Impact of Photobleaching on Quantitative, Spatio-Temporal, Super-Resolution Imaging of Mitochondria in Live C. elegans Larvae

Academic Background and Problem Statement Mitochondria, as crucial organelles in eukaryotic cells, are involved in cellular energy metabolism, signal transduction, and the regulation of cell survival and death. Mitochondrial dysfunction is associated with various human diseases, including neurodegenerative disorders, cardiovascular diseases, diabet...

Rapid Full-Color Serial Sectioning Tomography with Speckle Illumination and Ultraviolet Excitation

Rapid Full-Color Serial Sectioning Tomography with Speckle Illumination and Ultraviolet Excitation

Academic Background Three-dimensional (3D) high-resolution large-volume imaging has remained a significant challenge in the field of biomedical research. Traditional two-dimensional (2D) slice imaging, while capable of providing planar morphological information of tissues and cells, fails to comprehensively display internal 3D structural informatio...

Uranium-Free Imaging of Tissue Architectures in Low Vacuum Scanning Electron Microscopy

Uranium-Free KMnO₄/Pb Staining Enables Imaging of Tissue Architectures in Low Vacuum Scanning Electron Microscopy Academic Background Electron Microscopy (EM) is one of the most powerful tools for studying the ultrastructure of cells and tissues. However, traditional metal staining methods for biological samples often require the use of harmful ura...

Nucleosome Fibre Topology Guides Transcription Factor Binding to Enhancers

Nucleosome Fibre Topology Guides Transcription Factor Binding to Enhancers Academic Background The establishment of cellular identity relies on the concerted action of multiple transcription factors (TFs) bound to enhancers of cell-type-specific genes. Although TFs recognize specific DNA motifs within accessible chromatin, this information alone is...

Lithocholic Acid Phenocopies Anti-Ageing Effects of Calorie Restriction

Lithocholic Acid Phenocopies Anti-Ageing Effects of Caloric Restriction Academic Background Caloric restriction (CR) is a dietary intervention used to promote health and longevity by reducing food intake. Although CR has been shown to extend the lifespan of various organisms, the specific metabolic mechanisms behind its effects remain unclear. In p...
