Summary: The supplementation of HMB reduced the fat percentage in Bama Xiang mini-pigs and increased colonic acetic acid concentration and relative Bacteroidetes abundance. There was a positive correlation between Bacteroidetes abundance and acetic acid production, and a negative correlation between fat percentage and Bacteroidetes abundance or acetic acid production. HMB supplementation also upregulated the phosphorylation of AMPK alpha and downregulated the phosphorylation of mTOR.

Summary: This study investigated the effects of dietary copper supplementation on the performance, serum lipid profile, and relative mRNA abundance of genes involved in lipid metabolism in male Lezhi black goat kids. The results showed that dietary copper supplementation did not significantly affect growth performance and blood lipid levels, but it did modify lipid metabolism by increasing muscular fat and decreasing serum low density lipoprotein cholesterol. These modifications may be associated with the reduction of relative mRNA abundance of genes for oxidation of long-chain fatty acid in muscle and liver of goat kids.

Summary: This study revealed that dietary threonine deficiency affects lipid metabolism in Pekin ducks, with different effects observed in lean and fatty types. The deficiency altered the expression of genes involved in lipid metabolism in the liver, sebum, and abdominal fat of lean type ducks, but not in fatty type ducks. The findings highlight the genotype-dependent regulation of lipid metabolism by threonine deficiency in Pekin ducks.

Summary: This study investigated the effects of dietary L-theanine supplementation on finishing pigs' antioxidant capacity and lipid metabolism. The results showed that L-theanine supplementation increased the activity of antioxidant enzymes and reduced lipid levels in finishing pigs. Additionally, L-theanine activated a signaling pathway related to lipid metabolism and decreased the expression of genes related to adipogenesis. These findings suggest that L-theanine supplementation enhances antioxidant capacity and improves lipid metabolism in finishing pigs.

Summary: The research investigated the effects of different SFA:MUFA ratios on the growth performance, tissue fatty acid composition, and gene expression involved in lipid metabolism of juvenile California Yellowtail. It was found that the fish fed the control diet outperformed the experimental feeds with increasing SFA:MUFA ratio in terms of weight gain and liver index. The fatty acid composition in tissues reflected the dietary composition, with a slight sparing effect of LC-PUFA observed.

Summary: This study investigated the effects of dietary phospholipids on growth performance, fatty acid composition, and lipid metabolism in juvenile hybrid grouper. The results showed that dietary phospholipids had no significant influence on the growth performance of the grouper. However, it increased the lipid content in the fish body, liver, and muscle, and promoted hepatic triglyceride accumulation. The study also found that high dietary phospholipid inclusion decreased the expression of fatty acids oxidation related genes.

Summary: This study investigated the impacts of different crude protein (CP) levels on the antioxidant capacity of pigs at different body weight (BW) stages. The results showed that in the 5-10 kg BW range, a CP level of 20% increased antioxidant enzyme activity and glutathione (GSH) concentration. In the 10-20 kg BW range, a CP level of 16% presented the strongest antioxidant capacity. In the 20-30 kg BW range, a CP level of 14% increased antioxidant enzyme activity. Therefore, the appropriate CP levels for Huanjiang mini-pigs at the 5-10 kg, 10-20 kg, and 20-30 kg BW stages were determined to be 20%, 16%, and 14%, respectively.

Additionally, a series of capital charge error measures are proposed to evaluate the model from a regulatory perspective. Results demonstrate that the new model outperforms industry benchmarks across all evaluation measures, predictive performance is enhanced with the inclusion of macroeconomic variables, and the capital charge errors play a crucial role in evaluating the model from a regulatory standpoint.

Summary: This study constructs a fixed effect model to examine the impact of turnover of local government officials on local air quality in China. It finds that the turnover leads to a decline in local air quality due to a responsibility gap period. The study also reveals that the heterogeneity of officials and the implementation of political initiatives affect the length of the responsibility gap period, with shorter gaps resulting in lower air pollution. The findings suggest the need for further reform of the turnover system to improve local air quality during the transition of key local officials.

Summary: The study finds that exporting firms tend to have better environmental performance, but increasing export intensity does not necessarily lead to better environmental outcomes. It is shown that firms with higher export intensity have lower pollution emissions due to smaller output scale and lower energy intensity. Additionally, a slight increase in export intensity can improve firms' environmental performance by improving energy efficiency. The study provides important insights into the relationship between export intensity and environmental performance.

Summary: This article explores the role of Economic Policy Uncertainty (EPU) and Cryptocurrency Uncertainty (UCRY) indices in forecasting Bitcoin volatility. The findings suggest that the global EPU index has a significantly negative effect on long-term Bitcoin volatility, while the UCRY indices have a significantly positive effect. Furthermore, the best-performing model for forecasting incorporates the UCRY price index, outperforming models with global and national EPUs. The scarcity of application highlights the promising potential of UCRY indices in guiding Bitcoin trading behaviors.

Summary: Solid tumors have unique structures and microenvironments that are significantly different from normal tissues. This study focused on regulating the adverse factors in the tumor microenvironment (TME) to improve tumor response to various treatments. A silk fibroin-cRGDfk-Ce6 conjugate-based MnO2 nanocomposite (SRCM) was developed, which effectively alleviated hypoxia in TME, enhanced photodynamic therapy efficacy, and induced immunogenic cell death (ICD) and antigen-presenting cell (APC) activation.

Summary: This study constructs a synergistic reduction effect model of transportation tailpipe environmental negative externalities emissions based on the Kaya constant equation and the LMDI decomposition model, using inter-provincial panel data of China from 2005 to 2019. The study analyzes the synergistic impact and indirect drivers between air pollution and carbon emissions. The results show that the main drivers of the synergistic impact are energy efficiency and industrial structure. Significant synergistic emission reduction effects exist in eastern China, western China, medium-sized transportation markets, and less developed tourism regions. Furthermore, increasing environmental regulation can improve the synergistic reduction impact of air pollutants and carbon emissions from the transportation sector. This paper provides theoretical support for winning the battle of pollution prevention and control and achieving the dual carbon goal in the new era.

Summary: This paper uses China's 2017 multi-regional Input-Output table to systematically simulate the impact of the new development pattern on carbon emissions from the comprehensive perspective of production and consumption. The study finds that when the foreign circulation disappears, the total economic output will be hit hard, and carbon emissions will be greatly reduced; when the foreign circulation orientation weakens and the intensity of the domestic circulation is increased, the total economic output will increase to varying degrees, but the total carbon emissions will also increase by a certain extent. The government should promote green production and green consumption to achieve a balance between economic growth and carbon emission reduction.

Summary: This study uses data from ETS pilot firms and China's Administrative Registration Database to examine carbon leakage in conglomerates. The results show that ETS leads to carbon transfer from pilot firms to their production-connected firms, resulting in improved carbon emissions and emission intensity in these firms. Further analysis reveals that carbon leakage occurs through various channels such as output, investment, labor, and energy consumption. The study also finds that carbon leakage tends to be transferred to regions with low environmental regulations and labor costs. Overall, the study highlights the need for accurate assessment of the impact of ETS on carbon reduction.
