BACKGROUND The function of endothelial progenitor cells (EPCs), which are key cells in vascular repair, is impaired in diabetes mellitus. Nitric oxide (NO) and reactive oxygen species can regulate EPC functions. EPCs tolerate oxidative stress by upregulating superoxide dismutase (SOD), the enzyme that neutralizes superoxide anion (O2-). Therefore, we investigated the roles of NO and SOD in gluc...

The dominant allergenic components of grass pollen are known by immunologists as group 1 allergens. These constitute a set of closely related proteins from the beta-expansin family and have been shown to have cell wall-loosening activity. Group 1 allergens may facilitate the penetration of pollen tubes through the grass stigma and style. In maize (Zea mays), group 1 allergens are divided into t...

abstract turf grass as a main grown cover plant has a unique place in green space planning. in order to study the effect of hydrogel and paclobutrazol on water requirement of turfgrasse (lolium perenne l. barbal) a factorial experiment based on a brcd with 3 replication was conducted in the summer of 2010 in mashhad. the factors under study were 4 levels of hydrogel (0, 3, 6, 9 gr/kg soil), 3 l...

BACKGROUND Numerous injuries have been attributed to playing on artificial turf. Recently, FieldTurf was developed to duplicate the playing characteristics of natural grass. No long-term study has been conducted comparing game-related, high school football injuries between the 2 playing surfaces. HYPOTHESIS High school athletes would not experience any difference in the incidence, causes, and...

BACKGROUND Calcium antagonists normalize endothelial dysfunction in many cardiovascular diseases. There is no known receptor, however, for calcium antagonists in endothelial cells (ECs). We hypothesized that vascular smooth muscle cells (VSMCs) are involved in the mechanism underlying the normalization of endothelial dysfunction by calcium antagonists. METHODS AND RESULTS Coculture studies wi...
