The study investigated the effect of dietary inclusion of high amylose cornstarch (HA-starch) on cecal microbiota composition and volatile fatty acid (VFA) concentrations in weanling pigs fed high levels of cold-pressed canola cake (CPCC). Weaned pigs (240 mixed sex; 7.1 ± 1.

It is urgent for patients with chronic kidney disease (CKD) to develop a robust and facile therapy for effective control of serum phosphate and reasonable regulation of gut microbiota, which are aiming to prevent cardiovascular calcification and reduce cardiovascular complications. Here, bioinspired by intestinal microstructures, we developed biomimetic wrinkled prebiotic-containing microspheres with enhanced intestinal retention and absorption for reducing hyperphosphatemia and vascular calcification of CKD model rats. The resultant CSM@5 microspheres exhibited favorable phosphate binding capacity in vitro and could effectively reduce serum concentration of phosphorous in vivo.

Elasmobranchs are commonly carnivores and are important in energy transfer across marine ecosystems. Despite this, relatively few studies have examined the physiological underpinnings of nutrient acquisition in these animals. Here, we investigated the mechanisms of uptake at the spiral valve intestine for two representative amino acids (-alanine, -leucine) and one representative fatty acid (oleic acid), each common to the diet of a carnivore, the Pacific spiny dogfish (Squalus suckleyi).

Although long-term high dietary sodium consumption often aggravates hypertension and bone loss, sodium in the intestinal lumen has been known to promote absorption of nutrients and other ions, e.g., glucose and calcium.

The contribution of the gut to the ingestion, production, absorption, and excretion of the extra ammonia and urea-N associated with feeding ("exogenous" fraction) has received limited prior attention. Analysis of commercial pellet food revealed appreciable concentrations of ammonia and urea-N. Long term satiation-feeding increased whole trout ammonia and urea-N excretion rates by 2.
