Fatty acid desaturaseFatty acid desaturases (also called unsaturases) are a family of enzymes that convert saturated fatty acids into unsaturated fatty acids and polyunsaturated fatty acids. For the common fatty acids of the C18 variety, desaturases convert stearic acid into oleic acid. Other desaturases convert oleic acid into linolenic acid, which is the precursor to alpha-linolenic acid, gamma-linolenic acid, and eicosatrienoic acid. Two subgroups of desaturases are recognized: Delta - indicating that the double bond is created at a fixed position from the carboxyl end of a fatty acid chain.
HypoglycemiaHypoglycemia, also called low blood sugar, is a fall in blood sugar to levels below normal, typically below 70 mg/dL (3.9 mmol/L). Whipple's triad is used to properly identify hypoglycemic episodes. It is defined as blood glucose below 70 mg/dL (3.9 mmol/L), symptoms associated with hypoglycemia, and resolution of symptoms when blood sugar returns to normal. Hypoglycemia may result in headache, tiredness, clumsiness, trouble talking, confusion, fast heart rate, sweating, shakiness, nervousness, hunger, loss of consciousness, seizures, or death.
AmiodaroneAmiodarone is an antiarrhythmic medication used to treat and prevent a number of types of cardiac dysrhythmias. This includes ventricular tachycardia (VT), ventricular fibrillation (VF), and wide complex tachycardia, as well as atrial fibrillation and paroxysmal supraventricular tachycardia. Evidence in cardiac arrest, however, is poor. It can be given by mouth, intravenously, or intraosseously. When used by mouth, it can take a few weeks for effects to begin. Common side effects include feeling tired, tremor, nausea, and constipation.
Enterohepatic circulationEnterohepatic circulation refers to the circulation of biliary acids, bilirubin, drugs or other substances from the liver to the bile, followed by entry into the small intestine, absorption by the enterocyte and transport back to the liver. Enterohepatic circulation is an especially important concept in the field of toxicology as many lipophilic xenobiotics undergo this process causing repeated liver damage. Hepatocytes metabolize cholesterol to cholic acid and chenodeoxycholic acid.
Right to housingThe right to housing (occasionally right to shelter) is the economic, social and cultural right to adequate housing and shelter. It is recognized in some national constitutions and in the Universal Declaration of Human Rights and International Covenant on Economic, Social and Cultural Rights. The right to housing is regarded as a freestanding right in the International human rights law which was clearly in the 1991 General Comment on Adequate Housing by the UN Committee on Economic, Social and Cultural Rights.
