Quality improvements of reconstituted noodles by pre-hydrating gluten: Insights at different levels.

Reconstituted noodles containing multi-grain are superior to plain noodles in terms of health benefits, but their lower gluten levels cause deterioration in cooking performance and textural quality. To this end, this study investigated the efficacy of gluten pre-hydration in a model dough. The results indicated that, with the increase in the ratio of pre-hydrated gluten, the final hydration level of gluten in reconstituted noodles, the proportion of ordered secondary structures of gluten, and the intensities of molecular interactions continuously increased, resulting in a more compact gluten network.

Tailoring industrial enzymes for thermostability and activity evolution by the machine learning-based iCASE strategy.

The pursuit of obtaining enzymes with high activity and stability remains a grail in enzyme evolution due to the stability-activity trade-off. Here, we develop an isothermal compressibility-assisted dynamic squeezing index perturbation engineering (iCASE) strategy to construct hierarchical modular networks for enzymes of varying complexity. Molecular mechanism analysis elucidates that the peak of adaptive evolution is reached through a structural response mechanism among variants.

Enabling High-Performance Multi-Resonant TADF Emitters via Intramolecular Hydrogen Bond.

Hydrogen bonds (HBs), prevalent strong interactions in organic compounds, can effectively constrain single bond rotation, leading to rigid planar configurations. This rigidity enhances emission efficiency and narrows the emission spectrum of luminescent materials. Recent advances have leveraged HBs to advance high-performance donor-acceptor thermally activated delayed fluorescence (TADF) materials.

The application of monoglycerides to improve the quality of fresh noodles: Discerning the roles of acyl chain length and dispersity.

Monoglycerides are widely used in flour-based products, but the roles of their dispersibility and acyl chain length remain unclear. This study investigated the effects of monoglycerides with different chain lengths (C12, C16, C18) dispersed in deionized water (DW) or 95 % ethanol (EE) on fresh noodle quality. Ethanol (2 mL per 200 g flour) had no significant effect on noodle properties, but monoglycerides in EE significantly altered gluten structure through covalent and non-covalent interactions, forming a denser gluten network, as observed by CLSM.

The impact of JC viruria on renal transplant recovery and prognosis.

Postoperative JC viruria is common in kidney transplant recipients, however there remains a dearth of research on perioperative JCV infection in this population. The clinical significance of JCV monitoring in kidney transplant recipients remains unclear. Based on JCV urine monitoring during the perioperative phase, renal transplant recipients who underwent perioperative and postoperative monitoring at our center were categorized into two groups: the perioperative JC virus infection group and the control group consisting of recipients without detectable JCV DNA in plasma or urine during the two-year follow-up period.

Efficient metal free organic radical scintillators.

The development of high-performance metal-free organic X-ray scintillators (OXSTs), characterized by a synergistic combination of robust X-ray absorption, efficient exciton utilization, and short luminescence lifetimes, poses a considerable challenge. Here we present an effective strategy for achieving augmented X-ray scintillation through the utilization of halogenated open-shell organic radical scintillators. Our experimental results demonstrate that the synthesized scintillators exhibit strong X-ray absorption derived from halogen atoms, display efficacious X-ray stability, and theoretically achieve 100% exciton utilization efficiency with a short lifetime (∼18 ns) due to spin-allowed doublet transitions.

Rapid and ultra-sensitive trace water determination in organic solvents utilizing nitrobenzoxadiazole (NBD)-based fluorescent sensing system.

The presence of minute quantities of water in organic solvents can affect the progress of many reactions and cause unnecessary losses and even safety accidents in the chemical industry, especially in the productions process of organic fine chemicals. Therefore, it is necessary to carry out high-performance strategies for trace water detections in commonly used organic solvents. In this work, a fluorescent sensing system based on competitive binding of protons has been developed, demonstrating remarkable responses by UV-vis absorption and fluorescence two-modes toward a trace amount of water in organic solvents including 1,4-dioxane (Diox), tetrahydrofuran (THF), acetonitrile (MeCN), acetone (ACE), dimethylsulfoxide (DMSO) and mixed organic solvents (THF: MeCN=1: 1).

Pre-IVM with C-type natriuretic peptide promotes mitochondrial biogenesis of bovine oocytes via activation of CREB.

The aim of this study was to evaluate the effects of C-type natriuretic peptide (CNP) treatment prior to in vitro maturation (IVM) on mitochondria biogenesis in bovine oocyte matured in vitro and explore the related causes. The results showed that treatment with CNP before IVM significantly improved mitochondrial content, elevated the expression of genes related to mitochondria biogenesis, and increased the protein levels of phosphorylation of cAMP-response element binding protein (p-CREB) in bovine oocytes following IVM. However, further studies revealed that treatment with CNP before IVM could not increased the protein levels of p-CREB in bovine oocytes when natriuretic peptide receptor 2 activities was inhibited using the relative specific inhibitor Gö6976.
