Glutaric aciduria type I (GA I) is an autosomal recessive disorder caused by a deficiency of glutaryl-CoA dehydrogenase. Although over 400 patients confirmed as GA I have been reported, reports from the Asian population had contributed to the minor proportion. We recently diagnosed two cases of GA I confirmed with mutational analysis. Here, we present their(More)
In this paper, a metrology method is presented to calibrate modular robots. It is to perform metrology at the modular level and measure the kinematic parameters of each module so that the acquired information may be used for obtaining an "as built" model every time either a modular robot is reconfigured or maintenance has been made. Based on the(More)
Aluminum hydroxide (alum) is the most widely used adjuvant in human vaccines. Nevertheless, it is virtually unknown whether alum acts on B cells. In the present study, we explored the direct effect of alum on Ig expression by murine B cells in vitro. LPS-activated mouse spleen B cells were cultured with alum, and the level of isotype-specific Ig secretion,(More)
OBJECTIVE The aim of this study was to characterize the SCN1A mutation spectrum in Korean patients with Dravet syndrome. METHODS Twenty-nine patients diagnosed with Dravet syndrome at the Seoul National University Children's Hospital were included in the study. Direct sequencing and multiplex ligation-dependent probe amplification (MLPA) were used to(More)
In this study, data from a pandemic H1N1 outbreak in Korea were analyzed according to time, geography (districts), and age. A total of 252,271 samples collected nationwide were referred to the Greencross Reference Laboratory from June 2009 to February 2010 for H1N1 confirmation testing. Of these samples, 105,300 (41.7%) were H1N1-positive. With time,(More)
Hereditary spastic paraplegia (HSP) is a genetically heterogeneous group of diseases characterized by insidiously progressive lower-extremity weakness and spasticity. Spastic paraplegia 4 (SPAST) is the most common type of uncomplicated autosomal dominant HSP (40% of such cases), and spastic paraplegia 3A (ATL1) is the second most common. Here, we conducted(More)
BACKGROUND APOE ɛ4 contributes to Alzheimer's disease (AD) pathogenesis by amyloid-beta (Aβ)-dependent and Aβ-independent processes. OBJECTIVE We investigated the APOE ɛ4 influence on regional cerebral glucose metabolism (rCMglc) in the continuum of AD after Aβ adjustment. METHODS We included 318 cognitively normal (CN) elderly, 498 mild cognitive(More)
Platelets are essential for progression of atherosclerotic lesions, plaque destabilization, and thrombosis. They secrete and express many substances that are crucial mediators of coagulation, inflammation, and atherosclerosis. Mean platelet volume (MPV) is a precise measure of platelet size, and is routinely reported during complete blood count analysis.(More)
BACKGROUND Papillary thyroid carcinoma (PTC) is frequently accompanied by lymphocytic thyroiditis (LT). Some reports claim that Hashimoto's thyroiditis (the clinical form of LT) enhances the likelihood of PTC; however, others suggest that LT has antitumor activity. This study was aimed to find out the relationship between the patterns of helper T cell (Th)(More)
