(Tıp) Birbirine yapışık 4 zincirden ibaret cisimler olup, 3 zincirin herbiri 6 ve 4 üncü zincirde 5 karbon atomunu ihtiva eder (Siklopentanofenantren halkası)
A class of organic compounds having a structure of 17 carbon atoms arranged in four rings; they are lipids, and occur naturally as sterols, bile acids, adrenal and sex hormones, and some vitamins; many drugs are synthetic steroids
in bone marrow transplantation, a drug commonly used in combination with other drugs to prevent and control graft-versus-host disease
A molecule related to cholesterol Many important hormones such as estrogen and testosterone are steroids See hormone
-a large family of chemical substances which includes hormones and drugs that have a chemical structure comprised of a few rings attached to each other Most steroids contain twenty-seven or more carbon atoms
a natural occuring compound (fat-soluble and having a 17-cargon-atom ring as a basis), including many hormones and vitamin precursors
any of several fat-soluble organic compounds having as a basis 17 carbon atoms in four rings; many have important physiological effects
a family of substances that share a similar chemical structure, including certain hormones (e g , testosterone) and various drugs Some steroid drugs are used to lessen inflammatory reactions
A plant or animal lipid having the characteristic tetracyclic ring structure of the steroid nucleus, namely three six-membered rings and one five-membered ring
the factor (always less than one) that reflects the fraction of collisions with orientations that can produce a chemical reaction
{i} any of a number of fat-soluble organic compounds (including sterols, bile acids, etc.)
A large class of pharmaceutical agents that chemically resemble cholesterol Two better known types are anabolic steroids often used in athletics, and glucocorticoid steroids that are used to reduce inflammation
A type of hormone Steroids are often given to patients along with one or more anticancer drugs and appear to help to control the effects of the disease on the body
A large class of pharmaceutical agents that chemically resemble cholesterol Two better known types are anabolic steroids as used illegally in athletics, and glucocorticoid steroids which are used to reduce inflammation This latter drug type is used in PRK to regulate regression and reduce post PRK inflammatory haze
A steroid is a type of chemical substance found in your body. Steroids can be artificially introduced into the bodies of athletes to improve their strength. Any of a class of natural or synthetic organic compounds with a molecular core, or nucleus, of 17 carbon atoms in a characteristic three-dimensional arrangement of four rings. The configuration of the nucleus, the nature of the groups attached to it, and their positions distinguish different steroids. Hundreds have been found in plants and animals and thousands more synthesized or made by modifying natural steroids. Steroids are important in biology, chemistry, and medicine. Examples include many hormones (including the sex hormones), bile acids, sterols (including cholesterol), and oral contraceptives (see contraception). Digitalis was the first steroid widely used in Western medicine. Corticosteroids (see cortisone) and their synthetic analogs are used to treat rheumatism and other inflammatory ailments. See also anabolic steroid
A large family of chemical substances, comprising many hormones, vitamins, body constituents, and drugs, each containing the tetracyclic cyclopenta[alpha]phenanthrene skeleton
Any of several steroids, synthesized in the myelinating glial cells, which alter neuronal excitability through interaction with neurotransmitter-gated ion channels
Anabolic steroids are drugs which people, especially athletes, take to make their muscles bigger and to give them more strength. A group of synthetic hormones that promote the storage of protein and the growth of tissue, sometimes used by athletes to increase muscle size and strength. a drug that makes muscles grow quickly, sometimes used illegally by people in sport (anabolic 1800-1900 From ana- (from , from , ) + metabolic). Steroid hormone that increases tissue growth. Anabolic steriods are given to elderly or postoperative patients to promote muscle growth and tissue regeneration. Unsupervised use by athletes to build muscle and improve strength can have serious harmful effects, including coronary heart disease, sexual and reproductive disorders, immunodeficiencies, liver damage, stunted growth, aggressive behaviour, susceptibility to connective-tissue injury, and (in females) irreversible masculinization
any of a group of synthetic steroid hormones used to stimulate muscle and bone growth; more than 100 have been developed and each requires a prescription to be used legally in the United States; sometimes used illicitly by athletes to increase their strength
A general term for a wide variety of chemicals, natural and synthetic In the context of asthma, "steroids" is usually a shorthand way of referring to corticosteroid medicines (taken to reduce asthma inflammation) Other steroids, including natural and synthetic sex hormones (such as the testosterone-like compounds sometimes used by athletes to build their muscles), are generally unrelated to asthma
Anabolic steroids are testosterone or testosterone-like drugs that produce anabolic activity (greater muscular bulk) by increasing protein production and androgenic activity (enhanced secondary sexual characteristics) such as hair growth in the male Injectable forms are known as "oils" or "waters" Oils refer to the long-acting types Waters are short-acting forms
With concerns to lupus, Steroids usually is short for corticosteroids They are not to be confused with anabolic steroids--which athletes sometimes take to build muscle
Any of a group of compounds (e g , sex hormones) having the carbon atom ring structure of the steroids A steroid is any of a group of solid, cyclic unsaturated alcohols, such as cholesterol, found in plant and animal tissue
(Also called "Anabolic Steroids") Prescription drugs derived from growth-stimulating male testosterone Though long taken by some professional and amateur body builders -- and other athletes -- to increase muscle size and endurance, there are side effects (including liver and heart damage, and mental problems) associated with the use of some steroids While certain steroids are available for use in the U S , others are banned
