The Effect of Ultrasound Treatment on the Structural and Functional Properties of Myofibrillar Protein.

The objective of this study was to explore the impacts of various ultrasonic powers (0, 300, 500, 700, and 900 W) on the structure and functional attributes of the myofibrillar protein (MP) of . As the ultrasonic intensity escalated, the extraction efficiency and yield of the MP rose, while the particle size and turbidity decreased correspondingly. The reduction in sulfhydryl group content and the increase in carbonyl group content both suggested that ultrasonic treatment promoted the oxidation of the MP to a certain extent, which was conducive to the formation of a denser and more stable gel network structure.

Sodium butyrate alleviates pre-eclampsia in pregnant rats by improving the gut microbiota and short-chain fatty acid metabolites production.

Aims: Pre-eclampsia (PE) affects pregnant patients worldwide, but there is no effective treatment for this condition. We aimed to explore the effect of sodium butyrate (NaB) on PE.

Methods And Results: In this study, Nω-nitro-L-arginine methyl ester hydrochloride was used to induce PE in pregnant rats.

[Identification of interacting proteins with NF-κB in different status of uterine smooth muscle in labor].

To analyze the differentially expressed proteins which interacted with NF-kappaB in the uterine lower segment smooth muscle tissues under different status of labor onset, and to provide a new foundation on the mechanisms for labor onset.
 Methods: NF-κB P65 protein expression in smooth muscle tissues from the term non-labor group, natural term labor group and drug-induced term labor group was analyzed by Western blot. Co-immunoprecipitation and SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) were performed to detect the proteins interacting with NF-κB p65 in the NF-κB p65 complexes.
