The purpose of this factorial study was to establish normative data for the Italian version of the Communication Attitude Test (CAT) in order to determine whether or not the speech-associated attitude reported by Italian children who stutter (CWS) differs significantly from that of their nonstuttering peers (CWNS). Toward this end, the Italian CAT was administered to 149 CWS and 148 CWNS betwee...

influence of aluminum, gallium, indium- doping on the boron-nitride nanotubes (bnnts) investigated with density functional theory (dft) and hartreefock (hf) methods. for this purpose, the chemical shift of difference atomic nucleus was studied using the gauge included atomic orbital (giao) approch. in the following, structural parameter values, electrostatic potential, thermodynamic parameters,...

one of the methods to enhance bio-accessibility of drugs like acridone and its oxime is toform inclusion complexes with β-cyclodextrin. the formation of such complexes has beenconfirmed by changes in spectral characteristics and melting point data. the aqueous phasesolubility studies reveal 1:1 stoichiometry between the compound and, β-cyclodextrin. the studyof thermodynamic parameters like δg,...

When amorphous materials are compressed their structures are expected to change in response to densification. In some cases, the changes in amorphous structure can be discontinuous and they can even have the character of first-order phase transitions. This is a phenomenon referred to as polyamorphism. Most evidence for polyamorphic transitions between low and high density liquids or analogous t...

The development of HIV-1 protease inhibitors has been the historic paradigm of rational structure-based drug design, where structural and thermodynamic analyses have assisted in the discovery of novel inhibitors. While the total enthalpy and entropy change upon binding determine the affinity, often the thermodynamics are considered in terms of inhibitor properties only. In the current study, pr...

We study self-organization of collective motion as a thermodynamic phenomenon in the context of the first law of thermodynamics. It is expected that the coherent ordered motion typically self-organises in the presence of changes in the (generalized) internal energy and of (generalized) work done on, or extracted from, the system. We aim to explicitly quantify changes in these two quantities in ...

In this review, changes in aggregation induced by thermodynamic parameters, namely concentration and temperature are discussed. Most of these changes are concerned with sphere-to-rod transitions. On the other hand, the use of an external trigger such as light can induce large aggregation changes in photosurfactant systems. This is discussed in the second part of this review and several examples...

Cytosine DNA methylation (CDM) is a stable epigenetic modification to the genome and a widespread regulatory process in living organisms that involves multicomponent molecular machines. Genome-wide cytosine methylation patterning participates in the epigenetic reprogramming of a cell, suggesting that the biological information contained within methylation positions may be amenable to decoding. ...

Changes in the respiratory state of rat liver mitochondria caused significant changes (up to 10-fold) in the rates of oxidative deamination of tyramine, indicating interactions between the inner coupling membrane and the monoamine oxidase sites in the outer membrane, and suggesting the possibility that monoamine oxidase is regulated by the thermodynamic state of the mitochondria.

We have analyzed the effects of different native membrane lipid composition on the thermodynamic properties of the Na+-K+-ATPase in different epithelia from the gilthead seabream Sparus aurata. Thermodynamic parameters of activation for the Na+-K+-ATPase, as well as contents of lipid classes and fatty acids from polar lipids were determined for gill epithelia and enterocytes isolated from pylor...
