Nociceptors: Their Role in Body's Defenses, Tissue Specific Variations and Anatomical Update.

The human body is constantly under the influence of numerous pathological factors: both external and internal. These factors can be potentially harmful and are perceived as such with a specialized nervous system subunit: the nociceptive system. The functional unit of the nociceptive system is the nociceptor.

Methods: The study enrolled 77 students from Sechenov University with overweight and obesity aged from 17 to 23 years.

Cobalt in athletes: hypoxia and doping - new crossroads.

Cobalt is an essential trace element that is known to mimic hypoxia and hypoxic training. Inorganic Co compounds are capable of Hypoxia-inducible factor-1 (HIF-1) activation, resulting in up-regulation of gene expression including erythropoietin (Epo). Experimental studies have demonstrated that Co treatment may increase hypoxic tolerance of different tissues, improve muscle metabolism and exercise performance.
