Tau phosphorylation was examined in argyrophilic grain disease (AGD) by using the phosphospecific tau antibodies Thr181, Ser202, Ser214, Ser 396 and Ser422, and antibodies to non-phosphorylated and phosphorylated mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinases (ERK), stress-activated kinase (SAPK), c-Jun N-terminal kinase(More)
The pro-form of nerve growth factor (pro-NGF) has been shown to be a high affinity ligand for p75NTR and to induce apoptosis through this receptor. It has been reported that pro-NGF, rather than mature NGF, is the predominant form of this neurotrophin in human brain. In the present work we studied the potential involvement of pro-NGF purified from human(More)
Mutations in APP are associated with familial early-onset Alzheimer disease (FAD). Examination of the genomic sequence in one patient with FAD revealed a change located in the axon 17 of the APP gene at position 275329G>A (GenBank accession number: D87675; GI: 2429080); cDNA sequence 2137G>A (GenBank accession number: X06989; GI: 28720). This corresponds to(More)
PURPOSE A prospective, two-stage phase II trial with octreotide in patients with recurrent high-grade meningioma was conducted. The radiographic partial response (RPR) was set as the primary study endpoint, whereas progression-free survival at 6 months (PFS6) was defined as the secondary endpoint. METHODS Nine patients (eight men; median age 65) with(More)
BACKGROUND Hereditary myopathy with early respiratory failure (HMERF) was described in several North European families and recently linked to a titin gene (TTN) mutation. We independently studied HMERF-like diseases with the purpose to identify the cause, refine diagnostic criteria, and estimate the frequency of this disease among myopathy patients of(More)
Deposition of amyloid-beta, the fibrillogenic product of the cell surface protein AbetaPP (amyloid-beta protein precursor), occurs in the cerebral cortex of patients with Dementia with Lewy bodies (DLB). Amyloid deposition, basically in the form of senile plaques, occurs not only in the common form (DLBc), which is defined by changes consistent with diffuse(More)
Expression of IGFBP2 (Insulin-like Growth Factor Binding Protein 2) has been positively correlated with glioma progression. Although the proteolysis of IGFBP2 has been widely recognized, with consequences as a major modulator of IGFII signaling, the relevance of this post-translational modification has not been well studied in tumors. Using an in vivo(More)
INTRODUCTION Intracranial schwannomas not related to cranial nerves are uncommon brain tumours. Such tumours account for less than 1% of all surgically treated schwannomas. Only 79 cases have been reported in the literature. METHODS We describe two cases treated in our centre. The patients are young women with seizures as a presenting symptom. Both(More)
BACKGROUND Primary central nervous system lymphomas may present as diffuse, nonenhancing infiltrative lesions. This rare variant is termed lymphomatosis cerebri (LC). We did a systematic review and analysis of the literature, adding our own cases, to better characterize LC in order to improve early diagnosis and treatment. METHODS PubMed, ISI Web of(More)
