    Clause is devoted to consideration of theoretical models of adaptable modes of generation and stability of heart, as nonlinear dynamic dot source. Consideration is limited by research of time dynamics of an electrocardiogram. The comparative description of corresponding mathematical dynamic models available on today is lead. Necessity of creation of as much as possible general model which are based physical laws of processes of the response of heart on external influence is revealed.Настоящая Ρ€Π°Π±ΠΎΡ‚Π° посвящСна Ρ€Π°ΡΡΠΌΠΎΡ‚Ρ€Π΅Π½ΠΈΡŽ тСорСтичСских ΠΌΠΎΠ΄Π΅Π»Π΅ΠΉ Π°Π΄Π°ΠΏΡ‚Π°Ρ†ΠΈΠΎΠ½Π½Ρ‹Ρ… Ρ€Π΅ΠΆΠΈΠΌΠΎΠ² Π³Π΅Π½Π΅Ρ€Π°Ρ†ΠΈΠΈ ΠΈ устойчивости сСрдца, ΠΊΠ°ΠΊ Π½Π΅Π»ΠΈΠ½Π΅ΠΉΠ½ΠΎΠ³ΠΎ динамичСского Ρ‚ΠΎΡ‡Π΅Ρ‡Π½ΠΎΠ³ΠΎ источника.

    Under the analysis of statistical data in experiments we try to understand and check how systolic and diastolic pressure depends on seasons.

    Time, in relativistic terms in the context of the speed of light, depends not only on the speed of an observer as a whole. Several different time scales within an observer also relate differently to cycles in the cosmos, all of them assessed by spectral peaks with non-zero amplitudes. Thus, in many physiological, psychological, sociological, epidemiological and physical environmental variables, an inferential statistical transdisciplinary array of spectra unfolds, with reciprocal cycles as components with overlapping 95% confidence intervals in ever broader and diverse chronomes (time structures) that underlie the genetics of an evolving biosphere, representing a phylogenetic memory, and accumulating an as-yet fragile noosphere, to be recognized by its interactions with its cosmos, to be rendered compatible with human survival.ΠŸΡ€Π΅Π΄ΡΡ‚Π°Π²Π»Π΅Π½ΠΈΠ΅ ΠΎ Π²Ρ€Π΅ΠΌΠ΅Π½ΠΈ Π½Π΅Ρ€Π°Π·Ρ€Ρ‹Π²Π½ΠΎ связано с Космосом ΠΈ процСссами, происходящими Π²ΠΎ ВсСлСнной.

    On the basis of experimental research we described nine typical (nonspecific) responses of the damaged heart which are initially protective and adaptive but are able to have a pathogenetic character under some certain conditions. These typical responses are as follows: shortening of the effective refractory period of the myocardium, cardiomyocyte mitochondrion swelling, activation of lysosomal apparatus, initial intensification of lipolysis, hypertrophy of cardiac muscle, formation of collagen muffs around blood vessels due to intoxication, functional deafferentation of the heart, changes in the intensity of cardiomyocyte apoptosis, rearrangement of cardiac chronostructure. The represented results can be used as a basis to elaborate some new effective methods of prophilaxis and treatment of heart diseases caused by different etiological factors.На основании ΡΠΊΡΠΏΠ΅Ρ€ΠΈΠΌΠ΅Π½Ρ‚Π°Π»ΡŒΠ½Ρ‹Ρ… исслСдований Π²Ρ‹Π΄Π΅Π»Π΅Π½ΠΎ Π΄Π΅Π²ΡΡ‚ΡŒ Ρ‚ΠΈΠΏΠΎΠ²Ρ‹Ρ… (нСспСцифичСских) Ρ€Π΅Π°ΠΊΡ†ΠΈΠΉ ΠΏΠΎΠ²Ρ€Π΅ΠΆΠ΄Π΅Π½Π½ΠΎΠ³ΠΎ сСрдца, ΠΏΠ΅Ρ€Π²ΠΈΡ‡Π½ΠΎ ΡΠ²Π»ΡΡŽΡ‰ΠΈΡ…ΡΡ Π·Π°Ρ‰ΠΈΡ‚Π½ΠΎ-ΠΏΡ€ΠΈΡΠΏΠΎΡΠΎΠ±ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹ΠΌΠΈ, Π½ΠΎ ΠΌΠΎΠ³ΡƒΡ‰ΠΈΡ… ΠΏΡ€ΠΈ ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½Π½Ρ‹Ρ… ΠΎΠ±ΡΡ‚ΠΎΡΡ‚Π΅Π»ΡŒΡΡ‚Π²Π°Ρ… ΠΈΠ³Ρ€Π°Ρ‚ΡŒ ΠΈ ΠΏΠ°Ρ‚ΠΎΠ³Π΅Π½Π΅Ρ‚ΠΈΡ‡Π΅ΡΠΊΡƒΡŽ Ρ€ΠΎΠ»ΡŒ: ΡƒΠΊΠΎΡ€ΠΎΡ‡Π΅Π½ΠΈΠ΅ эффСктивного Ρ€Π΅Ρ„Ρ€Π°ΠΊΡ‚Π΅Ρ€Π½ΠΎΠ³ΠΎ ΠΏΠ΅Ρ€ΠΈΠΎΠ΄Π° ΠΌΠΈΠΎΠΊΠ°Ρ€Π΄Π°, Π½Π°Π±ΡƒΡ…Π°Π½ΠΈΠ΅ ΠΌΠΈΡ‚ΠΎΡ…ΠΎΠ½Π΄Ρ€ΠΈΠΉ ΠΊΠ°Ρ€Π΄ΠΈΠΎΠΌΠΈΠΎΡ†ΠΈΡ‚Π°, активация лизосомного Π°ΠΏΠΏΠ°Ρ€Π°Ρ‚Π°, ΠΈΠ½ΠΈΡ†ΠΈΠ°Π»ΡŒΠ½ΠΎΠ΅ усилСниС Π»ΠΈΠΏΠΎΠ»ΠΈΠ·Π°, гипСртрофия сСрдСчной ΠΌΡ‹ΡˆΡ†Ρ‹, ΠΎΠ±Ρ€Π°Π·ΠΎΠ²Π°Π½ΠΈΠ΅ Π²ΠΎΠΊΡ€ΡƒΠ³ ΠΌΠΈΠΎΠΊΠ°Ρ€Π΄ΠΈΠ°Π»ΡŒΠ½Ρ‹Ρ… сосудов ΠΊΠΎΠ»Π»Π°Π³Π΅Π½ΠΎΠ²Ρ‹Ρ… ΠΌΡƒΡ„Ρ‚ ΠΏΡ€ΠΈ интоксикациях, Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΎΠ½Π°Π»ΡŒΠ½Π°Ρ дСаффСрСнтация сСрдца, ΠΈΠ·ΠΌΠ΅Π½Π΅Π½ΠΈΠ΅ интСнсивности Π°ΠΏΠΎΠΏΡ‚ΠΎΠ·Π° ΠΊΠ°Ρ€Π΄ΠΈΠΎΠΌΠΈΠΎΡ†ΠΈΡ‚ΠΎΠ², пСрСстройка хроноструктуры сСрдца.

    The study aims to explore the possibilities of magnetic resonance (MR) imaging in detecting lesions of anatomical structures of shoulder joint. We present the results of examinations of the patients with instability of the shoulder joint. These examinations were carried out by means of a MR tomography using a high-field MR-tomograph with magnetic field intensity of 1.5 Tl. The results of the MRI diagnosis were compared with intraoperative data of diagnostic arthroscopy. Definitive diagnosis allows us to define further patient management, to correct surgery planning, to decrease sick-lists duration and improve quality of patient’s life.ЦСлью исслСдования являСтся ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΠ΅ возмоТностСй ΠΌΠ°Π³Π½ΠΈΡ‚Π½ΠΎ-рСзонансной (МР) Ρ‚ΠΎΠΌΠΎΠ³Ρ€Π°Ρ„ΠΈΠΈ Π² выявлСнии ΠΏΠΎΠ²Ρ€Π΅ΠΆΠ΄Π΅Π½ΠΈΠΉ анатомичСских структур ΠΏΠ»Π΅Ρ‡Π΅Π²ΠΎΠ³ΠΎ сустава.

    Daytime Exposure to Blue Light Alters Cardiovascular Circadian Rhythms, Electrolyte Excretion and Melatonin Production

    Artificial light is characterized by certain features of its impact on the body in terms of its spectral distribution of power, duration of exposure and intensity. Short waves, perceived as blue light, are the strongest synchronizing agent for the circadian system. In the present work, we investigated the features of the circadian rhythms of blood pressure (BP), heart rate (HR), the excretion of electrolytes and the secretion of melatonin in normotensive (Wistar–Kyoto) and hypertensive (SHR) rats under the action of monochromatic blue light in the daytime period. It was found that the exposure of Wistar–Kyoto rats to monochromatic blue light was accompanied by a significant decrease in nighttime and 24 h systolic BP. The most remarkable changes are characteristic of the HR in SHR rats under monochromatic light. A significant decrease in HR in each time period was found, but the predominance of nighttime over daytime values remained in SHR animals. There was also a significant increase in the mesor of the HR in SHR rats. Additionally, the amplitude of diastolic BP and HR, as well as the range of oscillations in HR, were significantly increased compared with the standard light pattern. In contrast to SHR rats, the regulation of the circadian rhythms in Wistar–Kyoto rats was more flexible and presented more changes, which may be aimed at the adaptation of the body to environmental conditions. For Wistar–Kyoto rats, an increase in the level of excreted electrolytes was observed under the action of monochromatic light, but no similar changes were found in SHR rats. For Wistar–Kyoto rats, a significant decrease in the urine concentration of aMT6s in the daytime and nighttime periods is characteristic, which results in the loss of the circadian rhythm. In SHR rats, there was a significant decrease in the nighttime content of aMT6s in the urine, while the daytime concentration, on the contrary, increased. The obtained data demonstrate that prolonged exposure to monochromatic blue light in the daytime period affects the circadian structure of the rhythms of the cardiovascular system, the rhythm of electrolyte excretion and the production of epiphyseal melatonin in wild-type and hypertensive animals. In SHR rats, the rhythms of BP and HR exhibit a more rigid pattern

    More on the Tensorial Central Charges in N=1 Supersymmetric Gauge Theories (BPS Wall Junctions and Strings)

    We study the central extensions of the N=1 superalgebras relevant to the soliton solutions with the axial geometry - strings, wall junctions, etc. A general expression valid in any four-dimensional gauge theory is obtained. We prove that the only gauge theory admitting BPS strings at weak coupling is supersymmetric electrodynamics with the Fayet-Iliopoulos term. The problem of ambiguity of the (1/2,1/2) central charge in the generalized Wess-Zumino models and gauge theories with matter is addressed and solved. A possibility of existence of the BPS strings at strong coupling in N=2 theories is discussed. A representation of different strings within the brane picture is presented.Comment: 26 pages, 2 figures, 1 reference added, typos corrected, Sec. 9.3 expanded.
