OBJECTIVES Bishphenol A (BPA) is a representative endocrine disruptor and is also known as a xenoestrogen. The objective of the present study is to investigate how many patients are exposed to BPA and to analyze the relationships between serum BPA concentration, bone mineral density (BMD) and biochemical bone markers in postmenopausal women with(More)

It is unclear whether the quality of bowel preparation affects colonoscopic detection of non-polypoid colorectal neoplasms (NP-CRNs). To evaluate the impact of bowel-cleansing quality on detection of NP-CRNs. We performed a retrospective analysis of asymptomatic screening colonoscopy cases after standardized bowel preparation at an academic teaching(More)
We present an instance of successful use of an intubating laryngeal mask airway (LMA-Fastrach) and a Cook airway exchanger (CAE) for ventilation and intubation in a patient with severe ankylosing spondilitis (AS) receiving total hip arthroplasty. This measure may serve as an effective alternative for airway management in patients with difficult airway. A(More)
AIMS Inflammatory processes are involved in bone remodeling. C-reactive protein (CRP) is an acute phase reactant that reflects different degrees of inflammation. Accumulating evidence suggests that CRP is an inflammatory marker and a direct cause of disease. Therefore, we examined the direct effects of CRP on bone cells. MAIN METHODS We used RAW 264.7(More)
Mannose-binding lectin (MBL) acts in the innate immune response to Helicobacter pylori. Interleukin 8 (IL-8) is a potent cytokine produced by gastric epithelial cells in response to H. pylori. We aimed to investigate whether polymorphisms in MBL2 and IL-8 influence susceptibility to H. pylori infection, and the associations of these polymorphisms with the(More)
Approximately 3-15% of patients who have undergone removal of bile duct stones with endoscopic sphincterotomy have recurrence of stones which often presents as acute cholangitis. Despite better understanding on the factors and mechanisms underlying the recurrence of bile duct stones achieved during the past few decades, endoscopic removal still remains the(More)
A 53-year-old woman was admitted with epigastric discomfort and weakness. Laboratory examination at admission showed mild anemia and proteinuria. Esophagogastroduodenoscopy revealed marked mucosal atrophy, diffuse nodularity and granular appearance with mucosal friability. Biopsy was performed on the antrum and body of the stomach. On the next day, the(More)
During treatment for peptic ulcer bleeding (PUB), it is imperative to determine the effect of antiplatelet agents on recurrent bleeding in order to balance risks and benefits. We compared the rate of recurrent bleeding in antiplatelet users and non-users. This retrospective study analyzed prospectively collected data from PUB patients treated by endoscopic(More)
BACKGROUND/AIMS Lactose-free milk (LFM) is available for nutrient supply for those with lactose intolerance (LI). However, there are no consistent results of the efficacy of LFM in LI subjects. We aimed to examine the changes of gastrointestinal (GI) symptoms and hydrogen breath test (HBT) values after ingestion of lactose contained milk (LCM) vs. LFM. (More)
