BACKGROUND Compared with aspirin alone, use of the new antiplatelet regimens, including aspirin combined with dipyridamole and clopidogrel bisulfate, has been found to further reduce the risk of stroke and other vascular events in patients who have experienced stroke or transient ischemic attack. However, their cost-effectiveness ratios relative to aspirin alone have not been estimated. METHO...

In a case of quinine-induced agranulocytosis marrow culture studies confirmed the inhibitory effect on the patient's cells of equivalent therapeutic plasma concentrations of quinine. Similar concentrations had no effect on normal marrow cells. Quinidine, the stereoisomer of quinine, had no effect on either cells from the patient or normal cells. The results encourage the use of in-vitro bone ma...

In the atmosphere, a well-known and conventional pathway toward the formation of ammonium sulfate is through the neutralization of sulfuric acid with ammonia (NH3) in water droplets. Here, we present direct ab initio molecular dynamics simulation evidence of the formation of ammonium bisulfate (NH4HSO4) from the hydrated NH3 and SO3 molecules in a water trimer as well as on the surface of a wat...

As part of the Southern Appalachian Mountains Initiative, a comprehensive air quality modeling system was developed to evaluate potential emission control strategies to reduce atmospheric pollutant levels at the Class I areas located in the Southern Appalachian Mountains. Six multiday episodes between 1991 and 1995 were simulated, and the skill of the modeling system was evaluated. Two papers c...

Abstract In this paper, the research progress of ammonium bisulfate (ABS) volatilization in coal-fired power plants SCR denitrification process was reviewed. Combination with self-made experiments, SEM, flue gas analyzer and TG-DTG curves ABS ion chromatography. The condensation characteristics were investigated carefully. Results show that as temperature increased by 50 o C, ABS/AS rate an ord...

background: studies have demonstrated that sickle cell trait can be found in an asymptomatic healthy carrier with normal complete blood count (cbc) and red blood cell (rbc) indices. according to iranian ministry of health bulletin instructions, prenuptial thalassemia screening program (tsp) primarily depends on rbc indices which are measured through a routine cbc. only when these levels are bel...
