Specific microRNA (miRNA) signatures have been associated with different cytogenetic subtypes in acute leukemias. This finding prompted us to investigate potential associations between genetic abnormalities in multiple myeloma (MM) and singular miRNA expression profiles. Moreover, global gene expression profiling was also analyzed to find correlated miRNA(More)
In the last few years, the detection of free radical damage and the body's defences against it have become increasingly important in clinical medicine as a complementary tool in the evaluation of metabolic status. The aim of this study was to evaluate, under field conditions, the anti-oxidant status of healthy cows during late pregnancy and lactation onset(More)
The frequency of hepatitis C virus (HCV) infection in Spain was assessed by means of a recombinant-based immunoassay for serum anti-HCV antibodies. 836 serum samples were tested from 676 patients selected according to their risk of blood-borne viral infections and presence of liver disease. Among patients at high risk of infection (with or without liver(More)
Recently, a consensus International Prognostic Scoring System (IPSS) for predicting outcome and planning therapy in the myelodysplastic syndromes (MDS) has been developed. However, the intermediate-risk cytogenetic subgroup defined by the IPSS includes a miscellaneous number of different single abnormalities for which real prognosis at present is uncertain.(More)
BACKGROUND Picornaviruses are responsible for a wide range of mammalian diseases and, in common with other RNA viruses, show considerable antigenic variation. Foot-and-mouth disease viruses (FMDVs) constitute one genus of the picornavirus family and are classified into seven serotypes, each of which shows considerable intratypic variation. This antigenic(More)
Recent results have revealed novel features in the process of antigenic diversification of FMDV. (i) Antigenic variation is not necessarily the result of immune selection. (ii) Single, critical amino acid replacements may either have a minor effect on antigenic specificity or cause a drastic antigenic change affecting many epitopes on an antigenic site.(More)
Knowledge of trace and toxic metal concentrations in livestock is important for assessing the effects of pollutants on domestic animals and contaminant intakes by humans. Metal levels in cattle have been measured in various countries but not in Spain. In this study, the (wet wt.) concentrations of three toxic elements (arsenic, cadmium, lead) and two trace(More)
We have evaluated the use of a fluorescent in situ hybridization (FISH) technique for the detection of Helicobacter pylori in water (river and wastewater) samples. The assay was compared with PCR detection and isolation of cells on selective media. 16S rRNA and UreA+B sequence data were used as oligonucleotide probe and specific primers for FISH and PCR,(More)
Although the immunophenotype of plasma cells (PCs) from multiple myeloma (MM) patients has been extensively explored, information on the phenotypic characteristics of PCs in monoclonal gammopathy of undetermined significance (MGUS) patients is scanty and frequently controversial. Thus, the question of whether or not PCs are phenotypically different in the(More)
The incidence of colonization by enteropathogenic, enterotoxigenic, enteroinvasive, and enterohemorrhagic Escherichia coli (detected by DNA hybridization with specific radiolabeled probes), Salmonella sp., Shigella sp., Campylobacter jejuni, and rotavirus was related to the presence of diarrhea in a cohort of 75 rural infants followed longitudinally during(More)
