Abstract: X-ray tomography and x-ray fluorescence imaging are two non-invasive imaging techniques to study cellular structures and chemical element distributions, respectively. However, correlative X-ray tomography and fluorescence imaging for the same cell has yet to be routinely realized due to challenges in sample preparation and X-ray radiation damage. Here we report an integrated experimental and computational workflow for achieving correlative multi-modality X-ray imaging of a single cell. The method consists of the preparation of radiation-resistant single-cell samples using live-cell imaging-assisted chemical fixation and freeze-drying procedures, targeting and labeling cells for correlative x-ray tomography and x-ray fluorescence measurement, and computational reconstruction of the correlative and multi-modality images. With X-ray tomography, cellular structures including the overall structure and intracellular organelles are visualized, while X-ray fluorescence imaging reveals the distribution of multiple chemical elements within the same cell. Our correlative method demonstrates the feasibility and broad applicability of using X-rays to understand cellular structures and the roles of multiple chemical elements and related proteins in signaling and other biological processes.

Abstract: Cilia and flagella play a crucial role in the development and function of most eukaryotic organisms. The structural core of the flagellum, the axoneme, is conserved in most eukaryotes and careful regulation of dynein motors within the axoneme is required for proper ciliary beating. The sperm flagellum from the American eel (Anguilla rostrata) has been shown to lack many of the canonical axonemal proteins, including the radial spokes, the central pair complex, and possibly even the outer row of dynein arms, presenting a "minimal" flagellar system. Here, we present cryo-electron tomography analysis of the eel sperm flagellum. We identified two states for the eel sperm flagellum within our tomograms, narrow and wide, and found that the flagellum started narrow near the sperm head and widened distally. Subtomogram averages revealed that the eel sperm flagellum has retained remnants of the missing regulatory complexes, including a short radial spoke 3 complex, basal components of radial spokes 1 and 2, and an outer dynein arm docking complex. We also describe unique structural features of the A. rostrata sperm flagellum, such as a unique pattern of holes at the inner junction and an accessory complex located at the "outer" junction. Finally, we discuss the consequences of losing key regulatory factors for the eel sperm flagellum and hypothesize several evolutionary factors that may have led to their loss. Together, our results shed light onto the structure and function of the eel sperm axoneme and provide insight into the minimum requirements for proper ciliary beating.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.07.12.547497v1?rss=1 Authors: Kislinger, G., Fabig, G., Wehn, A. C., Rodriguez, L., Jiang, H., Niemann, C., Klymchenko, A. S., Plesnila, N., Misgeld, T., Mueller-Reichert, T., Khalin, I., Schifferer, M. Abstract: Like other volume electron microscopy approaches, Automated Tape Collecting Ultramicrotomy (ATUM) enables imaging of serial sections deposited on thick plastic tapes by scanning electron microscopy (SEM). However, ATUM is unique by enabling hierarchical imaging and thus efficient screening for target structures as needed e.g., for correlated light and electron microscopy. However, SEM of sections on tape can only access the section surface, thereby limiting the axial resolution to the typical size of cellular vesicles, an order of magnitude lower than the acquired xy resolution. In contrast, serial-section electron tomography (ET), a transmission electron microscopy-based approach, yields isotropic voxels at full EM resolution, but requires deposition of sections on electron-permeant thin and fragile monolayer films - thus making screening of large section libraries difficult and prone to section loss. To combine the strength of both approaches, we developed ATUM-Tomo, a hybrid method, where sections are first reversibly attached to plastic tape via a dissolvable coating, and after screening detached and transferred to the ET-compatible thin films. Thus, ATUM-SEM of serial semi-thick sections and consecutive ET of one selected section combines SEM's fast target recognition and coarse rendering capability with ET's high-resolution volume visualizations - thus enabling multi-scale interrogation of cellular ultrastructure. As a proof-of-principle, we applied correlative ATUM-Tomo to study ultrastructural features of blood brain barrier (BBB) leakiness around microthrombi in a mouse model of traumatic brain injury. Microthrombi and associated sites of BBB leakiness were identified by confocal imaging of injected fluorescent and electron-dense nanoparticles, then relocalized by ATUM-SEM, and finally interrogated by correlated ATUM-Tomo, a workflow which created a seamless zoom-in on structural BBB pathology from the micro- to the nanometer scale. Overall, our new ATUM-Tomo approach will substantially advance ultrastructural analysis of biological phenomena that require cell- and tissue-level contextualization of the finest subcellular textures.

Abstract: Antibody-based imaging techniques rely on the availability of high-quality reagents whose performance is evaluated for the specific application. Because commercial antibodies are validated for a limited number of uses, in many cases individual laboratories have to employ extensive in-house antibody testing. Here we present a novel strategy to efficiently identify candidate antibodies for array tomography (AT) by introducing an application-specific proxy screening step. AT is a serial section volume microscopy technique that enables quantitative analysis of the cellular proteome in a highly dimensional manner. To identify suitable antibodies for AT-based analysis of synapses in mammalian brain samples, we introduce a heterologous cell-based assay designed to simulate unique features of AT such as chemical fixation and resin embedding that are likely to influence antibody binding. The assay was included as part of the initial screening strategy to generate monoclonal antibodies that can be used for AT. This approach simplifies the screening of candidate antibodies and has high predictive value for identifying antibodies suitable for AT analyses. In addition, we have created a comprehensive database of AT validated antibodies with a neuroscience focus and show that these antibodies have a high likelihood of success for postembedding applications in general, including immunogold electron microscopy. The generation of a large and growing toolbox of antibodies for use in AT will further expand the use of this powerful imaging technique. Copy rights belong to original authors.

A., Ishikawa, T., Zuber, B., Ochsenreiter, T. Abstract: In contrast to many eukaryotic organisms, trypanosomes only contain a single mitochondrion per cell. Within that singular mitochondrion, the protist carries a single mitochondrial genome that consists of a complex DNA network, the kinetoplast DNA (kDNA). Segregation of the replicated kDNA is coordinated by the basal body of the cell's single flagellum. The tripartite attachment complex (TAC) forms a physical connection between the proximal end of the basal body and the kDNA. This allows anchoring of the kDNA throughout the cell cycle and couples kDNA segregation with the separation of the basal bodies prior to cell division. Over the past years, several components of the TAC have been identified. To shed light on the structure of the cytoplasmic part of the TAC (known as the exclusion zone), we performed cryo-electron tomography on whole cells. This allowed us to acquire three-dimensional high-resolution images of the exclusion zone in situ. We observed that the exclusion zone filaments offer great mechanical flexibility for basal body movement. We measured the dimensions of the individual structural elements of the area, as well as the overall orientation and positioning of the basal bodies towards the mitochondrial kDNA pocket. Using a combination of experimental data and modelling, we generated a structural model of the exclusion zone protein p197. Our findings suggest that the majority of p197 consists of a string of spectrin-like repeats. We propose that these structural units provide the architecture of a molecular spring and that they are required in the TAC to withstand the mechanical forces generated through basal body repositioning events during kDNA segregation and motility of the organism.

Abstract: Cilia are essential organelles that protrude from the cell body. Cilia are made of a microtubule-based structure called the axoneme. In most types of cilia, the ciliary tip is distinct from the rest of the cilium. Here, we used cryo-electron tomography and subtomogram averaging to obtain the structure of the ciliary tip of the ciliate Tetrahymena thermophila. We show the microtubules in the tip are highly cross-linked with each other and stabilised by luminal proteins, plugs and cap proteins at the plus ends. In the tip region, the central pair lacks the typical projections and twists significantly. By analysing cells lacking a ciliary tip-enriched protein CEP104/FAP256 by cryo-electron tomography and proteomics, we discovered candidates for the central pair cap complex and explain potential functions of CEP104/FAP256. These data provide new insights into the function of the ciliary tip and inform about the mechanisms of ciliary assembly and length regulation. Copy rights belong to original authors.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.11.19.517200v1?rss=1 Authors: Kirchweger, P., Mullick, D., Sawin, P. P., Wolf, S. G., Elbaum, M. Abstract: Cryo-electron tomography (cryo-ET) is the prime method for cell biological studies in three dimensions (3D) at high resolution. We have introduced cryo-scanning transmission electron tomography (CSTET), which can access larger 3D volumes, on the scale of 1 micron, making it ideal to study organelles and their interactions in situ. Here we introduce two relevant advances: a) we demonstrate the utility of multi-color super-resolution radial fluctuation light microscopy under cryogenic conditions (cryo-SRRF), and b) we extend the use of deconvolution processing for dual-axis CSTET data. We show that cryo-SRRF nanoscopy is able to reach resolutions in the range of 100 nm, using commonly available fluorophores and a conventional widefield microscope for cryo-correlative light-electron microscopy (cryo-CLEM). Such resolution aids in precisely identifying regions of interest before tomographic acquisition and enhances precision in localizing features of interest within the 3D reconstruction. Dual-axis CSTET tilt series data and application of entropy regularized deconvolution during post-processing results in close-to isotropic resolution in the reconstruction without averaging. We show individual protein densities in a mitochondrion-ER contact in a cell region 850 nm thick. The integration of cryo-SRRF with deconvolved dual-axis CSTET provides a versatile workflow for studying unique objects in a cell. Copy rights belong to original authors.

F., Liu, X. Abstract: We developed a new analytic tool based on visible-light optical coherence tomography fibergraphy (vis-OCTF) to longitudinally track individual axon bundle transformation following acute optic nerve crush injury (ONC) in mice. We analyzed four parameters: lateral bundle width, axial bundle height, cross-sectional area, and the shape of individual bundles. We showed that axon bundles became wider and thicker at 3-days post ONC. The bundle swelling at 3-days post-ONC has correlated with about 15% retinal ganglion cell (RGC) soma loss. At 6-days post-ONC, axon bundles showed a significant reduction in lateral width and cross-sectional area, followed by a reduction in bundle height at 9-days post-ONC. Bundle shrinking at 9-days post-ONC has correlated with about 68% RGC soma loss. Both experimental and simulated results suggested that the cross-sectional area of individual RGC axon bundles is more sensitive than the bundle width and height to indicate RGC soma loss. This study is the first to track and quantify individual RGC axon bundles in vivo following ONC injury and establish the correlation between the morphological changes of RGC axon bundles and RGC soma loss.

M., Morini, F., Mediavilla, T., Nilsson, E., Oradd, G., Hahn, M., Chotiwan, N., Visa Majoral, M., Berggren, P.-O., Ilegems, E., Overby, A. K., Ahlgren, U., Marcellino, D. Abstract: Optical projection tomography (OPT) and light sheet fluorescence microscopy (LSFM) are high resolution optical imaging techniques operating in the mm-cm range, ideally suited for ex vivo 3D whole mouse brain imaging. Although these techniques exhibit high sensitivity and specificity for antibody labeled targets, the provided anatomical information remains limited. To allow anatomical mapping of fluorescent signal in whole brain, we developed a novel magnetic resonance (MR) based template with its associated tissue priors and atlas labels, specifically designed for brains subjected to tissue processing protocols required for 3D optical imaging. We investigated the effect of tissue preprocessing and clearing on brain size and morphology and developed optimized templates for BABB/Murrays clear (OCUM) and DBE/iDISCO (iOCUM) cleared brains. By creating optical (i)OCUM fusion images using our mapping procedure, we localized dopamine transporter and translocator protein expression and tracer innervation from the eye to the lateral geniculate nucleus of thalamus and superior colliculus. These fusion images allowed for precise anatomical identification of fluorescent signal in discrete brain areas. As such, these templates enable applications in a broad range of research areas integrating optical 3D brain imaging by providing an MR template for cleared brains.

Abstract: Morphometric studies have provided crucial insights into the skull anatomy of commonly used wildtype (WT) laboratory mice strains such as the C57BL/6. With the increasing use of transgenic (TG) animals in neuroscience research, it is important to determine whether the results from morphometric studies performed on WT strains can be extended to TG strains derived from these WT strains. We report a new computer vision-based analysis pipeline for surveying mouse skull morphology using microcomputed tomography (micro-CT) scans. We applied this pipeline to study and compare eight cohorts of adult mice from two strains, including both male and female mice at two age points. We found that the overall skull morphology was generally conserved between cohorts, with only 13% of landmark distance differences reaching statistical significance. In addition, we surveyed the dorsal skull bone thickness differences between cohorts. We observed significantly thicker dorsal, parietal, and/or interparietal bones in WT, male, or older mice for 53% of thickness comparisons. This knowledge of dorsal skull bone thickness has potential implications for surgical planning through skull imaging and has applications in automating cranial microsurgeries on mice.

Constraining the Fluctuating Gunn-Peterson Approximation Using Lyman- α Forest Tomography at z=2 by Robin Kooistra et al. on Thursday 22 September The fluctuating Gunn-Peterson approximation (FGPA) is a commonly-used method to generate mock Lyman-$alpha$ (Ly$alpha$) forest absorption skewers at Cosmic Noon ($zgtrsim 2$) from the matter-density field of $N$-body simulations without running expensive hydrodynamical simulations. Motivated by recent developments in 3D IGM tomography observations as well as matter density field reconstruction techniques applied to galaxy redshift samples at $zsim 2$, we examine the possibility of observationally testing FGPA by directly examining the relationship between the Ly$alpha$ transmission and the underlying matter density field. Specifically, we analyze the EAGLE, Illustris, IllustrisTNG and Nyx cosmological hydrodynamic simulations, that were run with different codes and sub-grid models. While the FGPA is an excellent description of the IGM in lower-density regions, the slope of the transmission-density distribution at higher densities is significantly affected by feedback processes causing the FGPA to break down in that regime. Even without added feedback, we find significant deviations caused by hydrodynamical effects arising from non-linear structure growth. We then proceed to make comparisons using realistic mock data assuming the sightline sampling and spectral properties of the recent CLAMATO survey, and find that it would be challenging to discern between the FGPA and hydrodynamical models with current data sets. However, the improved sightline sampling from future extremely large telescopes or large volumes from multiplexed spectroscopic surveys such as Subaru PFS should allow for stringent tests of the FGPA, and make it possible to detect the effect of galaxy feedback on the IGM. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2201.10169v2

Commentary by Dr. Hiromasa Otake

This is the fourth episode of a 7-part series on presbyopia correction at the time of cataract surgery.  This podcast series forms part of a GENEYE digital course that has been developed by Dr Jacqueline Beltz for Advanced Ophthalmology Trainees in Victoria, Australia.  The full course is available at geneye.org.au under online training.  So far, we've covered IOL options, patient selection and optimisation, and astigmatism correction and refractive targets.  There's a lot to consider, especially when trifocal or EDOF IOLs that utilise diffractive technologies are planned.  Corneal tomography has come up as an important topic in every episode so far.  One of the reasons why it's important to know the status of the cornea is to consider the impact of higher order aberrations when combined with diffractive IOL technologies.  Patients with aberrated corneas can be highly symptomatic of positive dysphotopsias such as glare and haloes after trifocal IOLs, so it's best to consider other options such as monofocal IOLs, small aperture IOLs or maybe even negative spherical aberration EDOFs in those cases.Should we or should we not ALWAYS do tomography when we're considering trifocal IOLs?  In this episode Dr Jacqueline Beltz is joined by Associate Professor Elaine Chong to answer this question and to discuss corneal tomography in this setting.  Elaine is a cataract, cornea and refractive surgeon in Melbourne.  She is director of ophthalmology at Royal Melbourne Hospital and also part of the Corneal Unit at The Eye and Ear Hospital.  Prior to these positions, Elaine underwent double subspecialty fellowship training - first in medical retina and later in cornea and refractive surgery.  It was at Singapore National Eye Centre that Elaine completed her corneal training.   Please subscribe to this podcast and remember that the full digital course is available at geneye.org.au

In this episode, Dr. Joel Schuman gives a detailed overview of how a team of collaborators from diverse academic backgrounds developed Optical Coherence Tomography (OCT), a technology that was a leap forward in the field of Ophthalmology. Dr. Schuman further explores how curiosity lies at the center of his motivation to continue discovering and innovating even after co-developing a breakthrough medical technology. 

In this podcast, John Samples, MD, and Brian Francis, MD, discuss the current and evolving role of optical coherence tomography angiography in the management of glaucoma.

Dr. Nick West is the Chief Medical Officer and DVP Global Medical Affairs for Vascular at Abbott.  With the launch of the Ultreon software 1.0, Abbott is bringing a new level of analysis to their Optical Coherence Tomography intracoronary imaging tool. Nick explains, "And the idea of this software package is, on top of this best-in-class in terms of resolution imaging technology to help physicians, the Ultreon software augments physician decision-making to effectively enable them to do a better job, but more easily."  "Optical Coherence Tomography already existed. A very powerful tool, as I said. A very high degree of precision and accuracy in measurement. However, one of the issues with OCT is that, as well as understanding how to actually physically use the catheter, which is reasonably straightforward, it's very similar to other devices that interventional cardiologists use, but they then have to learn to interpret the images you get out. So acquiring the pictures is relatively straightforward, but then how do you interpret these detailed pictures?" "You still need to know how to use the catheter, but the Ultreon 1.0 software uses machine learning algorithms. That's artificial intelligence, if you like, where we've taught the software over hundreds and hundreds of different OCT pictures. We taught it - what is calcification? What is that hardened narrowing?

Dr. Kelly Diehl interviews Dr. Laura Selmic, Associate Professor in Surgical Oncology at The Ohio State University College of Veterinary Medicine, about her Foundation-funded work to evaluate a new diagnostic tool for use in treating feline injection-site sarcomas. Selmic's team investigated the use of optical coherence tomography in detecting cancer cells left behind following removal of injection-site sarcomas in client-owned cats undergoing surgery.

Ideon Technologies CEO Gary Agnew joined Steve Darling from Proactive to share details about news technology that was born out of the TRIUMF, Canada's national particle accelerator, laboratory. Agnew telling Proactive the science behind the artificial intelligence that provides x-ray-like visibility up to 1 km beneath the Earth's surface. It then detects subsurface muons and transforming the data into reliable geophysical surveys and 3D density maps. Agnew also told Proactive, the technology can identify and image anomalies such as mineral and metal deposits, air voids, caves, and other structures.
