Using 13C-, 15N-, and 18O stable isotope analysis of human bone tissue to identify transhumance, high altitude habitation and reconstruct palaeodiet for the early medieval Alpine population at Volders, Austria [PDF]
, 2007 The analysis of stable isotopes of oxygen from structural carbonate in archaeological human bone samples originating from an early medieval cemetery in the Alpine community of Volders, Austria were used to determine the utilization of higher altitudes ...

FEBS Open Bio, EarlyView.In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Review: Markers and proxies to monitor ruminal function and feed efficiency in young ruminants
Animal, 2021 Developing the rumen’s capacity to utilise recalcitrant and low-value feed resources is important for ruminant production systems. Early-life nutrition and management practices have been shown to influence development of the rumen in young animals with ...

Isotopes in pyrogenic carbon: a review [PDF]
, 2012 Pyrogenic carbon (PC; also known as biochar, charcoal, black carbon and soot) derived from natural and anthropogenic burning plays a major, but poorly quantified, role in the global carbon cycle.

Nitrogen isotopes link mycorrhizal fungi and plants to nitrogen dynamics [PDF]
New Phytologist, 2012 SummaryIn this review, we synthesize field and culture studies of the 15N/14N (expressed as δ15N) of autotrophic plants, mycoheterotrophic plants, parasitic plants, soil, and mycorrhizal fungi to assess the major controls of isotopic patterns. One major control for plants and fungi is the partitioning of nitrogen (N) into either 15N‐depleted chitin ...
