Children of a Secondary Polytechnical school of rubber and plastics were studied. The task aimed at tracing the immunological reactivity of the young generation in the conditions of the chemical industry. The following methods were used: reaction for reactivity of the neutrophylic leucocytes, defining of hemoglobins G, M, E, establishing the complement in serum, the skin autoflora condition, assessment of the microbic saliva content. No significant deviation, expressing decrease of the immunologic reactivity of the organism of the schoolchildren during their training in industrial conditions were established.

Objective: To evaluate the influence of in situ acid erosion on the structural and optical properties of nanoparticulate bisacrylic resin with different surface treatments, evaluating surface roughness (Ra), knoop microhardness (KHN), color change (ΔE, ΔL, ΔC, ΔH), contrast (CR) and translucency (TP).

Methods: Eighty specimens were made (n = 10 per group) and the following surface treatments were applied: U-unpolished; A-polishing with Astropol rubber tips (Ivoclar); S-Biscover LV surface sealant (Bisco) and S-Palaseal surface sealant (kulzer). For the in situ experiment, 10 volunteers wore an intraoral appliance containing eight specimens (two specimens per experimental group), with only one specimen from each experimental group being subjected to the acid process.

Reline, which is composed of choline chloride and urea in a molar ratio of 1:2, is the first and most extensively studied deep eutectic solvent (DES). In certain applications, reline is blended with organic solvents, dimethyl sulfoxide (DMSO) in most cases, to gain improved properties. Therefore, it is crucial to have a profound understanding of the impact of DMSO on the dynamics and structures of the species in the binary mixtures.

Electronic skins endow robots with sensory functions but often lack the multifunctionality of natural skin, such as switchable adhesion. Current smart adhesives based on elastomers have limited adhesion tunability, which hinders their effective use for both carrying heavy loads and performing dexterous manipulations. Here, we report a versatile, one-size-fits-all robotic adhesive skin using shape memory polymers with tunable rubber-to-glass phase transitions.

Ethnomedicine exhibits potential in developing affordable effective antidiabetic agents. This work aimed to explore the antidiabetic properties of latex extract both in vivo, utilizing alloxan-induced diabetic rats, and in vitro, through -amylase enzyme testing. Additionally, it sought to formulate optimal effervescent granules derived from the extract.
