The antibacterial activity of the copper for and depends on its state: metalized, chelated and ionic.

The hypothesis that the antibacterial effect of copper depends on its state was tested. It was studied the antibacterial effect of copper applied to the fabric, copper in chelated and free (ionic) forms on the growth intensity of and in the system after a single or "primary" contact. Classical microbiology methods were used.

Improving Resistive Heating, Electrical and Thermal Properties of Graphene-Based Poly(Vinylidene Fluoride) Nanocomposites by Controlled 3D Printing.

This study developed a novel 3D-printable poly(vinylidene fluoride) (PVDF)-based nanocomposite incorporating 6 wt% graphene nanoplatelets (GNPs) with programmable characteristics for resistive heating applications. The results highlighted the significant effect of a controlled printing direction (longitudinal, diagonal, and transverse) on the electrical, thermal, Joule heating, and thermo-resistive properties of the printed structures. The 6 wt% GNP/PVDF nanocomposite exhibited a high electrical conductivity of 112 S·m when printed in a longitudinal direction, which decreased significantly in other directions.

Evaluation of Peripheral Neuropathy in Rat Models of Metabolic Syndrome and Diabetes Mellitus.

The dynamics of nephropathy development in rats with type 2 diabetes mellitus, caused by a high-fat diet and the streptozotocin administration (25 mg/kg), and metabolic syndrome, caused by addition of 20% fructose solution to the diet, was evaluated during the experiment. Models with moderate severity of metabolic changes without significant changes in body weight were obtained after 24 weeks. To study neuropathy severity, the method of electroneuromyography was used; the velocities of motor and sensory excitation propagation along the caudal nerve fibers were measured.

Dihydroquercetin-Loaded Liposomes Change Fibrous Tissue Distribution in the Bleomycin-Induced Fibrosis Model.

The effects of the antioxidant dihydroquercetin (DHQ) were studied in a model of pulmonary fibrosis. DHQ penetration into the lesion was facilitated by encapsulation into liposomes. Pulmonary fibrosis was modeled in rats by intratracheal injection of bleomycin.
