Example Input: Abstract: In chronically catheterized rats hepatic glycogen was increased by fructose (approximately 10 g/kg) gavage (FF rats) or lowered by overnight food restriction (FR rats). [3-3H]- and [U-14C]glucose were infused before, during, and after treadmill running. During exercise the increase in glucose production (Ra) was always directly related to work intensity and faster than the increase in glucose disappearance, resulting in increased plasma glucose levels. At identical work-loads the increase in Ra and plasma glucose as well as liver glycogen breakdown were higher in FF and control (C) rats than in FR rats. Breakdown of muscle glycogen was less in FF than in C rats. Incorporation of [14C]glucose in glycogen at rest and mobilization of label during exercise partly explained that 14C estimates of carbohydrate metabolism disagreed with chemical measurements. In some muscles glycogen depletion was not accompanied by loss of 14C and 3H, indicating futile cycling of glucose. In FR rats a postexercise increase in liver glycogen was seen with 14C/3H similar to that of plasma glucose, indicating direct synthesis from glucose. In conclusion, in exercising rats the increase in glucose production is subjected to feedforward regulation and depends on the liver glycogen concentration. Endogenous glucose may be incorporated in glycogen in working muscle and may be used directly for liver glycogen synthesis rather than after conversion to trioses. Fructose ingestion may diminish muscular glycogen breakdown. The [14C]glucose infusion technique for determination of muscular glycogenolysis is of doubtful value in rats.

Example Input: Abstract: Coronary angioplasty was performed in 53 patients in whom unstable angina had reoccurred after 48 hr and within 30 days after sustained myocardial infarction. Single-vessel disease was present in 64% of the patients and multivessel disease in 36%. The preceding myocardial infarction had been small to moderate in size in the majority of the patients. The left ventricular ejection fraction was more than 50% in 80% of the patients. Forty-five patients were refractory to pharmacologic treatment; eight were initially stabilized but once again became symptomatic with light exertion. Angioplasty was performed in 35 patients 2 to 14 days and in 18 patients 15 to 30 days after infarction (average 12 +/- 7 days after infarction). The initial success rate was 89% (47/53). The success rate of the patients treated at 2 to 14 days was lower (29/35, 83%) than that of patients treated at 14 to 30 days (18/18, 100%) but did not reach statistical significance (p less than .06). There were no deaths related to the procedure. In four of the six failures, emergency bypass surgery was performed and two patients sustained a myocardial infarction. Furthermore, a myocardial infarction complicated the angioplasty procedure in two other patients; thus the overall procedure-related myocardial infarction rate was 8% (4/53). At 6 months follow-up 26% (14/53) of all the patients who underwent angioplasty had recurrence of angina, which was successfully treated with repeat angioplasty, bypass surgery, or medical therapy. There were no late deaths. Late myocardial infarction occurred in two patients. Thus the total myocardial infarction rate after angioplasty at 6 months was 11% (6/53 patients).(ABSTRACT TRUNCATED AT 250 WORDS)

Example Input: Abstract: Using a series of graded destabilizing forces, we have developed a simple quantitative test of the postural response: the Postural Stress Test (PST). Suitable for widespread testing of elderly subjects, the test evaluates the subject's ability to avoid a fall as well as the appropriateness of the response. We have determined that by comparison with young subjects, the elderly controls have compromised although functionally effective balance. On the other hand, the balance response was severely compromised in half of the individuals with a history of falls. Experience with the Postural Stress Test suggests it will predict those elderly individuals with a tendency to fall as well as provide a simple mechanism for studying the balance response in the elderly.
