PURPOSE DNA BER pathway is related with carcinogenesis. We hypothesized that functional polymorphisms of three BER genes, XRCC1, apurinic/apyrimidinic endonuclease (APE1), and ADPRT, confer risks for DTC and its progression. EXPERIMENTAL DESIGN Five common nonsynonymous single nucleotide polymorphisms (Arg194Trp, Arg280His, and Arg399Gln for XRCC1;(More)
Studies have shown an association between diabetes and cancer in Western countries; but this, as well as the influence of associated metabolic factors, must be confirmed by a prospective study in other population groups. This study aimed to investigate whether the strong association of cancer and diabetes is independent from the influence of hypertension,(More)
Vascular endothelial growth factor (VEGF) is a potent stimulator for angiogenesis. It has been implicated in growth and metastasis of thyroid cancer. Three functional single nucleotide polymorphisms (SNPs) of VEGF (-2578C/A, -634G/C, and +936C/T) are known to be related with VEGF expression. We conducted a case-control study to evaluate the genetic effects(More)
BACKGROUND AND AIM It is known that ultrasonography (US) cannot differentiate between non-alcoholic fatty liver disease (NAFLD) and steatohepatitis. However, US can accurately estimate the severity of the steatosis. The clinical significance of severe hepatic fatty change by US has not been explored. The aim of this study was to investigate the relationship(More)
OBJECTIVES There is growing evidence with regard to the association between hepatitis C virus (HCV) infection and type 2 diabetes mellitus (T2DM). However, the mutual link and related virological implication have not been fully clarified. The impact of hepatitis B virus (HBV) infection on the epidemiological link remains unclear. This study aimed to(More)
Pioglitazone was reported to improve hepatic steatosis and necroinflammation in human studies. To investigate whether the hepato-protective effect of pioglitazone was associated with an improvement of antioxidant defense mechanism, oxidative DNA damage and repair activity were determined in a high fat diet model. Male C57BL/6 mice were respectively fed with(More)
PURPOSE The nonrecurrent laryngeal nerve (NRLN) is a rare anatomical variant but associated with high risk of nerve injury during thyroid and parathyroid operations. Therefore, intraoperative detection and verification of NRLN are necessary. METHOD A total of 390 consecutive patients who underwent thyroid and parathyroid operations (310 RLNs dissected on(More)
The increase of apo-/holo-retinol-binding protein 4 (RBP4) concentrations has been found in subjects with renal dysfunction and even in diabetic patients with microalbuminuria. Holo-RBP4 is recognized to possess cytoprotective function. Therefore, we supposed that the relative increase in apo-RBP4 might induce cell damage. In this study, we investigated the(More)
PURPOSE Extensive dissection of recurrent laryngeal nerve (RLN) is inevitable in some complicated thyroid operations. The study aimed to determine whether extensive dissection of RLN increases the risk of nerve injury. METHOD Three hundred thirty-one patients (506 nerves at risk) who underwent thyroid operations with intraoperative neuromonitoring were(More)
Angiotensin II (Ang II), the physiologically-active product of the renin-angiotensin system (RAS), has recently been found to be an adipokine secreted by adipocytes. Although Ang II is known to exert its effects via angiotensin II receptor type 1 (AT1R) or type 2 (AT2R), the roles of the two receptors in the adipose tissue are unclear. Apelin, another(More)
