BACKGROUND The contribution of the metal components of particulate pollutants to acute respiratory effects has not been adequately evaluated. Moreover, little is known about the effects of genetic polymorphisms of xenobiotic metabolism on pulmonary function. OBJECTIVES This study was conducted to assess lung function decrement associated with metal(More)
BACKGROUND/AIMS There has been a controversy regarding the usefulness of biofeedback therapy for functional constipation or fecal incontinence. This study was performed to investigate the long-term clinical efficacy of biofeedback therapy. METHODS Sixty-four patients with constipation or fecal incontinence received biofeedback therapy for 4 weeks. Symptom(More)
This paper describes development of an inverse building model and its application in studying the performance of a demand-limiting (DL) control strategy. The demand-limiting strategy involves precooling (PC) a building during unoccupied times, maintaining the zone temperature setpoints at the lower limit of comfort during off-peak, occupied periods, and(More)
Accurate network topology information can play very important role in a network management system. Discovering network topology is a prerequisite for many critical network management tasks including reactive and proactive resource management, fault management, and root-cause analysis. Unfortunately, the equipment managed in an NMS includes switches as well(More)
Tumor necrosis factor (TNF)-alpha induces pleiotropic cellular effects through a 55kDa, type 1 receptor (TNFR1) and a 75kDa type 2 receptor (TNFR2). Moreover, it participates in the pathogenesis of several CNS diseases, including demyelinating diseases. TNF-alpha receptors are differentially expressed and are regulated in many cell types. However, data(More)
Chronic intestinal pseudo-obstruction (CIPO) is a rare disorder characterized by a severe impairment of gastrointestinal propulsion in the absence of mechanical obstruction. We experienced a case of chronic pseudo-obstruction in the initial phase mimicking acute pseudo-obstruction, which was treated medically. This ongoing case was compared to another(More)
