Recently, colonic health has been linked to the maintaining overall health status and reducing the risk of diseases by changes in lifestyle. Functional foods, such as "prebiotics" and "probiotics", dietary fibers, and other dietary components that target the colon and affect its environment enhancing short fatty acid (SCFA) production have been at the forefront. The topic of this review is the key end products of colonic fermentation, the SCFA butyric, acetic, and propionic acids. SCFA are readily absorbed. Butyrate is the major energy source for colonocytes. Propionate is largely taken up by the liver. Acetate enters the peripheral circulation to be metabolized by peripheral tissues. Specific SCFA may reduce the risk of developing gastrointestinal disorders, cancer, and cardiovascular disesase (Fig. 1, Ref. 30). Full Text (Free, PDF) www.bmj.sk.

Exposure to vanadium (V) occurs through the ingestion of contaminated water, polluted soil, V-containing foods and medications, and the toxicity and absorption during the small intestine phase after oral ingestion play crucial roles in the ultimate health hazards posed by V. In this study, the human colon adenocarcinoma (Caco-2) cells were selected as an intestinal absorption model to investigate the uptake and cytotoxicity of vanadyl sulfate (VOSO) and sodium orthovanadate (NaVO). Our results confirmed the cytotoxic effects of V(IV) and V(V) and revealed a greater toxicity of V(IV) than V(V) towards Caco-2 cells.

Background: DNA methylation (DNAm) data from human samples has been leveraged to develop "epigenetic clock" algorithms that predict age and other aging-related phenotypes. Some DNAm clocks were trained using DNAm obtained from blood cells, while other clocks were trained using data from diverse tissue/cell types. To assess how DNAm clocks perform across non-blood tissue types, we applied DNAm algorithms to DNAm data generated from 9 different human tissue types.

Background: Obesity and metabolic syndrome are major public health concerns linked to cognitive decline with aging. Prior work from our lab has demonstrated that short-term high fat diet (HFD) rapidly impairs memory function via a neuroinflammatory mechanism. However, the degree to which these rapid inflammatory changes are unique to the brain is unknown.

Colon cancer is a significant health concern, and obesity is a well-established risk factor. However, previous studies have mainly focused on assessing body weight as a risk factor for colon cancer at a specific time point. This nationwide cohort study investigated the association between body weight changes, which can fluctuate throughout an individual's lifespan, and the incidence of colon cancer using the South Korean population database provided by the National Health Insurance Service (NHIS).

The identification of immune environments and cellular interactions in the colon microenvironment is essential for understanding the mechanisms of chronic inflammatory disease. Despite occurring in the same organ, there is a significant gap in understanding the pathophysiology of ulcerative colitis (UC) and colorectal cancer (CRC). Our study aims to address the distinct immunopathological response of UC and CRC.
