Adrenergic receptor mechanisms of functional sympatholysis in the regulation of regional blood flow in response to epinephrine after 5-day cold acclimation
BACKGROUND:. During muscle contraction, blood flow in the working muscles increases tens of times due to the mechanisms of sympatholysis. However, there are no studies that would quantitatively describe the effect of epinephrine on arterial alpha-adrenergic receptors during sympatholysis against the background of 5-day cold adaptation. AIM: Objective. To study the effect of five-day cold adaptation on the adrenoreactivity of muscle arterial vesse…
Impact of сold adaptation on reactivity of muscular arteries to epinephrine in functional sympatholysis
Background: Functional sympatholysis is determined as a tenfold increase in blood flow in the muscular arteries following the muscle contraction. This is explained by various mechanisms. However, there are no works on quantitative analysis of the pharmacokinetics and pharmacodynamics of the epinephrine effects on the arterial α-adrenergic receptors in sympatholysis before and during the cold adaptation.Aim: To study the effect of the 30-day cold …
Differences between male and female university students in sleepiness, weekday sleep loss, and weekend sleep duration
INTRODUCTION: Women and men experience sleep differently and the difference in intrinsic desire for sleep might underlie some of the observed male-female differences. The objective of this cross-sectional questionnaire study of university students was to determine male-female differences in self-reported sleepiness and sleep-wake patterns. METHODS: Five questionnaires were completed by 1650 students at four Russian universities. RESULTS: Compared…
Ecological Factors Associated With Fluctuations in the Incidence of Neoplasms in Children
Introduction: Despite the increasing volume of knowledge on oncogenesis, the year-to-year fluctuations in the incidence of neoplasms remain poorly explained. Neoplasms in children
Falling Asleep Process in Human Listening to Different Types of Monotonous Sound
Development of non-invasive sleep-aid tools requires paying attention to techniques reducing and stabilizing fall-asleep time. Otherwise, all attempts to affect posterior sleep make no sense. The aim of current study was to compare effectiveness of listening through stereo earphones to three types of monotonous sound as one of those techniques. Namely, the sound engendering so-called "binaural beats" (BB), the sound containing ordinary ("monaural…
Age Self-Assessment of 55-64 Years Old Women as an Express Method for Determining the Parameters of Life Quality in the Circumpolar Region
The purpose of this study consisted in the comparative evaluation of the quality of life parameters (QOL) among the female residents of the Arkhangelsk region aged 55-64 years old with different levels of the age self-assessment. The study group (SG) of 104 women reported that they felt at their calendar age (CA) and older. The comparison group (CG) of 252 women - subjectively felt younger than their CA for 5 years or more. For the women surveyed…
Use of Geometric Methods of Analysis of Video-Oculographic Data to Assess the Functional Condition of a Person
Objective. In article describes two original algorithms for the analysis of video-oculographic data and analyses the effectiveness of these algorithms to assess the current functional condition of a person. One of the algorithms is designed for estimating macrosaccades curvature and the other - to evaluate the smoothness of target tracking. Both algorithms are based on geometric methods of videooculographic data processing. Methods. The assess of…
Age Characteristics of Postural Control Components in Women 55-64 Years Old
The purpose of the study was to reveal age characteristics of the components of postural control in women 55-64 years old. Computer dynamic stabilometrical complex «Smart Equitest Balance Manager» was used for the comprehensive evaluation of the equilibrium function in elderly women. The following tests were used: Sensory Organization Test (SOT), Motor Control Test (MCT), Rhythmic Weight Shift (RWS). On the basis of the analysis of postural contr…
Seasonal Changes of External Respiratory Parameters in Skiers of Mass Categories in the Conditions of Russian North
The study results of lung volume seasonal changes in skiers of mass categories in the conditions of European North are presented. Respiratory system study was carried out in September, January, April and July in the same group of 38 men skiers aged 18-22 (middle age: 19,6 (19,2; 21,7)), born and permanently residing in Arkhangelsk (64°32'n.l., 40°32'e.l.) and Severodvinsk (64°34'n.l., 39°51'e.l.). Survey sample had experience in cross-country ski…
Postural-Motor Control Characteristics in Older Female Fallers
The paper presents data on the characteristics of a postural-motor control (PMC) in female fallers 65-74 years old (twice or more fallers during a year). Evaluation of PMC parameters was carried out using computer posturographic (stabilometric) complex «Balance Master». «Sit to stand» test analysis showed a rate decrease in the average rise index (p = 0,009) and a rate increase in the average speed of the gravity center (GC) oscillation (p = 0,00…
Influence of Climatic and Geographical Conditions on Anthropometric and Functional Indices of Students
The study of the anthropometric characteristics and functional state of lungs of the students from Peoples' Friendship University of Russia of the South-East Asia and the middle zone of Russia and the functional state of their lungs showed the presence of significant correlation between the anthropometric indicators and forced vital capacity of lungs. It was found that among students with reduced functional reserve, this correlation was weak, and…
