UNLABELLED The present study compared the ability of 12 people who stutter (PWS) and 12 people who do not stutter (PNS) to consolidate a novel sequential speech task. Participants practiced 100 repetitions of a single, monosyllabic, nonsense word sequence during an initial practice session and returned 24-h later to perform an additional 50 repetitions. Results showed significantly slower seque...

Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are oppositely imprinted autism-spectrum disorders with known genetic bases, but complex epigenetic mechanisms underlie their pathogenesis. The PWS/AS locus on 15q11-q13 is regulated by an imprinting control region that is maternally methylated and silenced. The PWS imprinting control region is the promoter for a one megabase paternal trans...

Prader-Willi syndrome (PWS) is a rare neurogenetic disorder, which occurs in l per 15,000 live-born children. First described in 1956 by doctors Prader, Labhart and Willi, it is the commonest cause of syndromic obesity in childhood. Diabetes mellitus (DM) is a rare complication of children with PWS. A literature search revealed that most PWS children with DM have required insulin as their treat...

We apply phase-weighted stacking (PWS) to the analysis of lowfrequency earthquakes (LFEs) in the Parkfield, California, region and central Cascadia. The technique uses the coherence of the instantaneous phase among the stacked signals to enhance the signal-to-noise ratio (SNR) of the stack. We find that for picking LFE arrivals for the Parkfield, California, region and for LFE template formatio...

BACKGROUND Thermoregulation problems, resulting in hypo- or hyperthermia, have been infrequently reported in children with Prader Willi syndrome (PWS), yet their clinical details remained unknown. METHODS The clinical characteristics of three infants with PWS are reported. RESULTS Etiologies of high fever could not be identified in three children with PWS. One of these children was also adm...

Prader-Willi syndrome (PWS) is characterized by infantile lethargy and hypotonia causing poor feeding and failure to thrive, childhood obesity, short stature, and hypogonadism. The complex phenotype is most probably caused by a hypothalamic dysfunction that is responsible for the hormonal dysfunction. The resulting hypogonadism in PWS causes incomplete, delayed, and sometimes disordered puberta...

CONTEXT Prader-Willi syndrome (PWS) is characterized by severe hyperphagia. Brain-derived neurotrophic factor (BDNF) and leptin are reciprocally involved in energy homeostasis. OBJECTIVES To analyze the role of BDNF and leptin in satiety in genetic subtypes of PWS. DESIGN Experimental study. SETTING University hospital. SUBJECTS 90 adults: 30 PWS patients; 30 age-sex-BMI-matched obese c...

The gastrointestinal effects of intraluminal fats may be critically dependent on the chain length of fatty acids released during lipolysis. We postulated that intraduodenal administration of lauric acid (12 carbon atoms; C12) would suppress appetite, modulate antropyloroduodenal pressure waves (PWs), and stimulate the release of cholecystokinin (CCK) and glucagon-like peptide-1 (GLP-1) more tha...

CONTEXT Narcoleptic patients with cataplexy have a general loss of hypocretin (orexin) in the lateral hypothalamus, possibly due to an autoimmune-mediated degeneration of the hypocretin neurons. In addition to excessive daytime sleepiness, Prader-Willi syndrome (PWS) patients may show narcolepsy-like symptoms, such as sleep-onset rapid eye movement sleep and cataplexy, independent of obesity-re...

Pyungwi-san (PWS) is a traditional basic herbal formula. We investigated the effects of PWS on induction of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), pro-inflammatory cytokines (interleukin-6 (IL-6) and tumor necrosis factor- α (TNF- α )) and nuclear factor-kappa B (NF- κ B) as well as mitogen-activated protein kinases (MAPKs) in lipopolysaccharide-(LPS-) induced Raw 264...
