Aim/purpose – The study was based on social exchange theory and addressed the effects of firm-based organizational citizenship behavior (OCB) normative con- tinuance commitment (OC). Multigroup behavioral differences among pharmaceutical executives were also evaluated. Design/methodology/approach This employed an empirical, explanatory cross- -sectional with online questionnaires administered t...

Long-chain alkenones (LCAs) produced by phylogenetically classified Groups 1 and 3 Isochrysidales are increasingly used for paleotemperature and/or paleosalinity reconstructions in oligohaline lakes marine environments. However, there considerable difficulties the paleoenvironmental interpretation of LCAs from Group 2 thriving saline lakes. The biggest challenge lies our poor understanding comp...

Small, secreted proteins have been found to play crucial roles in interactions between biotrophic/hemi-biotrophic pathogens and plants. However, little is known about the roles of these proteins produced by broad host-range necrotrophic phytopathogens during infection. Here, we report that a cysteine-rich, small protein SsSSVP1 in the necrotrophic phytopathogen Sclerotinia sclerotiorum was expe...

BACKGROUND & OBJECTIVE Placental abruption, an ischemic placental disorder, complicates about 1 in 100 pregnancies, and is an important cause of maternal and perinatal morbidity and mortality worldwide. Metabolomics holds promise for improving the phenotyping, prediction and understanding of pathophysiologic mechanisms of complex clinical disorders including abruption. We sought to evaluate mat...

Proliferation and hypoxia affect the efficacy of radiotherapy, but radiation by itself also affects the tumor microenvironment. The purpose of this study was to analyze temporal and spatial changes in hypoxia, proliferation and apoptosis after irradiation (20 Gy) in cells of a murine adenocarcinoma tumor line (C38). The hypoxia marker pimonidazole was injected 1 h before irradiation to label ce...

BACKGROUND Recently, a new PtCl2-histamine complex, and its radioactive analogues labelled with I-131 and I-125 have been synthesised and investigated both in vitro and in vivo. In this preliminary report the survival rate of radioactive platinum-[125I] histamine therapy in tumour-bearing mice is demonstrated. MATERIAL AND METHODS A murine model of transplantable colon adenocarcinoma (C38) in...
