Circulating microRNAs (miRNAs) have emerged as candidate biomarkers of various diseases and conditions including malignancy and pregnancy. This approach requires sensitive and accurate quantitation of miRNA concentrations in body fluids. Herein we report that enzyme-based miRNA quantitation, which is currently the mainstream approach for identifying(More)
Point-based shape representation has received increased attention in recent years, mainly due to its simplicity. One of the most fundamental operations for point set processing is to find the neighbors of each point. Mesh structures and neighborhood graphs are commonly used for this purpose. However, though meshes are very popular in the field of computer(More)
PROBLEM thyroid autoimmunity (TAI), which is T helper (Th)1-cell-mediated autoimmunity to thyrocytes, is associated with increased risk of miscarriages and highly prevalent in women with infertility. We aim at investigating the prevalence of TAI in women with recurrent spontaneous abortions (RSA) or unexplained infertility (UI) and its relationship with(More)
OBJECTIVE The aim of this study was to evaluate the surgical impact of benign ovarian mass on ovarian reserve as measured by serum follicle stimulating hormone (FSH), estradiol (E2) and anti-Müllerian hormone (AMH) levels, antral follicle count (AFC) and ovarian volumes. In addition, the differences in ovarian reserve impairment between endometrioma(More)
Triangular mesh is one of the most popular shape representations in computer graphics and the CAD/CAM/ CAE area. In this paper we present a memory and time efficient topology construction algorithm from triangle soup, which is a set of triangles without connectivity information. The proposed algorithm consists of the following steps: (1) vertex merging, (2)(More)
OBJECTIVE The goal of this study was to evaluate the etiologies and clinical outcomes of Korean recurrent pregnancy loss (RPL) patients. And also, we investigated the differences between primary and secondary RPL patients, between two and three or more pregnancy losses. METHODS One hundred seventy eight women diagnosed as RPL were enrolled. We performed(More)
A patient with a documented history of 2 asystolic episodes associated with venipuncture demonstrates the profound cardioinhibitory effects that vasovagal reactions to blood and injury ("blood-injury phobia") can produce. In approaching a patient with blood-injury phobia, the clinician should place the patient in the Trendelenburg position, apply a cardiac(More)
PROBLEM Women with a history of recurrent pregnancy losses (RPL) and unexplained infertility (UI) have a high incidence of preeclampsia (PE) and other obstetrical complications. We aimed to investigate the incidence of PE and other obstetrical complications in women with RPL or UI who were treated with anti-inflammatory and anticoagulant treatment. (More)
OBJECTIVE This study was aimed to investigate endometrial histology and to find predictable clinical factors for endometrial disease (hyperplasia or cancer) in women with polycystic ovary syndrome (PCOS). METHODS We investigated the endometrial histology and analyzed the relationship between endometrial histology and clinical parameters, such as LH, FSH,(More)
BACKGROUND/AIMS The relationship between colorectal neoplasia and cervical cancer has not been evaluated. This study aimed to assess the prevalence of colorectal adenoma in patients with cervical cancer and compare it with that of control subjects. METHODOLOGY Between January 2005 and December 2009, the medical records of patients diagnosed with cervical(More)
