traumatic coronary artery-cameral fistulas (tcaf) are rare and may present secondary to penetrating injuries (80%) or iatrogenic traumas. early operative intervention remains the recommended treatment modality for accidental traumatic coronary artery fistulas. we report the case of a 17-year-old man who presented with left anterior descending coronary artery-right ventricle fistula following pe...

Bystander or non-targeted effect is known to be an interesting phenomenon in radiobiology. The genetic consequences of bystander effect on non-irradiated cells have shown that this phenomenon can be considered as one of the most important factors involved in secondary cancer after exposure to ionizing radiation. Every year, millions of people around the world undergo radiotherapy in order to cu...
