Detection of Pepsin in the Sputum/Saliva for Diagnosing Atypical Manifestations of Gastroesophageal Reflux Disease
… aimed to determine whether measurement of pepsin in the sputum/saliva could be useful for diagnosing atypical GERD manifestations. METHODS: Patients with clinically suspected atypical GERD symptoms provided sputum/saliva collected before bed,at the time of symptoms,and after awakening for …

The effects of acidified pepsin on porcine vocal fold tissue: Developing a porcine model of laryngopharyngeal reflux disease
… pig tissue was challenged with acidified pepsin in different electrolyte environments to test the innate defense mechanisms of the vocal fold epithelium. From there, an <em>in vivo</em> pig model was designed to mimic the clinical situation of human LPR more closely by challenging healthy, …

Significance of variation in concentration of chlorides, acid, and pepsin, in the gastric contents, with particular reference to the control of gastric acidity
… concentration -variations of chlorides, acid and pepsin, in gastric contents, have been studied. One hundred investigations of chlorides and acid alone, and fifteen of pepsin were carried out in both normal and pathological cases. Estimations of these constituents were also performed on the …

Evaluation of several methods for detecting differences in amino acid digestibility among meat and bone meals
… among MBM samples; these were the pepsin nitrogen digestibility, the precision-fed cecectomized rooster AA digestibility, the precision-fed chick ileal AA digestibility, the standardized ileal amino acid chick digestibility, and the slope-ratio chick growth lysine bioavailability …

Investigation of the Efficacy of Various Proteinase-Treated "Serpula (Treponema) Hyodysenteriae" Vaccines
… proteinase type 2 fungal, papain proteinase, and pepsin proteinase. Sodium dodecyl sulphate polyacrylamide gel electrophoresis(SDS-PAGE) was performed on all bulk samples as well as control samples. The papain, pepsin, and proteinase K bulk samples were prepared into vaccines for use in a swine …

Design, production and characterisation of IGF-I analogues with increased gastric stability / by Katherine J. Bryant.
… determine the initial cleavage sites of purified pepsin in long-R3-IGF-I and assess whether the resulting cleavages affect biological activity, to design and produce analogues of long-R3-IGF-I which contain amino acid substitutions, to characterise the resulting analogues for pepsin resistance and …

von Willebrand factor interaction with subendothelial collagens and platelet surface receptor GPIBalpha under shear conditions
… binding between vWf multimers and human pepsin-digested collagen I, III and VI was characterized using Surface Plasmon Resonance (BIAcore). Compared to binding to pepsin-digested collagen III surfaces, normal vWf multimers (nvWf) bound to human pepsin-digested collagen I with a 5-fold …

Investigation of liquid sodium alginates as mucoadhesive bandages coating the oesophageal mucosa and protecting it from gastric reflux
… of an alginate coating to retard acid and pepsin diffusion, the two main aggressive factors in gastric reflux, was investigated. A significant reduction in acid and pepsin diffusion by alginate gel layer was demonstrated in this project, indicating that alginate has great potential to …

The impact of protein polymorphism, bovine feeding strategy and consumption temperature on the in vitro digestion behaviour of selected dairy products
… studies by developing a predictive model of pepsin activity accounting for the effect of both pH (1–6) and temperature (4–60°C) variations. This model was developed for both human pepsin and its porcine counterpart (commonly used as a substitute in vitro) based on measurements of each …

I.~Design, Synthesis, and Evaluation of a Rigidly Constrained Peptidomimetic as a Potential Type I Beta-Turn. II.~Development of Novel Estrogen Receptor Ligands With Unique Endocrine Profiles. III.~Design, Synthesis and Biological Evaluation of Potential Aspartic Protease Inhibitors Based on the Diaziridine and Diazirine Isostere
… into substrates for the aspartic protease pepsin, however they did not show any inhibition.

A Study of the Structure of Bovine Casein Micelles and the Secondary Phase of Milk Coagulation Using Immobilized Enzymes
… soluble and immobilized proteases, (chymosin and pepsin) and soluble and immobilized (neuraminidase). Analysis of the reaction products gave us an indication of the surface structure of the micelle.

Central Stimulation of the Vagi and Gastric Secretion
… a definite secretory response, high in acid and pepsin concentration, by sham-feeding a mixture of meat and water. He also showed that this response could be abolished by section of the vagi, proving that the efferent fibers conducting the impulses were located in the vagal trunk. | After the …

Evaluation of methodology for determination of availability of amino acids and energy in feedstuffs for poultry
… for poultry. In vitro assays included pepsin digestibility and lanthionine analysis. In vivo methods involved protein quality chick assay, AA bioavailability chick assay, and true AA digestibility and TMEn assay using conventional and cecectomized cockerels. Cecal retention of AA and …

Effects of Fermentation by Yeast and Amylolytic Lactic Acid Bacteria on Grain Sorghum Protein Content and Digestibility
… significant factor at 24 hours of fermentation. Pepsin digestibility of fermented samples was improved compared to thermally processed controls. Phytates increased in concentrated high-protein samples, but the ratio of phytate to protein was reduced by both yeasts. Both types of yeast increased …

Evaluation of Particle Size Differences, Calcium Sources, and Phytases on Ph and Calcium and Phosphorus Solubility in an in Vitro Simulation of Broiler Digestion
… digestion, including the addition of HCl and pepsin, with incubation times of 5, 10, or 20 min. They were also subjected to a gastric phase and a SI phase digestion, including the addition of HCl, pepsin, NaHCO3, and pancreatin with incubation times of 5, 10, 20, or 60 min. The objective of …
