Effect of Dietary Vitamin A, Breed, and Kidney Function on the Onset of Urinary Vitamin A Excretion and the Vitamin A Transport Complex in Growing Dogs

open access: yesJournal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 813-819, September 2026.
ABSTRACT Vitamin A (retinol and retinyl esters) is present in substantial amounts in the urine of healthy adult dogs, but the mechanisms affecting its excretion are poorly understood. To assess whether the onset of urinary vitamin A excretion is dependent on dietary vitamin A intake, breed, and/or parameters of kidney function, 48 puppies from two ...

Last Tile Added to a Mosaic: Phylogenetic Placement of Enigmatic Freshwater Fish Leucalburnus satunini (Cypriniformes: Leuciscidae) Uncovered

open access: yesZoologica Scripta, Volume 55, Issue 5, Page 718-727, September 2026.
ABSTRACT Subfamily Leuciscinae, the largest freshwater fish group of the western Palearctic region, has been widely studied, including the phylogenetic relationships between its species and genera. However, until now, one genus completely escaped attention in this regard. Even though several works hypothesised about its evolutionary relationships based
