Unlabelled: Many recent studies showed that EGG signal can be used to diagnose and monitor patients with gastric motility disorders.
Material And Method: This paper presents the way to record and process the EGG signal, and the results of study on a sample of 10 patients. These patients are initially evaluated by upper endoscopy were are normal without gastric motility dysfunction or some gastric lesions. The EGG signals are obtained with the surface electrodes placed along the projection of the stomach axis on the abdomen, amplified with an electrogastrogram amplifier module and analyzed on a personal computer. The used signal analysis method is based on spectral analysis of EGG signals.
Results: This method showed a normal gastric activity for seven patients of the sample and a gastric dysryhthmia for three of them.
Conclusion: The computerized spectral analysis of electrogastrography signals proves to be a non-invasive, high sensitive, reproducible and cost-effective method for the diagnosis of gastric dysrhythmias and normal gastric electrical rhythm even in sub clinical patients.

Background: Triple-negative breast cancer (TNBC) is highly invasive and metastatic to the lymph nodes. Therefore, it is an urgent priority to distinguish novel biomarkers and molecular mechanisms of lymph node metastasis as the first step to the disease investigation. Long non-coding RNAs (lncRNAs) have widely been explored in cancer tumorigenesis, progression, and invasion.

Introduction: Proton pump inhibitors (PPIs) and potassium-competitive acid blockers (P-CABs) are widely used to manage gastric acid-related disorders by inhibiting hydrochloric acid (HCl) secretion from parietal cells in the stomach. Although PPIs are known to have anti-inflammatory properties beyond their role in inhibiting gastric acid secretion, research on P-CABs is lacking. In this study, we aimed to investigate whether all available P-CABs exhibit anti-inflammatory effects in gastroesophageal reflux-induced esophagitis and to elucidate the underlying mechanisms.

Background: B-cell receptor-associated protein 31 (BCAP31) is a widely expressed transmembrane protein primarily located in the endoplasmic reticulum (ER), including the ER-mitochondria associated membranes. Emerging evidence suggests that BCAP31 may play a role in cancer development and progression, although its specific effects across different cancer types remain incompletely understood.
Methods: The raw data on BCAP31 expression in tumor and adjacent non-tumor (paracancerous) samples were obtained from the Broad Institute Cancer Cell Line Encyclopedia (CCLE) and UCSC databases.

Background: Long noncoding RNAs (lncRNAs) play a critical role in gastric cancer (GC) progression and metastasis. However, research comprehensively exploring tissue-derived lncRNAs for predicting peritoneal recurrence in patients with GC remains limited. This study aims to investigate the transcriptional landscape of lncRNAs in GC with peritoneal metastasis (PM) and to develop an integrated lncRNA-based score to predict peritoneal recurrence in patients with GC after radical gastrectomy.

Purpose: Antiangiogenesis therapy has become a hot field in cancer research. Given that tumor blood vessels often express specific markers related to angiogenesis, the study of these heterogeneous molecules in different tumor vessels holds promise for advancing anti-angiogenic therapy. Previously using phage display technology, we identified a targeting peptide named GX1 homing to gastric cancer vessels for the first time.
