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

open access: yesJournal 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

A snake of a different color: physiological color change in Arizona black rattlesnakes [PDF]

open access: yes, 2011
Coloration may serve a variety of behavioral (e.g., crypsis, communication) and physiological (e.g., thermoregulation, protection) functions for terrestrial ectotherms. However, optimal coloration for a given function may vary over environments (spatial

Vimentin Intermediate Filaments: A Paradigm Shift From Static Structure to Dynamic Cytoplasmic Network

open access: yesBioEssays, Volume 48, Issue 3, March 2026.
Vimentin intermediate filaments form a dynamic, motile network that interacts with microfilaments and microtubules. We propose a hybrid transport model to explain vimentin filament dynamics through cytoskeletal crosstalk and organelle‐associated transport.

Hypothyroidism as Prognostic Factor in Cutaneous Melanoma: A 1553‐Patient Single‐Center Study

open access: yesCancer Medicine, Volume 15, Issue 3, March 2026.
ABSTRACT Background Cutaneous melanoma is a rising global health concern and identifying modifiable or associated risk factors remains essential for improving prognostic stratification. Hypothyroidism, affecting approximately 5.1% of the general population in Germany, has been associated with various malignancies. This study investigates the prevalence
