We present the development and optimization of an analytical method based on Laser Ablation–Inductively Coupled Plasma–Mass Spectrometry (LA-ICP-MS) for analysis multivitamin dietary supplements. Samples were ground mixed with a cellulose powder containing internal standard elements; resulting was pressed into pellets. Two calibration strategies compared: (1) using increasing mass fractions for...

BACKGROUND The aims of this study were to compare various genotypic scoring systems commonly used to predict virological outcome to etravirine, and examine their concordance with etravirine phenotypic susceptibility. METHODS Six etravirine genotypic scoring systems were assessed: Tibotec 2010 (based on 20 mutations; TBT 20), Monogram, Stanford HIVdb, ANRS, Rega (based on 37, 30, 27 and 49 mut...

Previous work has identified the positive effects of the acute administration of a multivitamin-guaraná preparation during an effortful executive/working memory task. Here, we aimed to differentiate the effects of multivitamins with and without guaraná and to examine the neural substrates of such effects using functional magnetic resonance imaging (fMRI). Following a double-blind, placebo-contr...

This study was designed to evaluate the effect of routine intake multivitamin minerals supplements (MVMS) as children’s drugs on serum marker enzymes, mineral components and their general wellness. Blood samples were obtained from 40 children within age range 1 5 years old at Ekiti State Teaching Hospital, Ado Ekiti. Serum level Potassium (K), Calcium (Ca), Zinc (Zn), Magnesium (Mg), Iron (Fe),...

In this cohort study, the authors evaluated how supplemental use of multivitamins, vitamin C, and vitamin E over a 10-year period was related to 5-year total mortality, cancer mortality, and cardiovascular disease (CVD) mortality. Participants (n = 77,719) were Washington State residents aged 50-76 years who completed a mailed self-administered questionnaire in 2000-2002. Adjusted hazard ratios...

The authors examined use of individual supplements of vitamins A, C, and E only and multivitamins in relation to risk of non-Hodgkin's lymphoma in prospective cohorts of 88,410 women in the Nurses' Health Study (1980-1996), with 261 incident cases during 16 years of follow-up, and of 47,336 men in the Health Professionals Follow-Up Study (1986-1996), with 111 incident cases during 10 years of f...
