Concentration-dependent Activation of Inflammatory/Anti-inflammatory Functions of Macrophages by Hydrolyzed Whey Protein.

Background/aim: Whey protein is a mixture of globulins isolated from whey and mainly composed of β-lactoglobulin, α-lactoalbumin, and lactoferrin. In this study, whey protein was hydrolyzed using various proteases, and the macrophage activation was evaluated.

Materials And Methods: Hydrolyzed whey protein was prepared using various proteases to evaluate phagocytic activity and cytokine productivity.

Rapid and Accurate Identification of Animal Species in Natural Leather Goods by Liquid Chromatography/Mass Spectrometry.

The demand for leather goods has grown globally in recent years. Industry revenue is forecast to reach $91.2 billion by 2018.

Peptide Profiling Using Matrix-Assisted Laser Desorption/Ionization-Time-of-Flight Mass Spectrometry for Identification of Animal Fibers.

Identification of fibers for verification of their specific animal origin is necessary for maintaining quality and value in the clothing industry. In order to examine adulteration in animal fibers, there is a commercially accepted method of microscopy analysis. However, this method is subjective and time-consuming due to its reliance on an operator identifying magnified fibers from their scale image and other features.

Synthesis and structural revision of phomopsin B, a novel polyketide carrying a 10-membered cyclic-ether ring.

Total synthesis of the proposed structure 2 for phomopsin B was achieved by using an intramolecular olefin metathesis as a key step. The spectral data, however, did not match with those of the natural product reported. Re-examination of the reported NMR data led to the structural revision of phomopsin B to known dothiorelone A 18.
