Extraction of high-quality RNA is a crucial step in gene expression profiling. To achieve optimal RNA extraction from frozen blood, the performance of three RNA extraction kits- TRI reagent, PAXgene blood RNA system (PAXgene) and NucleoSpin RNA blood kit (NucleoSpin)- was evaluated. Fifteen blood specimens collected in tubes containing potassium(More)
Granulocytosis occurs in 40% of patients with lung and gastrointestinal cancers, 20% of patients with breast cancer, 30% of patients with brain tumor and ovarian cancer and 10% of patients with renal cell carcinoma. Granulocytosis occurs because of production of G-CSF, GM-CSF and IL-6. Uterine cervical carcinoma with granulocytosis as a paraneoplastic(More)
Secondary hemophagocytic lymphohistiocytosis (HLH) can be associated with various diseases including infections and lymphoma. The clinical findings of HLH can be explained by an increased production of cytokines such as tumor necrosis factor alpha (TNF-alpha). As not all the patients with infection or lymphoma have secondary HLH, we investigated the(More)
This study assessed the association of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection with non-Hodgkin's lymphoma in a highly HBV-endemic area. The prevalence of either HBV or HCV infection in 235 patients with non-Hodgkin's lymphoma was compared with that of an age- and sex-matched hospital control group of 235 patients. The prevalence of(More)
Submicroscopic deletions of genes in recurrent chromosomal rearrangements occur frequently in hematologic malignancies, but their incidences have not been reported clearly. We investigated the incidence of submicroscopic deletions and their association with specific genetic rearrangements in various hematologic malignancies. A fluorescence in situ(More)
Piperlongumine, a natural alkaloid isolated from the long pepper, selectively increases reactive oxygen species production and apoptotic cell death in cancer cells but not in normal cells. However, the molecular mechanism underlying piperlongumine-induced selective killing of cancer cells remains unclear. In the present study, we observed that human breast(More)
Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for many nosocomial and community-acquired infections, resulting in significant morbidity and mortality. A practical way to limit the spread of MRSA is early detection and proper treatment. However, screening culture for MRSA typically requires 2-3 days. The Xpert MRSA assay (Cepheid,(More)
BACKGROUND Insufficiency of the pulmonary surfactant system is the primary cause of respiratory distress syndrome (RDS) in preterm infants. Genetic factors, including specific single-nucleotide polymorphisms in the genetic components of surfactant protein A (SP-A1 and SP-A2), affect protein structure and function, as well as risk of RDS. OBJECTIVE We(More)
PURPOSE Piperlongumine (PL) has been shown to selectively induce apoptotic cell death in cancer cells via reactive oxygen species (ROS) accumulation. In this study, we characterized a molecular mechanism for PL-induced cell death. METHODS Cell viability and cell death were assessed by MTT assay and Annexin V-FITC/PI staining, respectively. ROS generation(More)
