Cellular ‘brakes’ may gradual memory process in aging brains University of Florida experts may have discovered why some human brain cells necessary for healthy memory may survive later years or disease, while similar cells a hairsbreadth apart die hardly. The discovery, released online ahead of print in the type publication Cell Loss of life & Differentiation, could help scientists understand and find solutions for age-related memory space loss.

Cells close to death from toxin publicity may survive when toxins are removed Almost all cells that look like on a one-way track to death after contact with toxins can bounce back again completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, in the June 15 issue of Molecular Biology of the Cell published, isn’t only a testament to the indomitable cellular spirit, but may possibly also offer some practical insight on how to save dying tissues after heart episodes or strokes as well as prevent cancers in cells transiently exposed to toxins. For decades, researchers have got known that cells undergo a type of programmed death called apoptosis, says study innovator Denise Montell, Ph.D., a professor in the Section of Biological Chemistry at the Johns Hopkins University School of Medicine.
