Development of ZmT-PEG hydrogels through Michael addition reaction and protein self-assembly for 3D cell culture.

Bioactive protein-derived hydrogels are highly attractive three-dimensional (3D) platforms for cell culture. However, most protein and polypeptide hydrogels are extracted from animal tissues or chemically synthesized, with many drawbacks. Herein, we fabricated an optically transparent ZmT-PEG hydrogel a facile one-pot strategy.

Quality evaluation of chicken soup based on entropy weight method and grey correlation degree method.

This study aimed to develop an assessment framework for evaluating the quality of different chicken soup variants. Three types of chicken soup, traditional chicken soup (TCS), concentrated chicken soup (CCS), and blended chicken soup (BCS), were prepared and analyzed for various physicochemical parameters, including gross protein content, crude fat content, pH level, solid content, viscosity, and chromatic aberration value. Sensory evaluation was also conducted to assess overall quality.

Construction and application of a multifunctional CHO cell platform utilizing Cre/ and Dre/ site-specific recombination systems.

During the development of traditional Chinese hamster ovary (CHO) cell lines, target genes randomly integrate into the genome upon entering the nucleus, resulting in unpredictable productivity of cell clones. The characterization and screening of high-yielding cell lines is a time-consuming and expensive process. Site-specific integration is recognized as an effective approach for overcoming random integration and improving production stability.
