Sea Lions Develop Human-like Vernix Caseosa Delivering Branched Fats and Squalene to the GI Tract

Dong Hao Wang, Rinat Rivka Ran‐Ressler, Judy St. Leger, Erika Nilson et autres

Vernix caseosa, the white waxy coating found on newborn human skin, is thought to be a uniquely human substance. Its signature characteristic is exceptional richness in saturated branched chain fatty acids (BCFA) and squalene. Vernix particles sloughed from the skin suspended in …

Vitamin A Deficiency and Hepatic Retinol Levels in Sea Otters, Enhydra lutris

Judy St. Leger, Alison L. Righton, Erika Nilson, Andrea J. Fascetti et autres

Vitamin A deficiency has rarely been reported in captive or free-ranging wildlife species. Necropsy findings in two captively housed southern sea otters (Enhydra lutris nereis) included irregular thickening of the calvaria characterized by diffuse hyperostoses on the internal surface. One animal also …

Hypoxic pulmonary vasodilation: a paradigm shift with a hydrogen sulfide mechanism

Kenneth Ray Olson, Nathan L. Whitfield, Shawn E. Bearden, Judy St. Leger et autres

Hypoxic pulmonary vasoconstriction (HVC), an assumed ubiquitous response of mammalian pulmonary arteries (PA), matches regional ventilation to perfusion via an unknown oxygen sensing mechanism. Global pulmonary hypoxia often produces pulmonary hypertension (PH) but PH is not observed in diving mammals where profound …

Hypoxic pulmonary vasodilation: a paradigm shift with a hydrogen sulfide mechanism

Kenneth Ray Olson, Nathan L. Whitfield, Shawn E. Bearden, Judy St. Leger et autres

Hypoxic pulmonary vasoconstriction (HVC), an intrinsic and assumed ubiquitous response of mammalian pulmonary blood vessels, matches regional ventilation to perfusion via an unknown O(2)-sensing mechanism. Global pulmonary hypoxia experienced by individuals suffering from chronic obstructive pulmonary disease or numerous hypoventilation syndromes, including …
