minute session of ‘eccentric exercise' and daily for four days afterwards.  As expected, the 90 minute exercise led to an increase in the volunteers' self-reported feeling of muscle damage and muscle soreness, as well as an increased POMS score, indicating self-reported decreased vigor and increased fatigue, anxiety, and depression. The exercise also resulted in transient elevated levels of pro-inflammatory cytokines such as IL-6, IL-8, IL-10, and MCP-1 in the blood, consistent with minor muscle damage. However, these changes in cytokines were equal in the almond and cereal bar groups. Importantly, immediately after exercise, the concentration of the beneficial 12,13-DiHOME was 69% higher in blood plasma of participants in the almond group than in participants in the control group. 12,13-DiHOME is known to increase the transport of fatty acid and its uptake by skeletal muscle, with the overall effect of stimulating metabolic recovery after exercise. The reverse pattern was found for another oxylipin, the mildly toxic 9,10-Dihydroxy-12-octadecenoic acid (9,10-diHOME), which was 40% higher immediately after exercise in the blood of the control group than in the almond group. Unlike 12,13-DiHOME, 9,10-diHOME has been shown have negative effects on overall health and the body's recovery to exercise. Nieman and colleagues concluded that daily consumption of almonds leads to a change in metabolism, downregulating inflammation and oxidative stress from exercise and enabling the body to recover faster. “We conclude that almonds provide a unique and complex nutrient and polyphenol mixture that may support metabolic recovery from stressful levels of exercise. Almonds have high amounts of protein, healthy types of fats, vitamin E, minerals, and fiber. And the brown skin of almonds contains polyphenols that end up in the large intestine and help control inflammation and oxidative stress,” said Nieman. Omega-3 supplements can prevent childhood asthma Copenhagen University Hospital, December 29, 2022 Taking certain omega-3 fatty acid supplements during pregnancy can reduce the risk of childhood asthma by almost one third, according to a new study from the Copenhagen Prospective Studies on Asthma in Childhood (COPSAC) and the University of Waterloo. The study, published in the New England Journal of Medicine, found that women who were prescribed 2.4 grams of long-chain omega-3 supplements during the third trimester of pregnancy reduced their children's risk of asthma by 31 per cent. Long-chain omega-3 fatty acids, which include eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are found in cold water fish, and key to regulating human immune response. “We've long suspected there was a link between the anti-inflammatory properties of long-chain omega-3 fats, the low intakes of omega-3 in Western diets and the rising rates of childhood asthma,” said Professor Hans Bisgaard of COPSAC at the Copenhagen University Hospital. “This study proves that they are definitively and significantly related.” The testing also revealed that women with low blood levels of EPA and DHA at the beginning of the study benefitted the most from the supplements. For these women, it reduced their children's relative risk of developing asthma by 54 per cent. “The proportion of women with low EPA and DHA in their blood is even higher in Canada and the United States as compared with Denmark. So we would expect an even greater reduction in risk among North American populations,” said Professor Stark. “Identifying these women and providing them with supplements should be considered a front-line defense to reduce and prevent childhood asthma.” “Asthma and wheezing disorders have more than doubled in Western countries in recent decades,” said Professor Bisgaard. “We now have a preventative measure to help bring those numbers down.” Currently, one out of five young children suffer from asthma or a related disorder before school age. Study shows gardening may help reduce cancer risk, boost mental health University of Colorado at Boulder, January 6, 2023 The first-ever, randomized, controlled trial of community gardening found that those who started gardening ate more fiber and got more physical activity—two known ways to reduce risk of cancer and chronic diseases. They also saw their levels of stress and anxiety significantly decrease. The findings were published in The Lancet Planetary Health. “These findings provide concrete evidence that community gardening could play an important role in preventing cancer, chronic diseases and mental health disorders,” said senior author Jill Litt, a professor in the Department of Environmental Studies at CU Boulder. “No matter where you go, people say there's just something about gardening that makes them feel better,” said Litt, who is also a researcher with the Barcelona Institute for Global Health. Some small observational studies have found that people who garden tend to eat more fruits and vegetables and have a healthier weight. But it has been unclear whether healthier people just tend to garden, or gardening influences health. Only three studies have applied the gold standard of scientific research, the randomized controlled trial, to the pastime. None have looked specifically at community gardening. To fill the gap, Litt recruited 291 non-gardening adults, average age of 41, from the Denver area. More than a third were Hispanic and more than half came from low-income households. The gardening group received a free community garden plot, some seeds and seedlings, and an introductory gardening course through the nonprofit Denver Urban Gardens program and a study partner. By fall, those in the gardening group were eating, on average, 1.4 grams more fiber per day than the control group—an increase of about 7%. The authors note that fiber exerts a profound effect on inflammatory and immune responses, influencing everything from how we metabolize food to how healthy our gut microbiome is to how susceptible we are to diabetes and certain cancers. While doctors recommend about 25 to 38 grams of fiber per day, the average adult consumes less than 16 grams. “An increase of one gram of fiber can have large, positive effects on health,” said co-author James Hebert, director of University of South Carolina's cancer prevention and control program. The gardening group also increased their physical activity levels by about 42 minutes per week. Public health agencies recommend at least 150 minutes of physical activity per week, a recommendation only a quarter of the U.S. population meets. With just two to three visits to the community garden weekly, participants met 28% of that requirement. Study participants also saw their stress and anxiety levels decrease, with those who came into the study most stressed and anxious seeing the greatest reduction in mental health issues. The study also confirmed that even novice gardeners can reap measurable health benefits of the pastime in their first season. As they have more experience and enjoy greater yields, Litt suspects such benefits will increase. Researchers shed light on how exercise preserves physical fitness during aging Joslin Diabetes Center, December 6, 2023 Proven to protect against a wide array of diseases, exercise may be the most powerful anti-aging intervention known to science. However, while physical activity can improve health during aging, its beneficial effects inevitably decline. The cellular mechanisms underlying the relationship among exercise, fitness and aging remain poorly understood.   In a paper published in the Proceedings of the National Academy of Sciences, researchers at Joslin Diabetes Center investigated the role of one cellular mechanism in improving physical fitness by exercise training and identified one anti-aging intervention that delayed the declines that occur with aging in the model organism. Together, the scientists' findings open the door to new strategies for promoting muscle function during aging.   “Our data identify an essential mediator of exercise responsiveness and an entry point for interventions to maintain muscle function during aging.”  That essential mediator is the cycle of fragmentation and repair of the mitochondria, the specialized structures, or organelles, inside every cell responsible for producing energy. Mitochondrial function is critical to health, and disruption of mitochondrial dynamics  the cycle of repairing dysfunctional mitochondria and restoring the connectivity among the energy-producing organelles — has been linked to the development and progression of chronic, age-related diseases, such as heart disease and type 2 diabetes.   “As we perceive that our muscles undergo a pattern of fatigue and restoration after an exercise session, they are undergoing this mitochondrial dynamic cycle,” said Blackwell, who is also acting section head of Immunobiology at Joslin. “In this process, muscles manage the aftermath of the metabolic demand of exercise and restore their functional capability.”  “We determined that a single exercise session induces a cycle of fatigue and physical fitness recovery that is paralleled by a cycle of the mitochondrial network rebuilding,” said first author Juliane Cruz Campos, a postdoctoral fellow at Joslin Diabetes Center. “Aging dampened the extent to which this occurred and induced a parallel decline in physical fitness. That suggested that mitochondrial dynamics might be important for maintaining physical fitness and possibly for physical fitness to be enhanced by a bout of exercise.”   Finally, the researchers tested known, lifespan-extending interventions for their ability to improve exercise capacity during aging. Worms with increased AMPK — a molecule that is a key regulator of energy during exercise which also promotes remodeling of mitochondrial morphology and metabolism — exhibited improved physical fitness. They also demonstrated maintenance of, but not enhancement of, exercise performance during aging. Worms engineered to lack AMPK exhibited reduced physical fitness during aging as well as impairment of the recovery cycle. They also did not receive the age-delaying benefits of exercise over the course of the lifespan.   Nighttime electronic device use lowers melatonin levels Brigham and Women's Hospital, December 24 2022.  The Proceedings of the National Academy of Science published the findings researchers at Boston's Brigham and Women's Hospital of a suppressive effect for evening use of light-emitting electronic devices on sleep and melatonin secretion. “Electronic devices emit light that is short-wavelength-enriched light, which has a higher concentration of blue light — with a peak around 450 nm — than natural light,” explained lead author Anne-Marie Chang. “This is different from natural light in composition, having a greater impact on sleep and circadian rhythms.”  Twelve healthy adults were randomized to read a light-emitting eBook or a printed book in dim room light approximately four hours before bedtime for five evenings. At the end of the five day period, participants switched their assignments. Blood samples collected during portions of the study were analyzed for melatonin levels.  Sleep latency, time and efficiency were assessed via polysomnography.  eBook reading was associated with more time needed to fall asleep and less rapid eye movement sleep in comparison with reading a printed book. Evening melatonin levels were suppressed by an average of 55.12% in eBook readers, while those who read printed books had no suppression. Compared to printed book reading, the onset of melatonin release in response to dim light occurred 1 ½ hours later the day following reading of an eBook. “Our most surprising finding was that individuals using the e-reader would be more tired and take longer to become alert the next morning,” Dr Chang reported. “This has real consequences for daytime functioning, and these effects might be worse in the real world as opposed to the controlled environment we used.”  “We live in a sleep-restricted society, in general,” she added. “It is important to further study the effects of using light-emitting devices, especially before bed, as they may have longer term health consequences than we previously considered.” Iron deficiency anemia associated with hearing loss Penn State University, December 29, 2022 In a study published online by JAMA Otolaryngology-Head & Neck Surgery, Kathleen M. Schieffer, B.S., of the Pennsylvania State University College of Medicine, Hershey, Pa., and colleagues examined the association between sensorineural hearing loss and conductive hearing loss and iron deficiency anemia in adults ages 21 to 90 years in the United States. Approximately 15 percent of adults report difficulty with hearing. Because iron deficiency anemia (IDA) is a common and easily correctable condition, further understanding of the association between IDA and all types of hearing loss may help to open new possibilities for early identification and appropriate treatment. For this study, using data obtained from deidentified electronic medical records from the Penn State Milton S. Hershey Medical Center in Hershey, Pa., iron deficiency anemia was determined by low hemoglobin and ferritin levels for age and sex in 305,339 adults ages 21 to 90 years; associations between hearing loss and IDA were evaluated. Of the patients in the study population, 43 percent were men; average age was 50 years. There was a 1.6 percent prevalence of combined hearing loss (defined as any combination of conductive hearing loss [hearing loss due to problems with the bones of the middle ear], sensorineural hearing loss, deafness, and unspecified hearing loss) and 0.7 percent prevalence of IDA. Both sensorineural hearing loss (SNHL; when there is damage to the cochlea or to the nerve pathways from the inner ear to the brain) (present in 1.1 percent of individuals with IDA) and combined hearing loss (present in 3.4 percent) were significantly associated with IDA. Analysis confirmed increased odds of SNHL and combined hearing loss among adults with IDA. “An association exists between IDA in adults and hearing loss. The next steps are to better understand this correlation and whether promptly diagnosing and treating IDA may positively affect the overall health status of adults with hearing loss,” the authors write.

FACT CHECK: it did not go well for 2022 Fauci.  (1:23) Sam Bailey & Jessic Rose Part 1 (22:33) Gary Null Speaking Out at the NYS Assembly Hearing  (25:00)   Higher omega-3 levels linked to better sleep University of British Columbia, September 14 2022.  Having higher blood concentrations of the omega-3 polyunsaturated fatty acids eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA) was found to be associated with a reduction in excessive sleep in an analysis reported in 2022 in the American Journal of Clinical Nutrition. Sleep duration of over 9 hours per night has been correlated with an increased risk of cardiovascular disease and premature mortality from all causes. The analysis included 21,653 participants in 12 studies for whom information was available concerning sleep duration and/or difficulty falling asleep and blood levels of the omega-3 fatty acids EPA, DHA, ALA and, when available, DPA, and the omega-6 fatty acids AA and LA. When men and women whose fatty acid levels were among the lowest 20% of participants were compared to those whose levels were among the top 20%, individuals whose DHA intake was highest had a 22% lower risk of excessive sleep. Being among those who had the highest intake of EPA plus DHA and DPA was associated with a 24% lower risk. The authors noted that DHA's role in regulating melatonin production helps regulate sleep.  Twice-daily nasal irrigation reduces COVID-related illness, death Medical College of Georgia at Augusta University, September 13, 2022 Starting twice daily flushing of the mucus-lined nasal cavity with a mild saline solution soon after testing positive for COVID-19 can significantly reduce hospitalization and death, investigators report. They say the technique that can be used at home by mixing a half teaspoon each of salt and baking soda in a cup of boiled or distilled water then putting it into a sinus rinse bottle is a safe, effective and inexpensive way to reduce the risk of severe illness and death from coronavirus infection that could have a vital public health impact.  “By giving extra hydration to your sinuses, it makes them function better. “We found an 8.5-fold reduction in hospitalizations and no fatalities compared to our controls,” says senior author Dr. Richard Schwartz, chair of the MCG Department of Emergency Medicine. “Both of those are pretty significant endpoints.” The study appears to be the largest, prospective clinical trial of its kind and the older, high-risk population they studied—many of whom had preexisting conditions like obesity and hypertension—may benefit most from the easy, inexpensive practice, the investigators say. They found that less than 1.3% of the 79 study subjects age 55 and older who enrolled within 24-hours of testing positive for COVID-19 between Sept. 24 and Dec. 21, 2020, experienced hospitalization. No one died.  Researchers know that the more virus that was present in your body, the worse the impact. “One of our thoughts was: If we can rinse out some of the virus within 24 hours of them testing positive, then maybe we can lower the severity of that whole trajectory,” she says, including reducing the likelihood the virus could get into the lungs, where it was doing permanent, often lethal damage to many. Baxter says the nasal irrigation with saline helps decrease the usual robust attachment. Saline appears to inhibit the virus' ability to essentially make two cuts in itself, called furin cleavage, so it can better fit into an ACE2 receptor once it spots one. Participants self-administered nasal irrigation using either povidone-iodine, that brown antiseptic that gets painted on your body before surgery, or sodium bicarbonate, or baking soda, which is often used as a cleanser, mixed with water that had the same salt concentration normally found in the body. Those who completed nasal irrigation twice daily reported quicker resolution of symptoms regardless of which of two common antiseptics they were adding to the saline water. Eating more spicy foods decreases your risk of early death by 14% Chinese Academy of Medical Sciences, September 7, 2022 According to an international team of researchers led by the Chinese Academy of Medical Sciences, eating spicy foods may be the key to longevity. They found that eating such foods on a regular basis can help prevent people from dying prematurely by 14 percent. While a variety of spicy foods are excellent, one in particular caught their attention. It was noted that consumption of fresh chili pepper, compared to other spicy foods, was most effective in providing people with a lower risk of dying from cancer, ischemic heart disease and diabetes. It's explained that fresh chili pepper's combination of powerful ingredients are responsible for such health-boosting benefits.(1) “Compared with non-fresh spicy foods such as dried chilli pepper, chilli sauce or chilli oil,” says Lu Qi, associate professor at Harvard School of Public Health, “fresh chilli pepper is richer in bioactive ingredients, including capsaicin, vitamin C, and other nutrients such as vitamin A, K, and B6 and potassium.”(1) To conduct the study, the experts from the Chinese Academy of Medical Sciences assessed nearly 490,000 participants. After a follow-up that averaged approximately seven years, 20,224 deaths were noted. Analysis of these people led to the finding that compared to those who ingested spicy foods less than once weekly, people who ate such foods one or two days per week had a 10 percent reduced risk of death. More impressive however, was the discovery that those who enjoyed spicy foods nearly every other day were at a 14 percent lowered risk of death compared to those who ate them less than once a week. In this large prospective study, we observed an inverse association between consumption of spicy foods and total mortality, after adjusting for potential confounders. Compared with those who ate spicy foods less than once a week, those who consumed spicy foods almost every day had a 14% lower risk of death. Inverse associations were also observed for deaths due to cancer, ischemic heart diseases, and respiratory diseases. The associations were consistent in men and women. Meditation holds the potential to help treat children suffering from traumas, difficult diagnoses or other stressors Wayne State University, September 13, 2022 Children actively meditating experience lower activity in parts of the brain involved in rumination, mind-wandering and depression, our team found in the first brain-imaging study of young people under 18 years old. Over-activity in this collection of brain regions, known as the default mode network, is thought to be involved in the generation of negative self-directed thoughts – such as “I am such a failure” – that are prominent in mental disorders like depression. In our study, we compared a simple form of distraction – counting backward from 10 – with two relatively simple forms of meditation: focused attention to the breath and mindful acceptance. Children in an MRI scanner had to use these techniques while watching distress-inducing video clips, such as a child receiving an injection. We found that meditation techniques were more effective than distraction at quelling activity in that brain network. This reinforces research from our lab and others showing that meditation techniques and martial arts-based meditation programs are effective for reducing pain and stress in children with cancer or other chronic illnesses – and in their siblings – as well as in schoolchildren during the COVID-19 pandemic. Researchers know a lot about what is happening in the brain and body in adults while they meditate, but comparable data for children has been lacking. Understanding what is happening in children's brains when they meditate is important because the developing brain is wired differently from the adult brain.  Pace as important as 10,000 steps for health, finds new research University of Sydney and University of South Denmark, September 13, 2022 Two studies, published in JAMA Internal Medicine and JAMA Neurology, monitored 78,500 adults with wearable trackers—making these the largest studies to objectively track step count in relation to health outcomes. The researchers from the University of Sydney, Australia and University of Southern Denmark found lowered risk of dementia, heart disease, cancer and death are associated with achieving 10,000 steps a day. However, a faster stepping pace like a power walk showed benefits above and beyond the number of steps achieved. “The take-home message here is that for protective health benefits people could not only ideally aim for 10,000 steps a day but also aim to walk faster,” said co-lead author Dr. Matthew Ahmadi, Research Fellow at the University of Sydney's Charles Perkins Centre and Faculty of Medicine and Health. Key points: Every 2,000 steps lowered risk of premature death incrementally by 8 to 11 percent, up to approximately 10,000 steps a day. Similar associations were seen for cardiovascular disease and cancer incidence. A higher number of steps per day was associated with a lower risk of all-cause dementia 9,800 steps was the optimal dose linked to lower risk of dementia by 50 percent, however risk was reduced by 25 percent at as low as 3,800 steps a day Feed a virus, starve a bacterial infection? Yale University, September 8, 2022 A new study puts some old folk wisdom to “feed a cold and starve a fever” to the test. In mouse models of disease, Yale researchers looked at the effects of providing nutrients during infection and found opposing effects depending on whether the infections were bacterial or viral.  Mice with bacterial infections that were fed died, while those with viral infections who were fed lived. “We were surprised at how profound the effects of feeding were, both positive and negative,” says senior author Ruslan Medzhitov, David W. Wallace Professor of Immunobiology and a Howard Hughes Medical Institute investigator at Yale School of Medicine. In the first series of experiments, the investigators infected mice with the bacterium Listeria monocytogenes, which commonly causes food poisoning. The mice stopped eating, and they eventually recovered. But when the mice were force fed, they died. The researchers then broke the food down by component and found fatal reactions when the mice were given glucose, but not when they were fed proteins or fats. When the researchers did similar studies in mice with viral infections, they found the opposite effect. Mice infected with the flu virus A/WSN/33 survived when they were force fed glucose, but died when they were denied food or given 2-DG.

NEWS: Sugar-studded protein is key to an Alzheimer's cure | The Brighter Side (01:38) In a bit of “reverse engineering” research using brain tissues from five people who died with Alzheimer's disease, Johns Hopkins Medicine researchers say they discovered that a special sugar molecule could play a key role in the development of Alzheimer's disease. This could indicate the molecule, known as a glycan, to be used as an early diagnostic test. And opens a way to perhaps prevention of the disease Cleaning up the disease-causing forms of amyloid and tau is the job of the brain's immune cells, called microglia. Earlier studies found that when cleanup is impaired, Alzheimer's disease is more likely to occur.  Thought to be caused by an overabundance of a receptor on the microglia cells, called CD33. Past studies by the researchers showed that for CD33, these “connector” molecules are special sugars.These molecules are ferried around the cell by specialized proteins that help them find their appropriate receptors.  The protein-glycan combination is called a glycoprotein.  The researchers, to find out more about the glycoproteins, obtained brain tissue from five people who died of Alzheimer's disease and from five people.Among the many thousands of glycoproteins they gathered from the brain tissues, only one connected to CD33. What was this mysterious glycoprotein?The researchers determined the protein component's identity by taking its “fingerprint” using mass spectroscopy, which identifies protein building blocks. Then they compared the molecular makeup of the protein with a database of known protein structures. The research team was able to conclude the protein portion of the glycoprotein was receptor tyrosine phosphatase (RPTP) zeta. Further experiments showed that the brain tissue of the five people who died with Alzheimer's disease had more than twice as much RPTP zeta S3L as the donors who did not have the disease. Implying that this glycoprotein may be connecting with more CD33 receptors than a healthy brain, limiting the brain's ability to clean up harmful proteins. Gonzalez-Gil Alvarenga, Ph.D., first author on the study stated:“Identifying this unique glycoprotein provides a step toward finding new drug targets and potentially early diagnostics for Alzheimer's disease.”   A Surprising Link Between Immune System and Hair Growth | Neuroscience News (07:36) Salk scientists have uncovered an unexpected molecular target of a common treatment for alopecia, a condition in which a person's immune system attacks their own hair follicles, causing hair loss. Corresponding author of the study, Ye Zheng, associate professor in Salk's NOMIS Center for Immunobiology and Microbial Pathogenesis, stated:“For the longest time, regulatory T cells have been studied for how they decrease excessive immune reactions in autoimmune diseases … Now we've identified the upstream hormonal signal and downstream growth factor that actually promote hair growth and regeneration completely separate from suppressing immune response.” Initially the researchers were interested in researching the roles of regulatory T cells and glucocorticoid hormones in autoimmune diseases.They did not function together to play a significant role in any of these conditions.  Thought they'd have more luck looking at environments where regulatory T cells expressed particularly high levels of glucocorticoid receptors The glucocorticoid receptor (GR, or GCR) also known as NR3C1 (nuclear receptor subfamily 3, group C, member 1) is the receptor to which cortisol and other glucocorticoids bind. The scientists induced hair loss in normal mice and mice lacking glucocorticoid receptors in their regulatory T cells.After two weeks, the researchers saw the normal mice grew their hair back, while the ones lacking the receptors struggled to grow it back The findings suggested that some sort of communication must be occurring between regulatory T cells and hair follicle stem cells to allow for hair regeneration.They continued to investigate how the regulatory T cells and glucocorticoid receptors behaved in skin tissue samples. They found that glucocorticoids instruct the regulatory T cells to activate hair follicle stem cells, which leads to hair growth. Depends on a mechanism whereby glucocorticoid receptors induce production of the protein TGF-beta3, all within the regulatory T cells. TGF-beta3 then activates the hair follicle stem cells to differentiate into new hair follicles, promoting hair growth.  This study revealed that regulatory T cells and glucocorticoid hormones are not just immunosuppressants but also have a regenerative function. Next, the scientists will look at other injury models and isolate regulatory T cells from injured tissues to monitor increased levels of TGF-beta3 and other growth factors.     Engineers devise clever system for EVs to share charge—while driving | Anthropocene (13:34) The charging station expansion isn't keeping up with the growing number of EVs on the road.The number of EVs on the road per public charging point globally rose to 9.2 at the end of last year, from 7.4 at the end of 2020, according to a study by BloombergNEF analyst Ryan Fisher on the state of public charging infrastructure. In a new study, engineers propose a way around this conundrum: EVs that share charge with each other while driving. In their vision, cars with low batteries could buy some charge from others with extra to spare, all without stopping. Could be orchestrated via a cloud-based control system Electrical and computer engineer Prabuddha Chakraborty the University of Florida and his colleagues propose a two-battery system for EVs.A large, slow-charging lithium-ion battery would drive the car,  A smaller, fast-charging battery would be used for on-the-go charging.  Once powered up, the small battery would transfer its charge to the car's main battery.  “Just like in your computer you have fast cache memory—but it's expensive—so you have other type of high-capacity memories that are slower,” said Tamzidul Hoque, a professor of electrical engineering and computer science at the University of Kansas The cloud-based system idea:Monitor charge levels of electric cars.  If a car's power is starting to run low, the network would alert it to other cars nearby with enough charge to sell.  Once two cars are matched with owner consent, cables would connect them for charging and they would be locked at the same speed until the power transfer is complete. Yet even in a well-planned, dynamic peer charging network, the researchers found in simulations that the total charge of the network will slowly deplete.To try to get around this idea, they propose the concept of mobile charging stations: large battery-loaded trucks that would recharge multiple vehicles at once.  Like military jets being refueled in-flight by tanker aircraft.  Using popular traffic modeling software they were able to simulate their idea somewhat.They found that it would eliminate range anxiety and re-charging wait time, and reduce EV cost by eliminating the need to have big batteries.   Scientists Use Vegetable Oil Byproduct to Remove Heavy Metals From Contaminated Water | EcoWatch (20:27) Scientists from Nanyang Technological University, Singapore, collaborating with ETH Zurich, Switzerland (ETHZ), have discovered a way to turn byproduct from vegetable oil production into a membrane that filters out heavy metals from water. Ali Miserez, study author and professor at Nanyang Technological University, stated:“Water pollution remains a major global issue in many parts of the world…Heavy metals represent a large group of water pollutants that can accumulate in the human body, causing cancer and mutagenic diseases. Current technologies to remove them are energy-intensive, requiring power to operate, or are highly selective in what they filter.” The researchers noticed that proteins in peanut and sunflower oil waste byproducts, called oilseed meals, were useful in attracting heavy metal ions.Turned the oilseed meals' proteins into nano-sized protein amyloid fibrils, which strongly attract heavy metal ions.  Combined these amyloid fibrils with activated carbon and tested the filters on three types of metal: platinum, chromium and lead. The membranes were 99.89% effective at filtering out all of the heavy metals from water, with the best results for platinum and lead. The membrane made from waste byproduct proteins is a low-cost option that requires little energy for decontamination, and the researchers say this innovation could work all over the world for water purification.  “Recovering precious platinum, which costs US$33,000/kg, only requires 32 kg of protein, while recovering gold, which is worth almost US$60,000/kg, only requires 16 kg of protein. Considering that these proteins are obtained from industrial waste that is worth less than US$1/kg, there are large cost benefits,” Miserez explained. Because of the simple technology, this filtration membrane is readily scalable, according to the researchers.   Tesla launches new virtual power plant that pays Powerwall owners to help end brownouts | Electrek (25:30) Tesla has launched a new virtual power plant in partnership with PG&E in California that will pay Powerwalls owners to help stabilize the electric grid and end brownouts in California. What is a virtual power plant?Consists of distributed energy storage systems, like Tesla Powerwalls, used in concert to provide grid services and avoid the use of polluting and expensive peaker power plants. Tesla has partnered with PG&E to launch a new version of its virtual power plant that will actually compensate people participating:The company's statement: “Become a part of the largest distributed battery in the world and help keep California's energy clean and reliable. Opt-in to the Tesla Virtual Power Plant (VPP) with PG&E and your Powerwall will be dispatched when the grid needs emergency support. Through the Emergency Load Reduction Program (ELRP) pilot, you will receive $2 for every additional kWh your Powerwall delivers during an event. Adjust your Backup Reserve to set your contribution, while maintaining backup energy for outages.” Depending on the events and the number of Powerwalls homeowners have, they could earn anywhere from $10 to $60 per event or even more for bigger systems. The extra capacity your Powerwall provides could help avoid or reduce blackouts in a severe emergency. This way, Powerwall can keep the lights on for both you and your community. Tesla said that it has about 50,000 Powerwalls that could be eligible for this VPP, which add up to a significant 500 MWh of energy capacity than can be distributed in any event.

The divide between the Covid vaccine haves and have-nots has been described as “criminal”, with only 20% of people in low and middle income countries having had one dose, compared with 80% in higher income countries. Countries with high vaccination rates have been called on to give up their place in the vaccine queue. The dual-track global vaccination programme has led to real anger, made worse by announcements of booster programmes in richer countries (despite the World Health Organisation calling for such plans to be put on hold). Claudia Hammond and her panel of global experts discuss the scale of vaccine inequity and consider whether evidence of waning vaccine immunity justifies the rollout of booster jabs, or if the soundest scientific case dictates everybody in the world should be vaccinated first. Claudia's guests include Dr Yodi Alakija, co-chair of the African Union's Delivery Alliance for Covid-19 in Abuja, Nigeria, Dr Maria Van Kerkhove, the World Health Organisation's Technical Lead for Covid in Geneva, Switzerland and two world leading immunologists, Dr Peter Openshaw, Professor of Experimental Medicine at Imperial College, London, UK and Dr Akiko Iwasaki, Professor of Immunobiology and Molecular, Cellular, and Developmental Biology at Yale University in the US.

Dr. Loving's degrees: B.S. Iowa State University, Zoology (2001), Ph.D. Iowa State University, Immunobiology (2006), Postdoc - Food and Drug Administration, Bethesda, MD (2006-2008). Research interests: My research objectives include identifying critical interactions between commensal intestinal microbiota and the developing immune system that contribute to a balanced and healthy pig. This understanding will lead to the development of intervention strategies to limit in-feed antibiotic use and colonization with foodborne pathogens. My laboratory is interested in better understanding the immune cells and molecules that interact with the microbiota throughout the intestinal tract, with a particular focus on the ileum and cecum. These locations harbor very distinct immune cell populations and organisms, and are unique niches for identifying mechanisms in which these two co-evolved systems interact to maintain a balanced and healthy intestinal ecosystem. We are also interested in immunometabolism as a biomarker of animal health and have been exploring change in lymphocyte metabolism under different feed and health conditions. We use various immunological assays and tools to assess the phenotype of immune cell populations and function (cytokine expression, proliferation, metabolism), as well as different husbandry conditions (dietary components, immunomodulators, lactogenic immunity) to monitor intestinal physiological and immunological responses. My research has also focused on evaluating the immune response associated with protective immunity against influenza virus in pigs, with an emphasis on identifying correlates of protection associated with live-attenuated influenza virus vaccination. In addition, I've worked on evaluating immune responses following administration of various alternatives to antibiotics to limit disease in swine, including different vaccine platforms and various immunomodulators. *This podcast is operated by Swine Impact, a Swine it Company.

He highlights Dr. Richard Simpson PHD's article Titled: Exercise, Immunity, and the COVID-19 Pandemic. Dr. Simpson's research interests are concerned with the effects of aging, stress and exercise on the immune system. He is an associate professor in the Departments of Nutritional Sciences, Pediatrics and Immunobiology at the University of Arizona. You can read it in it's entirety here. https://www.acsm.org/blog-detail/acsm-blog/2020/03/30/exercise-immunity-covid-19-pandemic. It is a good read that lays out in layman's terms the impact that exercise has on our immune function. Simpson writes in his blog, "Having higher age and sex-adjusted scores for cardiorespiratory fitness and performing regular exercise of moderate- to vigorous-intensity exercise that fall within ACSM (American College of Sports Medicine) guidelines has been shown to improve immune responses to vaccination, lower chronic low-grade inflammation, and improve various immune markers in several disease states including cancer, HIV, cardiovascular disease, diabetes, cognitive impairment and obesity. The ongoing COVID-19 pandemic has raised a lot of questions regarding how exercise can protect us from infection by boosting immunity.” The blog also goes on to highlight: “Compounding this problem are the known negative effects of social isolation and confinement on immunity. Glucocorticoids such as cortisol are elevated during periods of isolation and confinement and can inhibit many critical functions of our immune system. When we are stressed, the ability of our T-cells to multiply in response to infectious agents is markedly reduced, as is the ability of certain effector lymphocytes (e.g., NK-cells and CD8+ T-cells) to recognize and kill cells in our body that have become cancerous or have been infected with viruses. It is also vitally important that our immune cells maintain their ability to redeploy so that they may ‘patrol' vulnerable areas in or body (e.g., the upper respiratory tract and the lungs) to prevent viruses and other pathogens from gaining a foothold. This process is also important to minimize the impact of the virus and to expedite viral resolution should we become infected. Brad gives tips to improving your cardiorespiratory fitness by getting your heart rate within 50-65% of your target heart rate max for 30-45 minutes for 3-5x/wk if not all days. If you are not sure how to calculate this, see the SportSquire Episode, The Benefits of Training Within Your Different Target Heart Rates. Brad continues to encourage the SportSquire Community to explore, engage, and learn as this is foundational to empowering real behavioral change on your wellness journey. He encourages those who are interested to look into some of the scholarly articles to read about the progressive research findings specifically related to Exercise Immunology.

In this bonus episode of Where Cures Begin, we hear about the parallels between polio and COVID-19, and how Salk is responding to the pandemic, from faculty in Salk's NOMIS Center for Immunobiology and Microbial Pathogenesis. Professor Susan Kaech aims to understand how memory T cells are produced during infection and vaccination, how they function and why they can fail to induce long-term immunity, particularly during chronic disease or cancer. Professor Greg Lemke discovered a family of proteins called TAM receptors, which play a crucial role in regulating the response of the immune system to infection from bacteria, viruses and other pathogens. Professor Martin Hetzer is Salk's VP/CSO, responsible for providing leadership in developing and implementing Salk’s overall scientific strategy, as well as overseeing research operations in support of that strategy. Additionally, his lab uses a variety of techniques to pose questions about how the human genome is organized inside a cell’s nucleus.

Professor John Hogenesch studies circadian rhythms and the genome. He talks about The influence of cues on our circadian rhythm and how lighting and even medication timing can affect us, Studies on hospital-specific lighting and how two new hospital wings in Cincinnati are designed accordingly, and Some unusual sleep patterns, such as Delayed Sleep Phase Syndrome, and how it can affect people.  Dr. John Hogenesch is Professor of Pediatrics at Cincinnati Children's Hospital Medical Center in Human Genetics and Immunobiology at the University of Cincinnati Department of Pediatrics. He specializes in genome biology with a focus on the molecular mechanisms of circadian rhythms in mammals. He explains to listeners the basics of circadian rhythm as a daily rhythm of behavior and physiology that persists in the absence of external cues. He discusses how healthcare and specifically hospital design and schedules are often at odds with most patients' rhythms. In fact, he mentions one study in which NICU patients under a cycled light schedule went home two weeks earlier than babies under constant dimmed light conditions. He discusses his hospital's design of two new areas for NICU and PICU patients under the advisement of his lab that will integrate beds with circadian natural-light systems. He adds ways in which medication delivery and procedure timing could also be better paired with circadian rhythms and efforts to do so. Dr. Hogenesch also talks about Delayed Sleep Phase Syndrome (DSPS). Richard has such a sleep pattern and the two discuss how it manifests itself, as well as other sleep patterns, and how they affect those who experience them. He also addresses how cortisol's peak has an effect as well as how external cues interfere or work with our sleep patterns. For example, he mentions our eating timing, light exposure, and light temperature and type. He discusses how the pandemic is pushing many of us to later sleep schedules and possible hypothesizes for why. Along the way he offers some suggestions for eliminating excessive blue and green light and other similar measures.  For more, see his lab page at cincinnatichildrens.org/research/divisions/h/genetics/labs/hogenesch and the Society for Research in Biological Rhythms, which publishes helpful blog posts and articles.

Transplants without Immunosuppressant Drugs: UCSF's Transplant and Stem Cell Immunobiology Lab

Sonja Schrepfer Bio: Sonja Schrepfer, M.D., Ph.D., Professor of Surgery, founded the Transplant and Stem Cell Immunobiology (TSI) Lab in 2009 in Germany. In 2015, she joined the faculty of the Department of Surgery at the University of California San Francisco and was Director of the TSI Lab at UCSF. Sonja is scientific co-founder of Sana Biotechnology Inc. which she joined as SVP in 2019. Dr. Schrepfer's research career has been dedicated to making fundamental discovers in transplant and stem cell immunobiology. Pluripotent stem cell (PSC)-based approaches are effective in immunosuppressed/deficient animal models; but in humans, systemic immunosuppression cannot be justified, due to severe side effects and significant risk of infections and malignancies. So far, only a few immunological strategies have been proposed to overcome these hurdles. Work by Dr. Schrepfer is at the forefront of PSC immunobiology and paves the way for treatment of a wide range of diseases – from supporting functional recovery of failing myocardium to the derivation of other cell types to treat diabetes, blindness, cancer, lung, neurodegenerative, and related diseases. She spent many years examining in detail the fetomaternal interface for application to the envisioned cell therapy. Her work with one of the most antigenic phenotypes, antigen-presenting endothelial cells, demonstrates that hypo-immunogenic cells reliably evade immune rejection in allogeneic recipients that are entirely mismatched in their major histocompatibility complex profile, and further, these cells show long-term survival without immunosuppression in mice and humanized mice (published in Nature Biotechnology in 2019). Sonja is currently Adjunct Professor at UCSF investigating the immunobiology in “tissue chips in space”; that is sending tissue chips to the international space station (ISS). She participated in three flight missions as collaborator and was the PI on the SpaceX16 mission (December 2019). This research will provide insight into what physiological effects time in outer space might have on astronauts, with potentially important implications for future longer-term missions, and has the possibility to open the door to fascinating new discoveries that could be used in earth-bound immunology research. Tobias Deuse Bio: Tobias Deuse, M.D. is a cardiac and heart and lung transplant surgeon internationally renowned for his pioneering work in the development of minimally-invasive techniques for mitral valve repair.  Dr. Deuse graduated the University of Stuttgart (Germany) in 1994 with a BS in Physics, and in 2000 earned an M.D. from University of Wuerzburg. Dr. Deuse thereafter received advanced training in cardiothoracic surgery at the University Hospital Munich-Grosshadern and University Heart Center Hamburg-Eppendorf. After obtaining his board certification in Germany in 2007 as a heart surgeon, Dr. Deuse completed a surgical fellowship in Lung and Heart-Lung Transplantation at Stanford and joined the UCSF faculty in 2015. Dr. Deuse's laboratory at UCSF is working on the immunobiology of pluripotent stem cells. To circumvent rejection, techniques such as somatic cell nucleus transfer (SCNT) into an enucleated oocyte (formation of a SCNT stem cell), fusion of a somatic cell with an embryonic stem cell (ESC; formation of a hybrid cell), and reprograming of somatic cells using certain transcription factors (induced PSCs, iPSCs) have been used. However, his work has shown that SCNT stem cells and iPSCs may have immune incompatibilities with the nucleus or cell donor, respectively, despite having identical nuclear DNA (published in Cell Stem Cell 2014). Further, he has demonstrated that mitochondrial (mt) DNA-encoded proteins as well as mtDNA mutations and genetic instability associated with reprograming and iPSC expansion can create minor antigens, producing rejection. His work also demonstrated that even autologous iPSC derivatives are not inherently immunologically inert for autologous transplantation (published in Nature Biotechnology in 2019). This has provided an important, promising avenue for selection of optimal stem cell therapeutics for future clinical applications ¾ via identifying the most compatible starter cell line and monitoring “near match” autologous iPSC products for mtDNA mutations and single nucleotide polymorphism (SNP) enrichments during the manufacturing process. Director Sonja Schrepfer, M.D., Ph.D., and co-director Tobias Deuse, M.D., explain the lab's research towards understanding and overcoming transplant rejection. They touch on Why finding ways to reduce rejection and successfully find transplantation avenues that don't require immunosuppression drugs is so important, How their research starts with pluripotent stems cells that must be differentiated and then transplanted,  Why using a patients' specific stem cells still face rejection due to mitochondrial proteins that eventually form despite gene editing, and How the lab is working toward an "off the shelf" solution by altering proteins that trigger rejection and other means. Drs. Schrepfer and Deuse run the Transplant and Stem Cell Immunobiology Lab (TSI) at the University of California in San Francisco and specialize in heart and lung transplant issues through CRISPR, gene editing,and stem cell therapy. They begin by explaining the many complications a person taking immunosuppressant drugs faces and why their research seeks to address these issues and make for a safer system for patients. Further, they explain that patient-tailored stem cell therapy approaches are not suitable for large populations for several reasons, including the frequent need to treat a patient almost immediately for heart damage or other similar issues. They explain that while they can generate cardiac cells that don't get rejected at first, these cells can develop mutant proteins that causes rejection later. They are following a couple of approaches to address the rejections including learning how fetuses survive the mother's immune system. A big leap forward for the lab was learning how to knock out the molecule that signaled to the immune system its foreignness through CRISPR: in other words, they are learning how to make these introduced cells silent to the immune system. Finally, they describe their "off the shelf" goal of producing non-immunogenic cells ready for injection for a majority of patients and alternatively generating a hypo-immunogenic environment in the patient to prevent long-term rejection.

In this episode of the Epigenetics Podcast, we caught up with Dr. Andrew Pospisilik from the Van Andel Institute in Grand Rapids, Michigan to talk about his work on the epigenetic origins of heterogeneity and disease. Dr. Andrew Pospisilik worked at the Max-Planck Institute of Immunobiology and Epigenetics in Freiburg for 8 years and in 2018 he joined the Van Andel Institute as the director of its Center for Epigenetics. At the Van Andel Institute his research focuses on diabetes, neurodegenerative diseases, cancer, and obesity. The goal of the Pospisilik laboratory is to better understand epigenetic mechanisms of these diseases and the roles of epigenetics in disease susceptibility and heterogeneity.   These areas of medicine are among the most important public health challenges, with the latest estimates suggesting that they impact more than 1 billion people worldwide. Although these diverse conditions are all very different, they are now thought to be caused, at least partially, from alterations in the epigenetic mechanisms that regulate gene expression and metabolism. This interview covers recent work from the Pospisilik lab on the epigenetics of these complex diseases.    References https://pospisiliklab.vai.org/ J. Andrew Pospisilik, Daniel Schramek, … Josef M.

Can Genistein Help Heal Hashimoto’s Disease and Hypothyroidism? In the fall of 2016, a study was conducted in China and published in the medical journal Immunobiology. The researchers looked at the compound genistein and Hashimoto's disease to see if it affected thyroid function in patients with Hashimoto’s thyroiditis.  The research paper was entitled, “Genistein improves thyroid function in Hashimoto’s thyroiditis patients through regulating Th1 cytokines.”  To clarify, “Th1 cytokines” refer to a type of thyroid-helper cells that indicate how much inflammation there might be in the thyroid gland.  In other words, they are markers of inflammation. The results of this study were very exciting so you might want to pay close attention. What is genistein? Genistein is an isoflavone which is a plant-derived compound with estrogenic activity.  It falls in the class of phytoestrogens and is found in soybeans.  Clinical studies in the past have demonstrated that this compound has immune-regulating properties by exerting anti-inflammatory effects in certain health conditions including encephalomyelitis (inflammation of the brain and spinal cord), cardiac inflammation resulting from diabetes, coronary obstructive pulmonary disease (COPD) and other serious diseases. In this study, Zhang and four of his colleagues began by pointing out that Hashimoto’s thyroiditis is now considered the most common autoimmune disease in the world.  It is believed that excessively stimulated thyroid-helper cells play the main role in giving rise to the autoimmune condition in Hashimoto’s thyroiditis patients.  While conventional treatment has typically addressed only the symptoms of the illness via oral administration of a thyroid hormone replacement, the fact remains that there is still an autoimmune condition in Hashimoto’s thyroiditis which can be a concern. Why is it problematic for an autoimmune condition to persist in an individual with Hashimoto’s disease? Previous studies have demonstrated that in those with fully or partially functional thyroid glands but not “fully hypothyroid Hashimoto’s patients”, long-term Hashimoto’s thyroiditis closely correlated with the prevalence of thyroid cancer. Chronic inflammation is never beneficial for the body so if someone is invested in his or her health, mitigating any autoimmune condition would be prudent.  In this investigation, the researchers wanted to evaluate any beneficial anti-inflammatory properties of genistein for those with Hashimoto’s thyroiditis and examine what impact it might have on the chronic inflammatory condition associated with Hashimoto’s disease. How was the study done? Two-hundred eighteen female subjects between the ages of 20 and 80 were recruited, all with Hashimoto’s thyroiditis. These requirements had to be met in the subjects: 1. Normal levels of free T3 and free T4 with or without thyroid replacement therapy 2. Normal TSH levels or slightly elevated TSH levels below 20 mU/L 3. Increased blood levels of thyroid antibody (thyroid peroxidase) greater than 100 U/mL Subjects with any of the following conditions were excluded: 1. Prior use of immunoregulators 2. Presence of infection 3. Presence of thyroid nodules 4. Thyroid hypoplasia 5. Prior treatment with radioiodine 6. Pregnancy 7. Presence of serious illnesses such as cancer, kidney or liver failure. The 278 females with Hashimoto’s were split into two groups with 143 in the placebo group and 135 in the genistein group.  Patients in the genistein group were given 600 mg per day of genistein as a purified soy extract taken orally for thirty days. What lab work was required? To measure thyroid function: 1. TSH 2. T3 3. T4  (total T4) 4. fT4 (free T4) To measure thyroid antibody levels: 1. Thyroid peroxidase - TPOAb 2. Thyroglobulin – TgAb To measure inflammation: Thyroid-helper cell bodies (Th1 and Th2) which we will refer to henceforth as inflammatory markers.

Ante un golpe o inflamación, pensamos que un medicamento es la mejor forma para reducir la inflamación y curar más rápido el golpe pero lo que no sabemos es que hay remedios naturales que nos pueden ayudar mucho a reducir la inflamación de una determinada zona y además nos evitaran problema secundarios en el estómago, sistema digestivo, etc. Desde un dolor de cabeza pasando por dolor de espalda, esguinces, migrañas, osteoartritis, etc. podemos reducir el dolor y la inflamación de forma natural con plantas medicinales. En función del tipo de elemento del que se componga, podemos encontrar inflamatorios naturales como alimentos para comer, cremas para ponernos en la zona afectada o incluso en forma de té para tomar calentito cuando deseemos. Para hablaros de todos ellos nosotros hemos clasificado los antiinflamatorios en los siguientes tipos: El primero de los que vamos a hablar son las plantas, que sirven de base para hacer cremas antiinflamatorias naturales como la crema de árnica Galius o sirven para hacerse tés caseros. Y alimentos con propiedades antiinflamatorias para que los podáis añadir a vuestra dieta. Comencemos: Cúrcuma Esta especia está formada principalmente por un componente activo llamado curcumina. La curcumina es un colorante natural procedente de la cúrcuma. Algunos de los productos en los que la podemos encontrar como colorante son: mantequillas, quesos, productos de pastelería y licores. El colorante de la cúrcuma se absorbe relativamente poco en el intestino, y lo que es absorbido se elimina rápidamente por vía biliar, por ello se combina (casi en cantidades iguales) con pimienta negra que aumenta 2000 veces su absorción. Alta acción antiinflamatoria y analgésica que puede ayudar a aliviar diferentes patologías. Las propiedades antiinflamatorias de la cúrcuma hacen de esta planta un remedio efectivo para aliviar los síntomas y el dolor de afecciones como: 1. La artritis reumatoide. 2. Osteoartritis. 3. Colitis ulcerosa. 4. Uveitis anterior crónica. 5. Dolor en las articulaciones. 6. Dolores de espalda. Mejora la digestión Cuenta con propiedades carminativas gracias a agentes activos como el eugenol y el zinzibereno, los cuales ayudan a aliviar cólicos flatulentos al estimular la eliminación de gases del intestino. En particular, la cúrcuma está considerada como una especia digestiva, ya que estimula la secreción de moco gástrico y mejora la digestión de los alimentos. Protege de enfermedades cardiovasculares Tiene propiedades cardioprotectoras al disminuir los efectos del estrés oxidativo causado por los radicales libres. Su capacidad para incrementar las enzimas antioxidantes podría ser beneficiosa para reducir el riesgo de desarrollar enfermedades del corazón. También ha demostrado evitar la coagulación de la sangre, lo que ayuda en la prevención de enfermedades como la aterosclerótica vascular o la aterosclerosis. Apoyado con una buena alimentación, su consumo podría resultar bueno para controlar los niveles de colesterol y triglicéridos. Protege el hígado Antidepresivo Fortalece las defensas del cuerpo Es una fuente de vitaminas y minerales que fortalecen el sistema inmunológico para aumentar las defensas contra los virus y bacterias que causan infecciones. Harpagofito El Harpagofito, también conocido popularmente como garra del diablo o uña del diablo, es una planta originaria de África, que contiene varios principios activos que son los que le confieren sus propiedades medicinales. Algunos de estos componentes son los iridoides, triterpénicos, flavonoides o fenilpropanos. Esta planta medicinal tiene acción digestiva, antiinflamatoria, analgésica, colérica, depurativa, antimiálgica, antifebril, antidiabética, estimulante del apetito, hipoglucemiante, antioxidante. Usos y beneficios del Harpagofito • Mejora las digestiones • Alivia los dolores • Es efectiva para el dolor de cabeza • Es beneficioso para la vejiga • Reduce el colesterol en sangre • Mejora el movimiento articular • Ayuda a evitar la arterioesclerosis • Está indicada para problemas gastrointestinales • Depura el organismo • Reduce los niveles de azúcar en sangre • Reduce la inflamación y la hinchazón • También combate la arteriosclerosis, la artralgia y el reúma. En casos de osteoartritis se combina con el ácido hialurónico, un polisacárido de poder regenerador. Arnica El árnica normalmente se puede encontrar en forma de pomada, crema, gel o aceite, y se utiliza para la curación de moretones, esguinces, dolor de músculos, hinchazones y en general, cualquier problema que esté relacionado con los huesos, los tendones o los músculos.

This study investigated the immunobiology of MOG-induced EAE in the DA rat, an animal model, which reproduces the immunopathology of the type II MS lesion (Lucchinetti et al., 2000). A newly established immunisation protocol results in a highly synchronised biphasic form of EAE, which mimics the disease course of secondary progressive MS, albeit in a strongly abbreviated time course (Figure 3.1.1). This study demonstrates that MOG-specific autoantibodies are responsible for initiating clinical relapse and driving disease progression. On the background of mild, sub-clinical inflammatory activity in the CNS, pathogenic antibodies enter the CNS and mediate demyelination, a process that in turn amplifies the local inflammatory response (Figure 3.1.14 A). It should however be noted that lethal clinical relapses may also occur in the absence of a pathogenic antibody response if an inflammatory lesion develops in a region of the CNS that is particularly sensitive to damage, or where it may perturb vital functions, such as the brain stem. Although antibodies have been shown to amplify the severity of ongoing clinical EAE (Schluesener et al., 1987; Linington et al., 1988; Lassmann et al., 1988), firm evidence for a role in driving relapse and disease progression was missing. This study has now established this principal, which in all probability is relevant to our understanding of the pathogenesis of severe, steroid non-responsive relapses in MS patients. However, this model of EAE is an artificial system, in which the role of antibody is only apparent because of the different kinetics of MOG-specific T and B cell responses. In MS we still have to answer two crucial questions, namely the identity of the autoantigens targeted by the demyelinating antibody response, and the factors that may trigger this response. MOG is the only myelin protein known to initiate a demyelinating antibody response in EAE, and MOG-induced EAE has provided a valuable tool to identify the role of pathogenic autoantibodies in immune mediated demyelination. However, there is a major discrepancy between the proportion of MS patients with pathogenic MOG-specific antibodies in their circulation (5%; Haase et al., 2000) and the frequency of patients with pathological changes suggestive of antibody-mediated pathomechanisms (>50%; Lucchinetti et al., 2000). This discrepancy may in part be accounted for by the absorption of the pathogenic antibodies into the CNS, which will lead to a dramatic reduction of the antibody titre in the periphery, as demonstrated in section 3.1.3.4 of this study. On the other hand, it is unlikely that MOG is the only target autoantigen, which is exposed on the myelin surface and can therefore initiate a demyelinating autoantibody response. The identification of potential targets is a prerequisite to develop diagnostic kits to identify those patients with pathogenic autoantibody responses and then provide an appropriate therapy such as plasma exchange, or immuno-absorption. As demonstrated in this study, DNA vaccination using a plasmid encoding a myelin antigen is one approach to generate high titre autoantibody responses directed against the native protein. The pathogenicity of this antibody response can then be assayed in the same animal by inducing EAE. This method circumvents problems such as purity, yield and denaturation, all of which complicate any study using antigens isolated from the CNS or generated using recombinant technologies. Coupling this approach to a proteomics based analysis of the myelin membrane and reverse genomics to identify candidate gene products provides the means to map out those protein antigens that can be targeted by a demyelinating autoantibody response. The feasibility of this concept is currently being tested in the rat using PLP and MAG as myelin components that may in certain circumstances provoke a pathogenic autoantibody response. Such an analysis will, however, not detect pathogenic antibody responses to glycolipid antigens, which are major target autoantigens in a number of diseases affecting the peripheral nervous system such as Guillain Barré syndrome (GBS). In GBS a pathogenic antibody response to gangliosides appears to be triggered by infections with particular serotypes of Campylobacter jejuni (Fredman, 1998; Willison and O´Hanlon, 1999). In the majority of patients these antibody responses are an acute phenomenon and disappear as the patients recover (Hahn, 1998). It is conceivable that a similar mechanism is responsible for the initiation of severe relapses in some MS patients, if an infection triggers a cross-reactive antibody response to a surface glycolipid epitope. This would induce an episode of acute CNS demyelination that would not be immediately responsive to immunosuppressive therapy, as tissue damage and amplification of the local inflammatory response would be driven by the pre- existing antibody response. Analysis of the autoantibody responses in MS should therefore be extended to examine lipid as well as protein autoantigens. Such studies should also not be restricted to myelin, but also address the question of responses to other structures such as the axon and oligodendrocyte progenitor cells. Such autoantibody responses are however only conditionally pathogenic, in other words their pathogenic potential is only expressed if they can enter the CNS across the blood brain barrier (BBB)(Litzenburger et al., 1998; Bourquin et al., 2000). In EAE the inflammatory insult to the CNS is responsible for the disruption of BBB function and the entry of antibody into the nervous system. MS is characterised by repeated episodes of CNS inflammation but what initiates and maintains this response is unclear. The observation, that DA rats develop a similar, although eventually self-limiting response in the CNS after immunisation with MOG-peptide in CFA provides a model to investigate the immuno-regulatory deficit(s) responsible for chronic CNS inflammation. The disease model is very reproducible with >90% of animals relapsing after peptide immunisation as opposed to
