Objectives The objective of this study was to evaluate the ability of the stroke volume (SV) variation with 250 ml (Δ250SV) of volume expansion (VE) to predict further SV increase with VE. We also studied the ability of respiratory SV variation (ΔrespSV) to discriminate fluid responisvenness according to the amount of VE (250 then 500 ml). Fluid expansion consisted on infusion of 500 ml of Ring...
ABSTRACT- A pot experiment was conducted to elucidate the effects of single and co-inoculation of maize plant with Bacillus mycoides and Micrococcus roseus, indigenous to HMs contaminated soils, on the plant growth and uptake of essential nutrients and Ni by maize in the soil polluted by 250 and 500 mg Ni kg-1. At each level of Ni contamination, shoot dry weight and nutrients uptake significant...
BACKGROUND This double-blind, multicenter, placebo-controlled study determined the efficacy and safety of dofetilide in converting atrial fibrillation (AF) or atrial flutter (AFl) to sinus rhythm (SR) and maintaining SR for 1 year. METHODS AND RESULTS Patients with AF or AFl (n=325) were randomized to 125, 250, or 500 microgram dofetilide or placebo twice daily. Dosages were adjusted for QTc ...
the current study dealt with the interaction of garlic homogenate (gh) with propranolol (pro) in rat, and to determine whether this effect is associated with biochemical and histological changes. albino rats were treated with gh at three different doses of 125 mg/kg (gh-125), 250 mg/kg (gh-250) and 500 mg/kg (gh-500) orally for 30 days and pro was incorporated in the interactive groups during t...
Plant growth in a controlled environment system is highly dependent on the availability of light. The light-emitting diode (LED) capable providing needed quality and quantity light for plant. purpose this study was to determine effect white LED intensity vitro propagated apple (M-9) seedlings system. Seedlings were grown 30 days under five different intensities: 100–500 (L1), 250–500 (L2), 500–...
This study investigated if the use of the pesticides cyprodinil and fludioxonil produced an inhibitory effect on the bovine liver catalase (CAT) activity. It was documented that the activity of the enzyme decreased with increasing concentrations of cyprodinil and fludioxonil from 0 to 500 ppm. At pesticide concentrations of 250 and 500 ppm, the activity of CAT remained unchanged and passed to a...
The international CONFIRM study showed that fulvestrant 500 mg improved progression-free survival (PFS) vs fulvestrant 250 mg in postmenopausal women with estrogen receptor (ER)-positive locally advanced/metastatic breast cancer (LA/MBC). In this randomized, double-blind study, postmenopausal Chinese women with ER-positive LA/MBC and progression after endocrine therapy received fulvestrant 500 ...
