On growth of spinodal instabilities in nuclear matter-II:asymmetric matter

As an extension of our previous work, the growth of density fluctuations in the spinodal region of charge asymmetric nuclear matter is investigated in the basis of the stochastic mean-field approach in the non-relativistic framework. A complete treatment of density correlation functions are presented by including collective modes and non-collective modes as well.Comment: 20 pages, 6 figures, Accepted by Physical Review

Spinal cord stimulation in failed back surgery

Objective: Spinal cord stimulation is used for treating failed back surgery syndrome, chronic arachnoiditis, peripheral neuropathies, postamputation phantom pain, complex regional pain syndrome and pain secondary to spinal cord injury. In this study we present 7 cases with intractable neuropathic radicular pain which developed following spine surgery. Material and Methods: Spinal cord stimulation was applied to 7 (3male/4 female) patients who had failed back surgery syndrome and pain resistant to medical and invasive methods, with the council decision, which included neurosurgery, neurology, and psychiatry. One week stimulation trial was applied to all cases. Results:The mean age of the patients was 54.85±7.64 years. The mean of pain intensity in Visual Analog Scale was 8.71±0.74 at preoperative status and post operative pain intensity was 2.27±0.67 at 6 months. Pain intensity significantly decreases after spinal cord stimulation (p=0.000). One of the three cases who had unsuccessful trial period received morphine pump implantation, and percutaneous lumbar sympathectomy was applied to another one. One case who received permanent implantation was replaced to another location due to skin erosion. There was no morbidity. Conclusion: Spinal cord stimulation is an effective tool in reducing pain, in patients who have unsuccessful lower back surgery with the correct indications

Insulin Resistance and Left Ventricular Mass in Non-Diabetic Hemodialysis Patients

AbstractBackgroundInsulin resistance (IR) is frequently recognized in patients with uremia, and it is thought that IR has a basic role in the pathogenesis of cardiovascular disease.ObjectiveTo evaluate the effect of IR on cardiovascular risk in non-diabetic patients receiving hemodialysis (HD).MethodsWe performed a cross-sectional observational study that comprised 186 non-diabetic patients receiving HD (95 men; mean [SD] age, 46.4 [10.8] years; age range, 35–60 years) who had been receiving HD for 7.3 (3.5) years. Demographic variables and laboratory values were recorded. Insulin resistance was determined using the Homeostatic Model Assessment (HOMA), and the left ventricular mass index (LVMI) was calculated via echocardiography.ResultsAccording to HOMA-IR levels, patients were categorized as having IR (HOMA-IR score ≥2.5; n = 53) or not having IR (HOMA-IR score <2.5; n = 133). Insulin resistance was determined in 28.4% of study patients. Compared with the non-IR group, the IR group had been receiving HD longer; had greater body mass index; and had higher serum creatinine, uric acid, triglyceride, insulin, and C-reactive protein concentrations, leukocyte count, and LVMI (P < 0.05). Patients with increased LVMI had significantly higher body mass index, systolic blood pressure, serum cholesterol and C-reactive protein concentrations, and HOMA score. At multivariate analysis, systolic blood pressure (β = 0.22; P = 0.03) and HOMA score (β = 0.26; P = 0.01) affected LVMI.ConclusionsInsulin resistance and hypertension are independent risk factors for left ventricular hypertrophy in non-diabetic patients with uremia who are receiving HD. Further studies are needed to indicate the benefits of improving IR for cardiovascular mortality in this subgroup of patients with uremia

Investigations of spinodal dynamics in asymmetric nuclear matter within a stochastic relativistic model

Cataloged from PDF version of article.Early development of spinodal instabilities and density correlation functions in asymmetric nuclear matter are investigated in the stochastic extension of the Walecka-type relativistic mean field including coupling with rho meson. Calculations are performed under typical conditions encountered in heavy-ion collisions and in the crusts of neutron stars. In general, growth of instabilities occur relatively slower for increasing charge asymmetry of matter. At higher densities around rho = 0.4 rho(0) fluctuations grow relatively faster in the quantal description than those found in the semi-classical limit. Typical sizes of early condensation regions extracted from density correlation functions are consistent with those found from dispersion relations of the unstable collective modes

Especificidade nacional-cultural da semântica de unidades fraseológicas, relativas ao campo semântico "ociosidade" nas línguas inglesa e russa

National-cultural specificity of semantics of phraseological units (PU), characterizing the labor activity, in the English and Russian languages, has its special and actual significance in perceiving the depths of national consciousness. This research is devoted to the identification and comparative description of the semantic field of the PU type being investigated and the image-motivational aspects of the PU meaning. The universal and unique traits in the semantics of the PU of both languages are studied, the cultural connotation is defined and described through the cultural interpretation mechanism of all the content components of the studied PU.Cultural connotation, being an interpretation of the components of the PU meaning in the categories of culture, is layered into the connotation as a linguistic concept. Each component of the PU connotation is able to provide additional information of a national cultural character. First of all, such components of the connotation are the emotive and evaluative macrocomponents of the PU semantics.La especificidad nacional-cultural de la semántica de unidades fraseológicas (PU), que caracteriza la actividad laboral, en los idiomas inglés y ruso, tiene su significado especial y real para percibir las profundidades de la conciencia nacional. Esta investigación está dedicada a la identificación y descripción comparativa del campo semántico del tipo de PU que se está investigando y los aspectos de imagen-motivación del significado de la PU. Se estudian los rasgos universales y únicos en la semántica de la PU de ambas lenguas, la connotación cultural se define y describe a través del mecanismo de interpretación cultural de todos los componentes de contenido de la PU estudiada.La connotación cultural, al ser una interpretación de los componentes del significado de la PU en las categorías de la cultura, se superpone a la connotación como un concepto lingüístico. Cada componente de la connotación PU puede proporcionar información adicional de un personaje cultural nacional.
