BACKGROUND The human femur is commonly considered as a subsystem of the locomotor apparatus with four conspicuous levels of organization. This phenomenon is the result of the evolution of the locomotor apparatus, which encompasses both constitutional and individual variability. The work therein reported, therefore, underlies the significance of observing… (More)
BACKGROUND The human femur is the subsystem of the locomotor apparatus and has got four levels of its organization. This phenomenon is the result of the evolution of the locomotor apparatus, encompassing both constitutional and individual variability. The main aim of this investigation was to study the organization of the human femur as a system of… (More)
Two low-molecular-weight compounds were isolated from the parotid gland secret of the toad Bufo bufo, which by absorption spectra and HPLC-MS/MS chromatography data correspond to di- and trimethyl derivatives of serotonin (5-hydorxytryptamine): bufotenine (confirmed by counter synthesis) and bufotenidine (5-HTQ). In experiments on competitive radioligand… (More)
The HCK8 was found to inhibit the field search behaviour in rats. Administration of the peptide impairs formation and reproduction of a habit within 1 hour and 24 hrs. The data obtained suggest an important role of the brain monoaminergic systems in the mechanisms of the HCK8 effect upon learning and memory.
Changes in the fatty acid composition of sweat lipid were studied in persons whose activity was associated with military service. There were significant changes in essential fatty acids of sweat lipids, which made it possible to use this noninvasive biological object as a criterion for rating dysadaptive processes in armed forces personnel.
