Summary: This study performed amplicon sequencing on epiphytic microbiota of four varieties of citrus fruit, and identified a series of microbes with the ability to control pathogens. Functional analysis suggested that genes related to chitinase carried by these microbes might be responsible for their disease-suppressive phenotype. In vivo test results showed that these microbes were able to reduce pathogen development for a longer time compared to separate inoculation, indicating their potential for disease control.

Summary: In this study, core/shell ZnO/TiO2 nanocomposite samples were prepared using the sol-gel method at different time spans. The sample prepared in the 15-minute time span (ZnTi15) exhibited the highest photocatalytic activity and charge carrier density, making it the optimal sample. The formation of a heterojunction at the ZnO/TiO2 interface could be attributed to the increased photocurrent density observed for the ZnTi15 sample.

Summary: By constructing a type-II heterostructure of N-doped ZnO nanowires with an ultra-thin ZnS layer, a core-shell structure is formed which can accelerate the charge transfer process and significantly enhance the resistance to photo-corrosion of N-doped ZnO NWs. The optimal ZnS/N:ZnO core-shell nanowires exhibited a photocurrent density of 0.85 mA cm(-2) at 1.23 Vs RHE, which was 3-fold higher than ZnO nanowires. The reported approach provides possibilities for the construction of efficient and highly stable PEC water-splitting devices.

Summary: A versatile hydrogen gas sensor was fabricated using Pd@ZnO core-shell nanoparticles synthesized through a hydrothermal route. The optimal sensor, Pd@ZnO-2, demonstrated superior performance compared to Pd@ZnO-1 and pure ZnO, with higher response, faster response and recovery times to 100 ppm hydrogen at 350 degrees C. The high selectivity of Pd@ZnO-2 sensor to hydrogen can be attributed to the higher metallic Pd content remaining in the sample after calcination in argon.

Summary: This study thoroughly explored the changes in intestinal microbial succession and their correlation with the production of short chain fatty acids and bioamine in piglets. The diversity of colonic microbiome community was higher than the ileum, but the composition change in the ileal microbiota was more dramatic over time. The dominant bacteria in piglets' ileum were Lactobacillus, while Prevotella and Ruminococcaceae were dominant in the colon before weaning. The gut bacterial community of piglets showed significant differences between different phases and had correlations with SCFAs and bioamines.

Summary: This study investigated the effects of gentamicin treatment on the gut microbiota composition and metabolite profile using susceptible piglet models. It was found that gentamicin significantly alleviated diarrhea and intestinal injury, increased the species richness but decreased community evenness of the gut microbiota. Gentamicin treatment also led to the formation of a novel metabolite composition profile. The KEGG database annotation revealed that arachidonic acid metabolism was downregulated while vancomycin resistance pathway was upregulated after gentamicin treatment. Furthermore, the study identified seven possible targets of gentamicin closely related to these two functional pathways through a comprehensive analysis.

Summary: This case report describes a chronically elevated exposure to copper in a German Holstein dairy herd, caused by excessive supplementation of mineral feedstuff. The study confirmed the issue of copper oversupply through various diagnostic methods including blood and urine sample analysis, total mixed ration testing, and liver biopsies. The findings suggest that fecal analysis and total mixed ration testing are reliable for assessing copper supply, while liver biopsy is deemed necessary for a dependable diagnosis of potential copper oversupply.

Summary: The study found that domestic pigs exhibited manipulation and consumption behavior towards various materials, with longer manipulation time observed for biochar and peat. Analysis showed that pigs did consume these materials, although it is yet to be determined whether the presence of undesirable substances poses a health risk. Future studies will focus on quantifying the contribution of undesirable substances from bedding, enrichment materials, and disinfectant powders to the pigs' daily feed intake.

Summary: This study quantifies the transfer of quinolizidine alkaloids (QAs) from blue sweet lupin (BSL) into cow's milk for the first time using experimental and modeling methods. The results show that QAs can transfer into milk even with a low intake of BSL, and the transfer rates vary among different QAs. A toxicokinetic model is derived to predict the transfer of QAs from feed to food. The findings suggest a potential health concern associated with the presence of QAs in milk.

Summary: Polychlorinated dibenzo-para-dioxins (PCDDs) and dibenzofurans (PCDFs), collectively known as 'dioxins', as well as polychlorinated biphenyls (PCBs) are persistent environmental contaminants that can enter the food chain and have chronic toxic effects in humans. Milk and dairy products are an important pathway for human exposure to these contaminants. Transfer of dioxins and PCBs from feed to milk has been studied, but there is still variability in the data. Factors such as experimental conditions, cow performance parameters, and metabolic state can influence the transfer. Further research is needed, especially considering the increase in milk yield in recent years.

Summary: The German Total Diet Study found that organically produced foods tend to have higher copper levels compared to conventionally produced foods. The study also revealed that grains and grain-based products are the main contributors to copper intake for all age groups. Children had copper exposure above the acceptable daily intake (ADI) set by the European Food Safety Authority (EFSA), but this is not a concern due to higher requirements related to growth. Adults who frequently consume mammalian liver or take copper-containing dietary supplements exceed the ADI.

Summary: This study observed the behavior of five dairy cows over four days when they first accessed a pasture with two sycamore maples. The results showed that the cows ingested sycamore seedlings while grazing. Metabolites of HGA and MCPrG were detected in individual milk samples on the first day of grazing, but HGA values in milk were below the limit of quantification. Higher concentrations of conjugated HGA and MCPrG metabolites were found in urine samples compared to milk. The study suggests that dairy cows may have a low susceptibility to sycamore maple toxins, but further research is needed to determine if this is due to foregut fermenting species in general.
