Summary: The combination of VO2+ in the anolyte with Pd/C at the anode is introduced for the first time in a formic acid fuel cell to enhance HCOOH electrooxidation. The VO2+/Pd catalyst combination establishes a stepwise reaction pathway involving HCOOH dehydrogenation and V3+ electrooxidation to regain VO2+. The fuel cell with the VO2+/Pd combination exhibits a peak power density of 341.3 mW cm(-2) and a stable power density higher than 30 mW cm(-2).

Summary: Herein, we report a cobalt N,N-bidentate complex catalyzed reductive formylation of N-heteroarenes for the generation of N-formyltetrahydroquinoline (FTHQ) derivatives. Formic acid was used as a transfer hydrogenation reagent, which is safe, abundant, and easy to handle. This work represents the first homogeneous system for the reductive formylation of N-heteroarenes, where the metal ligand cooperated dehydrogenation is crucial for the success of this transformation. Deuteration labeling experiments and Hammett analysis were conducted, suggesting a plausible mechanism.

Summary: Exposure to pollutants can cause damage to the eyes of aquatic organisms. Zebrafish is a commonly used model to study ocular toxicity and has shown morphological changes, retinal damage, and abnormalities in visual signal processes. The underlying mechanisms involve thyroid hormone signaling, retinoic acid signaling, and retinal glucose metabolism. This review discusses the phenotypes and signaling pathways associated with ocular toxicity from contaminants, detection methods, and a predictive model for potential ocular toxicity.

Summary: During the 2015-2016 Chinese Antarctic Research Expedition, a study was conducted on Particulate-bound mercury (PBM) in the boundary layer. The study found a significant latitudinal gradient in PBM, with higher levels over the Northern Hemisphere influenced by both continental and oceanic sources. Over the Southern Ocean, PBM levels were extremely low, while elevated PBM was observed across the Antarctic Ice Sheet, particularly at Dome A. The study also revealed the role of inland Antarctic snow in influencing atmospheric PBM concentrations over the Antarctic coastal seas.

Summary: Succinate, an intermediate of the TCA cycle, is crucial in mitochondrial metabolism, energy production, and is also considered a signaling molecule in metabolism and hepatic diseases. Its downstream signaling pathway through GPR91 leads to various intracellular responses, including succinylation, ROS production, HIF-1 alpha stabilization, and significant impact in cellular metabolism due to its role in the TCA cycle. Understanding the signaling mechanisms of succinate in hepatic fibrosis, metabolic reprogramming, inflammatory or immune responses, and carcinogenesis is of great interest. This review aims to provide the current understanding of succinate in mediating metabolism, inflammatory and immune responses in liver diseases, with the aim of establishing a molecular basis for therapeutic strategies.

Summary: We investigate the behavior of solutions to a scalar Delay Differential Equation (DDE) with periodic switching between two constant values. This equation naturally arises in structured vector populations involved in the spread of various vector-borne diseases in a periodically changing environment. We examine the influence of two different time lags and the switching time on the existence and patterns of periodic solutions, with a specific focus on multi-cycles within the prime period.
