Isolation and characterization of a second lectin (SNA-II) present in elderberry (Sambucus nigra L.) bark
(Elsevier, 1990-03)
A second lectin (SNA-II) has been isolated from elderberry (Sambucus nigra L.) bark by affinity chromatography on immobilized asialo-glycophorin. This lectin is a blood group nonspecific glycoprotein containing 7.8% ...
Thermodynamic properties of ammonium haloplatinates: II. Heat capacity and thermodynamic functions of deuterated ammonium hexachloroplatinate (ND4)2PtCl6 at temperatures from 5 K to 350 K
(Elsevier, 1991-07)
The heat capacity of deuterated ammonium hexachloroplatinate (ND4)2PtCl6 was measured at temperatures from 5 K to 350 K by adiabatic calorimetry. One λ-shaped anomaly, absent in the undeuterated salt, was found in ...
Synthesis and in vivo evaluation of a 99m/99Tc-DADT-Benzovesamicol: a potential marker for cholinergic neurons
(Elsevier, 1994-02)
The diaminodithiol (DADT) ligand has been conjugated to the neuromuscular blocking agent benzovesamicol (BVM) in the 5-position. DADT-BVM 1 was synthesized by coupling of 5-aminomethylbenzovesamicol with a BCA thiolactone ...
A quantitative dot-blot immunoassay for integral membrane proteins: Preparation of pancreatic plasma membranes containing apical and basolateral domains
(Elsevier, 1991-01)
Modifications of standard dot-blot immunoassay techniques have been made for the quantitation of integral membrane protein antigens. The modification involves the signal development step, which is performed by using ...
Hadamard transform photothermal deflection desitometry of electrophretically blotted proteins
(Elsevier, 1990)
Hadamard transform spatial multiplexing techniques are applied to laser densitometry in order to prevent the photo-induced degradation of sensitive materials. Photochemical and thermal degradations can often occur in point ...
Discordant changes in plasma ACTH and [beta]-lipotropin/[beta]-endorphin levels in Clshing's disease patients with depression
(Elsevier, 1992-11)
Cushing's Disease is often associated with a depressive syndrome, with mood, vegetative, and cognitive abnormalities of variable severity. In 11 patients with (pituitary ACTH-dependent) Cushing's disease (10 women, 1 man), ...
Cracks developed during SrTiO 3 thin-film preparation from polymeric precursors
(John Wiley & Sons, Ltd., 1999-05)
Strontium titanate (SrTiO 3 ) thin films were prepared by dip-coating Si(111) single-crystal substrates in citrate solutions of ethylene glycol, considering several citric acid/ethylene glycol (CA/EG) ratios. Measurements ...
A synthesis of (+)-7-Epiaustraline and (-)-7-Epialexine
(Elsevier, 1991-09-30)
Reductive cyclization of the azido epoxides 19[alpha] and 19[beta] followed by deprotection afforded the HIV inhibitor (+)-7-epiaustraline 7 and (-)-7-epialexine 9. The formation of 7 proceeded with an unusual inversion ...
Synthesis of a disulfide cross-linked DNA triple helix
(Elsevier, 1994-06-27)
An intramolecular DNA triple helix incorporating a disulfide cross-link has been synthesized. Potassium permanganate footprinting and UV melting analysis demonstrate that the cross-link increases the conformational stability ...
α- d -Galactosylation of surface fucoglycoconjugate(s) upon stimulation/activation of murine peritoneal macrophages
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1992-04)
Murine resident macrophages express, on their surface, carbohydrate epitopes which undergo changes during their stimulation/activation as monitored by binding of 125 I labelled Evonymus europaea and Griffonia simplicifolia ...
