AIM A longer duration of untreated psychosis (DUP) is associated with greater morbidity in the early course of schizophrenia. This formative, hypothesis-generating study explored the effects of stigma, as perceived by family members, on DUP. METHODS Qualitative interviews were conducted with 12 African American family members directly involved in… (More)
AIM This study used a qualitative research methodology to explore common themes pertaining to the period of untreated psychosis before treatment initiation in hospitalized, urban, African American, first-episode psychosis patients. METHODS Twelve family members of 10 patients were interviewed at length to gather detailed narrative accounts of factors… (More)
We evaluated the variability in the amount of protein adsorbed onto the surface of individual wells of an assortment of microtitre plates by use of procedures involving enzyme-protein conjugates. Coefficients of variation in adsorbed protein ranged from 5.2 to 29.5%. Microtitre plates show a distinct "edge effect"; wells at the edges of a plate adsorb more… (More)
The various types of chemiluminescent and bioluminescent reactions are described. Applications of luminescence in the analysis of substancs of clinical interest are surveyed. The advantages, disadvantages, and prospects for luminescent assays are discussed.
OBJECTIVE Duration of untreated psychosis (DUP) has been associated with poor early course outcomes of nonaffective psychotic disorders; however, less is known about predictors of DUP. This study examined patient-level predictors of DUP and clinical correlates of both DUP and duration of untreated illness (DUI), both of which have been implicated as… (More)
Thermal studies of various types of microtitre plate have shown that wells at the edges of a plate have different thermal characteristics from those in the centre. This may contribute to the 'edge effect' observed when such plates are used as solid supports for protein immunobilisation in immunoassays.
Effective internal quality control and external quality assessment of high-density lipoprotein cholesterol assay is made difficult by analyte instability, and the suitability of quality-control sera for this purpose has not been studied. We have therefore investigated the properties of 25 different control sera from 15 suppliers by estimating within-batch… (More)
