Metabolic constraints and individual variation shape the trade-off between physiological recovery and anti-predator responses in adult sockeye salmon.

Metabolic scope represents the aerobic energy budget available to an organism to perform non-maintenance activities (e.g., escape a predator, recover from a fisheries interaction, compete for a mate).

The influence of water temperature on sockeye salmon heart rate recovery following simulated fisheries interactions.

Selective harvest policies have been implemented in North America to enhance the conservation of Pacific salmon ( spp.) stocks, which has led to an increase in the capture and release of fish by all fishing sectors. Despite the immediate survival benefits, catch-and-release results in capture stress, particularly at high water temperatures, and this can result in delayed post-release mortality minutes to days later.

An experimental test of in-season homing mechanisms used by nest-guarding male Largemouth Bass following displacement.

Through manipulations of sensory functions, researchers have evaluated the various mechanisms by which migratory fish, particularly in lotic systems, locate natal spawning grounds. Comparatively less work has occurred on the ways by which fish in lentic systems locate spawning sites, and more specifically, the ways by which displaced fish in these systems locate their broods post spawning. The primary goal of this research was to determine the sensory mechanisms used by nesting, male Largemouth Bass to navigate back to their brood following displacement.

The effect of simvastatin treatment on endothelial cell response to shear stress and tumor necrosis factor alpha stimulation.

Background: Statin drugs are one of the most commonly prescribed pharmaceuticals by physicians. By blocking the rate-limiting step in the cholesterol biosynthesis pathway, statins inhibit cholesterol synthesis, which benefits patient health. However, since many other important cellular processes are regulated within this pathway, they may also be influenced by statin therapy.

Statin therapy influences endothelial cell morphology and F-actin cytoskeleton structure when exposed to static and laminar shear stress conditions.

Aims: To determine how statin drugs (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) affect endothelial cell (EC) shape and F-actin cytoskeleton arrangement in the presence of physiologically relevant wall shear stress (WSS) of 12.5dyn/cm(2).

Main Methods: Human abdominal aortic endothelial cells (HAAECs) were cultured to a confluent monolayer within three dimensional tissue culture models and presheared for 6h at 12.
