It has been suggested that psychosocial stress influences situational fluctuations of tic frequency. However, evidence from experimental studies is lacking. The current study investigated the effects of the Trier Social Stress Test (TSST-C) on tic frequency in 31 children and adolescents with tic disorders. A relaxation and a concentration situation served as control conditions. Patients were a...
Although tumor-initiating cell (TIC) self-renewal has been postulated to be essential in progression and metastasis formation of human pancreatic adenocarcinoma (PDAC), clonal dynamics of TICs within PDAC tumors are yet unknown. Here, we show that long-term progression of PDAC in serial xenotransplantation is driven by a succession of transiently active TICs producing tumor cells in temporally ...
Exposure with response prevention versus habit reversal in Tourettes's syndrome: a controlled study.
The intentional nature of tics provides the opportunity to apply behavioural interventions aimed at tic reduction through interruption of stimulus-response sequences. The aim of this study has been to evaluate the effect of exposure and response prevention (ER) versus habit reversal (HR) in 43 Tourette's syndrome (TS) patients. The three outcome measures were: the Yale Global Tic Severity Scale...

introduction: until now, many models have been presented for optical study of the human eye. in recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. material and methods: in this article, some of these models are considered. they incl...
PREVIOUS STUDIES HAVE SHOWN that for each rapid eye movement of lowvoltage fast sleep there is a corresponding monophasic wave of 100-140 msec. in the lateral geniculate body of the cat (8). These waves do not depend upon the presence of the retina or the eye muscle afferents (5, 22). In fact, follow ,ing either retinal photocoagulation of the optic disc or enucleation of the eyes, these genicu...
Background: Sports vision is a specialisation of optometry whose objective to improve and preserve visual function increase sports performance. The main the present study was compare expertise non-athletes skeet shooting athletes. Methods: Participants underwent an optometric assessment in which all those with severe deviations from normal vision, after compensating for abnormalities, were elim...
Blepharospasm is an uncontrolled spasmodic contraction of the orbicularis muscles of the eye resulting in an abnormal tic or twitch of eyes. It usually lasts for seconds to minutes but in severe cases eyes may be closed for hours. It may be essentially benign or secondary due to a lesion in basal ganglia, pyramidal tract, and trauma, local pathology in the eyes or drug induced. Here we are pres...
BACKGROUND The time-signal intensity curve (TIC) of the pancreas obtained from dynamic contrast-enhanced magnetic resonance imaging closely reflects the histological degree of pancreatic fibrosis. MATERIALS AND METHODS Seventy-six patients who had undergone a pancreatic TIC analysis prior to receiving a pancreaticoduodenectomy for various reasons were subjected to a yearly monitoring with pan...
