Urea transport proteins were initially proposed to exist in the kidney in the late 1980s when
studies of urea permeability revealed values in excess of those predicted by simple lipid …

While adult zebrafish, Danio rerio, possess ammonia and urea transporters (Rh and UT
proteins, respectively) in a number of tissues, they are most heavily concentrated within the …

A urea transporter protein in the kidney was first proposed in 1987. The first urea transporter
cDNA was cloned in 1993. The SLC14a urea transporter family contains two major …

The following study set out to test the hypothesis that acute treatment with the selective
serotonin reuptake inhibitor, fluoxetine, would result in a rise in circulating 5-HT levels and …

Acute stress may affect metabolism and nitrogen excretion as part of the adaptive response
that allows animals to face adverse environmental changes. In the present paper the acute …

An understudied consequence of coastal urbanization on marine environments is sound
pollution. While underwater anthropogenic sounds are recognized as a threat to aquatic …

Measurable quantities of the selective serotonin reuptake inhibitor (SSRI), fluoxetine, have
been found in surface waters and more recently in the tissues of fish. This highly prescribed …

The nature of ammonia and urea excretion was examined in the Pacific hagfish (Eptatretus
stoutii), which, under resting conditions, excreted similar quantities of nitrogen as either …

The small cichlid fish Alcolapia grahami lives in Lake Magadi, Kenya, one of the most
extreme aquatic environments on Earth (pH~ 10, carbonate alkalinity~ 300 mequiv l− 1). The …
