PURPOSE To prospectively evaluate the accuracy of multi-detector row computed tomography (CT) gastrography for preoperative staging of gastric cancer, with pathologic and surgical results as the reference standard. MATERIALS AND METHODS This study was approved by the institutional review board, and patients gave written informed consent. One hundred six(More)
BACKGROUND & AIMS Despite increasing use of various imaging examinations for non-invasive assessment of hepatic steatosis (HS), their relative accuracy is unknown. The objective of this study is to prospectively compare the accuracy of computed tomography (CT), dual gradient echo magnetic resonance imaging (DGE-MRI), proton magnetic resonance spectroscopy(More)
Hepatocellular carcinoma (HCC) is the third most frequent cause of cancer death in South Korea, but genetic susceptibility factors of HCC have not been examined extensively. Methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) play an essential role in both DNA synthesis and methylation and polymorphisms in the MTHFR gene,(More)
A robotic system (da Vinci® Surgical System, Intuitive Surgical Inc., Sunnyvale, CA, USA) has technical advantages over conventional laparoscopic surgery because it increases the precision and accuracy of anatomical dissection. The present study aimed to compare the short-term outcomes between robot-assisted intersphincteric resection (ISR) and laparoscopic(More)
BACKGROUND Little data are available about the learning curve for robotic rectal resection. OBJECTIVE The purpose of this work was to provide a multidimensional analysis of the learning process in patients undergoing robotic total mesorectal excision for rectal cancer. DESIGN This was a retrospective review of a prospectively collected database designed(More)
PURPOSE The goal of this study is to evaluate the technical feasibility, safety, and clinical outcomes of totally laparoscopic colectomy with transvaginal anastomosis and extraction of specimen in female patients with right-sided colon cancer. METHODS A review of prospectively collected database at the Kyungpook National University Hospital from April(More)
Our recent work demonstrated that chitin treatment modulated the expression of 118 transcription factor (TF) genes in Arabidopsis. To investigate the potential roles of these TF in chitin signaling and plant defense, we initiated an interaction study among these TF proteins, as well as two chitin-activated mitogen-activated protein kinases (MPK3 and MPK6),(More)
PURPOSE To prospectively compare diagnostic performance of diffusion-weighted (DW) imaging, gadoxetic acid-enhanced magnetic resonance (MR) imaging, both techniques combined (combined MR imaging), and computed tomography (CT) for detecting colorectal hepatic metastases and evaluate incremental value of MR for patients with potentially curable colorectal(More)
Several mammals--including sheep, mice, cows, goats, pigs, rabbits, cats, a mule, a horse and a litter of three rats--have been cloned by transfer of a nucleus from a somatic cell into an egg cell (oocyte) that has had its nucleus removed. This technology has not so far been successful in dogs because of the difficulty of maturing canine oocytes in vitro.(More)
Although the vagina is considered a viable route during laparoscopic surgery, a number of concerns have led to a need to demonstrate the safety of a transvaginal approach in colorectal surgery. However, the data for transvaginal access in left-sided colorectal cancer are extremely limited, and no study has compared the clinical outcomes with a conventional(More)
