PURPOSE To identify the expression of gonadotropin-releasing hormone (GnRH) messenger ribonuclueic acid (mRNA) and localize GnRH receptors in mature rat and adult human testes. MATERIALS AND METHODS In situ hybridization and enzymatic receptor binding localization were performed. RESULTS GnRH mRNA was expressed within the seminiferous tubules in both(More)
BACKGROUND The recent ADEMEX study (Paniagua R, Amato D, Vonesh E et al. J Am Soc Nephrol 2002; 13: 1307-1320) indicates that peritoneal small solute clearance is not as critical for the survival of peritoneal dialysis (PD) patients as thought previously. On the other hand, low residual renal function (RRF), inflammation and an increased peritoneal(More)
PURPOSE The purpose of this study was to evaluate deep neck space infection (DNSI) with particular attention to the differences in the spaces involved and in complications between odontogenic and nonodontogenic groups with CT. METHOD Forty-four patients (21 odontogenic and 23 nonodontogenic) were included in this study. Among odontogenic DNSI cases, 15(More)
The Rab class of low molecular weight GTPases has been implicated in the regulation of vesicular trafficking between membrane compartments in eukaryotic cells. The Rab3 family consisting of four highly homologous isoforms is associated with secretory granules and synaptic vesicles. Many different types of experiments indicate that Rab3a is a negative(More)
OBJECTIVES To evaluate the influence of initial nutritional status on continuous ambulatory peritoneal dialysis (CAPD) patient survival and to identify factors determining initial nutritional status and patient mortality. DESIGN Prospective single-center study. SETTING Kidney Center, Soon Chun Hyang University Hospital. PATIENTS A total of 91(More)
Progressive peritoneal fibrosis, membrane hyperpermeability, and ultrafiltration failure have been observed in patients on long-term peritoneal dialysis (PD). The present study tested the hypothesis that reactive oxygen species (ROS) generated by conventional PD solution (PDS) mediate functional and structural alterations of peritoneal membrane in vivo.(More)
The presence of an extra copy of human chromosome 21 (trisomy 21), especially region 21q22.2, causes many phenotypes in Down syndrome, including mental retardation. To study genes potentially responsible for some of these phenotypes, we cloned a human candidate gene (DYRK) from 21q22.2 and its murine counterpart (Dyrk) that are homologous to the Drosophila(More)
OBJECTIVE The study aimed to investigate expression of p53, p27 and Jun activation domain-binding protein 1 (Jab1) proteins in epithelial ovarian tumors and the values of these factors as discriminating markers for the transformation of borderline tumors to cancers. METHODS Forty-seven cases of paraffin-embedded tissues of epithelial ovarian tumors(More)
BACKGROUND Many patients with end-stage renal disease (ESRD) are malnourished and cross-sectional studies show that markers of malnutrition may predict death. Serum albumin (S-albumin), the commonest nutritional marker, has been criticized because it is so closely related to the effects of inflammation and other non-nutritional factors. Consequently, we(More)
