| nuclear chain fibre | The shortest and most numerous type of intrafusal muscle fibre's in a neuromuscular spindle, containing a single row of centrally positioned nuclei. (05 Mar 2000) |
|---|---|
| diabetes and fibre | Soluble fibres (oat bran, apples, citrus, pears, peas/beans, psyllium, etc.) slow down the digestion of carbohydrates (sugars), which results in better glucose metabolism. Some patients with the adult-onset diabetes may actually be successfully treated with a high-fibre diet alone, and those on insulin, can often reduce their insulin requirements by adhering to a high-fibre diet. (12 Dec 1998) |
| dietary fibre | <nutrition> The remnants of plant cell walls that are resistant to digestion by the alimentary enzymes of man. It comprises various polysaccharides and lignins. (12 Dec 1998) |
| diverticulosis/diverticulitis and fibre | High fibre diets help delay the progression of diverticulosis and, at least, reduce the bouts of diverticulitis. (12 Dec 1998) |
| outer cone fibre | Located between the inner segment and the cell body. (05 Mar 2000) |
| T fibre | A fibre that branches at right angles to the right and left; term used to describe the branching patterns of granular cell axons in the molecular layer of the cerebellum. (05 Mar 2000) |
| Kuhne's fibre | Artificial muscle fibre made by filling the intestine of an insect with a growth of myxomycetes; used to demonstrate the contractility of protoplasm. (05 Mar 2000) |
| fibre | A substance found in foods that come from plants (fruits and vegetables) and typically cannot be digested. Also called bulk or roughage. Fibre helps in the digestive process and is thought to lower cholesterol and help control blood glucose. The two types of fibre in food are soluble and insoluble. Soluble fibre, found in beans, fruits, and oat products, dissolves in water and is thought to help lower blood fats and blood glucose. Insoluble fibre, found in whole-grain products and vegetables, passes directly through the digestive system, helping to rid the body of waste products and possibly prevent diseases such as colon cancer. High fibre diets help delay the progression of diverticulosis and, at least, reduce the bouts of diverticulitis. In many cases, it helps reduce the symptoms of the Irritable Bowel Syndrome (IBS) (also called spastic colitis, mucus colitis, and nervous colon syndrome.) It is generally accepted that a diet high in fibre is protective, or at least reduces the incidence, of colon polyps and colon cancer. Soluble fibre substances are effective in helping reduce the blood cholesterol. This is especially true with oat bran, fruits, psyllium and legumes. High soluble-fibre diets may lower cholesterol and low-density lipoproteins ( the 'bad' lipoproteins ) by 8% to 15%. Insoluble fibre retains water in the colon, resulting in a softer and larger stool. It is used effectively in treating constipation resulting from poor dietary habits. Bran is particularly rich in insoluble fibre. Soluble fibres (oat bran, apples, citrus, pears, peas/beans, psyllium, etc.) slow down the digestion of carbohydrates (sugars), which results in better glucose metabolism. Some patients with the adult-onset diabetes may actually be successfully treated with a high-fibre diet alone, and those on insulin, can often reduce their insulin requirements by adhering to a high-fibre diet.

| fibre cell | <plant biology> Greatly elongated type of plant cell with very thick lignified wall. Usually dead at maturity, this cell type is specialised for the provision of mechanical strength. Fibre cells and sclereids together make up the tissue known as sclerenchyma. (18 Nov 1997) |
| leukodystrophy with diffuse Rosenthal fibre formation | A metabolic disorder whose onset can be in infancy, adolescence, or adulthood; characterised pathologically by widespread cerebral demyelination with astrocyte and primitive oligodendroglial cell proliferation; refractile Rosenthal fibres result from the degeneration of these proliferating cells; aetiology unknown, but possibly due to a metabolic defect of astrocytes; sex-linked recessive disorder.

| anterior white commissure | A narrow band of white substance bordering on the anterior median fissure of the spinal cord in front of the anterior gray commissure, and consisting of nerve fibres crossing over from one half of the spinal cord to the other. Synonym: commissura alba, anterior white commissure, commissura ventralis alba, ventral white column. (05 Mar 2000) |
| blue white colour selection | <molecular biology, procedure> Method for identifying bacterial clones containing plasmids with inserts. Many modern vectors have their polycloning site within a part of the LacZ gene encoding _ galactosidase, which provides _ complementation in an appropriate mutant E. Coli strain. This means that a re ligated (empty) vector will produce blue colonies when grown on plates containing IPTG and X gal, but colonies with a substantial insert in their plasmid's polycloning site are unable to produce functional _ galactosidase and so produce white colonies. (16 Dec 1997) |
| Bouffardi's white mycetoma | <dermatology> A form of mycetoma common in India and found occasionally in Somalia, caused by the organism Streptomyces somaliensis; in this variety, the muscles, tendons, and bones of the foot are destroyed by the disease process; numerous draining sinuses discharge yellowish grains, clustered like fish roe. (05 Mar 2000) |
| Brumpt's white mycetoma | Mycetoma caused by Pseudallescheria boydii, occurring in temperate and subtropical areas in India; small, white to yellow, hard to soft granules are discharged through the draining sinuses. (05 Mar 2000) |
| ventral white column | A narrow band of white substance bordering on the anterior median fissure of the spinal cord in front of the anterior gray commissure, and consisting of nerve fibres crossing over from one half of the spinal cord to the other. Synonym: commissura alba, anterior white commissure, commissura ventralis alba, ventral white column. (05 Mar 2000) |
