Angiotensin tachyphylaxis is rapidly induced in the mesenteric vascular circuit of the rat perfused with a saline solution. There is crossed tachyphylaxis among angiotensins (AI, AH, and AIII). The angiotensin antagonist Sar 1-Ileu 8-AII is ineffective when the vascular preparation is previously rendered tachyphylactic to All, showing that the AH receptors are not available during tachyphylaxis...

BACKGROUND Atherosclerosis is a complex, chronic disease that usually arises from the converging action of several pathogenic processes, including hypertension, hyperlipidemia, obesity, and the accumulation of oxidized LDL. Platelet-activating factor acetylhydrolase (PAF-AH) is a LDL- and HDL-bound enzyme that hydrolyzes and inactivates PAF and prevents LDL-cholesterol oxidation, thus delaying ...

Infertility patients are known to be at increased risk of endometrial carcinoma (EC) and atypical hyperplasia (AH). However, the incidence and clinical features of EC and AH in these patients remain to be clarified. In this study, we examined the rate at which a routine infertility workup revealed EC/AH and investigated the clinicopathological features of EC/AH detected in this way. Among patie...

OBJECTIVE The goal of this study was to ascertain optimal assisted hatching (AH) method in frozen embryo transfer. We compared the effect of depending on whether mechanical or laser-AH was performed before or after the vitrification of embryo development rate and blastocyst cell numbers. METHODS In order to induce superovulation, pregnant mare's serum gonadotropin followed by human chorionic ...

The purpose of this clinical practice update is to review diagnostic criteria for severe acute alcoholic hepatitis and to determine the current best practices for this life-threatening condition. The best practices in this review are based on clinical trials, systematic reviews including meta-analysis and expert opinion to develop an approach to diagnosis and management. Best Practice Advice 1:...

Mean dimension for AH-algebras with diagonal maps is introduced. It is shown that if a simple unital AH-algebra with diagonal maps has mean dimension zero, then it has strict comparison on positive elements. In particular, the strict order on projections is determined by traces. Moreover, a lower bound of the mean dimension is given in term of Toms’ comparison radius. Using classification resul...

Background: Arterial hypertension (AH) manifested during childhood and teenage years has been considered, for a long period of time, as being a rare disease and almost exclusively a secondary one. Within the last 10-15 years, as the diagnosis techniques improved and the research regarding juvenile AH extended, the diagnosis criteria have been reconsidered and as a consequence, the disease has b...

The optimal roughage concentration required in feedlot diets changes continuously for many reasons such as source, availability, price, and interaction with other ingredients in the diet. Wet distillers grains and solubles (WDGS) are common in finishing diets and they contain relatively high amounts of fiber compared with other grains they replace. Therefore, concentration of roughage could be ...

Let AH be the real linear space of all Hermitian elements in A . Now AH = A+−A+; in a natural way AH is an ordered topological vector space with positive cone A+ (see [3], [6], [8]). The cone of all positive linear forms on AH will be denoted by P . Restriction of a positive linear form on A to AH gives an element ∗Work done as a student at the University of Groningen (the Netherlands). Receive...

AIM Adenoidal hypertrophy (AH) in children is associated with obstructive manifestations like mouth breathing, snoring. Unfortunately, little is known regarding sleep architecture of AH in children. The purpose of this study was therefore undertaken to investigate the polysomnographic variables in children with AH. METHOD 47 children with AH and 11 controls underwent nocturnal polysomnography...
