A complex of hygienic, clinical, statistical and experimental studies established the relationship, magnitude, nature, and mechanism of changes in the body of girls who are engaged in petrochemical industry and in contact with the occupational factors of current petrochemical production. The most significant and prognostically poor factors include disturbances in the formation and realization of reproductive function (a menstrual cycle, pregnancy course, labor, postpartum period, posterity health), which were experimentally evidenced (gonadotoxic, embryotropic, mutagenic, and teratogenic effects were found to be shown by a number of hydrocarbons in concentrations not exceeding the allowable ones).

This study introduces a novel approach to enhance the antibacterial properties of UIO-66 by incorporating both Thymol and ZnO nanoparticles within its framework which represents a significant advancement like exhibiting a synergistic antibacterial effect, providing a prolonged and controlled release, and mitigating cytotoxicity associated with the release of free ZnO nanoparticles by combining these two antimicrobial agents within a single, well-defined metal-organic framework. UIO-66 frameworks are investigated as carriers for the natural antimicrobial agent, Thymol, and ZnONPs offering a novel drug delivery system for antibacterial applications. Results demonstrated 132, 90, 184, and 223 nm sizes for UIO-66, ZnONPs, UIO-66 encapsulated Thymol, and UIO-66 encapsulated both Thymol and ZnONPs, respectively.

A practical transition metal-free approach for the selective benzylation of NH-sulfoximines has been disclosed by using simple elemental iodine as the catalyst and -butyl hydroperoxide (TBHP) as the terminal oxidant. Comparing with known methods for the construction of -benzylated sulfoximines, our protocol shows broad substrate scope with respect to both diarylmethanes and alkylarenes, and can be conducted in air with good functional group tolerance.

Antibiotic residue detection plays an important role in protecting human health, but real-time, rapid, and highly sensitive detection is still challenging. Herein, gold and silver nanoparticles (Au-Ag NPs) were grown on the surface of optical fibers and a 50 nm thick gold film was deposited on the sensor's surface to fabricate the Au-Ag@Au fiber SPR sensor. The sensitivity of the sensor reached 3512 nm per RIU in the refractive index range of 1.
