background and aims: p504s (amacr) is a mitochondrial enzyme expressed in renal cell carcinoma. some of immunohistochemical markers in renal cell tumors are independent prognostic factor and show relation with histologic grading. amacr expression increases with higher histological grading in different tumors; however, in rcc it is not obvious. in this study, we tried to investigate if any relat...

background autologous platelet concentrate has been used to improve the function and regeneration of injured tissues. tendinopathies are common in clinical practice, although long-term treatment is required. on the basis of lead time, we compared the effect of using platelet-rich plasma (prp) and platelet-rich fibrin (prf) in repairing rat achilles tendon. methods the effectiveness of using prp...
