New mannose-specific lectins from garlic (Allium sativum) and ramsons (Allium ursinum) bulbs
(Elsevier, 1992-05-22)
Two new mannose-binding lectins were isolated from garlic (Allium sativum, ASA) and ramsons (Allium ursinum, AUA) bulbs, of the family Alliaceae, by affinity chromatography on immobilized mannose. The carbohydrate-binding ...
Preparation and Reactivity of Polyfunctional Zinc and Copper Organometallics Bearing Sulfur Functionalities
(Elsevier, 1992)
Iodomethylthiobenzoate 5 and [alpha]-chloroalkyl phenyl sulfides 6 were found to insert zinc dust in THF under very mild conditions (10-25 [deg]C, 0.5-2 h) leading to zinc [alpha]-thioorganometallics. After a transmetallation ...
A convenient, highly stereoselective synthesis of anti-[alpha],[beta]-epoxy alcohols by the Luche reduction of [alpha],[beta]-epoxy ketones
(Elsevier, 1992-10-27)
Reduction of [alpha],[beta]-epoxy ketones under the Luche conditions with NaBH4/CeCl3 in MeOH provides anti- (or erythro-) [alpha],[beta]-epoxy alcohols in high yields and with extremely high stereoselectivity.
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 ...
The medicinal flora of Majouri-Kirchi forests (Jammu and Kashmir State), India

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 ...
Euphoriant effects of nicotine in smokers
(Springer-Verlag, 1992-09)
Two studies were conducted to replicate and extend previous demonstrations of smoking-induced, dose-related reports of euphoria, and to confirm this relationship using measures of plasma nicotine. In experiment 1, ...
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 ...
