We investigated the light reactions, CO2 assimilation, but also the chloroplast ultrastructure in the upper three functional leaves (flag, 2nd, and 3rd leaves) of the Chinese super-high-yield hybrid rice (Oryza sativa L.) Liangyoupeijiu (LYPJ) with ultraviolet-B (UV-B) treatment during reproductive development. Photosynthetic parameters showed that the(More)
PURPOSE To evaluate percutaneous transluminal forceps biopsy in patients suspected of having a malignant biliary obstruction. MATERIALS AND METHODS One hundred thirty consecutive patients (82 men and 48 women; mean age, 59 years) with obstructive jaundice underwent transluminal forceps biopsy during or after percutaneous transhepatic biliary drainage. The(More)
UNLABELLED Clevudine is a pyrimidine analog with potent and sustained antiviral activity against HBV. In the present study, we evaluated the safety and efficacy of clevudine 30 mg daily for 24 weeks and assessed the durability of antiviral response for 24 weeks after cessation of dosing in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (e-CHB).(More)
UNLABELLED Clevudine is a pyrimidine analogue with potent and sustained antiviral activity against HBV. The present study evaluated the safety and efficacy of 30 mg clevudine once daily for 24 weeks and assessed the durable antiviral response for 24 weeks after cessation of dosing. A total of 243 hepatitis B e antigen (HBeAg)-positive chronic hepatitis B(More)
The effects of sedative peptide alkaloids from Zizyphus species on calmodulin- dependent protein kinase II were investigated. Protein kinase II activity was assayed on the basis of its ability to activate tryptophan 5-monooxygenase as its substrate in the presence of calmodulin. All thirteen alkaloids tested were stronger inhibitors than chlorpromazine(More)
To evaluate and compare the therapeutic efficacy of adenine arabinoside (Ara-A) and alpha-interferon (alpha-INF), 40 patients with biopsy proven chronic active hepatitis B were chosen at random to receive Ara-A (15 mg/Kg, iv, for 10 day) or alpha-INF (3 million unit, sc, every other day for 12 wks) and followed up to 12 months after completion of the(More)
We introduce some simulation and experiment results of the multichannel magnetic stimulator development that has been carried out as an initial attempt to realize a multichannel functional magnetic stimulator. For efficient functional magnetic stimulations, precise spatial localization of stimulation sites without any movements of the stimulation coils is(More)
Magnetic steering of an untethered ferromagnetic device in a living body has many advantages in the clinical fields. In this paper, the positioning and tracking methods of a ferromagnetic sphere have been compared with magnetic resonance phantom images obtained with three different imaging sequences, spin echo, gradient echo, and selected positive contrast(More)
We report the first description of a new integron containing bla(VIM-2), a metallo-beta-lactamase gene from Enterobacter cloacae KU680, which was isolated from peritoneal fluid of a liver cirrhosis patient in South Korea. Antibiotic susceptibility testing, and modified Hodge and EDTA-disc synergy tests, were carried out to screen for(More)
This study was conducted to evaluate the durability of clevudine-induced viral response after the withdrawal of treatment. Patients who showed a complete response [alanine aminotransferase (ALT) normalization and hepatitis B virus (HBV) DNA <4,700 copies/mL for hepatitis B envelope antigen (HBeAg)-negative patients; ALT normalization, HBV DNA <4,700(More)
