OBJECTIVE To investigate chaperone-mediated autophagy in the pathogenesis of Parkinson disease (PD). DESIGN Postmortem observational study. SETTING University Department of Clinical Neuroscience, Institute of Neurology, University College London. SUBJECTS Postmortem samples from 7 PD, 6 Alzheimer disease (AD), and 8 control brains. MAIN OUTCOME(More)
BACKGROUND Epidermal growth factor receptor (EGFR) is overexpressed in a variety of epithelial malignancies including lung cancer. A soluble fragment of the EGFR extracellular domain (sEGFR) can be detected in the blood of patients who have non-small-cell lung cancer (NSCLC), but its clinical/ prognostic role must be further elucidated. METHODS sEGFR(More)
BACKGROUND Qualitative analysis of circulating DNA in the blood is a promising non-invasive diagnostic and prognostic tool. Our aim was to study the association between the presence of KRAS mutations at codon 12 and several clinical variables in advanced non-small cell lung cancer (NSCLC) patients. METHODS We examined 308 stage IIIB and IV NSCLC patients(More)
BACKGROUND Platinum doublets are standard chemotherapy for advanced non-small-cell lung cancer (NSCLC). The aim of this study was to assess whether neutropenia is: (1) an indicator for treatment efficacy, or (2) associated with specific polymorphisms. PATIENTS AND METHODS Four hundred ninety-four patients, treated with cisplatin-docetaxel were(More)
BACKGROUND The aim of the present study was to evaluate the efficacy and toxicity of weekly paclitaxel as second- or third-line treatment in non-small cell lung cancer (NSCLC) patients. MATERIALS AND METHODS The outcome measured in 37 patients were: response rates, symptom relief (dyspnoea, asthenia and pain), toxicity, overall survival (OS) and time to(More)
The purpose of this analysis was to study the association between the quantity of free circulating DNA and clinical variables in 99 advanced non-small cell lung cancer patients (NSCLC). The quantification in the serum of the gene of the catalytic fraction of telomerase (hTERT) by RT-PCR was used as a reference of the total amount of free DNA in blood.(More)
We studied a 62 year-old woman with a clinical phenotype characterized by encephalopathy, restrictive cardiomyopathy, and prominent intestinal pseudo-obstruction. Muscle morphology showed ragged red fibres with ultrastructurally abnormal mitochondrial whereas muscle respiratory chain was normal. Molecular genetics revealed the 'common deletion' in mtDNA,(More)
In May 2007, the Consorcio Hospital General Universitario de Valencia created the position of "Liaison Oncologist". The holder of this position is responsible for coordinating specialised and primary hospital care in the geographic area of Valencia known as Health Care Department 9 to reduce the waiting time between cancer diagnosis and treatment. In this(More)
AIM Telomeres are regions of highly repetitive, non-coding DNA located at the termini of chromosomes whose principal function is to maintain the structural stability of these ends. In 90% of human tumours, telomere length is maintained by the expression and activation of telomerase reverse transcriptase. Various studies have demonstrated an increase in(More)
Cancer is a high incidence disease, forcing healthcare systems to assign a significant amount of resources to its treatment. New developments have arisen recently: development of new agents that act at specific steps of cellular differentiation and proliferation and identification of predictive genetic markers which allow sub-groups of patients that will(More)
