Interference of activated factor VII in apoptosis of erytholeukemic K562 cells.

Coagulation factor VIIa (FVIIa) is a key protease initiating the coagulation cascade in the presence of its receptor, tissue factor (TF). FVIIa elicits several cellular responses, probably involving other receptors(s) than TF. This study investigates the implication of recombinant FVIIa on the apoptosis of K562 erythroleukemia cells.

The face of AIDS: Effects of physical attractiveness and target gender on inferred mode of HIV infection.

We examined the effects of physical attractiveness on the assumed mode of HIV acquisition. 176 students read a description of an HIV-positive target whose photograph was placed above the description. A 2 (target gender) by 2 (attractive or unattractive target) factorial design was used.

Albuminuria in type 2 (non-insulin-dependent) diabetes mellitus and impaired glucose tolerance in Pima Indians.

The prevalence of abnormal urinary albumin excretion, defined by a urine albumin to creatinine ratio greater than or equal to 30 mg/g (approximately equivalent to an albumin excretion rate of greater than or equal to 30 mg/24 h), was determined in 2728 Pima Indians aged greater than or equal to 15 years from the Gila River Indian Community in Arizona, a population with a high prevalence of Type 2 (non-insulin-dependent) diabetes mellitus. Excessive albumin excretion was present in 8% of subjects with normal glucose tolerance, 15% of those with impaired glucose tolerance, and 47% of subjects with diabetes. The intermediate prevalence of abnormal albuminuria in those with impaired glucose tolerance suggests that hyperglycaemia even at levels below those diagnostic of diabetes is associated with renal abnormalities in some subjects and that these abnormalities may precede the onset of diabetes.

Incidence of proteinuria in type 2 diabetes mellitus in the Pima Indians.

Little is known of the natural history of nephropathy in type 2 (non-insulin-dependent) diabetes, yet type 2 diabetes is a major cause of end-stage renal disease in the United States. The incidence rate of heavy proteinuria was determined in Pima Indians participating in a longitudinal population study of diabetes and its complications. Heavy proteinuria was defined by a urine protein (g/liter) to urine creatinine (g/liter) ratio greater than or equal to 1.

Incidence of end-stage renal disease in type 2 (non-insulin-dependent) diabetes mellitus in Pima Indians.

The incidence of end-stage renal disease was determined in the Pima Indians of the Gila River Indian Community in Arizona, a population with a high prevalence of Type 2 (non-insulin-dependent) diabetes mellitus. Between 1975 and 1986, from a study population of 5059 subjects, end-stage renal disease occurred in 80 persons, 76 (95%) of whom had Type 2 diabetes. A review of the cases with end-stage renal disease indicated that among the diabetic subjects only two cases could be attributed to nondiabetic renal disease; all other cases were attributable to diabetic nephropathy.
