Stimulation of various cells with growth factors results in a transient increase in the intracellular concentration of H2O2 that is required for growth factor-induced protein tyrosine phosphorylation. The effect of H2O2 produced in response to epidermal growth factor (EGF) on the activity of protein-tyrosine phosphatase 1B (PTP1B) was investigated in A431(More)
Previous evidence has indicated that the neuronal toxicity of amyloid beta (betaA) protein is mediated through oxygen free radicals and can be attenuated by antioxidants and free radical scavengers. Recent studies have shown that green tea polyphenols reduced free radical-induced lipid peroxidation. The purpose of this study was to investigate whether(More)
OBJECTIVES To investigate the clinical characteristics and outcomes of Takayasu's arteritis (TA) using standardized criteria for diagnosis, disease activity, and angiographic classification, and to identify the predictive factors for remission, angiographic progression, and mortality in patients with TA. METHODS One hundred and eight patients who(More)
Gastrodia elata (GE) has been used traditionally for the treatment of convulsive diseases such as epilepsy in oriental countries including South Korea and still occupies an important place in traditional medicine in Asia. We studied the anticonvulsive effect and protective effect of the ether fraction of methanol extracts (EFME) of GE against hippocampal(More)
A procedure for detecting proteins that contain H(2)O(2)-sensitive cysteine (or selenocysteine) residues was developed as a means with which to study protein oxidation by H(2)O(2) in cells. The procedure is based on the facts that H(2)O(2) and biotin-conjugated iodoacetamide (BIAM) selectively and competitively react with cysteine residues that exhibit a(More)
A thioredoxin reductase (TrxR), named here TrxR2, that did not react with antibodies to the previously identified TrxR (now named TrxR1) was purified from rat liver. Like TrxR1, TrxR2 was a dimeric enzyme containing selenocysteine (Secys) as the COOH-terminal penultimate residue. A cDNA encoding TrxR2 was cloned from rat liver; the open reading frame(More)
OBJECTIVES Nuclear factor kappa B (NF-kappaB) is a major regulator of pivotal proinflammatory cytokines in the pathogenesis of rheumatoid arthritis (RA). Bortezomib inhibits NF-kappaB activation by blocking the degradation of the NF-kappaB inhibitor, I-kappaB. In this study, the efficacy of bortezomib on murine collagen-induced arthritis (CIA) was(More)
To investigate whether the ratio of mitral peak velocity of early filling (E) to early diastolic mitral annular velocity (E') (E/E' ratio) can detect left ventricular diastolic dysfunction more sensitively than the ratio of E to mitral peak velocity of late filling (A) (E/A ratio) in systemic lupus erythematosus (SLE). A total of 137 patients with SLE were(More)
OBJECTIVE To investigate the prognostic value of metabolic tumour volume (MTV) and total lesion glycolysis (TLG), measured by preoperative positron emission tomography and computerised tomography (PET/CT), in women with endometrial cancer. DESIGN Retrospective cohort study. SETTING A tertiary referral centre. POPULATION Women with endometrial cancer(More)
UNLABELLED The aim of this study is to evaluate the usefulness of (18)F-FDG PET/CT for preoperative stratification of high-risk and low-risk carcinomas in patients with endometrial cancer. PATIENTS, METHODS 60 women (mean age 53.8±9.9 years) with endometrial cancer, who underwent (18)F-FDG PET/CT for preoperative staging work-up, followed by primary(More)
