Constructed wetlands (CWs) have been widely used for wastewater treatment due to advantages such as low cost and easy operation. However, pollutant concentrations directly affect efficiency by inhibiting plant microbial growth. This study aims evaluate the relationship between concentrations, tolerance of plants, horizontal subsurface flow (HSF) CWs receiving synthetic wastewater. The results s...
BACKGROUND Recent advances in perinatal technology have dramatically increased the survival of very low birth weight (VLBW) infants (<1500 g). The possibility that these advances may also prolong the time to death and increase pain and suffering has been of concern, but there have been no population-based evaluations of this issue. METHODS Infant, neonatal, and postneonatal mortality rates an...
The effect of optimal and supra-optimal concentrations (0, 250, 500 and 750 mM) of NaCl on the growth, chlorophyll, soluble carbohydrate and proline content, ion concentrations and antioxidant enzyme defence of Sesuvium portulacastrum was studied. A significant increase in growth and tissue water content was observed in the shoots exposed to 250 mM salt. Minimum damage to the membrane in terms ...
objective: the present study was conducted to investigate the hepatoprotective activity of hydro-ethanolic fruit extract of rosa canina (r. canina) against carbon tetrachloride (ccl4)-induced hepatotoxicity in rats. methods: male wistar albino rats were randomly divided into six groups of 8 animals of each, including control, toxic (ccl4), r. canina 250, 500, and 750 mg/kg + ccl4 and r. canina ...
In a double-blind double-placebo crossover study naproxen (500-750 mg daily) was found to be equivalent to phenylbutazone (400-600 mg daily) in the control of disease activity in 20 patients suffering from ankylosing spondylitis during a two times 5-week trial period. No serious side effects were observed during the trial period. Gastric complaints occurred twice as often under phenylbutazone a...
The spectral resolution of the binaural system was measured using a tone-detection task in a binaural analog of the notched-noise technique. Three listeners performed 2-interval, 2-alternative, forced choice tasks with a 500-ms out-of-phase signal within 500 ms of broadband masking noise consisting of an "outer" band of either interaurally uncorrelated or anticorrelated noise, and an "inner" ba...
OBJECTIVE To evaluate changes in the speed of pupil constriction and in anterior segment parameters after laser peripheral iridotomy (LPI) in patients with angle closure using anterior segment optical coherence tomography. METHODS In this prospective observational study, videos of pupil and anterior segment changes in response to illumination were captured with real-time video recording using...
