Chemically and pharmacologically unrelated molecules release histamine in humans to produce both cutaneous and systemic responses. It has been suggested that molecular changes in the new benzylisoquinoline-derived muscle relaxant, atracurium, make it less likely to cause histamine release. We therefore injected volunteers intradermally with equimolar(More)
BACKGROUND Sepsis and death subsequent to the transfusion of blood containing Yersinia enterocolitica is an increasing problem. The organisms probably originate from bacteremia in the donor and can subsequently multiply at low temperature. STUDY DESIGN AND METHODS Reported here are experiments with a strain of Y. enterocolitica associated with a case of(More)
AIMS To examine how delayed refrigeration of blood affects the growth of Pseudomonas fluorescens, one of the two most important causes of sepsis resulting from transfusion of contaminated blood. METHODS Two donations of whole blood were each divided into three aliquots and inoculated with 5-10 cfu/ml of a P fluorescens strain from a case of transfusion(More)
Localized magnetic hyperthermia as a treatment modality for cancer has generated renewed interest, particularly if it can be targeted to the tumor site. We examined whether tumor-tropic neural progenitor cells (NPCs) could be utilized as cell delivery vehicles for achieving preferential accumulation of core/shell iron/iron oxide magnetic nanoparticles(More)
Responses were recorded from muscle spindles in the extensor digitorum longus muscle of the freshwater tortoise Chelodina longicollis. Most spindles showed no resting discharge unless the muscle was stretched up to a millimetre beyond the minimum body length. The firing rate then increased by 2-5 imp./sec/mm extension. All spindles were relatively(More)
