Lipoprotein profile changes during intense training of Israeli military recruits.

The effect of prolonged strenuous military training on serum lipoproteins was studied in 73 new recruits. Dietary intake, body weight, and average energy expenditure were recorded, and blood samples collected at three time periods before training began (time 0), and after 6 and 12 wk of intense physical activity (times I and II, respectively). There was a significant increase in high density lipoprotein (HDL) cholesterol and a decrease in low density lipoprotein (LDL) cholesterol accompanying an increase of duration and intensity of exercise.

Drug Research: an institutional methodology.

The author raises the question of whether or not valid qualitative data on various aspects of drug use can be collected from recovering addicts in institutional settings. To address this issue the author explores the advantages of interviewing institutionalized, recovering addicts, and evaluates the following field practices: 1) using active street addicts as informants, 2) recruiting recovering addicts as "tour guides" (i.e.

Drug user settings: a crack house typology.

Both lay persons and members of the scientific community have come to view the inner-city crack house as a facility where drug dealers and crack addicts sell, buy, and use crack cocaine. It is suggested in this article that the term "crack house" be unbundled into four more meaningful terms based on the physical conditions of the house, its functionality, and the social relationships that it supports. Two typologies are proposed.

Lipids and lipoproteins among Ethiopian immigrants: comparison of operations Solomon and Moses.

Lipid and lipoprotein levels and body mass index were compared between two immigrations of Ethiopian Jews to Israel. Those who came in Operation Moses in 1984-85 were survivors of a long trek across hundreds of kilometers and severe food deprivation. Those who immigrated in Operation Solomon in 1991 were bussed from their villages to Addis Ababa where public health care and food were provided and a few months later they were airlifted to Israel.

The development of the chymotryptic activity during postnatal life using the bentiromide test.

The chymotryptic activity was assessed in 40 newborns and infants age 3-180 days using the NBT-PABA test. Nine newborns were studied serially at different age periods. A group of 18 cystic fibrosis patients and a group of 17 healthy children served as pancreatic insufficient and pancreatic sufficient controls, respectively.
