Summary: This review article discusses the adsorptive characteristics of neem biomass for the removal of heavy metal ions and dyes from water. Neem biomass, with its availability and various functional groups, is able to extract heavy metal ions and dyes from water through electrostatic interactions. Factors such as pH, adsorbate concentration, adsorbent dosage, contact time, particle size, and temperature also affect the adsorptive capacity of the biomass. Neem biomass shows affinity to Langmuir and Freundlich isotherm models and follows pseudo-second-order kinetics. The article also suggests that the adsorptive potential of neem biomass can be enhanced through chemical modification.

Summary: The use of Bacillus licheniformis cells and their metabolites shows potential as a low-cost and environmentally friendly alternative for synthetic compounds in mineral beneficiation techniques. Selective flotation of barite from quartz was achieved, with the cell-assisted separation proving more effective than metabolite-facilitated flotation in both single mineral and mixed samples. The study also demonstrated the ability of B. licheniformis cells to selectively enhance particles hydrophobicity and act as a successful bio-collector.

Summary: This study introduced a novel application strategy to turn conventional spent mushroom substrate (SMS) into renewable biochar SMS in mushroom production. The renewable SMS demonstrated greater mushroom yields and faster fruiting time compared to conventional SMS. Biochar retained substrate moisture and reduced nutrient loss, contributing to the increased mushroom yields. Further analyses confirmed the food safety of oyster mushrooms cultivated using renewable SMS. The economic analyses indicated a higher output-to-input ratio for renewable SMS compared to conventional SMS. Additionally, the basic properties of renewable SMS and its effect on mushroom growth remained consistent even after repeated use.

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: Polylactic acid (PLA) fibre is a renewable and biodegradable synthetic polymer that has gained attention in textiles. However, its dyeing process faces challenges, and a waterless dyeing method using disperse dyes is being explored as an alternative. This study investigated the waterless dyeing of PLA fibre using different disperse dyes and decamethylcyclopentasiloxane (D5) as the medium. Optimal dyeing process conditions were determined, and it was found that disperse dyes with a monoazo structure were most suitable for PLA waterless dyeing. The research provides a basis for developing suitable dyes for waterless dyeing of PLA using D5.

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: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
