BACKGROUND Adaptation to hypoxia and consequent pro-inflammatory gene expression of prostate and breast carcinomas have been implicated in the progression toward cancer malignant phenotype. Only partial data are available for the human tumor glioblastoma multiforme (GBM). The aim of our study was to analyze the hypoxic and pro-inflammatory microenvironment(More)
A search for narrow resonances in the dijet mass spectrum is performed using data corresponding to an integrated luminosity of 2.9 pb⁻¹ collected by the CMS experiment at the Large Hadron Collider. Upper limits at the 95% confidence level are presented on the product of the resonance cross section, branching fraction into dijets, and acceptance, separately(More)
The authors report their 27-year experience regarding 35 cases of supratentorial brain metastasis from sarcoma treated in a single institution: these included ten osteosarcomas, seven leiomyosarcomas, five Ewing sarcomas, four malignant fibrous histiocytomas, three alveolar soft-part sarcomas (ASPS), two rhabdomyosarcomas, one liposarcoma, and three(More)
We search for the technicolor process pp-->rhoT/omegaT-->WpiT in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb(-1), recorded by the D0 experiment at the Fermilab Tevatron. Technicolor predicts that technipions pi(T) decay dominantly into bb, bc, or bc, depending on their charge. In these events b(More)
BACKGROUND We review the surgical anatomy of the brain stem in relation to the surgical approaches adopted for treatment of cavernomas and identify possible "safe entry zones" on the anterior face of the brainstem. METHODS Twelve symptomatic patients with cavernoma or telangectasia of the brain stem were surgically treated. The brain stem was divided into(More)
Criteria to define the biochemical remission of acromegaly following surgery have changed over the years, and the current use of stringent criteria needs a critical re-evaluation of the surgical results. On the other hand, few data are currently available concerning the possible impact of pituitary surgery on the quality of life of operated acromegalic(More)
Transsphenoidal surgery (TSS) is a well recognised treatment for secreting pituitary adenomas, however a very wide variation of clinical outcomes and recurrence rates has been reported, depending on the different criteria used to define the cure. We reported the clinical outcome of a large series of patients operated on for a secreting pituitary adenoma(More)
OBJECTIVE Despite new endovascular techniques and technological advances in microsurgery, the treatment of giant intracranial aneurysms is still a daunting neurosurgical task. Many of these aneurysms have a large, calcified neck, directly involve parent and collateral branches, and are partly thrombosed. In this retrospective review, we focused our analysis(More)
Two cases are reported of Arnold-Chiari type I malformation associated with syringomyelia, in which magnetic resonance (MR) imaging revealed spontaneous decompression of the syrinx. In one case axial MR imaging sections showed a communication between the syrinx and the spinal subarachnoid space, which supports the hypothesis that fissuring of the cord(More)
Metastasis from extracranial tumor into an intracranial primary tumor is an uncommon event. A predominant tendency of meningioma to be the host tumor for breast carcinoma has been found. In the current report, three cases of breast carcinoma metastatic to intracranial meningiomas are described. In our cases, metastasis in meningioma was the first clinical(More)
