some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
1. In kidney-cortex slices from the well-fed rat, glucose (5mm) supplied 25-30% of the respiratory fuel; in the starved state, the corresponding value was 10%. These results are based on measurements of the net uptake of glucose and of the specific radioactivity of labelled carbon dioxide formed in the presence of [U-(14)C]-glucose. 2. Added acetoacetate (5mm) or butyrate (10mm) provided up to ...
1. The rates of formation of acetoacetate and beta-hydroxybutyrate by the isolated perfused rat liver were measured under various conditions. 2. The rates found after addition of butyrate, octanoate, oleate and linoleate were about 100mumoles/hr./g. wet wt. in the liver of starved rats. These rates are much higher than those found with rat liver slices. 3. The differences between the rates give...
one series of half-analogues of michler’s ketone containing one or more terminal methoxysubstituents with variable tertiary amino groups have been used in this study. nmr spectralresults for the parent ketones confirm earlier findings that ortho proton shifts are apparentlyindependent from steric effects in derivatives of michler’s ketone because the ring current andcarbonyl-induced shifts are ...
abstract the present thesis studies different question sentences in persian and russian languages comparatively. sentence is a syntactic unit that matches a lot of dimensions together. sentence includes syntactic structure definite meaning & concept and different applied demotions. in applied, question and imperative sentences based on speakers aim. predicative sentences state a kind of info...
palladium (ii) coordination complexes catalyze the reaction of alcohols with ketones to yield ethers. during the catalytic cycle, the alcohol adds selectively to the β-carbon (anti-markovnikov). in this work, mechanism and kinetics for the reaction of methanol with methyl vinyl ketone (mvk), being catalyzed by pd, has been theoretically investigated in detail. using quantum mechanical approach,...
Background and Aims:Nowadays, many different techniques to extraction of chemical compounds from aquatic samples have been introduced, for examples techniques based on the use of needles that were packed with some sorbents. Considering that so far no synthesis sorbent based on single-walled carbon nanotubes and sol-gel techniques for the extraction of toluene and methyl ethyl ketone from ...
BACKGROUND Diabetes mellitus is a major risk factor for cardiovascular mortality by increasing endothelial cell (EC) dysfunction and subsequently accelerating atherosclerosis. Extracellular-signal regulated kinase 5 (ERK5) is activated by steady laminar flow and regulates EC function by increasing endothelial nitric oxide synthase expression and inhibiting EC inflammation. However, the role and...
