AIMS To examine biomarkers of oxidative stress (oxs), and endothelin (ET)-1, in hypertensive patients with atherosclerotic renal artery stenosis (ARAS) and to evaluate the effect of percutaneous transluminal renal angioplasty (PTRA). METHODS Baseline measurements were made immediately before renal angiography in patients with suspected ARAS (significant ARAS, n = 83, and non-RAS, n = 59) and ...

BACKGROUND/AIMS The contribution of emergent cardiovascular risk factors to atherosclerotic renal artery stenosis (ARAS) is debated. We investigated the relationship of lipoprotein(a) and prothrombotic factors with ARAS in hypertension. METHODS In 50 hypertensive patients with angiographic evidence of ARAS and 58 hypertensive patients who had comparable cardiovascular risk factor burden but n...

On 26 May 2003, intense rainfall from a series of thunderstorms in eastern North Carolina caused flooding that eventually destroyed the concrete dam in Hope Mills, draining Hope Mills Lake, and revealing a formerly submerged and buried structure that was identified as a timber crib dam. Inspection revealed these logs to be old-growth longleaf pines, which are now rare on the coastal plain lands...

During 1997-2007 we studied distribution and dynamics of main radionuclides and their biological significance in lake ecosystems within the 10-km inner exclusion zone around the destroyed unit of the Chernobyl nuclear power plant. The main objects of our studies were bottom sediments, water, seston, and different species of hydrobionts from Azbuchin Lake, Dalekoye-1 Lake and Glubokoye Lake. Sel...

Ethiopia began constructing the Grand Ethiopian Renaissance Dam (GERD) in 2011 on Blue Nile near borders of Sudan for electricity production. The dam was constructed as a roller-compacted concrete (RCC) gravity-type dam, comprising two power stations, three spillways, and Saddle Dam. main is expected to be 145 m high 1780 long. After filling estimated volume water bounded about 74 billion m3. f...

Evaporation is one of the largest water losses from most of the dam lakes in Iran. Estimating the evaporation rate enables us to apply the proper evaporation mitigation technologies. In this study, the feasibility of different evaporation estimation methods was studied to find an optimum method with a fair tradeoff between cost and accuracy. The optimum method may vary depending on the climate....

Large dams and reservoirs alter not only the natural flow regimes of streams rivers but also their flooding cycles flood magnitudes. Although effect has been reported for some vulnerable locations, understanding inner-basin variation with respect to effects remains limited. In this study, we analyse Three Gorges Dam (TGD) built on Changjiang mainstream (Yangtze River) investigate dam variations...

with the aim of identifying the rotifera fauna of kepektas dam lake, samples were collectedmonthly between january-december 2005. in total 11 rotifer species were identified. as a species-wisepercentage, kellicttia longispina had the highest level with 57%. when the annual abundance of species wastaken into consideration polyarthra vulgaris, colurella uncinata, asplanchna priodonta and keratell...

PURPOSE Although multiple serum antiretinal autoantibodies (ARAs) have been reported in patients with paraneoplastic and non-paraneoplastic autoimmune retinopathy ((n)pAIR), not all retinal antigens involved in (n)pAIR are specified. This study aims to serologically identify patients with presumed (n)pAIR through determination of both known and unknown ARAs by autoantibody profiling. METHODS ...
