BACKGROUND Asthma is a complex multifactorial disease that is not yet fully understood. Oxidative stress due to an imbalance between the oxidative forces and the antioxidant defense systems has been implicated in asthma pathogenesis. However, much debate still surrounds the key genetic factors involved in the development of this disease. Candidate genes include the glutathione S-transferases (G...

Nanostructured Ni2As2O7 semiconductor samples were synthesized by a solid state method among As2O3 and Ni(NO3)2.6H2O raw materials at 650 °C (S1) and 750 °C (S2) as reaction temperatures. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and F...

mnco2o4 (mno-co2o3) nanocomposite as a binary oxide has been successfully prepared by precipitation method using cobalt nitrate and manganese nitrate as the precursors and then characterized by scanning electron microscopy-energy dispersive micro-analysis (sem-edx) and x-ray diffraction (xrd) techniques. in this work, we report the hydrolysis kinetics reactions of semi mustard (chloroethyl ethy...

services companies attempt to promote their delivered services to customers and achieve a stable competitive advantage. for achieving this goal, marketing and hr scholars jointly propose application of internal marketing (im) principles and instruments. although im is a 30 years old concept in management, but it's measurement and application method have faced with different structural and ...

A diastereoselective Henry reaction of chiral aldehydes with nitroalkanes was developed using a chiral sulfonyldiamine (L1)-CuCl complex. The reaction of (R)-2-phenylpropanal and nitromethane was smoothly catalyzed by the (S,S,S)-L1-CuCl complex to give the adduct with 99/1 syn/anti selectivity in 99% ee. In the reaction of (S)-2-phenylpropanal and nitroethane, the (R,R,R)-L1-CuCl catalyst yiel...

The synthesis of 1,4,7-trimethyloxatriquinane (1), a 3-fold tertiary alkyl oxonium salt, is described. Compound 1 is inert to solvolysis with alcohols, even at elevated temperatures, but undergoes facile substitution with the strongly nucleophilic azide anion. Since an S(N)1 pathway is excluded, the only reasonable mechanistic interpretation for the reaction between 1 and N(3)(-) is S(N)2, desp...
