A fuel cell was used to enrich a microbial consortium generating electricity, using organic wastewater as the fuel. Within 30 days of enrichment the maximum current of 0.2 mA was generated with a resistance of 1 kΩ. Current generation was coupled to a fall in chemical oxygen demand from over 1,700 mg l−1 down to 50 mg l−1. Denaturing gradient gel(More)
Many of the effects of resveratrol are consistent with the activation of AMP-activated protein kinase (AMPK), silent information regulator T1 (SIRT1) and peroxisome proliferator-activated receptor (PPAR)γ co-activator 1α (PGC-1α), which play key roles in the regulation of lipid and glucose homeostasis, and in the control of oxidative stress. We investigated(More)
While pleural effusion in multiple myeloma is relatively infrequent, myelomatous pleural effusion is extremely rare. We experienced a 61-year-old woman with IgD-lambda multiple myeloma and pleural effusion. The diagnosis was made originally by pleural biopsy, pleural fluid cytology and immunoelectropheresis of pleural fluid. Transient improvement of the(More)
In some patients, eosinophilic gastroenteritis(EG) occurs in those with food allergy. We experienced a non-atopic asthmatic who had an EG associated with food allergy to fish and eggs, and blood eosinophilia. A skin prick test and RAST to causative food allergens showed a negative result. A fiber-optic endoscopic biopsy from the gastric mucosa showed an(More)
Toluene diisocyanate (TDI) is the most prevalent agent in occupational asthma (OA) in Korea. The immuno-pathologic mechanism for TDI-induced bronchoconstriction remains to be clarified. We studied the immunohistochemical finding of inflammatory cells in bronchial mucosa in subjects with TDI-induced asthma. Fiberoptic bronchial biopsy specimens were obtained(More)
Translation of the polycistronic 35S RNA of CaMV (cauliflower mosaic virus) occurs via a reinitiation mechanism, which requires TAV (transactivator/viroplasmin). To allow translation reinitiation of the major open reading frames on the polycistronic RNA, TAV interacts with the host translational machinery via eIF3 (eukaryotic initiation factor 3) and the(More)
Isocyanate is the most prevalent agent in occupational asthma(OA) in Korea. We analyzed 43 toluene diisocyanate(TDI) induced OA patients of whom 81% were found to be spray painters. The bronchial sensitivity of all subjects was confirmed by TDI-bronchial challenge test. Serum-specific IgE antibodies to isocyanate-human serum albumin(HSA) conjugate were(More)
BACKGROUND AND OBJECTIVE Persistent asthma symptoms are associated with airway inflammation and remodeling, which may be mediated through metalloproteinase (MMP) and tissue inhibitor of metalloproteinase (TIMP). The aim of this study was to evaluate MMPs and TIMP involvement in toluene diisocyanate (TDI)-induced asthma. MATERIALS AND METHOD Induced sputum(More)
Porcine pancreatic extracts (PPE) are composed of alpha-amylase and lipase, which are common components of digestive enzymes. They have been known to cause occupational asthma in exposed workers in pharmaceutical and baking industries, as well as in a laboratory technician, but there has been no report of PPE-induced occupational asthma in medical personnel(More)
