In this study, Corynebacterium glutamicum and its derived mutants were used to demonstrate the relationship between proline, glutamate and ornithine. The maximum ornithine production was shown in the culture medium (3295.0 mg/l) when the cells were cultured with 20 mM proline and was 15.5 times higher than in the presence of 1 mM proline. However,(More)
BACKGROUND AND AIM Delayed post-polypectomy hemorrhage is a rare but serious complication. The aim of this study was to identify risk factors for the development of delayed post-polypectomy hemorrhage. METHODS This was a retrospective case-control study of patients who developed delayed hematochezia after receiving colonoscopic polypectomy. The control(More)
The primary determinant of influenza virus infectivity is the type of linkage between sialic acid and oligosaccharides on the host cells. Hemagglutinin of avian influenza viruses preferentially binds to sialic acids linked to galactose by an α-2,3 linkage whereas hemagglutinin of human influenza viruses binds to sialic acids with an α-2,6 linkage. The(More)
BACKGROUND Patients with bipolar disorder are at a high risk for becoming obese. Adipokines are associated with depression and obesity via the inflammatory process. However, few studies have investigated the associations between depression and leptin, adiponectin and resistin levels in patients with bipolar disorder. We explored the associations between(More)
A gene, phoI, coding for a phosphatase from Enterobacter sp. 4 was cloned in Escherichia coli and sequenced. Analysis of the sequence revealed one open reading frame (ORF) that encodes a 269–amino acid protein with a calculated molecular mass of 29 kDa. PhoI belongs to family B acid phosphatase and exhibits 49.4% identity and 62.4% homology to the hel gene(More)
Korean written language is composed of ideogram (Hanja) and phonogram (Hangul), as Japanese consists of Kanji (ideogram) and Kana (phonogram). Dissociation between ideogram and phonogram impairment after brain injury has been reported in Japanese, but few in Korean. We report a 64-yr-old right-handed man who showed alexia with agraphia in Hanja but(More)
AIM To identify the clinicopathological predictors of lymph node (LN) metastasis and evaluate the outcomes of endoscopic submucosal dissection (ESD) in papillary adenocarcinoma-type early gastric cancers (EGCs). METHODS From January 2005 to May 2013, 49 patients who underwent surgical operation and 24 patients who underwent ESD for papillary(More)
BACKGROUND Metabolic engineering of cyanobacteria has enabled photosynthetic conversion of CO2 to value-added chemicals as bio-solar cell factories. However, the production levels of isoprenoids in engineered cyanobacteria were quite low, compared to other microbial hosts. Therefore, modular optimization of multiple gene expressions for metabolic(More)
The principal objective of this study was to compare the effects of whole and hydrolyzed cells (bifidobacteria) treated with gastrointestinal digestive enzymes on the activation of cloned macrophages. Seven different strains of Bifidobacterium obtained from swine, chickens, and rats, were digested with pepsin followed by pancreatin and the precipitate(More)
A nephropathogenic K2/01 strain of infectious bronchitis virus (IBV) was attenuated by 170 serial passages in embryonated chicken eggs for possible use as a future IBV vaccine strain. High-growth properties and narrow tissue tropisms (limited replication in respiratory tracts) were achieved by the adaptation process. Unlike the parent strain, the attenuated(More)
