| ATF | activating transcription factor; anterior talofibular [ligament]; ascites tumor fluid |
|---|---|
| ENA | epithelial neutrophil-activating [protein]; extractable nuclear antigen |
| ERTAS | extended reticulo-thalamic activating system |
| FAF | fatty acid free; fibroblast-activating factor |
| FLAP | 5-lipoxygenase activating protein |
| leader peptide | <molecular biology> In the regulation of gene expression for enzymes concerned with amino acid synthesis in prokaryotes, the leader sequence codes for the leader peptide that contains several residues of the amino acid being regulated. Transcription is closely linked to translation and if translation is retarded by limited supply of amino acyl tRNA for the specific amino acid, the mode of transcription of the leader sequence permits full transcription of the operon genes, otherwise complete transcription of the leader sequence prematurely terminates transcription of the operon.

| lysergyl peptide synthetase | <enzyme> Multifunctional enzyme which forms non-cyclol d-lysergyl peptide lactams; consists of two polypeptide chains - lps 1 binds the 3 amino acids (ala, phe and pro) of the peptide nucleus and lps 2 binds d-lysergic acid Registry number: EC 6.3.2.- Synonym: d-lysergylpeptide synthetase (26 Jun 1999) |
| adenoid tissue | A structure found within the lymphatic system that consists of lymphocytes within a network of fibres. (09 Oct 1997) |
| adipose tissue | <anatomy> Connective tissue that has been specialised to store fat. See: adipocyte. (25 Jun 1999) |
| aerenchymous tissue | A type of plant tissue in which cells are unusually large, resulting in large air spaces in the plant organ, such tissues are often referred to as spongy and usually provide increased buoyancy. (09 Oct 1997) |
| areolar tissue | Loose, irregularly arranged connective tissue that consists of collagenous and elastic fibres, a protein polysaccharide ground substance, and connective tissue cells (fibroblasts, macrophages, mast cells, and sometimes fat cells, plasma cells, leukocytes, and pigment cells). (05 Mar 2000) |
| bone tissue | A connective tissue, the matrix of which consists of collagen fibres and ground substance and in which are deposited calcium salts (phosphate, carbonate, and some fluoride) in the form of an apatite. Synonym: bone tissue. (05 Mar 2000) |
| border tissue movements | The action of the muscles and other tissues adjacent to the borders of a denture. (05 Mar 2000) |
| brain tissue transplantation | Transference of brain tissue, either from a foetus or from a born individual, between individuals of the same species or between individuals of different species. (12 Dec 1998) |
| brown adipose tissue | A thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including man. It is prominent in the newborn of all species in which it occurs and remains a distinct and conspicuous tissue in the adults of certain species, especially those that hibernate. It is also called brown adipose tissue. (12 Dec 1998) |
| cancellous tissue | Latticelike or spongy osseous tissue. (05 Mar 2000) |
| cardiac muscle tissue | See: cardiac muscle. (05 Mar 2000) |
| Gamgee tissue | A thick layer of absorbent cotton between two layers of absorbent gauze, used in surgical dressings. (05 Mar 2000) |
| gelatinous tissue | A type of connective tissue little differentiated beyond the mesenchymal stage; its ground substance of glycoproteins is abundant and contains fine collagenous fibres and fibroblasts; in its most characteristic form, it appears in the umbilical cord as Wharton's jelly. Synonym: gelatinous tissue. (05 Mar 2000) |
| Verhoeff's elastic tissue stain | <technique> A stain for tissue sections in which a mixture of haematoxylin, ferric chloride, and Lugol's iodine solution is used; tissue may be counterstained, if desired, with eosin or van Gieson's stain; elastic fibres and nuclei appear blue-black to black while collagen and other components are shades of pink to red.
