Background: Teas and herbal infusions (THIs) are valued for their health benefits but may contain heavy metal impurities, posing health risks due to bioaccumulation and toxicity [1]. Heavy metal contamination in THIs is linked to anthropogenic sources like pollution, soil contamination, irrigation, fertilizers, and food processing equipment [2]. With the rising consumption of THIs, monitoring heavy metal contam...
Background: Intestinal barrier is an important structure that defends and maintains the homeostasis of the host. [1-3]. It is highly influenced by food due to the interaction between nutrients and gut microbiota [2]. A diet rich in sugar can disrupt gut homeostasis, leading to a dysfunctional barrier and causing chronic diseases [3]. The enterochromaffin cells (ECs) are dispersed throughout the intestine wall, ...
Background: Environmental pollution exposes human to various toxics. Food is one main route of toxic exposure, encompass pesticides, per- and polyfluoroalkyl substances (PFAS), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), metals and nanoplastics [1]. Maternal exposure is a concern due to rising childhood neurodevelopmental disorders like autism spectrum disorders (ASD) [1,2] and en...
Tramadol and tapentadol, synthetic opioids commonly prescribed for moderate-to-severe pain, have a unique pharmacology that optimizes their analgesia and safety. However, they are not devoid of risks, presenting addictive, abuse, and dependence potential. While tramadol-reinforcing properties have been documented by various studies with human and animal models, including conditioned place preference (CPP) assay...
The goal of this work was to examine whether elevated iodine intake was associated with adverse effects on IQ among school-age children in Portugal. In a representative sample of children from the north of the country, IQ percentiles by age (assessed with Raven’s Colored Progressive Matrices) were dichotomized to <50 (“below-average” IQs) and ≥50. Morning urine iodine concentrations, corrected for creatinine, w...
