A map of 191 single-nucleotide polymorphism (SNPs) was built across a 5-Mb segment from chromosome 13q34 that has been genetically linked to schizophrenia. DNA from 213 schizophrenic patients and 241 normal individuals from Canada were genotyped with this marker set. Two 1,400- and 65-kb regions contained markers associated with the disease. Two markers(More)
Tetrodotoxin-resistant (TTX-R) sodium currents have been proposed to underlie sensory neuronal hyperexcitability in acute inflammatory models, but their role in chronic models is unknown. Since no pharmacological tools to separate TTX-R currents are available, this study employs Na(v)1.8 and Na(v)1.9 null mice to evaluate these currents roles in a chronic(More)
Administration of specific drugs may occasionally induce acquired long QT syndrome (aLQTS), a disorder that predisposes to ventricular arrhythmias, typically of the torsade de pointes (TdP) type, and sudden cardiac death. "Forme fruste" mutations in congenital LQTS (cLQTS) genes have been reported repeatedly as the underlying cause of aLQTS, and are(More)
OBJECTIVE Mutations in the KCNH2 (hERG, human ether-à-go-go related gene) gene may cause a reduction of the delayed rectifier current I(Kr), thereby leading to the long QT syndrome (LQTS). The reduced I(Kr) delays the repolarisation of cardiac cells and renders patients vulnerable to ventricular arrhythmias and sudden death. We identified a novel mutation(More)
UNLABELLED Polymorphisms of the IL28B gene are highly associated with sustained virological response (SVR) in patients with chronic hepatitis C treated with peginterferon and ribavirin. Quantitation of interferon-γ-inducible protein-10 (IP-10) may also differentiate antiviral response. We evaluated IP-10 levels in pretreatment serum from 115 nonresponders(More)
Apolipoprotein E (APOE) has been extensively demonstrated to be a genetic risk factor for Alzheimer's disease (AD). Associations of APOE genotype have been reported with age at AD onset, rate of decline, and responsiveness to therapy. This study aimed to test these hypotheses in a large study population of AD patients. APOE genotype was determined from(More)
Nandrolone decanoate (ND) is an anabolic steroid with a positive effect on bone mass in osteoporotic patients. The mechanism of action, (i.e., reduction of bone resorption and/or Stimulation of bone formation), the ultimate effect on mechanical properties, and the most effective dosage are not yet clear. To address these issues, dose-related effects of the(More)
Ultra-deep sequencing (UDS) of amplicons is a major application for next-generation sequencing technologies, even more so for the 454 Genome Sequencer FLX. Especially for this application, errors that might be introduced during any of the sample processing or data analysis steps should be avoided or at least recognized, as they might lead to aberrant(More)
Both a decrease in bone formation and an increase in bone resorption have been implicated in the pathogenesis of age-related (type II) femoral neck osteoporosis. While the increase in the bone resorption rate has been shown to be partially related to secondary hyperparathyroidism, the mechanisms underlying the decline in bone formation have not yet been(More)
In view of the reported associations between osteoporosis and polymorphisms of the vitamin D receptor (VDR), collagen Ialpha1 (COLIA1) and estrogen receptor (ER) genes, an association study was performed between VDR, COLLIA1, and ER genotypes and bone mineral density, biochemical markers of bone turnover and hip fracture occurrence in Belgian older(More)
