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...
vascular endothelial growth factor (vegf) is a multifunctional cytokine with distinct functions in angiogenesis, lymphangiogenesis, vascular permeability, and hematopoiesis. vegf is a highly conserved, disulfide-bonded dimeric glycoprotein of 34 to 45 kda produced by several cell types including fibroblasts, neutrophils, endothelial cells, and peripheral blood mononuclear cells, particularly t ...
background and objective: vascular endothelial growth factor (vegf) is a cytokine which is overexpressed in many malignant cancers including leukemia. vegf plays an important role in tumor invasion and metastasis. determination of the pattern of vegf expression in human leukemic cell lines could be useful not only in screening of new antileukemic agents but also to study the mechanism of their ...
preeclampsia is an important pregnancy disorder with serious maternal and fetal complications which its etiology has not been completely understood yet. early diagnosis and management of disease could reduce its potential side effects. the vascular endothelial growth factor (vegf) family including vegf-a is the most potent endothelial growth factor which induces angiogenesis and endothelial cel...
چکیده فارسی : رتینوپاتی دیابتی یکی از عوارض شایع میکروواسکولار در بیماران دیابتی است که یکی از عوامل مهم نابینایی در جهان محسوب می شود. vascular endothelial growth factorبه عنوان یک فاکتور آنژیوژنز قوی و هم چنین فاکتور نفوذپذیری عروق نقش مهمی را در ایجاد عوارض دیابت ایفا می کند. در تحقیق حاضر dna جدا شده از 200 بیمار دارای دیابت انجام شد که 101 نفر از آن ها دارای رتینوپاتی دیابتی (dr) و 99...
Objectives: Vascular endothelial cells play an important role in the regulation of vascular vessels with active substances, such as vascular endothelial growth factor are responsible. The present study tried to investigate the effect of resistance training on the density of old women’s endothelial growth factor. Methods & Materials: Twenty-four postmenopausal women (age Mean&...
Introduction: Odontogenic cysts are osteodestructive lesions affecting the jaws. Odontogenic keratocyst is an odontogenic cyst with highly aggressive features. Multicystic ameloblastoma is a benign epithelial odontogenic tumor with more aggressive behavior than dentigerous cyst and odontogenic keratocyst. Invasion and metastasis of tumors require increased blood vessels during tumorigenesis. Th...
background: new blood vessels formation is a critical step in tumor progression. vascular density affects the clinical outcome and prognosis of malignant tumors. the aim of this study was to investigate the relation between the vascular endothelial growth factor (vegf) expression and vascular density with the clinical and histopathologic features in oral squamous cell carcinoma (oscc). method...
uncontrolled hypertension is well- known to give rise to systemic complications involving multiple central organs. artherosclerosis leads to damage of the retinal vessels wall, contributing to venous stasis, thrombosis and finally, occlusion. retinal vein occlusions compromise vision through development of ischaemic maculopathy, macular oedema, and rubeotic glaucoma. laser photocoagulation rema...
objective(s):every year, a large number of people lose their lives due to stroke. stroke is the second leading cause of death worldwide. surprisingly, recent studies have shown that preconditioning with hyperoxia (ho) increases tissue tolerance to ischemia, ultimately reducing damages caused by stroke. addressed in this study are beneficial contributions from ho preconditioning into reduced har...
