Green Synthesized Zinc Oxide Nanoparticles with L. Root Extract and Their Antagonistic Activity Against Oral and Health-Threatening Pathogens.

Unlabelled: For the past few years, the synthesis of zinc oxide (ZnO) and other metal oxide nanoparticles has been carried out using plant tissues, extracts, and other plant parts. The green synthesis of zinc oxide nanoparticles has many advantages over other processes, and the primary areas of application are drug delivery, food additives, and surface coatings. The use of nanoparticles as an alternative antimicrobial agent in the health and biomedical sectors has increased significantly in recent years.

Evaluating the efficacy of a phage cocktail against Pseudomonas fluorescens group strains in raw milk: microbiological, physical, and chemical analyses.

The objective of this study was to investigate the effectiveness of a phage cocktail against Pseudomonas fluorescens group and its effect on the microbial, physical and chemical properties of raw milk during different storage conditions. A phage cocktail consisting of Pseudomonas fluorescens, Pseudomonas tolaasii, and Pseudomonas libanensis phages was prepared. As a result, reductions in fluorescent Pseudomonas counts of up to 3.

Investigation of the constituents of commercially available toothpastes.

Objectives: Toothpaste plays a pivotal role in oral and dental hygiene. This cross-sectional study not only investigates the constituents of toothpastes available in the market and their frequency across different brands but also delves into the potential side effects, irritations, or unfavourable outcomes of these constituents, emphasizing the broader health and environmental implications.

Methods: The largest of the five major chain markets in each district of Istanbul was visited, and adult toothpastes were included in this study.

The Effects of Silver Nanoparticles (AgNPs) on Thermophilic Bacteria: Antibacterial, Morphological, Physiological and Biochemical Investigations.

Since thermophilic microorganisms are valuable sources of thermostable enzymes, it is essential to recognize the potential toxicity of silver nanoparticles used in diverse industrial sectors. Thermophilic bacteria 2Cx, 3CA, 3CA1, FMB1, and FMB2-1 were selected, and their MIC and MBC values were assessed by treatment with AgNPs in a range of 62.5-1500 μg mL.
