Dietary Compounds in the Prevention of Arsenic Induced Intestinal Toxicity .
J Med Food
January 2025
Instituto de Agroquímica y Tecnología de Alimentos (IATA-CSIC), Paterna (Valencia), Spain.
Recent studies show that inorganic arsenic (As) exerts a toxic effect on the intestinal epithelium, causing a significant increase in its permeability. This disruption of the epithelial barrier may favor the entry of contaminants or toxins into the systemic circulation, thus causing toxicity not only at the intestinal level but possibly also at the systemic level. The present study conducts an evaluation of the protective effect of various dietary supplements and plant extracts against the intestinal toxicity of inorganic As.

Prior work highlighted that procrastination and impulsivity shared a common neuroanatomical basis in the dorsolateral prefrontal cortex, implying a tight relationship between these traits. However, theorists hold that procrastination is motivated by avoiding aversiveness, while impulsivity is driven by approaching immediate pleasure. Hence, exploring the common and distinct neural basis underlying procrastination and impulsivity through functional neuroimaging becomes imperative.

Nanoporous graphene (NPG), laterally bonded carbon nanoribbons, is a promising platform for controlling coherent electron propagation in the nanoscale. However, for its successful device integration NPG should ideally be on a substrate that preserves or enhances its anisotropic transport properties. Here, using an atomistic tight-binding model combined with nonequilibrium Green's functions, we study NPG on graphene and show that their electronic coupling is modulated as a function of the interlayer twist angle.

Impairment of gut barrier integrity is associated with the pathogenesis of gastrointestinal diseases, including inflammatory bowel disease, colorectal cancer, and coeliac disease. While many aspects of diet have been linked to improved barrier function, (poly)phenols, a broad group of bioactive phytochemicals, are of potential interest. The (poly)phenolic sub-class, flavan-3-ols, have been investigated in some detail owing to their abundance in commonly consumed foods, including grapes, tea, apples, cocoa, berries, and nuts.

Inflammatory bowel disorders (IBD) can lead to severe complications like perforation, bleeding, and colon cancer, posing life-threatening risks. Murray ( Murr.), rich in polysaccharides, has been utilized in traditional diets for thousands of years.
