Sulfurylation of estradiol-17B by extracts of ovary, corpus luteum, testis and adrenal cortex1
(Elsevier, 1965-01)
Soluble enzyme preparations from bovine ovary, corpus luteum and adrenal cortex and from rat testis sulfurylated estradiol-17[beta] in the presence of ATP and Mg++. Two major products were tentatively identified by ...
Genetic variation in the carbonic anhydrase isozymes of macaque monkeys. IV. Degradation by heat and proteolysis of normal and variant carbonic anhydrase isozymes of Macaca nemestrina
(Elsevier, 1984-04)
Studies were undertaken on the heat denaturation and proteolytic degradation by [alpha]-chymotrypsin of the normal red cell carbonic anhydrase isozyme, CA II, and two electrophoretic variants of carbonic anhydrase I, CA ...
Cadmium and arsenite binding by N-dihydrolipoyl-aminoethoxydextran: A model study of enzyme dithiol criteria
(Elsevier, 1973)
We have observed the interaction of Cd2+, Zn2+, and AsO22- with a dithiol-substituted polymer (N-dihydrolipoyl aminoethoxy dextran). Cadmium binding results in an intense uv difference spectrum ([lambda]max = 240 nm). ...
Synthesis of 6- or 7-substituted 1,2,3,4-tetrahydroisoquinoline- 3-carboxylic acids
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-03)
A straightforward approach for the synthesis of several new, aryl-substituted derivatives of the conformationally constrained phenylalanine analogue 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (Tic) is described. Tic, ...
Bone Marrow Transplantation Demonstrates That Carbonic Anhydrase II Deficiency Limited to Bone Marrow-Derived Cells Affects Ammonium Chloride Tolerance in Mice
(Elsevier, 1994-02)
Bone marrow transplantation (BMT) in mice was utilized to determine the relative importance of carbonic anhydrase II (CA II) deficiency in blood compared to kidney in the pathogenesis of the ammonium chloride intolerance ...
Raulin award lecture: Wilson's disease therapy with zinc and tetrathiomolybdate
(John Wiley & Sons, Inc., 2000)
Zinc and tetrathiomolybdate, effective, nontoxic drugs, have now been added to the treatment of most phases of Wilson's disease. Zinc is used for maintenance as well as treating presymptomatic, pregnant, and pediatric ...
Temperature-pressure studies on magnesium-activated adenosinetriphosphatase from skeletal muscle
(Elsevier, 1961-11)
The effects of pressure, temperature, and pH on the activity of purified rabbit skeletal muscle magnesium-activated ATPase were measured. The enzyme is rapidly and irreversibly inactivated by both temperature and pressure ...
Synthetic Strategies and Parameters Involved in the Synthesis of Oligodeoxyribo‐ and Oligoribonucleotides According to the H‐Phosphonate Method
(Wiley Periodicals, Inc.Humana Press, 2000-02)
Oligonucleotides can be synthesized by condensing a protected nucleoside H‐phosphonate monoester with a second nucleoside in the presence of a coupling agent to produce a dinucleoside H‐phosphonate diester. This can then ...
Improved high-performance liquid chromatographic assay for the quantification of 5-bromo-2'-deoxyuridine and 5-bromouracil in plasma
(Elsevier, 1988)
A sensitive and specific procedure using high-performance liquid chromatography (HPLC) was developed for the quantification of 5-bromo-2'-deoxyuridine (BUdR) and 5-bromouracil (BU) in plasma. BUdR and BU were first extracted ...
