BACKGROUND The prevalence of tic disorders in children varies from 1% to 29% depending on the characteristics of the study population, the diagnostic criteria, and the study design and methods. AIMS To calculate the prevalence of tic disorders among primary school children in Italy. METHODS The study population comprised 2347 primary school children from the city of Pavia (pop. 80 073), Nor...
Tics represent a complex class of behaviors that have a neurobiological origin and are influenced by factors both internal and external to the individual. One factor that has gained recent attention is the premonitory urge. Contemporary behavioral models suggest that some tics are preceded by aversive somatic urges that increase in severity when tics are suppressed and are attenuated by perform...
for some N. The only difficulty in the proof of these statements, beyond the methods already used in §§1-4, is the possibility that surfaces in $3 may have boundary values which are constant on some arcs of the circumference. Statement (1) yields a modified Morse theory; the usual requirement is that every k-cap contain a minimal surface g for which D [g] = a. But by assigning type numbers to b...
The vertebrate eye develops from apposed neural (op-tic vesicle) and surface (lens placode) ectoderm and its early development involves reciprocal inductive processes between these two tissues, both of which ex-Department of Biology press and require Pax6. In flies, a single ectodermal New York University epithelium forms both the retinal and lens components 1009 Main Bldg., 100 Washington Squa...
OBJECTIVES To determine whether juvenile obsessive-compulsive disorder (OCD) is familial and whether the rate of Tourette syndrome (TS) and tic disorders is higher among relatives of patients with OCD than among relatives of controls subjects. METHOD We assessed first-degree relatives of 35 juvenile OCD probands (aged 16 years or less) and 34 matched, psychiatrically unaffected control subjec...
Introduction: Stereotactically-guided core needle biopsies (CNB) of breast tumours allow histological examination of the tumour without surgery. Touch imprint cytology (TIC) of CNB promises to be useful in providing same-day diagnosis for counselling purposes and for planning future surgery. Having addressed the issue of accuracy of immediate microscopic evaluation of TIC, we wanted to re-exami...
Silicon has a high specific capacity of 4200 mAh/g as lithium-ion battery anodes, but its rapid capacity fading due to >300% volume expansion and pulverization presents a significant challenge for practical applications. Here we report a core-shell TiC/C/Si inactive/active nanocomposite for Si anodes demonstrating high specific capacity and excellent electrochemical cycling. The amorphous silic...
Web conferencing tools have entered the mainstream of business applications. Using web conferencing for IEEE conferences has a good potential of adding value to both organizers and participants. Authors propose a concept of Truly Integrated Conference (TIC) according to which a multi-point worldwide-distributed network of conference online authors/participants will enhance the standard (central...
Simulink has been used widely as an industry tool to model and simulate embedded systems. With increasing usage of embedded systems in real-time safety-critical situations, Simulink is deficient to cope with the requirements of high-level assurance and timing analysis. In this paper, we present a systematic approach to translate Simulink diagrams to Timed Interval Calculus (TIC), a notation ext...
Glioblastoma (GBM) harbors subpopulations of therapy-resistant tumor-initiating cells (TICs) that are self-renewing and multipotent. To understand the regulation of the TIC state, we performed an image-based screen for genes regulating GBM TIC maintenance and identified ZFHX4, a 397 kDa transcription factor. ZFHX4 is required to maintain TIC-associated and normal human neural precursor cell phe...
