Metastasis is the spread of cancer cells to new areas of the body (often by way of the lymph system or bloodstream). A metastatic cancer, or metastatic tumor, is one which has spread from the primary site of origin (where it started) into different area(s) of the body. Tumors formed from cells that have spread are called secondary tumors.
Acetylcholinesterase inhibition. An acetylcholinesterase inhibitor (often abbreviated AChEI) or anti-cholinesterase is a chemical or a drug that inhibits the acetylcholinesterase enzyme from breaking down acetylcholine, thereby increasing both the level and duration of action of the neurotransmitter acetylcholine.ome major effects of cholinesterase inhibitors: 1  Actions on the parasympathetic nervous system, (the parasympathetic branch of the autonomic nervous system) may cause bradycardia, hypotension, hypersecretion, bronchoconstriction, GI tract hypermotility, and decrease intraocular pressure.
Amylase inhibitors contain substances that prevent dietary carbohydrates from being absorbed by the body and may aid in weight loss. Amylase inhibitors are also known as starch blockers because they contain substances that prevent dietary starches from being absorbed by the body. Starches are complex carbohydrates that cannot be absorbed unless they are first broken down by the digestive enzyme amylase and other, secondary, enzymes. When starch blockers were first developed years ago, they were found not to be potent enough to prevent the absorption of a significant amount of carbohydrate.
