kovy vzácných zemin

A group of elements that include SCANDIUM; YTTRIUM; and the LANTHANOID SERIES ELEMENTS. Historically, the rare earth metals got their name from the fact that they were never found in their pure elemental form, but as an oxide. In addition they were very difficult to purify. They are not truly rare and comprise about 25% of the metals in the earth`s crust.

Mitotic Metaphase

Metaphase occurring as part of mitosis. Metaphase is the part of nuclear division in which, canonically, chromosomes become aligned on the equatorial plate of the cell. Mitosis is the cell cycle process in which, canonically, the nucleus of a eukaryotic cell divides to produce two daughter nuclei whose chromosome complement is identical to that of the mother cell. [ISBN:0815316194]

Metaproterenol Sulfate

The sulfate salt form of metaproterenol, a short-acting and selective sympathomimetic beta-receptor agonist with bronchodilator activity. Metaproterenol sulfate binds beta-2 adrenergic receptors in bronchial smooth muscle and stimulates intracellular adenyl cyclase, thereby increasing the production of cyclic adenosine monophosphate (cAMP). Increased cAMP levels cause relaxation of bronchial smooth muscle, improve mucocliary clearance and reduce inflammatory cell mediator release, especially from mast cells.

metformin

A biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. (From Martindale, The Extra Pharmacopoeia, 30th ed, p289)
MSH

A biguanide with antihyperglycemic activity. Metformin exerts its action by improving hepatic sensitivity to insulin, thereby suppressing hepatic glucose production and increasing hepatic glycogen stores. In addition, metformin increases the number and/or affinity of insulin receptors on cell surface membranes in muscle and adipose tissue, thereby increasing the sensitivity to insulin at receptor and post-receptor binding sites and increasing glucose uptake peripherally.
