BACKGROUND Some strains of plant growth-promoting rhizobacteria (PGPR) elicit induced systemic resistance (ISR) by emission of volatile organic compounds (VOCs) including short chain alcohols, acetoin, and 2,3-butanediol. The objective of this study was to evaluate whether species-specific VOCs from PGPR strain Paenibacillus polymyxa E681 can promote growth(More)
Atmospheric pollution increases cardiopulmonary morbidity and mortality by unexplained mechanisms. Phagocytosis of fine particles (PM(10)) by rabbit alveolar macrophages elevates white blood cells (WBC) by releasing precursors from the bone marrow and this could contribute to the pathogenesis of cardiopulmonary disease. The present study examined the(More)
An innovative polymer lab-on-a-chip (LOC) for reverse transcription (RT)-polymerase chain reaction (PCR) has been designed, fabricated, and characterized for point-of-care testing (POCT) clinical diagnostics. In addition, a portable analyzer that consists of a non-contact infrared (IR) based temperature control system for RT-PCR process and an optical(More)
A novel siRNA delivery system based on polyelectrolyte complex (PEC) micelles was introduced in this study. Vascular endothelial growth factor (VEGF) siRNA was conjugated to poly(ethylene glycol) (PEG) via a disulfide linkage (siRNA-PEG). The siRNA-PEG conjugate could form PEC micelles by interacting with cationic polyethylenimine (PEI) as a core forming(More)
Peroxisome proliferator-activated receptor γ (PPARγ) regulates multiple signaling pathways, and its agonists induce apoptosis in various cancer cells. However, their role in cell death is unclear. In this study, the relationship between ciglitazone (CGZ) and PPARγ in CGZ-induced cell death was examined. At concentrations of greater than 30 μM, CGZ, a(More)
Pre-engraftment syndrome (PES) is poorly characterized, and its clinical significance and the prognostic impact after unrelated cord blood transplantation (CBT) are unclear. To address these issues, we retrospectively analyzed the incidence, risk factors, and clinical outcomes of PES in unrelated CBT recipients. Data of 381 patients who received unrelated(More)
Although AKT ⁄ protein kinase B is constitutively active in nonsmall cell lung cancer (NSCLC) cells and is an attractive target for enhancing the cytotoxicity of therapeutic agents, the distinct roles of the AKT isoforms in NSCLC are largely unknown. In the present study, we investigated the roles of AKT1 and AKT2 in NSCLC cells using RNAi. The siRNA(More)
PURPOSE The aim of this study is to define distinctive clinicopathologic features of malignant lymphoma in pediatric and young adult patients, particularly in Korea. PATIENTS AND METHODS From May 1993 to November 2005, 294 pediatric and young adult patients (age range, 0-31 years) with malignant lymphoma were analyzed in this study at Samsung Medical(More)
Patients with hematologic malignancies who relapse after their first hematopoietic stem cell transplantation tend to have poor prognoses. One option for these patients is a second allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, there are few reports of second allo-HSCT therapy in children with relapsed hematologic malignancies.(More)
Through this study, we aimed to validate several biomarkers that have been known to possibly predict the outcomes of the trastuzumab and paclitaxel (TP). Human epidermal growth factor 2 (HER2) positive metastatic breast cancer (MBC) patients who had been treated with TP in single institute from 2006 to 2009 were included in this study. For procured formalin(More)
