Pre-kidney transplant cardiac screening has garnered particular attention from guideline committees as an approach to improving post-transplant success. Screening serves two major purposes: To more accurately inform transplant candidates of their risk for a cardiac event before and after the transplant, thereby informing decisions about proceeding with transplantation, and to guide pre-transplant management so that posttransplant success can be maximized. Transplant candidates on dialysis are more likely to be screened for coronary artery disease than those not being considered for transplantation. Thorough history and physical examination taking, resting electrocardiography and echocardiography, exercise stress testing, myocardial perfusion scintigraphy, dobutamine stress echocardiography, cardiac computed tomography, cardiac biomarker measurement, and cardiac magnetic resonance imaging all play contributory roles towards screening for cardiovascular disease before kidney transplantation. In this review, the importance of each of these screening procedures for both coronary artery disease and other forms of cardiac disease are discussed.

It is a fact that global health indicators in vulnerable populations are not improving, despite all resources concentrated in this area. Therefore, as a teacher and researcher in an international doctorate in Public Health, I took advantage of the contact with health professionals from Colombia, Peru and Bolivia (they were all my students) to try to better understand which factors may be affecting this paradox from the perspective of the major actors and therefore through a qualitative methodology. The main conclusion is that the health goals for the target populations (emerging and developing countries) are not the same as the goals for the planners and administrators of public health budgets. So if we want to improve health outcomes, it is time to let talk the people involved, and to let the administrators listen.

随着光伏发电和电动汽车的快速发展,电网的安全和经济运行受到了更多的关注,开展关于能量管理问题的研究有助于保证电网的稳定和高效运行。文中针对并网模式下计及电动汽车和光伏—储能的微网能量管理问题,研究了根据电动汽车电池的荷电状态进行能量管理的功率计算模型,提出了兼顾光伏出力、电动汽车充放电功率、电网电价时段划分及储能能量状态的能量管理策略。在此基础上,建立了以电动汽车充放电功率为优化变量,以减少微网运行费用为目标的能量管理模型,并采用基于遗传算法与粒子群算法的混合优化算法(GAPSO)进行求解。最后以实际微网为例进行仿真,结果验证了所述方法的有效性和可行性。

梗阻性肥厚型心肌病（HCM）间隔切除术的治疗方法几乎与HCM文献报道同时出现。现在越来越清楚的表明，间隔切除术是一种缓解流出道梗阻症状最可靠的治疗方法。间隔切除术在HCM治疗中地位的不断提高，主要是因为：（1）对梗阻的患病率及其影响认识更加清楚；（2）通过与酒精消融术的比较，使我们对该术式的认识更加清楚。下面我们介绍一下Mayo医院外科治疗HCM的经验。

Cytokines like interferons （IFNs） play a central role in regulating innate and specific immunities against the pathogens and neoplastic cells. A number of signaling pathways are induced in response to IFN in various cells. One classic mechanism employed by IFNs is the JAK-STAT signaling pathway for inducing cellular responses. Here we describe the non-STAT pathways that participate in IFN-induced responses. In particular, we will focus on the role played by transcription factor C/EBP-β in mediating these responses.

We develop a new fully quantum method for determination of widths for nuclear decay by proton emission where multiple internal reflections of wave packet describing tunneling process inside proton-nucleus radial barrier are taken into account. Exact solutions for amplitudes of wave function, penetrability T and reflection R (estimated for the first time for decay problem) are found for n -step barrier (at arbitrary n) which approximates the realistic barrier. In contrast to semiclassical approach and two-potential approach, we establish by this method essential dependence of the penetrability on the starting point Rform in the internal well where proton starts to move outside (for example, for Ta the penetrability is changed up to 200 times;accuracy is T+R-1|-15 ). We impose a new condition: in the beginning of the proton decay the proton starts to move outside from minimum of the well. Such a condition provides minimal calculated half-life and gives stable basis for predictions. However, the half-lives calculated by such an approach turn out to be a little closer to experimental data in comparison with the semiclassical half-lives. Estimated influence of the external barrier region is up to 1.5 times for changed penetrability.

Wax esters were derived from long chain fatty acids and long chain alcohols with chain length of 12 carbons or more. These compounds have many potential applications in cosmetics, pharmaceuticals and food industries. The present work focuses on the synthesis of wax esters using palm fatty acid distillate and oleyl alcohol catalyzed by Amberlyst 15. Response surface methodology （RSM） based on a five-level, three-variable central composite design （CCD） was used to evaluate the interactive effects of synthesis, of amount of Amberlyst 15 catalyst （21.6-38.4% w/w）, reaction time （18-102 min） and molar ratio （palm fatty acid distillate to oleyl alcohol, 1：1.16-1：2.84） on the percentage conversion of palm fatty acid distillate. The optimum conditions derived via RSM were： amount of catalyst 33% w/w, reaction time 95 minute and palm fatty acid to oleyl alcohol molar ratio 1：2.7. The actual experimental conversion was 81.52% under optimum condition, which compared well to the maximum predicted value of 80.50%. Analysis of the yield showed that at optimum condition, 80.54% wax esters were produced.
