The optimal utilization of nutrients requires an integrated response of the gastrointestinal tract to ingested food. Broad mechanisms are similar in all mammals and involve sensing food components through olfaction, taste and specialized receptors within the stomach and intestines. The sensing of food components leads to release of gut hormones and activation of nerves, which in turn modify dig...

Spray Dried, Pasteurised Bovine Colostrum Protects Against Gut Dysfunction and Inflammation in Preterm Pigs.

OBJECTIVE Feeding bovine colostrum (BC) improves gut maturation and function and protects against necrotizing enterocolitis, relative to formula in newborn preterm pigs. Before BC can be used for preterm infants, it is important to test if the milk processing, required to reduce bacterial load and increase shelf life, may affect bioactivity and efficacy of a BC product. METHODS We investigate...

Gut Melatonin in Vertebrates: Chronobiology and Physiology

Melatonin, following discovery in the bovine pineal gland, has been detected in several extra-pineal sources including gastrointestinal tract or gut. Arylalkylamine N-acetyltransferase (AANAT) is the key regulator of its biosynthesis. Melatonin in pineal is rhythmically produced with a nocturnal peak in synchronization with environmental light-dark cycle. A recent study on carp reported first t...

Physiology and Dysfunction

Copulation normally culminates with two physiologically distinct events known as emission and ejlzctllafion.3~ 3o Emission is the release of sperm and accessory gland fluids into the pelvic urethra. Ejacdafion is the forceful expulsion of the combined fluids (i.e., semen) from the urethra. The associated perceptual-cognitive event called ovgrrsm in humans has not been characterized in nonhuman ...
