1隔沟交替灌溉对我国半干旱地区马铃薯水分利用的影响显示文摘隔沟交替灌溉(Partial root-zone drying,PRD)被认为是一种节水灌溉的方法,它可以提高多种作物的水分利用率。本研究开展于我国甘肃与内蒙两个半干旱马铃薯种植区,比较常规灌溉与隔沟交替灌溉对马铃薯产量和水分利用率的影响。结果表明,由于两个试验点的气候条件与土壤条件不同,所以马铃薯产量存在显著的差异。但是在两试验点中,PRD50处理(隔沟交替灌溉,灌水量为经验灌水量的1/2)的产量与常规灌溉处理(C100,经验灌水量)的产量没有显著的差别,水分利用率却显著提高。研究显示,运用合理的灌溉方式,可以在保证产量不变的基础上节省用水量。另外,在易发生干旱的地区,选用适合的品种,同时采用覆膜技术对于增加马铃薯产量有着重要的作用。谢开云 王晓雪 张若芳 巩秀峰 张世彪 MARES Victor GAVILAN Carla POSADAS Adolfo QUIROZ Roberto 2012中国马铃薯2012,26,1:7
2Fungal endophytes in green coffee seeds显示文摘Green coffee seeds from Colombia, Guatemala, India, Kenya, Papua New Guinea, Puerto Rico and Vietnam were sampled for the presence of fungal endophytes. Stions of surface sterilized seeds were plated on yeast malt agar, and fungal growth was isolated for subsequent DNA extraction and sequencing. Several fungal genera were isolated, including Acremonium, Aspergillus, Eurotium, Fusarium, Gibberella, Penicillium, Pseudozyma and an undescribed clavicipitaceous species. The biological activities that these fungi might be playing in coffee seeds remain unknown, but in other plants some of the genera isolated have been reported to protect against plant pathogens.Femando E.

3Tacrolimus confers lower acute rejection rates and better renal allograft survival compared to cyclosporine显示文摘AIM To compare the impact of tacrolimus(FK) and cyclosporine(CYA) on acute rejection and graft survival and to assess the predominant causes of graft loss between patients receiving these two calcineurin inhibitors(CNIs).METHODS Retrospective review of 1835 patients who received a kidney transplant(KTX) between 1999-2012. Patients were grouped based on initial CNI utilized: 1195 in FK group, 640 in CYA group. Data on baseline characteristics, clinical outcomes, and causes of graft loss in both groups were analyzed. RESULTS Cumulative acute rejection rates were 14% in the FK vs 24% in the CYA group. Despite more marginal donor characteristics in the FK group, these patients had better graft survival rates compared to the CYA group. Three and five year graft survival rates were 88% and 84% respectively in the FK group compared to 79% and 70% respectively in the CYA group(P < 0.001). After multivariate analysis, which controlled for confounders, FK use was a strong predictor for lower acute rejectionrates [odds ratio(OR) 0.60, 95%CI: 0.45-0.79] and better renal allograft survival(OR 0.740, 95%CI: 0.58-0.94). Death with a functioning graft was the most common cause of graft loss in both groups. Common causes of death included cardiovascular disease, infections, and malignancies. Chronic allograft nephropathy was also found to be an important cause of graft loss, being more prevalent in the CYA group. CONCLUSION The use of FK-based maintenance immunosuppression therapy is associated with a significantly lower rate of acute rejection and better graft survival compared to CYA-based regimen. Individualizing immunosuppression through risk-stratified CNI choice may lead to improved outcomes across all spectra of KTX patients.Mahmoud Kamel Manish Kadian Titte Srinivas David Taber Maria Aurora Posadas Salas 2016World Journal of Transplantation2016,6,4:2
