Input: Consider Input: Abstract: This paper reports the Authors' 8 year experience in the clinical use of charcoal hemoperfusion as a means to reduce the weekly time of treatment in chronic uremic patients. Two different programmes were applied. Programme A (34 patients) which involved substituting the 3 procedures per week of standard dialysis (4 hours duration each) by 2 procedures of combined hemodialysis and hemoperfusion, again of 4 hours duration each. Programme B (18 patients) which involved substituting the 3 procedures per week of 4 hours duration by 3 procedures of 3 hours each, 2 of combined hemodialysis and hemoperfusion, 1 of conventional dialysis. The net weekly reduction was 33% for Programme A and 25% for Programme B. The efficacy of the two Programmes was evaluated by clinical, hematochemical, nutritional and instrumental parameters.

Output: Hemoperfusion in reduced-time programmes for chronic uremia. Long-term results.

Input: Consider Input: Abstract: A method is described for obtaining nondistorted, reproducible phosphoglucomutase-1 subtyping patterns from semen stains and bloodstains. Isoelectric focusing of phosphoglucomutase-1 was accomplished in 80 min in a 0.2-mm-thick polyacrylamide gel with an interelectrode wick distance of 8.0 cm. The gel contained 1.2% (w/v) N-(2-hydroxyethyl) piperazine-N-3-propanesulfonic acid (EPPS) and pH 5 to 7 ampholytes (4% w/v). When maintained at room temperature, laboratory-prepared bloodstains and semen stains could be typed for phosphoglucomutase-1 up to four months and three weeks, respectively. An evaluation of phosphoglucomutase-1 typing by isoelectric focusing and the Group I system was performed on casework samples submitted to the FBI Laboratory. In addition to the increased discriminating probability of phosphoglucomutase-1 when subtyped, isoelectric focusing yielded an increase in positive calls on questioned bloodstains (65.6 versus 36.2%) and dried seminal stains (16.4 versus 13.1%) compared with the Group I system.

Output: Subtyping phosphoglucomutase-1 in semen stains and bloodstains: a report on the method.

Input: Consider Input: Abstract: Seventy-six white and black low-income families were interviewed weekly during 1 month to determine how much they spent on food using Food Stamps, WIC coupons, and cash and how much additional food they obtained from different food and meals programs. After families had received their public assistance and Food Stamp allotments for the month, a 24-hour recall was obtained each week from each family member so that food intake could be monitored from the recalls as food-buying resources were depleted. Although families bought most of their food the first 2 weeks, they maintained a relatively constant food intake through the last week of the month. However, when nutrient intakes were compared with Recommended Dietary Allowances, the diets were found to be well supplied in protein, ascorbic acid, thiamin, niacin, riboflavin, vitamin B-12, vitamin A, and phosphorus, and inadequately supplied in vitamin B-6, vitamin D, vitamin E, iron, calcium, magnesium, zinc, and pantothenic acid. Since that finding was true not just at the end of the month but from the beginning, it indicated that the nutrition problems of low-income families are not intermittent, but continuous.
Output: Food procurement and the nutritional adequacy of diets in low-income families.
