[Comparative study of dental and psychological status in athletes of Olympic teams and the population of Moscow]. / Stomatologicheskii i psikhologicheskii statusy u sportsmenov olimpiiskikh sbornykh i naseleniya Moskvy.

AIM: To compare dental and psychological status in athletes of Olympic teams and the population of Moscow. MATERIALS AND METHODS: In order to study the features of the dental rehabilitation of Olympic athletes, a comparative study of the dental and psychological status of 132 athletes was carried out when they were included in the Olympic teams and 104 residents of Moscow of the same age. Clinical x-ray examination was supplemented by «Hamburg testing¼ of the masticatory apparatus and psychological examination using common questionnaires and scales. RESULTS: The study revealed a difference in the status of dental status, the results of the "Hamburg Testing" and psychological examination between athletes of the Olympic reserve and the population of Moscow of the same age. Athletes showed a lower quality of previous treatment of caries and its complications, insufficient oral hygiene, more frequent detection of chronic periodontitis, diseases of the oral mucosa, secondary deformations of the dentition, pathological phenomena of the temporomandibular joint, masticatory apparatus dysfunction according to the results of the "Hamburg Testing". Athletes also established psychological status features: higher rates of reactive and personal anxiety, the presence of depressive manifestations, lower quality of sleep and quality of life. CONCLUSION: The revealed patterns can provoke muscle hyper-tone and muscular-articular dysfunction of the maxillofacial region, which must be taken into account during the dental rehabilitation of athletes of Olympic teams.

[Interaction investigation of trypsin inhibitor from sea anemone Radianthus macrodactylus with proteases].

The interaction of inhibitor VJ (InhVJ), isolated from sea anemone R. macrodactylus, with different proteases was investigated. The following enzymes were tested: serine proteases (trypsin, alpha-chymotrypsin, plasmin, thrombin, kallikrein), cysteine protease (papain) and aspartic protease (pepsin). Inhibitor VJ interacted only with trypsin and 6-chymotrypsin. Kinetic and thermodynamics parameters of intermolecular complexes formation were determined: KD = 7,38 x 10(-8) M and 9,93 x 10(-7) M for pairs InhVJ/trypsin and InhVJ/alpha-chymotrypsin, respectively.
