Methods. Immunohistochemistry was used to examine the expression of p27 in 130 primary NPC tissues. The relationship between the levels of p27 expression and clinicopathologic characteristics was analyzed. Survival curves were plotted using the Kaplan-Meier method and compared using the log-rank test. The significance of various survival variables was analyzed using multivariate Cox

proportional hazards model. Results. p27 was expressed in both nuclear and cytoplasmic compartments. Nuclear expression of p27 was inversely correlated with T classification and clinical stage. Patients with nuclear p27 expression had better overall survival rates than those without nuclear RSL-3 expression of p27. Further, we observed that nuclear expression of p27 was positively

associated with survival time of NPC patients not only in N0-1 and M0 classifications but also in radiotherapy and chemotherapy treatment groups. Finally, we found that nuclear expression of p27 was not an independent prognostic factor for Src inhibitor patients with NPC. Conclusions. Our findings hint that nuclear expression of p27 is a potentially favorable factor in the progression and prognosis of NPC.”
“Aims: There are several epidemiological studies suggesting that moderate daily consumption of red wine may reduce cardiovascular risk. Additionally, results from a great number of in vitro studies indicate that constituents found in red wine are responsible for quite a few beneficial effects on endothelial cells. However, comparison of postprandial studies and clinical trials concerning red wine consumption leads to controversial results about its effect on endothelial function and especially flow-mediated

dilatation (FMD).

Endothelial function is an early indicator of atherosclerosis and vessel damage and at the same time, it is an independent prognostic factor for cardiovascular risk. Therefore, it is very important BIIB057 price to investigate the known acute postprandial effects of red wine consumption, which is highly advised by dieticians and doctors, especially in high-risk populations, Such as patients with coronary artery disease (CAD).

Data synthesis: This is a review of studies investigating acute and short-term effects of red wine on endothelial function, as well. as relevant in vitro studies.

Conclusion: Analysis of all data about the acute effects of red wine constituents on endothelial function, is inconclusive and it is obvious that new studies are necessary in order to elucidate this matter. Undoubtedly, one should be very careful in suggesting red wine consumption in high-risk populations, as its acute postprandial effect is not yet clear. (C) 2009 Elsevier B.V. All rights reserved.”
