Regulating effects of low salt dry-curing pre-treatment on microbiota, biochemical changes and flavour precursors of grass carp () fillets during storage at 4 °C.

Low salt dry-curing (LSD), as a healthier pre-treatment for the preservation of fishery products, is a potential technique substitute for excessively salty curing. The regulatory effects of 2 % and 3 % LSD on the quality evolution through an intrinsic correlation between microbiota succession and flavour precursors of refrigerated grass carp fillets were investigated in this study. The results showed that the LSD pre-treatment was effective in promoting proteolysis, free amino acid and fatty acid metabolism with the microbiota succession and quality evolution.

An Integrated Method of Biomechanics Modeling for Pelvic Bone and Surrounding Soft Tissues.

The pelvis and its surrounding soft tissues create a complicated mechanical environment that greatly affects the success of fixing broken pelvic bones with surgical navigation systems and/or surgical robots. However, the modeling of the pelvic structure with the more complex surrounding soft tissues has not been considered in the current literature. The study developed an integrated finite element model of the pelvis, which includes bone and surrounding soft tissues, and verified it through experiments.

Methionine restriction constrains lipoylation and activates mitochondria for nitrogenic synthesis of amino acids.

Methionine restriction (MR) provides metabolic benefits in many organisms. However, mechanisms underlying the MR-induced effect remain incompletely understood. Here, we show in the budding yeast S.

Enzymolysis Reaction Kinetics and Liquid Chromatography High-Resolution Mass Spectrometry Analysis of Ovalbumin Glycated with Microwave Radiation.

Microwave radiation was adopted to accelerate glycation between ovalbumin (OVA) and d-glucose. We evaluated the digestibility of glycated OVA from the perspective of kinetics, using pepsin and trypsin as model enzymes. Hydrolysed protein concentrations, enzymolysis kinetics, and activation energy () were investigated.
