BACKGROUND It is controversial whether angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB) provide significant survival benefits in patients with coronary artery disease (CAD) but without myocardial infarction (MI). This study investigated whether the association of ACEI/ARB therapy with clinical outcome in patients undergoing percutaneous coronary intervention (...
This paper was prepared as the result of work sponsored by the California Air Resources Board (ARB) and the California Environmental Protection Agency (Cal/EPA). It does not necessarily represent the views of the California Energy Commission, ARB, Cal/EPA, their employees, or the State of California. The Energy Commission, ARB, Cal/EPA, the State of California, their employees, contractors, and...
Metaphase and anaphase spindles in cultured newt and PtK1 cells were irradiated with a UV microbeam (285 nM), creating areas of reduced birefringence (ARBs) in 3 s that selectively either severed a few fibers or cut across the half spindle. In either case, the birefringence at the polewards edge of the ARB rapidly faded polewards, while it remained fairly constant at the other, kinetochore edge...
Angiotensin II (A-II) receptor (AT(1) receptor) blockers (ARB) are a class of antihypertensive agent. It is known that they suppress signal transduction pathways mediated by growth factors [e.g., epidermal growth factor (EGF)] through the AT(1) receptor in vascular endothelial cells. In the present study, we demonstrated that A-II activates the cell proliferation of prostate cancer as well as E...
In this paper, an extended accumulative roll bonding (ARB) technique, called the 'Four-Layer Accumulative Roll Bonding (FL-ARB)' technique, is presented for the first time. This technique has been employed to produce ultrafine-grained commercial pure aluminum sheets with success. After three FL-ARB passes, the grain size of pure aluminum was seen to reduce to 380 nm. The bonding strength of the...
BACKGROUND Both angiotensin II type I receptor blockers (ARBs) and calcium channel blockers (CCBs) are widely used antihypertensive drugs. Many clinical studies have demonstrated and compared the organ-protection effects and adverse events of these drugs. However, few large-scale studies have focused on the effect of these drugs as monotherapy on laboratory parameters. We evaluated and compared...
This paper introduces the DUP System, a simple framework for parallel stream processing. The DUP System enables developers to compose applications from stages written in almost any programming language and to run distributed streaming applications across all POSIXcompatible platforms. Parallel applications written with the DUP System do not suffer from many of the problems that exist in traditi...
کامپوزیت های زمینه فلزی با داشتن نسبت استحکام به وزن بالا، سختی مناسب و مقاومت به سایش خوب در صنایع گوناگون، بسیار مورد توجه قرار گرفته اند. پیدایش شیشه های فلزی و استفاده از آن ها به عنوان تقویت کننده نسبت به سایر تقویت کننده ها به ویژه تقویت کننده های سرامیکی، در چند سال اخیر مورد توجه محققان قرار گرفته است. در این تحقیق نانو کامپوزیت های زمینه آلومینیومی تقویت شده با ذرات شیشه های فلزی با تر...
در این پژوهش فرایند نورد ساندویچی و معمولی نوعی ورق نازک فولادی با لایه های آلومینیومی، بررسی و مقایسه شده است. ورق از جنس فولاد ضدزنگ sus304 و لایه های آلومینیومی از جنس آلومینیوم 1050 است. هر دو روش نورد به روش المان محدود با رفتار مکانیکی کرنش سخت تحلیل و سپس با استفاده از نتایج تجربی، صحت سنجی شده است. هم چنین دو روش نورد از لحاظ توزیع کرنش، فشار، نیرو و گشتاور لازم مقایسه و اثر درصد تغیی...
