BACKGROUND Merkel cell polyomavirus (MCPyV) has been detected in approximately 75% of patients with the rare skin cancer Merkel cell carcinoma. We investigated the prevalence of antibodies against MCPyV in the general population and the association between these antibodies and Merkel cell carcinoma. METHODS Multiplex antibody-binding assays were used to(More)
There is increasing concern about the potential neurotoxic effects of exposure to methylmercury in Amazonian populations due to mercury (Hg) release from gold-mining activities. A preliminary study was undertaken in two villages on the Tapajos River, an effluent of the Amazon, situated over 200 km downstream from the extraction areas. The study population(More)
To determine an optimal b value to visualise prostate cancer using diffusion-weighted magnetic resonance imaging at 3 T. Forty one patients with biopsy proven prostate cancer underwent 3 T diffusion-weighted MRI performed with 5 b values (0, 1,000, 1,500, 2,000, 2,500 s/mm2) using a 16-channel coil. Best lesion visibility, the central gland-lesion (CG-L)(More)
The mercury rejected in the water system, from mining operations and lixiviation of soils after deforestation, is considered to be the main contributors to the contamination of the ecosystem in the Amazon Basin. The objectives of the present study were to examine cytogenetic functions in peripheral lymphocytes within a population living on the banks of the(More)
PURPOSE To evaluate the outcome and success of refractive surgery in pre-presbyopic and presbyopic patients with monovision after laser in situ keratomileusis (LASIK). METHODS We performed a retrospective analysis of 748 eyes of 374 patients over 35 years of age treated in one or both eyes for a monovision outcome using the Alcon LADARVision 4000 laser.(More)
PURPOSE Intrastromal Ferrara ring segments were inserted in eyes with severe keratoconus to evaluate safety and efficacy of this procedure. METHODS Intrastromal Ferrara ring segments were placed in 36 eyes of 35 patients with severe keratoconus, who were evaluated after 12 months of follow-up. All patients had highly disabling visual acuity, contact lens(More)
Amplified fragment length polymorphism (AFLP) marker system has had broad applications in biology. However, the anonymous AFLP markers are mainly amplified from non-coding regions, limiting their usefulness as a functional marker system. To take advantages of the traditional AFLP techniques, we propose substitution of a restriction enzyme that recognizes a(More)
