We previously reported that 3 p53 wild type (wt) MYCN amplified (MNA) neuroblastoma cell lines failed to G1 arrest after DNA damage despite induction of p53, p21(WAF1) and MDM2. We hypothesised that this was due to high MYCN expression. p53 responses to DNA damage were examined in an additional 13 p53 wt neuroblastoma cell lines. MNA was significantly(More)
The mechanism behind the beneficial effects of enteral nutrition (EN) for patients with acute pancreatitis (AP) is largely unknown. Adipokines, as mediators of metabolism and inflammation, may be a possible mechanism. The study aimed to investigate the effect of EN on adipokines early in the course of AP. Patients with AP were randomised to EN or(More)
Adipokines have many homeostatic roles, including modulation of glucose metabolism, but their role in the pathophysiology of hyperglycemia associated with acute and critical illnesses in general, and acute pancreatitis (AP) in particular, is largely unknown. This study aimed to investigate the relationship between a panel of adipokines and hyperglycemia in(More)
BACKGROUND Impaired motor and hormonal gastrointestinal functions have been implicated in the pathogenesis of acute pancreatitis. The aim of the present study was to investigate the predictive value of the Gastroparesis Cardinal Symptom Index and serum ghrelin in the development of clinically meaningful outcomes in patients with acute pancreatitis.

Laparoscopic surgery for adrenal tumors is the gold standard for benign tumors; however, its role for adrenal cancer, metastases, and large suspicious lesions remains controversial. This aspect becomes clinically more important as larger incidentaloma are being detected with increasing frequency. Here, we discuss a rare case of a giant 14-cm adrenal(More)
BACKGROUND With the rising prevalence of obesity, its impact on the severity and outcome of acute pancreatitis remains an important consideration when managing obese patients with acute pancreatitis. OBJECTIVE To determine the clinical relevance of obesity in acute pancreatitis. METHODS A series of clinically relevant questions were framed which formed(More)
AIM To assess the effects of ischemic preconditioning (IPC, 10-min ischemia/10-min reperfusion) on steatotic liver mitochondrial function after normothermic ischemia-reperfusion injury (IRI). METHODS Sixty male Sprague-Dawley rats were fed 8-wk with either control chow or high-fat/high-sucrose diet inducing > 60% mixed steatosis. Three groups (n =(More)
The differential diagnosis of submucosal stomach lesions includes gastrointestinal stromal tumour (GIST), leiomyoma, synovial sarcomas, perineurioma, myxoid chondrosarcoma, myoepithelial tumour and other rare mesenchymal tumours. GISTs are well-defined lesions with distinctive morphologic and histogenetic characteristics that show 95% positive staining for(More)
