STUDY OBJECTIVES To test the hypothesis that the presence of sensitization to indoor allergens is associated with increased severity of airway obstruction in elderly subjects with asthma. DESIGN Cohort study of subjects enrolled in a public hospital asthma clinic. SETTING Asthma clinic in a municipal public hospital serving an indigent population in New York City. PATIENTS Subjects aged >...

Background: Environmental contamination by chromium (Cr) has become an important issue due to its adverse effects on human health and environment. This study was done to evaluate the application of modified bentonite using sulfuric acid as an adsorbent in the removal of hexavalent Cr from aqueous solution. Methods: Adsorbent features were determined using x-ray diffraction (XRD), fourier transf...

caspian sea as the biggest surrounded water body in the word has long been in the pressure from environmental standpoints due to the fact that its large is surrounding by the larg domestic, industrial and agricultural areas. concern to inverse impacts of the inputted pollutants on the aquatic organism and margin human societies’ health, quality monitoring of the sediment as the main fate of the...

background: the nonamnesic type of mild cognitive impairment (na?mci) is predementia state with subtle decline incognitive domains except memory. although cognitive rehabilitation (cr) has been investigated in amnesic type of mci, we could not find any trial that rehabilitated na?mci exclusively. we studied the effectiveness of cr on na?mci. materials and methods: this study was a blinded, rand...

BACKGROUND In a recent study, we showed that administration of low-dose creatine (Cr) (60 mg/kg daily) improved work capacity in patients with McArdle disease. OBJECTIVE To assess the efficacy of high-dose Cr therapy in McArdle disease. DESIGN Randomized, double-blind, placebo-controlled crossover study. PATIENTS Nineteen patients with McArdle disease. INTERVENTION Treatment with Cr, 15...

hepatic and renal contents of essential trace elements provide good clues to monitor the nutritional status of grazing animals. liver and kidney samples were collected from 60 sheep and 60 goats slaughtered in zarrinshahr abattoirs and analyzed for essential trace elements. hepatic fe concentrations were significantly higher in sheep than goats. there were also higher renal and hepatic fe conce...

Tradescantia pallida (Wandering jew)-a succulent perennial herb-was screened to be a potent chromium (Cr) accumulator. Its ability to grow under Cr stress was examined by studying biochemical changes and physiological response of the plant in presence of 5-20 mg L(-1) Cr(VI) concentration in hydroponic environment for up to ca. 90 days. Average Cr(VI) bioaccumulation in plant roots reached abou...

Introduction: Although proximal dental caries are very common, clinical examinations cannot detect them all. Panoramic radiography has been widely used in dentistry for both diagnosis and screening. This study aimed to investigate and compare the efficacy of two digital panoramic radiography techniques in the diagnosis of proximal caries. Methods: A total number of 60 patients referred to a den...
