Abstract

Gastroscopy to 35 patients with fluorosis, 32 with arsenic-fluorosis, and 25 control had been performed to study the influence of fluorosis on arsenic-fluorosis on the gastric mucosa. There was significant difference on gradient and activity of chronic gastritis among the three groups, but there was no significant difference in the fluorosis and arsenic-fluorosis [groups]. It appears that pathological changes of gastric mucosa of fluorosis and arsenic-fluorosis may be caused only by fluorosis.

  • Co-exposure to inorganic arsenic and fluoride prominently disrupts gut microbiota equilibrium and induces adverse cardiovascular effects in offspring rats.

    Highlights Co-exposure to arsenic and fluoride leads to adverse cardiovascular effects. Co-exposure to arsenic and fluoride results in gut microbiota perturbations. Co-exposure causes more prominent effects than arsenic or fluoride alone. Strong correlations are identified between cardiovascular effects and significantly altered genera. Co-exposure to inorganic arsenic (iAs) and fluoride (F-)

  • Gut microbiota perturbations and neurodevelopmental impacts in offspring rats concurrently exposure to inorganic arsenic and fluoride.

    Many “hot spot” geographic areas across the world with drinking water co-contaminated with inorganic arsenic (iAs) and fluoride (F-), two of the most common natural contaminants in drinking water. Both iAs and F- are known neurotoxins and affect neurodevelopment of children. However, very few studies have investigated the neurodevelopmental effects

  • Deregulation of autophagy is involved in nephrotoxicity of arsenite and fluoride exposure during gestation to puberty in rat offspring.

    Exposure to fluoride (F) or arsenite (As) through contaminated drinking water has been associated with chronic nephrotoxicity in humans. Autophagy is a regulated mechanism ubiquitous for the body in a toxic environment with F and As, but the underlying mechanisms of autophagy in the single or combined nephrotoxicity of F

  • Arsenic and fluoride co-exposure through drinking water and their impacts on intelligence and oxidative stress among rural school-aged children of Lahore and Kasur districts, Pakistan.

    Arsenic (As), and fluoride (F-) are potent contaminants with established carcinogenic and non-carcinogenic impacts on the exposed populations globally. Despite elevated groundwater As and F- levels being reported from various regions of Pakistan no biomonitoring study has been reported yet to address the co-exposure impact of As and F- among

  • Effect of arsenic and/or fluoride gestational exposure on renal autophagy in offspring mice.

    Highlights The exposure of fluoride and arsenic in the mother rats induced the autophagy in the kidney of the offspring mice. Under the experimental conditions, the combination of As and F showed certain antagonistic effects. The expression of autophagy negative regulator p62 is increased, which may be due to autophagic

    Gastric distress -- including nausea, pain, and vomiting -- is one the most common side effects from professional application of "fluoride gels" at the dentist.

    When fluoride has been used (at doses of 18-34 mg/day) as an experimental treatment for osteoporosis, gastric pain is one of the two main side effects consistently encountered. To better understand how fluoride causes this effect, researchers have sought to determine how fluoride affects the tissue that lines the gastrointestinal tract. In a
