PURPOSE The aim of study was to evaluate the usefulness of serum HER2 as a therapeutic response indicator in patients with HER2 positive metastatic breast cancer (MBC). MATERIALS AND METHODS The levels of serum HER2 and CA15.3 were assayed in 148 serial serum samples from 50 HER2 positive MBC patients at both the baseline and follow-ups. The changes in(More)
Citrus fruits have been used as an edible fruit and a traditional medicine since ancient times. In particular, the peels of immature citrus fruits are used widely in traditional herbal medicine in Korea, as they are believed to contain bioactive components exerting anti-inflammatory activity. This study examined whether the crude methanol extract of Citrus(More)
BACKGROUND The Korean Laboratory Accreditation Program (KLAP) by the Korean Society of Laboratory Medicine (KSLM) was started in 1999. We summarized history and achievement of KLAP for the last 8 yr. METHODS We analyzed 8 yr data (1999-2006) of historical events, trends of participating laboratories, and scores according to the impact of the question to(More)
Ginsenosides and withanolides are the secondary metabolites from Panax ginseng and Withania somnifera, respectively. These compounds have similar biological properties. Two-dimensional electrophoresis (2-DE) analysis was utilized to reveal the protein profile in the roots of both plants, with the aim of clarifying similarly- and differentially-expressed(More)
Lonicera japonica THUNB., which abundantly contains polyphenols, has been used as a traditional medicine for thousands of years in East Asian countries because of the anti-inflammation properties. This study aimed to investigate the anti-inflammatory mechanism of polyphenol components isolated from Korea L. japonica T. by nuclear factor-kappaB (NF-κB) and(More)
OBJECTIVES Smoking is a risk factor for coronary artery disease and triggers vascular injury by platelet aggregation and induces atherosclerosis through induction of oxidative stress. Green tea is known to have antioxidant capacity and anti-platelet activity. DESIGN AND METHODS Twenty adult male smokers ingested 600 mL of green tea for 4 weeks. Their(More)
OBJECTIVES Systemic chemotherapy may lead to immune suppression and possible reactivation of hepatitis B virus (HBV), suggesting prophylactic antiviral therapy in cancer patients with HBV. Transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) is not a systemic chemotherapy, but has been partially associated with HBV(More)
BACKGROUND Immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) are reliable ways to identify overexpression or amplification of the HER-2/neu (HER2, symbol ERBB2) gene, but each technique requires a high-quality tissue sample, which may not be available. We investigated whether serum concentrations of the HER2 extracellular domain (ECD)(More)
OBJECTIVES Small dense LDL, low density lipoprotein (LDL) particles with small size and high density, is regarded as a significant risk factor for cardiovascular diseases. Diabetes mellitus is one of the conditions accompanied by increased small dense LDL. We analyzed LDL subclass in type 2 diabetics and normal controls with LipoPrint LDL System to(More)
Functions of neuronal circuit are fundamentally modulated by its quality and quantity of connections. Assessment of synapse, the basic unit for a neuronal connection, is labor-intensive and time-consuming in conventional culture systems, due to the small size and the spatially random distribution. In the present study, we propose a novel 'synapse(More)
