An immunohistochemical study was performed using tissue microarrays and specific antibodies against matrix metalloproteinases (MMPs) 1, 2, 7, 9, 11, 13, 14, and their tisullar inhibitors (TIMPs) 1, 2, and 3. More than 2600 determinations on cancer specimens from 131 patients with primary ductal invasive tumours of the breast (65 with and 66 without distant(More)
Fatty acids induce an increase in the transcription of the mitochondrial 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) synthase gene, which encodes an enzyme that has been proposed as a control site of ketogenesis. We studied whether the peroxisome proliferator-activated receptor (PPAR) is involved in the mechanism of this transcriptional induction. We found(More)
OBJECTIVES To determine the population-based incidence of community-acquired pneumonia (CAP) in adults and to assess the relative importance of age and gender on the incidence of infections caused by different microbial pathogens. METHODS A two-year prospective study in a well-defined geographic area of the Spanish Mediterranean coast. RESULTS The(More)
An immunohistochemical study was performed using tissue microarrays and specific antibodies against matrix metalloproteinase (MMP)-1, -2, -7, -9, -11, -13 and -14, tissular inhibitors of metalloproteinase (TIMP)-1, -2 and -3. More than 2600 determinations on cancer specimens from 131 patients with primary ductal invasive tumours of the breast were(More)
Molecular epidemiological studies suggest that particular Mycobacterium tuberculosis strains have an enhanced capacity to spread within a community. One strain, the Beijing genotype, has been associated with outbreaks in a number of communities throughout the world. IS6110 restriction fragment length polymorphism (RFLP) analysis was performed on M.(More)
In the present study we analyze, in patients with breast cancer, the tumor expression of androgen receptors (AR), its relationship with clinicopathological characteristics and with the expression of several matrix metalloproteases (MMPs) and their inhibitors (TIMPs), as well as with prognosis. An immunohistochemical study was performed using tissue(More)
The in vitro activity of moxifloxacin, gatifloxacin, levofloxacin and linezolid was evaluated against 234 strains of Mycobacterium tuberculosis isolated in the Southeast of Spain. All drugs tested showed good activity, with an MIC(90) of less than 1 mg/l, and were active against isociacide and rifampicin resistant strains. Three strains were resistant to(More)
OBJECTIVE Our aim was to study the influence of efflux pump systems in the resistance of Mycobacterium tuberculosis to fluoroquinolones and linezolid. METHODS We studied the mutations in gyrA and gyrB genes and the influence of efflux pump systems with 2 inhibitors (reserpine and MC 207.110). RESULTS The effect of the active efflux system on the(More)
We evaluated the Binax NOW rapid immunochromatographic membrane test (ICT) for detection of Streptococcus pneumoniae urinary antigen in a population-based prospective study of adults with community-acquired pneumonia (CAP). ICT was performed with urine samples obtained from 452 (91.7%) of 493 patients enrolled. Pneumococcal antigen was detected in 19(More)
Mycobacteria other than tuberculosis infections in patients taking various tumour necrosis factor (TNF)-alpha inhibitors have been reported in the literature. We describe sporotrichoid spread of Mycobacterium marinum in a man with Crohn's disease treated with infliximab. After starting ethambutol and rifampicin and discontinuing infliximab, a worsening(More)
