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 ...
[2] [3] [5] LT-αβ, which is produced by activated TH1, CD8+ T cells, and natural killer (NK) cells, is known to have a major role in the normal development of Peyer's patches. [6] [7] Studies have found that mice with an inactivated LT-α gene (LTA) lack developed Peyer's patches and lymph nodes. In addition, LT-αβ is necessary for the ...
Principle of tissue engineering. Researchers are able to take the tissue from a donor or cadaver, lyse and kill the cells within the tissue without damaging the extracellular components, and finish with a product that is the natural ECM scaffold that has the same physical and biochemical functions of the natural tissue.

There are a certain amount of immune cells naturally circulating through your body at all times. But when you exercise, and increase your blood flow, you help push more immune cells from your ...
In contrast, immunohistochemical samples are sections of biological tissue, where each cell is surrounded by tissue architecture and other cells normally found in the intact tissue. Immunocytochemistry is a technique used to assess the presence of a specific protein or antigen in cells (cultured cells, cell suspensions) by use of a specific ...
Seed oils, including peanut oil and sunflower oil, have been in the news a lot recently. Dietitians explain if seed oils are healthy, and health risks of them.
In humans with non-injured tissues, the tissue naturally regenerates over time; by default, new available cells replace expended cells. For example, the body regenerates a full bone within ten years, while non-injured skin tissue is regenerated within two weeks. [2] With injured tissue, the body usually has a different response.
Two new studies suggest once again the importance of getting a good night's sleep for good health over a lifetime, as scientists pursue new understandings of restorative deep sleep.
