The microbes that inhabit the human oral cavity are subjected to constant fluctuations in their environment. To overcome these challenges and gain a competitive advantage, oral streptococci employ numerous adaptive strategies, many of which appear to be intertwined with the development of genetic competence. Here, we demonstrate that the regulatory circuits that control development of competenc...
Background and purpose: Brucellosis is a systemic infection caused by gram-negative coccobacilli and facultative intracellular bacteria of the genus Brucella. Interleukin-17 is one of the important cytokines that plays a role in controlling host immune response in patients with brucellosis. The aim of this study was to investigate polymorphism of the genes encoding IL-17 in patients with brucel...
Background and purpose: Melatonin is a well-known neuroendocrine reproductive hormone-based hormone that has an important role in the circadian clock system and has potent antioxidant properties. New studies have also suggested an antitumor role for melatonin. The role of melatonin receptors is proven in many cancers, including colon and breast cancers, but so far, no study has been performed i...
The production of (p)ppGpp by Streptococcus mutans UA159 is catalyzed by three gene products: RelA, RelP, and RelQ. Here, we investigate the role of the RelA (Rel) homologue of S. mutans in the stringent response and in the global control of gene expression. RelA of S. mutans was shown to synthesize pppGpp in vitro from GTP and ATP in the absence of added ribosomes, as well as in vivo in an Esc...
مقدمه و هدف: لیشمانیوز یکی از مهمترین بیماری های عفونی جهان می باشد. این بیماری در بیش از نیمی از استان های ایران به عنوان مشکل بهداشتی مطرح می باشد. تشخیص مخازن بیماری و همچنین تعیین هویت نوع انگل در انسان در شناسایی جنبه های اپیدمیولوژیک بیماری وارائه برنامه کنترل اهمیت زیادی دارد. روش کار: این مطالعه توصیفی در سال 1387 با استفاده از تکنیک pcr-rflp در شهرستان دامغان انجام شده است. بررسی بر رو...

با توجه به پراکندگی جغرافیایی سیکل سل در نقشه جهانی و قرار گرفتن کشورهای مجاور (عربستان سعودی، کویت ، بحرین، ترکیه و هندوستان) در کمربند این بیماری، این طرح برای اولین بار در ایران، از میان اختلالات هموگلوبین، به هموگلوبینوپاتی سیکل سل پرداخته است . اهداف مورد نظر در طرح عبارت بودند از: -1 ارزیابی لزوم غربالگری ناقلین سیکل سل در ایران، در کنار برنامه های پیشگیری از تالاسمی که در دست اجرا است . ...
An experimental study for air-side thennal-hydraulic performance of brazed aluminum heat exchangers under dehumidifYing conditions has been performed. For 30 samples of louvered fin heat exchangers with different geometrical parameters, the heat transfer and pressure drop characteristics for wet surface were evaluated. The test was conducted for air-side Reynolds number in the range of 80-300 a...
The presence of uninterpreted symbols in the logic means that we must distinguish between a state machine M and its abstract description D in the logic. A given abstract description D will determine a machine M for every interpretation ¢. For the purpose of hardware verification we are interested only in finite state machines (FSMs). However, an abstract description will represent infinite as w...
