... after a meal. Throughout the telencephalon, cell proliferation was significantly increased in the 6 day group, with no difference between the 2 day group and controls. Systemic postprandial plasticity occurs quickly after a meal is ingested, during the period of active digestion; however, the brain...

... to occur in response to repeated elevations of O 2 demand and/or reduced O 2 supply in several species of vertebrate ectotherms, including postprandial Burmese pythons ( Python bivittatus ). Recent data suggest postprandial cardiac hypertrophy in P. bivittatus is a facultative rather than obligatory...

...-animal metabolism, and GI function and metabolism, we measured preprandial and postprandial metabolic rates and gastric and intestinal acid–base secretion, epithelial conductance and oxygen consumption for the frequently feeding diamondback water snake ( Nerodia rhombifer ) and the infrequently feeding...

... between gut blood flow and temperature choice after feeding ( R 2 =0.88±0.03, 6–8 h postprandially and R 2 =0.89±0.04, 8–10 h postprandially) but not prior to feeding ( R 2 =0.11±0.05). Feeding did not affect the actual temperature preference (18.4±0.7°C before feeding, 18.1±0.7°C, 6–8 h postprandially...

... absorbed ( Pappenheimer and Michel, 2003 ). In addition to these organ-specific needs of postprandial hyperemia is the general requirement for increased oxygen delivery to the active digestive tissues. Although we did not specifically measure gastric and pancreatic blood flow (pancreatic arteries do...

... balance regulation appears negligible in studies of unfed fish, but evidence of high intestinal fluid [HCO 3 − ] in fed marine teleosts led us to investigate the source of this HCO 3 − and its potential role in offsetting the postprandial ‘alkaline tide’ commonly associated with digestion. Specifically...

... and postprandial state, a distinct pattern with clusters of burst-like events interspersed by silent periods. The frequency of electrical events increased postprandially for both acclimation groups. Event frequency increased from 3.0±0.5 to 9.6±1.4 events min –1 and from 5.9±0.9 to 11.8±2.0 events min –1 in the 10...

...J. Matthias Starck; Ariovaldo P. Cruz-Neto; Augusto Shinya Abe SUMMARY Broad nosed caiman are ectotherm sauropsids that naturally experience long fasting intervals. We have studied the postprandial responses by measuring oxygen consumption using respirometry, the size changes of the duodenum...

... exertion and under postabsorptive and postprandial conditions to determine their effect on ADL. For each set of conditions, the model was also run at different levels of cardiac output (i.e. the dive response was varied) to determine the level of convective oxygen transport that optimized the ADL...

... rapidly than the rate of heat loss in a cooling environment. It may be hypothesized that the rate of cooling, particularly at relatively cool T b s, would be further reduced during postprandial periods when specific dynamic action (SDA) increases endogenous heat production (i.e. the heat increment...

... . O2 ) and ventilation ( V̇ . E ) were measured in lizards during fasting exercise, postprandial rest and postprandial exercise. In fasting animals, V̇ . O2 increased with walking speed to a maximal value of 15.9mlO 2 kg −1 min −1 at 1.25kmh −1 . Postprandial resting metabolic rate was elevated...

There is virtually no information on the cardiopulmonary response during the postprandial period in these animals or how...
