Digoxin net secretory transport in bronchial epithelial cell layers is not exclusively mediated by P-glycoprotein/MDR1
(2014-01)The impact of P-glycoprotein (MDR1, ABCB1) on drug disposition in the lungs as well as its presence and activity in in vitro respiratory drug absorption models remain controversial to date. Hence, we characterised MDR1 ... -
Dilemmas in the reliable estimation of the in-vitro cell viability in magnetic nanoparticle engineering : which tests and what protocols?
(2012)Magnetic nanoparticles [MNPs] made from iron oxides have many applications in biomedicine. Full understanding of the interactions between MNPs and mammalian cells is a critical issue for their applications. In this study, ... -
Dimensions and Determinants of Financialisation : Comparing OECD Countries since 1997
(2019-10-10)The financialisation literature has grown over the past decades. Despite a generally accepted definition, financialisation has been used to describe different phenomena. We distinguish between financialisation of non-financial ... -

Dimethicone barrier cream prevents infection of human skin by Schistosome cercariae : Evidence from Franz cell studies
(2002-04)One approach to the prevention of schistosomiasis is the use of topical formulations to inhibit cercalial penetration of skin. A number of formulations containing either cercaricidal ingredients or components designed to ... -
Diminished 11 Beta-Hydroxysteroid Dehydrogenase Type 2 Activity Is Associated With Decreased Weight and Weight Gain Across the First Year of Life.
(2014-05-01)Objective: We have hypothesized that changes in GC metabolism leading to increased availability may impair growth. Design: This was a prospective, longitudinal study with clinical measurements and 24-hour urinary steroid ... -
Dining out with Coeliac Disease : An Analysis of online Message Board Postings on the Social Implications and the Challenges to Live A Normal Life
(2014-02-22)Strict adherence to a gluten free diet is the only treatment for coeliac disease. Over the past two decades, there has been a societal shift into less home cooking and eating at restaurants has become an important means ... -

Diploma to degree 1976 to 1993
(2009)The debate on degree education for radiographers began in earnest in the mid-1970s. Initially the debate hinged around whether a degree education was necessary for radiographers. One argument was that it was felt that a ... -
Dips and eclipses in the X-ray binary Swift J1858.6-0814 observed with NICER
(2021-06-01)We present the discovery of eclipses in the X-ray light curves of the X-ray binary Swift J1858.6-0814. From these, we find an orbital period of $P=76841.3_{-1.4}^{+1.3}$ s ($\approx21.3$ hours) and an eclipse duration of ... -
A direct calibration of the IRX-β relation in Lyman-break Galaxies at z=3-5
(2018-10)We use a sample of 4209 Lyman-break galaxies (LBGs) at z ≃ 3, 4, and 5 in the UKIRT Infrared Deep Sky Survey Ultra Deep Survey field to investigate the relationship between the observed slope of the stellar continuum ... -
Direct effects of 3,4-methylenedioxymethamphetamine (MDMA) on serotonin or dopamine release and uptake in the caudate putamen, nucleus accumbens, substantia nigra pars reticulate, and the dorsal raphe nucleus slices
(2000-06-15)We examined the effects of pressure ejected 3,4-methylenedioxymethamphetamine (MDMA) from a micropipette on direct chemically stimulated release, and on electrically stimulated serotonin (5-HT) or dopamine (DA) release in ... -
Direct Evidence for Termination of Obscured Star Formation by Relatively Driven Outflows in Reddened QSOs
(2012-02)We present optical to far-infrared photometry of 31 reddened QSOs that show evidence for radiatively driven outflows originating from active galactic nuclei (AGNs) in their rest-frame UV spectra. We use these data to study ... -
Direct imaging of long period radial velocity targets with NICI
(2013-06-30)We are finally entering an era where radial velocity and direct imaging parameter spaces are starting to overlap. Radial velocity measurements provide us with a minimum mass for an orbiting companion (the mass as a function ... -
Direct involvement, partnership and setting: a study in bounded diversity
(2013-04-03)This paper brings a comparative aspect to the analysis of direct involvement as the foundation for partnership. It considers how various forms of direct involvement can represent components of a broader partnership paradigm ... -
Direct Ionization of Solid-Phase Microextraction Fibers for Quantitative Drug Bionalysis : From Peripheral Circulation to Mass Spectrometry Detection
(2015-01-06)A novel approach is described for the quantitative bioanalysis of drugs in blood samples by ionization of the analytes collected on solid-phase microextraction (SPME) fibers by mass spectrometry (MS). The technique combines ... -
Direct measurement of gain recovery in a saturated Nd-glass amplifier
(1978)The temporal dependence of the gain recovery in a Nd-silicate glass amplifier has been directly observed after the passage of a short intense saturating laser pulse. The gain recovery time constant measured for ED-2 glass ...
