Background: Endometriosis is the presence of endometrium- like tissue in sites outside the uterine cavity, primarily on the pelvic peritoneum and ovaries. Ectopic endometrium for replacement and growth require to blood supply. Vascular endothelial growth factor (VEGF) is one of the most important intermediate of locality angiogenesis that product by monocytes and macrophages. This study evaluat...
آنژیوژنز در بسیاری از شرایط پاتولوژیک همچون رشد تومور، متاستاز، رتینوپاتی دیابتی، روماتوئید آرتریت و پسوریازیس نقشی کلیدی ایفا می کند. از میان تمامی فاکتورهای آنژیوژنیک، فاکتور رشد اندوتلیال رگی (vegf) مهمترین فاکتور آنژیوژنز محسوب می شود و فعالیت آن از طریق اتصال به دو گیرنده تیروزین کینازی به نام های گیرنده flt-1 (vegfr-1) و گیرنده kdr (vegfr-2) انجام می شود. هومودایمر vegf از طریق اتصال به v...
Background and Objective: Vascular endothelial growth factor (VEGF) and its receptors (VEGF-R1 and R2) are major regulators of angiogenesis. This study was designed to assess serum levels of VEGF and VEGF-R1 and their prognostic significance in newly diagnosed childhood acute leukemia. Materials and Methods: For this purpose, VEGF and VEGF-R1 were determined using enzyme linked immuno-sorba...
Background: Psoriasis is a chronic disease with multiple biochemical and vascular abnormalities. Several studies have evaluated circulating levels of vascular endothelial growth factor (VEGF) in psoriasis, but none of them evaluated it after reaching a PASI-75 response, as a practical treatment goal. The aim of this study was to evaluate serum levels of VEGF in moderate to severe psoriatic pati...
background and objective: vascular endothelial growth factor (vegf) and its receptors (vegf-r1 and r2) are major regulators of angiogenesis. this study was designed to assess serum levels of vegf and vegf-r1 and their prognostic significance in newly diagnosed childhood acute leukemia. materials and methods: for this purpose, vegf and vegf-r1 were determined using enzyme linked immuno-sorbant a...
Background and Objective: Alzheimer’s disease (AD) is a progressive neurodegenerative disorder, in which cortical and hippocampus neurons death is the main target of neurodegeneration. In addition to extracellular beta amyloid accumulation and the production of neural tangles, one of effective factors in the pathology of Alzheimer's disease is vascular injury in the elderly including disturbanc...
Background: According to the possible role of Vascular Endothelial Growth Factor (VEGF) in the incidence of oral lichen planus lesions, it seems necessary to evaluate it in patients with Oral Lichen Planus (OLP). Objective: The present study aims to investigate the level of VEGF in patients with OLP. Methods: In this systematic review and meta-analysis study, the search was conducted in online...
statement of problem: recurrent aphthous stomatitis (ras) is one of the most common inflammatory diseases encountered in dental practice, but the precise etiology and pathogenesis of the disease is not fully understood. vascular endothelial growth factor (vegf) is a multifunctional angiogenic cytokine involved in angiogenesis and wound healing. there is evidence that vegf could play an importan...
از جمله سازگاری‌های مهمی که در پی تمرینات ورزشی رخ می‌دهد، افزایش چگالی مویرگی یا آنژیوژنز است. فاکتور رشد آندوتلیال عروقی (VEGF) نقش میتوژنیک برای سلول‌های آندوتلیال دارد و واسطۀ مهمی در فرایند آنژیوژنز به‌شمار می‌رود. هدف از تحقیق حاضر، مقایسۀ تأثیر دو نوع فعالیت بدنی بر پاسخ VEGF-A سرمی در مردان غیر‌ورزشکار بود. به همین منظور 11 مرد غیر‌ورزشکار (میانگین سنی80/23 سال) به‌صورت داوطلبانه انت...
background :chronic obstructive pulmonary disease (copd) is a third leading cause of death. methods : in this case control study, we prepared 5 cc bloods from the antecubital vein of 100 copd patients and 40 healthy individuals as control group. vascular endothelial growth factor (vegf) expression protein level was measured by elisa in both groups. results : we found that concentration of v...
