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 ...
Studies show that keeping your head at the appropriate height—about 2 inches (or 5 centimeters) off the bed—helps air flow into the lungs and stabilizes your respiratory function. However ...
The bubbles which are small enough to pass through the lung capillaries may be small enough to be dissolved due to a combination of surface tension and diffusion to a lowered concentration in the surrounding blood, though the Varying Permeability Model nucleation theory implies that most bubbles passing through the pulmonary circulation will ...

Temperature influences the body’s circadian rhythm, which regulates sleep-wake cycles, says Dr. Vendrame. In other words, your body’s temperature tells you when to sleep and when to be awake.
