Published: September 2001

Background: Electrogastrography (EGG) is the non-invasive measurement of gastric electrical activity. With the development of modern technology, improved recording and automated analysis, it is a reliable and accurate technique for the measurement of gastric myoelectrical activity providing information about the frequency and regularity of the gastric slow wave.

Aim: The aim of this report is to evaluate its role in clinical practice.

Methods: The literature is reviewed and its role investigated.

Results: EGG has been successfully used in the investigation of gastroparesis, non-ulcer dyspepsia (NUD), gastric emptying (GE) disorders and diabetes mellitus (DM). EGG also provides an insight into the effect of medications on gastric function, e.g. edrophonium, cisapride, erythromycin and proton-pump inhibitors (PPI).

Conclusions: EGG has a developing role in the assessment of gastric dysfunction and on the effect of medical treatment. The effect of surgery and anaesthesia on gastric myoelectric activity is less clear.

: Gastric cancer (GC) is the leading cause of cancer-related deaths worldwide. C118P, a microtubule inhibitor with anti-angiogenic and vascular-disrupting activities, was proven to be cytotoxic to various cancer cell lines. This study aimed to explore the anti-tumor effect of C118P against gastric cancer and identify its potential target.

Dysregulated inflammation and oxidative stress are strongly implicated in the pathogenesis of inflammatory bowel disease. We have developed a novel therapeutic that targets inflammation and oxidative stress. It is comprised of microRNA-146a (miR146a)-loaded cerium oxide nanoparticles (CNPs) (CNP-miR146a).

(), one of the most prevalent pathogenic bacteria worldwide, is the leading cause of gastritis, gastric intestinal metaplasia, and gastric cancer. Antibiotics, the conventional treatment for eliminating , often lead to severe bacterial resistance, gut dysbiosis, and hepatic insufficiency and fail to address the inflammatory response or gastric mucosal damage caused by infection. In this study, based on 10-week animal experiments, two models of NCUH062003 for the prophylaxis and therapy of infection in C57BL/6 mice were established; a comprehensive comparative analysis was performed to investigate the anti- effect of probiotics, the reduction in inflammation, and repair of gastric mucosal damage.

Background: Bariatric surgery is a safe and effective procedure for treating obesity and metabolic conditions such as type 2 (T2DM). Remodeling of the extracellular matrix (ECM) supports adipose tissue expansion and its metabolic activity, where matrix metalloproteinases (MMPs) play a key role in ECM regulation. The MMPs, particularly MMP-2 and MMP-9, are elevated in patients with morbid obesity, metabolic syndrome, and T2DM.

Background: There is an upward shift in the incidence and localization of gastric cancer (GC). Proximal gastrectomy (PG) has been advocated as an alternative operation for upper-third GC. An uneventful postoperative course is currently measured using a well-defined textbook outcome (TO), which represents a composite of surgical quality metrics.
