Congenital diseases of dysmotility are a serious problem in children and, potentially, also in adults. Advances have recently been made in understanding one cause of pediatric dysmotility, Hirschsprung’s disease, which is the most visible congenital defect of the enteric nervous system (ENS). Although the diagnosis of Hirschsprung’s disease is sometimes missed, and the length of involved gut ma...

The spotting lethal rat, a naturally occurring rodent model of Hirschsprung disease, carries a deletion in the endothelin-B receptor (EDNRB) gene that abrogates expression of functional EDNRB receptors. Rats homozygous for this mutation (sl) exhibit coat color spotting and congenital intestinal aganglionosis. These deficits result from failure of the neural crest-derived epidermal melanoblasts ...

As we enter the 21 century, the segment of the population that is the most rapidly expanding is that comprised of individuals 85 years of age and older. Dysfunctions of the gastrointestinal (GI) system, including dysphagia, constipation, diarrhea, and irritable bowel syndrome are more common complaints of the elderly, yet our knowledge of the aging GI tract is incomplete. Compared to the rapid ...

The Entity Name System (ENS) is a service aiming at providing globally unique URIs for all kinds of real-world entities such as persons, locations and products, based on descriptions of such entities. Because entity descriptions available to the ENS for deciding on entity identity—Do two entity descriptions refer to the same real-world entity?—are changing over time, the system has to revise it...

A major challenge in e-negotiation systems (ENS) is that the context of negotiation such as negotiators’ characteristics, negotiation processes and system support varies in each case. This context dependency makes it difficult to apply a single ENS to a wide variety of negotiations. In this paper, to mitigate the context dependency issue, we propose to adopt the componentoriented approach and t...

Emergency nurses (ENs) typically place peripheral intravenous (IV) lines, but if repeated attempts fail, patients usually receive central line access. To measure the effect of ultrasound (US) guidance on the perceived difficulty of EN peripheral IV access in Emergency Department patients, a prospective observational study was conducted of ENs in a level I trauma center with a census of 75,000, ...
