Summary: The study identified 53 out of 116 actinobacteria isolates with antagonistic activity against Pythium aphanidermatum, and selected two bioactive Streptomyces isolates (H2 and H3) for further evaluation in controlling damping-off disease in tomato. The in vivo greenhouse experiments demonstrated that these two bioactive Streptomyces strains effectively reduced disease incidence and improved plant performance. Phylogenetic analysis revealed close relations of the strains H2 and H3 to known Streptomyces species, indicating their potential as biocontrol agents against Pythium aphanidermatum.

Summary: This study produced mesoporous silica nanoparticles (MSNs) with a particle size of 20 nm and used a water-soluble chitosan derivative called HTCC to coat the outer surface of MSNs loaded with a pesticide. The results showed that the HTCC coating improved the pesticide loading efficiency and prolonged the release of the pesticide from the MSNs. Greenhouse experiments demonstrated that the pesticide delivered through HTCC-coated MSNs effectively reduced disease severity in tomato plants at a lower concentration compared to direct application of the pesticide.

Summary: Phytophthora sojae is an important pathogen in agriculture that causes Phytophthora root rot (PRR) in soybean crops, leading to significant yield losses. Currently, the most economical control option is the use of host resistance, but this can lead to the adaptation of the pathogen to overcome plant resistance. Therefore, new strategies, particularly the use of biological control agents, are needed.

Summary: This study identified a Bacillus subtilis strain N-18 isolated from the rhizosphere of healthy plants grown in FCRR areas, which produced volatile organic compounds with inhibitory effects on Fusarium oxysporum. Acetoin and 2-heptanol, two active ingredients in the VOCs produced by N-18, were found to reduce the incidence of FCRR in tomato plants. Molecular docking results suggested that acetoin interacts with a hypothetical protein in F. oxysporum.

Summary: An active electrochemical sensor for screening adrenaline (AD) in human fluid samples and pharmaceutical drugs was developed using sulfur-doped carbon microspheres (S-CMS) and irregular-edge carbon stacked sheet (S-CSS) structures. The S-CSS-based sensor exhibited high selectivity and sensitivity with a wide detection range and a low detection limit for AD. It can be used to monitor AD in pharmaceutical drugs and human blood serum with fast response and using highly economic materials at extremely low concentrations.

Summary: The expansion of engineering and development of porous materials from agro-waste-derived for the synthesis of bio-adsorbents as efficient extractors is a significant breakthrough in the economy and environment. This study successfully prepared a novel spongy mesoporous hybrid silica (SMS-L) from wheat straw through dissolution/precipitation methodology. The SMS and SMS-L bio-adsorbents were used to extract/preconcentrate 232Th isotope from Egyptian cataclastic rock (ECR), showing high adsorption capacity depending on the pH value of the extraction process. The research provides important insights into the utilization of sustainable waste and the potential for clean energy applications.

Summary: This study reviewed the trends of fenobucarb usage in Japan between 1969 and 2020 and analyzed its ecotoxicological and health risks in river water. While the amount, residues, and potential hazards of fenobucarb have decreased significantly over the past two decades, it still poses a significant threat to aquatic life in many rivers. However, it does not represent a major risk to human health through water. Therefore, monitoring pesticide usage trends and assessing risks to aquatic organisms and human health are important.

Summary: Glyphosate, the most widely used herbicide globally and in Japan, has raised concerns for its environmental and health effects due to its abundance in surface waters. This study examined the temporal use of glyphosate-based herbicides in Japan from 1989 to 2019, as well as the concentrations of glyphosate in river water. The findings suggest that glyphosate poses moderate threats to the Japanese aquatic environment and human health, emphasizing the need for regular monitoring and reassessment.

Summary: This study aimed to investigate the patho-biochemical toxicity of repeated low oral doses of malathion, metalaxyl, and cymoxanil pesticides on male rats. The results showed that low doses of these pesticides did not cause significant symptoms or histopathological changes in treated rats, while medium and high doses led to adverse signs and symptoms of toxicity. Cymoxanil was found to be the most toxic pesticide, followed by Malathion and metalaxyl. Hepatotoxicity and nephrotoxicity were evident in rats treated with cymoxanil, while neuronal and pulmonary changes were similar across all doses of the pesticides. Overall, this study recommends examining the potential adverse effects of pesticides on animals and humans before their application in agricultural fields.
