The ratio of the period of cardiac cycle to the period of vessel autofluctuations is constant in healthy resting humans. This ratio constitutes 1.309 +/- 0.068. The same correlation is observed between the duration of the pneumo-cycle and the period of respiratory arrhythmia. At working and post-constriction hyperemia, there is a resonance in cardiac-respiratory-hemodynamic system that synchronizes the fluctuation processes of its constituent elements and increases the RVG amplitude. The data obtained have been discussed. 相似文献

Experimental data are presented on evaluating the efficiency of auditory perception of the dolphin Tursiops truncatus of tonal signals of different duration and of the fixed energy on the background of Gauss obstacle. The dependence of percepting properties on time characteristics of the signal are stated. A comparative analysis of the efficiency of dolphin auditory system with that of the coordinated filter is carried out. Biological receiving systems are shown to be adaptive. The self-tuning linits of the dolphin auditory system at a given level of the possibility of correct detection are determined. 相似文献

Morphological studies have been made of the neocortical and archicortical structures in the spiny mouse Acomys cahirinus, the only maturely born species from the family Muridae. The data obtained reveal highly developed hippocampus as compared to the neocortex in this mouse, in contrast to relationships found in other mice and rats. 相似文献

Hematopoietic stem cells (HSCs) effectively and continuously replenish the full range of blood-cell populations. Bone-marrow and umbilical-cord blood stem-cell transplantation (SCT) restore hematopoiesis when used in various hematological and oncohematological disorders in adults and children. However, wider clinical application of effective SCT-based approaches is limited by the low number of primitive HSCs in the available biospecimens. Development of effective protocols of HSC expansion in vitro is therefore necessary. In this review, the notion of bone marrow hematopoiesis is discussed as a complex cellular system and a comparative analysis of various methods for HSC expansion in vitro is provided. The review is illustrated by our own data supporting application of various feeder-cell types for human HSC expansion in vitro. 相似文献
