the relationship between relaxation and rhythmic exercises with regard to functional neuroplasticity mechanism is a subject that has been studied in recent researches. the purpose of this study was to investigate the effect of rhythmic exercises on the depth of relaxation in national judo athletes. 30 male athletes of national judo team were randomly selected and divided into three groups: cont...

The effect of yoga and relaxation changes in psychophysiological parameters in response to the stress of examination in 75 medical students was studied. Initially five parameters (anxiety level, heart rate, blood pressure, galvanic skin resistance and choice reaction time) were recorded, a month before the examination and on the day of examination. Students were then randomly divided into 3 gro...

BACKGROUND Measurement of systolic and diastolic function in animal models is challenging by conventional non-invasive methods. Therefore, we aimed at comparing speckle-tracking echocardiography (STE)-derived parameters to the indices of left ventricular (LV) pressure-volume (PV) analysis to detect cardiac dysfunction in rat models of type-1 (T1DM) and type-2 (T2DM) diabetes mellitus. METHODS...

The iron-57 Mössbauer spectra of the linear, two-coordinate complexes, [K(crypt-222)][Fe(C(SiMe3)3)2], 1, and Fe(C(SiMe3)3)2, 2, were measured between 5 and 295 K under zero applied direct current (dc) field. These spectra were analyzed with a relaxation profile that models the relaxation of the hyperfine field associated with the inversion of the iron cation spin. Because of the lifetime of th...

In this thesis, the multiple-relaxation-time model of the collision operator in the lattice Boltzmann method is presented. In contrast to the simple Bhatnagar-GrossKrook approximation, not only a single but various relaxation parameters are available and can be used to optimise the simulation results. The main idea behind this approach is the construction of a space based on the moments of the ...

PURPOSE To evaluate quantitative T1 and T2 relaxation times and magnetization transfer ratios (MTRs) in the early diagnosis of patellar cartilage osteoarthritis (OA) and to quantify and possibly refine the current Kellgren-Lawrence score criteria. MATERIALS AND METHODS A total of 92 cases of knee joints with 40 normal volunteers and 30 patients with OA were prospectively evaluated. The knee j...

We report the effects of peptide binding on the (15)N relaxation rates and chemical shifts of the C-SH3 of Sem-5. (15)N spin-lattice relaxation time (T(1)), spin-spin relaxation time (T(2)), and ((1)H)-(15)N NOE were obtained from heteronuclear 2D NMR experiments. These parameters were then analyzed using the Lipari-Szabo model free formalism to obtain parameters that describe the internal moti...

This study uses the analysis of 13C nuclear magnetic resonance (NMR) spectra and NMR relaxation parameters to study the structure and functional group distribution of a fulvic acid and a humic acid. The spectra and relaxation parameters are obtained with a new cross polarization magic angle spinning (CP-MAS) 13C NMR technique that gives qualitatively and quantitatively accurate results at highe...

Thermal conductivity in dielectric crystals is the result of the relaxation of lattice vibrations described by the phonon Boltzmann transport equation. Remarkably, an exact microscopic definition of the heat carriers and their relaxation times is still missing: Phonons, typically regarded as the relevant excitations for thermal transport, cannot be identified as the heat carriers when most scat...

Cardiac magnetic resonance imaging (CMR) is well established and considered the gold standard for assessing myocardial volumes and function, and for quantifying myocardial fibrosis in both ischemic and nonischemic heart disease. Recent developments in CMR imaging techniques are enabling clinically-feasible rapid parametric mapping of myocardial perfusion and magnetic relaxation properties (T1, ...
