زمینه و هدف : انتروکوکها باکتریهای گرم مثبتی هستند که در دستگاه گوارش انسان یافت میشوند. عفونتهای بیمارستانی و مقاومت آنتیبیوتیکی سبب افزایش اهمیت انتروکوکها شده است. این مطالعه به منظور ارزیابی مولکولی ژنهای van A و van B در جدایههای انتروکوکی بیمارستانی مقاوم به ونکومایسین و تیکوپلانین با استفاده از روش مولکولی PCR انجام شد. روش بررسی : در این مطالعه توصیفی 113 جدایه از بخشهای مختلف ...
background cutis marmorata telangiectatica congenita (cmtc) is a sporadic congenital skin vascular abnormality. significant number of patients has other congenital anomalies. case report we report a case of a preterm male newborn with cutis marmorata pattern presented on the skin of the face, right side of front of the trunk, whole back, glutei and both legs. besides, microretrognatia and asymm...
In this study a simple, highly sensitive, and selective electrochemical method was developed for determination of the low concentration curcumin (CUR) using a poly(vanillin-co-caffeic acid) p(Van-CA) modified platinum electrode. Electrode modification was carried out electrochemically with cyclic voltammetry (CV) method. For this purpose; a solution of 6 mM vanillin (Van) and 6 mM caff...
Reaction behaviors and kinetics of catalytic oxidation of toluene with different feed flows over Pt/Zr(x)-HMS catalysts with Si/Zr ratio equal to 5, 10, 20 and 35 were investigated over a wide temperature range (200 – 500 oC). Results show that Pt/Zr(x)-HMS performs more easily toluene oxidation. The kinetic data were fitted by the Power-law and Mars–van Krevelen kinetic models. The fitting res...
In this paper, we calculate the second virial coefficient for binary mixtures of Ar with CH4 and CO in order to evaluate the performance of equations of state (EOSs). The investigated EOSs are van der Waals (vdW), Redlich-Kwong (RK), Peng-Robinson (PR), Carnahan-Starling–van der Waals (CS-vdW) and Guggenheim-van der Waals (G-vdW) based on van der Waals model. In our work, we also use Dieterici ...
ellis-van creveld sydrome (chondroectodermal dysplasia) is a hereditary form of short limb disproportionate dwarfism characterized by diffuse involvement of skeletal system and visceral organs. two brothers affected by this syndrome are presented here following a brief account of the disease's manifestations.
ellis-van creveld syndrome is a very rare autosomal recessive skeletal dysplasia characterized by a short stature, short limbs, short ribs, postaxial polydactyly, dysplastic nails, multiple frenula, and congenital heart defects. we describe a 22-year-old boy with a short stature, short limbs, short distal extremities, small teeth, short upper lip bound by frenula to the alveolar ridge, multipl...
background: bacteremia due to enterococcus faecalis is usually caused by strains resistant to most antibiotics. effective management of the disease is dependent on rapid detection and characterization of the bacteria, and determination its sensitivity pattern to antimicrobial drugs. the aim of this study was to investigate a more rapid and reliable assay for simultaneous diagnosis of enterococc...
damage to essential facilities (e.g. lifelines and industrial facilities) due to extreme loads may cause remarkable indirect impact as well as direct physical loss. hence understanding seismic performance of essential facilities is very important in high seismic risk regions. on october 23, 2011 an earthquake of magnitude mw7.2 occurred in van province in eastern turkey. several damages occurre...
