RESUMO

The work characterizes the intestinal microbiota of patients with ischemic stroke, including the spectrum, frequency and number of microorganisms, as well as the spectrum and amount of gas signaling molecules secreted by lactobacilli. It was found that in patients with ischemic stroke, the frequency of the main representatives of normal microflora, Bifidobacterium spp., Lactobacillus spp., Escherichia coli, decreased in 2-3 times, and the same time the prevalence of Clostridia spp., Bacillus spp., Peptostreptococcus spp., Klebsiella spp. increased in 2-3 times; yeast like fungi C. albicans was isolated in 25% of cases. Lactobacilli isolated from the intestinal microbiota of patients with ischemic stroke were represented by a wide variety of species: L. rhamnosus, L. fermentum, L. plantarum, L. brevis, L. pentosus, L. curvatus, L. salivarius. In most cases, they did not produce NO, they released CO 2 times less compared to healthy people. The most active NO producers - L. plantarum, CO - L. rhamnosus.

RESUMO

The microbiome of oral cavity in healthy people and patients with periodontitis was analyzed to determine their adhesive properties and the ability to form biofilms. The study involved 2 groups: healthy, 18 people, and an experimental group, 20 patients with chronic generalized periodontitis moderate severity of the disease. The average age of the studied people was 35-45 years. Material - dental plaque, scraping from the mucous membrane of the back of the tongue, the contents of the periodontal groove and periodontal pocket, as well as oral fluid. The main method of diagnostic was bacteriological. The average adhesion index (AAI) was used to determine adhesion level of microorganisms to epithelial cells of oral cavity's mucous membrane. The microbiota's ability to form biofilm was tested on glass and plastic surface. The microbiota of oral cavity of patients with periodontitis was characterized by decrease in the frequency of bacteria of the genera: Streptococcus, Peptostreptococcus, Peptococcus, and an increase in Staphylococcus aureus, Veillonella spp., Bacillus spp. The microbiota of the oral cavity of patients with generalized periodontitis has a greater ability to adhere to the cells of the mucous membrane than in healthy people, while their ability to form biofilms and exhibit pathogenic properties is enhanced. The biofilm formation of microorganisms in healthy and sick people differs both on glass and on plastic surfaces.

RESUMO

Methods for evaluating the functional state of the body and physical fitness of men and women in the second period of adulthood have been analyzed in the article. The timely diagnosis of these indicators allows to optimally distribute exercises and adjust them to each trainee. Indicators of the functional state of the body and physical fitness should be analyzed in combination, as it allows to obtain more accurate results. Materials. Analysis of methods for evaluating the physical and functional state of the body is presented in the article. Methods. The following research methods have been used in the article: analysis and systematization of scientific and methodological literature, pedagogical experiment, testing, and statistical data processing. Results. The research has been conducted with the purpose of analyzing the existing methods for evaluating the physical and functional state of the body. The results of a comprehensive research of the indicators of the functional state and physical fitness are more accurate because the human factor is taken into account (the participants could not accurately meet the targets in the calculation). The results have led to a conclusion about the need to use a wide range of methods for diagnosing the functional state and physical fitness. Conclusion. Conditions for correct performance should be honored in functional tests and physical fitness tests, as this influences the reliability of the data. The results have led to a conclusion about the need to use a wide range of m

RESUMO

The motor activity belongs to controllable factors that influence human health because it ensures disease prevention. Analysis of scientific publications has revealed that motor activity of adult people is insufficient; this leads to the development of hypodynamia and worsens health. The level and nature of motor activity should correspond to the peculiarities of the body (age, gender, functional state, physical fitness, etc.). This problem requires the study of the relationship between the motor activity of the adult men and women and their indicators of physical fitness and functional state of the body. The relationship between the motor activity and indicators dependent on it has been reviewed in the article. The impact of the motor activity on the functional state of the body and physical fitness has been determined. The results have led to a conclusion that the motor activity of adults should be analyzed along with the study of indicators of functional state and physical fitness.

RESUMO

The yield of alpha particles in neutronless fusion reactions 11B +p in plasmas produced by picosecond laser pulses with the peak intensity of 2 x 10(18) W/cm2 has been observed. Experiments were carried out on the "Neodymium" laser facility at the pulse energy of 10-12 J and pulse duration of 1.5 ps. The composite targets 11B + (CH2)n were used. The yield of 10(3) alpha particles per pulse has been observed. The energy spectrum of alpha particles contains two maxima: at 3-4 MeV and at 6-10 MeV . The first of these peaks corresponds to the secondary alpha12 particles at the decay of the intermediate first excited state of 8Be, whereas the second peak demonstrates generation of alpha1 particles in the reaction 11B +p with the production of this excited state. Simultaneous measurements of neutrons result in zero yield, which proves the observation of neutronless fusion reactions in our experiments.

RESUMO

We have observed spectra from highly charged zinc ions in a variety of laser-produced plasmas. Spectral features that are Na - and Mg -like satellites to high- n Rydberg transitions in the Ne -like Zn XXI spectrum are analyzed and modeled. Identifications and analysis are made by comparison with highly accurate atomic structure calculations and steady state collisional-radiative models. Each observed Zn XX and Zn XIX feature comprises up to approximately 2 dozen individual transitions, these transitions are excited principally by dielectronic recombination through autoionizing levels in Na - and Mg -like Zn19+ and Zn18+. We find these satellites to be ubiquitous in laser-produced plasmas formed by lasers with pulse lengths that span four orders of magnitude, from 1 ps to approximately 10 ns. The diagnostic potential of these Rydberg satellite lines is demonstrated.

RESUMO

Spectra in the 7.10 to 8.60 A range from highly charged copper ions are observed from three different laser-produced plasmas (LPPs). The LPPs are formed by a 15-ns Nd:glass laser pulse (type I: E(pulse)=1-8 J, lambda=1.064 microm), a 1-ps Nd:glass laser pulse (type II: E(pulse)=1 J, lambda=1.055 microm), and a 60-fs Ti:sapphire laser pulse (type III: E(pulse)=800 mJ, lambda=790 nm). The spectra of high-n (n
