Optimization of microbial cell factories for astaxanthin production: Biosynthesis and regulations, engineering strategies and fermentation optimization strategies.

The global market demand for natural astaxanthin is rapidly increasing owing to its safety, the potential health benefits, and the diverse applications in food and pharmaceutical industries. The major native producers of natural astaxanthin on industrial scale are the alga and the yeast . However, the natural production via these native producers is facing challenges of limited yield and high cost of cultivation and extraction.

Preparation of -Phenylenediamine Modified Graphene Foam/Polyaniline@Epoxy Composite with Superior Thermal and EMI Shielding Performance.

With the development of integrated devices, the local hot spot has become a critical problem to guarantee the working efficiency and the stability. In this work, we proposed an innovative approach to deliver graphene foam/polyaniline@epoxy composites (GF/PANI@EP) with improvement in the thermal and mechanical property performance. The graphene foam was firstly modified by the grafting strategy of p-phenylenediamine to anchor reactive sites for further in-situ polymerization of PANI resulting in a conductive network.

Gene Cascade Shift and Pathway Enrichment in Rat Kidney Induced by Acarbose Through Comparative Analysis.

Acarbose is an effective anti-diabetic drug to treat type 2 diabetes mellitus (T2DM), a chronic degenerative metabolic disease caused by insulin resistance. The beneficial effects of acarbose on blood sugar control in T2DM patients have been confirmed by many studies. However, the effect of acarbose on patient kidney has yet to be fully elucidated.

Integrated bioinformatics analyses identified SCL3-induced regulatory network in Arabidopsis thaliana roots.

Objectives: To uncover key genes and pathways regulated by SCL3, a GRAS transcription factor, in the context of gibberellin (GA) in the roots of the model plant Arabidopsis thaliana.

Results: Gene expression profiles of ga1-3 mutant and ga1-3 and scl3 double mutant are considerably similar to each other, revealed by Principal Component Analysis (PCA). More than 400 significantly Differentially Expressed Genes (DEGs) among the Arabidopsis thaliana roots of ga1-3 mutant, ga1-3 and scl3 double mutant and GA loss/SCL3 gain mutant were uncovered by comprehensive bioinformatics analyses.

polymerization of graphene-polyaniline@polyimide composite films with high EMI shielding and electrical properties.

With the increasing demands of the electronics industry, electromagnetic interference (EMI) shielding has become a critical issue that severely restricts the application of devices. In this work, we have proposed a "non-covalent welding" method to fabricate graphene-polyaniline (Gr-PANI) composite fillers. The Gr sheets are welded with PANI π-π non-covalent interactions.
