    Calcium Imaging of Neuronal Activity under Gradually Changing Odor Stimulation in Caenorhabditis elegans
    Authors:  Yuki Tanimoto and Koutarou D. Kimura, date: 01/05/2021, view: 337, Q&A: 0
    [Abstract]

    Olfactory behavior is among the most fundamental animal behaviors both in the wild and in the laboratory. To elucidate the neural mechanisms underlying olfactory behavior, it is critical to measure neural responses to odorant concentration changes resembling those that animals actually sense during olfactory behavior. However, reproducing the

    A Parkinson’s Disease-relevant Mitochondrial and Neuronal Morphology High-throughput Screening Assay in LUHMES Cells
    [Abstract]

    Parkinson’s disease is a devastating neurodegenerative disorder affecting 2-3% of the population over 65 years of age. There is currently no disease-modifying treatment. One of the predominant pathological features of Parkinson’s disease is mitochondrial dysfunction, and much work has aimed to identify therapeutic compounds which can

    Live-cell Imaging and Quantitative Analysis of Meiotic Divisions in Caenorhabditis elegans Males
    Authors:  Gunar Fabig, Falko Löffler, Christian Götze and Thomas Müller-Reichert, date: 10/20/2020, view: 579, Q&A: 0
    [Abstract] Live-imaging of meiotic cell division has been performed in extracted spermatocytes of a number of species using phase-contrast microscopy. For the nematode Caenorhabditis elegans, removal of spermatocytes from gonads has damaging effects, as most of the extracted spermatocytes show a high variability in the timing of meiotic divisions or ...
    Real-time Three-dimensional Tracking of Endocytic Vesicles
    Authors:  Stephanie Duhamel and Kossay Zaoui, date: 10/20/2020, view: 728, Q&A: 0
    [Abstract] Endocytic trafficking and recycling are fundamental cellular processes that control essential functions such as signaling protein complexes transport and membrane identity. The small GTPase Rabs are indispensable component of the endosomal recycling machinery. The Rabs bind to effectors to mediate their functions, such as protein sorting and ...
    Simple Time-lapse Imaging for Quantifying the Hydrostatic Production of Oxygenic Photogranules
    Authors:  Esmee D. Joosten, Jérôme Hamelin and Kim Milferstedt, date: 10/05/2020, view: 614, Q&A: 0
    [Abstract] Oxygenic photogranules (OPGs) are dense, three-dimensional aggregates containing a syntrophic, light-driven microbial community. Their temporal and spatial development interests microbial ecologists working at the bioprocess engineering interface, as this knowledge can be used to optimize biotechnological applications, such as wastewater treatment ...
    Live-cell Imaging by Super-resolution Confocal Live Imaging Microscopy (SCLIM): Simultaneous Three-color and Four-dimensional Live Cell Imaging with High Space and Time Resolution
    Authors:  Kazuo Kurokawa and Akihiko Nakano, date: 09/05/2020, view: 1936, Q&A: 0
    [Abstract] Many questions in cell biology can be solved by state-of-the-art technology of live cell imaging. One good example is the mechanism of membrane traffic, in which small membrane carriers are rapidly moving around in the cytoplasm to deliver cargo proteins between organelles. For directly visualizing the events in membrane trafficking system, ...
    Extracellular Vesicles Tracking and Quantification Using CT and Optical Imaging in Rats
    [Abstract] Exosomes, a subtype of extracellular vesicles, are nanovesicles of endocytic origin. Exosomes contain a plethora of proteins, lipids, and genetic materials of parent cells to facilitate intercellular communications. Tracking exosomes in vivo is fundamentally important to understand their biodistribution pattern and the mechanism of ...
    Single Cell Migration Assay Using Human Breast Cancer MDA-MB-231 Cell Line
    Authors:  David M. Gau and Partha Roy, date: 04/20/2020, view: 2394, Q&A: 0
    [Abstract] Cell migration is a fundamental cellular process that plays a crucial role in many physioglogical and pathological processes such as wound healing or cancer metastasis. Many assays have been developed to examine cell migration, such as the wound healing or scratch assay, Boyden Chamber or transwell assay, and the method we will describe here, ...
    Quantification of Mitochondrial Dynamics in Fission Yeast
    Authors:  Leeba Ann Chacko and Vaishnavi Ananthanarayanan, date: 12/05/2019, view: 1728, Q&A: 0
    [Abstract] Mitochondria are double-membraned organelles responsible for several functions in the cell including energy production, calcium signaling, and cellular metabolism. An equilibrium between fission and fusion events of mitochondria is required for their proper functioning. Mitochondrial morphologies have been quantified in yeast using image ...
    Mapping the Mechanome–A Protocol for Simultaneous Live Imaging and Quantitative Analysis of Cell Mechanoadaptation and Ingression
    [Abstract] Mechanomics, the mechanics equivalent of genomics, is a burgeoning field studying mechanical modulation of stem cell behavior and lineage commitment. Analogous to mechanical testing of a living material as it adapts and evolves, mapping of the mechanome necessitates the development of new protocols to assess changes in structure and function in ...
