Some species of the Lathyrus genus are among the most promising crops for marginal lands, with high resilience to drought, flood, and fungal diseases, combined with high yields and seed nutritional value. However, lack of knowledge on the mechanisms underlying its outstanding performance and methodologies to identify elite genotypes has hampered its proper use in breeding. Chlorophyl a fast fluorescence transient （JIP test）, was used to evaluate water deficit （WD） resistance in Lathyrus genus. Our results reveal unaltered photochemical values for al studied genotypes showing resistance to mild WD. Under severe WD, two Lathyrus sativus genotypes showed remarkable resilience maintaining the photochemical efficiency, contrary to other genotypes studied. Performance index （PIABS） is the best parameter to screen genotypes with improved performance and grain production under WD. Moreover, we found that JIP indices are good indicators of genotypic grain production under WD. Quantum yield of electron transport （wEo） and efficiency with which＆trapped excitons can move electrons further than QA （c0） revealed as important traits related to improved photosyn-thetic performance and should be exploited in future Lathyrus germplasm improvements. The JIP test herein described showed to be an expeditious tool to screen and to identify elite genotypes with improved drought resistance.

Latin American Dialysis and Transplant Registry:Experience and contributions to end-stage renal disease epidemiology

引用

World Journal of Nephrology 2016年第5期5卷 389-397页

作者： Ana maria Cusumano Guillermo Javier Rosa-Diez maria carlota Gonzalez-Bedat CEMIC University Institute School of Medicine Buenos AiresPC C1430EFAArgentina Nephrology Service Italian HospitalBuenos Aires CityPC C1199ABCArgentina Latin American Society of Nephrology and Hypertension Montevideo CityPC 11600Uruguay

In 2015, 634387 million people(9% of the world's population) resided in Latin America(LA), with half of those populating Brazil and Mexico. The LA Dialysis and Transplant Registry was initiated in 1991, with the aim of collecting data on renal replacement therapy(RRT) from the 20 LA-affiliated countries. Since then, the Registry has revealed a trend of increasing prevalence and incidence of end-stage kidney disease on RRT, which is ongoing and is correlated with gross national income, life expectancy at birth, and percentage of population that is older than 65 years. In addition, the rate of kidney transplantation has increased yearly, with > 70% being performed from deceased donors. According to the numbers reported for 2013, the rates of prevalence, incidence and transplantation were(in patients per million population) 669, 149 and 19.4, respectively. Hemodialysis was the treatment of choice(90%), and 43% of the patients undergoing this treatment was located in Brazil; in contrast, peritoneal dialysis prevailed in Costa Rica, El Salvador and Guatemala. To date, the Registry remains the only source of RRT data available to healthcare authorities in many LA countries. It not only serves to promote knowledge regarding epidemiology of end-stage renal disease and the related RRT but also for training of nephrologists and renal researchers, to improve understanding and clinical application of dialysis and transplantation services. In LA, accessibility to RRT is still limited and it remains necessary to develop effective programs that will reduce risk factors, promote early diagnosis and treatment of chronic kidney disease, and strengthen transplantation programs.
