Recent work led to recognize sessile serrated adenomas (SSA) as precursor to many of the sporadic colorectal cancers with microsatellite instability (MSI). However, comprehensive analyses of DNA methylation in SSA and MSI cancer have not been conducted. With an array-based methylation sensitive amplified fragment length polymorphism (MS-AFLP) method we(More)
Patients with long-standing ulcerative colitis (UC) have higher risk of developing colorectal cancer. Albeit the causes remain to be understood, epigenetic alterations have been suggested to play a role in the long-term cancer risk of these patients. In this work, we developed a novel microarray platform based on methylation-sensitive amplified fragment(More)
Polyamines (spermine and spermidine) play many important roles in cellular function and are supplied from the intestinal lumen. We have shown that continuous high polyamine intake inhibits age-associated pathologies in mice. The mechanism by which polyamines elicit these effects was examined. Twenty-four week old Jc1:ICR male mice were fed one of three(More)
INTRODUCTION Few reports detail adequate surgical management of giant pelvic tumors that traverse the sciatic foramen. PRESENTATION OF CASE We present a case of a giant retroperitoneal pelvic lipoma that presented with a dumbbell shape on imaging, occupying the entire lesser pelvis and protruding to the gluteus through the sciatic foramen. Surgery was(More)
Wandering spleen is a rare clinical entity, and its chronic torsion of the vascular pedicle result in splenic vein occlusion leading to gastric varices. Here, we present a case of wandering spleen complicating gastric varices in a 40-year-old female. Three-dimensional CT (3D-CT) clearly showed the disruption of the splenic vein at the origin of the vascular(More)
We previously reported that the Pleckstrin and Sec7 domain-containing (PSD) gene is preferentially methylated in patients with ulcerative colitis (UC) who developed colorectal cancer (CRC), and is implicated in UC-associated carcinogenesis through its inhibition of apoptosis. This study aimed to determine the potential(More)
A charge-mosaic membrane was prepared from a pentablock copolymer of the BABCB type by selectively introducing anion and cation exchange groups into the microseparated phases. The three-layer lamellar structure of the starting pentablock copolymer film was not disturbed by the modifications. The membrane obtained was highly permeable only to sodium chloride(More)
