In light of recent developments of the onboard ballast water treatment, WMR has developed a new protocol for the assessment of ecotoxicological effects and aims to use it as a standardised test. This study looks into the validation of this short-chronic ELS fish toxicity test, by use of the embryonic …

It can be concluded that the HBM4EU serum sample preparation method is suitable for Effect-Directed Analysis. The method allows a recovery of all bioactive compounds of interest from serum in the EDA products, with little loss of compounds: bioassay spectra and chromatograms. Nevertheless, the HBM4EU …

Perfluoro alkyl substances (PFAS) are substances in which contain multiple fluorine atoms. The fluorine atoms are bound to, often, long carbon chains. PFAS are able to repel dirt and water, due to the large amount of fluorine atoms in the molecules. PFAS are also chemically and thermally stable. Many …

Background: The heat shock protein (HSP) inducer, geranylgeranylacetone (GGA), was previously found to protect against atrial fibrillation (AF) remodeling in experimental model systems. Clinical application of GGA in AF is limited, due to low systemic concentrations owing to the hydrophobic character …

In the recent past, the use of resins in modern tread compounds has increased considerably, in order to further improve tire properties. Based on the experience with silica-silane filler system, which led to a different network structure and a significantly changed devulcanization behavior, the influence …

Tires are an important vehicle component, as car handling, safety and fuel economy depend for a major part on the tire composition and construction. As a consequence, tires are improved continuously. The most prominent improvement in the recent past was the use of a silica-silane filler system in passenger …

Using the reversed phase high performance liquid chromatography with diode-array and massspectrometric (in ESI mode) detection, a composition of Catharanthus roseum petals was established. After the acid hydrolysis, all five anthocyanidins were found to be different comparing to the ordinary anthocyanidins …

Coastal tourism and recreation are one of the most rapidly growing fields worldwide and people spend more time outdoors. Skin protection is, in this respect, important to prevent severe skin damage and skin aging. The past decades the awareness and the importance of skin protection against long time …

This paper describes the development of one solid phase extraction method for a wide group of pharmaceutical and industrial compounds in wastewater that is analyzed with two LC-MS/MS methods.

Relatively new products which are mostly marketed by online communities and online influencers as healthy or having therapeutic effects are being sold across Europe and United States, online or local drugstores, without ensuring that these products go through any quality analysis. This introduces a threat …
