Summary: Diabetes mellitus is a complex disorder that requires lifelong dependence on glucose-lowering drugs. The advent of oral peptide drugs, such as semaglutide, brings hope to patients with chronic diabetes. This review summarizes the anti-diabetic activities and mechanisms of peptides from legumes and discusses the prospects of these peptide-based drugs in type 2 diabetes management.

Summary: Legume grains are important sources of essential nutrients in human diets. In addition, they contain non-nutrients with interesting bioactive properties, such as antioxidant, hypoglycemic, hypolipidemic, and anticarcinogenic effects. However, there is a lack of sufficient data to determine the ideal amount of these non-nutrients and their specific health benefits, which calls for further studies to define recommended levels and optimize dietary strategies.

Summary: "Expression of Cre recombinase by AtRps5a(pro) or AtDD45(pro) enabled precise transgene activation in hybrid cowpea and tobacco, but limitations were observed with AtUbq3(pro) restricting ZsGreen expression. Overcoming this limitation was achieved by driving ZsGreen expression with the AtUbq10 promoter, while using AtDD45(pro) to express Cre resulted in varying recombination frequencies between transgenic lines and crosses."

Summary: Acetamiprid (ACE) and cyromazine (CYR) are frequently used pesticides in cowpea growing areas in Hainan. This study investigated their uptake, translocation, subcellular distribution, and metabolic pathway in cowpea. The results showed that both pesticides were mainly distributed in leaves, and their subcellular distribution was primarily in the cell soluble fraction. Metabolic reactions such as dealkylation, hydroxylation, and methylation were observed. The dietary risk assessment revealed that while ACE is safe, CYR poses an acute risk to infants and young children.

Summary: Consumption of plant foods, specifically those high in dietary fiber, is associated with improved health outcomes and reduced risk of chronic diseases. Different types of fiber provide different health benefits based on their properties and effects. Plant foods also contain bioactives that contribute to their health benefits. The concept of soluble fiber as a sole determinant of physiological effects is outdated. Recent research shows that insoluble dietary fiber intake is associated with various health benefits beyond increased stool weight. It is suggested that ancestral humans consumed high amounts of dietary fiber, which also delivered bioactives that are crucial for disease prevention. Therefore, isolated fiber supplements may have limited usefulness unless accompanied by bioactives.

Summary: Ethyl methane sulfonate (EMS) was used to induce genetic variability in cowpea, resulting in unique agro-morphological abnormalities such as leaf color, shape, growth habit, pod curvature, seed shape, and seed coat color. This research highlights the importance of EMS mutagenesis for breeding and developing new farmer preferred varieties.

Summary: This study investigated the combining ability and genetic correlations for water deficit tolerance traits in cowpea. The results showed the presence of additive and non-additive gene action, with additive genes playing a predominant role. Several genotypes were identified as good general combiners for traits related to yield and water deficit tolerance. The study also identified specific combiners for water deficit tolerance traits. The heritability of traits such as days to pod maturity, pod length, number of pods per plant, and weight of hundred seeds was found to be high.

Summary: This study investigated the effects of iron and boron on the yield and yield attributes of cowpea planted at different sowing times in the Ordu region of Turkey. The results showed that the combined use of seed treatment with iron, boron, and specific sowing time significantly increased the yield and yield attributes of cowpea. However, the highest dose of boron (600 g da1) resulted in decreases in these properties. The best results were observed with the interaction of 2 kg da1 iron dose, 300 g da1 boron dose, and sowing time on May 15th.

Summary: Sorghum grain has higher levels of resistant starch (RS) and slowly digestible starch (SDS), which can have positive health effects if the endosperm structure is not disrupted during processing. Thermally induced cross-linking and tannins contribute to the low starch digestibility. However, high-shear technologies disrupt the structure, making the starch fully digestible. Further research is needed to understand the mechanisms and interactions between intrinsic and processing factors related to RS in sorghum foods.

Summary: This study investigated the anthocyanin profiles of pigmented flower extracts from Geraniaceae and Lamiaceae plant species in South Africa, and assessed their thermal and oxidative stability. Lamiaceae pigments showed higher thermal and oxidative stability, potentially due to aromatic malonyl-acylated anthocyanin self-association and strong interactions with phenolic acids and derivatives.

Summary: The study found that increasing the proportion of OFSP flour in maize flour extruded pasta increased cooking loss but decreased cooking time and water absorption capacity. The dietary fiber in OFSP flour loosened the compact structure of the pasta, disrupting the protein-starch matrix of maize and resulting in higher cooking loss and sticky pasta. Extruded pasta had shorter cooking time due to pre-gelatinized starch and exhibited better water absorption and heat dissemination during cooking.

Summary: Functional foods have been developed in response to consumers' increasing demand for healthier food options. This study investigated the effects of lactic acid fermentation and exogenous acidification on non-alcoholic gruels made from sorghum and amaranth in terms of their phenolic content and antioxidant capacities. The results showed that both fermentation and acidification significantly increased the total phenolic content, flavonoid content, and radical scavenging capacities of the gruels. This suggests that souring cereal-based foods through fermentation or acidification could potentially provide protection against illnesses related to oxidative stress.
