Initially, an enhanced logistic population growth model, derived from the Lotka-Volterra model, was developed to examine the broader ecological implications of lamprey influence. This involved integrating a logistic growth model into the traditional Lotka-Volterra framework to simulate the inhibitory impact of intrapopulation competition on population growth. The phase diagram with asymptotically stable fixed points further illustrates the advantage of lampreys using sex ratios to maintain population stability. Notably, distinctions in the survivability and resource-consuming capacity between male and female lampreys were considered by incorporating varying parameter values. The study posits that extreme sex ratios could lead to lamprey population extinction, while a balanced sex ratio correlates with a significant reduction in lamprey prey organisms within a larger ecological context.","PeriodicalId":147629,"journal":{"name":"Highlights in Science, Engineering and Technology","volume":"8 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141808038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, research has been directed towards effective preservation techniques and monitoring methods to address this challenge. This review delves into advancements in fish preservation and freshness monitoring, highlighting the perishable nature of fish owing to its protein content. It examines post-slaughter quality and structural changes in fish meat, recent preservation methods including physical methods and packaging approaches, and proposes a theoretical framework for further development in fish preservation and freshness assessment. Key areas of focus include sensory quality changes, pH value, water-holding capacity, thiobarbituric acid reactive substance value, TVB-N value, structural changes post-slaughter, stress-related muscle metabolism alterations, enzymatic myofibrillar proteolysis, and lipid impacts on fish quality. Additionally, the review discusses preservation methods like physical treatments, ultrasound, modified atmosphere packaging, vacuum packaging, and active packaging, along with monitoring techniques such as sensory bionic technology and spectroscopy technology for assessing fish freshness.","PeriodicalId":147629,"journal":{"name":"Highlights in Science, Engineering and Technology","volume":"22 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141806267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among many processed foods, artificial sweeteners have been favored by consumers all over the world because of their low calories and high sweetness. However, with the deepening of the research on artificial sweeteners, there are continuous research on artificial sweetness. The medicine is not a completely healthy food. Through rat experiments and clinical experiments, researchers from all over the world have verified that ingestion of artificial sweeteners not only promotes drug resistance mutations in human cells, but may also affect the human central nervous system, thus interfering with the normal metabolic process of the human body, eventually causing toxic damage to brain tissue and damage to the hippocampus. Xi and memory, obesity, diabetes, hypercholesterolemia and other metabolic syndromes. In addition to the above adverse effects, there are also research results that show that the intake of aspartame is related to cancer, but the research in this regard has not reached a definite conclusion, so the final result is still controversial, and further clinical trial verification results are needed. This article has sorted out the current evidence that eating artificial sweeteners may have adverse effects on the human body, hoping to provide relevant scholars and consumers with a more objective and rational new perspective, so as to consider the intake of artificial sweeteners more carefully.","PeriodicalId":147629,"journal":{"name":"Highlights in Science, Engineering and Technology","volume":"40 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141809757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many studies have shown that sex differentiation in sea lamprey is influenced by external environmental factors, making it dependent on and also influencing the surrounding ecosystem. This article focuses on studying the impact of this sexual variation on the species itself and the surrounding ecosystem. Using differential equations, based on reality, this article constructed a cellular automaton model and a variant Lotka-Volterra model incorporating three species. This article comprehensively applied software programming tools such as MATLAB to solve these models. By building the model, obtained the general operation of lamprey ecosystem and the reproduction and evolution of lamprey population. This article primary aim is to investigate the sex ratio of species and its dependence on and impact on local environmental conditions. This article aim to understand how organisms within this ecosystem interact and adapt to environmental changes. Furthermore, this article seek to understand how sex ratio is influenced during upstream spawning migrations, and whether this dynamic change in sex ratio has ecological adaptive significance.","PeriodicalId":147629,"journal":{"name":"Highlights in Science, Engineering and Technology","volume":"57 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141809771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alpha-glucosidase inhibitors are the first choice for the treatment of type II diabetes. However, the widely used AGI in clinical practice often has varying degrees of side effects. Plant polysaccharide is a kind of active substance that widely exists in plants and has great potential to alleviate diabetes. Screening of plant polysaccharides with hypoglycemic effects has attracted much attention due to efficient health care ability and good biocompatibility. This article focused on plant polysaccharides with α-glucosidase inhibitory activity, systematically elaborated on the hypoglycemic effect of plant polysaccharides, and provided a detailed review on the effects of extraction and purification methods on the physicochemical properties of plant polysaccharides and the activity of α-glucosidase inhibitors, as well as the researches on improving the AGI inhibitory abilities of plant polysaccharides through modification.
