Effects of sweet potato starch on the physicochemical properties and edible qualities of instant fresh rice noodles.

Instant fresh rice noodles (IFRNs) on the market suffer from issues such as undesirable gel hardness and poor extensibility after high-temperature sterilization and rehydration, significantly compromising their mechanical properties and overall edibility. This research aimed to improve the quality of IFRNs by incorporating sweet potato starch (SPS) into rice flour. The physiochemical properties and multi-scale structural properties of the IFRNs with SPS were then characterized by differential scanning calorimetry, texture profile analysis, wide-angle X-ray diffraction, Fourier transform infrared spectroscopy, small-angle X-ray scattering, and scanning electron microscopy.

Bulk Stereoselective Cationic Polymerization of Vinyl Ethers by the Coordination of ZrCl with Tunable Spirocyclic Phosphoric Acids.

Control over stereochemistry in poly(vinyl ether)s leads to a notable change in their physical properties, yet remains a grand challenge. Here, we demonstrate the bulk stereoselective cationic polymerization of vinyl ethers using ZrCl coordinated with a spirocyclic phosphoric acid (SPA). The widely variable substituents in SPAs exert a profound impact on the stereochemical and activity outcome of the polymerization: the % m of poly(vinyl ether)s linearly increases with the Hammett substituent constant (σ) of SPAs; the catalytic activity increases with the σ; the large steric hindrance groups lead to decreased polymerization activity.

Platelet Activation-Induced In Situ Trapping Metastatic Tumor Cells Strategy for Post-Surgery Tumor Recurrence Immunochemotherapy.

The reasons for the high recurrence and metastasis after triple-negative breast cancer (TNBC) surgery are the potential presence of micrometastases and disseminated tumor cells in the circulation, as well as the immunosuppressive microenvironment caused by the surgery.

To utilize the targeting ability of PLTs toward tumor cells and maintain the activity of PLTs, doxorubicin-loaded nanoparticles (NP) were attached on the surface of PTLs (NP-PLT).

Enhancing the gel properties of soy protein isolate: the role of oxidized konjac glucomannan in acid-induced gelation.

Background: Soy protein isolate (SPI) gels formed using a single coagulant often have poor water-holding capacity (WHC) and low hardness, making them fragile and unsuitable for transportation and storage. Adding compound coagulants or polysaccharides can improve the gelation properties of SPI gels induced by gluconolactone (GDL). This study explores the impact of oxidized konjac glucomannan (OKGM) on the physicochemical and structural properties of GDL-induced SPI gels, with the aim of evaluating the potential of OKGM for enhancing the overall quality and stability of these gels.

Theoretical study on ligand conformational self-adaptation for modulating reactivity.

The combination of Josiphos-type ligands with Pd catalysts has been instrumental in the rapid development of efficient catalytic processes. We performed density functional theory (DFT) calculations to elucidate the mechanisms and dynamic conformational changes responsible for the reactivity and selectivity observed in Pd-catalysed bicyclization/carbonylation of 1,6-enynes. DFT calculations indicated that the most favourable reaction pathway involves an unusual alkene insertion into the carbon-palladium bond to give high level of enantioselectivity.

Case report: A case study of neoadjuvant immunochemotherapy for locally advanced esophageal squamous carcinoma.

In locally advanced esophageal cancer, the controversy over the two traditional treatment modalities, neoadjuvant radiotherapy and neoadjuvant chemotherapy, has been unending and also challenged by the addition of neoadjuvant immunotherapy. Neoadjuvant immunotherapy has led to an increasing diversity of neoadjuvant combination treatment modalities, among which neoadjuvant immunochemotherapy has emerged, with current clinical studies initially demonstrating its efficacy and safety. We report a case of a patient with locally advanced esophageal cancer who underwent two cycles of neoadjuvant immunochemotherapy and successful surgery and achieved a pathological complete response (pCR).
