The research clinical and instrumental methods of examination of athletes related to the process of intervertebral disk degeneration and stenosis.

Objective: Aim: To determine the level structure of the graph model of the system of clinical and instrumental indicators of athletes with herniated intervertebral discs complicated by spinal stenosis, and to determine the regression model for these indicators.

Patients And Methods: Materials and Methods: This observational study involved 64 athletes (14 - rugby players, 16 - handball players, 15 - basketball players, 19 - football players) with intervertebral disc herniation, complicated by stenosis of spinal canal. Research methods: visual method to evaluate the likelihood of a data set's normal distribution; correlation and regression analysis; method for determining the ordinal function of a graph through the application of an adjacency matrix, specif i cally utilizing Demucron's algorithm.

Flavonoid content and antioxidant activity of Artemisia vulgaris L. "hairy" roots.

We investigated the effect of Agrobacterium rhizogenes-mediated transformation on antioxidant activity of Artemisia vulgaris "hairy" roots. It appeared that transformation may increase flavonoid content as well as DPPH-scavenging activity and ability to reduce Fe as compared to the non-transformed plants. Some "hairy" roots accumulated flavonoids up to 73.

Study of artemisinin and sugar accumulation in Artemisia vulgaris and Artemisia dracunculus "hairy" root cultures.

We studied the effect of genetic transformation on biologically active compound (artemisinin and its co-products (ART) as well as sugars) accumulation in Artemisia vulgaris and Artemisia dracunculus "hairy" root cultures. Glucose, fructose, sucrose, and mannitol were accumulated in A. vulgaris and A.
