androgen analog definition: steroidal compounds related to testosterone.
Cosyntropin definition: A synthetic peptide that is identical to the 24-amino acid segment at the N-terminal of ADRENOCORTICOTROPIC HORMONE. ACTH (1-24), a segment similar in all species, contains the biological activity that stimulates production of CORTICOSTEROIDS in the ADRENAL CORTEX.
Cosyntropin definition: A synthetically-derived subunit of the endogenous peptide pituitary hormone adrenocorticotropic hormone (ACTH). Consisting of the first 24 amino acids from the amino terminal of ACTH, Cortrosyn is usually prepared for injection and intended for diagnostic and not therapeutic use. Similar to endogenous ACTH, this agent stimulates the adrenal secretion of specific adrenal steroids that can be measured in the plasma. (NCI04)
estrogen analog definition: synthetic or natural chemical compounds which resemble naturally occurring estrogens in structure and/or function.
Estrogens, Synthetic definition: Compounds obtained by chemical synthesis which possess estrogenic activity, but differ in structure from naturally occurring estrogens.
Genes, Synthetic definition: Biologically functional sequences of DNA chemically synthesized in vitro.
progestin definition: class of drugs which mimic progesterone by promoting gestation.
Progestins definition: Compounds that interact with PROGESTERONE RECEPTORS in target tissues to bring about the effects similar to those of PROGESTERONE. Primary actions of progestins, including natural and synthetic steroids, are on the UTERUS and the MAMMARY GLAND in preparation for and in maintenance of PREGNANCY.
Progestagen definition: Substances that produce effects similar to those of progesterone, the only natural progestagen. All other progestogens are synthetic and are often referred to as progestins. All progestagens have antiestrogenic and antigonadotropic properties. (From Wikipedia)
Prostaglandins A, Synthetic definition: Analogs or derivatives of prostaglandin A that do not occur naturally in the body. They do not include the product of the chemical synthesis of hormonal PGA.
Prostaglandins E, Synthetic definition: Analogs or derivatives of prostaglandins E that do not occur naturally in the body. They do not include the product of the chemical synthesis of hormonal PGE.
Prostaglandins F, Synthetic definition: Analogs or derivatives of prostaglandins F that do not occur naturally in the body. They do not include the product of the chemical synthesis of hormonal PGF.
Prostaglandins, Synthetic definition: Compounds obtained by chemical synthesis that are analogs or derivatives of naturally occurring prostaglandins and that have similar activity.
prostaglandin analog definition: synthetic or natural chemical compounds which resemble naturally occurring prostaglandins in structure and/or function.
Resins, Synthetic definition: Polymers of high molecular weight which at some stage are capable of being molded and then harden to form useful components.
Secretin definition: A peptide hormone of about 27 amino acids from the duodenal mucosa that activates pancreatic secretion and lowers the blood sugar level. (USAN and the USP Dictionary of Drug Names, 1994, p597)
secretin definition: strongly basic polypeptide hormone secreted by the duodenal and jejunal mucosa that activates pancreatic secretion and lowers the blood sugar level; it has a lesser stimulatory effect on bile and intestinal secretion.
synthetic antigen definition: small synthetic peptides that mimic surface antigens of pathogens and are immunogenic.
Vaccines, Synthetic definition: Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified.
synthetic vaccine definition: vaccine consisting mainly of synthetic peptides, carbohydrates, or antigens.
Bone Matrix Implants, Synthetic definition: Bone matrix implants made of artificial (i.e., synthetic) materials designed to provide osteoconductive bone tissue scaffolds. These implants are typically made of ceramics (e.g., tricalcium phosphate, hydroxyapatite) and, less frequently, of bioactive glasses or biodegradable polymers. These implants are used to fill cystic defects, to repair fractures of the tibial plateau, and to extend autogenous bone grafts and in dental procedures (e.g., to treat periodontal degeneration and gingival recession). Bone matrix implants combined with osteoconductive growth factors and osteogenic cells (i.e., composite grafts) are frequently used instead of autologous grafts and allografts.
Synthesis Chemistry definition: A specialized branch of chemistry dealing with the making of compounds, generally from the building blocks to the larger or complex molecules. e.g. making protein from amino acids, or DNA from nucleotides.
Levothyroxine definition: A synthetic levoisomer of thyroxine (T4), similar to the endogenous hormone produced by the thyroid gland. Thyroxine is de-iodinated to form triiodothyronine (T3) in the peripheral tissues. T3 enters the cell and binds to nuclear thyroid hormone receptors, and the hormone-receptor complex in turn triggers gene expression and produces proteins required in the regulation of cellular respiration, thermogenesis, cellular growth and differentiation, and metabolism of proteins, carbohydrates and lipids. T4 and T3 also possess cardiac stimulatory effect.
Synthesis definition: The process of producing a chemical compound, usually by the union of simpler chemical compounds.
Sutures, Synthetic definition: Sutures made of synthetic polymer fibers. These sutures may be made of absorbable (i.e., biodegradable) or nonabsorbable (i.e., non biodegradable) materials; typically, absorbable sutures are made of polyglycolic acid and derivatives, lactic acid, or caprolactone, while nonabsorbable sutures are made of more common polymers (e.g., polypropylene, polyester, nylon). The type of natural suture used depends on the size and location of the wound, the strength and period of use required, cosmetic effect desired, and/or other clinical or physical needs. Synthetic sutures are typically available in sterile sections (e.g., 18, 30 inches/45, 76 cm long) attached to a single-use needle as an integral device; they are frequently colored for easy identification during surgery.
