Prediction of individual total amino acids and free amino acids in Chinese Holstein cows milk using mid-infrared spectroscopy and their phenotypic variability.

Establishing a high-throughput detection technology for amino acid (AA) content in milk using mid-infrared (MIR) spectroscopy has profound implications for enhancing nutritional value of milk, identifying superior milk sources, producing specialty dairy products, and expanding Dairy Herd Improvement (DHI) metrics. The aim of this study was to evaluate the effectiveness of MIR spectroscopy in predicting the content of 15 individual total AA (TAAs) and 16 free AA (FAAs) in bovine milk as well as to investigate the major factors affecting the phenotypic variability of AA content. From March 2023 to March 2024, 513 milk samples were collected from 10 Holstein dairy farms in China and analyzed using Bentley spectrometers for MIR measurements.

Novel Eel Skin Fibroblast Cell Line: Bridging Adherent and Suspension Growth for Aquatic Applications Including Virus Susceptibility.

Suspension growth can greatly increase the cell density and yield of cell metabolites. To meet the requirements of aquatic industries, a culture model derived from skin was developed using the explant outgrowth and enzyme-digesting passaging methods. These cells were kept in vitro continuously for over 12 months and subcultured 68 times.

Interaction between interleukin-12 (IL-12) and its receptor (IL-12Rβ2) mediates CD4 T cell subsets activation in flounder (Paralichthys olivaceus).

Interleukin-12 (IL-12) regulates the differentiation of CD4 T lymphocytes into Th1 cells by binding to its receptor, thereby promoting cellular immunity. This study characterized IL-12 and its receptor β2 (IL-12Rβ2) in flounder (Paralichthys olivaceus) and investigated their interaction, effects on T cell proliferation and differentiation, and the adjuvant effects of IL-12. The recombinant IL-12 was successfully expressed, and the IL-12Rβ2 antibody was confirmed to specifically recognize IL-12Rβ2.

Epilepsy and brain health: a large prospective cohort study.

Background: Epilepsy, as a chronic noncommunicable disease with recurrent seizures, may be a marker of deterioration or alteration in other underlying neurological diseases. This study aimed to investigate the relationship of epilepsy with brain function, other common brain disorders, and their underlying mechanisms.

Methods: The study was based on clinical diagnostic and test data from 426,527 participants in the UK Biobank, of whom 3,251 were diagnosed with epilepsy at baseline.

Proton-Transfer Dynamics Regulates CO Electroreduction Products via Hydrogen Coverage.

Electrochemical conversion of CO to hydrocarbons is a promising approach to carbon neutrality and energy storage. The formation of reaction intermediates involves crucial steps of proton transfer, making it essential to understand the role of protons in the electrochemical process to control the product selectivity and elucidate the underlying catalytic reaction mechanism of the CO electrochemical reduction (CORR). In this work, we proposed a strategy to regulate product selectivities by tuning local proton transport rates through a surface resin layer over cuprous oxides.
