Thermodynamics of ammonium halogenated tellurides II. Heat capacity, phase transitions, and thermodynamic properties of (ND4)2TeCl6 at temperatures from 5 K to 325 K
(Elsevier, 1992-06)
The heat capacity of deuterated ammonium hexachlorotellurate (ND4)2TeCl6 was measured at temperatures T from 5 K to 325 K by adiabatic calorimetry. A small anomaly in the curve of heat capacity against temperature was found ...
Observations consistent with autocrine stimulation of hybridoma cell growth and implications for large-scale antibody production
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-04)
Existence of autocrine growth factors (aGFs) may influence the serum requirement for growth of hybridoma cells and thus significantly influence process economics. For the murine hybridoma cell line S3H5/γ2bA2, critical ...
Papaverine effects on PGI2 and TXA2 release from the canine vascular wall
(Elsevier, 1992-07)
Operative manipulation of blood vessels might lead to spasm, thereby destroying the endothelial cell function: the spasm can be prevented by the vasodilator papaverine. To study if this was mediated via the prostanoid ...
Evidence for "stable" organocopper intermediates in the reaction between Me2CuLi[middle dot]LiI and allylic sulfinyl mesylates.
(Elsevier, 1992-08-18)
The addition of Me2CuLi[middle dot]LiI to acyclic allylic sulfinyl mesylates bearing a phenyl functionality in the molecule gives rise to chiral allenes 4 and 11 in variable yields and optical purities, presumably via an ...
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 ...
