Pulmonary vascular resistance and the risk of heart transplantation.

Elevated pulmonary vascular resistance was an incremental risk factor for premature death after heart transplantation (p = 0.0002). Its effect was continuously variable and not dichotomous (yes or no).

Morphometric evidence for non-pressure-related arterial wall thickening in hypertension.

To investigate the relation of pressure and vascular wall thickening in hypertension, we coarcted the abdominal aorta upstream to the renal arteries in 14 rats. Sham-coarcted (n = 16) and two-kidney, one-clip (Goldblatt) hypertensive rats (n = 13) served as controls. Tail, femoral, and carotid arterial pressures rose (p less than 0.

Topography of human intelligence across race: factorial comparison of black-white WAIS-R profiles for criminal offenders.

Comparison of intellectual functioning across racial groups is an important scientific issue with broad interdisciplinary implications. A large random sample (N = 275) of Black and White incarcerated individuals were studied to evaluate the topography of intelligence across race. Principal factor analyses yielded the general intelligence-g factor along with specific Verbal Comprehension and Perceptual Organization dimensions.
