Anaphylaxis is a life-threatening systemic allergic reaction with the potential for a recurrent or biphasic pattern. Despite an incidence of biphasic reaction between 5 and 20%, the molecular mechanism for the reaction is unknown. Using a murine model of penicillin V-induced systemic anaphylaxis, we show an autoregulatory cascade of biphasic anaphylactic(More)
Cilia are microtubule-based structures that project into the extracellular space. Ciliary defects are associated with several human diseases, including polycystic kidney disease, primary ciliary dyskinesia, left-right axis patterning, hydrocephalus and retinal degeneration. However, the genetic and cellular biological control of ciliogenesis remains poorly(More)
OBJECTIVE It has been shown that Mindbomb (Mib), an E3 Ubiquitin ligase, is an essential modulator of Notch signaling during development. However, its effects on vascular development remain largely unknown. APPROACHES AND RESULTS We identified a number of novel proteins that physically interact with Mib, including the Factor Inhibiting Hypoxia Inducible(More)
XB51 protein is known to interact with the amino-terminal of the X11L protein and to be involved in Abeta40 generation, a hallmark of Alzheimer's disease. In this study, we isolated a zebrafish xb51 homologue and analyzed its spatio-temporal expression pattern during early brain development. The xb51 transcript was first detected in the forebrain at 22 hr(More)
Miles-Carpenter syndrome (MCS) was described in 1991 as an XLID syndrome with fingertip arches and contractures and mapped to proximal Xq. Patients had microcephaly, short stature, mild spasticity, thoracic scoliosis, hyperextendable MCP joints, rocker-bottom feet, hyperextended elbows and knees. A mutation, p.L66H, in ZC4H2, was identified in a XLID(More)
Middle East Respiratory Syndrome (MERS) is an acute viral respiratory illness with high mortality caused by a new strain of betacoronavirus (MERS-CoV). Since the report of the first patient in Saudi Arabia in 2012, large-scale outbreaks through hospital-acquired infection and inter-hospital transmission have been reported. Most of the patients reported in(More)
OBJECTIVE To investigate improved dysphagia after the decannulation of a tracheostomy in patients with brain injuries. METHODS The subjects of this study are patients with brain injuries who were admitted to the Department of Rehabilitation Medicine in Myongji Hospital and who underwent a decannulation between 2012 and 2014. A video fluoroscopic(More)
