A device that can easily measure elec. impedance might be a helpful tool for investigating the pathophysiol. of gastroesophageal reflux disease. The first aim of this study was to validate our newly developed bioelec. admittance measurement (BAM) through in vitro experimentation. The second aim was to investigate whether evaluation of BAM by this measurement differed between patients with heartburn according to their response to proton pump inhibitor (PPI) therapy. Caco-2 cell monolayers and three-dimensional tissues were examined by BAM using a frequency response analyzer. BAM was also used to measure the impedance through cell layers. Subsequently, BAM was performed during endoscopy in 41 patients experiencing heartburn without esophageal mucosal breaks. After 2-wk administration of 20-mg rabeprazole twice daily, patient responses to PPI were classified as “good” or “poor” according to their clin. course. In each patient, histol. alterations and gene expression levels of inflammation mediators and tight junction proteins were evaluated. Impedance profiles indicated that monolayer Caco-2 cells on top of eight-layered normal human dermal fibroblasts had the highest magnitude of impedance over the range of frequencies. In vivo results revealed that patients with good responses to PPI displayed significantly higher admittance. Severity of low-grade inflammation was significantly associated with esophageal wall admittance. Moreover, esophageal wall admittance may be more closely related to basal zone hyperplasia than dilatation of intercellular spaces. Thus, BAM may be able to detect abnormalities in the subepithelial layer of the esophagus. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Application of 117976-90-6).
Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Application of 117976-90-6
