Constitutive and PKC-regulated alpha-secretase pathways have been reported to produce the secreted form of alpha-secretase-derived APP (sAPPalpha). Here, we examined putative role of furin in the regulation of alpha-secretase activity in vitro and in vivo. Overexpression of the prodomain of furin and infection with a furin-specific inhibitor significantly(More)
BACKGROUND In 2015, a large outbreak of Middle East respiratory syndrome coronavirus (MERS-CoV) infection occurred following a single patient exposure in an emergency room at the Samsung Medical Center, a tertiary-care hospital in Seoul, South Korea. We aimed to investigate the epidemiology of MERS-CoV outbreak in our hospital. METHODS We identified all(More)
The Uba6-Use1 ubiquitin enzyme cascade is a poorly understood arm of the ubiquitin-proteasome system required for mouse development. Recently, we reported that Uba6 brain-specific knockout (termed NKO) mice display abnormal social behavior and neuronal development due to a decreased spine density and accumulation of Ube3a and Shank3. To better characterize(More)
Interferon-gamma (IFN-gamma) is a pleiotropic cytokine produced by T cells and natural killer cells that has been implicated as a deleterious factor in the immune-mediated demyelinating disorder multiple sclerosis. In vitro, purified developing and mature oligodendrocytes have been shown to die in the presence of IFN-gamma by apoptosis and necrosis,(More)
Adefovir dipivoxil (ADV) is a nucleotide used as long-term therapy of chronic hepatitis B. Many published reports have shown that long-term high-dose therapy with adefovir can be associated with proximal renal tubular dysfunction resulting in significant hypophosphatemia, renal insufficiency and osteomalacia. We have encountered two patients who developed(More)
BACKGROUND Postoperative nausea and vomiting (PONV) frequently develops in patients undergoing thyroidectomy, and propofol-based total intravenous anesthesia (TIVA) has been reported to reduce the incidence of PONV. The present study was undertaken to compare the effects of ramosetron on PONV in women following total thyroidectomy under TIVA. METHODS One(More)
BACKGROUND Propofol and barbiturates are both known to protect cells of several organs against ischemia/reperfusion injury, but there are few reports on any possible protective effects on human hepatocytes. We investigated the activities of both agents on human hepatic SNU761 cells under hydrogen peroxide (H(2)O(2))-induced oxidative stress. METHODS To(More)

We conducted in-depth interviews with 11 Korean Disaster Relief Team (KDRT) members about stress related to disaster relief work and analyzed the interview data using the Consensual Qualitative Research (CQR) method in order to evaluate difficulties in disaster relief work and to develop solutions to these problems in cooperation with related organizations.(More)
BACKGROUND Mild hypercapnia is permitted during surgeries in sitting position under general anesthesia to maintain cerebral regional oxygen saturation (rSO2). However, since hypoventilation may cause gas exchange impairment, we evaluated effects of mild hypercapnia on lung oxygenation during shoulder arthroscopy in sitting position.
