Interaction behavior between five flavonoids and pepsin: Spectroscopic analysis and molecular docking

, 2021
Baicalin, myricetin, rutin, hesperidin and isoliquiritin are five classic flavonoids. Being both dietary and biologically active compounds, the accurate and full basic data for clarifying the binding mechanisms of the five flavonoids to pepsin remain ...

The interaction of Naphthol Yellow S (NYS) with pepsin: Insights from spectroscopic to molecular dynamics studies.

International Journal of Biological Macromolecules, 2020
The effects of Naphthol Yellow S (NYS) on the structure and activity of pepsin were carried out using ultraviolet-visible (UV-Vis) spectroscopy, intrinsic fluorescence spectroscopy, circular dichroism (CD), thermal stability, kinetic techniques, as well ...

Structure and physical properties of gelatin from bovine bone collagen influenced by acid pretreatment and pepsin

, 2020
Effects of different acids and pepsin on the properties of gelatins extracted from bovine bone collagen were investigated. Pretreatment of bovine bone by different acids (hydrochloric acid, acetic acid, and citric acid) with and without pepsin was ...

Correlation of salivary and nasal lavage pepsin with MII‐pH testing

The Laryngoscope, 2020
Laryngopharyngeal reflux (LPR) is a common upper airway disease. Salivary pepsin is a proposed marker for LPR; however, the optimal time for collection of specimens for pepsin detection and pepsin's presence in the oral and nasal secretions relative to ...

Interactions of Surface-Functionalized Starch Nanoparticles with Pepsin and Trypsin in Simulated Gastrointestinal Fluids.

Journal of Agricultural and Food Chemistry, 2020
Nanoparticles (NPs) can form a protein corona (PC) with proteins in biological fluids. We examined whether starch nanoparticles (SNPs) form a PC and interact with digestive enzymes in simulated gastric and intestinal fluids.

Diagnostic Utility of Salivary Pepsin as Compared With 24-Hour Dual pH/Impedance Probe in Laryngopharyngeal Reflux

Otolaryngology Head & Neck Surgery, 2020
Objective Laryngopharyngeal reflux (LPR) is defined as the retropulsion of gastric contents into the larynx, oropharynx, and/or nasopharynx. The 24-hour combined hypopharyngeal-esophageal multichannel intraluminal impedance with dual pH probe (24h-HEMII ...

RNA Sequencing Reveals Cancer‐Associated Changes in Laryngeal Cells Exposed to Non‐Acid Pepsin

The Laryngoscope, 2020
Laryngopharyngeal reflux (LPR) is a common affliction that contributes to laryngeal inflammation, symptoms that impact quality of life, and life‐threatening illnesses such as cancer. Effective treatment strategies for LPR are lacking.

Pepsin in gastroesophageal and extraesophageal reflux: molecular pathophysiology and diagnostic utility

Current Opinion in Otolaryngology & Head and Neck Surgery, 2020
Purpose of review Gastroesophageal and extraesophageal reflux are prevalent and costly diseases. Recognition of the pathogenicity of nonacid reflux has stimulated interest in alternatives to acid-targeting diagnostics and therapeutics. Pepsin is the most

Extraction and characterization of pepsin-solubilized collagen from snakehead (Channa argus) skin: Effects of hydrogen peroxide pretreatments and pepsin hydrolysis strategies

Process Biochemistry, 2019
The effects of hydrogen peroxide (H2O2) pretreatments and pepsin hydrolysis strategies on the extraction of pepsin-solubilized collagen (PSC) from the skin of snakehead (Channa argus) were studied. The dependences of H2O2 bleaching on H2O2 concentrations
