A two-step HPLC separation that combines isocratic and gradient elution has been developed for the analysis of trace impurities in fatty alcohol ethoxylates (FAEs). Quantitative estimates of the early eluting impurities were obtained from a calibration curve based on the responses of an evaporative light scattering detector (ELSD). Isocratic conditions were used to elute the impurities and grad...

thermal conformational changes in human serum albumin (hsa) in present with a 10 mm phosphate buffer, at ph=7 have been investigated via circular dichroism (cd) and uv spectroscopic methods. the results indicate that temperature in a range of 25oc to 55oc could induce a reversible conformational change in the structure of hsa. the hsa phase transition corresponds to the physiological and pathol...

BACKGROUND AND PURPOSE Body temperature is a strong predictor of outcome in acute stroke. However, it is unknown whether antipyretic treatment leads to early and clinically worthwhile reduction of body temperature in patients with acute stroke, especially when they have no fever. The main purpose of this trial was to study whether early treatment of acute ischemic stroke patients with acetamino...

atopic eczema (ae) is a chronic inflammatory skin disease that affects children and adults, and  alters  quality  of  life.  previous  studies  have suggested several  socio-demographic   and environmental factors related to the prevalence of ae and other allergic diseases,  including acetaminophen use. in the present study, we report the rates of isolated ae, ae associated with asthma and ae a...

background acetaminophen exposure might be associated with increasing risk of asthma prevalence and other atopic disorders over recent decades. the present study aimed to investigate the association between acetaminophen exposure and the risk of developing childhood asthma. methods a case - control study was undertaken between march and september 2010 in urmia district north west of iran. subje...

Pharmaceutical compounds have been found in rivers and treated wastewaters. They often contaminate irrigation waters consequently accumulate edible vegetables, causing changes plants metabolism. The main objective of this work is to understand how lettuce cope with the contamination from three selected pharmaceuticals using a label free proteomic analysis. A hydroponic culture, grown for 36 day...
