The immediate placement of implants in the fresh extraction sockets of infected teeth with periradicular and periapical lesions is contraindicated because of both the infection and the loss of architecture required for proper implant placement. There are 4 approaches for implant replacement of a hopeless tooth with lesions: (1) extraction and delayed implant placement; (2) extraction, debrideme...
Pedestrian impact testing is used to assess the relative level of protection from a vehicle to a pedestrian in the event of a collision. Testing is conducted as part of new car assessment programs (Euro NCAP, ANCAP), and for compliance with regulations in Europe and Japan. A key component of pedestrian impact testing is the head-form test, in which a dummy head-form is fired into the front of t...
Some aspects, both experimental and theoretical, of extracting the neutron skin ∆R from properties of isovector giant resonances are discussed. Existing proposals are critically reviewed. The method relying on the energy difference between the GTR and IAS is shown to lack sensitivity to ∆R. A simple explanation of the linear relation between the symmetry energy and the neutron skin is also pres...
Importance Glioblastoma multiforme (GBM) remains almost invariably fatal despite optimal surgical and medical therapy. The association between the extent of tumor resection (EOR) and outcome remains undefined, notwithstanding many relevant studies. Objective To determine whether greater EOR is associated with improved 1- and 2-year overall survival and 6-month and 1-year progression-free surv...
PURPOSE Neural progenitor cells in the subventricular zone (SVZ) have a controversial role in glioblastoma multiforme (GBM) as potential tumor-initiating cells. The purpose of this study was to examine the relationship between radiation dose to the SVZ and survival in GBM patients. METHODS AND MATERIALS The study included 116 patients with primary GBM treated at the Johns Hopkins Hospital bet...

BACKGROUND Recent studies suggest aggressive management combining a grossly total resection (GTR) with adjuvant radiotherapy (RT) as a treatment of choice for intracranial hemangiopericytoma (HPC). However, in these papers, the definitions of complete or GTR are equivocal. In the present study, we reviewed the relevant cases from our experience focused on the clinical efficacy of surgical gradi...
