Abundance, distribution and characteristics of microplastics in the North and South Atlantic Ocean.

Microplastics are both pervasive in the marine environment and highly detrimental to it. In this study, we investigate the abundance, distribution, and characteristics of microplastics in surface waters on a transect spanning 6 major ocean current regions in the Atlantic Ocean from Scheveningen (the Netherlands) to Montevideo (Uruguay). 50 surface trawls were completed with a manta net (mesh 500 μm, cod 333 μm) and particles were analyzed in the laboratory including polymer type identification with ATR-FTIR spectroscopy.

Forensic necropsies of cattle: a study of Danish cases from 2010 to 2021 and a guideline for forensic examination of cattle.

Forensic post-mortem examinations of animals are carried out on suspicion of violation of European and national legislation. In Denmark, and probably also in other countries with large-scale cattle production, cattle are regularly submitted for forensic assessment. Unfortunately, only few studies of forensic pathology in cattle are available.

Noninvasive assessment of pulse-wave velocity and flow-mediated vasodilation in anesthetized Göttingen minipigs.

Few methods for noninvasive assessment of arterial stiffness and endothelial dysfunction in porcine models are available. The aim of this study was to evaluate methods for assessment of arterial stiffness and endothelial dysfunction in anesthetized Göttingen minipigs. Pulse-wave velocity (PWV) was assessed in male Göttingen minipigs (n = 8; age approximately 60 wk) by using applanation tonometry of the carotid and femoral arteries.
