Anna Flis et al.
Pharmacological reports : PR, 67(1), 1-8 (2015-01-07)
Human prostate cancer (hPCa) is the most commonly diagnosed cancer in elderly men and is the second leading cause of male cancer death. Data from epidemiological, eco-environmental, nutritional prevention and clinical trials suggest that selenium Se(IV) can prevent prostate cancer....
Lore Geldof et al.
Biomedical chromatography : BMC, 28(7), 974-985 (2014-02-06)
Anti-doping laboratories need to be aware of evolutions on the steroid market and elucidate steroid metabolism to identify markers of misuse. Owing to ethical considerations, in vivo and in vitro models are preferred to human excretion for nonpharmaceutical grade substances....
Christopher Polonyi et al.
Dalton transactions (Cambridge, England : 2003), 43(31), 11941-11949 (2014-06-27)
The ability of the anticancer active drug cisplatin to exert biological activity through interference with nucleic acid function is well documented. Since kinetics play a key role in determining product distributions in these systems, methods for accurate documentation of reactivity...
Oliver Wahl et al.
Journal of pharmaceutical and biomedical analysis, 102, 100-109 (2014-09-30)
Magnesium supplementation in form of organic magnesium salts is a very popular practice. We examined the enantiomeric purity of "Magnesium aspartate dihydrate" monographed in the European Pharmacopeia. A chiral capillary zone electrophoresis using (2-hydroxypropyl)-β-cyclodextrin coupled to laser induced fluorescence detection...
Raphael Paus et al.
European journal of pharmaceutics and biopharmaceutics : official journal of Arbeitsgemeinschaft fur Pharmazeutische Verfahrenstechnik e.V, 96, 53-64 (2015-07-15)
In this paper, the intrinsic dissolution profiles of naproxen (NAP) at pH values of 1.5 and 3.0 and of trimethoprim (TMP) at pH values of 1.5, 3.0, 5.0, 6.5 and 7.2 were measured. Meanwhile, the dissolution profiles of NAP and...

Materials science & engineering. C, Materials for biological applications, 58, 666-674 (2015-10-20)
Immunosensors based on gold nanoparticles and reduced graphene oxide (AuNPs/rGO)-modified screen-printed electrodes (SPEs) were successfully synthesized using an electrochemical deposition method. The modified SPEs were characterized using a field emission scanning electron microscope (FESEM) and Raman spectroscopy to analyze the...
Susann K J Ludwig et al.
Analytical and bioanalytical chemistry, 406(27), 6857-6866 (2014-06-29)
Current contaminant and residue monitoring throughout the food chain is based on sampling, transport, administration, and analysis in specialized control laboratories. This is a highly inefficient and costly process since typically more than 99% of the samples are found to...
Xiaoning Li et al.
Bioconjugate chemistry, 26(3), 520-528 (2015-02-26)
Subcutaneous delivery is one of the preferred administration routes for therapeutic monoclonal antibodies (mAbs). High antibody dosing requirements and small injection volumes necessitate formulation and delivery of highly concentrated mAb solutions. Such elevated antibody concentrations can lead to undesirable solution...
Sohini Mukherjee et al.
Nature communications, 6, 8467-8467 (2015-10-13)
Creating an artificial functional mimic of the mitochondrial enzyme cytochrome c oxidase (CcO) has been a long-term goal of the scientific community as such a mimic will not only add to our fundamental understanding of how CcO works but may...
Patrizia Iavicoli et al.
Journal of chromatography. A, 1422, 260-269 (2015-10-27)
Asymmetric Flow Field-Flow Fractionation (AF4) combined with multidetector analysis form a promising technique in the field of nanoparticle characterization. This system is able to measure the dimensions and physicochemical properties of nanoparticles with unprecedented accuracy and precision. Here, for the...
E L Menzies et al.
Drug testing and analysis, 6(6), 506-515 (2014-02-28)
The classic approach of controlled volunteer studies to study drug metabolism is difficult or impossible to undertake for novel psychoactive substances (NPS), as there is generally very limited information available to allow appropriate dose finding and safety. A viable and...
M J Hilhorst et al.
Journal of chromatography. B, Analytical technologies in the biomedical and life sciences, 965, 45-53 (2014-07-06)
A liquid chromatography-tandem mass spectrometry method is described for the quantitative determination of artemether (ART) and its metabolite dihydroartimisinin (DHA) in human plasma samples. Quantitation of ART and DHA in plasma is challenging due to the presence of malaria related...
Anja Täuber et al.
Molecular pharmaceutics, 11(7), 1991-1996 (2014-02-05)
Onychomycosis is a fungal infection mostly induced by dermatophytes such as Trichophyton rubrum. Due to slow nail growth, the treatment takes 3-9 months depending on the nail size and infected area. Hence, high efficacy of the active ingredient without systemic...
M O Besenhard et al.
International journal of pharmaceutics, 475(1-2), 198-207 (2014-08-12)
We present a proof-of-concept study of a continuous coating process of single API crystals in a tubular reactor using coacervation as a microencapsulation technique. Continuous API crystal coating can have several advantages, as in a single step (following crystallization) individual...
