Renin, the renal pressor substance, was discovered and described by Tigerstedt and Bergman in classic experiments published in 1898. It was not, however, until 1934 that Goldblatt identified the relevance of renin by showing that renal secretion of renin caused sustained renovascular hypertension in dogs. Others subsequently demonstrated that renin itself is not the pressor element, but rather ...

To improve the understanding on CNT growth modes, the various processes, including thermal CVD, MP-CVD and ECR-CVD, have been used to deposit CNTs on nanoporous SBA-15 and Si wafer substrates with C(2)H(2) and H(2) as reaction gases. The experiments to vary process parameter of DeltaT, defined as the vector quantities of temperature at catalyst top minus it at catalyst bottom, were carried out ...

BACKGROUND Results from observational and genetic epidemiological studies suggest that lower serum homocysteine levels are associated with lower incidence of cardiovascular disease (CVD). Numerous randomized controlled trials have investigated the efficacy of lowering homocysteine with folic acid supplementation for CVD risk, but conflicting results have been reported. METHODS AND RESULTS Thr...

Title: CIRCULATING BIOMARKERS OF NITROOXIDATIVE STRESS IN YOUNG AND OLDER ACTIVE AND INACTIVE MEN Lori Beth Bjork, M.A., 2010 Directed By: Professor James M. Hagberg, PhD Department of Kinesiology Oxidative stress markers may be novel factors contributing to cardiovascular (CVD) risk. The purpose of this study was to examine the effects of long-term exercise, age, and their interaction on the p...

1. Introduction The surface trap of AlGaN/GaN high electron mobility transistors (HEMTs) can cause current collapse phenomenon which is the most serious limiting factor of the device's output power at high frequency operation. The surface passivation is a key step to reduce surface state effects and the quality of surface passivation film is very important [1]. Silicon nitride (SiNX) is widely ...

BACKGROUND This is an observational study undertaken in aim to evaluate the association between metabolic syndrome (MS) and high homocysteinemia (HHcy) in relation with cardiovascular disease (CVD). METHODS The study involved 126 subjects with angiographically documented CVD and 65 healthy subjects. MS has been diagnosed according to the ATP III criteria and plasma homocysteine concentration ...

CONTEXT Elevated levels of retinol binding protein-4 (RBP4) are positively correlated with insulin resistance, obesity, diabetes mellitus, and cardiovascular disease (CVD). Subclinical hypothyroidism (SCH) has also been associated with CVD; however, the factors linking SCH to CVD are not clear. OBJECTIVE The objective of the study was to evaluate risk factors for CVD in elderly patients group...

BACKGROUND Increased plasma activity of gamma-glutamyltransferase (GGT) is associated with cardiovascular diseases (CVD) and mortality in the general population. We investigated the association between GGT, CVD and mortality in individuals with diabetes mellitus. METHODS Data used were from 1280 participants, aged 35-70 years, with a confirmed diagnosis of diabetes mellitus in the European Pr...

Nanocrystalline diamond films have attracted considerable attention because they have a low coefficient of friction and a low electron emission threshold voltage. In this paper, the author reviews the plasma-enhanced chemical vapor deposition (PE-CVD) of nanocrystalline diamond and mainly focuses on the growth of nanocrystalline diamond by low-pressure PE-CVD. Nanocrystalline diamond particles ...
