The Long-Term Effects of Developmental Hypoxia on Cardiac Mitochondrial Function in Snapping Turtles (2021)
Journal Article

It is well established that adult vertebrates acclimatizing to hypoxic environments undergo mitochondrial remodeling to enhance oxygen delivery, maintain ATP, and limit oxidative stress. However, many vertebrates also encounter oxygen deprivation dur... Read More about The Long-Term Effects of Developmental Hypoxia on Cardiac Mitochondrial Function in Snapping Turtles.

Turning turtle: scaling relationships and self-righting ability in Chelydra serpentina (2021)
Journal Article

Testudines are susceptible to inversion and self-righting using their necks, limbs or both, to generate enough mechanical force to flip over. We investigated how shell morphology, neck length and self-righting biomechanics scale with body mass during...

A marine teleost, Opsanus beta, compensates acidosis in hypersaline water by H+ excretion or reduced HCO3− excretion rather than HCO3− uptake (2020)
Journal Article

Increases in ambient salinity demand parallel increases in intestinal base secretion for maintenance of osmoregulatory status, which is likely the cause of a transient acidosis following transfer of euryhaline fish from freshwater to seawater. It was... Read More about A marine teleost, Opsanus beta, compensates acidosis in hypersaline water by H+ excretion or reduced HCO3− excretion rather than HCO3− uptake.

Is aquaporin‐3 involved in water‐permeability changes in the killifish during hypoxia and normoxic recovery, in freshwater or seawater? (2020)
Journal Article

Aquaporins are the predominant water-transporting proteins in vertebrates, but only a handful of studies have investigated aquaporin function in fish, particularly in mediating water permeability during salinity challenges. Even less is known about a... Read More about Is aquaporin‐3 involved in water‐permeability changes in the killifish during hypoxia and normoxic recovery, in freshwater or seawater?.

Steroid Concentrations in Plasma, Whole Blood and Brain: Effects of Saline Perfusion to Remove Blood Contamination from Brain (2010)
Journal Article

The brain and other organs locally synthesize steroids. Local synthesis is suggested when steroid levels are higher in tissue than in the circulation. However, measurement of both circulating and tissue steroid levels are subject to methodological co...
