[A taste of honey : Rare cause of syncope associated with junctional rhythm].

We present a rare reversible cause of bradycardia. A 49-year-old man who suffered from syncope was administered to our emergency department. In preclinical ECG recordings, a sinus node arrest was documented.

Oxidative stress-induced retinal damage is prevented by mild hypothermia in an ex vivo model of cultivated porcine retinas.

Background: Hydrogen peroxide (H O ) can be used in vitro to simulate oxidative stress. In retinal organ cultures, H O induces strong neurodegeneration of the retina. It is known that oxidative stress plays a role in the development of several retinal diseases including glaucoma and ischemia.
