In this episode of Discovery Matters, hosts Dodi and Conor explore how synthetic biology can lead to transformative breakthroughs when it comes to dealing with global health problems. Through their conversation with Justin Vigar, a PhD student in Dr. Keith Pardee's lab at the University of Toronto in Canada, we learn how his paper-based diagnostic tool has the potential to provide faster, more cost-efficient, and accessible diagnostics for underserved locations. This is complemented by Amir Pandi and Tobi Erb's discussion of using AI and synthetic biology to develop new antimicrobial peptides.

En el episodio de hoy, hablo de la lesión medular y el entrenamiento con sistemas de soporte de peso corporal, una modalidad de tratamiento que cada vez está más en boga y que parece realmente que tiene su lugar asentado dentro de la rehabilitación de la lesión medular. Normalmente colocamos un arnés al paciente, que se une a una máquina que descarga el peso en un cierto porcentaje. Esa idea se cumple a la perfección en el caso de las grúas pero si pensamos en un paciente que quiere caminar, parece que quitarle peso, no es suficiente. ¿Hay algo más en estos sistemas de soporte de peso? ¿Qué hay de interacción humano-máquina? En este episodio, vemos estudios en sujetos sanos y en lesionados medulares, describimos sistemas de soporte de peso y aportamos ideas prácticas para terapia.

This episode: A cancer-killing virus could help increase success of treatment of a form of eye cancer in children! Download Episode (8.0 MB, 8.7 minutes) Show notes: Microbe of the episode: Acanthamoeba polyphaga mimivirus News item Takeaways Cancer obviously is a serious concern, and can be tricky to treat because there are endless varieties in all different places in the body, each of which can have its own expected progression, aggressiveness, and methods of treatment to take into account. Even more serious is when the cancer is in very young children, as is often the case with a cancer of the eye called retinoblastoma. There are about 8000 cases of this disease per year, and when treatment is unsuccessful, it can lead to the loss of one or both eyes. In this study, investigators looked into using a cancer-targeting, oncolytic virus to complement the normal treatment of chemotherapy. The virus for the most part remained localized to the eye where it should be, and targeted the cancer instead of healthy cells, and so seems promising. In the small trial with two patients included in this study, the virus didn't cause a complete recovery, but showed some modest promising results.

Esse artigo foi publicado na revista científica Science Advances em fevereiro de 2018 com o título “A commensal strain of Staphylococcus epidermidis protects against skin neoplasia”. No quadro Microlitros de Notícias: uma breve pipetada de novidades da Microbiologia e Imunologia, abordamos os seguintes assuntos: a atividade do leite materno no combate à células tumorais; a utilização de bactérias vampiras contra infecções bacterianas; a descoberta de uma enzima bacteriana capaz de degradar plásticos; e algumas dicas sobre a febre amarela. Na Filogenia da Ciência, iremos trazer a história de um pesquisador muito importante para nós do Instituto de Microbiologia, o professor Paulo de Góes.   Tópicos comentados nesse episódio Microbiota Staphyloccocus epidermidis Atividade antimicrobiana Molécula 6-HAP Fármacos antitumorais Quimioterápico Tumores Prevenção do câncer de pele Leite materno no combate à células tumorais Bactérias vampiras contra infecções bacterianas Enzima bacteriana capaz de degradar plásticos Dicas sobre a febre amarela A vida de Paulo de Góes e do Instituto de Microbiologia/UFRJ   Referências desse episódio Nakatsuji T, Chen TH, Butcher AM, Trzoss LL, Nam SJ, Shirakawa KT, Zhou W, Oh J, Otto M, Fenical W, Gallo RL.

Vamos utilizar uma linguagem bem acessível para destrinchar esses artigos para vocês, mas sem perder o rigor científico e analítico necessário para essa tarefa. Além de discutir artigos nós teremos o quadro Microlitros de Notícias, onde nossos microbiologistas e imunologistas de plantão irão abordar pequenas reportagens e trazer novidades para vocês. No quadro filogenia da Ciência vamos contar um pouco sobre a vida de grandes personalidades que revolucionar...

Understanding and managing your patient’s pain can be extremely difficult. Liam West spoke to Dr. Tasha Stanton to tap into her vast expertise in the area of pain science. Dr. Stanton is a Senior Research Fellow for the “Body in Mind” group in Australia and has a background in physiotherapy, spinal biomechanics and pain neuroscience. Her work to date has led to several prestigious pain science awards. In this podcast she explains the disconnect between tissue damage and the pain experience, why people experience different levels of pain to the same stimulus and shares how to explain pain to a patient within a clinic setting.
