Quantitative, standardized assays for determining the concentrations of bovine lactoperoxidase, human salivary peroxidase, and human myeloperoxidase.

TL;DR: A review of the use of the lactoperoxidase (LP) system in the dairy industry can be found in this article, where new research findings and developments made so far and potential applications of the LP system in other food systems and commercial products are discussed.

TL;DR: C. accolens modifies its local habitat in vitro as it inhibits growth of Streptococcus pneumoniae by releasing antibacterial free fatty acids from host skin surface triacylglycerols, and lays the foundation for future in vivo studies to determine whether habitat modification by C. accolENS could be promoted to control pathogen colonization.

TL;DR: The findings suggest that the profound antioxidant capacity of saliva secreted from parotid glands is related either to the different physiological demands related to eating, to oral integrity maintenance, or to the high content of deleterious redox-active transitional metal ions present in parotsid saliva.

TL;DR: The data suggest that the LPO system is a major contributor to airway defenses, and may have significant implications for chronic airway colonization seen in respiratory diseases such as cystic fibrosis.

TL;DR: Investigation of substrate and inhibitor specificity, pH optimum, chromatography on Sephadex G-200, disc electrophoresis, ultraviolet absorption spectrum and the effects of temperature and ionic strength variation are described.

TL;DR: The mechanisms of H2O2 reduction is shown by analysis of the structural changes observed in the intermediates, and a correlation is shown between the ratio of peaks in the low k (ligand field indicator ratio) region, the Fe-Np average distance, and the magnetic susceptibility, which provides a sensitive indicator of spin state.

TL;DR: An assay for total peroxidase activity in saliva is developed, based on the rate of formation of hypochlorite, which is not affected by the concentrations of thiocyanate found in saliva.
