Data defining the isolated effect of insulin on whole body protein and glucose metabolism in cancer patients are limited. Ten normal volun teers (controls), age 55 ±3 years (mean ±SEM); 8 cancer patients, age 61 ±3years, weight loss 2 ±1% (CANWL); and 8 cancer patients, age 55 ±2 years, weight loss 18 ±2% (CAWL), were studied in the postabsorptive state. Whole body leucine kinetics were d...

Page 3. It is not entirely clear what causal model the authors have in mind, and specifically whether they consider smoking and air pollution as mediators or confounders of the association between SES and respiratory health. In paragraph two, page 1, they imply mediation (â##â#¦strongly influenced by SES..â##) but in paragraph three, confounding is implied (â##....competing factorsâ#¦â##). This...

Aniline and o-, m-, and /Moluidine, which are representative of aro matic amines in cigarette smoke, were identified and quantified in human urine. Smokers excreted 3.1 ±2.6 «¿g/24 h of aniline and 6.3 ±3.7 ¿ig/ 24 h of o-toluidine (n = 16). Nonsmokers excreted 2.8 ±2.5 Mg/24 h of aniline and 4.1 ±3.2 un; 24 h of o-toluidine (n = 12). Metaand /»toluidine were detected in the urine of 2 ...
