Background: Xuefu Zhuyu decoction (XZD) is a popular Chinese medicinal formula and often compared with nitrates in treating coronary heart disease angina pectoris. This systematic review aims to evaluate the efficacy of XZD in treating angina pectoris according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) systematic review standard. Methods: Randomized cont...

conclusions it was shown that the removal efficiency of nitrate was directly proportional to the amount of chaff, temperature, and contact time but inversely to the ph. this study showed that nitrate removal by chaff is a promising technique. results the result of this study revealed that chaff as an absorbent could remove nitrate from solutions, and the efficiency of adsorption increased as co...

This paper describes the development of a field-scale model that simulates the nitrogen (N) cycle in grazed grassland within a catchment-scale management model which can predict the loading and concentration of nitrate in rivers. The development is comprised of the addition of two sub-models of nitrate transport: one relating the amount of soil nitrate to its concentration in drainage water for...

The formation of secondary organic aerosol (SOA) from the oxidation of β-pinene via nitrate radicals is investigated in the Georgia Tech Environmental Chamber (GTEC) facility. Aerosol yields are determined for experiments performed under both dry (relative humidity (RH) < 2 %) and humid (RH= 50 % and RH= 70 %) conditions. To probe the effects of peroxy radical (RO2) fate on aerosol formation, “...

Although the nitrate and nitrite have been used for centuries, it has only recently been discovered that nitrate is manufactured in mammals by the oxidation of nitric oxide and that the nitrate formed also has the potential for disinfecting the food we eat. The mechanisms by which nitric oxide and other nitrogen oxides provide selective toxicity towards pathogens is not yet completely understoo...

This paper presents a novel procedure for the treatment of contaminated water with high concentrations nitrates, which are considered as one main causes eutrophication phenomena. For this purpose, magnetic nanoparticles functionalized silver (Fe3O4@AgNPs) were synthesized and used an adsorbent nitrates. Experimental conditions, including pH, adsorbate dose, temperature contact time, analyzed to...

Organic nitrates have served as mainstays of therapy for the treatment of coronary artery disease for more than a century. Their use, however, has been complicated by unwanted side effects, including hypotension and the development of nitrate tolerance. Nitrate tolerance is a term used to define tachyphylaxis to nitrates with long-term use. The mechanisms of nitrate tolerance have been debated ...

NH3-Selective Catalytic Reduction (SCR) is applied worldwide to DeNOx of combustion exhausts from stationary and mobile sources, but a greater DeNOx activity at low temperatures is desired to meet forthcoming restrictive legislations. We have obtained high NO reduction efficiencies at 200 – 300 °C over commercial V-based and Fe-exchanged zeolite catalysts by reacting NO with both ammonia and ni...
