To assess the prevalence of Parkinson’s disease and parkinsonism in two Spanish populations (Irun and Hondarribia, Bidasoa Region) and to compare the results with those of similar surveys. The survey included 2000 participants aged 65 years or older in a door-to-door, three-phase design. In the screening phase we used the SNES (Sicilian Neuro-Epidemiologic(More)
Over the past decade, antiproliferative effects of somatostatin and analogs have been reported in many somatostatin receptor-positive normal and tumor cell types. Regarding the molecular mechanisms involved, somatostatin or analogs mediate their action through both indirect and direct effects. Somatostatin acts through five somatostatin receptors (SSTR1-5)(More)
BACKGROUND & AIMS The somatostatin receptor SST2 mediates the antiproliferative effect of stable somatostatin analogues. SST2 gene expression is lost in most human pancreatic carcinomas. We investigated the mechanisms that could be involved in this defect. METHODS SST2 gene structure was investigated by sequencing and restriction fragment length(More)
Of 211 aborted bovine fetuses collected from Mexican dairy herds between January 1996 and March 1999, 73 showed microscopical lesions consistent with neosporosis. Of these 73 fetuses, 58 (79%) showed lymphocytic myocarditis, 39 (53%) showed microgliosis and multifocal necrosis in the brain, 39 (53%) showed lymphocytic hepatitis, and 19 (26%) showed(More)
The sst2 somatostatin receptor is an inhibitory G protein-coupled receptor, which exhibits anti-tumor properties. Expression of sst2 is lost in most human pancreatic cancers. We have cloned 2090 base pairs corresponding to the genomic DNA region upstream of the mouse sst2 (msst2) translation initiation codon (ATG). Deletion reporter analyses in mouse(More)
We report the production of a new monoclonal antibody, PNL2, directed against a fixative resistant melanocyte antigen. The analysis of PNL2 immunostaining on a broad range of normal or malignant human tissues and on various melanocytic lesions revealed its high specificity. PNL2 gave a strong cytoplasmic staining of skin and oral mucosae melanocytes, and(More)
An indirect enzyme-linked immunosorbent assay was used to obtain epidemiologic information on bovine neosporosis in dairy herds of the Mexican central plateau. Sera were collected from 1,003 cows from 50 dairy herds. Forty-three herds (group A) had been experiencing a high abortion rate. The abortion rates for the remaining 7 herds (group B) were within(More)
One hundred and ninety-three patients with oral lichen planus were evaluated retrospectively. Women outnumbered men by more than two to one. The mean age at lesion discovery was in the sixth decade. The buccal mucosa was the most common site of occurrence. There were concomitant systemic diseases in many of the patients. The ulcerative form was the most(More)
