In order to determining the percentage of staph. carriers which is important in spreading to other patients and thus to the community. This descriptive and cross sectional studv was performed in 3 teaching hospitals of Iran University of Medical Sciences and Health Services. 380 health workers were chosen, separate nasal and pharyngeal swabs were taken from each person and transferred to mannit...
Nanoscaled polymer composites were prepared from polysaccharide chitosan (CS) and Ca-deficient hydroxyapatite (CDHA). CS-CDHA nanocomposites were synthesized by in situ precipitation at pH 9, and the CS-CDHA carriers were then fabricated by ionic cross-linking methods using tripolyphosphate and chemical cross-linking methods by glutaraldehyde and genipin. Certain biomolecules such as vitamin B1...
Background: Helicobacter pylori infection is one of the most common gastrointestinal infections worldwide. Predominant T-helper 1 (Th1) responses with increased gamma interferon (IFN- γ) levels have been proposed to play an important role in H. pylori-induced peptic ulcer. However, bacterial factors contributing to the initiation of Th1 polarization of H. pylori-specific immune responses have n...
scid is a lethal genetic autosomal recessive disorder that has been observed in humans, dogs, mice, and horses. affected animals are incapable of generating specific antigens for immune responses needed to protect them from infectious diseases. the frequency of affected recessive allele varies in different regions so that the outcome of normal breeding with carriers of recessive alleles is diff...
OBJECTIVE Lipoprotein lipase (LPL) exerts 2 principal actions, comprising enzymatic hydrolysis of triglyceride-rich lipoproteins (TRLs) and nonenzymatic ligand capacity for enhancing lipoprotein removal. The common LPLS447X variant has been associated with cardiovascular protection, for which the mechanism is unknown. We therefore evaluated enzymatic and nonenzymatic consequences of this LPL va...
Background and Aim: Thalassemia, a heterogeneous disease, is one of the most common single-gene diseases worldwide. The aim of this study was to find associations between hematological indices and severity of beta-globin gene mutations in beta-thalassemia carriers. Materials and Methods: In this cross-sectional study, 30 beta-goblin gene mutations (b+ and b○) in 1206 unrelated beta-thalassemi...
The aim of this study is to formulate a novel ophthalmic nanosuspension (ONS), an alternative carrier system to traditional colloidal carriers for controlled release (CR) of acyclovir (ACV). In the present study, ONS is employed to avoid some of major disadvantages of colloidal carriers systems such as instability in cul de sac and short half life by increasing efficiency of drug encapsulation ...
The results of a study the galvanomagnetic properties indium arsenide grown by liquid-phase epitaxy are presented. It is shown that use rare earth element holmium in growth InAs epitaxial layers makes it possible to reduce electron concentration two orders magnitude n=2.1·10 15 cm -3 at T=77 K. This effect due gettering shallow background impurities with formation their compounds melt. With an ...
the implementation of economic projects by targeting the subsidies can have a great effect on the costcompetitiveness of the industries and their products. the global steel industry has been considered as a basickey industry in the industrialized countries. it is also among the industries that may be seriously affected by theenforcement of subsidies. this industry, requiring energy and high-tec...
OBJECTIVES To investigate whether serum neurofilament light (NfL) concentration is increased in familial Alzheimer disease (FAD), both pre and post symptom onset, and whether it is associated with markers of disease stage and severity. METHODS We recruited 48 individuals from families with PSEN1 or APP mutations to a cross-sectional study: 18 had symptomatic Alzheimer disease (AD) and 30 were...
