surgical streams in the flow of health care financing. the role of surgery in national expenditures: what costs are controllable?	the dollar flow in united states medical care has been analyzed in terms of a six-level model; this model and the gross 1981 flow data are set forth. of the estimated $310 billion expended in 1981, it is estimated that $85-$95 billion was the "surgical stream", i.e., that amount expended to take care of surgical patients at a variety of institutional types and including ambulatory care and surgeons' fees. some of the determinants of surgical flow are reviewed as well as controllable costs and ca ...	2010	3918514
clinical and nutritional implications of radiation enteritis.	the clinical and nutritional significance of radiation enteritis was assessed in eight patients with chronic diarrhea which followed curative doses of radiotherapy for pelvic malignancies. steatorrhea, found in seven malnourished patients, was ascribed to ileal disease or previous surgery, or to bacterial contamination of the small intestine. lactose intolerance, assessed by breath hydrogen excretion after oral lactose and by jejunal lactase levels, was found in six patients. in a subgroup of fi ...	2014	3917601

mechanism of sbcb-suppression of the recbc-deficiency in postreplication repair in uv-irradiated escherichia coli k-12.	the mechanism by which an sbcb mutation suppresses the deficiency in postreplication repair shown by recb recc mutants of escherichia coli was studied. the presence of an sbcb mutation in uvra recb recc cells increased their resistance to uv radiation. this enhanced resistance was not due to a suppression of the minor deficiency in the repair of dna daughter-strand gaps or to an inhibition of the production of dna double-strand breaks in uv-irradiated uvra recb recc cells; rather, the presence o ...	1985	3911022
