Selective COX-2 inhibitors are non-steroidal anti-inflammatory drugs which directly target cyclooxygenase-2 (COX-2), an enzyme mainly responsible for induction of inflammation, pyresis and pain. Although commonly used in avian medicine, limited pharmacokinetic (PK) data in domestic and companion birds are available. In this study, PK parameters and...
Identification and validation of extracellular vesicle (EV)-associated biomarkers requires robust isolation and characterization protocols. We assessed the impact of some commonly implemented pre-analytical, analytical and post-analytical variables in EV research. Centrifugal filters with different membrane types and pore sizes are used to reduce l...
Background: We assessed the effects of providing a package of interventions including small-quantity lipid-based nutrient supplements (SQ-LNS) containing 0, 5 or 10 mg zinc and illness treatment to Burkinabe children from 9 to 18 months of age, on biomarkers of zinc, iron and vitamin A status at 18 months and compared with a non-intervention cohort...
Colouration has been considered a cue for mating success in many species; ornaments in males often are related to carotenoid mobilization towards feathers and/or skin and can signal general health and nutrition status. However, there are several factors that can also link with status, such as physiological blood parameters and body condition, but t...
While studying and trying to optimise dialysis clearances of protein-bound uraemic toxins (PBUTs), the percentage protein binding (% PB) may be an important parameter and can be calculated from measured free and total concentrations. Since different parameters may alter this % PB, we investigated whether the ultrafiltration temperature, sample pH, ...
Background: Pharmacokinetic and pharmacodynamic models are used to predict and explore drug infusion schemes and their resulting concentration profiles for clinical application. Our aim was to develop a pharmacokinetic-pharmacodynamic model for remifentanil that is accurate in patients with a wide range of age and weight. Methods: Remifentanil phar...
In this paper, we consider the asymptotic behaviour of solitons and double layers. By using the Sagdeev pseudopotential formalism, a Taylor series expansion is used to derive the asymptotic behaviour. For solitons and supersolitons that propagate faster than the acoustic speed, an exponential decay rate is derived. In contrast, for acoustic speed s...
High velocity impacts of micrometeoroids and debris are proven causes of solar arrays power loss. Many studies have been carried out in this domain with relatively large size particles, in the range of 1mm, causing obviously large damages, but with a small probability of occurrence. This paper deals with the occurrence of secondary arcing triggered...
Introduction: The neonatal population remains one of the populations in which appropriate dosing regimens are still lacking, resulting in a large off-label or unlicensed use. Clinical research in these small infants remains a challenge, which sparks the need for modeling and simulation as an additional tool for neonatal drug research. Methods: The ...
The mobile phase additive (DMSO) has been described as a useful tool to enhance electrospray ionization (ESI) of peptides and proteins. So far, this technique has mainly been used in proteomic/peptide research, and its applicability in a routine clinical laboratory setting (i.e., doping control analysis) has not been described yet. This work provid...
