To evaluate the GH regulating mechanism in acromegalic patients, post-inhibitory rebound rise in GH secretion induced by somatostatin was studied in these cases and normal subjects, and was compared with the rebound GH rise induced by dopamine. After somatostatin infusion (500 micrograms/75 min) both 5 normal and 9 acromegalic subjects showed prompt GH decreases during the infusion (% decrease:...

The postinhibitory rebound excitation is an intrinsic property of thalamic and cortical neurons that is implicated in a variety of normal and abnormal operations of neuronal networks, such as slow or fast brain rhythms during different states of vigilance as well as seizures. We used dual simultaneous intracellular recordings of thalamocortical neurons from the ventrolateral nucleus and neurons...

Abstract Drop rebound after collision with a very hot substrate is usually attributed to the Leidenfrost effect, characterized by intensive film boiling in thin vapour gap between liquid and substrate. Similarly, drop impact onto cold superhydrophobic leads complete rebound, despite partial wetting of Here we study repellent properties smooth hydrophilic substrates nucleate boiling, non-Leidenf...

150 years ago, Stanley Jevons introduced the concept of energy rebound: that anticipated energy efficiency savings may be “taken back” by behavioural responses. This is an important issue today because, if energy rebound is significant, this would hamper the effectiveness of energy efficiency policies aimed at reducing energy use and associated carbon emissions. However, empirical studies which...
