Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

open access: yesThe Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

open access: yesAnimal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Chicken Pulmonary MicroRNAs Targeting the PB2 (Segment 1) of Avian Influenza Virus

open access: yesAnimal Research and One Health, EarlyView.
The PB2 segment of H5N1 is essential for replication and host adaptation. We screened 200 miRNAs and identified five (gga‐miR‐17‐3p, gga‐miR‐29a‐5p, gga‐miR‐1718, gga‐miR‐16c‐5p, and gga‐miR‐1744‐5p) using thermodynamic stability of heteroduplex, seed sequence complementarity, conservation, and accessibility, offering insights into host antiviral ...
