combination dosage forms of naproxen sodium and pseudoephedrine hydrochloride are used for symptomatic treatment of cold and sinus disorders. in this study, fourth-order derivative spectrophotometric method was used for simultaneous determination of naproxen sodium and pseudoephedrine hydrochloride. the method was linear over the range of 2-28 μg/ml for pseudoephedrine hydrochloride and 4-200 μ...

Purpose: To investigate the effects of sodium bicarbonate (NaHCO3) on exhaustive activity and physiological parameters of fatigue in conscripts. Materials and Methods: Thirty conscripts did Wingate test in two groups: sodium bicarbonate group (treatment) and placebo (control) group. In both groups, sodium bicarbonate (0.3 g/kg of body mass) or placebo was ingested 60 minutes before the t...

this research was conducted to determine the best temperature for storing different melon cultivars (ghasry, khaghany, tashkandy) and the best concentration and treatment length for immersion in an emulsion of sunflower oil and sodium bicarbonate. after harvest, precooling and sorting, the melons were treated with an emulsion of sunflower oil (3%, 5%) and sodium 2% sodium bicarbonate for 5 or 1...

migraine is a common and incapacitating neurologic disorder manifesting with episodic moderate to a severe headache and other symptoms such as photophobia, phonophobia, nausea, and vomiting. triptans and ergot compounds have been used as treatment options for an acute migraine headache for many years. triptans are considered the first line of treatment in patients with moderate to a severe migr...

The optimal dialysate sodium concentration for chronic hemodialysis patients remains controversial. Conflicting data from small observational studies and large cohort study have not convinced nephrologists to choose either a high or low dialysate. Despite lack of evidence, I would prescribe individualized concentrations with risk hypertension volume overload, aligning the patients’ predialysis ...

Background: Arsenic as a heavy metal exerts malformation and changes in the reproductive system of men via induction of oxidative stress. We sought to investigate the impact of Vitamin C (Vit C), as a potent antioxidant, on sperm quality and testicular tissue in mice that received sodium arsenite. Methods and materials: NMRI mice were classified into four groups: control, sodium arsenite (7 mg...

Multiple sclerosis: needs for biomarkers of neuronal injury Multiple sclerosis (MS) is a chronic disease of the CNS, representing the leading cause of neuro­ logical disability in young adults. Focal inflam­ matory and demyelinating lesions disseminated in the cerebral white matter have been considered for several decades to be the main feature of MS. However, recent histological studies have a...
