introduction: the most common manifestation of disturbed neurological function following stroke is motor weakness. muscle weakness has been implicated as a factor underlying deficits in gait performance in subjects who have suffered strokes . the purpose of this study was to investigate the relationship between involved lower extremity isometric muscle strength and two functional tasks: gait ab...

Cadmium telluride quantum dots (CdTe QDs) are used as near-infrared probes in biologic and medical applications, but their cytological effects and mechanism of potential toxicity are still unclear. In this study, we evaluated the toxicity of CdTe QDs of different sizes and investigated their mechanism of toxicity in the yeast Saccharomyces cerevisiae. A growth inhibition assay revealed that ora...

Increasing global notices in environmental protection, green supply chain management (GSCM) has received much attention by researchers and managers more than the past. Commonly, firms have considered cost criteria to select their suppliers. Despite the fact that there are various papers considering the formal criteria in supplier selection, there is a few limited numbers considering the environ...

Results Preliminary results show that regular outdoor activities and exercise are positively correlated with people’s mental and physical health status, and dog walking has been shown as a viable method for physical activity. The concept of green infrastructure stresses the need for well-connected, easyaccessible, multifunctional green networks. The quality of urban green infrastructure and the...

objectives: a reduction in bond strength of composite to bleached enamel has been reported immediately after bleaching treatment. application of some antioxidant agents may decrease the adverse effects of whitening agents on bond strength and enhance composite bond to enamel. this study aimed to assess the effect of green tea, sodium ascorbate, sage and grape seed extract on bond strength of co...
