| slow scan | <microscopy> A system of video scanning in which the time used to read each line has been increased in comparison to standard video. The bandwidth needed to faithfully transmit or record the signal is reduced in inverse ratio to the scanning time. Slow scan allows the video signal to be transmitted over a telephone line, or line scans to be registered on a chart recorder. (19 Jan 1998) |

| slow virus | 1. <virology> Specifically one of the Lentivirinae 2. Any virus causing a disease that has a very slow onset. Diseases such as sub acute spongiform encephalopathy, Aleutian disease of mink, scrapie, kuru and Creutzfeldt Jacob disease may be caused by slow viruses. See: prion. (18 Nov 1997) |
| slow virus disease | A disease that follows a slow, progressive course spanning months to years, frequently involving the central nervous system, and ultimately leading to death, such as visna and maedi of sheep, caused by viruses of the subfamily Lentivirinae (family Retroviridae), and subacute sclerosing panencephalitis, seemingly caused by the measles virus; spongiform encephalopathies including kuru of man, scrapie of sheep, and transmissible encephalopathy of mink may also be classified under slow virus disease but their respective aetiologic agents have not been adequately characterised. (05 Mar 2000) |
| slow virus diseases | Diseases of viral origin, characterised by incubation periods of months to years, insidious onset of clinical manifestations, and protracted clinical course. Though the disease process is protracted, viral multiplication may not be unusually slow. Conventional viruses produce slow virus diseases such as subacute sclerosing panencephalitis, progressive multifocal leukoencephalopathy (leukoencephalopathy, progressive multifocal), and aids. Diseases produced by unconventional agents were originally considered part of this group. They are now called prion diseases. (12 Dec 1998) |
| nasal feeding | The giving of nourishment through a flexible tube passed through the nasal passages into the stomach. (05 Mar 2000) |
| feeding | Giving food or nourishment. (05 Mar 2000) |
| feeding and eating disorders of childhood | Mental disorders related to feeding and eating that are usually diagnosed in infancy or early childhood. (12 Dec 1998) |
| feeding behaviour | Behavioural responses or sequences associated with eating including modes of feeding, rhythmic patterns of eating, and time intervals. (12 Dec 1998) |
| feeding, breast | The ability of the breast to produce milk diminishes soon after childbirth without the stimulation of breastfeeding. Immunity factors in breast milk can help the baby to fight off infections. Breast milk contains vitamins, minerals, and enzymes which aid the baby's digestion. Breast and formula feeding can be used together. (12 Dec 1998) |
| feeding centre | A region of the lateral zone of the hypothalamus, electrical stimulation of which in the rat elicits uninterrupted eating; destruction of the region causes long-lasting anorexia. (05 Mar 2000) |
| feeding methods | Methods of giving food to humans or animals. (12 Dec 1998) |
| feeding tube | A flexible tube passed through the oral pharynx and into the oesophagus and stomach, through which liquid food is fed. (05 Mar 2000) |
| fictitious feeding | A procedure used in the study of the psychic phase of gastric secretion: in experiments on dogs, the food, after being eaten, does not enter the stomach but issues from an oesophageal fistula made in the neck; the chewing and swallowing of food causes an abundant secretion of gastric juice. Synonym: fictitious feeding. (05 Mar 2000) |
| forced feeding | Giving liquid food through a nasal tube passed into the stomach, forcing a person to eat more food than desired. Synonym: forced alimentation. (05 Mar 2000) |
| formula feeding | The ability of the breast to produce milk diminishes soon after childbirth without the stimulation of breastfeeding. Immunity factors in breast milk can help the baby to fight off infections. Breast milk contains vitamins, minerals, and enzymes which aid the baby's digestion. Breast and formula feeding can be used together. (12 Dec 1998) |
