Cholesterol biosynthesis in human fetal liver and adrenal
(Elsevier, 1971-07)
Hepatic and adrenal cholesterol biosynthesis were investigated in the human fetus in vitro by measuring the incorporation of acetate-2-14C into cholesterol by slices of liver and adrenals from the same fetus. To differentiate ...
An N-acetyl--glucosamine binding lectin from Bandeiraea Simplicifolia seeds
(Elsevier, 1976-11)
A second lectin with a high activity for nonreducing 2-acetamido-2-deoxy-[alpha]--glucopyranosyl residues has been isolated from the seed extracts of Bandeiraea simplicifolia by affinity chromatography on chitin. The lectin ...
Synthesis and properties of 35S, 14C and 3H labeled S-alkyl glycerol ethers and derivatives
(Elsevier, 1976-07)
Radioactive S-alkyl glycerol ethers have been synthesized with 35S, 14C and 3H labels as well as 3H/35S double labels.The synthesized compounds were converted to various derivatives which can serve to characterize the ...
Rat liver membrane preparations
(Elsevier, 1972-09)
The quality of rat liver plasma membranes was examined using three different methods of preparation. Hypotonic Ca++-free preparation media were compared with hypotonic Ca++ media and with isotonic Ca++ media. The plasma ...
Evidence for two sites of inhibition of photosynthetic electron transport by dibromothymoquinone
(Elsevier, 1978-08)
Two sites in the photosynthetic electron transport chain of spinach chloroplasts are sensitive to inhibition by the plastoquinone antagonist dibromothymoquinone (2,5-dibromo-3-methyl-6-isopropyl-p-benzoquinone). This ...
Manganous chloride spray reagent for cholesterol and bile acids on thin-layer chromatograms
(Elsevier, 1970-12-02)
The effect of daily ingestion of caffeine on the microsomal enzymes of rat liver
(Elsevier, 1973-02)
The effect of repeated ingestion of caffeine on rat-liver microsoma enzymes was studied. In the rat, ingestion of 20-24 mg caffeine/kg/day in the drinking water for more than 2 wk inhibited aminopyrine N-demethylase activity. ...
Iodine analysis of biological samples by neutron activation of 127I, with scintillation counting of cerenkov radiation
(Elsevier, 1971-03)
The naturally occurring isotope, 127I, has been measured by neutron activation, postirradiation extraction of 128I plus 127I (added carrier), and timed scintillation counting of aqueous solution utilizing Cerenkov radiation. ...
