Introdution: Targeting vascular endothelial growth factor (VEGF) is considered as a therapeutic goal in solid tumors; especially breast cancer. The use of drugs with natural compounds in the treatment of cancer is increasing because of exerting no adverse effects in normal cells. Crocin, as the main component of saffron, has been proved to have different biological activities on various types o...
Background: Pancreatic islet transplantation has emerged as a promising treatment for type I diabetes. However, its efficacy is severely hampered due to poor islet engraftment and revascularization, which have been resulted to partially loss of transplanted islets. It has been shown that local delivery of vascular endothelial growth factor (VEGF) could accelerate transplanted islet revasculari...
Background & Aim: Retinoblastoma is the most frequent intra-ocular tumor in childhood. The tumor has both endophytic and exophytic patterns of growth. After enucleation, the pathologist is called on to evaluate risk of further growth for prophylactic therapy. Invasion of the choroid or optic nerve are risk factors for developing metastases, but occasionally, metastatic or locally invasive t...
امروزه، سنتز cdnaی ژن های مختلف به طور گسترده در حوزه ی بیوتکنولوژی مطرح بوده و به دلیل کاربردهای زیاد cdna روش های متعددی برای رسیدن به این هدف پیشنهاد شده است. در ارتباط با بسیاری از ژن ها، همواره نیاز به یک روش ساده تر، سریع تر، دقیق تر و کم هزینه تر در راستای سنتز cdna آ ن ها مطرح بوده است. در مطالعه حاضر با استفاده از روش مبتنی بر آنزیم های نوع iis (eco31i) اگزون های تشکیل دهنده ایزوفرم ve...
Background and purpose: Tubal pregnancy is a life threatening condition that not only causes mortality but also reduces fertility by less than 50%. In many patients, the level of βhCG does not reach detection threshold, and for definite diagnosis, long-term follow-up considering βhCG titration and transvaginal ultrasonography are needed which could lead to delay in diagnosis and treatment. The ...
diabetic macular edema (dme) is an important cause of blindness in the working population and is currently challenging to treat. current interventions include focal laser or intravitreal injections. this article outlines a new treatment protocol based on the concept that peripheral ischemia is the introduction to angiogenesis, that will ultimately gather its momentum at the fovea. performing ex...
مقدمه: لیکن پلان یک بیماری اتوایمیون مزمن التهابی با اتیولوژی نامشخص می باشد. آنژیوژنزیز فرایندی است که منجر به تشکیل عروق خونی جدید از ساختمانهای عروقی از قبل موجود می شود. نقش آنژیوژنزیز، در یک سری از حالات فیزیولوژیک یا پاتولوژیک حفره دهان شامل بیماریهای التهابی مزمن، ترمیم بافتی، تومور و متاستاز بسیار با اهمیت می باشد. هدف: هدف از مطالعه حاضر بررسی فعالیت آنژیوژنتیک در ضایعات رتیکولار، ارو...
Background: The functional longevity of ovarian transplant at present is one of the most challenging questions regarding ovary transplantation. So, we used hyaluronic acid (HA) hydrogel scaffold with combination of VEGF and bFGF for restoration of cyclical ovarian function after ovarian tissue transplantation in a rat model. Materials and Methods: A total of 25 Wistar female rats weighing betwe...
objective: vascular endothelial growth factor (vegf) and vegf receptors (vegfrs) play important roles in angiogenesis of different developmental mechanisms such as wound healing, embryogenesis and diseases, including different types of cancer. vegfr2 is associated with cell proliferation, migration, and vascular permeability of endothelial cells. blocking vegf and its receptors is suggested as ...
AIM: To evaluate the clinical efficacy and systemic safety profile of conbercept in practice on vascular endothelial growth factor (VEGF)-A, VEGF-B, placental (PLGF) levels after intravitreal injections for neovascular age-related macular degeneration (AMD). METHODS: Thirty-five patients (35 eyes) with AMD received treatment pro re nata protocol. Best-corrected visual acuity (BCVA) central reti...
