Summary: This study investigates the response and interaction of freshwater biofilm microbial communities to silver nanoparticles (AgNPs). The results show that AgNPs do not significantly affect microbial diversity in the biofilms, but increase the production of extracellular polymeric substances (EPS) and glycerophospholipid metabolism. Scanning electron microscopy reveals distinct structural phenotypes in the biofilms exposed to AgNPs. Overall, this study provides a unique view of how multispecies biofilms respond to the environmental stress of silver nanoparticle exposure.

Summary: This study investigated the adsorption, elimination, and toxicity of silver nanoparticles and silver nitrate in biofilms composed of the model bacterium Escherichia coli and natural mixed-species. The results showed that natural mixed-species biofilms were more tolerant to silver nanoparticles and silver ions than E. coli biofilms, and silver ions were more toxic to both biofilms than silver nanoparticles. The concentrations of certain biomolecules and metabolic enzymes were also found to be significantly different in the two types of biofilms, highlighting the advantages of metal-exposed natural mixed-species biofilms in terms of both structure and metabolic function. These findings contribute to our understanding of the environmental risks of engineered nanoparticles and provide insights into biofilm-based remediation of nanoparticles-contaminated aquatic environments.

Summary: This study designed stable AgNPs that are resistant to surface oxidation and Ag+ ion release. Toxicity studies revealed size- and concentration-dependent effects of AgNPs, with smaller nanoparticle sizes leading to increased mortality and sublethal morphological abnormalities. This study provided valuable insights into the impact of AgNP size on toxicity in the absence of Ag+ ions.

Summary: In this study, a simple and fast synthesis method for silver nanoclusters (AgNCs) was developed. The synthesized AgNCs exhibited fluorescence properties, which could be controlled by various factors. The fluorescence emission of the AgNCs depended on the excitation wavelength. Furthermore, the AgNCs were used as fluorescent probes for the detection of Cr3+ ions.

Summary: The study found that UVB radiation enhanced the toxicity of organophosphorus insecticides on tropical amphibian tadpoles, resulting in higher mortality, increased immobility, and decreased total length. This suggests that UVB radiation may be one contributing factor to the decline in amphibian populations in tropical countries. More field studies in areas with agrochemical presence are recommended for a better understanding of the effects of these stressors on amphibians.

Summary: Teleost fish, as the most diverse group of vertebrates, have diverse digestive anatomical structures and strategies, leading to various host-microbiota interactions. This study focused on the digestive mechanisms and microbiota of agastric short-intestine fish, specifically the Mexican pike silverside, and found that gut microbial diversity decreased in cultivated fish compared to wild fish. Functional metagenomic prediction also showed variations in microbial populations related to amino acid, vitamin, cofactor, and energy metabolism.

Summary: Multimetallic systems are used to develop materials with diverse supported species to enhance their catalytic, antimicrobial activity, etc. This study investigated the changes in nanospecies obtained from ternary Ag+-Cu2+-Zn2+/mordenite systems through thermal reduction and cooling in different atmospheres. Varying the metal content, ratios, and atmosphere during cooling resulted in diverse copper and silver nanospecies. Zinc cations altered the mordenite matrix, producing oxygen defects and surface zinc oxide sub-nanoparticles.

Summary: The thermochemical properties of Al micropowder after exposure to microwave irradiation were investigated. It was found that an increase in the duration of microwave pulses and irradiation time leads to the thermal annealing of the metal particles, and the thermal processes of melting and sintering begin to dominate over non-thermal processes. The specific thermal effect of irradiated Al micropowder oxidation increases significantly compared with the unirradiated powder. The modeling of thermal heating processes of aluminum (Al) micropowder under the action of pulsed microwave radiation has been performed, and the results were compared with experimental results.

Summary: Lipid oxidation in feeds can negatively affect the health and rearing performance of juvenile marine fish. Increasing intake of oxidized lipids decreases survival, growth rate, and liver metabolism, while also altering lipid metabolism and blood cell fragility. These results indicate the importance of proper handling and storage of feeds to maintain their nutrition quality.

Summary: This study evaluated the ability of silver nanoparticles (AgNP) to induce immunogenic cell death (ICD) and their anti-cancer effects in vitro and in vivo. The results showed that AgNP had anti-proliferative effects on CT26 and MCA205 cell lines and could release calreticulin. However, immunization with AgNP-treated tumor cell debris failed to induce a protective immune response in vivo. Further research is needed to explore the combination of AgNP with other ICD inducers to enhance their anti-tumor effect in vivo.

Summary: The current work is a continuation of our studies on the application of metallic silver nanoparticles (AgNPs) to combat antibiotic resistance globally. Fieldwork involving 200 breeding cows with serous mastitis revealed that treatment with Dienomast (TM), an antibiotic-containing drug, reduced E. coli sensitivity to 31 antibiotics by 27.3%, while treatment with AgNPs increased it by 21.2%. This study contributes to efforts in restoring antibiotic efficacy and preserving the availability of antibiotics in the global market.

Summary: This study synthesized silver nanoparticles by irradiation treatment of silver nitrate solution with various stabilizers in a liquid medium and investigated their cytotoxic properties against cancer cells. The results showed that the silver nanoparticles had a dose-dependent cytotoxic effect on tumor cells, and the particles obtained with the combination of polyvinylpyrrolidone and collagen hydrolysate exhibited stronger cytotoxicity compared to samples stabilized with only collagen or only polyvinylpyrrolidone. The AgNPs formulation prepared with a mixture of PVP and PH showed significantly higher activity than other reported formulations.
