Summary: Rotation of the crystalline style in Ruditapes, and the inhalant and exhalant rates of the digestive gland in Mytilus, detected by magnetic resonance imaging with a contrast reagent, gadolinium-diethylenetriamine pentaacetic acid.

Summary: A combination of in vivo and in vitro studies reveals that the corticotropin-releasing factor system serves osmoregulatory functions in the intestine of Atlantic salmon.

Summary: Jellyfish amoebocytes promote photosynthesis by their endosymbiotic algae using proton pumps and carbonic anhydrases. These two enzymes ubiquitously acidify phagosomes, lysosomes and invertebrate guts, establishing functional and evolutionary links between symbiosis, food digestion and immunity.

Summary: Heteropteran insects and their bacterial symbionts undergo reciprocal changes in cellular morphologies and behaviors during the establishment of their symbiotic relationship.

Summary: Digestive acidification in hagfish is mediated by VHA and the cAMP pathway and VHA performs both invertebrate- and gnathostome-like digestive functions.

Summary: In vivo, in situ and in vitro experiments with novel chyme-filled gut sacs show that more than 50% of the postprandial exogenous ammonia and urea nitrogen excretion originates from the gut.
