mass vaccination against viral infections such as mumps is a very noticeable and appropriate attempt in common health. mumps infection has severe complications like deafness, infertility and meningitis. attenuated live vaccine of mumps is produced and used to prevent the problems. viral content in the monovalent vaccine is assayed with different methods. nowadays international standards introdu...
Objective: Oxidative stress plays an important role in the onset and progression of diabetic nephropathy. So antioxidant agents may be one of the key treatment strategies for prevention of diabetic nephropathy progression .The aim of this study was to determine the effect of selenium (Se) on micro-albuminuria in type 2 diabetic (T2DM) patients. Materials and Methods: This study was a clinical ...
Abstract Background and objectives: "The comb antibiotic sensitivity test" is a quick, reliable and cost effective method to determine the susceptibility of bacteria to different antibiotics. The purpose of this study is to design a plate that is easy and quick to use, and enable to be interpreted easily without the need for measurement of the margins with a ruler. Material and Method...
This paper investigates damping ratio in micro-beam resonators based on magneto-thermo-elasticity. A unique aspect of the present study is the effect of permanent magnetic field on the stiffness and thermo-elastic damping of the micro resonators. In our modeling the theory of thermo-elasticity with interacting of an externally applied permanent magnetic field is taken into account. Combined the...
objective: in this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. methods: the base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. lorentz electric force, which is used as stimulating flow factor, is created by appl...
abstract: this study was aimed at probiotication of tomato and carrot juices using lactobacillus plantarum, lb. fermentum, lb. casei, lysinibacillus sphaericus and saccharomyces boulardii. to enhance the stability, the probiotic cultures were micro-encapsulated using alginate coated chitosan beads. tomato and carrot juice samples were pasteurized for 20 min at 63 °c. lb. fermentum, lb. plantara...
زمینه و هدف : با افزایش اندازه تومور، محیط سلولهای توموری هیپوکسیک و اسیدیک شده و سلول ها شروع به افزایش تولید چندین نوع عامل رشد میکنند که در نتیجه آن تشکیل رگهای خونی موضعی آغاز میشود. به دنبال آن متاستاز سلول های سرطانی از طریق عروق خونی اتفاق می افتد، لذا مهار رگزایی می تواند روش جدیدی برای درمان سرطان باشد. این مطالعه به منظور آنالیز بیوانفورماتیکی برای پیش بینی میکرو rna های بالقوه مه...
acetonitrile used as a solvent in manufactures and affects to central nervous system from inhalation exposure. the aim of this study was to develop a micro-solid phase extraction method for the determination of acetonitrile in the air matrix. the sampling was performed with a small diameter fused silica fiber coated with a thin film of stationary phase and was subsequently desorbed and analyze...
