IκBα targeting promotes oxidative stress-dependent cell death.

Background: Oxidative stress is a hallmark of many cancers. The increment in reactive oxygen species (ROS), resulting from an increased mitochondrial respiration, is the major cause of oxidative stress. Cell fate is known to be intricately linked to the amount of ROS produced.

A Rare Case of Hodgkin Lymphoma of the Maxillary Sinus.

Hodgkin lymphoma (HL) is an uncommon B-cell malignant disease. It usually presents with mediastinal and/or laterocervical lymph node localization, while primary extranodal HL is a rare entity giving rise to diagnostic and therapeutic challenges. It rarely presents as just extranodal localization, so its presence within the maxillary sinus without any lymphadenopathy is exceptional.

Association between High On-Aspirin Platelet Reactivity and Reduced Superoxide Dismutase Activity in Patients Affected by Type 2 Diabetes Mellitus or Primary Hypercholesterolemia.

Platelet hyperactivation is involved in the established prothrombotic condition of metabolic diseases such as Type 2 Diabetes Mellitus (T2DM) and familial hypercholesterolemia (HC), justifying the therapy with aspirin, a suppressor of thromboxane synthesis through the irreversible inhibition of cyclooxygenase-1 (COX-1), to prevent cardiovascular diseases. However, some patients on aspirin show a higher than expected platelet reactivity due, at least in part, to a pro-oxidant milieu. The aim of this study was to investigate platelet reactivity in T2DM ( = 103) or HC ( = 61) patients (aspirin, 100 mg/day) and its correlation with biomarkers of redox function including the superoxide anion scavenger superoxide dismutase (SOD) and the in vivo marker of oxidative stress urinary 8-iso-prostaglandin F.

The Challenge of Hemorrhagic Shock Management During Low-Molecular-Weight Heparin Treatment.

The reversal of low-molecular-weight heparin (LMWH) and the management of bleeding patients on LMWH remain highly challenging. Even if LMWH is very extensively administered in the prophylaxis and treatment of venous thrombosis, specific antidotes are lacking, and reversal strategies have very weak grade of evidences on clinical effectiveness. We here describe a reversal strategy with protamine and FVIIa in a patient presenting with hemorrhagic shock and cardiocirculatory arrest.
