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. [PDF]
J Anim Physiol Anim Nutr (Berl)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 ...

Retinoic Acid Signalling Regulates Zebrafish Tooth Germ Repair Following Injury. [PDF]
Cell ProlifRetinoic acid signalling may regulate the repair processes in a tooth germ injury model using Tg(scpp5:Dendra2‐NTR) zebrafish and the nitroreductase (NTR)/metronidazole (MTZ) system. ABSTRACT Although the role of retinoic acid (RA) signalling in odontogenesis is well established, its involvement in the repair of injured tooth germs remains unclear.
