The predisposition of black people to salt (NaCl)-sensitive essential hypertension may relate to racial differences in cellular Na+ metabolism. This tenet was investigated by examining the Na(+)-H+ antiport in serially passed skin fibroblasts from blacks and whites. Na(+)-dependent stimulation of the Na(+)-H+ antiport by cellular acidification resulted in a greater maximal velocity (Vmax) (mean...

We studied the blood pressure, natriuretic, kaliuretic and humoral responses of 347 normal subjects after volume expansion and volume contraction to examine possible differences among whites, blacks and subjects of different ages. According to outpatient 24-hour urine collections, blacks excreted less sodium and potassium than whites. After similar states of sodium intake were achieved among al...

Case Presentation: A 42-year-old black woman is diagnosed with idiopathic (unprovoked) lowerextremity deep vein thrombosis (DVT) after presenting with leg swelling. She is treated with anticoagulation for 6 months without major complications and with stable international normalized ratios, and her lower-extremity symptoms completely resolve. She has sickle cell trait but no other chronic condit...

Our specific aim in this study was to assess the family resemblance for lipids and lipoproteins in blacks randomly selected from the Princeton School District's Family Study cohort, and compare the family resemblance of lipids and lipoproteins between the blacks and whites from the same cohort. There were 160 white and 59 black nuclear families ascertained through randomly selected family study...

the previous paper it was reported that up to seven different aromatic polycyclic hydrocarbons, including 3,4-benzpyrene, were extracted with benzene from most carbon blacks made by the furnace process, but from no channel blacks (3). This difference cannot be explained on the basis of differences in raw materials. Soot formed in the laboratory from gas, which is similar to that used in the cha...

BACKGROUND Life expectancy is shorter and mortality from cardiovascular disease higher among blacks than among whites in the United States. We studied whether place of birth was associated with mortality from cardiovascular causes among non-Hispanic black and white residents of New York City. METHODS We linked mortality records from 1988 through 1992 with 1990 U.S. census data for New York Ci...

purpose: to evaluate the relationship between central corneal thickness (cct) and optic disc area in patients with primary open angle glaucoma (poag). methods: the study was performed on patients with poag who were being followed at johns hopkins hospital. all patients underwent thorough eye examination, optic disc imaging with the heidelberg retina tomograph ii (hrt ii), and ultrasound corneal...

We propose evaluation of a multi-component home automated telemanagement system providing integrated support to both clinicians and patients in implementing hypertension treatment guidelines. In a randomized clinical study, 550 blacks with hypertension are followed for 18 months. The major components of the intervention and control groups are identical and are based on the current standard of c...

The excess of hypertension among blacks has been recognized since early in this century and explains a substantial portion of the black health disadvantage. In a cohort study begun in the 1970s, hypertension accounted for 20% of all-cause mortality among blacks, compared to 10% among whites. National data on trends in hypertension (140/90 mm Hg or treatment) prevalence from 1960 to 1990 suggest...

Microporous carbon blacks can be characterized by the same techniques as activated carbons, using the classical DR equation and comparison plots based on non-porous materials. The CO adsorption isotherm at 273 K, combined with 2 computer modelling, also leads to an assessment of microporosity. The results agree with independent techniques such as immersion calorimetry into liquids of variable m...
