Summary: This study examines the possibility of establishing a Common Treatment Facility (CTF) in Nepal to treat infectious healthcare waste. It conducted a survey in healthcare facilities in Nepalgunj to investigate current practices of waste management and estimate waste generation rates. Different scenarios for the capacity assessment and implementation modality of the CTF are proposed based on waste generation data and fraction of infectious waste. The study aims to provide a sustainable solution for healthcare waste management in rapidly urbanising cities of developing countries.

Summary: This study estimates the carbon emissions from municipal solid waste treatment across 30 Chinese provinces from 2011 to 2020. The results show that technological advances in waste treatment are the main driver of national carbon emissions reduction. Additionally, the impact of policies on carbon emissions changes is further analyzed using the LMDI-PDA model, considering socio-economic factors. The methods and results of this study can provide better decision-making support for national and provincial carbon emissions control policies targeting MSW treatment.

Summary: By comparing the environmental impacts of anaerobic digestion-pyrolysis and pyrolysis-anaerobic digestion integrations with single anaerobic digestion and pyrolysis technologies for organic solid waste, it was found that anaerobic digestion-pyrolysis has the least environmental impact, while pyrolysis-anaerobic digestion exhibits the heaviest environmental burden. Hence, the anaerobic digestion-pyrolysis integration is considered the top priority for treating organic solid waste from an environmental perspective.

Summary: A novel type of green and non-sintered lightweight aggregates (LWAs) was successfully prepared using quarry tailings and fly ash as raw materials. The effects of curing time and temperatures on the properties of LWAs, such as compressive strength, water absorption, and pore structures, were systematically investigated. SEM linking nanoindentation technology was applied to analyze the microstructure and micromechanical properties of LWAs. The prepared LWAs exhibited high compressive strength, low apparent density, and low water absorption, making them potentially suitable for structural applications.

Summary: Solid waste management has become a significant global concern due to the increase in per capita waste generation. Improper waste management practices have had a significant negative impact on the environment. Plasma pyrolysis technology offers an environmentally safe approach to converting solid waste into energy, producing high-quality syngas/hydrogen, and minimizing solid residue. This review examines the current status of plasma pyrolysis technology and its application in treating various types of solid waste, including hazardous waste. It also explores the compositions and uses of the resulting solid residue and syngas, as well as the design and generation sources of plasma reactors. Additionally, the cost estimation and challenges of this technology are discussed, along with recommendations to make it a viable option on a larger scale.

Summary: The aim of this study was to investigate the immunological and antimicrobial properties of breast milk in pregnant women with or without vaginal yeast infections. The study found that concentrations of IL-10, IgA, IgM, IgG, EGF, and TGF-alpha were similar in both groups. However, breast milk from women in the W-group who were below 31 years old had a higher concentration of EGF compared to the WO-group. Additionally, breast milk from the WO-group exhibited higher anti-Candida properties. Correlation analysis showed that the concentration of TGF-alpha in breast milk positively correlated with the concentrations of IL-10 and IgA in the W-group. These findings suggest that while breast milk from women with vaginal infections during pregnancy may not hinder Candida growth, other immuno-modulatory bioactives may compensate for this protective effect.

Summary: Date (Phoenix dactylifera) seed can be a potential source of natural antioxidants. Innovative green and low temperature antioxidant recovery techniques, such as supercritical fluid (SFE) and subcritical (SubCO(2)) extractions using CO2 as a solvent, can improve the yields and quality of antioxidant extracts. This study compared SFE, SubCO(2), and Soxhlet techniques for enriching antioxidants in extracts from different date seed varieties. The results showed that SFE and SubCO(2) methods extracted significantly higher levels of phenolics, flavonoids, anthocyanins, and carotenoids compared to Soxhlet. In vitro evaluation also demonstrated that SFE and SubCO(2) extracts had promising antioxidant properties, making them potential candidates for functional and nutraceutical applications.

Summary: In this study, N-phenylbenzamide (N-PBA) was synthesized using solvent-pair mixtures containing hydrogen bond donor and hydrogen bond acceptor to explore the replacement/limitation of hazardous dipolar aprotic solvents in amide drug synthesis. Different pure solvents and mixed solvents were selected based on their Kamlet-Taft parameters and GSK 2016 health-safety scores. The yields of N-PBA were evaluated using high-performance liquid chromatography (HPLC) under an amide coupling system at 25 degrees C. The results showed that safe solvent mixtures could be used to avoid/limit hazardous dipolar aprotic solvents and significantly improve the yield of N-PBA.

Summary: Vancomycin-resistant Enterococci (VRE) genes are bacteria strains that are resistant to the antibiotic vancomycin. They exhibit phenotypic and genotypic variations and pose significant issues for hospitalized patients. This review summarizes methods for detecting VRE strains and explores the potential use of electrochemical DNA biosensors for detecting VRE genes. However, no information was found on the development of electrochemical biosensors for VRE genes, only for vancomycin-susceptible bacteria.

Summary: We compared the microbiota profiles of breast milk from women with and without vaginal yeast infection during pregnancy. Breast milk from women with vaginal yeast infection exhibited higher alpha diversity across different taxonomic levels. The composition of breast milk from the two groups showed marginal differences at certain taxonomic levels. Our findings suggest that vaginal infection during pregnancy may affect breast milk composition, but it may not pose a threat to infant growth and development.
