Successful treatment of small bowel phytobezoar using double balloon enterolithotripsy combined with sequential catharsis: A case report.

Background: Small bowel bezoar obstruction (SBBO) is a rare clinical condition characterized by hard fecal masses in the small intestine, causing intestinal obstruction. It occurs more frequently in the elderly and bedridden patients, but can also affect those with specific gastrointestinal dysfunctions. Diagnosing SBBO is challenging due to its clinical presentation, which mimics other intestinal obstructions.

Mutational Landscape of Gastric Adenocarcinoma of the Fundic Gland Type Revealed by Whole Genome Sequencing.

Background: Gastric adenocarcinoma of the fundic gland type (GA-FG) is a newly described variant of gastric adenocarcinoma with lack of knowledges regarding its genetic features.

Methods: We performed whole-genome sequencing (WGS) in formalin-fixed paraffin-embedded (FFPE) tumor tissues and matched adjacent noncancerous specimens from 21 patients with GA-FG, and integrated published datasets from 1105 patients with traditional gastric adenocarcinoma with the purpose of dissecting genetic determinants both common to conventional gastric adenocarcinoma and unique to GA-FG disease.

Results: We characterized the genomic architecture of GA-FG disease, revealing the predominant proportion of C > T substitution among the six types of SNVs.

Identification and experimental verification of senescence-related gene signatures and molecular subtypes in idiopathic pulmonary arterial hypertension.

Evidences illustrate that cell senescence contributes to the development of pulmonary arterial hypertension. However, the molecular mechanisms remain unclear. Since there may be different senescence subtypes between PAH patients, consistent senescence-related genes (SRGs) were utilized for consistent clustering by unsupervised clustering methods.

β-sitosterol alleviates pulmonary arterial hypertension by altering smooth muscle cell phenotype and DNA damage/cGAS/STING signaling.

Background: Pulmonary arterial smooth muscle cells (PASMCs) have a neoplastic phenotype characterized by hyperproliferative and anti-apoptotic features that contribute to pulmonary hypertension (PH) development. DNA-sensing adapter protein stimulator of interferon genes (STING) regulate the phenotypic switch of vessel smooth muscle cells. β-sitosterol (SITO) is a nutrient derived from plants that inhibits vascular smooth muscle cell proliferation without notable toxicity.

Y4 RNA fragments from cardiosphere-derived cells ameliorate diabetic myocardial ischemia‒reperfusion injury by inhibiting protein kinase C β-mediated macrophage polarization.

The specific pathophysiological pathways through which diabetes exacerbates myocardial ischemia/reperfusion (I/R) injury remain unclear; however, dysregulation of immune and inflammatory cells, potentially driven by abnormalities in their number and function due to diabetes, may play a significant role. In the present investigation, we simulated myocardial I/R injury by inducing ischemia through ligation of the left anterior descending coronary artery in mice for 40 min, followed by reperfusion for 24 h. Previous studies have indicated that protein kinase Cβ (PKCβ) is upregulated under hyperglycemic conditions and is implicated in the development of various diabetic complications.
