Background: Follicle stimulating hormone is a heterodimeric protein composed of two subunits, α and ß, which are linked noncovalently. The hypophysial gonadotropin FSH plays an important role in the regulation of oocyte maturation, and a key component for growth of ovulator follicles in ewes. Materials and Methods: This study seeks to clone and express the ovine follicle stimulating hormone sub...
Background and Objective: P53 is a suppressive gene that plays a key role in DNA repair and apoptosis. The purpose of this study was to investigate the effect of P53 protein over-expression and some clinicopathological factors on the esophageal squamous cell carcinoma (SCC) response to neoadjuvant chemoradiotherapy. Patients and Methods: In this retrospective cohort study, 44 patients with loc...
materials and methods the expression of gp73 was investigated in 88 cancerous and self-control non-cancerous tissues using tissue microarrays with immunohisto- chemistry and was confirmed by western blotting. circulating gp73 levels were detected in the sera of 281 patients with liver diseases using enzyme-linked immunosorbent assay. results the levels of circulating gp73 expression in the hcc ...
چکیده: در این رساله ابتدا مفهوم c*-جبر را بیان می کنیم سپس با تجزیه وتحلیل دقیق مقاله های on frames in hilbert modules over pro-c*-algebras, projections on hilbert modules over locally c*-algebras. مفهوم c*-جبر موضعی و قاب ضربگرها در مدول های هیلبرت روی c*-جبرموضعی بیان می شود و نشان می دهیم برخی از ویژگیهای قابها در c*-مدول های هیلبرت برای قاب ضربگرها در مدول های هیلبرت روی c*-جبرموض...
A novel strategy to increase protein expression yield is unintended induction of expression in complex media, called auto-induction. This method can be used to express proteins under control of the lac promoter without any need to monitor bacterial growth pattern, and addition of specific expression inducers such as Isopropyl β-D-1-thiogalactopyranoside (IPTG) at proper time. In the present stu...
less than 5% of prenatal thymoctes express hla-dr before week 12 of gestation. however, the number of hla-dr- positive cells increases during the late second and third trimesters of development. to determine the role of alpha-smooth muscle actin in fetal thymic hla-dr signaling in different stages of development we examined and compared the immunohistochemical expression of alpha-smooth muscle ...
The visual system groups similar features, objects, and motion (e.g., Gestalt grouping). Recent work suggests that the computation underlying perceptual grouping may be one of summary statistical representation. Summary representation occurs for low-level features, such as size, motion, and position, and even for high level stimuli, including faces; for example, observers accurately perceive th...
systemic lupus erythemathosus is an autoimmune disease that affected many various types of tissues in 10% of world population and over 30 genes has associated with it. nouroimmunoendocrynology concepts have shown that immune system could be affected by neuron system and vice versa, 5-hydroxytryptamine receptor a (5ht3ra) was studied as a main receptor in these relations. in this study, peripher...
بمنظور پی بردن به چگونگی مناسبات احتمالی میان خصوصیات شخصیتی با موفقیت تحصیلی و گزینش دانشکده، فرم فارسی آزمون شخصیتی لنیون به 178 نفر دانشجوی پسر و دختر سال دوم دانشکده های گوناگون دانشگاه شیراز و 346 نفر دانش آموز پسر و دختر کلاسهای ششم مدارس نواحی مختلف شهر شیراز داده شد. نتایج حاصله نشان داد که : 1 - در مورد پسرهای دانشجو همبستگی مثبت معنی داری بین عامل شخصیتی alienation و موفقیت تحصیلی وجو...
Introduction: Overexpression of Human Epidermal Growth factor Receptor-2 (HER-2) is one of the most important prognostic and predictive factors of breast cancer, observed in 25% - 30% of breast carcinoma patients leading to poor prognosis and feasible anti HER-2 antibody drugs. The objective of this study was to evaluate the HER-2 frequency in target population and its correlat...
