The effect of Ca on the absorption and translocation of Mn, Zn and Cd in excised barley roots was studied using a multi-compartment transport box technique. A radioisotope (54Mn,65Zn or115mCd)-labelled test solution was supplied to the apexes of excised roots and the distribution pattern in the roots was examined in the absence or presence of Ca.

Fas (Apo-1/CD95) ligand, which is a type II membrane protein, is a major inducer of apoptosis. Osthole is a coumarin derivative present in medicinal plants. The effect of osthole on hepatitis induced by anti-Fas antibody in mice was studied. Pretreatment of mice with osthole (10, 50, and 100 mg/kg, i.p.) prevented the elevation of plasma alanine(More)
Vitamin E (VE) blended ultra-high molecular weight polyethylene (UHMWPE) has been developed in Japan as a material for use in total knee replacement (TKR). Various results have demonstrated that VE blended UHMWPE reduces the incidence of delamination failure and lowers the amount of wear produced during knee simulator testing. It was also found that wear(More)
To provide a better understanding of plant responses to salt and water stresses, the effects of high concentrations of sodium chloride (NaCl) and polyethylene glycol (PEG) on the growth and ion absorption in plants were examined at similar osmotic potential conditions, using the water culture method. The inhibitory effect on plant growth appeared to be only(More)
A simple view control mechanism is developed and applied to a virtual learning environment for the refraction of light. The view control function is linked to body movement. A learner's observing position and direction are concurrently chased and then the visual information of an observed object is displayed on a head mounted display. The behavior of light(More)
