Hypoxia-Inducible Factor-2α Promotes Liver Fibrosis by Inducing Hepatocellular Death.

The activation of hypoxia-inducible factors (HIF)-1α and 2α in the liver is closely linked to the progression of fatty liver diseases. Prior studies indicated that disrupting hepatocyte HIF-2α attenuates diet-induced hepatic steatosis, subsequently decreasing fibrosis. However, the direct role of hepatocyte HIF-2α in liver fibrosis has not been addressed.

Advanced Stage Hodgkin and Diffuse Large B-Cell Lymphomas: Is There Still a Role for Consolidation Radiotherapy in the PET Era?

The role of radiotherapy in the treatment of lymphoma is rapidly evolving. The development of modern systemic therapies and the adoption of FDG-PET-scanning as metabolic prognosticators are leading to a process of refinement of the treatment regimens. In this scenario, radiotherapy utilization is decreasing in several settings, including lower risk patients, to prevent the risk of long-term complications.

Efficacy and Low Toxicity of Normo-Fractionated Re-Irradiation with Combined Chemotherapy for Recurrent Glioblastoma-An Analysis of Treatment Response and Failure.

Background: Glioblastoma is the most common malignant brain tumor in adults. Even after maximal safe resection and adjuvant chemoradiotherapy, patients normally relapse after a few years or even months. Standard treatment for recurrent glioblastoma is not yet defined, with re-resection, re-irradiation, and systemic therapy playing key roles.
