Summary: This study reveals that the combination of microbiota and high-fat diet may suppress the expression of hepatocyte nuclear factor 4 alpha, leading to the preferential activation of intestinal epithelial cell proliferation programs, which in turn affects intestinal lipid absorption, epithelial cell renewal, and systemic energy balance.

Summary: Research demonstrates that Stevia rebaudiana's response to light conditions affects the accumulation of antioxidant-like metabolites in its leaves, possibly linked to total phenolic content. Variations in SOD activity among plants under different photoperiods suggest a synergistic interaction between SOD isoforms and phenolic compounds to mitigate oxidative stress caused by light exposure.

Summary: This study investigated the possible interactions of the brain-exercise-intestine-microbiome axis. The results showed that voluntary exercise could increase endurance capacity and spatial memory, but had no significant effect on gastrointestinal motility and intestinal oxidative stress levels. Additionally, voluntary exercise increased the number of caveolae in the smooth muscles of the intestine and the relative abundance of Bifidobacteria in the microbiome, which correlated with Akt levels in the intestine.

Summary: The study of the gut microbiome is crucial for understanding and treating metabolic diseases. While research on the fecal microbiome has provided valuable insights, relying solely on this may not be enough to draw comprehensive conclusions. The microbiome in the proximal part of the small intestine may play a significant role in metabolic regulation, but further exploration is needed due to limited accessibility.

Summary: The review highlights the importance of studying the microbial communities in the small intestine, which has been largely overlooked compared to the fecal microbiota. It provides an overview of methods for studying the composition and dynamics of the small intestinal microbiota and discusses its role in maintaining physiological functions and the development of diseases. Understanding and characterizing the small intestinal microbiota has the potential to advance gut microbiome research and the development of diagnostic and therapeutic approaches for diseases.

Summary: Fermented food consumption affects the composition and functionality of the small intestinal microbiome. The introduction of product-derived bacteria significantly influences the overall microbial community, but has no significant effects on SCFA levels, GI permeability, and the endogenous microbial community. The impact on microbiome composition is highly personalised and a specific bacterial family, Peptostreptococcaceae, is positively associated with a low abundance of the ingested bacteria.

Summary: Postharvest sweetening can improve the eating quality of sweetpotato, particularly of immature sweetpotato. The sucrose content increased at all temperatures, while glucose and fructose mainly increased at 4 degrees C. The study suggests that IbVIN1 could be a candidate gene in cultivating sweetpotato varieties high in sweetness.

Summary: The study observed that acute immune stress resulted in increased inflammatory cytokines and genes involved in de novo steroidogenesis and corticosterone regeneration in the intestine, with reduced response in germ-free mice. The interaction between stress and the microbiota did not impact plasma corticosterone levels or adrenal steroidogenic enzymes.

Summary: This study aimed to assess the excretion of aspartame in saliva and the levels of salivary insulin, total protein, and alpha amylase in response to the intake of sweetened beverages. The results showed that artificially sweetened drinks and beverages with sucrose left a lingering sweet/sour residual flavor in saliva, and saliva aspartame levels were only correlated with insulin levels after the intake of diet soft drinks.

Summary: High-fat diet-induced dysbiosis in the small intestine leads to pathological changes in the luminal environment, disruption of small-intestinal mucosal integrity, and minimal inflammation in the gut-liver axis, ultimately resulting in the development of steatohepatitis in mice.

Summary: Gastrointestinal stromal tumor (GIST) is a rare small intestinal tumor that is often difficult to diagnose, leading to long-term complaints. This study retrospectively analyzed all small intestinal GIST patients who underwent surgery at Mansoura University Gastrointestinal Surgical Center between January 2008 and May 2021.

Summary: The iron reducing enrichment obtained from sulfate reducing sludge was evaluated for reducing Fe3+ coupled to acetate oxidation in a microbial fuel cell (MFC). Different molar ratios of acetate/Fe3+ resulted in varying percentages of Fe3+ reduction and current densities in the MFC, showing the involvement of multiple mechanisms and bacteria in acetate utilization and Fe3+ reduction.

Summary: The aim of this study was to evaluate the effect of different concentrations of gelatin, whey protein, and chitosan on the properties of composite edible films and optimize their formulation for food packaging. The results showed that the independent variables significantly affected the water vapor permeability, strength, and solubility of the edible films. The optimized formulation resulted in smooth and transparent films with lower water vapor permeability, maximum strength, and lower solubility.

Summary: Actinobacteria, particularly Streptomyces, Saccharopolyspora, and Micromonospora, are widely used bacteria in producing industrial compounds due to their biosynthetic capability. Molecular techniques and bioinformatics programs have been developed to aid in the discovery of new natural products in actinobacteria. Rare actinobacteria such as Nocardia and Rhodococcus have been found to produce new industrial compounds through these techniques.

Summary: The genotoxic potential of mercury and its derivatives remains controversial, with organic mercury compounds being more toxic than inorganic and elemental ones but all still posing a potential risk. There is not sufficient evidence for mercury to be classified as a human carcinogen. Studies have shown that inorganic mercury compounds such as mercury chloride and mercury nitrate, and organic compounds like methylmercury and thimerosal, are widely studied in populations with accidental, occupational, or iatrogenic exposure.
