Tics in Gilles de la Tourette syndrome (GTS) resemble fragments of normal motor behaviour but appear in an intrusive, repetitive and context-inappropriate manner. Although tics can be voluntarily inhibited on demand, the neural correlates of this process remain unclear. 14 GTS adults without relevant comorbidities participated in this study. First, tic severity and voluntary tic inhibitory capa...

The present work studies the synthesis and performance of TiC/H13 tool steel composite coatings obtained by the laser deposition technique. he effect of laser beam-scanning speeds and the concentrations of TiC in injected powder on the morphologies and microstructures of deposited eads are investigated. The results show that the beam-scanning speeds affect the size and morphology of the beads. ...

BACKGROUND Dilated cardiomyopathy (DCM) involves significant remodeling of the left ventricular-mitral valve (MV) complex, but little is known regarding the remodeling of the mitral leaflets. The aim of this study was to assess changes in matrix composition and turnover in MV leaflets with DCM. METHODS AND RESULTS Radiopaque markers were implanted in 24 sheep to delineate the MV; 10 sheep und...

Glioblastoma (GBM) is maintained by a small subpopulation of tumor-initiating cells (TICs). The arduous assessment of TIC frequencies challenges the prognostic role of TICs in predicting the clinical outcome in GBM patients. We estimated the TIC frequency in human GBM injecting intracerebrally in mice dissociated cells without any passage in culture.All GBMs contained rare TICsand were tumorige...

BACKGROUND Medical costs of (psychiatric) illness can be validly measured with patient report questionnaires. These questionnaires comprise many detailed items resulting in lengthy administrations. OBJECTIVES We set out to find the minimal number of items needed to retrieve 80% and 90% of the costs as measured by the Treatment Inventory of Costs in Patients with psychiatric disorders (TIC-P)....

EMG was recorded in nine subjects suffering from chronic tic disorder. Six subjects suffered asymmetrical tics and three had symmetrical tics. EMG in tic-affected and contralateral nonaffected sites was recorded at rest, during a baseline period, and at postbiofeedback training. All subjects received 2-4 biofeedback training sessions aimed at enhancing their ability to control levels of muscle ...

This study sought to examine quality of life (QoL) in clinic-referred children and adolescents (n = 59, M age = 11.4+/-2.6 years) with a chronic tic disorder. The QoL scores for tic patients were lower than for healthy controls but higher than for the psychiatric sample on the majority of domains. Children's self-reported QoL scores and a measure of tic severity were moderately and inversely co...

Seventy-six people (aged 18-62 years) diagnosed with either a chronic tic disorder or a habit disorder, entering a treatment study, kept a baseline daily diary for at least ten days, noting tic frequency and activity at time of onset. Together with an evaluator, participants completed a form ranking three high-risk activities where the tic or habit was likely to appear, and three low-risk activ...

The present study analyzed rates of peer victimization in children with a chronic tic disorder as compared to children with type 1 diabetes and healthy controls. The associations among peer victimization, tic symptom severity, and psychological symptoms, as well as the potential mediating relationship between peer victimization, tic severity, and child internalizing symptoms, were also explored...

Pharmacological and behavioral interventions have focused on reducing tic severity to alleviate tic-related impairment for youth with chronic tic disorders (CTDs), with no existing intervention focused on the adverse psychosocial consequences of tics. This study examined the preliminary efficacy of a modularized cognitive behavioral intervention ("Living with Tics", LWT) in reducing tic-related...
