Understanding cross-cultural aspects of emotional overinvolvement (EOI) on psychosis outcomes is important for ensuring cultural appropriateness of family interventions. This systematic review explores whether EOI has similar impact in different cultural groups and whether the same norms can be used to measure EOI across cultures. Thirty-four studies were found that have investigated the impact of EOI on outcomes across cultures or culturally adapted EOI measures. The relationship between high EOI and poor outcome is inconsistent across cultures. Attempts to improve predictive ability by post hoc adjustment of EOI norms have had varied success. Few studies have attempted a priori adaptations or development of culture-specific norms. Methodological differences such as use of different expressed emotions (EE) measures and varying definitions of relapse across studies may explain a lack of EOI outcome relationship across cultures. However, our findings suggest that the construct and measurement of EOI itself are culture-specific. EOI may not necessarily be detrimental in all cultures. The effect of high EOI may be moderated by the unexplored dimension of warmth and high levels of mutual interdependence in kin relationships. Researchers should reevaluate the prevailing concepts of the impact of family relations on the course and outcome of psychotic disorders, specifically focusing on the protective aspects of family involvement. Clinically, family interventions based on EE reduction should take cultural differences into account when treating families from different ethnocultural groups. © 2013 The Author.

The nonlinear propagation of ion solitary pulses in a warm collisionless electron-positron-ion plasma with ultrarelativistic degenerate electrons and positrons has been investigated. Arbitrary and small- (but finite-) amplitude ion solitary pulses are investigated by deriving the Korteweg-de Vries equation and an energy-balance-like expression involving a Sagdeev-like pseudopotential. The existence regions for ion solitary pulses have been precisely defined and numerically investigated. The ion solitary pulse profiles are also displayed. Applications to the interior of white dwarf stars and the corona of magnetars are discussed. © 2012. The American Astronomical Society. All rights reserved.

ATM is the most significant molecule involved in monitoring the genomic integrity of the cell. Any damage done to DNA relentlessly challenges the cellular machinery involved in recognition, processing and repair of these insults. ATM kinase is activated early to detect and signal lesions in DNA, arrest the cell cycle, establish DNA repair signaling and faithfully restore the damaged chromatin. ATM activation plays an important role as a barrier to tumorigenesis, metabolic syndrome and neurodegeneration. Therefore, studies of ATM-dependent DNA damage signaling pathways hold promise for treatment of a variety of debilitating diseases through the development of new therapeutics capable of modulating cellular responses to stress. In this review, we have tried to untangle the complex web of ATM signaling pathways with the purpose of pinpointing multiple roles of ATM underlying the complex phenotypes observed in AT patients. © 2011.

Copper oxide nanoparticles produced in double distilled water at room temperature by laser ablation of the Cu target have been investigated using TEM, SEM, AFM, X-ray diffraction, photo-spectrometry and PIXE. Q-switched Nd:YAG laser operating at 1064 nm with a pulse duration of 5-6 ns was used to conduct the experiments in the fluence range of 5.73-9.87 J/cm2. In each experiment, 12,000 laser pulses were used to ablate the target placed in double distilled water. Different diagnostic techniques reveal that the nanoparticles have a size between 2-55 nm and their mean size as well as the width of particle distribution increases with the laser fluence. Since no surface active material (surfactant) was added to water, the nanoparticles aggregated and settled down at the bottom of the container within a week. In addition to stable Cu 2O, the XRD spectrum also shows the presence of suboxide Cu 64O in the colloidal solution of nanoparticles produced in the present study. © 2012 Springer-Verlag Berlin Heidelberg.

In late nineteen eighties, the Neutron Diffraction Commission of International Union of Crystallography initiated a project to compile the most accurate values of the Debye-Waller thermal parameter B of cubic elements as well as of cubic binary compounds. N. M. Butt and co-workers recommended such values for 22 cubic elements (Butt et el 1988) and 52 cubic binary compounds (Butt et al., 1993) determined at room temperature by diffraction methods using x-rays, neutrons, γ - rays, and high voltage electrons. Since then, several attempts have been made to correlate numerous general, thermal, metallurgical, mechanical, and crystal defect properties of cubic structure crystals with their room-temperature Debye-Waller thermal parameter B not only in solid, liquid and vapor phases but also in plasma state. The correlations between microscopic parameter B and macroscopic or bulk properties of crystals have been found to be systematic. This connection between micro and macro aspects of materials has set new trends in the interpretation of the behavior of crystalline materials. © 2015 Elsevier Ltd.

Using kinetic theory for homogeneous collisionless magnetized plasmas, we present an extended review of the plasma waves and instabilities and discuss the anisotropic response of generalized relativistic dielectric tensor and Onsager symmetry properties for arbitrary distribution functions. In general, we observe that for such plasmas only those modes whose magnetic-field perturbations are perpendicular to the ambient magnetic field, i. e., B1 ⊥ B0, are effected by the anisotropy. However, in oblique propagation all modes do show such anisotropic effects. Considering the non-relativistic bi-Maxwellian distribution and studying the relevant components of the general dielectric tensor under appropriate conditions, we derive the dispersion relations for various modes and instabilities. We show that only the electromagnetic R- and L- waves, those derived from them (i. e., the whistler mode, pure Alfvén mode, firehose instability, and whistler instability), and the O-mode are affected by thermal anisotropies, since they satisfy the required condition B1 ⊥ B0. By contrast, the perpendicularly propagating X-mode and the modes derived from it (the pure transverse X-mode and Bernstein mode) show no such effect. In general, we note that the thermal anisotropy modifies the parallel propagating modes via the parallel acoustic effect, while it modifies the perpendicular propagating modes via the Larmor-radius effect. In oblique propagation for kinetic Alfvén waves, the thermal anisotropy affects the kinetic regime more than it affects the inertial regime. The generalized fast mode exhibits two distinct acoustic effects, one in the direction parallel to the ambient magnetic field and the other in the direction perpendicular to it. In the fast-mode instability, the magneto-sonic wave causes suppression of the firehose instability. We discuss all these propagation characteristics and present graphic illustrations. The threshold conditions for different instabilities are also obtained. © 2012 Sociedade Brasileira de Física.

PDGF is a growth factor and is extensively involved in multi-dimensional cellular dynamics. It switches on a plethora of molecules other than its classical pathway. It is engaged in various transitions of development; however, if the unleashed potentials lead astray, it brings forth tumourigenesis. Conventionally, it has been assumed that the components of this signalling pathway show fidelity and act with a high degree of autonomy. However, as illustrated by the PDGF signal transduction, reinterpretation of recent data suggests that machinery is often shared between multiple pathways, and other components crosstalk to each other through multiple mechanisms. It is important to note that metastatic cascade is an intricate process that we have only begun to understand in recent years. Many of the early steps of this PDGF cascade are not readily targetable in the clinic. In this review, we will unravel the paradoxes with reference to mitrons and cellular plasticity and discuss how disruption of signalling cascade triggers cellular proliferation phase transition and metastasis. We will also focus on the therapeutic interventions to counteract resultant molecular disorders.

Stress and lattice constants are significant factors considered in evaluating the deformation mode of crystalline materials. Zinc oxide (ZnO) nanostructured thin films were prepared via the process of wet oxidation of Zn at temperatures varying from 420 to 570 °C. Structural, elemental and optical characterizations were carried out using various techniques, to investigate the properties of the samples. Scanning electron microscopy (SEM) images showed improvement in the ZnO structure and the grain size of the ZnO became larger as the oxidation temperature was increased, while maintaining a constant flow rate of wet oxygen. X-ray diffraction (XRD) patterns also showed that ZnO films suffered from compressive stress due to elongation in the lattice constant. With increase in the oxidation temperature, the compressive stress became tensile stress because of the decrease in the lattice constants. Photoluminescence (PL) spectra revealed the influence of stress on the energy band gap, with wet oxidation further giving rise to the transition of stress from compressive to tensile. © 2012 Published by Elsevier B.V.

The Vlasov kinetic equation is solved using gyrokinetic theory and the dielectric tensor for non-relativistic, magnetized, bi-Maxwellian plasmas is calculated. A generalized dispersion relation for kinetic Alfven waves is derived taking into account the density inhomogeneity and temperature anisotropy. The modified dispersion relation thus obtained is then used to examine the propagation characteristics of the kinetic Alfven waves in the inertial regime. The importance of density inhomogeneity and temperature anisotropy for Solar corona is highlighted. The growth rate of the inertial Alfven wave proves that density inhomogeneity acts as a source of free energy. © 2013 Elsevier B.V.
