In this study, we analyzed the putative association between the ¡308 G/A polymorphism in the promoter region of the tumor necrosis factor (TNF) a gene (rs1800629) and chronic inflammatory arthritis in the Bulgarian population. A case-control study was carried out on 58 patients with ankylosing spondylitis (AS), 108 rheumatoid arthritis (RA) patients and 177(More)
In summation and averaging of sections of the EEG of sensorimotor cortex of both cerebral hemispheres recorded during human static effort of definite duration, a complex of negative-positive oscillations was observed. These oscillations appear before the beginning of the effort, accompany its execution and finishing and are also recorded after cessation of(More)
The data are presented on potentials revealed by averaging buman EEG sections recorded during termination of a motor act. The potential consisted of two components: fast positivity and slow negative wave. The complex under study was named "final" or "relaxation" potential. The latency of the "final" potential and that of the muscle relaxation were linearily(More)
Readiness potential (RP) has been defined in EEG recorded in the sensorimotor human cortex during tracing movements. RPs which appear prior to the tracing of different programmes, differ in the time of their appearance, duration and amplitude. Dependence has been established between the RP amplitude and tracing movements latency: movements latency is lower(More)
