Association of the transformed glucocorticoid receptor with a cytoskeletal protein complex
(Elsevier, 1992-03)
In a recent paper we described a system in which glucocorticoid receptors associate with particulate complexes containing tubulin [Cancer Res. 49 (1989) 2222s-2229s]. When L cell cytosol is mixed with a microtubule stabilizing ...
Thermodynamics of ammonium halogenated tellurides I. Heat capacity and thermodynamic properties of (NH4)2 TeCl6 at temperatures from 5 K to 350 K
(Elsevier, 1992-06)
The heat capacity of ammonium hexachlorotellurate (NH4)2TeCl6 was measured at temperatures from 5 K to 350 K. The heat-capacity curve shows a small anomaly around 86 K and a broad peak extending from 100 K to 280 K. The ...
Preparation and reactions of 1,1-zinc, boron and 1,1-copper, boron alkenyl bimetallics
(Elsevier, 1992-06-23)
Pinacol [alpha]-iodoalkenylboronates 8, readily prepared by the hydroboration of 1-iodoalkynes, were converted to 1,1-bimetallics of boron and zinc or copper which react with a wide range of electrophiles affording ...
On the factors that affect the mode of cyclization of [alpha]-silyl radicals: A method for angular hydroxymethylation by the 5-exo cyclization
(Elsevier, 1992-10-27)
The steric and stereochemical factors which favor the 5-exo cyclization of a 5-substituted 2-sila-5-hexen-1-yl radical have been probed. This radical cyclization approach constitutes a highly efficient and convenient means ...
Inhibition of organic anion transport in endothelial cells by hydrogen peroxide
(Elsevier, 1992-11-01)
ATP loss is a prominent feature of cellular injury induced by oxidants or ischemia. How reduction of cellular ATP levels contributes to lethal injury is still poorly understood. In this study we examined the ability of ...
Lectin-based homogeneous enzyme-linked binding assay for estimating the type and relative amount of carbohydrate within intact glycoproteins
(Elsevier, 1992-04)
The feasibility of using a new lectin-based homogeneous enzyme-linked binding assay for estimating the type and relative amount of specific carbohydrate structures within intact glycoproteins is examined. Malate ...
Design, synthesis and activity against human cytomegalovirus of non-phosphorylatable analogs of toyocamycin, sangivamycin and thiosangivamycin
(Elsevier, 1992-12)
A number of 7-alkyl 4-aminopyrrolo[2,3-pyrimidine derivatives related to toyocamycin, sangivamycin and thiosangivamycin have been prepared and tested for their activity against human cytomegalovirus (HCMV). Only the thioamide ...
Phase II trial of N-methylformamide in lung cancer
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-08)
The effect of 2,2'-dichlorodiethyl sulfide on DNA synthesis of a murine stratified keratinocyte culture system
(Elsevier, 1992-09-28)
A primary stratified keratinocyte culture resembling the epidermis in situ was used as a model for studying the effects of exposure to 2,2'-dichlorodiethyl sulfide, or sulfur mustard (SM), on DNA synthesis. A method that ...
Comparison of heat capacities measured by adiabatic calorimetry and by scanning calorimetry: thermodynamic properties of 9-methylcarbazole at temperatures between 4 K and 345 K
(Elsevier, 1992-03)
We have measured the heat capacity of 9-methylcarbazole at 4[less-than-or-equals, slant]T/K[less-than-or-equals, slant]345 by adiabatic calorimetry and compared it with that measured by differential scanning calorimetry ...
