Background and purpose: Escherichia coli is the most prevalent etiologic agent of urinary tract infection. Enzymatic inactivation of aminoglycosides by aminoglycoside-modifying enzymes is the main mechanism of resistance to these antibiotics in E. coli. The aim of this study was detecting the ant(2′′)-Ia gene among aminoglycoside resistant clinical isolates of E. coli using PCR method. Materia...
Background: Hypercholesterolemia is considered a major risk factor for pancreatitis, atherosclerosis and coronary heart disease. Cholesteryl ester transfer protein gene polymorphisms are known to be associated with changes in lipid levels. We investigated the association between a polymorphism in the CETP gene (D442G) with plasma lipid levels and CETP activity in patients with hypercholesterole...
Sjogren syndrome is one of the autoimmune diseases which is characterized by lymphocytic infiltration to exocrine glands and causes keratoconjunctivitis sicca and xerostomia. Today, a large population, with a majority of women over 40, suffer from this disease and have several complications regarding oral health and reduced life quality such as severe dental caries, painful eyes, olfactory and ...
مطالعات انجام شده روی مکانیسمهای تکوینی و تکاملی گلبولهای قرمز منجر به دستیابی بشر به مفاهیم پایه و مهمی در ارتباط با مکانیسمهای عمومی تنظیم بیان ژن وشکل گیری بافتها شده است. تمایز اختصاصی به رده ارتیروئید و هر رده دیگری، شدیداً وابسته به تنظیم در سطح بیان ژن و فاکتورهای کنترلی خاص نظیر سیتوکین ها، فاکتورهای نسخه برداری ویژه، عناصر کنترل کننده چرخه سلولی، تکثیر،آپوپتوز و عناصر سیگنالینگ داخل سلو...

cell expansion and cell division are two main processes in plant growth and development. expansin proteins play a role key in cell expansion. these non-enzyme proteins involve in many growth and developmental processes. this protein affects drought tolerance. atexpb2 gene belongs to these proteins family. atexpb2 gene mainly expresses in the root tissue. in this study the expb2 gene, that was i...
The development of efficient and safe carrier system to transfer DNA into cells is essential in non-viral gene therapy. The aim of the present study was to evaluate the effect of linear polyetheneimine (lPEI) (2500 Da) on the physicochemical and biological properties of lipopolyplexes constructed from liposomes and lPEI. Materials and Methods Different lipopolymers were synthesized from lPEI ...
