We report deep level transient spectroscopy results from ZnO layers grown on silicon by molecular beam epitaxy （MBE）, the hot probe measurements reveal mixed conductivity in the as-grown ZnO layers, and the current-voltage （l-V） measurements demonstrate a good quality p-type Schottky device. A new deep acceptor level is observed in the ZnO layer having activation energy of 0.49 ± 0.03 eV and capture cross-section of 8,57 ×10^-18 cm^2. Based on the results from Raman spectroscopy, photoluminescence, and secondary ion mass spectroscopy （SIMS） of the ZnO layer, the observed acceptor trap level is tentatively attributed to a nitrogen-zinc vacancy complex in ZnO,

Surgical revascularization with coronary artery bypass grafting(CABG) has become established as the most effective interventional therapy for patients with moderately severe and severe stable ischemic heart disease(SIHD). this recommendation is based on traditional 5-year outcomes of mortality and avoidance of myocardial infarction leading to reintervention and/or cardiac death. However, these results are confounded in that they challenge the traditional CABG surgical tenets of completeness of anatomic revascularization, the impact of arterial revascularization on late survival, and the lesser impact of secondary prevention following CABG on late outcomes. Moreover, the emergence of physiologic-based revascularization with percutaneous cardiovascular intervention as an alternative strategy for revascularization in SIHD raises the question of whether there are similar physiologic effects in CABG. Finally, the ongoing ISCHEMIA trial is specifically addressing the importance of the physiology of moderate or severe ischemia in optimizing therapeutic interventions in SIHD. So it is time to address the role that physiology plays in surgical revascularization. the long-standing anatomic framework for surgical revascularization is no longer sufficient to explain the mechanisms for short-term and long-term outcomes in CABG. Novel intraoperative imaging technologies have generated important new data on the physiologic blood flow and myocardial perfusion responses to revascularization on an individual graft and global basis. Long-standing assumptions about technical issues such as competitive flow are brought into question by real-time visualization of the physiology of revascularization. Our underestimation of the impact of Guideline Directed Medical therapy, or Optimal Medical therapy, on the physiology of preoperative SIHD, and the full impact of secondary prevention on post-intervention SIHD, must be better understood. In this review, these issues are addressed through the

＜正＞ Limitations in the size and amount of bone tissue produced in vitro via tissue engineering are mainly due to the lack of nutrient and oxygen supply to the cells some distance away from the surface. Our laboratory has investigated possibilities for growing bulky bone tissue using novel hollow fibre bioreactors. the hollow fibre membranes embedded in the three dimensional scaffold are porous and semi permeable, which can serve the function of arteries and veins. Foam-type polycaprolactone （PCL） was used as a 3D scaffold and cellulose acetate hollow fibre membranes were embedded within the 3-D constructs. Rat bone marrow fibroblastic （RBMF） cells were initially seeded onto PCL scaffolds and then
