A family of snakes comprising four subfamilies: Azemiopinae (the mountain viper, the sole member of this subfamily), Viperinae (true vipers), Crotalinae (pit vipers) and Causinae. They are widespread throughout the world, being found in the United States, Central and South America, Europe, Asia and Africa. Their venoms act on the blood (hemotoxic) as compared to the venom of elapids which act on the nervous system (neurotoxic). (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, pp333-36) . 0.46

Prasterone, 3 alpha-Isomer . 5 Androsten 3 beta hydroxy 17 one . 5 Androsten 3 ol 17 one . Prasterone, 3 alpha Isomer . Dehydroisoandrosterone . Prasterone . A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion. . 0.45

Receptor, Polyaromatic Hydrocarbon . Receptor, TCDD . Aryl Hydrocarbon Receptors . AH Receptors . Dioxin Receptors . Receptors, AH . Receptors, Dioxin . TCDD Receptors . Cytoplasmic proteins that bind certain aryl hydrocarbons, translocate to the nucleus, and activate transcription of particular DNA segments. AH receptors are identified by their high-affinity binding to several carcinogenic or teratogenic environmental chemicals including polycyclic aromatic hydrocarbons found in cigarette smoke and smog, heterocyclic amines found in cooked foods, and halogenated hydrocarbons including dioxins and polychlorinated biphenyls. No endogenous ligand has been identified, but an unknown natural messenger with a role in cell differentiation and development is suspected. . 0.45
