Activated Protein C renders anti-apoptotic properties in neurons and endothelial cells. The aim of the present study was to evaluate the in vivo cytoprotective role of Protein C zymogen (PC) administration in septic rat brain. Male Wistar rats (n=60) were subjected to sepsis via Cecal Ligation and Puncture (CLP). Animals were randomly divided either to(More)
BACKGROUND AND PURPOSE Renal dysfunction attributable to sepsis was long considered a result of hemodynamic instability and subsequent local ischemia. Recent data show that apoptosis may be implicated also. The purpose of this study was to evaluate the role of apoptosis and the expression of the bax, bcl-2, caspase-8, and cytochrome c proteins in the renal(More)
BACKGROUND Human adult cardiomyocytes (CM) have been used in short-term cultures for in vitro studies of the adult myocardium. However, little information is available regarding human adult CMs cultured for long term (>2 weeks). METHODS Human adult CMs were isolated from atrial specimens of 43 patients undergoing cardiopulmonary bypass surgery. Cell(More)
The 14-3-3 family members play a crucial role in the determination of cell fate, exerting their antiapoptotic activity through directly interfering with the critical function of the mitochondrial core proapoptotic machinery. Dimerization of 14-3-3 is vital for the interaction with many of its client proteins and is regulated by phosphorylation. In a(More)
BACKGROUND Many studies have suggested that the immune response may play a crucial role in the progression of hepatocellular carcinoma (HCC). Therefore, our aim was to establish a (i) functional culture of primary human tumor hepatocytes and non-tumor from patients with hepatocellular carcinoma (HCC) and (ii) a co-culture system of HCC and non-HCC(More)
AIM The present study aims to compare the host immune responses induced by benign (meningiomas) and malignant (gliomas) brain tumors. METHODS Peripheral blood samples from 8 meningioma and 7 glioma patients collected pre- and post operatively were assessed for cell-mediated immunity, humoral immunity and IL-6, IL-8 and TNF-a expression. Apoptosis and(More)
In order to further improve the toxicity profile and the anticancer effect of chlorambucil (CBL), we have synthesized a new estrone D-lactam steroidal ester of CBL (ESBL). The aim of this study was to investigate the in vitro activity of ESBL against primary breast carcinoma (BC) cells of operable tumors in comparison with CBL. Cells derived from fresh(More)
