Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Analysis of energy expenditure and behavioral characteristics in different mouse strains under normal and disease conditions

Animal Models and Experimental Medicine, EarlyView.
Mouse metabolic and behavioral phenotypes are tightly linked to strain, age and disease state, with distinct dysregulation in each disease model, underscoring the need for standardized preclinical experimental conditions. Abstract Background Metabolic and behavioral traits in mice exhibit substantial variability across strains, ages, and disease states,

Review: Update of nutritional requirements of goats for growth and pregnancy in hot environments.

Animal
Goats play an important role in the agricultural business, providing valuable income sources through producing high-quality animal protein. They are widespread livestock for rural households due to their inherent resiliency, adaptability to many ...

Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

The Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

Dietary Mannan‐Rich Fractions Attenuate Weaning Stress in Piglets via Modulating Gut Microbiota and TLR5/NF‐κB Signaling

Animal Research and One Health, EarlyView.
This study aimed to investigate the potential of a mannan‐rich fraction (MRF) as a dietary intervention to alleviate weaning stress in piglets. Our results revealed that MRF could alleviate weaning stress by modulating the gut microbiota and the TLR5/NF‐κB signaling pathway, offering a novel and sustainable alternative to antibiotic use in swine ...

Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

Animal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

Animal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Developmental Characteristics of the Embryonic Liver Tissue and Long‐Term Culture of Primary Hepatocytes in Duck

Animal Research and One Health, EarlyView.
Liver development was investigated at different embryonic ages (EAs). Furthermore, numerous hepatocyte media were formulated and evaluated. These results could elaborate the developmental characteristics of duck liver tissue and determine the most suitable medium for the proliferation and characteristic maintenance of hepatocytes in vitro, which would ...

Key determinants of adaptive strategies of goats to a 2-day nutritional challenge during early lactation.

Animal
Little is known about the key determinants of the physiological adaptations to environmental challenges and how these determinants interact. We evaluated how the response/recovery profiles to a short-term nutritional challenge during early lactation are ...
