Mapping of tissue structure at the cellular, circuit, and organ-wide scale is important for understanding physiological and biological functions. A bio-electrochemical technique known as CLARITY used for three-dimensional anatomical and phenotypical mapping within transparent intact tissues has been recently developed. This method provided a major advance(More)
MicroRNAs (miRNAs) regulate gene expression through degradation and/or translational repression of target mRNAs. Dysregulations in the miRNA machinery may be involved in carcinogenesis of colorectal cancer (CRC). The purpose of the current study was to evaluate the DiGeorge syndrome critical region gene 8 (DGCR8) and argonaute 2 (AGO2) mRNA expression in(More)
BACKGROUND/AIMS Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are predominantly known as medication-induced diseases. However, at our institution, we have experienced more cases of non-drug-related SJS and TEN than expected. Therefore, we studied the difference between non-drug-related and drug-related SJS and TEN in terms of clinical(More)
Recent changes in healthcare systems have changed the epidemiologic paradigms in many infectious fields including bloodstream infection (BSI). We compared clinical characteristics of community-acquired (CA), hospital-acquired (HA), and healthcare-associated (HCA) BSI. We performed a prospective nationwide multicenter surveillance study from 9 university(More)
BACKGROUND/AIMS Although the incidence of T-cell non-Hodgkin's lymphoma (NHL) is higher in Far East Asia than in Western countries, its incidence and clinical course in Korea are not well-defined. Therefore, we assessed the relative frequency and clinical features of T-cell NHL in Korea. METHODS We performed a retrospetcive analysis of 586 patients with(More)
BACKGROUND Primary central nervous system lymphoma (PCNSL) rarely relapses in extracranial sites, and no specialized guidelines for follow-up evaluation have been proposed. METHODS We analyzed 65 patients with newly diagnosed PNCSL to evaluate the pattern of relapse and prognostic factors. RESULTS Of the 65 patients analyzed, 55 had only parenchymal(More)
BACKGROUND/AIMS As bacterial resistance to antimicrobial agents has grown due to the increasing use of antimicrobial agents, we sought to evaluate the suitability of ceftriaxone usage (representative of third generation cephalosporins) at 10 university hospitals in Korea. METHODS We prospectively evaluated the appropriateness of antibiotic usage in 400(More)
Fibroma of the tendon sheath is an uncommon soft tissue tumor presenting as a solitary, slow-growing, firm, painless, small nodule, which shows strong attachment to the tendon or tendon sheath. It is usually localized on fingers and hand tendons in adults between the age of 20 and 40 years old. This case concerns a 61-year-old man presenting with a 5-year(More)
Altered expression of microRNA (miRNA) machinery components may play an important role in breast cancer progression. The objective of the current study was to evaluate Drosha, the DiGeorge syndrome critical region gene 8 (DGCR8), Dicer, and Argonaute 2 (AGO2) mRNA expression in invasive breast carcinoma (IBC) and to assess the value of clinical parameters(More)
