In this work, we describe a multiplex PCR assay for the detection of clinically relevant antibiotic resistance genes harbored by some Staphylococcus aureus isolates and for the simultaneous identification of such isolates at the species level. Conditions were optimized for the simultaneous detection of the 310-, 456-, and 651-bp regions of the mecA(More)
BACKGROUND The epithelial Ca(2+) channel (ECaC) exhibits the defining properties for being the gatekeeper in 1,25-dihydroxyvitamin D(3)-regulated Ca(2+) (re)absorption. Its recently cloned human orthologue (ECaC1) could, therefore, represent a crucial molecule in human disorders related to Ca(2+)-wasting such as idiopathic hypercalciuria (IH). METHODS(More)
Dent's disease is an X-linked recessive renal tubulopathy characterized by low-molecular-weight proteinuria (LMWP), hypercalciuria, nephrocalcinosis, nephrolithiasis, and progressive renal failure. LMWP is the most constant feature, while the other clinical manifestations show wide variability. Patients also present variable manifestations of proximal(More)
Bartter syndrome (BS) is a heterogeneous group of autosomal recessive hypokalaemic salt-losing tubulopathies. Five types of BS caused by different genetic defects have been identified, and one of them is associated with sensorineural deafness (BSND). Mutations in the recently described BSND gene, mapped in chromosome 1p31, have been reported to be(More)
Functional and morphological analyses indicated that the epithelial Ca2+ channel (ECaC), which was recently cloned from rabbit kidney, exhibits the defining properties for being the gatekeeper in transcellular Ca2+ (re)absorption. Its human homologue provides, therefore, a molecular basis for achieving a better understanding of Ca2+ mal(re)absorption. By(More)
The experimental transfer of the vanA gene cluster from Enterococcus faecalis to Staphylococcus aureus has raised fears about the occurrence of such genetic transfer in clinical isolates of methicillin-resistant staphylococci. Recently, infections by a S. aureus strain carrying the enterococcal vancomycin resistance vanA gene cluster were reported. The(More)
Mutations in the gene coding for the renal tight junction protein claudin 16 cause familial hypomagnesemia with hypercalciuria and nephrocalcinosis, an autosomal recessive disorder of renal Ca(2+) and Mg(2+) handling that progressively leads to chronic renal failure, with nephrolithiasis having been reported in heterozygous carriers. Screening a cohort of(More)
Dent's disease is an X-linked renal tubular disorder characterized by low-molecular-weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis, and eventual renal failure. Various types of mutations in the renal chloride channel gene, CLCN5, have been identified in patients with this disease. We studied a Spanish patient with Dent's disease and(More)
Alu sequences are short, interspersed elements that have generated more than one million copies in the human genome. They propagate by transcription followed by reverse transcription and integration, causing mutations, recombination, and changes in pre-mRNA splicing. We have recently identified a 345-bp long Alu Ya5 element inserted in codon 650 within exon(More)
