Action of cations on the leachability of bio-stimulants in a soil column at soil-water interface and its impact on surface water quality
Excess of nutrients such as P and N causes eutrophication on the shores of lakes and ponds. Simulated soil column study showed that the physico-chemical properties of soil affects the movement of anions such as PO43- and NO31- by the soil pore water thereby affecting the leachability at soil water in...
Impact of elevated nitrate on sulfate-reducing bacteria: a comparative study of Desulfovibrio vulgaris.
Levels of nitric oxide metabolites in cerebrospinal fluid in cluster headache.
We collected CSF from 14 episodic CH patients. Lumbar puncture (LP) was performed at two occasions: in active period between headache attacks, and in remission, not earlier than three weeks after the last CH attack. Eleven healthy volunteers served as controls. To estimate NO production, we determin...
[The relation between nitric oxide levels in exhaled breath condensate and asthma control questionnaires in asthma patients].
The goal of asthma treatment is to achieve clinical control. The aim of this study was to compare the role of measurement of nitric oxide and its products in exhaled breath condensate and asthma control questionnaire (ACQ), level of asthma control (LAC) according to GINA guidelines and bronchial pro...
Seed germination of a newly discovered hyperaccumulator Solanum nigrum L. affected by illumination and seed-soaking reagent
Solanum nigrum is a newly found Cd-hyperaccumulator which showed very high remediation efficiency in polluted soil. Seed germination experiments with different illumination and seed-soaking reagents were conducted in constant temperature box and greenhouse with soil as burgeon base....
Characterization of the winter midwestern particulate nitrate bulge.
A previously unobserved multi-state region of elevated particulate nitrate concentration was detected as a result of the expansion of the Interagency Monitoring of Protected Visual Environments (IMPROVE) network of remote-area particulate matter (PM) speciation monitoring sites into the midwestern U...
[Nitrate removal from wastewater using rice straw as carbon source and biofilm carrier].
In this research,agriculture waste-rice straw was investigated as the sole carbon source as well as biofilm carrier to remove nitrate from wastewater in up-flow laboratory reactors. The experimental results indicated that the startup of the system was quick and a high nitrate removal efficiency was...
Lack of modulation of gastric emptying by dietary nitrate in healthy volunteers.
Nitric oxide produced endogenously in vagal neurons modulates gastrointestinal motor activity as an important non-adrenergic and non-cholinergic neurotransmitter. Other than through endogenous biosynthesis, a high concentration of nitric oxide also occurs by chemical reactions within the stomach in...
Bioremediation of nitroexplosive wastewater by an yeast isolate Pichia sydowiorum MCM Y-3 in fixed film bioreactor.
Nitroexplosives are essential for security and defense of the nation and hence their production continues. Their residues and transformed products, released in the environment are toxic to both terrestrial and aquatic life. This necessitates remediation of wastewaters containing such hazardous chemi...
Effects of an exercise intervention using Dance Dance Revolution on endothelial function and other risk factors in overweight children.
To determine whether an exercise intervention using an active video game (Dance Dance Revolution [DDR]) is effective in improving endothelial dysfunction (EDF) and other risk factors in overweight children. Thirty-five children (Body mass index > or = 85(th) percentil...
