Three new glycosylated secondary metabolites, including a new indole alkaloid, pityriacitrin D (), and two new trehalose lipids ( and ), together with three known compounds (-) were isolated from two marine-derived bacterial strains, 168CLC-66.1 and IV19-045. The structures of - were determined by extensive analysis and comparison of their spectroscopic data with literature values. The absolute configurations of sugar moieties were determined by chemical derivatization followed by LC-MS analysis. Cytotoxicity of - against six cancer cell lines was evaluated by SRB assay, and showed moderate activity against all the tested cell lines with GI values ranging from 8.0 to 10.9 µM.

Flavonol glycosides are secondary metabolites important for plant development and stress defense such as UV-B irradiation. UDP-glycosyltransferase (UGT) catalyzes the last step in the biosynthesis of flavonol glycosides. Eriobotrya japonica is abundant in flavonol glycosides, but UGTs responsible for accumulation of flavonol glycosides remain unknown.

All Aboriginal peoples enrolled at NT Government health services, who had one or more preventable chronic conditions and were prescribed one or more oral chronic condition medications identified in the Primary Care Information System, were included in the study.

Pickering emulsion stabilized by food grade nanoparticles with stimulus response as a targeted delivery system for lipophilic bioactive compounds has attracted people's attention. In this study, ferulic acid was used to modify saccharified zein to prepare pH-sensitive nanoparticles for stabilizing Pickering emulsion. The structure, interface behavior, stability of Pickering emulsion and gastrointestinal digestion characteristics of nanoparticles in vitro were studied.

The glycomacropeptide (GMP) present in the cheese whey byproduct can be an excellent antifreezing agent due to its unique molecular structure. The objective of this study was to concentrate this peptide and investigate its ice recrystallization inhibition (IRI) ability. Heat denaturation of the non-GMP proteins and preparative liquid chromatography were used to create fraction 1 (F1) and fraction 2 (F2) and these were tested using the splat assay and a modified sucrose sandwich assay to investigate their IRI activity.
