The effect of meal temperature on heart rate in Rhodnius prolixus

Show abstract
Rhodnius prolixus is able to cool down the ingested blood during feeding on a warm-blooded host. This is possible because of a counter-current heat exchanger located in its head, which transfers heat from the warm blood to the insect haemolymph and can dissipate through the head cuticle. Given the key role haemolymph circulation in thermoregulation, we investigated the modulation of the activity of the heart during the warmed meal intake. We evaluated the impact of meal temperature on the heart rate and found that feeding led to an increase in the frequency of heart contractions, which increases with increasing food temperature. We also found that females have a higher heart rate during feeding compare to males.\n\nHIGHLIGHTSO_LIFeeding increases the heart rate of Rhodnius prolixus\nC_LIO_LIThe higher the meal temperature, the higher the heart rate becomes\nC_LIO_LIFemales have a higher heart rate than males\nC_LI

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
