A combined pig model to determine the net absorption of volatile fatty acids in the large intestine under different levels of crude fiber [PDF]
Animal Models and Experimental Medicine, 2023 Background This study aimed to develop a combined model to quantify the net absorption of volatile fatty acids (VFA) in the large intestine (LI) of pigs. Methods Fifteen female growing pigs (Duroc × Large White × Landrace) were ranked by body weight (30 ±

Pharmacokinetics ofp-Aminohippuric Acid and Inulin in Rabbits with Aristolochic Acid Nephropathy [PDF]
Advances in Pharmacological Sciences, 2011 The characteristics of aristolochic acid nephropathy (AAN) are interstitial fibrosis and atrophy of the proximal tubules, but with no change in glomeruli. To investigate the effects of AA on renal functions and the pharmacokinetics (PKs) ofp-aminohippuric acid (PAH) and inulin, New Zealand white rabbits were used in this study.

Betaine increases net portal absorption of volatile fatty acids in Iberian pigs [PDF]
Animal, 2021 Betaine is an osmolyte with the potential to increase volatile fatty acids (VFAs) production and hence improve intestinal health.The present study investigated how betaine affects portal and arterial concentrations and net portal absorption (NPA) of VFA ...

Animal, 2018 In nutrition studies, para-aminohippuric acid (PAH) is a marker frequently used to measure blood flow in pigs, which is essential for estimating portal-drained viscera (PDV) flux of nutrients.

Net Portal Appearance of Amino Acids in Iberian and Landrace Pigs Fed Different Protein Content in the Diet [PDF]
Animals, 2023 Iberian pigs have low rates of muscle protein deposition compared with modern breeds. Differences in net portal appearance (NPA) of amino acids (AA) might partially explain that. NPA of AA was measured in six Iberian and six Landrace gilts (28 kg) fitted

System Identification of the Low-Dose Kinetics of p-Aminohippuric Acid [PDF]
cclm, 1995 The renal clearance of p-aminohippuric acid, due to tubular secretion in addition to glomerular filtration, can only be determined by kinetic experiments. Maximal information can be gained from observed temporal marker concentration profiles by fitting dynamic mathematical models of the processes involved, such as absorption, distribution, and ...

Active Mammary Excretion of N4-Acetylated p-Aminohippuric Acid*) [PDF]
Acta Veterinaria Scandinavica, 1969 Different excretion patterns were observed for p-amino- hippuric acid and its acetylated metabolite in mammary excretion experiments in goats and cows. The excretion of p-aminohippuric acid conformed to passive diffusion of the non-protein bound and un-ionized fraction (Rasmussen 1958, 1966) as described by Miller et al. (1967).
