All patients underwent angiographic control 6 months postoperatively. The end points were major adverse cerebrocardiovascular events and proportion of grafts patent or functional at follow-up angiography.
Results: There were no significant differences between the 2 groups in terms of hospital events. At follow-up there was no significant difference in major adverse cerebrocardiovascular events between the 2 groups. At the 6-month angiographic follow-up, 91% of the anastomoses in the right gastroepiploic artery group and 95% of the anastomoses in the saphenous vein graft group were controlled patent (P = .92). In nonoccluded right coronary arteries,
the proportion of patent grafts was significantly lower and the proportion
Conclusion: There were no significant patency or major adverse cerebrocardiovascular events rate differences between the 2 Groups; however, the number of functional grafts was significantly higher in the saphenous vein graft group. Careful selection of the coronary target is mandatory to obtain good results in gastroepiploic artery grafting.”
“Apoptosis is a natural cell elimination process involved in a number of physiological and pathological events. This process can be regulated by members of the Bcl-2 family. Bax, a pro-apoptotic member of this family, accelerates cell death, while the pro-survival member, Bcl-X-L, can antagonize the pro-apoptotic function of Bax to promote cell survival. In the present study, we have evaluated the effect of Bcl-X-L on Bax-induced alterations in mitochondrial. respiration and calcium this website release. We found that in primary cultured astrocytes, recombinant Bcl-X-L is able to antagonize Bax-induced decrease in mitochondrial respiration and increase in mitochondrial. calcium release. In addition,
we found that Bcl-X-L can lower the calcium store in the endoplasmic reticulum, thus limiting potential calcium flux induced by apoptosis. This regulation of calcium flux by Bcl-X-L may represent an important mechanism by which this protein promotes cell survival. (c) 2008 Elsevier Ireland Ltd. All rights reserved.”
“Objective: We assessed the efficacy of our newly modified technique, namely, less invasive quick replacement with rapid rewarming, for octogenarians undergoing emergency surgery for type A acute aortic dissection.
Methods: Forty-two patients with acute aortic dissection, whose average age was 8 1.7 +/- 2.3 years, were divided into two groups: group I consisted of 25 patients undergoing surgery with deep hypothermic circulatory arrest and selective cerebral perfusion; group 11 consisted of 17 recent patients who underwent less invasive quick replacement.
