Recently low dose irradiation has gained attention in the field of radiotherapy. For lack of understanding of the molecular consequences of low dose irradiation, there is much doubt concerning its risks on human beings. In this article, we report that low dose irradiation is capable of blocking the oncogenic KRAS-induced malignant transformation. To address this hypothesis, we showed that low d...
Previously, we showed that lipocalin2 (LCN2) serum levels increased after liver irradiation and during acute-phase conditions. Here, we evaluate LCN2 expression and serum levels after single-dose lung irradiation with 25 Gy, percutaneously administered to the lung of randomly-paired male Wistar rats. Due to the concave anatomy of the lung recesses, the irradiation field included the upper part ...
Background: In cervical postoperative radiotherapy, the target volume is usually the same as the extension of the previous dissection. We evaluated a protocol of selective irradiation according to the risk estimated for each dissected lymph node level. Methods: Eighty patients with oral/oropharyngeal cancer were included in this prospective clinical study between 2005 and 2008. Patients underwe...

ISSN 0001-5555 The 2008 WHO–EORTC classification for cutaneous lymphomas identifies 3 main subtypes of primary cutaneous B-cell lymphoma, including primary cutaneous diffuse large B-cell lymphoma, leg-type (PCLBCL, LT) (1), which is predominantly found in elderly people and has clinical feature...
Montmorillonite/ZrO2 nanocomposites were prepared by the sol-gel method underultrasonic irradiation. The montmorillonite was incorporated into Zirconium gel. After stirring for 24 hr, the mixture was irradiated for 30 min under ultrasonic irradiation. The filtrated composite gel was calcinated at 400°C for 3h in furnace. The morphology of prepared catalysts was characterized by field emis...
