OsWRKY49 on qAT5 positively regulates alkalinity tolerance at the germination stage in Oryza sativa L. ssp. japonica.

Integrated genome-wide association study and linkage mapping revealed genetic basis of alkalinity tolerance during rice germination. The key gene OsWRKY49 was further verified in transgenic plants. With the widespread use of the rice direct seeding cultivation model, improving the tolerance of rice varieties to salinity-alkalinity at the germination stage has become increasingly important.

Transcoronary study of biomarkers in patients with heart failure: Insights into intracardiac production.

Aims: Biomarkers are pivotal in the management of heart failure (HF); however, their lack of cardiac specificity could limit clinical utility. This study aimed to investigate the transcoronary changes and intracardiac production of these biomarkers.

Methods: Transcoronary gradients for B-type natriuretic peptide (BNP) and five novel biomarkers-galectin-3 (Gal-3), soluble suppression of tumourigenicity 2 (sST2), tissue inhibitor of metalloproteinase 1 (TIMP-1), growth differentiation factor 15 (GDF-15) and myeloperoxidase (MPO)-were determined using femoral artery (FA) and coronary sinus (CS) samples from 30 HF patients and 10 non-HF controls.

Carbon Felts Uniformly Modified with Bismuth Nanoparticles for Efficient Vanadium Redox Flow Batteries.

The integration of intermittent renewable energy sources into the energy supply has driven the need for large-scale energy storage technologies. Vanadium redox flow batteries (VRFBs) are considered promising due to their long lifespan, high safety, and flexible design. However, the graphite felt (GF) electrode, a critical component of VRFBs, faces challenges due to the scarcity of active sites, leading to low electrochemical activity.

Non-Targeted Metabolomics Analysis Reveals Metabolite Profiles Change During Whey Fermentation with .

Whey fermentation could produce bioactive substances with immunomodulatory effects, metabolic syndrome modulation, and antioxidant properties, thereby imparting functional characteristics to products and facilitating the development of novel foods with health-promoting potential. A non-targeted metabolomics approach using liquid chromatography-mass spectrometry (LC-MS) was employed to investigate changes in the metabolite profiles of whey fermented by strain KM812 over varying fermentation durations. The findings demonstrated a progressive enrichment of metabolites over time.

Characteristic Polyphenols in 15 Varieties of Chinese Jujubes Based on Metabolomics.

Background: Jujube is a homologous herb of medicine and food, and polyphenols are key in determining the functional effects of jujubes.

Methods: In this study, characteristic polyphenols in 15 varieties of Chinese jujubes were investigated based on untargeted metabolomics.

Results: The results showed that a total of 79 characteristic polyphenols were identified in the 15 varieties of Chinese jujube, and 55 characteristic polyphenols such as syringetin, spinosin and kaempferol were reported for the first time.
