| 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.

|---|---|
| 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) |
| drift cyclotron loss cone instabilities | (DCLC) This is an electrostatic microinstability (frequencies at harmonics of the ion cyclotron frequency) which is of major concern in small mirror devices. Mode is driven by radial gradients in the electron density, and causes loss of ions due to non-conservation of magnetic moment (see adiabatic invariant) as they interact with the mode, and are dispersed in velocity space into the loss cone. Stabilisation is accomplished by increasing the plasma size and by partially filling the loss cone with a continuous extermal warm plasma stream. (09 Oct 1997) |
| icecream cone | <radiology> Ball of icecream head of malleus, cone body of incus (12 Dec 1998) |
| implantation cone | <cell biology> Tapering region between a neuron's cell body and its axon. This region is responsible for summating the graded inputs from the dendrites and producing action potentials if the threshold is exceeded. (12 Mar 1998) |
| inverted cone bur | A rotary cutting instrument in the shape of a truncated cone with the smaller end attached to the shaft; generally used for entering carious pits or creating undercuts in cavity preparations. (05 Mar 2000) |
| ocular cone | The cone of light in the interior of the eyeball with the base formed by the rays entering through the pupil and the apex focused on the retina. (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) |
| theca interna cone | The conical thickening of thecal cells of an ovarian follicle with its apex pointed toward the surface. (05 Mar 2000) |
| elastic cone | Thicker lower portion of the elastic membrane of the larynx, extending between the cricoid cartilage and the vocal ligaments, the latter actually being a thickening of the free, superior margin of the conus elasticus. Synonym: cricovocal membrane, elastic cone. Synonym: cricothyroid ligament. (05 Mar 2000) |
| twin cone | Two retinal cone's fused together. (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) |
