3,3′-Diaminobenzidine (DAB) is an organic compound with the formula (C 6 H 3 (NH 2) 2) 2. This derivative of benzidine is a precursor to polybenzimidazole, which forms fibers that are renowned for their chemical and thermal stability. [1] As its water-soluble tetrahydrochloride, DAB has been used in immunohistochemical staining of nucleic ...
Sunflower sea star regenerates its arms. Dwarf yellow-headed gecko with regenerating tail. Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage.

Granzyme B is released with perforin which inserts into a target cell's plasma membrane forming a pore.Perforin has a radius of 5.5 nm and granzyme B has a stokes radius of 2.5 nm and can therefore pass through the perforin pore into the target to be destroyed.
GDF11 fed mice saw 45.7% reduction in senescent liver cells and a 21.7% reduction in senescent kidney cells. GDF11 induces generation of antioxidant enzymes (CAT, SOD and GPX), which directly results in reduction of ROS levels, which then decelerates protein oxidation, lipid peroxidation and possibly LF and SA-β-Gal development, which in turn ...
The kind of intelligence that makes this possible is a little different from how we imagine human intelligence, says Andy Dobson, Ph.D., professor of ecology and evolutionary biology at Princeton ...
Monocytes form two groups: a circulating group and a marginal group that remain in other tissues (approximately 70% are in the marginal group). Most monocytes leave the blood stream after 20–40 hours to travel to tissues and organs and in doing so transform into macrophages [ 70 ] or dendritic cells depending on the signals they receive.

It helps to imagine food as a spectrum: At one end, you have nutrient-dense, anti-inflammatory foods (think: colorful vegetables, berries, high-quality olive oil, fatty fish, nuts, seeds, and ...
"Try to see the good in people." "Come on − he can't be that bad." "You should be grateful to even be in a relationship." If you've heard these phrases before, chances are you've been bright sided.
