Prader-Willi syndrome (PWS) is a rare genetic disorder reported rarely in dentistry. Dental practitioners should know the features of PWS because affected patients have a variety of dental symptoms. The current report describes a case of PWS. An 18-year-old male patient presented with traumatic injuries. Initial emergency treatments were performed under sedation, and further treatments were con...

Angelman syndrome (AS) and Prader-Willi syndrome (PWS) are distinct human neurogenetic disorders; however, a clinical overlap between AS and PWS has been identified. We report on a further case of a patient showing the PWS phenotype with the AS molecular defect. Despite the PWS phenotype, the DNA methylation analysis of SNRPN revealed an AS pattern. Cytogenetic and FISH analysis showed normal c...

Prader-Willi syndrome (PWS) is an unusual, rare complex autosomal neurodevelopmental disease resulting from genomic imprinting and uniparental disomy of maternal chromosome 15 with a simultaneous functional loss of the parental part 15q11.2-q13. This article briefly elucidates the phenomenon of genomic imprinting, focuses on the diverse clinical features of PWS and concludes with the management...

BACKGROUND AND OBJECTIVE Port wine stains (PWS) are heterogeneous vascular malformations that can be treated with vascular-selective pulsed dye lasers (PDL). Hypertrophic PWS, especially in adults, are consistently less responsive to PDL. Furthermore, many PWS that respond well initially to PDL treatment may reach a response plateau, becoming unresponsive to further PDL treatments, a phenomenon...

abstract Pattern-weight pairs (pws) are a new form of search and planning knowledge. Pws are predicates over states coupled with a least upper bound on the distance from any state satisfying that predicate to any goal state. The relationship of pws to more traditional forms of search knowledge is explored with emphasis on macros and subgoals. It is shown how pws may be used to overcome some of ...

PURPOSE Amylin secretion is increased parallel to insulin in obese subjects. Despite their marked obesity, a state of relative hypoinsulinemia occurs in children with Prader-Willi syndrome (PWS). Based on the hypothesis that amylin levels may be relatively low in PWS children, contributing to their excessive appetite, we studied amylin levels after oral glucose loading in children with PWS and ...

Prader-Willi syndrome (PWS) is a complex neurogenetic disorder. The phenotype is likely to be a contiguous gene syndrome involving genes which are paternally expressed only, located in the human 15q11-q13 region. Four mouse models of PWS have been reported but these do not definitively allow the delineation of the critical region and the associated genes involved in the aetiology of PWS. Moreov...

OBJECTIVE Prader-Willi syndrome (PWS), the leading known genetic cause of obesity, is characterized by intellectual disabilities, maladaptive and compulsive behaviors, and hyperphagia. Although complications of obesity resulting from hyperphagia are the leading cause of death in PWS, quantifying this drive for food has long been an unmet research need. This study provides factor-analytic and wi...

Peripheral waves (PWs) in the channel catfish are odorant-induced neural oscillations of synchronized populations of olfactory receptor neurons (ORNs) that appear after the initial approximately 500 msec of the response. The mean dominant frequency during the initial 2 sec of PW activity is approximately 28 Hz, declining to approximately 20 Hz in the last sec of a 5 sec stimulus. Recordings of ...
