An inorganic functional group approach to the systematic synthesis and reactivity studies of binuclear Mo/S and Mo/S/O complexes
(Elsevier, 1989)
A number of general reactions, based on molybdenum-coordinated sulphido or polysulphido ligands, can account for the synthesis of many members of the [Mo2V(S)n(S2)6-n]2-, [Mo2V(O)(S)n(S2)5-n]2- and [Mo2V(O)2(S)n(S2)4-n]2- ...
RO-Vibrational state densities based on spectroscopic data for non-separable systems
(Elsevier, 1989-07-21)
A Monte Carlo procedure for calculating the density of states is described. The method is based on an expansion of the eigenstate energies as term values, and coupling among vibrations and rotations is explicitly included. ...
The total synthesis of the water mold sex hormone oogoniol
(Elsevier, 1989)
The water mold sex hormone oogoniol (1a) has been synthesized from adrenosterone in 18 steps in 7.0% overall yield. The crucial step introduces the stereochemistry at C-15 and C-20 through a highly efficient 1,4-addition ...
Analysis of cancer-associated colonic mucin by ion-exchange chromatography: evidence for a mucin species of lower molecular charge and weight in cancer
(Elsevier, 1989-05-31)
Cancer-associated mucins in the colon are antigenically distinct and glycosylated differently from their normal counterparts. Mucin-rich glycoconjugate preparations were made from nine non-neoplastic colons, seven colon ...
Mitoxantrone, cisplatin, and methyl-glyoxal bis-guanylhydrazone chemotherapy for refractory malignant lymphoma: A Southwest Oncology Group phase II trial
(Kluwer Academic Publishers; Springer Science+Business Media, 1989-07)
A phase II trial of combination chemotherapy with mitoxantrone, cisplatin, and methyl-glyoxal bix-guanylhydrazone (MGBG) was conducted in 32 patients with unfavorable histology malignant lymphoma. All patients had relapsed ...
Gas chromatographic determination of gallopamil and norgallopamil in human plasma
(Elsevier, 1989)
A highly sensitive gas chromatographic assay is described for the simultaneous determination of gallopamil, a calcium channel blocking agent, and its major metabolite, norgallopamil. A multi-step extraction procedure is ...
Sulfite-sensitive solvent/polymeric-membrane electrode based on bis(diethyldithiocarbamato)mercury(II)
(Elsevier, 1989)
A new solvent/polymeric-membrane electrode which exhibits significant potentiometric response toward sulfite ion in the 1 x 10-6-1 x 10-3 M range is described. The membrane is prepared by incorporation of neutral ...
Characterization of cytosolic forms of CTP: choline-phosphate cytidylyltransferase in lung, isolated alveolar type II cells, A549 cell and Hep G2 cells
(Elsevier, 1989-12-18)
The subcellular forms of cytidylyltransferase (EC 2.7.7.15) in rat lung, rat liver, Hep G2 cells, A549 cells and alveolar Type II cells from adult rats were separated by glycerol density centrifugation. Cytosol prepared ...
The thermodynamics of the divalent metal fluorides. III. Heat capacity of the fast ion conductor SrSnF4 from 6 to 344 K
(Elsevier, 1989-07)
The heat capacity of the fast ion conductor SrSnF4 was measured by adiabatic calorimetry from 6 T/K 19F spin-lattice relaxation time T1 occurs. Standard molar thermodynamic functions are given at selected temperatures from ...
