Recent advances of rodent models for alcoholic liver disease in evaluating healthy effects of food bioactive ingredients

引用

Food Science and Human Wellness 2024年

作者： Xiaoting Yu Xuedi zhang lijuan zhang Haitao Wang Mingqian Tan State Key Lab of Marine Food Processing & Safety Control Dalian Polytechnic University Academy of Food Interdisciplinary Science School of Food Science and Technology Dalian Polytechnic University National Engineering Research Center of Seafood Dalian Polytechnic University Engineering Research Center of Seafood of Ministry of Education of China Dalian Polytechnic University

The development of rodent models that accurately reflect the pathogenesis of alcoholic liver disease (ALD) in humans is crucial for evaluating the nutritional intervention of food bioactive ingredients in ALD. Although various models have been employed to establish ALD models over the past few decades， most successful cases are associated with high mortality rates， operational difficulties， and incompatibility formation mechanism compared to human ALD. However， the ALD models established by oral administration that simulate human drinking behavior often fail to induce significant liver damage. Therefore， it is imperative to explore simple and effective modes of oral administration for establishing ALD models consistent with the pathophysiological process of human ALD. Herein， we summarized the pathogenesis of ALD and discussed several issues related to construct ALD models with rodents (mainly mice and rats) by oral administration， including animal selection， animal feeding， alcohol intervention， and evaluation criteria. The purpose of this review is to provide a standardized and efficient formula for ALD modeling， so as to facilitate efficacy evaluation and mechanism analysis of food bioactive ingredients in ALD.

Contemporary World 2024年第1期 12-16页

作者： zhang lijuan the Institute of National Governance at the Shandong University

The restructuring of global industrial and supply chains is a hot issue in today’s world,and as a result of the once-in-a-century changes and intensified geopolitical and economic competition,the demand for global industrial and supply chain security has risen sharply,with government departments and transnational corporations(TNCs)becoming the most critical stakehold*** carefully calibrate industrial and trade policies from the perspective of national strategies to create industrial chains that support national competitive advantages,and multinational corporations respond to geopolitical risks by prioritizing industrial and supply chain security and sustainability over capital and *** the backdrop of changes unseen in a century,decelerating globalization and global economic downturn,the characteristics and future trends of global industrial and supply chain restructuring are worth paying attention to.

Mitochondria-targeted nanoparticles for encapsulating astaxanthin: exploring the reason for alleviating oxidative damage

引用

Food Science and Human Wellness 2024年

作者： Yannan Chen Siyuan Fei lijuan zhang Mingqian Tan Academy of Food Interdisciplinary Science School of Food Science and Technology Dalian Polytechnic University National Engineering Research Center of Seafood Dalian Polytechnic University Collaborative Innovation Center of Seafood Deep Processing Dalian Polytechnic University

Oxidative stress is considered as a critical factor in the process of pathological diseases， and mitochondria are considered as vital target organelles for disease intervention. The purpose of this study was aimed to evaluate the antioxidant efficacy of mitochondria-targeted astaxanthin nanoparticle on hydrogen peroxide-induced oxidative damage. As expected， mitochondria-targeted nanoparticle showed excellent mitochondria co-localization ability with higher Pearson’s correlation coefficient (R=0.88). In vitro experiments suggested that the mitochondria-targeted astaxanthin nanoparticle could promote cell viability and increase antioxidant-related enzyme activities. Simultaneously， metabolomics analysis indicated that mitochondria-targeted astaxanthin nanoparticle could alleviate oxidative stress by regulating amino acid metabolism and energy metabolism. Altogether， all these results strongly confirmed the mitochondria-targeted strategy for astaxanthin delivery could relieve oxidative stress and had great promise in the application of disease intervention.
