Heat capacities of HfB2.035 and HfC0.968 from 5 to 350 K
(Elsevier, 1977-03)
Heat capacities were determined by adiabatic calorimetry on well-characterized samples of HfB2.035 and HfC0.968. The results are simply sigmoid except for a peak in the first derivative of the HfB2 smoothed results (not ...
The protective effects of dietary fish oil on focal cerebral infarction
(Elsevier, 1979-11)
The protective effect of the (n-3) fatty acids in menhaden fish oil on acute cerebral ischemia was investigated in cats. Cerebral ischemia was produced by ligation of the left middle cerebral artery of cats fed either a ...
The biosynthesis by brain microsomes of cerebrosides containing nonhydroxy fatty acids,
(Elsevier, 1970-12)
Incubation of microsomes from mouse brain with UDP-gal, a long-chain base, and 14C-fatty acyl-CoA resulted in formation of NFA-cerebroside labeled in the fatty acid residue. The rate of synthesis was ten times that of the ...
Succinic acid. Heat capacities and thermodynamic properties from 5 to 328 K. An efficient drying procedure
(Elsevier, 1970-09)
Heat capacities of succinic acid from 5 to 328 K were determined by adiabatic calorimetry. At 298.15 K, values of Cp, So, (Ho-H0o)/T and (Go-H0o)/T are 36.55, 39.99, 20.23, and -19.76 cal K-1 mol-1. No thermal anomalies ...
Purification of RNA polymerase from actinomycin producing and nonproducing cells of Streptomyces antibioticus
(Elsevier, 1979-11)
DNA-dependent RNA polymerase has been purified approximately 700-fold from 12-h-old cells of Streptomyces antibioticus and 400-fold from 48-h cells. Both enzymes appear nearly homogeneous as judged by sodium dodecyl ...
Normal coordinate analyses of molecules with the amide group
(Elsevier, 1971-01)
Normal coordinate analyses have been performed on molecules with the amide group using force constants transferred from N-methylacetamides and polyamides. The molecules involved were hexamethylenedipropionamide, ...
Quantitative analysis of pyridine nucleotides in red blood cells: A single-step extraction procedure
(Elsevier, 1976-03)
Quantitative analysis of red cell pyridine nucleotides has been unreliable in the past because of technical problems in extracting them in the presence of hemoglobin. A simple alcoholic extraction procedure for analysis ...
Natural occurrence of S-alkyl glycerol ethers in ehrlich ascites cells
(Elsevier, 1978)
1. 1. S-alkyl glycerol ethers were isolated by thin-layer chromatography from the total lipids of Ehrlich ascites cells following reduction with vitride.2. 2. Gas-liquid chromatography of the isopropylidene derivatives ...
Assay of glycogen phosphorylase by differential spectropolarimetry
(Elsevier, 1971-09)
A differential spectropolarimetric method has been developed for the measurement of glycogen phosphorylase activity. The reaction course measured in this way was first order, in agreement with results obtained by measuring ...
