Summary: Dietary pulses, such as dry beans and lentils, are a good source of fiber and can easily be incorporated into regular diets to improve gut health. The resistant starch derived from pulses plays a crucial role in shaping the gut microbiota and promoting metabolic health. However, more research is needed to explore the potential benefits of pulses and their resistant starch on aging-associated gut health.

Summary: This study investigates the effects of resistant dextrin derived from potato starch on the growth of gastrointestinal microbiota and the activity of fecal enzymes. The results show that resistant dextrin can promote the growth of beneficial strains of gut bacteria and reduce the growth of other intestinal strains. Moreover, it affects the activity of fecal enzymes to a certain extent and does not significantly change the pH of the cultures.

Summary: Increasing the inclusion of agricultural co-products in poultry feed to utilize nutrients at a low cost also increases the dietary fiber content, leading to challenges. The use of enzymes, advancements in feed processing, and specialized feed formulations have helped improve digestibility, though high dietary fiber remains an issue. Techniques like breaking down fiber into fermentable substrates with enzymes or using prebiotics and probiotics show promise in enhancing gut health and growth performance in poultry.

Summary: The study determined the molecular structure and properties of cassava-derived resistant maltodextrins (RMDs), finding that prolonged dextrinization increased the indigestibility and dietary fiber content of RMDs. RMDs had a higher proportion of beta-glycosidic linkages and low molecular weight dietary fiber compared to their RD counterparts.

Summary: Dietary fiber intake is closely related to the health of the gut microbiota, and a decrease in dietary fiber intake may contribute to the global epidemic of metabolic disorders such as obesity and type 2 diabetes. The effects of dietary fiber on the gut microbiota are specific to the type, amount, and duration of intake. Understanding the interaction between dietary fiber and the gut microbiota can provide insights for optimal intervention strategies for patients.

Summary: The gut microbiota (GMB) in humans plays a crucial role in health and diseases. Dietary fibers, such as β-glucans (BGs), can regulate the composition and function of GMB and have therapeutic effects on gut health. There is increasing interest in commercial application of BGs as a bioactive substance in food formulations. This review aims to consider the metabolizing and effects of BGs on GMB, as well as their influence on gut infections, prebiotic effects, fermentation, and processing.

Summary: The study focuses on the F-Minor-Free Deletion problem, particularly on the Outerplanar Deletion problem as a special case. By leveraging the combinatorial properties of outerplanar graphs, the researchers present elementary reduction rules to decrease the size of a graph, resulting in a constructive kernel with O(k^4) vertices and edges. Additionally, any minor-minimal obstruction to having an outerplanar deletion set of size k is shown to have O(k^4) vertices and edges.

Summary: In this study, the parameterized complexity of various classic vertex-deletion problems is investigated, with a focus on FPT algorithms that can simultaneously consider solution size and treewidth as parameters. By introducing new classes of parameterizations and a framework for computing approximately optimal decompositions, efficient algorithms for solving vertex-deletion problems are developed. This research provides valuable insights into parameterized complexity theory and algorithm design for graph problems.
