JC and BK human polyomaviruses (family Polyomaviridae) may cause severe neurological or urinary tract pathologies in immunocompromised hosts. In the present study, we evaluated a new commercially available PCR and microplate colorimetric hybridization assay for the standardized differential detection of JC virus (JCV) and BK virus (BKV) genomes in clinical samples. This JC/BK Consensus test was...
1. Normetanephrine was measured in small samples of plasma and urine of hypertensive patients and normal volunteers (age 20-60 years) by a specific radioenzymatic assay with bovine adrenal phenylethanolamine N-methyltransferase and tritiated S-adenosylmethionine. 2. Noradrenaline was measured simultaneously in plasma and urine. 3. Plasma normetanephrine and noradrenaline concentrations varied i...
Background and Aims: Group B streptococcus (GBS) may cause neonatal infection during and or after the delivery, and is the leading cause of sepsis, bacteremia, pneumonia and meningitis. The virulence factors are carried by both capsule and surface proteins by which serotypes and genotypes are determined. However, some genotypes are believed to be related in severity of neonatal diseases, theref...
Since collection of 24 h urine samples is very time consuming and difficult to obtain, epidemiological studies typically only obtain spot urine samples. The aim of the present study was to evaluate whether flavonoids and enterolactone in overnight urine could substitute flavonoids and enterolactone in 24 h urine as an alternative and more feasible biomarker of fruit, vegetable and beverage inta...
Anthocyanins are polyphenols responsible for most red to purple colors in plants. Human consumption of these pigments is increasing because of their potential health benefits and use as natural colorants. With more than 600 different anthocyanins found in nature, the impact of chemical structure on their absorption and metabolism needs to be investigated. Urine and plasma samples were collected...
This study determined the mass balance and pharmacokinetics of edoxaban in humans after oral administration of [¹⁴C]edoxaban. After oral administration of 60 mg (as active moiety) of [¹⁴C]edoxaban to six healthy male subjects, serial blood/plasma and urinary and fecal samples were collected for up to 168 h postdose. All samples were analyzed for total radioactivity by liquid scintillation count...
SCOPE Numerous studies feeding anthocyanin-rich foods report limited bioavailability of the parent anthocyanins. The present study explores the identity and concentration of the phenolic metabolites of anthocyanins in humans. METHODS AND RESULTS Anthocyanin metabolites were quantified in samples collected from a previously conducted 12-wk elderberry intervention study in healthy post-menopaus...
Simple and sensitive liquid chromatography (LC) methods with fluorescence (FL) detection for the determination of bendamustine (BM) in human plasma and urine were developed and validated. The procedure of BM extraction from a plasma sample involved solid-phase extraction with a C18 SPE column, while liquid-liquid extraction with dichloromethane was applied for a urine sample. In both methods, c...
