Nitrogen isotope analysis of ammonium and glycine [PDF]
, 2005 Stable isotope techniques can be used as a tool in nitrogen cycling studies of different ecosystems. The studies are based on measurement of the heavy (15N)- to- light (14N) isotopic ratios of nitrogen in different biospheric pools.

The scent of death: A case study for volatile markers of decomposition on a concrete floor
Journal of Forensic Sciences, EarlyView.Abstract Volatile organic compounds (VOCs) released during human decomposition are chemically diverse and can provide forensic evidence indicating the prior presence of a corpse. In July 2023, the Michigan City Police Department received a report from an individual claiming to have murdered his roommate and stored the body in a basement cellar for 57 ...

Influence of oxidized oils on digestibility of caseins in O/W emulsions [PDF]
, 2018 The impact of lipid oxidation on protein modifications in emulsions and the consequences on protein digestibility remains unclear. In this study, this impact is evaluated in casein (6 mg mL(-1)) based emulsions containing oxidized soybean or fish oil (3%)

Ecological Entomology, EarlyView.Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Solid-phase microextraction for analysis of mould cheese aroma
Czech Journal of Food Sciences, 2006 Solid-phase microextraction coupled with gas chromatography was used for the analysis of volatile aroma compounds in Niva cheese. The extraction conditions were very mild, which minimises thermal, mechanical, or chemical modification of the sample; the ...

An Easy Method to Sample Headspace Pheromones in the Field
Ethology, EarlyView.Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Plant Biotechnology Journal, EarlyView.ABSTRACT Plant glandular trichomes (GTs) are characterised by their ability to synthesise and store abundant secondary metabolites of significant biological importance. The medicinal plant Artemisia argyi exhibits a dense covering of GTs, yet the precise metabolic compositions and the developmental molecular dynamics of A.
