Abstract Many plant foods are rich sources of rutin, a flavonoid with many biological activities and health benefits. Exposure to cadmium has been implicated in neurotoxicity and cognitive dysfunction in animal models. However, there is a dearth of information on the effect of rutin on the cadmium bioavailability in the brain of rats exposed to cadmium. Thus, the present study investigated the therapeutic efficacy of rutin in an animal model of cognitive impairment via alterations of cadmium bio...

Abstract Objective The compositions of the gut microbiota and its metabolites were altered in individuals with Autism Spectrum Disorder (ASD). The aim of this study was to assess whether plasma levels of gut-derived metabolite trimethylamine N-oxide (TMAO) were associated with ASD and the degree of symptom severity. Methods From September 2017 to January 2019, a total of three hundred and twenty-eight Chinese children (164 with ASD and 164 their age-sex matched control subjects) aged 3–8 years w...

Abstract Background Occupational studies have shown an association between elevated Mn exposure and depressive symptoms. Blood Mn (BMn) naturally rises during pregnancy due to mobilization from tissues, suggesting it could contribute to pregnancy and postpartum depressive symptoms. Objectives To assess the association between BMn levels during pregnancy and postpartum depression (PPD), creating opportunities for possible future interventions. Methods We studied 561 women from the reproductive lo...

Abstract Evidence of structural abnormalities in the nervous system of recreational drug [e.g., phencyclidine (PCP) or ketamine] users and/or preclinical animal research models suggests interference with the activity of multiple neurotransmitters, particularly glutamate neurotransmission. The damage to the central nervous system (CNS) may include neuronal loss, synaptic changes, disturbed neural network formation and reduced projections to subcortical fields. Notably, the reduced projections may...

Abstract There is a need for in vitro tests for the evaluation of chemicals and pharmaceuticals that may cause developmental neurotoxicity (DNT) in humans. The neural embryonic stem cell test (ESTn) is such an in vitro test that mimics early neural differentiation. The aim of this study was to define the biological domain of ESTn based on the expression of selective markers for certain cell types, and to investigate the effects of two antidepressants, fluoxetine (FLX) and venlafaxine (VNX), on n...

Abstract Objectives Epidemiology studies indicated that coke-oven workers with long-term exposure to polycyclic aromatic hydrocarbons (PAHs) often have some neurobehavioral abnormalities especially impairment for cognitive function, while the underlying mechanisms are not fully understood. Numerous studies have indicated the antioxidant and anti-apoptosis roles of heat shock protein 70 (Hsp70). The genetic polymorphisms in HSP70 genes are associated with multiple diseases including neurotoxicity...

Abstract Environmental pollution due to arsenic is associated with several adverse health effects including neurotoxicity in animals and humans. Selenium is a nutritionally essential trace metalloid well documented to elicit compelling pharmacological activities in vitro and in vivo. Report on the influence of selenium on arsenic-mediated behavioral derangement is lacking in literature. Hence, to fill this knowledge gap, rats were either exposed to arsenic per se in drinking water at 60 μg AsO2N...

Abstract Contamination in estuarine regions affects the local biota damaging the ecosystems and reaching humans. The gastrointestinal tract is a dynamic environment capable of obtaining nutrients and energy from food while it protects the host against harmful toxins and pathogens from the external environment. These functions are modulated by the enteric nervous system and changes in its structure can result in gastrointestinal disorders. The objective of this study was to evaluate if the enviro...

Abstract Epidemiological data have linked cadmium exposure to neurotoxicity and to neurodegenerative diseases (e.g., Alzheimer’s and Parkinson’s disease), and to increased risk of developing ALS. Even though the brain is not a primary target organ, this metal can bypass the blood brain barrier, thus exerting its toxic effects. The coordination chemistry of cadmium is of strong biological relevance, as it resembles to zinc(II) and calcium(II), two ions crucial for neuronal signaling. A toxicogeno...
