Pridopidine has demonstrated improvement in Huntington Disease (HD) motor symptoms as measured by secondary endpoints in clinical trials. Originally described as a dopamine stabilizer, this mechanism is insufficient to explain the clinical and preclinical effects of pridopidine. This study therefore explored pridopidine's potential mechanisms of action. The effect of pridopidine versus sham tre...

PURPOSE The well-known translocations identified in MALT lymphomas include t(11;18)/API2-MALT1, t(1;14)/IGH-BCL10, and t(14;18)/IGH-MALT1. Molecular investigations have suggested that these three disparate translocations affect a common pathway, resulting in the constitutive activation of nuclear factor-kappaB. However, the vast majority of MALT lymphomas are negative for any of the above-menti...

The regulation of monopolistic firms has been widely investigated in the economic literature. Particular emphasis has been placed on the relationship between the regulated monopolist and the regulator. The present work deals with problems that may arise from the presence of several regulators. If regulators have different objective functions, inefficiency is likely to arise. A theoretical model...

Purpose: Alveolar soft part sarcoma (ASPS) is a soft tissue sarcoma with poor prognosis, and little molecular evidence exists for its origin, initiation, and progression. The aim of this study was to elucidate candidate molecular pathways involved in tumor pathogenesis. Experimental Design: We employed high-throughput array comparative genomic hybridization (aCGH) and cDNA-Mediated Annealing, S...

BACKGROUND Mxi1, an antagonist of c-Myc, maps to human chromosome 10q24-q25, a region altered in a substantial fraction of prostate tumors. Mice deficient for Mxi1 exhibit significant prostate hyperplasia. We studied the ability of Mxi1 to act as a growth suppressor in prostate tumor cells. METHODS We infected DU145 prostate carcinoma cells with an Mxi1-expressing adenovirus (AdMxi1) in vitro...

A 70-year-old man was diagnosed with stage IVA follicular lymphoma grade 1 in 2005. He initially received rituximab treatment in 2006. In the next 5 years, he was enrolled in several clinical trials including Zevalin radioimmunotherapy in 2007. He was recently admitted due to a new onset of gastrointestinal bleeding. At admission, a complete blood count showed mild anemia, severe thrombocytopen...

OBJECTIVE the main aim of this study was to describe the authors' experience with the surgical treatment of endometrial cancer without systematic lymphadenectomy. METHODS a retrospective cohort study was carried out on a subset of patients suffering of clinically early-stage endometrial carcinoma who underwent hysterectomy and salpingo-oophorectomy without systematic (radical) lymph nodes dis...

We examined 33 primary gastric carcinomas using comparative genomic hybridization to detect changes in the DNA copy number and the chromosomal location of these changes. Ninety-four percent (31 of 33) showed 1 or more DNA copy number changes, such as increases at 2p23-p25 (observed in 21% of the total cases), 3q26.3-q27 (24%), 7p15 (24%), 9p22-pter (18%), and 13q22-q34 (21%) and decreases at 1p...

Primary open-angle glaucoma (POAG) is a highly prevalent cause of irreversible blindness which associates cupping of the optic disc and alteration of the visual field, elevation of intraocular pressure being a major risk factor. Provided diagnosis is made at an early stage, treatments are available to prevent visual impairment. A locus, GLC1A, has been mapped on chromosome 1q23-q25 in several f...

Non-retroperitoneal dedifferentiated liposarcoma (DDLS) is relatively uncommon and its characterization at the molecular genetic level has been limited. We describe the cyto-genetic and molecular cytogenetic findings of giant DDLS arising in the right thigh of an 83-year-old woman. Magnetic resonance imaging revealed a mass composed of two components with heterogeneous signal intensities, sugge...
