There is an increased prevalence of imprinting disorders, such as Beckwith-Wiedemann syndrome, associated with human assisted reproductive technologies (ART). Work on animal models suggests that in vitro culture may be the source of these imprinting errors. However, in this study we report that, in some cases, the errors are inherited from the father. We(More)
BACKGROUND & AIMS Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is indispensable for the diagnosis of solid pancreatic lesions (SPLs). However, initial attempt of EUS-FNA can be inconclusive. We retrospectively evaluated the ability of repeat EUS-FNA at a tertiary referral hospital to obtain a conclusive cytological diagnosis after the(More)
BACKGROUND Clinical studies have demonstrated that oxaliplatin, a novel platinum derivative, is a potent chemotherapeutic agent, especially when combined with other reagents. The aim of the present study was to explore the mechanism of such action. METHODS Using colon cancer cell lines, we examined changes in cell cycle, apoptosis and mitotic catastrophe(More)
BACKGROUND AND AIM Published studies have revealed the diagnostic yield of cytology obtained from endoscopic retrograde cholangiopancreatography (ERCP) in distinguishing malignant and benign intraductal papillary mucinous neoplasm (IPMN). However as a result of small sample sizes, the overall magnitude of benefit is unknown. Additionally, the optimal(More)
AIM Percutaneous Endoscopic Gastrostomy (PEG) placement is a useful but invasive method. Recently, the hemodynamic change of ultrathin transnasal esophagogastroduodenoscopy (transnasal EGD) was reported as less than that of conventional transoral EGD (transoral EGD). This study compared hemodynamic changes between transnasal EGD and transoral EGD in the(More)
The aim of this study was to review the efficacy of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) in diagnosing gallbladder (GB)-protruded lesions. Thirty-eight patients underwent CH-EUS for the diagnosis of GB-protruded lesions. Twenty-four patients whose major axes of their largest lesions were longer than 10 mm were recruited. The(More)
OBJECTIVES Differential diagnosis of malignant and benign intraductal papillary mucinous neoplasms (IPMNs) is essential to determine the optimal treatment. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is currently used to diagnose pancreatic cystic lesions worldwide, but few studies have focused on the diagnostic yield to distinguish(More)
INTRODUCTION A prior study with 22-gauge needles recommended more than seven needle passes for endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) of solid pancreatic lesions (SPL) without onsite cytopathology for optimal acquisition of cytopathological diagnosis. The feasibility of this recommendation should be re-evaluated considering the(More)
BACKGROUND/PURPOSE To analyze the value of ultrasound scan (US) in the preoperative identification of a contralateral patent processus vaginalis (CPPV), the authors investigated the presence of CPPV by US in children with clinically diagnosed unilateral inguinal hernias. METHODS Three hundred forty-eight patients (168 boys and 180 girls) with unilateral(More)
BACKGROUND Although 5-fluorouracil (5-FU)-based combination chemotherapy (i.e. FOLFIRINOX) has demonstrated effectiveness against pancreatic cancer, novel therapeutic strategies must be developed to increase the therapeutic window of these cytotoxic agents. Genistein is a soy-derived isoflavone with pleiotropic biological effects that can enhance the(More)
