Some chiral β-amino alcohols have been evaluated as potential ligands for the ruthenium-catalyzed asymmetric transfer hydrogenation (ATH) of N-phosphinyl ketimines in isopropyl alcohol. The ruthenium complex prepared from [RuCl2(p-cymene)]2 and (1S,2R)-1-amino-2-indanol has shown to be an efficient catalyst for the ATH of several N-(diphenylphosphinyl)imines, affording the reduction products in...

OBJECTIVE Adenotonsillar hypertrophy (ATH) is the leading cause for obstructive sleep apnea syndrome (OSAS) in children. The peak age for adenoid and tonsillar hypertrophy and related OSAS is 3-6 years. It has been suggested that OSAS due to ATH is extremely rare in infants. The purpose of the present study was to delineate OSAS due to ATH in infants. METHODS Twenty-nine consecutive infants <...

  Abstract: Spectrophotometric studies were successfully used in quantitative analysis of Amitriptyline Hydrochloride (ATH) Two new methods using spectrophotometry are described for the determination of (ATH) with potassium bromate as the oxidizing agent and acid dyes, Methyl orange and Indigo carmine. Both spectrophotometric methods are based o...

High performance glass fiber reinforced epoxy composites are in greater demand several industrial applications, from civil structures to aviation industry. The has highly cross-linked structure and is found be high polymer. Further, carbon nanofillers such as multi-walled nanotubes (MWCNT), graphene nanoplatelets (GNP) thermally stable microfiller aluminium trihydrate (ATH) being used improve t...

Cross contamination of intramyocellular lipid (IMCL) signals through loss of bulk magnetic susceptibility (BMS) differences was detected in human muscles using proton magnetic resonance spectroscopic imaging ((1)H-MRSI) at 4 T by varying nominal voxel sizes on healthy subjects. In soleus muscle the IMCL content estimated in 1.00-ml-sized voxels was 15% and 30% higher than that in 0.25-ml voxels...

Originally isolated on the basis of its capacity to stimulate T-cell maturation and proliferation, avian thymic hormone (ATH) is nevertheless a parvalbumin, one of two beta-lineage isoforms expressed in birds. We recently learned that addition of Ca(2+)-free ATH to a solution of 8-anilinonaphthalene-1-sulfonate (ANS) markedly increases ANS emission. This behavior, not observed in the presence o...

This study proposes an innovative solution to flame-retard a sandwich composite made of unsaturated polyester resin, glass fibre skins and nonwoven core material. The strategy uses the material as flame-retardant carrier, while resin is also flame-retarded with aluminum trihydroxide (ATH). A screening fire-retardant performances materials, covered different types phosphorous additives (phosphat...
