Midazolam (MDZ) is metabolized in human liver microsomes by the cytochrome P450 (CYP) 3A subfamily to 1'-hydroxy (1'-OH) and 4-hydroxy (4-OH) metabolites. MDZ is metabolized in the rat primarily to 4-OH MDZ, 1'-OH MDZ, and 1',4-dihydroxy (1',4-diOH) MDZ. The kinetics of 4-OH and 1'-OH metabolite formation were determined using hepatic microsomes from(More)
1. A high throughput screening (HTS) method for the evaluation of the seven major human hepatic CYP isoform activities was developed on a 96-well format, with automation. The method utilized pooled human liver microsomes and seven probe substrates, generic conditions for incubation, reaction termination and metabolite extraction with solid phase extraction(More)
BACKGROUND Effective influenza surveillance requires new methods capable of rapid and inexpensive genomic analysis of evolving viral species for pandemic preparedness, to understand the evolution of circulating viral species, and for vaccine strain selection. We have developed one such approach based on previously described broad-range reverse transcription(More)
Rapid intraoperative examination of tissues for fungi is important for the surgical control of infection. Staining of frozen or paraffin-embedded tissues with calcofluor white (CFW) is a rapid nonspecific method for the identification of fungal infection. When viewed with a fluorescence microscope, fungal elements stained with CFW are sharply delineated(More)
DNA from the cultivated mushroom, Agaricus bisporus, was cloned into the bacteriophage lambda vector EMBL3 creating a partial genomic library. Ten random clones from the library were used to probe for restriction fragment length polymorphisms (RFLPs). Six of the ten probes detected polymorphisms and were used to demonstrate variation in wild and cultivated(More)
Background AZD3514 is a first-in-class, orally bio-available, androgen-dependent and -independent androgen receptor inhibitor and selective androgen-receptor down-regulator (SARD). Methods In study 1 and 2, castration-resistant prostate cancer (CRPC) patients (pts) were initially recruited into a once daily (QD) oral schedule (A). In study 1,(More)
BACKGROUND & OBJECTIVES There is paucity of information on vaginal and rectal colonization with multiple serotypes of group B streptococci (GBS). As part of an ongoing cohort study evaluating the natural history of vaginal and rectal colonization by GBS, the colonization with multiple serotypes was studied in 102 non-pregnant women aged 18-30 yr. METHODS(More)
A recent seroprevalence study of newborns indicates that one in 62 children born in New York City has antibodies to the human immunodeficiency virus (HIV). The distribution of incubation periods for paediatric patients is needed to estimate future AIDS case loads from these seroprevalence data. Current estimates of incubation periods for paediatric patients(More)
BACKGROUND Chronic hepatitis C infection is the leading cause of hepatocellular carcinoma (HCC), a highly lethal malignancy with rapidly increasing prevalence in the United States. Little is known about genetic variations and HCC risk. This study aimed to determine if genetic variation in Wnt signaling pathway genes are associated with advanced hepatic(More)
Heat-inactivated normal human serum produces iron-reversible bacteriostasis of a number of microorganisms. This inhibitory effect was abolished by adsorption of serum with ultraviolet-killed cells of species that produce the siderophore enterochelin. Bacteriostasis also was alleviated by adsorption of serum with 2,3-dihydroxy-N-benzoyl-L-serine, a(More)
