The integration of a novel high spatiotemporal resolution volume imaging technique and a fast 3D tracking system allows capturing whole brain neural activities in a freely behaving larval zebrafish.
In contrast to previous post-mortem or fixed tissue histochemical reports, live calcium and mitochondrial imaging data suggest that the enteric nervous system is not generally affected in Parkinson's disease patients.
Establishment of two-photon imaging with a 1100-nm laser, which underfills the objective's back aperture, detects activity of multiple neurons in the prelimbic area and hippocampal CA1 region of the intact mouse brain.
A series of quantitative behavioural and opto-physiological analyses using a novel robot microscope system reveals that C. elegans computes the time-differential and time-integral of sensory information for decision-making during olfactory navigation.
Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.
Cyanine fluorophores are encoded as non-canonical amino acids to produce functional proteins in cell-free translation systems and live cells for single-molecule imaging.
A comprehensive mapping of the proteome and transcriptome during the complete replicative lifespan of budding yeast predicted an increased abundance of the protein biogenesis machinery is most causal for aging.
Aging is a process characterized by gradual metabolome remodeling, deceleration of the remodeling in late life and under conditions that extend lifespan, and a mortality-associated pattern of cumulative damage.
A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.
