Unraveling the key structural characteristics enhancing digestion resistance of wheat starch-mung bean hull polyphenols complexes.

Mung bean hull polyphenols (MBPs) have the potential to retard starch digestion by altering its multi-scale structures. However, the regulatory mechanism and the key structural characteristics that contribute to digestion resistance remain unclear. In this study, MBPs were non-covalently interacted with wheat starch (WS) under hydrothermal treatments.

Hyaluronic acid-decorated lipid nanocarriers as novel vehicles for curcumin: Improved stability, cellular absorption, and anti-inflammatory effects.

This study aimed to investigate how hyaluronic acid interfacial decoration affects the stability, cellular absorption, and anti-inflammatory effects of curcumin-loaded nanostructured lipid carriers. Nanocarriers were synthesized with an ovalbumin single layer and ovalbumin/hyaluronic acid double, mixed, or conjugated layers. All nanocarriers were spherical (200-300 nm diameter), and their encapsulation efficiency exceeded 95 %.

Development and validation of a nomogram for individualizing fall risk in patients with hematologic malignancies.

Inpatient falls are common adverse events especially for patients with hematologic malignancies. A fall-risk prediction model for patients with hematologic malignancies are still needed. Here we conducted a multicenter study that prospectively included 516 hospitalized patients with hematologic malignancies, and developed a nomogram for fall risk prediction.

Structural characterization, physicochemical properties and hypoglycemic activity of soluble dietary fibers from salt stressed mung bean sprouts.

Low-salt stress germination is an effective way to improve the nutritional composition of food crops. A novel soluble dietary fiber (MS-SDF) was isolated from low-salt stress mung bean sprouts that were exposed to low-salt stress using anion exchange and gel permeation techniques. Structural analysis revealed that MS-SDF was a homogeneous heteropolysaccharide with an average molecular weight of 164.

Research Progress of Non-Noble Metal Catalysts for Carbon Dioxide Methanation.

The extensive utilization of fossil fuels has led to a rapid increase in atmospheric CO concentration, resulting in various environmental issues. To reduce reliance on fossil fuels and mitigate CO emissions, it is important to explore alternative methods of utilizing CO and H as raw materials to obtain high-value-added chemicals or fuels. One such method is CO methanation, which converts CO and H into methane (CH), a valuable fuel and raw material for other chemicals.

In vitro fermentation characteristics of blueberry anthocyanins and their impacts on gut microbiota from obese human.

It has been demonstrated that the gut microbiota may play an important intermediary role in anthocyanins' beneficial impacts on obesity. However, the microbe-related anti-obesity mechanism of blueberry anthocyanins remains unclear. In this study, the interactions between blueberry anthocyanin extracts (BAE) and gut microbiota from obese humans were explored using an in vitro fermentation model.

Rapid Cu(II)-Directed Self Assembly of Esterified Tea Polyphenol Oligomers to Controlled Release Nanoflower Carrier.

In this study, novel tea polyphenolic-copper hybrid nanoflowers were assembled with tea polyphenol palmitate oligomers generated simply through air oxidation. It was revealed that the growth of tea polyphenolic-based hybrid nanoflowers was notably faster than protein-based ones, presumably owing to rigid polyphenolic molecular architecture and the resultant different growth mechanism. The structures and composition investigation by FT-IR, X-ray, and SEM-EDS unveiled that the whole framework of the nanoflowers was composed of complexes of tea polyphenolic oligomers and copper phosphate crystals.

Forecasting structure of natural products through color formation process by thin layer chromatography.

With booming of computer technology, it is feasible to quantitatively extract valuable information from readily available image of objects, which dramatically reduces the cost and improves the efficiency. In this work, a structural classification method, based on data extracted from color formation process on thin layer chromatography (TLC) plates through computer processing, was established for natural products. Representative natural products exhibited good clustering and separation according to the extracted color feature, and structure of natural products can be classified by the distribution region in the color system.

Enhancement of Antioxidant Activity in O/W Emulsion and Cholesterol-Reducing Capacity of Epigallocatechin by Derivatization with Representative Phytosterols.

In this study, derivatization of epigallocatechin (EGC) by representative phytosterols (stigmasterol and β-sitosterol) was performed employing Steglich esterification. The structural identity and purity of epigallocatechin β-sitosterol (ESi) and epigallocatechin stigmasterol (ESt) were confirmed by NMR, FT-IR, and HPLC-MS. Further evaluation of ESi and ESt revealed their extraordinary antioxidant activities in O/W emulsion.

Interaction between Gemini Dodecyl O-Glucosides-Based Multilayer Vesicles and β-Lactoglobulin: The Dominant Role of Surface Charge.

Novel Gemini dodecyl O-glucoside-based primary, secondary, and tertiary vesicles were developed in this work utilizing layer-by-layer deposition of polysaccharides (e.g., sodium carboxymethyl cellulose and chitosan), and their interaction with β-lactoglobulin (BLG) was carefully investigated.

Highly effective solvent free esterification of phytosterols employing edible metal oxide-emulsifier as catalyst.

A general highly efficient solvent-free esterification of phytosterols with edible magnesium oxide and Span-60 emulsifier catalyst system has been developed. The edible emulsifier dramatically promotes the catalyzing activity of the metal oxide in the reaction. The loading of the magnesium oxide is as low as 0.
