The relative energies of side-on versus end-on binding of molecular oxygen to a supported Cu(I) species, and the singlet versus triplet nature of the ground electronic state, are sensitive to the nature of the supporting ligands and, in particular, depend upon their geometric arrangement relative to the O2 binding site. Highly correlated ab initio and density functional theory electronic struct...

Systemic drugs have been used widely in the treatment of many skin diseases. Although dermatologists are familiar with the guidelines of selecting appropriate patients and prescribing systemic drugs, their knowledge about the side effects and significant interactions of systemic drugs used in dermatology is more limited. So a short review on important drug interactions seems to be useful. Some ...

in the crystal structure of the title polymeric compound, [c42h38n6o33sr5.2(h2o)]n, five independent metal atoms (sr1-sr5) have different coordination environments. the sr1 and sr5 atoms are nine coordinated and feature distorted tricapped trigonal-prismatic and capped square-antiprismatic geometries, respectively. the rest srii atoms have eight coordination numbers. these units are connected v...

Abstract One of the main concerns in educational settings has been the degree of the learners’ involvement in learning and the extent to which they actively participate in classroom talks and interactions. The present study is an emic-based ethnographic study aimed at providing insights about patterns of talk and different degrees of interaction in EFL university classes with a specific focus o...

prescriptions written by general practitioners and medical specialists were studied and compared to determine the type, time of onset and clinical importance of drug-drug interactions (ddis) in an attempt to reduce further complications. in 2007, 28, 956, 638 prescriptions and 15, 610, 912 prescriptions in 2008 were filled by pharmacies affiliated with medical science universities. these prescr...

Since their introduction by E. L. Eliel nearly four decades ago, derivatives of 1,3-dioxane have proved useful in conformational analysis. Examples are discussed, where 5-polar substituents permit the evaluation of fundamental phenomena such as attractive and repulsive gauche effects, electrostatic interactions, and stereoelectronic effects. By the same token, 2-substituted 1,3-dioxanes, 1,3-di...

during early neurogenesis, the floor plate plays an essential role(s) in the differentiation of the ventral portion of neural tube. in this study, we detected the specific distribution of unique glycoconjugate during the floor plate differentiation. formalin fixed paraffin sections of balb/c mice (10-14 embryonic days) were processed for histochemical studies using horseradish peroxidase-labell...
