...Ayelén Melisa Blanco; Jessica Calo; José Luis Soengas ABSTRACT The gut and brain are constantly communicating and influencing each other through neural, endocrine and immune signals in an interaction referred to as the gut–brain axis. Within this communication system, the gastrointestinal tract...

...Sean A. Williamson; Stephanie K. Courtney Jones; Adam J. Munn Phenotypic plasticity of organ size allows some animals to manage fluctuations of resource quality or availability. Here, we examined the phenotypic plasticity of the gastrointestinal tract of king quail ( Coturnix chinensis ) in a diet...

...Agustí Muñoz-Garcia; Sarah E. Aamidor; Marshall D. McCue; Scott R. McWilliams; Berry Pinshow SUMMARY During migratory flight, the mass of the gastrointestinal tract (GIT) and its associated organs in small birds decreases in size by as much as 40%, compared with the preflight condition because...

... expressed in the stomach. This Rh expression profile in toadfish is reminiscent of human and murine models that maintain significant quantities of RhBG and RhCG mRNA and protein in the liver, gastrointestinal tract, kidney and brain ( Liu et al., 2000 ; Liu et al., 2001 ; Weiner et al., 2003 ; Weiner...

... conclusion is that the transitional epithelium of caimans and squamates is the plesiomorphic condition. The avian-type flexibility of the gut, based on turn-over of cells, appears to be a derived feature of that clade. Although little is known about the postprandial size changes of the gastrointestinal tract...

...Carol Bucking; Chris M. Wood SUMMARY The temporal effects of feeding and digestion on chyme composition,specifically water and solid content, and net fluxes across the gastrointestinal tract, as well as plasma parameters, were examined in freshwater rainbow trout. A single meal of commercial dry...
