A lower richness and an increased beta-diversity characterized the fecal microbiota composition of Salmonella-positive animals after transport. In this stage, a natural Salmonella infection causes a disruption of the fecal microbiota as observed in challenge studies.Body temperature responses were recorded during phases of work (waiting-to-work in close proximity to search site, active work in a search site, and post-work recovery crated in vehicle) in human remains detection dogs during search training. State or federally certified human remains detection dogs (n = 8) completed eight iterations of searching across multiple novel search environments to detect numerous scent sources including partial and complete, buried, hidden, or fully visible human remains. Internal temperature (Tgi) of the body was measured continuously using an ingestible thermistor in the gastrointestinal tract. Mean total phase times were waiting-to-work 9.17 min (±2.27); active work 858 min (±249); and post-work recovery 2404 min (±10.59). Tgi was impacted by phase of work (p less then 0.001) with a small increase during active work, with mean peak temperature 39.4 °C (±0.34 °C) during that period. Tgi continued to increase for a mean of 637 (±604) min into the post-work recovery phase in the handler's vehicle with a mean peak Tgi of 39.66 °C (±0.41 °C). No significant increase in temperature was measured during the waiting-to-work phase, suggesting behaviors typical of anticipation of work did not appear to contribute to overall body temperature increase during the waiting-to-work recovery cycle. Continued increase of gastrointestinal body temperature several minutes after cessation of exercise indicates that risk of heat injury does not immediately stop when the dog stops exercising, although none of the dogs in this study reached clinically concerning body temperatures or displayed any behavioral signs suggestive of pending heat injury. More work is needed to better understand the impact of vehicle crating on post-work recovery temperatures in dogs.Hospitals need to prepare large amounts of domestic hot water (DHW) to develop their healthcare activity. The aim of this work was to analyse potential savings that can be achieved by installing solar thermal energy for production of domestic hot water in the hospitals of Extremadura (Spain). For this purpose, 25 hospitals between 533 and 87,118 m2 and between 15 and 529 beds were studied, three solar factor scenarios were simulated (0.70, 0.75 and 0.80) and the necessary investment and corresponding economic and environmental savings were calculated. Better economic results and energy ratios for 70% of solar contribution were obtained. These results show an average payback of 4.74 years (SD = 0.26) reaching 4.29 kWh/€ per year (SD = 0.20). Undertaking an investment of 674,423 €, 2,895,416 kWh/year of thermal energy could be generated with which to save both 145,933 € and 638 tons of CO2 per year. It was statistically demonstrated the priority of carrying out an installation with a solar factor of 70%, investing preferably in hospitals in Cáceres over those in Badajoz, especially in the public sector with more than 300 beds. These findings will provide hospital managers with useful information to make decisions on future investments.Aflatoxin B1 (AFB1) is one of the most dangerous mycotoxins in both humans and animals. Regulation of resveratrol is essential for the inhibition of AFB1-induced oxidative stress and liver injury. buy NVP-AUY922 Whether N6-methyladenosine (m6A) mRNA methylation participates in the crosstalk between resveratrol and AFB1 is unclear. The objective of this study was to investigate the effects of AFB1 and resveratrol in m6A RNA methylation and their crosstalk in the regulation of hepatic function in mice. Thirty-two C57BL/6J male mice were randomly assigned to a CON (basal diet), RES (basal diet + 500 mg/kg resveratrol), AFB1 (basal diet + 600 μg/kg aflatoxin B1), and ARE (basal diet + 500 mg/kg resveratrol and 600 μg/kg aflatoxin B1) group for 4 weeks of feeding (n = 8/group). Briefly, redox status, apoptosis, and m6A modification in the liver were assessed. Compared to the CON group, the AFB1 group showed increased activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT), prevalent vacuolization and cell edema, abnormal redox status, imbalance apoptosis, and especially, the higher expression of cleaved-caspase-3 protein. On the contrary, resveratrol ameliorated adverse hepatic function, via increasing hepatic antioxidative capacity and inhibiting the expression of cleaved-caspase-3 protein. Importantly, we noted that reactive oxygen species (ROS) content could be responsible for the alterations of m6A modification. Compared to the CON group, the AFB1 group elevated the ROS accumulation, which led to the augment in m6A modification, whereas dietary resveratrol supplementation decreased ROS, followed by the reduction of m6A levels. In conclusion, our findings indicated that resveratrol decreased AFB1-induced ROS accumulation, consequently contributing to the alterations of m6A modification, and eventually impacting on the hepatic function.Flax (Linum usitatissimum L.) is an important oil seed crop that is mostly cultivated in temperate climates. In addition to many commercial applications, flax is also used as a fibrous species or for livestock feed (animal fodder). For the last 40 years, flax has been used as a phytoremediation tool for the remediation of different heavy metals, particularly for phytoextraction when cultivated on metal contaminated soils. Among different fibrous crops (hemp, jute, ramie, and kenaf), flax represents the most economically important species and the majority of studies on metal contaminated soil for the phytoextraction of heavy metals have been conducted using flax. Therefore, a comprehensive review is needed for a better understanding of the phytoremediation potential of flax when grown in metal contaminated soil. This review describes the existing studies related to the phytoremediation potential of flax in different mediums such as soil and water. After phytoremediation, flax has the potential to be used for additional purposes such as linseed oil, fiber, and important livestock feed.
