The hyperactivity of the brain renin-angiotensin system (RAS) has been implicated in the development and maintenance of hypertension in several types of experimental and genetic hypertension animal models. We previously reported that in the murine brain, aminopeptidase A (APA) is involved in the conversion of angiotensin II (AngII) to AngIII and that AngIII is one of the main effector peptides ...

Polyadenylation [poly(A)] of mRNA is a critical step during gene expression, which plays an important role in the termination of transcription. Prediction of poly(A) sites can help identify 3' ends of genes and improve genome annotation. Due to the limited knowledge of poly(A) signals in plants, predictive modeling of poly(A) sites in agricultural crops remains challenging. Recent studies have ...

Background In children less than 3 years of age, there is little experience in the nonoperative management of appendiceal phlegmon or abscess (APA), especially in APA with an appendicolith. The purposes of this study were to evaluate the effects of an appendicolith and the success rate of nonoperative management for APA in these young children. Methods Children younger than 3 years of age wit...

We investigated the consequences of a progressive damage to the muscular system on the organization of anticipatory postural adjustments (APA) in children with Duchenne muscular dystrophy (DMD). We used a bimanual load-lifting task requiring the stabilization of the forearm position despite its voluntary or imposed unloading. Eight children with DMD from 4 to 11 years of age were compared to ei...

In cancer cells, genetic alterations can activate proto-oncogenes, thereby contributing to tumorigenesis. However, the protein products of oncogenes are sometimes overexpressed without alteration of the proto-oncogene. Helping to explain this phenomenon, we found that when compared to similarly proliferating nontransformed cell lines, cancer cell lines often expressed substantial amounts of mRN...

Alternative polyadenylation (APA) is an important regulatory mechanism of gene functions in many biological processes. However, the extent of 3' UTR variation and the function of APA during the innate antiviral immune response are unclear. Here, we show genome-wide poly(A) sites switch and average 3' UTR length shortens gradually in response to vesicular stomatitis virus (VSV) infection in macr...

Primary aldosteronism (PA) is characterized by hypertension and suppressed renin activity with or without hypokalemia and comprises the aldosterone-producing adenoma (APA) and bilateral adrenal hyperplasia or idiopatic hyperaldosteronism (IHA). In recent series employing the aldosterone (aldo, ng/dL):renin (ng/mL.h) ratio (ARR) for screening, prevalence of PA among hypertensives soars to 8-20%;...

OBJECTIVE Primary aldosteronism (PA) due to aldosterone-producing adenoma (APA) is the most common curable form of secondary hypertension. DESIGN In order to evaluate blood pressure outcome after adrenalectomy for APA and to identify new favorable prognostic factors, data from 42 consecutive APA patients who underwent adrenalectomy were collected from 2005 to 2007. METHODS Renin-angiotensin...

aflatoxin contamination of food and feedstuffs is a serious economic and health hazard. over a period of two years, 35 samples of raw pistachio nuts collected from different parts of iran were analysed for the presence of aflatoxigenic strains of the aspergillus flavus group. eighty-five isolates of a.flavus and a.parasiticuswere identified based on specific yello-orange pigment production in t...
