Summary: Plant-derived methyl benzoate (MB) is a scent and aroma that can be used as an alternative pesticide to control insect pests. This study investigated the molecular mechanisms of the beetle Tribolium castaneum's response to MB. The results showed that MB had dose-dependent toxicity to all developmental stages of the beetle, with larvae being the most resilient and eggs being the most susceptible. RNA-seq analysis identified differentially expressed genes involved in chitin biosynthesis, energy metabolism, nervous action, and metabolic detoxification. Additionally, molecular dynamics revealed that OBP99b could stably bind with MB.

Summary: Radio frequency plasma (RFP) is a reliable and cost-effective method for controlling insect pests in stored food products. The sensitivity of Tribolium castaneum to RFP was tested using argon (Ar) and helium (He) gases, with He RFP being more efficient. The optimal exposure time for complete mortality of all stages was found to be 90 seconds with He RFP.

Summary: The use of plant extraction products from Oeneanthe pimpinelloides seeds as insecticide control for packaging materials was investigated, specifically targeting the flour beetle Tribolium castaneum. The seeds were extracted using methanol and the hexane extract was separated from the methanol extract using liquid-liquid extraction method. The chemical composition of each sample was determined and the fractions were impregnated on filter paper for insecticide testing against Tribolium castaneum. The results showed that the hexane fraction had a higher mortality rate compared to the methanol fraction.

Summary: Selenium nanoparticles (SeNPs) can be synthesized by Lactobacillus casei ZK-AS 1.1482 and have antimicrobial activity against Pseudomonas fluorescens. The synthesized SeNPs were amorphous with sizes ranging from 52 to 103 nm and were stabilized by proteins, polysaccharides, and lipids on the surface. SeNPs inhibited the growth of P. fluorescens by decreasing the number of living bacteria and altering cellular functions. The expression of specific genes related to cell membrane integrity was affected by SeNPs treatment. Biogenic SeNPs have the potential to be used as a novel antimicrobial agent in the food industry.

Summary: Many pathogens commonly infect birds through the respiratory tract, leading to respiratory disorders and significant financial losses in the poultry industry. Viral pathogens, such as avian influenza virus, Newcastle disease virus, infectious bronchitis virus, and avian pneumovirus, are particularly severe. Bacterial pathogens, including Mycoplasma gallisepticum, Staphylococcus, Bordetella avium, Pasteurella multocida, Riemerella anatipestifer, Chlamydophila psittaci, and Escherichia coli, also cause serious respiratory infections in poultry. This review provides an updated summary of the evidence for widespread poultry respiratory pathogens, along with possible control and prevention methods.

Summary: Feed accounts for the majority of poultry farming costs, with animal protein being the most expensive component. Fishmeal, the traditional animal protein source in poultry feed, is costly and reduces profit. Silkworm pupae, with their high nutritional content and suitable amino acid profile, have potential as an alternative protein source.

Summary: The effectiveness of the zero-valent iron activated persulfate (Fe0/PS) system in removing Bisphonel AF (BPAF) was systematically evaluated in this study. The optimal conditions for the removal of 30.0 mu M BPAF were at pH = 3.0 and [PS] = [Fe0] = 3.0 mM, resulting in a 94.4% removal rate within 60 minutes. The presence of Cl- accelerated the removal of BPAF due to the release of Fe2+ and the formation of reactive chlorine species (RCS). Thirteen degradation products were identified, and various transformation pathways were considered. When Cl- was present, six new chlorinated byproducts were also generated.

Summary: Natural diatomite frustules were used to obtain zeolitized diatomite and cellulose fibrous/zeolitized diatomite composite, which exhibited enhanced encapsulation capacities for the oxaliplatin drug. The encapsulation reactions followed pseudo-first order kinetic and Langmuir isotherm. The CF/ZD composite had a notably higher effective encapsulation site density than ZD and D, and each effective site could accommodate up to 3 molecules of OXPL in vertical forms. The release profiles showed slow and controlled release properties, and the cytotoxic effects on HCT-116 cancer cell lines were enhanced.

Summary: The kaolinite sheets were delaminated into nanotubes (KNs) through sonication-induced chemical processes. These KNs were used as substrates for ZnO nanoparticles (ZnO/KNs) synthesized through microwave-based techniques. Compared to separate ZnO and KNs phases, as well as commercially used ZnO, the ZnO/KNs structure exhibited enhanced antioxidant and antidiabetic properties due to the positive influence of KNs on surface area, interfaces, charge separation, and agglomeration properties. It demonstrated remarkable scavenging efficiencies for various radicals and strong inhibition effects on enzymes related to diabetes. The antidiabetic activity of ZnO/KNs was comparable to or slightly higher than acarbose, making it a recommended alternative to commercially used drugs.

Summary: The chitosan matrix was used to synthesize ZnO and Ce-doped ZnO nanoflowers. The hybrid structures showed enhanced antioxidant and antidiabetic activities due to the synergetic effect of the components. Ce-doped ZnO nanoflowers exhibited higher activities than ZnO nanoflowers and ZnO/CH composite. The Ce-ZnO/CH composite showed remarkable scavenging efficiencies for various radicals and strong inhibition effects on enzymes related to diabetes.

Summary: This study investigated the use of FeS-activated persulfate (PS) combined with permanganate (KMnO4) for the treatment of PCB-contaminated soil. The FeS/PS system showed a stronger degradation effect on PCBs compared to other systems. Addition of KMnO4 further improved the degradation efficiency. The oxidation of PCBs was found to be influenced by various reactive species. Six main reaction pathways were proposed based on identified intermediates and theoretical calculations. The FeS/PS/KMnO4 system effectively reduced the ecotoxicity of PCBs in soil.
