GM （genetically modified） corn with the CrylAb, mCry3A and Vip3Aa20 protein of Bt （Bacillus thuringiensis） and its respective isoline as control with and without chemical control for corn earworm were used in this research. Fusarium corncob damage was lower on GM corn with （12.5%） and without （25.7%） insecticide treatment as compared with the isoline that had 48.3% and 83.1% of damaged corncobs with and without chemical control, respectively. Corn smut cob damage was also lower on GM corn with （3.2%） and without （6.3%） insect control compared with 15.5% and 49.7% damage with and without insecticide treatment, respectively. Fusarium sp. corncob rot was also lower on GM corn with 5.7% and 9.5% whereas a 24.6% and 63% rot was observed on the isoline with and without insecticide control, respectively. Ustilago maydis severity was also lower on Bt corn finding 0.07% and 0.25% damage on treatments with and without insect control as compared with the isoline that showed an 11.6% and a 41.4% smut rot with and without insecticide treatment, respectively. The authors conclude that GM corn resistant to Helicoverpa zea prevents damage by the pest, eliminating the entrance pathway for Fusarium sp. and Ustilago maydis.

Benthic foraminifera are excellent environmental indicators;CaCO3 test records the isotopic concentration of their surroundings and can be used to analyze environmental changes that occur during a certain time period. Stable isotopes, particularly those of oxygen (δ18O), are useful for interpreting ancient environments, given that they are used as “proxy” environmental variables (temperature and salinity). In this study, we provide ranges of isotopic variation in benthic foraminifera communities from the Colorado River delta. Four sampling campaigns were conducted in one year (2009-2010) in the adjacent subtidal zone of Baja California. Four transects with a total of sixteen sample station were drawn perpendicular to the coastline. Here, we recorded the following in situ: sand-type, salinity, and temperature. In the laboratory, 300 individuals per sample were separated, and sub-samples were taken for isotopic analysis. Data was processed using the software’s R 2.12.2, PAST 1.81 and Arc Map 9.3. Forty species were identified in the dead assemblages (Thanatocoenosis), whereas thirteen species were found in the living assemblages (Biocoenosis). The most abundant species in both communities belong to the genera Ammonia and Cribroelphidium. In the living assemblages, isotopic variation −2.15% to 5.94% within a temperature interval of 11°C, indicated antiestuarine conditions. In the dead assemblages, isotopic composition −3.04 to −0.74 served as a sign of estuarine conditions prior to damming.

Gut microbiota plays an important role in cirrhosis. The liver is constantly challenged with commensal bacteria and their products arriving through the portal vein in the so-called gut-liver axis. Bacterial translocation from the intestinal lumen through the intestinal wall and to mesenteric lymph nodes is facilitated by intestinal bacterial overgrowth, impairment in the permeability of the intestinal mucosal barrier, and deficiencies in local host immune defences. Deranged clearance of endogenous bacteria from portal and systemic circulation turns the gut into the major source of bacterialrelated complications. Liver function may therefore be affected by alterations in the composition of the intestinal microbiota and a role for commensal flora has been evidenced in the pathogenesis of several complications arising in end-stage liver disease such as hepatic encephalopathy, splanchnic arterial vasodilatation and spontaneous bacterial peritonitis. The use of antibioticsis the main therapeutic pipeline in the management of these bacteria-related ***,other strategies aimed at preserving intestinal homeostasis through the use of pre-,pro-or symbiotic formulations are being studied in the last *** this review,the role of intestinal microbiota in the development of the most frequent complications arising in cirrhosis and the different clinical and experimental studies conducted to prevent or improve these complications by modifying the gut microbiota composition are summarized.

在新冠肺炎疫情的背景下,各国央行的行动,配合财政支持和灵活监管,使全球经济迎来了强劲、快速的复苏。这绝非易事,央行必须在很大的不确定性下作出决策,艰难权衡。接下来将是一条危险的道路,很大程度上取决于央行如何应对。除了宏观经济困难,数字化正在改变金融和货币体系的结构,需要予以关注。因此,笔者想着重强调央行在未来几年将面临的主要挑战。

研究了钛盐无铬鞣剂对于污水及固体废弃物的影响。将采用不同鞣剂鞣制后的皮革废弃物与食品垃圾一起在实验室堆肥。结果表明:钛盐鞣制后的皮革废弃物符合降解质量标准。此外,与铬鞣剂相比,钛盐鞣制后皮革废弃物中的有机物和盐含量较低。通过堆肥降解研究,发现钛盐鞣制后皮革中碳含量降低了约10%,且C/n比降低,堆肥降解45d皮革面积可降解41%。噁唑烷鞣制后的皮革,堆肥后仅部分降解,而铬鞣革和植鞣革均未发生降解。
