Summary: Strategies for depleting carbon dioxide (CO2) from flue gases are urgently needed, and carbonic anhydrases (CAs) can contribute to solving this problem. This current study examines four recombinantly produced CAs from different organisms, namely CAs from Acetobacterium woodii (AwCA or CynT), Persephonella marina (PmCA), Methanobacterium thermoautotrophicum (MtaCA or Cab), and Sulphurihydrogenibium yellowstonense (SspCA). The highest expression yields and activities were found for AwCA and PmCA. AwCA showed high stability in a mesophilic temperature range, while PmCA proved to be exceptionally thermostable. These results indicate the potential to utilize CAs from anaerobic microorganisms for CO2 sequestration applications.

Summary: High carbon dioxide concentration in the atmosphere calls for eco-friendly mitigation strategies. Carbonic anhydrase (CA) immobilization can enhance its stability and enzyme recycling, but there is limited mass transfer between gaseous CO2 and the active center of immobilized CA. This review focuses on improving the mass transfer process to increase the efficiency of enzymatic CO2 capture for industrial applications.

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: This study investigated the effects of TCS exposure on kidney function in mice. The results showed that TCS caused renal injury, oxidative stress, inflammation, and fibrosis in a dose-dependent manner. Metabolite analysis revealed lipid accumulation and defective fatty acid metabolism in TCS-exposed mouse kidney, which may contribute to renal function impairment.

Summary: Many mammalian tissues have specific cellular arrangements under stress stimulus, but conventional 3D encapsulation fails to replicate these arrangements accurately, so advanced cellular arrangement approaches are needed. In this study, a novel 3D prestress bioprinting approach is developed, using static sustained tensile stress, molecular chain orientation, and slow crosslinking in bioink to guide tissue construction. The semi-crosslinking state of the bioink provides excellent elasticity for applying stress on cells during the printing process. After printing, the bioink gradually crosslinks and maintains the applied stress force to induce cell-orientated growth. This approach allows for directional arrangement of multiple cell types, with adjustable internal stress in the hydrogel filament, and has potential applications in engineering skeletal muscles, tendons, ligaments, vascular networks, or combinations thereof.

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.
