Summary: The study focuses on finding new microorganisms that can produce antibiotics in Egypt's harsh environments. 280 bacterial isolates were tested against pathogenic bacteria, with 52 isolates exhibiting antagonistic properties. Mutants with increased antibiotic production were obtained through mutagenesis.

Summary: With the development of the laver industry, the lack of germplasm resources has become a serious problem. In order to increase genetic diversity and develop more germplasm sources, a mutant library was constructed using ethyl methanesulfonate (EMS)-mutagenized archeospores. The mutant library consisted of 1860 haploid thalli, which were evaluated for their phenotypic traits. This research not only provides a practical reference for the construction of mutant libraries for other seaweeds but also serves as a valuable resource for functional genomics research and laver breeding.

Summary: In this study, a whole-exome sequencing (WES) procedure was developed in tobacco to characterize EMS-induced mutations in a test population, revealing a high number of single nucleotide variants. The amount of mutations detected by WES was 93.5% of those detected by whole-genome sequencing, while requiring significantly less sequencing data, making it a cost-effective tool for high-throughput mutation identification in tobacco.

Summary: Induced mutation is an effective breeding strategy widely used in the development of elite plant varieties. In this study, a novel mutant population of soybeans was constructed using ethyl methanesulfonate to improve the variety of edamame. The TILLING method was employed to identify DNA mutations in the mutant populations, leading to the discovery of mutants with early flowering and harvest dates. These mutants can serve as DNA markers and are detectable using high-resolution melting analysis.

Summary: This study estimated the EC content in 145 alcoholic beverages in Korea, with stone fruit-containing beverages showing higher EC levels. Soju and beer were found to be the main contributors to EC exposure in the Korean population. The risk of EC exposure differed between average drinkers and heavy drinkers in the Korean population.

Summary: This study found an association between the BDNF gene rs6265 polymorphism and the risk of dyslexia, and that copper exposure could interact with rs6265 to increase the risk of dyslexia.

Summary: This study emphasizes the importance of addressing the complex regional air pollution problem dominated by particulate matter (PM) and ozone (O-3). The findings suggest that PM1 has a stronger association with daily mortality compared to PM2.5, PM10, and O-3. The study also reveals that co-exposure to PM and O-3 increases the risk of mortality, with higher levels of exposure to both PM (especially PM1) and O-3 leading to the greatest risk. These results provide a scientific foundation for implementing relevant standards and regulatory interventions.

Summary: Zucchini yellow mosaic virus (ZYMV) causes serious damage to cucurbit crops worldwide and can be spread by various means. Through EMS mutagenesis, resistant bottle gourd lines were developed, with the M-4 line showing stable resistance and potential for use in watermelon rootstock development and resistance gene exploration.

Summary: This study proposes a regulatory screening approach to evaluate pesticide allocation factors (AFs) for different exposure pathways. By integrating various models, the study estimates the human intake of pesticide residues from crops, livestock products, and environmental media. The results show that crop exposure contributes significantly to pesticide exposure, while legacy pesticides with high lipophilicity and low degradability mainly expose through environmental compartments.

Summary: This study found that arsenic exposure is associated with an increased risk of hypertension, and arsenic metabolism and folate concentrations also play a role in hypertension risk. The results also suggest a significant interaction between high red blood cell (RBC) folate and high urinary total arsenic (UTAs) with low urinary dimethylarsinic acid (DMA%) on hypertension risk.

Summary: Exposure to thallium (Tl) is associated with an increased risk of early embryonic arrest (EEA), especially in combination with polymorphisms of mitochondrial DNA (mtDNA) gene. High Tl exposure level plays a leading role in EEA when interacting with mtDNA 16,519 gene polymorphism. These associations may be attributed to the impact of Tl exposure or gene polymorphism on oogenesis and early embryonic development in vitro.
