Cardiac fibrosis is a chronic inflammatory response that considerably impacts cardiac function following myocardial infarction (MI). Although Plumbagin, a natural compound, has been shown to have anti-fibrotic effects by suppresses the ROS and NF-κB pathways in liver fibrosis, its role in regulating cardiac function and cardiac fibrosis post-MI remains unknown. In this study, we demonstrate that Plumbagin effectively inhibits TGF-β1-induced myocardial fibroblast fibrosis and promotes autophagy activation by suppressing the AKT/mTOR pathway.

Article Synopsis
  • Intestinal barrier damage and oxidative stress are key issues in ulcerative colitis (UC), and this study investigates the effects of fucoidan from Stichopus chloronotus (FucSc) on UC caused by dextran sulfate sodium (DSS).
  • The research showed that FucSc treatment improved the integrity of intestinal cells, boosted protective proteins, and activated antioxidant pathways, helping cells resist oxidative damage.
  • Additionally, when administered orally, FucSc reduced symptoms like weight loss and colon damage in UC, highlighting its potential as a beneficial dietary supplement for managing colitis.

(HP) infections affect approximately one-third of children worldwide. In China, the incidence of HP infection in children ranges from approximately 30% to 60%. In addition to damaging the gastrointestinal tract mucosa, HP infection in children can negatively affect their growth and development, hematology, respiratory and hepatobiliary system, skin, nutritional metabolism, and autoimmune system.

Background: With the continuous innovation of magnetic resonance imaging (MRI) hardware and software technology, amide proton transfer-weighted (APTw) imaging has been applied in liver cancer. However, to our knowledge, no study has evaluated the feasibility of a three-dimensional amide proton transfer-weighted (3D-APTw) imaging sequence for hepatocellular carcinoma (HCC). This study thus aimed to conduct an image quality assessment of 3D-APTw for HCC and to explore its feasibility.

Meropenem is an ultrabroad-spectrum antimicrobial agent that is often recommended for the treatment of bacterial meningitis (BM) in children. However, a subtherapeutic phenomenon occurred in BM children complicated with augmented renal clearance (ARC) at the recommended dose of meropenem. To support its pharmacokinetics, a sensitive, fast and robust ultra-liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed to measure meropenem concentrations in serum and cerebrospinal fluid (CSF).

Background: Liver cancer is a highly lethal and aggressive form of cancer that poses a significant threat to patient survival. Within this category, liver hepatocellular carcinoma (LIHC) represents the most common subtype of liver cancer. Despite decades of research and treatment, the overall survival rate for LIHC has not significantly improved.

Objective: To differentiate gastric leiomyomas (GLs) and gastric stromal tumors (GSTs) based on preoperative enhanced computed tomography characteristics.

Methods: Twenty-six pathologically confirmed GLs were propensity score-matched to 26 GSTs in a 1:1 ratio based on sex, age, tumor site, and tumor size. Tumor shape and contour, mucosal ulceration, growth pattern, enhancement pattern and degree, longest diameter, and longest diameter/vertical diameter ratio were compared between the groups.

Insulin and incretin-based drugs are important antidiabetic agents with complex effects on cell growth and metabolism. Emerging evidence shows that insulin and incretin-based drugs are associated with altered risk of biliary tract cancer (BTC). Observational study reveals that insulin is associated with an increased risk of extrahepatic cholangiocarcinoma (ECC), but not intrahepatic cholangiocarcinoma (ICC) or gallbladder cancer (GBC).
