A simple, low-cost and fast Peltier thermoregulation set-up for electrophysiology.

Most of the parameters recorded in electrophysiology are strongly temperature dependent. In order to control temperature fluctuations we have built a system that ensures an accurate thermoregulation of the recording chamber. Temperature of physiological preparations can be changed relatively quickly (about 8 degrees C/min) and with a good accuracy (+/- 0.

[Spontaneous rupture of the ascending aorta: a diagnostic and therapeutic emergency. Report of 2 cases].

The authors report two cases of spontaneous rupture of the ascending aorta complicating atheromatous disease but without traumatic or infectious factors. The clinical presentation is very similar to that of dissection of the aorta. The diagnosis is based on non-invasive and invasive investigations showing localised abnormalities of the aortic wall suggestive of localised dissection and haemopericardium.
