Crystal and molecular structure of analgesics. II. Dezocine hydrobromide
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1981-08)
The cluster-tray method for rapid measurement of solute fluxes in adherent cultured cells
(Elsevier, 1981-08)
The use of an inexpensive and simple modification of Costar 24-well cluster trays is described in a rapid and reproducible method for measuring substrate fluxes in adherent cultured eukaryotic cells.
Cycloaddition of vinyl aziridines with unsaturated substrates. A novel rearrangement of an unsaturated nitro compound.
(Elsevier, 1981)
Vinylaziridine undergoes reaction with electrophilic acetylenes and olefins to produce 7-membered azepine derivatives. With [beta]-nitro-styrene however, a novel rearrangement occurs, presumably via an ene reaction to ...
On the dynamic structure factor, S(q,[omega]), of polymers in dilute solution
(Elsevier, 1981-08)
In principle, interpretation of dynamic scattering experiments requires theoretical calculation of either intermediate scattering functions S(q,t) or dynamic structure factors S(q,[omega]). Although dynamic scattering ...
A sensitive coupled HPLC/RIA technique for separation of endorphins: Multiple forms of B-endorphin in rat pituitary intermediate vs. anterior lobe
(Elsevier, 1981-08)
A technique is described which couples High Performance Liquid Chromatography (HPLC) to radioimmuno assays (RIA), thus achieving high sensitivity with good specificity. This method allows the separation and detection of ...
Evidence for a regulatory role of CTP : Choline phosphate cytidylyltransferase in the synthesis of phosphatidylcholine in fetal lung following premature birth
(Elsevier, 1981-07-24)
The sequence of reactions which function to incorporate choline into phosphatidylcholine was investigated in lung from fetuses following premature delivery. The rate of [methyl-14C]choline incorporation by rat lung slices ...
Characteristics of an aminohydrolase distinct from adenosine deaminase in cultured human lymphoblasts
(Elsevier, 1981-04-14)
An inherited deficiency of adenosine deaminase (adenosine aminohydrolase, EC 3.5.4.4) is associated with an autosomal recessive form of severe combined immunodeficiency disease. Affected patients exhibit markedly reduced ...
Dissolution kinetics: Catalysis by salts
(Elsevier, 1981-07)
The dissolution of silicate minerals by hydrofluoric acid has been found to be catalyzed by salts such as NH4Cl, NaCl, and LiCl as well as by strong acids. This catalysis is a strong function of pH and is attributed to the ...
An improved electron diffraction--microwave and molecular orbital study of the structure of SF5Cl
(Elsevier, 1981-09)
A new study of the structure of SF5Cl is reported. Previously-obtained electron diffraction data have been corrected for multiple scattering, and newly-reported microwave rotational constants have been combined in the ...
The content of diacylglycerol, triacylglycerol and monoacylglycerol and a comparison of the structural and metabolic heterogeneity of diacylglycerols and phosphatidylcholine during rat lung development
(Elsevier, 1981-04-23)
The content of diacylglycerol in fetal rat lung is approx. 36% of the adult and rapidly increases to adult levels by 1 day after birth. Triacylglycerol content is also low (23%) and increases to adult levels between 1 and ...
