در دو دهه اخیر، انتروکوکها مقاومت گستردهای به تعدادی از آنتیبیوتیکها کسب کردهاند که این امر سبب پیچیدگی در درمان عفونتهای ناشی از این باکتریها گردیده است. از آن جایی که گوشت قرمز بهعنوان یک ماده غذایی پر مصرف مورد استفاده در ایران است و به سهولت با این باکتری آلوده میشود بر آن شدیم تا فراوانی ژنهای مقاومت آنتیبیوتیکی درجدایههای انتروکوکوس فکالیس جدا شده از گوشت قرم...
Background: This study aimed to investigate the occurrence of aminoglycoside resistance and the prevalence of the resistance-modifying enzyme genes, ant(3”)-III, ant(6’)-Ia, aac(6′)-Ie-aph(2”)-Ia, and aph(2’)-Id, in Enterococcus strains isolated in Kermanshah Province, west of Iran.Methods: In this cross-sectional study, 108 enterococcal isolates from urine, wound, blood, and cerebrospinal flui...
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...
Different isoforms of the adenine nucleotide translocase (ANT) are expressed in a tissue-specific manner. It was assumed that ANT-1 and ANT-2 co-exist in every single mitochondrion and might be differently distributed within the membrane structures that constitute the peripheral inner membrane or the crista membrane. To discriminate between ANT originating from peripheral or from cristal inner ...
Platforms with low radar signatures require compatible antennas (low scattering) for communication purposes. Under this context, the article presents two Fabry-Perot (FP) Cavity (Ant-1 and Ant-2). Ant-1's aperture is an integrated design of artificial magnetic conductor (AMC) surface a phase gradient metasurface (PGM), incorporating three unit-cell structures. The antenna achieves reduced monos...
هدف: استافیلوکوکوس اورئوس مقاوم به متی سیلین یکی از عوامل اصلی عفونت های بیمارستانی و اکتسابی از جامعه است. آمینوگلیکوزیدها عوامل باکتریسیدال قدرتمندی هستند که اغلب به صورت ترکیبی همراه با بتالاکتام ها یا گلیکوپپتید ها به خصوص در درمان اندوکاردیت استافیلوکوکی مصرف می شوند. غیرفعال سازی آنزیمی دارو توسط آنزیم های سلولی تغییردهنده آمینوگلیکوزیدها، اصلی ترین مکانیسم مقاومت به این داروها در استافیل...
Background: In recent years, three new aminoglycoside resistance genes such as aph (3ʹ)-IIIa and ant (4ʹ)-Ia, that encode for the APH (3ʹ) and ANT (4ʹ) have also been identified. The aim of this study was to come up with a multiplex-PCR procedure for detection of aac(6ʹ)-Ie–aph(2ʹʹ)-Ia, aph(3ʹ)-IIIa, ant(4ʹ)-Ia genes in the Enterococcus spp. clinical isolates. Material and Method: 100 ...
Bcl-2 is a prosurvival factor that reportedly prevents the nonspecific permeabilization of mitochondrial membranes, yet enhances specific ADP/ATP exchange by these organelles. Here, we show that Bcl-2 enhances the ADP/ATP exchange in proteoliposomes containing the purified adenine nucleotide translocase (ANT) in isolated mitochondria and mitoplasts, as well as in intact cells in which mitochond...
Solenopsis invicta virus 2 (SINV-2) is the second virus identified from the fire ant, S. invicta Buren. SINV-2 is unique among positive-strand RNA viruses from insects by possessing four cistrons in a monopartite genome. Fire ant colonies testing positive for SINV-2 by RT-PCR did not exhibit any discernable symptoms. RT-PCR-based surveys for SINV-2 among 688 fire ant mounds in Alachua County, F...
AntWars is a competitive two-player game with local information that was introduced as part of a competition accompanying the Genetic and Evolutionary Computation Conference 2007 [1,3]. Both players control an ant in a toroidal world and have to collect randomly placed pieces of food. The player who collects more food wins. 2-AntWars is an extension of AntWars. In 2-AntWars, each player control...
