AIM To assess at the scansion electron microscope (SEM) the structural aspects of enamel hypoplasia (EH) in coeliac disease (CD) with the aim to investigate our hypothesis of a possible significant difference between structural characteristics of EH in CD affected patients and EH of non-coeliac patients. If the presence of specific features of the EH associated with CD were demonstrated, these ...

سیانور متداول‌ترین بازداشت کننده برای پیریت و اسفالریت در فلوتاسیون سرب است. سیانور با وجود این که بازداشت کننده ای قوی و مؤثر است ترکیبی بسیار سمی و کشنده می‌باشد و استفاده از آن سبب بروز آلودگی‌ها و مخاطرات جدی محیط زیستی می‌شود. در این پژوهش عملکرد سه ماده شیمیایی سدیم سولفید، سدیم متابی‌سولفیت و سدیم سولفیت به عنوان جایگزین سیانور در فلوتاسیون سرب کانسنگ سرب و...

A signature of eclosion hormone (EH) action in insect ecdysis is elevation of cGMP in Inka cells, leading to massive release of ecdysis triggering hormone (ETH) and ecdysis initiation. Although this aspect of EH-induced signal transduction is well known, the receptor mediating this process has not been identified. Here, we describe a receptor guanylyl cyclase BdmGC-1 and its isoform BdmGC-1B in...

Epoxide hydrolases (EC 3.3.2.3) are ubiquitous enzymes that catalyze the hydrolysis of epoxides to the corresponding vicinal diols. More than 100 epoxide hydrolases (EH) have been identified or predicted, and 3 structures are available. Although they catalyze the same chemical reaction, sequence similarity is low. To identify conserved regions, all EHs were aligned. Phylogenetic analysis identi...

Despite its role in monetary policy and finance, the expectations hypothesis (EH) of the term structure of interest rates has received virtually no empirical support. The empirical failure of the EH has been attributed to a variety of econometric biases associated with the single-equation models most often used to test it; however, none of these explanations appears to account for the massives ...

In order to understand the roles of the epoxide hydrolases (EHs) in xenobiotic biotransformation in insects, we examined the induction of EHs by exogenous compounds in Drosophila melanogaster third instar larvae. Among the chemicals tested, clofibrate, a phenoxyacetate hypolipidermics drug, increased EH activity towards cis-stilbene oxide approximately twofold in larval whole-body homogenates. ...

The pathophysiology of primary benign exertional headache (EH) is not still clearly defined. Some researchers have suggested an impaired vascular response as the etiology of this disorder. In this study we investigated whether there are any differences in blood pressure (BP) and heart rate (HR) of the subjects in course of the static and dynamic exercises and the treadmill stress test between t...

Aldosterone synthase (CYP11B2) is closely linked to essential hypertension (EH). However, it remains unclear whether the methylation of the CYP11B2 promoter is involved in the development of EH in humans. Our study is aimed at evaluating the contribution of CYP11B2 promoter methylation to the risk of EH. Methylation levels were measured using pyrosequencing technology in 192 participants in a h...
