Article Synopsis
- The CNO cycle is a key nuclear energy process in stars, particularly significant in hydrostatic hydrogen burning at temperatures between 20 to 80 MK.
- This study reports the first direct measurements of the resonance strength of the ^{17}O(p,γ)^{18}F reaction, revealing a strength about twice as high as previously documented.
- The findings enhance our comprehension of oxygen isotopic ratios observed in red giant stars and in O-rich presolar grains, confirming consistency with earlier results from different reaction channels.
Article Synopsis
- This study analyzed the outcomes of patients who underwent mitral valve replacement (MVR) using a third-generation Mosaic porcine bioprosthesis across 11 cardiac centers from 1998 to 2011, involving 805 patients with an average age of 73.5 years.
- The median follow-up duration was 44 months, revealing early mortality rates of 3.8% for isolated elective surgeries and 7.8% overall, with a 10-year survival rate of 57.4% and various other complication rates such as thromboembolic and hemorrhagic events.
- The findings suggest that the Mosaic porcine bioprosthesis provides satisfactory early and long-term outcomes for patients undergoing MVR, with promising
We describe the case of a patient evaluated for the incidental finding of a suspected paracardiac mass. A computed tomography examination demonstrated two giant coronary aneurysms, containing endoluminal thrombi, involving both coronary arteries. Coronary angiography confirmed the diagnosis.

The patient had chronic thromboembolic pulmonary hypertension and an ascending aortic aneurysm with moderate aortic regurgitation. The procedures were concurrently completed during short periods of systemic circulatory arrest, with antegrade cerebral perfusion maintained through the brachiocephalic artery at a flow rate of 10 mL/min/kg.

The goal of this study was to evaluate the early and midterm results of total arterial CABG with the descending branch of the lateral femoral circumflex artery (DLFCA).
Methods: Between February 1997 and December 2001, 147 patients underwent arterial CABG using the DLFCA at our department.
