abstract background autologus platelet gel is easy to prepare and is relatively low cost. the aim of this study was to prepare and evaluate in vitro efficacy of autologus platelet gel. materials and methods in this experimental study, platelet concentrate and platelet poor plasma were prepared with aphaeresis method. thrombin was prepared by mixing the plasma with calcium. thrombin activity lev...
breast cancer is the most common cause of cancer-related death in female, after lung cancer. angiogenesis is essential for tumor growth and metastasis; therefore, antiangiogenesis strategies for treatment of cancer are currently an issue of interest. the role of vascular endothelial growth factor that assumed to be most potent angiogenesis factor is ambiguous in breast cancer. this study descri...
BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal rando...
Introduction: Researchers have always been interested in the close and mutual relationship between the pulp and periodontal tissues. Although the effects of pulpal disease on periodontium have been well known, the clear relationship between periodontitis and pulp has not been documented . It seems that bacteria and inflammatory products of periodontitis can affect pulp through accessory canals,...
Objective(s):Althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. Adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm DNA fragmentation and infertility. The post-thaw survival of sperm...
از آنجا که کیفیت جنین حاصل از بلوغ آزمایشگاهی تخمک (in vitro maturation) در مقایسه با جنین حاصل از تخمک بالغ شده در شرایط طبیعی بدن (in vivo maturation)، پایین تر از حد انتظار است، بهبود مطالعات مربوط به عوامل تنظیمی پتانسیل تکوین تخمک ضروری است. از طرف دیگر پیشگویی و بهبود شایستگی تکوین (developmental competency) تخمک دو مسئله اساسی در تکنیک های تولیدمثلی (assisted reproductive techniques) هست...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
background : insulin-like growth factor-1 can act in both an autocrine and paracrine manner to promote normal growth and malignant cellular proliferation. the importance of this factor as a major regulatory peptide has been established for cells, in vitro and in vivo. however, the role of serum insulin-like growth factor-1 levels in the etiology of benign prostatic hyperplasia and prostate canc...
