Summary: Currently, e-waste is being overproduced and insufficient recycling programs exist, leading to negative environmental and health impacts. A systematic review of the literature reveals that small IT and Telecommunication equipment are the most studied e-waste classes, with cell phones, printed circuit boards, and LCD panels being commonly cited. Toxic heavy metals such as Pb and Cd, as well as polybrominated diphenyl ethers, are frequently associated with e-waste toxicity. Bioassays were identified as effective tools for assessing the toxic potential of e-waste in soil and water. The review also highlights the need for collaborative studies and government regulation to address methodological difficulties and evaluate the long-term effects of e-waste exposure.

Summary: This study demonstrates that metformin can suppress cancer cell proliferation and colony formation by increasing genotoxic stress. The effect is dependent on the glucose environment and is weakened in high glucose conditions. Additionally, metformin can increase genotoxicity in non-cancer cells, suggesting that its effects may vary in different cell types.

Summary: This study evaluated the biodegradation of dimethylformamide (DMF) and bioremediation of laboratory wastewater (LWW) co-contaminated with poly-cyclic aromatic hydrocarbons (PAHs) by a methylotrophic enrichment culture. The culture efficiently degraded high concentrations of DMF and removed DMF, phenanthrene, pyrene, and BaP in the LWW. The efficacy of bioremediation was further confirmed through genotoxicity assays and oxidative stress assays.

Summary: The study found dose-related accumulation of Pb in the offspring brain after developmental exposure, leading to sustained neural damage and neuroinflammatory responses in adulthood. Suppressed differentiation of type-3 neural progenitor cells was observed, resulting in an increased number of immature granule cells in adulthood. Additionally, induction of cellular senescence of SGZ cells due to Pb genotoxicity was suggested.

Summary: Acrylamide is a food-borne toxicant generated during thermal processing of starchy, fatty, and proteinous foods. To reduce acrylamide levels, mitigation techniques involve using low precursor starting materials, modifying process conditions, and applying post-process interventions. Enzyme-assisted reduction of acrylamide has been found effective in maintaining bio-active compounds without impacting final product properties.

Summary: Fish have limited capability to utilize carbohydrates compared to mammals. In this study, zebrafish fed with omnivorous and herbivorous diets showed better glucose homeostasis due to enrichment of the commensal bacterium Cetobacterium somerae, which produces acetate. Dietary supplementation of acetate promotes glucose utilization in zebrafish, and the beneficial effect of acetate and C. somerae on glucose homeostasis is mediated through parasympathetic activation. These findings suggest potential strategies for improving fish carbohydrate utilization.

Summary: The purpose of this study was to determine the toxicological and pharmacokinetic properties of sucralose-6-acetate, a structural analog of the artificial sweetener sucralose. It was found that sucralose-6-acetate is genotoxic and raises significant health concerns regarding the safety and regulatory status of sucralose itself. Sucralose-6-acetate also impairs intestinal barrier integrity and inhibits members of the cytochrome P450 family.

Summary: This study compared the culture method using sodium acetate and glucose as organic carbon sources with autotrophy in Haematococcus pluvialis. In the 12-day culture, mixotrophy with sodium acetate and glucose increased biomass by 40.4% and 77.1% respectively compared to autotrophy, but the mechanisms were different. Mixotrophy with glucose increased biomass by directly supplying substrate and ATP to the TCA cycle while inhibiting photosynthesis. Gene expressions related to glycolysis and carbon fixation pathway were confirmed in autotrophy and mixotrophy with glucose and acetate. The proposed metabolism in mixotrophy with acetate and glucose was analyzed through autotrophic and heterotrophic metabolism.

Summary: Mobile Ad hoc Networks (MANETs) are popular for their flexibility in setting up anytime and anywhere, but using Transmission Control Protocol (TCP) in these networks raises serious performance issues. In this paper, a novel algorithm called TCP-LoRaD is proposed to overcome the problems of packet losses and poor performance in noisy channel conditions. Simulation results show that TCP-LoRaD offers higher throughput and lower end-to-end delays compared to TCP-WELCOME under medium to high traffic loads.

Summary: The present study synthesized rGO nanosheets and TiO2 nanoparticles by a green method using aloe vera and gram seeds, respectively. A simple microwave-assisted approach was used to prepare the TiO2/rGO nanosheets composite. The as-prepared materials were characterized using SEM, TEM, XRD, FTIR, XPS, and Raman spectroscopy. The TiO2/rGO-NS composite exhibited a sheet-like nature and was used as the cathode with a carbon cloth substrate. The electrochemical properties of the materials were studied using cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy. The TiO2/rGO-NS composite coated carbon cloth cathode showed a maximum specific capacitance (599.9 Fg(-1)) and energy density (83.31 Whkg(-1)) at a current density of 1 Ag-1.

Summary: We synthesized a graphene oxide supported In2O3/CeO2 ternary nanocomposite for enhanced photodegradation and electrochemical sensing. The nanocomposites exhibited efficient photocatalytic degradation of Congo red (CR) and methylene blue (MB) dyes, with degradation rates reaching 94% in 130 min and 95% in 91 min, respectively. The composite also showed excellent electrochemical activity, with a sensitivity of 4.635 mu A mM-1 cm-2 and a low detection limit of 0.036 mu M for the sulfa drug sulfamaxole. The composite's increased degradation and redox behavior can be attributed to enhanced photon absorption, efficient charge transfer, and suppression of charge recombination.

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.
