Adipose-derived stem/stromal cells (ASCs) from the anatomically distinct subcutaneous and visceral depots of white adipose tissue (WAT) differ in their inherent properties. However, little is known about the molecular identity and definitive markers of ASCs from these depots. In this study, ASCs from subcutaneous fat (SC-ASCs) and visceral fat (VS-ASCs) of(More)
BACKGROUND An incisional hernia develops in 3% to 13% of laparotomy incisions, with primary suture repair of ventral hernias yielding unsatisfactory results. The introduction of a prosthetic mesh to ensure abdominal wall strength without tension has decreased the recurrence rate, but open repair requires significant soft tissue dissection in tissues that(More)
Obesity is a major public health concern around the world, including Asia. Bariatric surgery has grown in popularity to combat this rising trend. An e-mail questionnaire survey was sent to all the representative Asia-Pacific Metabolic and Bariatric Surgery Society (APMBSS) members of 12 leading Asian countries to provide bariatric surgery data for the last(More)
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) can dramatically ameliorate type 2 diabetes mellitus (T2DM) in morbidly obese patients. However, there is little evidence supporting the effectiveness of LRYGB in low body mass index (BMI) patients. The study was designed to evaluate the safety and results of LRYGB for achieving T2DM remission in(More)
The surface marker CD44 has been identified as one of several markers associated with cancer stem cells (CSC) in solid tumors, but its ubiquitous expression in many cell types, including hematopoietic cells, has hindered its use in targeting CSCs. In this study, 28 paired primary tumor and adjacent nontumor gastric tissue samples were analyzed for cell(More)
To develop more effective therapies for patients with advanced gastric cancer, we examined the potential of ex vivo expanded natural killer (NK) cells. We assessed the expression of ligands for NK Group 2 Member D (NKG2D, an important NK activation molecule) in primary tumors from 102 patients with gastric cancer by immunohistochemistry and determined their(More)
BACKGROUND & AIMS It is not clear how the duration of upper endoscopy affects the detection of cancer or premalignant lesions that increase the risk for gastric cancer. We investigated whether the length of time spent performing esophagogastroduodenoscopy (EGD) affects the detection of important pathologic features of the stomach. METHODS We collected(More)
Natural orifice transluminal endoscopic surgery (NOTES) has gained widespread interest as a potentially alternative to laparoscopic surgery, but concerns over peritoneal contaminations are unsolved. The aim of our study was to assess the safety of transluminal surgery by investigating the intraperitoneal bacterial load and contamination during transgastric(More)
BACKGROUND Tumors arising from the esophagogastric junction (OGJ) are increasing in incidence in the west, but data from Asian populations are conflicting. Singapore has a mixed-Asian population with an international lifestyle. This study was designed to examine the changing trends in incidence of gastric cardia cancer (type III) within this population and(More)
