Reactive oxygen species (ROS) have been indicated in the development of diseases such as cancer, cardiovascular diseases, degenerative diseases and ageing. An increasing body of evidence indicates an association between increased and persistent oxidative stress and the development of radiation damage in tissues such as skin, central nervous system and kidney. On the basis of the new hypothesis ...

The quality assessment of multimodal conversational interactions is determined by many influence parameters. Stress and cognitive load are two of them. In order to assess the impact of stress and cognitive load on the perceived conversational quality it is essential to control their levels during the interaction. Therefore we present in this paper preliminary experiments carried out to determin...

in this study, the effect of cognitive load (cl) training on duration and accuracy of bimanual coordination (bc) task was investigated. for this purpose, athletic male students of shiraz university were randomly divided into 4 groups: g1 with low cl, g2 with intermediate cl, g3 with high cl and g4 control. the subjects practiced for 6 weeks, 3 sessions a week, 6 blocks, 12 trials. the subjects ...

the present study was undertaken to investigate the beneficial effects of widely-prescribed lipid lowering drugs, pitavastatin, atorvastatin and simvastatin 3-hydroxy-3-methylglutaryl-coenzyme-a (hmg-coa) reductase inhibitors in cognitive dysfunctions of mice. intra-cerebroventricular (icv)-streptozocin-(stz)- and high-fat diet (hfd)-induced amnesia served as interoceptive memory models where a...

Auditory change detection has been studied extensively with mismatch negativity (MMN), an event-related potential. Because it is unresolved if the duration MMN depends on sound pressure level (SPL), we studied effects of different SPLs (56, 66, and 76dB) on the duration MMN. Further, previous research suggests that the MMN is reduced by a concurrent visual task. Because a recent behavioral stud...

Multiple attribute search is a central feature of economic life: we consider much more than price when purchasing a home, and more than wage when choosing a job. An experiment is conducted in order to explore the effects of cognitive limitations on choice in these rich settings, in accordance with the predictions of a new model of search memory load. In each task, subjects are made to search th...

PTH and mechanical loading might act synergistically on bone formation. We tested the in vivo effect of the L-type voltage-sensitive calcium channel (VSCC) blocker, verapamil, on bone formation induced by human PTH-(1-34) (PTH) injection with or without mechanical loading. Adult rats were divided into eight groups: vehicle, verapamil, PTH, or verapamil plus PTH with or without mechanical loadin...
