OBJECTIVES The long elimination half-life of teicoplanin facilitates outpatient parenteral antibiotic therapy (OPAT) with thrice-weekly dosing. This study aimed to develop teicoplanin dosage guidelines for OPAT use from routine clinical data. METHODS Patients received 15-25 mg/kg/day for 3 days, then 15-25 mg/kg thrice weekly. Trough concentrations were measured weekly and doses adjusted to m...

three experiments were conducted in tissue culture and biotechnology laboratory of horticulture department of mohaghegh ardabili university in 2012. for the regeneration of plant from seed, different concentrations of naoh (5, 10, 15, 20 m) and various scarification methods with sandpaper (soft scarification, medium scarification and hard scarification) were used based on completely randomized ...

In Parkinson's disease (PD), prolonged exposure to L-3,4-dihydroxyphenylalanine (L-DOPA) results in motor fluctuations, such as the on-off phenomenon, and L-DOPA-induced dyskinesia. Previously, we found that activation of 5-HT(1A) in the substantia nigra pars compacta (SNc) decreased catalepsy in parkinsonian rats. In the current investigation, we attempted to evaluate the effect of buspirone o...

Omeprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the H /K ATPase enzyme system at the secretory surface of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the gastric mucosa, omeprazole has been characterized as a gastric acid-pump inhibitor,...

Abstract The water reservoirs are getting polluted due to increasing amounts of micropollutants such as pharmaceuticals, organic polymers and suspended solids. Powdered activated carbon (PAC) has been proved be a promising solution for the purification without having harmful impacts on environment. Parameters PAC dosing, wastewater hardness, effect coagulant flocculant were evaluated in batch s...

PURPOSE Long term L-DOPA therapy in Parkinson's disease is associated with troublesome motor fluctuations such as L -DOPA Induced dyskinesia and wearing off effect. Our recent study showed that activation of 5-HT1A receptors could improve the anti-cataleptic effect of L-DOPA in parkinsonian rats. In this study we investigated the effect of fluoxetine on anti-parkinsonian effect of L-DOPA in 6-h...

Introduction: Humic acids have adverse effects on the water quality, then should be removed from water resources. The aim of this study was to evaluate the effect of nitrate as a radical scavenger for removal of humic acid from aqueous solutions by electron beam irradiation. Materials and Methods: In this study, after preparation of stock humic acid solution in alkaline condition, different con...

The abscission of Alstroemeria petals is the serious problem at the industry of cut flowers of this plant. In this study, cut Alstroemeria cv. Bridal flowers were pulsed with solutions containing natural essential oil carvacrol, gibberellic acid and benzyladenine (50 and 100 mg L-1), -5-sulfosalicylic acid (1 and 1.5 mM) and sucrose (5 and 10%) for 24 hours. The distilled water was used as cont...
