Identification of crucial roles of transcription factor IhfA on high production of free fatty acids in .

Transcription factor engineering has unique advantages in improving the performance of microbial cell factories due to the global regulation of gene transcription. Omics analyses and reverse engineering enable learning and subsequent incorporation of novel design strategies for further engineering. Here, we identify the role of the global regulator IhfA for overproduction of free fatty acids (FFAs) using CRISPRi-facilitated reverse engineering and cellular physiological characterization.

Improved Stability and In Vitro Anti-Arthritis Bioactivity of Curcumin-Casein Nanoparticles by Ultrasound-Driven Encapsulation.

Curcumin possesses beneficial biological functions, namely anti-inflammation and anti-diabetic functions. However, due to its low solubility and crystallinity, its applications are limited. In this work, curcumin was encapsulated in casein micelles in order to form curcumin-casein nanoparticles by ultrasound treatment (5 min).

Superior anti-infective potential of eugenol-casein nanoparticles combined with polyethylene glycol against infections.

The aim of this study was to improve the stability of eugenol-casein nanoparticles (EL-CS-NPs) through polyethylene glycol (PEG) modification. The results show that modifying the EL-CS-NPs with PEG after loading with eugenol (EL) gives PEG-EL-CS-NPs, with increased stability. The NPs modified with higher-molecular-weight PEG showed better stability.

Triterpenic Acids from Potentilla parvifolia and Their Protective Effects against Okadaic Acid Induced Neurotoxicity in Differentiated SH-SY5Y Cells.

Six triterpenic acids were separated and purified from the ethyl acetate extractive fraction of ethanol extracts of Potentilla parvifolia FISCH. using a variety of chromatographic methods. The neuroprotective effects of these triterpenoids were investigated in the present study, in which the okadaic acid induced neurotoxicity in human neuroblastoma SH-SY5Y cells were used as an Alzheimer's disease cell model in vitro.
