Gold nanoparticles (AuNPs) have been extensively investigated as an emerging delivery carrier of various biopharmaceuticals. Instead of nonspecific polyethylene glycol (PEG) conjugated interferon α (IFNα) for the clinical treatment of hepatitis C virus (HCV) infection, in this work, a target-specific long-acting delivery system of IFNα was successfully developed using the hybrid materials of AuNP and hyaluronic acid (HA). The HA-AuNP/IFNα complex was prepared by chemical binding of thiolated HA

Mycoplasma hominis (M. hominis) and Ureaplasma urealyticum (U. urealyticum) are important opportunistic pathogens that cause urogenital infections and complicate pregnancy. The aim of this study was to investigate the prevalence, effects on pregnancy outcomes, and antimicrobial susceptibilities of M. hominis and U. urealyticum. We tested vaginal swabs obtained from 1035 pregnant women for the presence of genital mycoplasmas between June 2009 and May 2014. The laboratory and clinical aspects of g

Introduction. Mean platelet volume (MPV) has been thought as a useful index of platelet activation. It is supposed that MPV is also associated with several inflammatory and infectious diseases. Korea still has a high incidence of tuberculosis (TB). The aim of this study was to investigate MPV as an inflammatory marker in TB patients. Materials and Methods. MPV were determined in 221 patients with TB and 143 individuals for control group. MPV was estimated by an Advia 2120 (Siemens Healthcare Dia

Actinic keratosis (AK) and Bowen's disease (BD) are common patterns of in situ squamous cell carcinoma of the epidermis. In AK, atypical keratinocytes proliferate in the lower portion of the epidermis including the basal layer. In contrast, BD features atypical squamous cells in all portions of the epidermis but initially leaves basal cells in palisades along the basement membrane. To characterize immunohistochemically keratocyte proliferation in AK and Palisading Basal Cells (PBC) in BD, we sta

Diagnostic reference level (DRL) is employed to optimize the radiation doses of patients. The objective of this study is to review the DRLs for interventional procedures in Korea and abroad. Literature review was performed to investigate radiation dose index and measurement methodology commonly used in DRL determination. Dose area product (DAP) and fluoroscopy time within each major procedure category were systematically abstracted and analyzed. A wide variation was found in the radiation dose.

This case report suggests that a combination of FNAC and culture is a simple and useful method of diagnosing fungal infections. Early diagnosis by FNAC makes possible the early initiation of treatment.

Our results indicated that the incidence of PAPE was very low (0.023%) and occurred mainly in the postpartum period after cesarean section. However, its maternal mortality rate was significantly high (7.7%). Therefore, we suggest that immediate diagnosis and prompt treatment should be prioritized for improvement of PAPE patients' survival rate.

An appendiceal foreign body is very rare in infant and there are currently no treatment guidelines. We report 2 cases of appendiceal foreign body including infant who gave us difficult decisions.

Neointimal hyperplasia of vascular smooth muscle cells (VSMC) plays a critical role in atherosclerotic plaque formation and in-stent restenosis, but the underlying mechanisms are still incompletely understood. We performed a proteomics study to identify novel signaling molecules organizing the VSMC hyperplasia. The differential proteomics analysis in a balloon-induced injury model of rat carotid artery revealed that the expressions of 44 proteins are changed within 3 days post injury. The combin
