Associations between the parameters of central nervous and cardiovascular systems and arsenic content in 13-15 year old teenagers
Effects of low-level arsenic exposure on central nervous and cardiovascular systems were examined in 13-14 year old (n=30) and 14-15 year old (n=25) teenagers. Hair arsenic content in all examined was within normal limits (X-ray spectrophotometry). Correlations were determined between the arsenic content and spectral power of high-frequency EEG rhythms, EEG-potentials and parameters of the rheography (0,32<rs <0,50; 0,005<р<0,09). Neurophysiologic and cardiodynamic arsenic effects were more significant in 13-14 year old teenagers.

Heart rate variability in subjects with different types vegetative regulation under the influence of controlled respiration with individually selected frequency (Part I)
The article presents a complex study of heart rate variability (HRV) in subjects with different types of vegetative regulation under the influence of controlled breathing (CB) with individually selected frequency. The study found that the CB, the frequency of which corresponds to the maximum peak power at low frequencies, the spectrum of cardiac rhythm is a powerful way to control heart rhythm, and functional status (FS), cardio-respiratory system of subjects with different types of autonomic regulation, as evidenced by optimization of HRV, increased tolerance of the cardiovascular system to submaximal exercise and increase the synchronization of cardiac and respiratory rhythms.

The dispersive analysis of indicators of heart rate variability conditions under the influence of controlled breath with individually fitted frequency
Quite high frequency of human papillomavirus in clinical samples – 30% of clinical specimens had positive  PCR result. The greatest frequency of genotypes were 18, 31, 33, 35, 39, 45, 52, 58, 59, 67, a relatively low  frequency of occurrence reported for type 16. The frequency of different genotypes of human papillomavirus  infection depends on age and blood group of patients.

Materials of the comparative study of the leafcutter bees nesting (Hymenoptera, Megachilidae,  Megachile Latr.). Part I. Nest buildings diversity
The analysis of nesting modes diversity of wild solitary bees of the genus Megachile was carried out. All the bees of  the genus (their nesting is known) build fully component cells. More often nest cells are located in ready hollows of  various origins, more seldom in hollows that are gnawed out by a female bee in the ground or some other substrate.  Only bees of the subgenus Chalicodoma build free cells on the surface of the substrate. The representatives of 16  subgenera of this genus use slices of leaves or more seldom – slices of flower petals for cell building. Female bees of  7 subgenera use only slices. Others also use a chewed leaf material (4) or wet soil (6), resin (1), sand (1) or sawdust  (1). The representatives of 3 subgenera mostly use the soil; sometimes they add resin, leaf mastic. It should be noted  that the nesting of the bees of the genus Megachile is weakly studied. The modes of nesting are known for the  representatives of less than a half of the subgenera. General concepts for the further observation of a bee leafcutter  nesting are defined. List of nest parameters that are the most interesting for the observation is given.

Peculiar features of feeding plants’ anatomical structure influenced by rust fungus Melampsora populnea (Pers.) P. Karst. (Uredinales)
The influence of the rust fungus Melampsora populnea (Pers.) P. Karst on the anatomic structure of vegetative  organs of feeding plants Mercurialis perennis L. and Populus niger L. is studied. Local and entophytic parasite’s disposition in the tissues of host plants is revealed, the phenomenon of tissues’ hypertrophy and  deformation of organs of M. perennis are found. It can be adjudged that under the influence of the pathogen on  M. perennis, the delignification of sclerenchyma’s cells and a weaker development of perimedullary zone are  observed. The necroses of the epidermis, leaf’s mesophyll along with the complete loss of necrotic tissue are  noticed at the place of the lesion in M. perennis. It is shown that under the influence of infection in leaves of  P. niger at the stage of telio- and urediniosporulation, a decrease in the thickness of sklerenhyma layer of  vascular bundles and destruction of leaf’sanatomy are observed.

Modulation of microcirculation processes with the help of low millimeter radiation
Using the method of laser Doppler flowmetry it was shown that low-intensity EHF EMR has a gross effect on the  processes of microcirculation in human skin, wich expressed in a change of nonoscillatory and oscillatory  characteristics of basal blood flow and indices of microvascular tone. Momentary influence of EHF EMR leads to a  local decrease in peripheral resistance and domination of nutritional blood flow in the shunt one against depression in  favor of which indicate an increase in the amplitudes of myogenic and endothelial tissue blood flow oscillations  indicate the against background of a decrease myogenic tone and indicator shunt only in the localization of EHF  exposure. Repeated exposure EHF EMR has a shiking effect on the change of nonoscillatory and oscillatory  indicators of passive and active regulation factors of microcirculatory processes resulting in an increase in the  production of vasodilators, decrease in peripheral resistance in the arterioles and precapillares, increase blood flow in  the microvascular against the background improved venular outflow. In the mechanisms of action of low-intensity  EHF EMR on microcirculatory processes the main role belongs to endothelium-dependent, endotheliumindependent myogenic and neurogenic components of the regulation of tissue blood flow.

Dynamics of development of playing manipulation at calf of Steller sea lion in  ontogenesis
There’ve been studied play manipulative behavior in sea lion calves (a male and a female) born in Oceanarium  during their evolvement (up to one year old). It’s been found that play manipulation with objects includes  actions typical of feeding behavior (grasping, holding in teeth, biting, throwing up in air and patting). While  playing with objects and fish the calves generated a series of actions typical of the closing stage of feeding  behavior. The results obtained indicate an important role of play manipulation with environmental objects in  forming feeding behavior habits in sea lion calves.

The study of phytotoxic influence of various DNOC concentrations on the seeds of  Helianthus annuus L.
Influence of different concentrations of BI-58 on the generative system of Allium cepa L. was investigated. It  is set that low concentrations (0,05 and 0,1 ml/l) do not possess a palynotoxic effect. High concentrations (0,2  and 0,4 ml/l) the medium toxic made influence on the generative organs of Allium cepa L., bringing to the  reliable increase of products of sterile pollen with broken morphologic structure.

Features of interaction and level of secretion of estrogen and glucocorticoids in various  phases menstrual cycle sportswomen
Investigated levels of secretion and feature of interaction of glucocorticoids and an estrogen during a menstrual  cycle of sportswomen and at performance of a physical activity of various capacity. The highest level of cortisol  secretion observed during menstruation, and the smallest just before menstruation. Estradiol peak observed in the  phase of ovulation. During the application of physical impact was an increase in the level of tonic secretion of  estradiol and cortisol in the phase of ovulation, and reduced levels of cortisol in the premenstrual phase in 100%  while increasing the level of estradiol secretion, which can be considered as a compensatory reaction in the  direction of steroidogenesis to enhance glucocorticoid function. Identified two types of reactions associated with  decreased and increased levels of tonic secretion of estradiol in comparison with the rest while using the exercise  in other phases of the cycle showed varying degrees of fatigue athletes and can be used as a criterion for  determining the degree of fatigue in the different phases of the menstrual cycle.
