Are effects of the symmetric and asymmetric tonic neck reflexes still visible in healthy adults?
No full textItem does not contain fulltextWhen a cat's head is rotated in a transverse plane to one side, the legs on that side of the body extend, while on the other side, they flex (asymmetric tonic neck reflexes ATNR). On the contrary, when the head is rotated in a sagittal plane both legs flex when the head flexes, and extend when the head extends (symmetric tonic neck reflexes STNR). These reflexes have also been found in newborn babies and are thought to be a motor primitive, which is suppressed later in life. Still, using a test in which children sit on hand and knees, the ATNR and STNR can be found in children up to 9 years of age. This may suggest that these reflexes may still be involved in motor control in these children. Whether this is also the case in full-grown adults has thus far only been studied using coarse methods. Thus, for the current study, we set out to measure in detail whether the ATNR/STNR can still be evoked in healthy adult subjects. We measured 10 subjects who were asked to sit on their hands and knees while (1) their head was rotated left and right by an experimenter, (2) their head was flexed and extended by an experimenter. Kinematics was registered using a Vicon system. Elbow and head angles were detrended, and a regression analysis was performed, to investigate the effects of head angle on elbow angle. Results clearly showed the existence of the ATNR and STNR in adult subjects. A next step will be to assess the effects of the ATNR and STNR during everyday motor control tasks, such as making head rotations while driving a bike

Abstract
The objective of this experiment was to establish sex-related differences in the parameters of bioimpedance spectroscopy of the Wistar rat’s bodies in the experimental metabolic syndrome (endocrine-salt model).
Sexual dependencies of bioimpedance measurements in intact animals have been determined for the first time: males have higher amount of total fluid, but lower one of total fat. The intra/extracellular fluid balance in males is characterized with ratio 2:1, while in females is the other one - 1:1.
For the first time the formation of the metabolic syndrome has already been determined on the seventh day in females which lead to decreasing in the percentage of total fat and to changing of the intra / extracellular fluid balance to ‘male’ type - 2:1. The last one should be considered as a sign of intracellular hyperhydration. In males the examined parameters have been being within the control values throughout 21 days of experiment.
Key words: bioimpedance spectroscopy; sex-related differences; metabolic disorders; corticosteroids; rats
Markets and Democracy in Russia
No full textThe paper looks into convergence of Russian institutions with those of other democratic, free-market-oriented states, and considers definitions of "normalcy" that incorporate the concepts of free market, democracy, and government efficiency.The author provides an estimate of Russia s institutional convergence to the standards of the G7 and the Big Five group of large, middle-income countries that includes Brazil, China, and India.In some areas Russia outperforms "Big Five" countries, in others it trails behind.Finally, public mistrust, corruption, and inefficient governance in Russia are discussed in light of the Putin administration s current reform policies

No full textBakalaura darbā „ES pilsoņa tiesības uz veselības aprūpi Eiropas Savienības dalībvalstīs saistībā ar brīvo pakalpojumu apriti” autors ir izvirzījis mērķi izpētīt Eiropas Savienības pilsoņa tiesības uz pārrobežu veselības aprūpi. Autors bakalaura darbā ir analizējis normatīvos aktus, Eiropas Savienības Tiesas spriedumus un dažādu autoru domas par veselības aprūpi Eiropas Savienībā.
Darba gaitā autors izpētīja Eiropas Savienības pilsoņa tiesības uz veselības aprūpi un konstatēja, ka problēma pārrobežu veselības aprūpes jomā tiek mazināta ar Eiropas Eiropas Parlamenta un Padomes 2011. gada 9. marta direktīvu 2011/24/EK „par pacientu tiesību piemērošanu pārrobežu veselības aprūpē” kā arī Eiropas Savienības Tiesas spriedumiem.
Autors analizējot Eiropas Savienības normatīvo regulējumu nonāca pie secinājuma, ka pārrobežu veselības aprūpes pārāk plaša un brīva izmantošana var apdraudēt valsts ekonomiku un veselības aprūpes infrastruktūru. Darba gaitā autors piedāvā iestrādāt papildus nosacījumus tam, kādiem kritērijiem iestājoties, Eiropas Savienības pilsonis var iegūt tiesības uz valsts apmaksātu pārrobežu veselības aprūpi, kā arī pamatot domu, ka pārāk liberāla pārrobežu veselības aprūpes pakalpojumu izmantošana var kaitēt dalībvalsts ekonomikai un sagraut tās nacionālo veselības aprūpes sistēmu.In the bachelor paper „The EU citizen's right to health care in the Member States relating to the free movement of services” the author has set a goal to explore the European Union citizen's right to cross-border health care. The author has analyzed the laws and regulations of the European Court judgments and various authors' views on health care in the European Union.
The author studied the European Union citizen's right to health care and found that the problem of cross-border health care are being undermined by the European Union Parliament and Council directive 2011/24EC “on the application of patients' rights in cross-border healthcare”, accepted on March 9th 2011, as well as the judgments of the European Union Court of Justice.
After analyzing the European Union's regulatory framework the author concluded that the cross-border health care was too broad and free use may endanger the national economy and health care infrastructure. During the work, the author proposes to incorporate additional conditions to which the criteria for joining the European Union citizen can acquire the right to state-funded cross-border health care, as well as emphasize the notion that too liberal usage of cross-border health care services can harm member states economy and destroy its national health care infrastructure as such

Patterns of the SARS-CoV-2 epidemic spread in a megacity [Закономерности эпидемического распространения SARS-CoV-2 в условиях мегаполиса]
No full textThe purpose of the study is to analyze patterns demonstrated by the COVID-19 epidemic process in a megacity during the increase, stabilization and reduction in the incidence, and to evaluate the effectiveness of the epidemic prevention measures. Materials and methods. The comprehensive study incorporating epidemiological, molecular-genetic and statistical research methods was conducted to analyze the spread of SARS-CoV-2 in Moscow during the COVID-19 pandemic. Results and discussion. It was found that the exponential growth in COVID-19 cases was prevented due to the most stringent control and restrictive measures deployed in Moscow to break the chains of SARS-CoV-2 transmission and due to people who were very disciplined in complying with the self-isolation rules. The analysis of the dynamics in detection of new COVID-19 cases showed that in a megacity, the impact of social distancing and self-isolation would become apparent only after 3.5 incubation periods, where the maximum length of the period is 14 days. It was discovered that the detection frequency of SARS-CoV-2 RNA in relatively healthy population and its dynamics are important monitoring parameters, especially during the increase and stabilization in the COVID-19 incidence, and are instrumental in predicting the development of the epidemic situation within a range of 1-2 incubation periods (14-28 days). In Moscow, the case fatality rate was 1.73% over the observation period (6/3/2020-23/6/2020). Conclusion. The epidemiological analysis of the COVID-19 situation in Moscow showed certain patterns of the SARS-CoV-2 spread and helped evaluate the effectiveness of the epidemic prevention measures aimed at breaking the routes of transmission of the pathogen. © 2020 Izdatel'stvo Meditsina.
