Ginger root (Zingiber officinale) is an herbal supplement used to control severe nausea and vomiting during pregnancy. It is also prepared as a tincture to revitalize the uterus during labor. The purpose of this study was to determine if revitalizing the uterus involved changes in uterine contractile activity. Volumes of ginger root juice (20-1000 μL) were applied directly to isolated mouse ute...

introduction: the aim of this in vitro study was to compare the efficacy of protaper retreatment (protaper r) and mtwo retreatment (mtwo r) files in removing gutta-percha and guttaflow from endodontically treated straight root canals. methods and materials: the root canals of 60 human mandibular single-rooted premolars were prepared and randomly divided into two groups ( n =30). in groups a and...

BACKGROUND Though retrograde neuronal death and vascular insufficiency have been well established in plegics following intracerebral hemorrhage, the effects of plegia on arterial nervorums of peripheral nerves have not been reported. In this study, the histopathological effects of the intracerebral hemorrhage on the dorsal root ganglions and sciatic nerves via affecting the arterial nervorums w...

introduction : to evaluate the efficacy of niti mechanical rotary instrumentation and hedstrom file for gutta-percha/sealer removal computed tomography (ct) was utilized in vitro . materials and methods: thirty extracted human single rooted teeth, each with a single canal were selected. the samples were decoronated with a double faced diamond disk to have 17-mm root; teeth roots were instrument...

-Despite evidence of its economic impact, very little is known about transplant shock. This study was designed to evaluate transplant shock in relation to root volume and soil water content for two year-old Douglas-fir seedlings. Preliminary results found that new growth decreased and days to budbreak increased with higher moisture stress. This effect was most pronounced for high root volume se...

OBJECTIVE To quantify the amount of tooth movement and orthodontically induced root resorption (OIRR) in ovariectomized rats. MATERIALS AND METHODS Five 10-week-old female Wistar rats undergoing ovariectomy (OVX) were investigated as the experimental group, and the other five without ovariectomy served as the control group. Four weeks after ovariectomy, 25-g nickel-titanium closed-coil spring...

Podocarps are often found on lownutrient soils and further exacerbate nutrient limitation through the production of recalcitrant litter. Understanding podocarp ecology therefore depends on understanding the root adaptations of podocarps to obtain nutrients. The roots of podocarps are heterorhizic (having two root forms) with abundant spherical determinate short roots, a unique form of largely u...

1 An increasing number of studies have shown that plants produce more root mass when sharing rooting space with an intraspecific neighbour as compared with plants growing alone. This so-called self/non-self discrimination has been suggested as a mechanism by which plants may prevent wasteful competition with their own roots and enhance their competitive ability for nutrients with roots of neigh...
