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)
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)
Ewing sarcoma (ES) is an aggressive malignancy driven by an oncogenic fusion protein, EWS-FLI1. Neuropeptide Y (NPY), and two of its receptors, Y1R and Y5R are up-regulated by EWS-FLI1 and abundantly expressed in ES cells. Paradoxically, NPY acting via Y1R and Y5R stimulates ES cell death. Here, we demonstrate that these growth-inhibitory actions of NPY are(More)
INTRODUCTION Laparoscopic adjustable gastric banding is the most frequently performed bariatric procedure for the treatment of morbid obesity and is associated with low morbidity and mortality. Complications related to obesity surgery are rare and their presentation is often non-specific. Thus, it is highly important for physicians who are practising(More)
Nasogastric (NG) intubation is one of the most commonly performed clinical procedures. Real-time localization and tracking of the NG tube passage at the larynx region into the esophagus is crucial for safety, but is lacking in current practice. In this paper, we present the design, analysis and evaluation of a non-invasive real-time localization system(More)
The rapid reversal of diabetes, hypertension, hyperlipidaemia and obesity by surgical means has challenged accepted doctrines regarding the management of metabolic syndrome. Sleeve gastrectomy, which developed initially as a preparatory procedure for biliopancreatic diversion with duodenal switch, has seen an exponential rise in popularity as an effective(More)
Recently, we reported that human leukocyte antigen (HLA) class I expression is predominantly regulated by the mitogen-activated protein kinase (MAPK) pathway as one of the oncogenic regulations of HLA class I expression. In the present study, we examined mechanisms of how HLA class I and PD-L1 are regulated by MAPK inhibitors and interferon-γ (IFN-γ).(More)
Gastric carcinoma rarely presents as a perforation, but when it does, is perceived as advanced disease. The majority of such perforations are Stage III/IV disease. A T1 gastric carcinoma has never been reported to perforate spontaneously in English literature. We present a 56 year-old Chinese male who presented with a perforated gastric ulcer.(More)
INTRODUCTION. Tumour cell implantation is a rare complication in patients with head and neck cancers, who have undergone percutaneous endoscopic gastrostomy (PEG) tube placement. It has not been reported in patients who underwent a PEG insertion via the radiological or introducer technique. We describe a novel case presentation of metastatic disease in a(More)
