| organic level | The amount of organic matter prescribed to be left after logging. (05 Dec 1998) |
|---|---|
| trophic level | <biology> Stage in a food chain or web leading from primary producers (lowest trophic level) through herbivores to primary and secondary carnivores (consumers- highest level). (09 Oct 1997) |
| lactate level | A test that measures the amount of lactic acid in the blood. Lactic acid is an intermediate product of carbohydrate metabolism and is derived mainly from muscle cells and red blood cells. Exercise will normally raise lactic acid levels. Conditions of oxygen deprivation (for example shock, heart failure, lung disease) will trigger anaerobic metabolism within muscle tissue resulting in lactic acid build up in the tissues. Normal lactic acid levels are 4.5 to 19.8 mg/dl. (27 Sep 1997) |
| lactic acid level | <investigation> A test that measures the amount of lactic acid in the blood. (25 Jun 1999) |
| free calcium level | <biochemistry> The ionised calcium represents the calcium (Ca++) that is the metabolically active calcium. Normal values for ionised calcium in the bloodstream should be 4.4 to 5.3 mg/dl for adults and 4.4 to 6.0 mg/dl for children. Elevations may be seen in hyperparathyroidism, metastatic bone tumour, milk-alkali syndrome, multiple myeloma, Paget's disease, sarcoidosis, PTH-secreting tumours (paraneoplastic syndrome) and vitamin D intoxication. Lower than normal values may be seen in hypoparathyroidism, malabsorption, osteomalacia, pancreatitis, renal failure, rickets and vitamin D deficiency. (27 Sep 1997) |
| level of aspiration | <psychology> The degree or quality of performance (exhibited in a testing situation) which an individual desires to attain or feels he can achieve. (05 Mar 2000) |
| adrenocortical hormones | Hormone's secreted by the human adrenal cortex; e.g., cortisol, aldosterone, corticosterone. (05 Mar 2000) |
| adrenomedullary hormones | Hormones produced by the adrenal medulla, particularly the catecholamines epinephrine and norepinephrine. (05 Mar 2000) |
| pancreatic hormones | Peptide hormones secreted into the blood by cells in the islets of langerhans of the pancreas. The alpha cells secrete glucagon; the beta cells secrete insulin; the delta cells secrete somatostatin; and the pp cells secrete pancreatic polypeptide. (12 Dec 1998) |
| gastrointestinal hormones | Hormones that originate in and regulate motor and secretory activity of the digestive organs. (12 Dec 1998) |
| parathyroid hormones | Polypeptide hormones (84 amino acid residues) secreted by the parathyroid glands, which promote release of calcium from bone to extracellular fluid by activating osteoblasts and inhibiting osteoclasts, indirectly promote increased intestinal absorption of calcium, and promote renal tubular reabsorption of calcium and increased renal excretion of phosphates. It is a major regulator of bone metabolism. Secretion of parathyroid hormone increases when the level of calcium in the extracellular fluid is low. Its action is opposed by calcitonin. (12 Dec 1998) |
| vertebrate hormones | Hormones synthesised in vertebrates. (05 Mar 2000) |
| glycoprotein hormones, alpha subunit | A non-covalently bound subunit of the glycoprotein hormones tsh, fsh, lh, and hcg which originates in the anterior pituitary gland and placenta. This subunit is virtually identical in structure and indistinguishable by radioimmunoassay in all of the above glycoproteins. It is present in both men and women, but is elevated in postmenopausal women and in patients with hypothyroidism, uraemia and malignant tumours. The alpha subunit may be involved directly in recognition of certain receptors. (12 Dec 1998) |
| gonadal hormones | Hormones having oestrogenic (female sex hormones) or androgenic (male sex hormones) activity. (12 Dec 1998) |
| pituitary hormone release inhibiting hormones | Polypeptide hormones produced in the hypothalamus which inhibit the release of pituitary hormones. (12 Dec 1998) |
