When considering contaminated site ecology and ecological risk assessment a key question is whether organisms that appear unaffected by accumulation of contaminants are tolerant or resistant to those contaminants. A population of Dendrodrilus rubidus Savigny earthworms from the Coniston Copper Mines, an area of former Cu mining, exhibit increased tolerance(More)
Amblyopia--the commonest vision abnormality of childhood--is characterized by a loss of visual acuity usually of one eye only. Treatment aims to promote function of the amblyopic eye and does this by restricting, usually through occlusion, the competitive advantage of the fellow eye.

In this study the use of collagen-binding assay, recently recommended by the European Pharmacopoeia for the characterization of Factor VIII/von Willebrand Factor (FVIII/vWF) concentrates was investigated. The collagen-binding assay was optimized to decrease reagent variability and, to allow for interlaboratory comparison, standardized against the third WHO(More)
OBJECTIVES We have developed and optimised a new flow-cytometric method for the measurement of the Fc function of intravenous immunoglobulin (IVIg) preparations, which is important in predicting the effector function of immunoglobulin (Ig) in such preparations. MATERIALS AND METHODS Ig was bound to a monocytic cell line, THP-1 with Fc gammaRI and Fc(More)
