Cucumber mosaic virus (CMV) has the broadest host range, infecting more than 1300 species in more than 500 genera from over 100 botanical families. In ornamental plants, CMV can cause mosaic and distortion of leaves, stunting, color break, and malformation of flowers. CMV coat protein (CP) sequences obtained from seven ornamental plants and other homologous sequences available in GenBank were compared, and phylogenetic relationships were established. Total RNA from virus-infected ornamental species were extracted, submitted to RT-PCR with specific primers, and amplicons obtained were sequenced. A nucleotide substitution model and phylogenetic analyses were carried out using the PAUP program. The seven sequences of CMV CP obtained showed similar identity percentages and close relationships with subgroup I isolates from other countries and hosts. CMV isolates from different regions of S?o Paulo state, Brazil (Salvia splendens, Catharanthus roseus, Nematanthus nervosus (=Hypocyrta nervosa), Impatiens walleriana, Eucharis grandiflora and Commelina sp.) formed a monophyletic group, indicating a possible common origin. It was found that when lily sequences of CMV only from different geographic regions were compared, Brazilian isolates shared the same common ancestor with those from Poland and Taiwan. Furthermore, this monophyletic group presented a quite basal position.

Free amino acid and pigment composition in fruits at two ripening stages from a selected tomato germplasm was stu-died. The aims were contributing to knowledge on variability of ripening metabolism and identifying more consis-tently the genetic background of the plant material under analysis. Significant differences (p < 0.05) were found among ripening stages and among genotypes within ripening stage for all amino acids and pigments except by asparagine, alanine and chlorophyll b contents. The highest relative amino acid content corresponded to glutamate, glutamine, and GABA though some genotypes had relatively high asparagine content. Glutamate, glutamine and GABA performed oppositely: the former increased along ripening while the latter two decreased in their relative content. A Principal Components (PC) analysis was applied, determining that metabolites having the greatest contribution to general variability were threonine, serine, glutamate, glutamine, glycine, isoleucine, leucine, tyrosine, phenylalanine, lycopene and beta- carotene, which showed the highest association with PC1. Alanine and chlorophylls a and b were highly associated to PC2. These two first PC explained the 62% of the total variation, and genotypes were distributed according to the ripening stage in their coordinates. Accordingly, a Hierarchical Clustering resulted in a dendrogram having a relatively high cophenetic correlation (0.70), in which two well defined groups were obtained according to ripening stage. These results verified the existence of variability in the metabolism of ripening fruit for amino acids and pigments, and allowed to identify unequivocally a set of selected tomato germplasm according to the fruit metabolic profiles in these two ripening stages.

Cardiorenal syndrome is a severe and potentially lethal disease in which heart and kidney failures coexist. The classic treatment with loop diuretics is ineffective due to the resistance of the kidney to those drugs, which requires the use of other therapies, such as extracorporeal ultrafiltration and peritoneal dialysis. This last technique is useful both in the acute treatment of acute heart decompensation and the chronic management of heart failure, because it improves heart function by reducing the volume overload, which in turn contributes to improving the kidney function with a limited number of side effects, which makes it the technique of choice for the treatment of diuretic-resistant heart failure. In this review, we present a description of the different kinds of cardiorenal syndrome, as well as the different treatments that are used, with special attention to the different modalities of peritoneal dialysis.

40年来,硅谷银行(Silicon ValleyBank)将自己融入了风险投资圈,常常带着一种备受喜爱的家乡银行的舒适触感。红杉资本(Sequoia Capital)合伙人迈克尔·莫里茨(Michael Moritz)将这家银行比作“受人喜爱的本地市场”,柜台后面的人知道每一位顾客的名字,微笑着把自己的肉割下来卖给他们。他在3月12日《金融时报》(Financial Times)的一篇专栏文章中写道,你可以指望硅谷银行及其员工“打理社区花园、提供食品银行或者向老年人提供陪伴服务”。他说,直到事件发生之前,红杉资本一直建议新的初创公司在硅谷银行开户。
