سیستم اصلی سازگاری بافتی (mhc) به دلیل نقش زیست شناختی وسیع و گسترده آن در سیستم ایمنی بسیار مورد توجه بوده است. آنتی ژن های این مجموعه ژنی که در انسان تحت عنوان آنتی ژن های لکوسیتی انسانی (hla) خوانده می شوند، در پاسخ های ایمنی نقش مهم و در خور توجهی دارند، و ژنوم مربوط به این مجموعه به عنوان ژن های کنترل کننده پاسخ های ایمنی مطرحند. از طرف دیگر رابطه قوی و مستحکم بین پاره ای از بیماری های با ...
This paper deals with the statistical analysis of the uniaxial compressive strength and of the elastic modulus of jointed rock masses under different confining pressures. Properties of the rock masses with different joint fabric, with and without gouge have been considered in the analysis. A large amount of experimental data of jointed rock masses from the literature has been compiled and used ...
background and objectives: to investigate coagulase gene polymorphisms of mrsa and mssa isolates from shiraz teaching hospitals from 2011 to 2012. materials and methods: a total of 302 isolates of staphylococcus aureus were collected from clinical specimens in three major teaching hospitals and confirmed on the basis of morphological characteristics and biochemical tests. the isolates were subj...
background and objectives: bacillus anthracis is one of the most homogenous bacteria ever described. bacillus anthracis 17jb is a laboratory strain. it is broadly used as a challenge strain in guinea pigs for potency test of anthrax vaccine. material and methods: this work describes genetic characterization of b. anthracis 17 jb strain using the snps and mlva genotyping. results and conclusion:...
conclusions sequence and structural diversity of the 3'utr variable region and poly u/uc region found in the local isolates indicate specificity in the regulating elements of 3'utr that might be associated with differential replication efficacy of the hcv pakistani isolates. the study necessitates functional characterization of these regulating elements to elucidate variable viral eff...
conclusions the results of this study showed that pcr–rflp technique was a fast and applicable method especially for separation, detection and differentiation between species of b. melitensis and b. abortus biovars in blood sample. also the presented data showed that b. melitensis biovar 1 was the prevalence biovar. background brucella is an intracellular parasite of the disease brucellosis thr...
سلول های بنیادی جنینی انسانی قابلیت های شگرفی در حوزه ی پزشکی و سلول درمانی دارند. در این راستا، منفرد کردن سلول های بنیادی انسانی با هدف گسترش سریع این سلول ها و انجام دست ورزی های مختلف بر روی آن ها اجتناب ناپذیر است. اما در این فرایند مانعی وجود دارد، بدین معنا که آپوپتوز القا شده در اثر فعالیت مسیر سیگنالی rho/rock که در نتیجه ی منفرد شدن سلول های بنیادی انسانی فعال می شود، کشت و دست ورزی ا...
Background: Negative regulatory mechanisms of ROCK signaling are poorly understood. We have discovered a novel mechanism to attenuate ROCK signaling. Results: Coronin1B is a novel binding partner of ROCK2 that inhibits ROCK signaling to myosin. Conclusion: Coronin1B regulates ROCK by a novel signal attenuation mechanism. Significance: Coronin1B attenuation of ROCK signaling is associated with N...
Rock bolts have been widely used as rock reinforcing members in underground coal mine roadways and tunnels. Failures of rock bolts occur as a result of overloading, corrosion, seismic burst and bad grouting, leading to catastrophic economic and personnel losses. Monitoring the health condition of the rock bolts plays an important role in ensuring the safe operation of underground mines. This wo...
