ischemia-reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. ischemia-reperfusion brain injury initiates an inflammatory response involving the expression of adhesion molecules and cytokines. twenty–four male wistar rats (250-300 g body wt) were used in this study. the animals were divided into four groups of 6 rat...

Apoptosis, programmed cell death, has a central role in developmental biology and maintaining the equilibrium of renewing tissues. A founding member Bcl-2 family regulatory proteins for apoptosis is Bcl-2, which encoded by BCL2 gene. Caspase-3 shares typical features with all caspases, including acting as crucial mediator apoptosis.

Alternatif tıpta kemoterapi benzeri tedavi yöntemlerine ek olarak sıklıkla bitkisel kökenli doğal ilaçlar kullanılmaktadır. Panax ginseng bunlardan biridir ve sinir sistemi kaynaklı hastalıklarda tercih edilmektedir. Çalışmamızda amaç, sisplatinden önce kullanılan ginsengin YKG1 glioblastoma hücrelerinde hücre ölümü canlılığı bakımından değerlendirilmesidir. Ticari satın alınan hücreleri, % 5 C...

background and objectives: giant cell tumor of bone (gct) is often regarded as a benign tumor, but its clinical course is unpredictable, has a high rate of recurrence, and even can metastases and transform to a malignant tumor. histological features of the tumor often could not predict its future biologic behavior, so it is just called ''giant cell tumor'' without indicating malignancy or benig...

background & objective: the current approaches to reduce the risk of colorectal carcinoma are through the detection and removal of the precursor lesion” adenomatous polyps”. the study was conducted to evaluate the immunohistochemical expression of p53 and bcl2 in colorectal adenomas and carcinomas. patients and methods: a total of 86 cases, 33 colorectal adenomas, 33 colorectal adenocarcin...

Back ground: Although the cell differentiation is an inseparable part of development in multicellular organisms, the regulating molecular pathway of it still is not fully defined. In the other hand, apoptosis is a fundamental physiological process which plays an essential role in a variety of biological events during development. Moreover, recent studies have found that apoptosis shows several ...
