But if you ask a student to find the number of degrees between the hands of a clock at 4:08, then this is more interesting math problem. What if you pose the problem in this way: Find the number of degrees between the hands of a clock at 4:08.
Protamine sulfate is a drug that reverses the anticoagulant effects of heparin by binding to it.Protamine was originally isolated from the sperm of salmon and other species of fish but is now produced primarily through recombinant biotechnology.It is a highly cationic peptide that binds to either heparin or low molecular weight heparin (LMWH) to form a stable ion pair, which does not have anticoagulant activity.rotamine was originally isolated from the sperm of salmon and other species of fish but is now produced primarily through recombinant biotechnology.
By Sally Robertson, BSc. Histamine is a biologically active substance that plays a key role in the bodyâs inflammatory reaction to injury caused by infection, physical damage or allergy. Histamine is widely distributed throughout the animal kingdom and is also present in insect venom, many plants and bacteria.he increased permeability of blood vessels allows immune cells and substances to migrate from the bloodstream, through the vessels and into the site where injury or infection has occurred. Leukocytes and blood plasma proteins can then begin the process of fighting infection and healing the tissue.
