A growing number of human neurodegenerative diseases result from the expansion of a glutamine repeat in the protein that causes the disease. Spinocerebellar ataxia type 1 (SCA1) is one such disease-caused by expansion of a polyglutamine tract in the protein ataxin-1. To elucidate the genetic pathways and molecular mechanisms underlying neuronal degeneration(More)
The genomic region encompassing the Major Histocompatibility Complex (MHC) contains polymorphic frozen blocks which have developed by local imperfect sequential duplication associated with insertion and deletion (indels). In the alpha block surrounding HLA-A, there are ten duplication units or beads on the 62.1 ancestral haplotype. Each bead contains or(More)
In this paper we present the analysis of nucleolar organizer regions (NORs) in five species of the order Pleuronectiformes (Scophthalmus maximus, Scophthalmus rhombus, Platichthys flesus, Solea solea and Solea lascaris), a group of fish poorly studied cytogenetically. In spite of the small chromosome sizes, which characterize the karyotypes of this group,(More)
The detection of microsatellite sequences within expressed sequence tags (ESTs) connects potential markers with specific genes, generating type I markers. We have developed and mapped by linkage analysis a set of EST-derived microsatellites in the turbot, Scophthalmus maximus. One hundred and ninety-one microsatellites were identified from 9256 turbot ESTs.(More)
We have analyzed the localization of the highly conserved telomeric sequence (TTAGGG)n in four salmonid species, two of the genus Salmo (Salmo trutta and Salmo salar) and two of the genus Oncorhynchus (Onchorhynchus mykiss and Onchorhynchus kisutch), by fluorescent in situ hybridization. As expected, the hybridization signal was mostly localized at the(More)
Acinetobacter baumannii has been increasingly associated with hospital-acquired infections, and the presence of multidrug resistance strains is of great concern to clinicians. A. baumannii is thought to possess a great deal of intrinsic resistance to several antimicrobial agents, including chloramphenicol, although the mechanisms involved in such resistance(More)
The genetic variation of brown trout from Duero, one of the main Atlantic Iberian river basins, was assessed at 34 enzymatic loci in 62 native populations. A strong intrabasin differentiation was detected (G(ST) = 0.46; range D: 0-0.066), mainly attributable to the existence of two divergent groups of populations within Duero: southern and northern groups.(More)
BACKGROUND Neutrophil to lymphocyte ratio (NLR), an index of systemic inflammation, has been associated with worse survival for many types of cancer. The aim of this study is to investigate the clinical significance of the blood NLR as a prognostic factor in non-small cell lung cancer (NSCLC) patients. METHODS AND PATIENTS Stage IV NSCLC patients(More)
PURPOSE TP53 mutations have been described in chronic lymphocytic leukemia (CLL) and have been associated with poor prognosis in retrospective studies. We aimed to address the frequency and prognostic value of TP53 abnormalities in patients with CLL in the context of a prospective randomized trial. PATIENTS AND METHODS We analyzed 529 CLL samples from the(More)
INTRODUCTION The K-SADS-PL diagnostic interview is useful for the cross-sectional and longitudinal evaluation of psychopathology in children and adolescents. The objective of this article was to describe the interrater reliability of the Spanish version of the Schedule for Affective Disorders and Schizophrenia for School-Age Children--Present and Lifetime(More)
