Using a rapid Fourier SSFP imaging technique, which is sensitive to slow flow (approximately 1 mm/sec) in the plane of the image, we obtained 135 brain MRI examinations. The CSF flow/motion patterns were mapped by two images with orthogonal in plane flow sensitivity directions. Analysis showed significant deviations from the "normal" pattern in ventricular(More)
We studied whether thymidylate synthase (TS) genotype has an independent prognostic/predictive impact on a European population of advanced non-small cell lung cancer (NSCLC) patients receiving pemetrexed. Twenty-five patients treated with pemetrexed-based regimens were included. Genomic DNA was isolated prior to treatment. The variable number of tandem(More)
Many antitumor therapies affect rapidly dividing cells. However, tumor proliferation may be driven by cancer stem cells (CSCs), which divide slowly and are relatively resistant to cytotoxic drugs. Thus, many tumors may progress because CSCs are not sensitive to the treatment. In this work, we searched for target genes whose expression is involved in(More)
The metabolism of isopropylcyclohexane and associated renal pathology were evaluated in male Fischer 344 rats exposed by oral gavage. The rats experienced moderate proximal tubular damage similar to that produced by acyclic, branched-chain hydrocarbons. The urinary metabolites of isopropylcyclohexane included cis-4-isopropylcyclohexanol,(More)
UNLABELLED What's known on the subject? and What does the study add? SXR and MDR1 are known as responsible for chemo and radiotherapy resistance in some cancers, like kidney cancer (MDR1). Invasive bladder cancer is an aggressive disease, with different behaviour upon its tumoral stage, and also within the same tumoral stage, therefore molecular markers are(More)
AIM To investigate the angiogenesis-related protein expression profile characterizing metastatic colorectal cancer (mCRC) with the aim of identifying prognostic markers. METHODS The expression of 44 angiogenesis-secreted factors was measured by a novel cytokine antibody array methodology. The study evaluated vascular endothelial growth factor (VEGF) and(More)
Inhibitor of DNA binding 1 (Id1) and 3 (Id3) genes have been related with the inhibition of cell differentiation, cell growth promotion and tumor metastasis. Recently, Id1 has been identified as an independent prognostic factor in patients with lung adenocarcinoma, regardless of the stage. Furthermore, Id1 may confer resistance to treatment (both,(More)
Id1 has been shown to play a critical role in tumorigenesis and angiogenesis. Moreover, recent reports have involved Id1 in the maintenance of cancer stem cell features in some tumor types. The Id1 gene generates two isoforms through alternative splicing: Id1a and Id1b. We have investigated the role of each isoform in cancer development. Using lentiviral(More)
BACKGROUND In the prostate-specific antigen era, potentially indolent prostate tumors are radically treated, causing overtreatment. Molecular prognostic factors might differentiate indolent from aggressive tumors, allowing avoidance of unnecessary treatment. PATIENTS AND METHODS Fifty-two prostate cancer patients (20 organ-confined and 32 metastatic) were(More)
