BACKGROUND AND PURPOSE WM lesion segmentation is often performed with the use of subjective rating scales because manual methods are laborious and tedious; however, automated methods are now available. We compared the performance of total lesion volume grading computed by use of an automated WM lesion segmentation algorithm with that of subjective rating scales and expert manual segmentation in...

OBJECTIVE Mutations in the p53 gene are the most commonly observed genetic abnormalities in malignancies. The purpose of this study was to assess the diagnostic value of serum anti-p53 antibody (Ab) along with the correlation between serum anti-p53 Ab level and quantitative positron emission tomography (PET) parameters such as maximum standardized uptake value (SUVmax), SUVave, metabolic tumor ...

The cyclops lesion is a localized anterior arthrofibrosis most commonly seen following anterior cruciate ligament reconstruction. The lesion forms at the anterior cruciate ligament insertion creating a painful extension block between femoral intercondylar notch and tibial plateau. We present 2 cases (3 knees) in which cyclops lesions appeared atypically following bicruciate-retaining total knee...

Background: Among different mechanisms, oxidative stress has a possible role in neural injury in cerebrovascular events. Objectives: Assessment the oxidants-antioxidants imbalance in ischemic and hemorrhagic strokes. Materials and Methods: Serum level of malondialdehyde, the main marker of lipid peroxidation, and total antioxidant capacity were measured in a group of 48 stroke patients consis...

RATIONALE The adult brain maintains the ability for reorganization or plasticity throughout life. Non-invasive techniques such as functional magnetic resonance imaging (f-MRI), Transcranial Magnetic Stimulation (TMS) and magnetoencephalography could be used to show recovery of function after stroke. OBJECTIVE Explanation of neuronal plastisity and intra-hemisferic reorganization with function...

Our previous reports have presented evidence suggesting the existence in tumor cells of a second control site of glycolysis of pyruvate kinase as a competition for adenosine diphosphate between this enzyme and mitochondria, which is responsible for the Crabtree effect. Now, by using cells partially permeabilized to nucleotides and phosphorylated substrates, we provide evidence supporting the ex...

This study investigated the prognostic value of metabolic parameters determined by 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in patients with stage III gastric cancer. Patients with pre-operative PET/CT and confirmed stage III after curative surgical resection were retrospectively enrolled. Parameters evaluated from pre-operative PET/CTwere maximum s...
