background: opioid peptides and their receptors are present in the majority of body tissues including gastrointestinal tract. heroin is one of the opioid derivatives that abuse increasingly today. so far, there is no study on the effect of acute heroin administration on gastric acid and pepsin secretion. objective: to define the effect of the acute heroin consumption on basal and vagal-sti...
Abstract Background and Objective: The Isolation of Nocardia species is complex and time-consuming, which is due to rapid growth of adjacent bacteria. Because of the importance of a specific medium with the ability of controlling intrusive microorganisms, this study aimed at comparing three laboratory methods to introduce the reliable isolation technique for Nocardia species. Material and Met...
Streptokinase is one of the best known thrombolytic agents with widespread clinical use. However, its use is not risk-free due to its immunogenicity, hemorrhagic complications and relatively short half-life in circulation. Specific PEGylation of cysteine residue is a useful technique for reducing most of these complications. The aim of this study was designing and producing a cysteine containin...
noise is considered as one of the most severe sources of environmental and work place constraints. noise effects on immune function, hormonal levels, cardiovascular and respiratory systems are well known. the aim of the study is to evaluate the effects of traffic noise on basal and stimulated gastric acid secretion. 48 healthy rats were divided into five traffic noise exposures (1, 7, 14, 21, 2...
When the picrosirius red technique was applied to cardiac muscle sections, intense yellow myocyte staining sometimes obscured thin collagenous septa. The picrosirius red technique was modified to include treatment of the sections in 0.2% (w/v) aqueous phosphomolybdic acid prior to staining. With 1-5 min treatment, cytoplasmic staining was eradicated; diminution of collagen staining occurred onl...
The biosynthetic pathways of saturated and unsaturated fatty acids consist of many steps controlled by various enzymes. One of the methods for improving oil quality is to change the fatty acid profile through genetic manipulation which requires isolation and characterization of the genes and other cis-acting elements, such as the promoter, involved in fatty acid biosynthesis. b-ketoacyl-CoA syn...
Objective(s): The aim of present study is to formulate mefenamic acid transdermal gel based on vesicular drug delivery approaches.Materials and Methods: For the preparation of mefenamic acid transdermal gel, transfersomes were selected as colloidal carriers. Transfersomes were prepared by hand shaking and thin film hydration techniques. The obtained transfersomes were characterized for vesicula...
Background & Aims: Folic acid is one of the important hematopoietic agents necessary for proper regeneration of the blood forming elements and their functioning. Since humans cannot synthesize folates, they must be obtained from dietary sources. The most important dietary sources of folates are fortified foods and cereal products with folate content of 50-200 μg/100 g. In Iran the majority of ...
Background: Opioid peptides and their receptors are present in the majority of body tissues including gastrointestinal tract. Heroin is one of the opioid derivatives that abuse increasingly today. So far, there is no study on the effect of acute heroin administration on gastric acid and pepsin secretion. Objective: To define the effect of the acute heroin consumption on basal and vagal-stimu...
In this report, the degradation of 1-Naphthol was studied under xenon irradiation for 2 h using WO3-rGO nanocomposite as photocatalyst. Raman spectroscopy and scanning electron microscopy demonstrated nanocomposite formation. Gas chromatography-mass spectrometry (GC-MS) technique which was utilized to analyze the degradation products, confirmed the formation of salicylic acid as a...
