History of diabetes further clarified in 1921, when Sir Frederick Grant Banting and Charles Herbert Best repeated the work of Von Mering and Minkowski, and went further to demonstrate they could reverse induced diabetes in dogs by giving them an extract from the pancreatic islets of Langerhans of healthy dogs. The islets of Langerhans was discovered in 1869 by an anatomist named Paul Langerhans. He identified the keys cells in the pancreas which produce the main substance that controls glucose levels in the body. Banting, Best, and colleagues (especially the chemist Collip) went on to purify the hormone insulin from bovine pancreases at
Eccrine sweat gland sweat than normal. Similarly, cystic fibrosis patients also produce salty sweat. But in these cases, the problem is in the CFTR chloride transporter that is also located on the apical membrane of eccrine gland ducts. Dermcidin is a newly isolated antimicrobial peptide produced by the eccrine sweat glands. Eccrine sweat gland Eccrine glands (; from "ekkrinein" "secrete"; sometimes called merocrine glands) are the major sweat glands of the human body, found in virtually all skin, with the highest density in palm and soles, then on the head, but much less on the trunk and the extremities. In other mammals, they
