Studies on Ovalbumin. III. Denaturation of Ovalbumin and S-Ovalbumin [PDF]

open access: yesAustralian Journal of Biological Sciences, 1968
Ovalbumin and S-ovalbwnin have been compared by measuring their viscosity and optical rotatory dispersion in aqueous formamide solutions at pH 7 and in urea solutions at pH 3·5; also by measuring the optical rotatory dispersion of heated solutions at different salt concentrations, and by a study of ultraviolet differlilnce spectra in alkylamine ...

Studies on Ovalbumin. IV. Trypsin Digsestion and the Cystine Peptides of Ovalbumin and S-Ovalbumin [PDF]

open access: yesAustralian Journal of Biological Sciences, 1968
Conditions for obtaining comparable tryptic digests of denatured, alkylated ovalbumin and S-ovalbumin have been studied. The tryptic peptides soluble at pH 4 -5 were fractionated by gel filtration in 1 % formic acid. The cystine-peptide fraction was resolved into two cystine peptides by chromatography on DEAESephadex, and by amino acid analyses these ...

Studies on Ovalbumin II. The Formation and Properties of S-Ovalbumin, a More Stable Form of Ovalbumin [PDF]

open access: yesAustralian Journal of Biological Sciences, 1965
Ovalbumin is changed to a more stable form (S-ovalbumin) during the storage of shell eggs. Conversion also occurs in an isolated ovalbumin solution, the rate increasing with pH and temperature. First order rate constants for the reaction have been measured at pH 9-10 and at temperatures between 20 and 50°C.

Thermostability of Refolded Ovalbumin andS-Ovalbumin

open access: yesBioscience, Biotechnology, and Biochemistry, 2005
Ovalbumin, a member of the serpin superfamily, is transformed into a thermostabilized form, S-ovalbumin, during storage of shell eggs or by an alkaline treatment of the isolated protein (DeltaT(m)=8 degrees C). As structural characteristics of S-ovalbumin, three serine residues (Ser164, Ser236 and Ser320) take the D-amino acid residue configuration ...

Echinochrome Ameliorates Physiological, Immunological, and Histopathological Alterations Induced by Ovalbumin in Asthmatic Mice by Modulating the Keap1/Nrf2 Signaling Pathway

open access: yesMarine Drugs, 2023
Asthma is a persistent inflammatory disease of the bronchi characterized by oxidative stress, airway remodeling, and inflammation. Echinochrome (Ech) is a dark-red pigment with antioxidant and anti-inflammatory activities.

Induction of Thymic Stromal Lymphopoietin Production by Nonanoic Acid and Exacerbation of Allergic Inflammation in Mice

open access: yesAllergology International, 2013
Background: Thymic stromal lymphopoietin (TSLP) plays critical roles in the induction and exacerbation of allergic diseases. We tested various chemicals in the environment and found that xylene and 1,2,4-trimethylbenzene induced the production of TSLP in

Effects of Flavin7 on allergen induced hyperreactivity of airways

open access: yesEuropean Journal of Medical Research, 2009
Some studies have suggested that the polyphenolic compounds might reduce the occurrence of asthma symptoms. The aim of our experiments was to evaluate the effects of 21 days of the flavonoid Flavin7 administration on experimentally induced airway ...
