Stroke Causes

Stroke is a serious medical emergency caused by a depleted supply of blood to a part of the brain. There are two types of stroke - ischemic stroke and hemorrhagic stroke.

Safety of Statins

Statins (also known as 3-hydroxy-3-methylgutaryl coenzyme A reductase inhibitors) are widely prescribed cholesterol-lowering drugs for the treatment of dyslipidemia and cardiovascular disease. Although they are considered to be drugs with a very good safety profile, there are many concerns that their adverse effects might compromise their proven beneficial effects due to their extensive usage.

Statin Drugs

The inhibitors of 3-hydroxy-3-methylglutaryl-CoA reductase (or statins) are the mainstay of therapy for hyperlipidemia.

11 Dec 2009

Statin Uses

Statins are a class of drugs used to lower cholesterol levels that were initially identified in the early 1970's from Penicillium and Aspergillus fungi. All statins competitively inhibit 3-hydroxy-3-methylglutaryl coenzyme (HMG-CoA) reductase, the principal rate-limiting enzyme that controls the conversion of HMG-CoA to mevalonic acid.

Statin History

Statins are recommended as a first-line therapy for the management of lipid disorders.

11 Dec 2009

What are Statins?

Statins represent a class of cholesterol-lowering agents used for the treatment of dyslipidemia (abnormal amount of lipids) and the reduction of atherosclerotic cardiovascular disease risk. Their broad and potent effects on the lipid profile and cholesterol-independent pleiotropic cardioprotective effects positioned them among the most prescribed medications worldwide.

Non-Motile Sperm Cells

A sperm is the male reproductive cell. When the sperm has the usual single flagellum (or "tail") to propel it along, it is called a spermatozoon and may be described as uniflagellate. Unlike this motile cell, a sperm that lacks a flagellum is not motile and is termed a spermatium.

Motile Sperm Cells

The full name for a sperm that has a single flagellum (or "tail") to propel it along is a spermatozoon.

Sperm - Male Reproductive Cells

Sperm is the male reproductive cell in vertebrates. The term is derived from the Greek word "sperma" meaning "seed". Sperm were first observed under a microscope in 1677 by Antonie van Leeuwenhoek who described them as little animals or animalcules.

Drugs Targeting the 5-HT System

Serotonin or 5-hydroxytryptamine (5-HT) is a neurotransmitter that binds to 5-HT receptors in the central and peripheral nervous systems. Serotonin is an example of an inhibitory neurotransmitter that has general sedative effects on the brain and counteracts the effects of stimulants such as caffeine, for example.

Serotonin Function

Serotonin is an important neurotransmitter in the function of the central nervous system and the gastrointestinal tract in both non-vertebrates and vertebrates.

11 Dec 2009

What is Serotonin?

Serotonin is an example of a neurotransmitter, a chemical messenger that is passed between nerve cells. When a nerve impulse reaches the axon at the end of a nerve, neurotransmitters are released which cross an area called the synapse to be received by a specific receptor on the end of a target nerve. Once received by the target nerve, the neurotransmitter may either excite that nerve to fire its own signal or prevent it from firing the signal.
