Cardiorespiratory responses to progressive exercise were examined in 38 children who had undergone heart (n = 16), heart-lung (n = 13), or double-lung (n = 9) transplantation, and in 41 healthy controls. The four groups were similar in age, but the control subjects and heart transplant recipients were significantly larger than the heart-lung and lung recipients as assessed by body mass index (B...

Antitumor Activity, Phosphorus Compounds A series of pentavalent phosphorus compounds containing the nitroxyl and/or aziridinyl moieties was evaluated for antitumor activity against P 388 and L 1210 lymphocytic leukemias, and compared to the clinical agent thio-TEPA (1). The compounds with the structures 5-13 were found to be active, with a T/C value greater than 125. The percent ILS was also d...

BACKGROUND In critically ill patients who are receiving mechanical ventilation, the factors associated with physicians' decisions to withdraw ventilation in anticipation of death are unclear. The objective of this study was to examine the clinical determinants that were associated with the withdrawal of mechanical ventilation. METHODS We studied adults who were receiving mechanical ventilatio...

Three filters in series were employed to separate into groups, according to size, the nuclear debris suspended in air at ground level. The concentrations of airborne Ce(144)-Pr(144), Sb(125), Cs(137), Zr(95)-Nb(95), Mn(54), and Ru(106)-Rh(106) in each size group were determined by gamma spectral analysis. Particles having diameters of less than 1.75 microns contained a minimum of 88 percent of ...

PURPOSE Gastroenterologists have been seeking reliable noninvasive indices of inflammatory and malignant bowel disease. This prospective study was to assess the value of fecal calprotectin in predicting abnormal histologic findings in patients undergoing colonoscopy. METHODS Stool specimens supplied before colonoscopy by 72 consecutive patients were measured for calprotectin levels, and the f...
