Summary: The application of cold exposure has shown to enhance lipid catabolism in the human body. However, the effect of cold exposure on the lipidome varies depending on the intensity and duration of exposure. Through sequential lipidomic profiling, this study found that cold exposure gradually increased circulating free fatty acids in humans, while temporarily decreasing total triacylglycerols (TAGs) at 30 minutes. Different TAG species showed varying responses, with the initial decrease in unsaturated and polyunsaturated TAG species with <= 5 double bonds, followed by a significant increase in polyunsaturated TAG species with >= 6 double bonds after 120 minutes. A mechanistic study in mice revealed that the increase in polyunsaturated TAGs induced by cold exposure was largely prevented by blocking adipose triglyceride lipase. These findings suggest that cold exposure promotes the utilization of TAG-derived fatty acids for thermogenesis, resulting in a decrease in circulating TAG species and an increased production of polyunsaturated TAG species by the liver.

Summary: This study uncovers the effect of nitrogen deprivation on fatty acid desaturation and its regulatory mechanism. Early nitrogen deprivation reduces fatty acid desaturation without increasing lipid content. Lipidomic analysis reveals the transfer of unsaturated fatty acids from phospholipids and glycolipids to triacylglycerols. Functional characterization identifies certain transcription factors playing important roles in promoting total fatty acid accumulation and reducing fatty acid desaturation.

Summary: This study explores the role of OsTIL1 lipocalin in maintaining cell membrane integrity under cold stress. The findings show that OsTIL1 positively regulates cold stress tolerance by protecting the cell membrane from oxidative damage and enhancing the activities of peroxidase and ascorbate peroxidase. OsTIL1 overexpression induces higher levels of 18:3-mediated glycerolipids and increases the transcription and enzyme abundance of four x-3 FADs under cold stress.

Summary: This study reveals the role of BRS1 in plant redox regulation and stress responses. BRS1 interacts with cytosolic NADP+-dependent isocitrate dehydrogenase to regulate cellular redox. Additionally, a novel alternative splice form of the BRS1 gene was identified in the over-expression mutant brs1-1D, which may have a new role in plant development and stress responses.

Summary: Plant cell wall biosynthesis is a complex process that needs to be tightly regulated to accommodate environmental stresses and the needs of rapidly growing cells. Salt stress can cause severe damage to plant cell walls, leading to reduced productivity and yield. Plants respond to salt stress by modifying the synthesis and deposition of cell wall components to prevent water loss and reduce ion transport. This review discusses the roles of cell wall components in salt stress tolerance and the regulatory mechanisms involved.

Summary: Enterprises in emerging markets increasingly prioritize social responsibility alongside economic development. However, existing literature lacks research on the relationship between corporate social responsibility (CSR) and acquirer returns in cross-border mergers and acquisitions (M&As). This study examines 214 cross-border M&As in China from 2010 to 2019 and categorizes CSR into four components. The findings indicate that supplier and consumer responsibility, as well as the social contribution of enterprises, significantly promote acquirer returns in cross-border M&As, while shareholder responsibility and environmental responsibility have negative effects. This conclusion may be specific to the Chinese context of cross-border M&As.

Summary: This paper investigates the problem of overcoming controller vulnerability in nonlinear uncertain switched systems considering actuator saturation. The sufficient condition for nonfragile robust exponential stabilization is derived using the method of minimum dwell time. Switching law and nonfragile state feedback controllers are then designed to achieve robust exponential stabilization. Additionally, the design issue of controllers is transformed into a convex optimization problem with linear matrix inequalities (LMI) constraints, aiming to enlarge the estimation of domain of attraction for the closed-loop system.

Summary: High-entropy alloys/compounds with increased configurational entropy exhibit improved functional properties compared to conventional materials. In this study, the impact of increasing entropy in liquid electrolytes for rechargeable lithium batteries was demonstrated. The introduction of multiple salts in the electrolyte induced a larger diversity in solvation structures, enhancing lithium-ion diffusivity and the formation of stable interphase passivation layers. A low-concentration dimethyl ether electrolyte with four salts showed enhanced cycling stability and rate capability. These findings highlight the potential of high-entropy electrolytes for lithium batteries and beyond.
