Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

open access: yesJournal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Adaptation to extreme environments: A review of Antarctic fish physiology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

How AFM has contributed to the understanding of bacterial cell wall peptidoglycan structure

open access: yesJournal of Microscopy, EarlyView.
Abstract The bacterial cell wall is an essential exoskeleton that plays a major role in conferring cell shape, serving as the primary stress‐bearing layer, resisting the several atmospheres turgor pressure created by the imbalance in molecular concentrations between the cell interior and the surrounding medium, while also playing a central role in host‐

Architecture and Evolution of Prokaryotic Multicellularity: Common Patterns and Diversity

open access: yesMolecular Microbiology, EarlyView.
Prokaryotes form diverse multicellular structures, like biofilms, filaments, and aggregates, comprising hallmark traits such as adhesion, communication, differentiation, and programmed cell death. This review explores how these forms develop, function, and evolve in response to environmental cues.

Disentangling atmospheric and soil drought: a new stand‐level manipulation approach for mature forests

open access: yesNew Phytologist, EarlyView.
Design of the VPDrought experiment in a Scots pine (Pinus sylvestris) forest at the Pfynwald research platform. Summary Atmospheric and soil drought are major, yet typically confounded, drivers of tree stress. Rising vapor pressure deficit (VPD) may impair forest function independently of soil moisture decline, yet stand‐scale experimental separation ...

Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

open access: yesMolecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.
