Despite being known for nearly two centuries, new specimens of the derived non-pterodactyloid pterosaur Rhamphorhynchus continue to be discovered and reveal new information about their anatomy and palaeobiology. Here we describe a specimen held in the collections of the Royal Tyrrell Museum of Palaeontology, Alberta, Canada that shows both preservation and impressions of soft tissues, and also preserves material interpreted as stomach contents of vertebrate remains and, uniquely, a putative coprolite. The specimen also preserves additional evidence for fibers in the uropatagium.

Background: PAPP is widely used in Australia as a potent vertebrate bait, with potential for off-target ingestion and poisoning in domestic dogs. Whilst toxicosis and resulting methaemoglobinaemia is anecdotally known to occur, this is the first description in the literature. This study reports thirteen clinical cases of suspected Para-aminopropiophenone (PAPP) toxicity in dogs, with the aim of describing clinical presentation and current management of toxicosis in this species.

Seaweed biomass is globally underutilized as a source of proteins despite its nutritional potential, with much of its use focused on hydrocolloid extraction. This study evaluated the nutritional quality and digestibility of protein and amino acids from two brown seaweeds ( spp. and ), one green seaweed ( spp.

This study aimed to evaluate the effect of early weaning (EW) on the growth performance, gastrointestinal development, serum parameters, and metabolomics of Hu sheep lambs. Twenty-four male Hu lambs were initially ewe-reared. A total of 12 lambs were weaned at 30 d of age (D30) as the EW group, and the remaining 12 lambs were weaned at 45 d of age (D45) as the control (CON) group.

Background And Aims: Digestion of gluten-derived immunogenic peptides along the gastrointestinal tract (GIT) is not well established. This study aimed to map the digestion of gluten-derived immunogenic peptides along the GIT using the growing pig as a human adult model, and actinidin as a model exogenous protease.
Methods: Entire male pigs 9 weeks of age (n=54, 19.

This study aimed to produce protein hydrolysates from superworm (Zophobas morio) flour using the enzymes alcalase (HA), protamex (HP), or flavourzyme (HF), and to characterize their nutritional composition, techno-functional properties, bioactive capacity, and bioaccessibility index. The enzymatic process increased the total amino acid and crude protein contents of the hydrolysates by approximately 36 % and 46 %, respectively, generating better foaming capacity, oil retention, and emulsification capacity, when compared to raw flour. Although 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical capture was similar between the hydrolysates, HA (1479,66 μM FeSO/g) and HP (1514,66 μM FeSO/g) showed greater antimicrobial and iron reducing power (FRAP) activity, while HF has a higher scavenging efficiency for the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical (27.
