Comprehensive review of dysphagia and technological advances in dysphagia food.

As the global population ages, dysphagia is becoming increasingly common among the elderly, posing serious risks such as choking, aspiration pneumonia, and even death. Leveraging advanced technologies to develop specialized food products for those with dysphagia not only serves the economic interests of the elderly food market but also significantly enhances the nutritional health and social satisfaction of this demographic. This review examines the causes and early symptoms of dysphagia, the development of texture-modified foods (TMFs), and the relevant regulations and standards.

Photocatalytic rice bran protein/carboxymethyl cellulose/ZrO fiber produced by microfluidics: Formation mechanism, bacteriostasis and strawberry preservation.

Developing cost-effective and environmentally sustainable active packaging materials remains an important challenge. We have developed rice bran protein (RBP)-based fibers incorporating carboxymethyl cellulose (CMC) and ZrO nanoparticles (ZrO NPs, 0 %-7 %, m/m) using microfluidic spinning. The integration of RBP, CMC, and ZrO NPs formed a robust hydrogen bond network that enhanced the fibers' thermal stability and crystallinity, reduced surface hydrophobicity, and aligned the molecular orientation.

Anemoside B4 attenuates abdominal aortic aneurysm by limiting smooth muscle cell transdifferentiation and its mediated inflammation.

Abdominal aortic aneurysm (AAA) is a degenerative disease characterized by local abnormal dilation of the aorta accompanied by vascular smooth muscle cell (VSMC) dysfunction and chronic inflammation. VSMC dedifferentiation, transdifferentiation, and increased expression of matrix metalloproteinases (MMPs) are essential causes of AAA formation. Previous studies from us and others have shown that Anemoside B4 (AB4), a saponin from , has anti-inflammatory, anti-tumor, and regulatory effects on VSMC dedifferentiation.

[Mechanism of Puerariae Thomsonii Radix in treatment of mild dyslipidemia: based on clinical metabolomics and proteomics].

This study aims to explore the potential metabolic pathways and targets of Puerariae Thomsonii Radix in the clinical treatment of mild dyslipidemia. UPLC-Q-TOF-MS and EASY-nLC-timsTOF-Pro2 were employed to perform metabolomic and proteomic analyses of the plasma samples collected from the patients with mild dyslipidemia at baseline and after 12 weeks of treatment with Puerariae Thomsonii Radix. The multivariate statistical analysis was carried out for comparison between groups, and the correlation analysis was performed for the metabolites and proteins closely related to mild dyslipidemia with the blood lipid indexes.
