The effect of exposure to RF-EMF from the laboratory simulator of 5G NR base station on physiological parameters and cognitive abilities of male wistar rats of different ages.

In this article, the impact of radiofrequency electromagnetic field (RF-EMF) exposure from a simulated base station for the 5G New Radio (5G NR) telecommunication on rats was studied. The base station affects all age groups of the population, thus, for the first time, the experiment was conducted on male Wistar rats of three different ages (juvenile, adult, and presenile). The base station exposure parameters were chosen according to ICNIRP recommendations for limiting the exposure to radiofrequency electromagnetic field: frequency 2.

Estimation of the Regenerative Potential of para-Tyrosol in the Model of Testicular Insufficiency Caused by Damage to Spermatogonial Stem Cells.

The regenerative properties of p-tyrosol were investigated in a model of testicular insufficiency caused by a toxic effect on spermatogonial stem cells (single administration of paclitaxel in the maximum tolerable dose). Against the background of p-tyrosol administration, we observed an increase in the number of normal spermatogonia and Sertoli cells, stimulation of spermatogenesis, and renewal of the spermatogenic tissue. The treatment with p-tyrosol also led to a decrease in DNA damage in cells of the testicular tissue.

Experimental Study of the Effectiveness of Phenolic Antioxidants in Male Infertility Caused by Pathospermia.

The effect of phenolic antioxidants (dihydroquercetin, p-tyrosol, dibornol) on the morphology, functions, and redox processes in the reproductive cells of male rats was studied on the model of experimental pathospermia. All antioxidants reduced the percentage of degenerative forms of spermatozoa. Dibornol was most effective.

Effect of a water-maze procedure on the redox mechanisms in brain parts of aged rats.

The Morris water maze (MWM) is a tool for assessment of age-related modulations spatial learning and memory in laboratory rats. In our work was investigated the age-related decline of MWM performance in 11-month-old rats and the effect exerted by training in the MWM on the redox mechanisms in rat brain parts. Young adult (3-month-old) and aged (11-month-old) male rats were trained in the MWM.

Dihydroquercetin effects on the morphology and antioxidant/prooxidant balance of the prostate in rats with sulpiride-induced benign hyperplasia.

A course of dihydroquercetin (antioxidant) injections to 5-month-old Wistar rats with sulpiride-induced benign prostatic hyperplasia led to reduction of proliferative activity in the glandular structures and to attenuation of the inflammatory reaction in the tissue. Prostatic antioxidant/prooxidant balance returned to normal after the treatment.
