Pyrimidine in aqueous media
(Elsevier, 1969-04)
The electrochemical reduction of pyrimidine in aqueous media was studied using alternating current (a.c.) polarography. Over the pH-range, 0.5-13, five moderately to highly irreversible a.c. waves were observed, which ...
Testosterone metabolism in target tissues: Hypothalamic and pituitary tissues of the adult rat and human fetus, and the immature rat epiphysis
(Elsevier, 1969-11)
Rat pituitary, hypothalamic and cerebral cortical minces are demonstrated to effect the conversion of testosterone (T) to 5[alpha]-androstan-17[beta]-o1-3-one (DHT) and [Delta]4-androstene-3,17-dione ([Delta]4A). The ...
A low-angle X-ray diffraction study of the swelling behavior of peripheral nerve myelin
(Elsevier, 1969-04-15)
The swelling behavior of peripheral nerve myelin has been studied by recording low-angle X-ray diffraction patterns of nerve after various chemical treatments. Peripheral myelin swells in distilled water, hypotonic Ringer's ...
A stereospecific 2-keto-4-hydroxyglutarate aldolase from Escherichia coli
(Elsevier, 1969-07-08)
Enzymic [omega]-oxidation: Stoichiometry of the [omega]-oxidation of fatty acids
(Elsevier, 1969-04)
The stoichiometry of the [omega]-oxidation of fatty acids catalyzed by the inducible enzyme system of Pseudomonas oleovorans was determined. Assay methods are described for the polarographic measurement of oxygen uptake ...
Experimental and theoretical investigation of purification in a column crystallizer of material with impurities of the eutectic forming type
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1969-07)
A theoretical analysis of the operation of a Schildknecht type of column crystallizer is presented and simplified to three special cases. Experimental determinations were made of concentration profiles established during ...
Phospholipid metabolism in the developing liver : I. The biosynthesis of choline glycerophosphatides by liver slices from fetal, newborn and adult rats
(Elsevier, 1969-07-29)
1. 1. The biosynthesis of choline glycerophosphatides was evaluated in fetal, neonatal and adult female rat liver. The two main pathways were assessed by studying the rates of incorporation of [Me-14C]choline and ...
Acute and short-term oral toxicity of 2-n-ethylaminoethanol in rats
(Elsevier, 1969)
Acute oral doses of neutralized 2-N-ethylaminoethanol (EAE) in rats greatly increased gastric secretion, resulting in dehydration and death after 3-4 days. The effect of EAE on gastric secretion did not appear to be due ...
Predictions of the particle size distribution changes in emulsions and suspensions by digital computation
(Elsevier, 1969-03)
The fundamental Smoluchowski flocculation rate equations including the effects of polydispersity and particle-particle potential energy barrier have been solved for any initial particle size distribution. The procedure for ...
Hapten-radioimmunoassay: A general procedure for the estimation of steroidal and other haptenic substances
(Elsevier, 1969-06)
Hapten-radioimmunoassay may be used for sensitive and specific quantitation of low molecular weight substances which can be made immunogenic by conjugation to a protein, This method, which involves radioiodination of the ...
