Resilient Biophysical Phenotype of Memory CD4+ T Cells in Long‐Lived Mice

Immunology, EarlyView.
Aging is associated with increased stiffness and reduced migratory capacity of memory CD4+ T cells; however, these biophysical declines do not persist in exceptionally long‐lived mice. Instead, long‐lived individuals preserve T cell mechanics, migration and intracellular architecture, supporting mechanical resilience as a hallmark of successful immune ...

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon (Salmo salar L.)

Journal of Fish Diseases, EarlyView.
ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a
