S18.20 Preparation of two kinds of sialic acid specific monomeric monovalent lectin derivatives and their application to the study of cell surface glycoconjugates by flow cytometry
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1993-08)
Diimide formation on the Ni(100) surface
(Elsevier, 1993-06-10)
Diimide (N2H2), an extremely reactive species, is observed as a gas phase product from the Ni(100) surface in the 200 to 450 K range during hydrazine thermal decomposition and during thermal desorption of predissociated ...
Progesterone modulation of gonadotropin secretion by dispersed rat pituitary cells in culture. IV. Follicle-stimulating hormone synthesis and release
(Elsevier, 1993-02)
Estradiol-treated, rat pituitary cells were studied to examine the effects of progesterone (P) on follicle-stimulating hormone (FSH) synthesis and secretion. Progesterone was administered prior to or concurrent with 3 h ...
Rapid analysis of leukocyte-endothelial adhesion
(Elsevier, 1993-02-26)
Neutrophil adherence to endothelial monolayers in multi-well plates can be rapidly quantitated, using a fluorescent plate reader. The number of adherent neutrophils which have been labeled with biscarboxyethyl carboxyfluorescein ...
Adsorption and thermal decomposition of CH3SH on the Pt(111) surface
(Elsevier, 1993-12-01)
Adsorption, desorption and thermal decomposition of methanethiol (CH3SH) on a clean and on a (2 x 2)-S covered Pt(111) surface have been studied using temperature programmed desorption, high resolution electron energy ...
The effects of transforming growth factor alpha and somatostatin on regenerating hepatocytes in the rat
(Elsevier, 1993-03-05)
Transforming growth factor alpha (TGF[alpha]) stimulates DNA synthesis in adult rat hepatocytes, and plays a physiological role after partial hepatectomy by an autocrine mechanism. Somatostatin (SS-14) is a potent inhibitor ...
Axial selectivity of 1,2-nucleophilic additions to 2-(Alkylidene)cyclohexanones: Is it higher than that of 2-cyclohexenones?
(Elsevier, 1993-04-23)
2-(Alkylidene)cyclohexanones embedded in steroid systems underwent 1,2-addition of both small and sterically demanding nucleophiles to yield exclusively the axial adducts, supporting the suggestion that 2-(alkylidene)cyc ...
The preparation of (Z)-2-lithio-ortho-styryllithium via an ortho-directed lithiation
(Elsevier, 1993-11-30)
Lithiation of (Z)-2-lithiostyrene with t-butyllithium/TMEDA pentane led directly to (Z)-2-lithio-ortho-styryllithium. Subsequent treatment of this dilithio compound with difunctional electrophiles allowed the preparation ...
