[Development of the capacity to communicate risks related to childhood exposure to fluorides through an online educational strategy].

Fluorides are contaminants that occur frequently and, generally, naturally in groundwater, affecting countries that depend on these waters for irrigation and human consumption. Chronic exposure to fluorides generates various health effects; therefore, this research was based on education and risk communication to contribute to the resolution of the problem of fluoride exposure in the population. The objective was to develop the capacity to design risk communication programs for personnel involved in the response and management of environmental health risks, with emphasis on fluoride exposure.

Health Risk Assessment in Mexican Children Exposed to Fluoride from Sweetened Beverages.

The primary source of fluoride exposure is groundwater, but evidence suggests that beverages and food are additional fluoride sources. Intake of these products at an early age affects the optimal functioning of soft organs. An increase in sweetened beverage consumption by the pediatric population has been reported, suggesting an increase in fluoride exposure.

Health risk assessment in children living in an urban area with hydrofluorosis: San Luis Potosí Mexico case study.

Background: Fluoride is an inorganic element, which can be found in high concentrations in groundwater. Its consumption and exposure have consequences on human health. The objective of this study was to evaluate fluoride exposure and develop a health risk assessment in children from an urban area with hydrofluorosis in Mexico.

Application of Focused Ultrasound-Assisted Extraction for the Quantification of Persistent Organic Pollutions in Liver Tissue of Giant Toad (Rhinella marina).

A simple and rapid focused ultrasound extraction method was developed for the determination of Persistent Organic Pollutants (POPs) in liver tissue obtained of giant toad (Rhinella marina) using a gas chromatography coupled to a mass detector with electron impact ionization. The performed method for POPs, was validated in fortified matrix, showing linearity from the LOQ up to 100 ng/mL; LODs and LOQs for each compound were between 1.7 and 4.

Assessment of exposure to mixture pollutants in Mexican indigenous children.

The aim of the present work was to complete an exposure assessment in three Mexican indigenous communities using the community-based health risk assessment, which is the first step in the CHILD framework. We used 1-hydroxypyrene (1-OHP) as an exposure biomarker to polycyclic aromatic hydrocarbons (PAHs) and trans, trans-muconic acid (t,t-MA) as an exposure biomarker to benzene, persistent organic pollutants (POPs), lead, manganese, arsenic, and fluoride. Anthropometric measurements were also taken.

Effects of Heliopsis longipes ethanolic extract on mouse spermatozoa in vitro.

Context: Heliopsis longipes (A. Gray) Blake (Asteraceae), a plant native to Mexico, is used in traditional medicine as analgesic and microbicide. The main component in the H.

Effect of mining activities in biotic communities of Villa de la Paz, San Luis Potosi, Mexico.

Mining is one of the most important industrial activities worldwide. During its different stages numerous impacts are generated to the environment. The activities in the region have generated a great amount of mining residues, which have caused severe pollution and health effects in both human population and biotic components.

Analgesic activity of Heliopsis longipes and its effect on the nervous system.

Heliopsis longipes S.F. Blake (Asteraceae: Heliantheae) (chilcuague) is used in Mexican traditional medicine against parasites and to alleviate tooth and muscle pains.

Antinociceptive, genotoxic and histopathological study of Heliopsis longipes S.F. Blake in mice.

Ethnopharmacological Relevance: H. longipes S.F.

Interaction between Heliopsis longipes extract and diclofenac on the thermal hyperalgesia test.

Heliopsis longipes is an herbaceous plant found in Mexico, used traditionally for its analgesic and anesthetic activities. Plant extracts in combined use with synthetic drugs may represent a therapeutic advantage for the clinical treatment of pain, allowing the use of lower doses, and limiting side-effects. Therefore, the main objective of this study was to determine the possible pharmacological interaction between Heliopsis longipes ethanolic extract (HLEE) and diclofenac in the Hargreaves model of thermal hyperalgesia in the mouse.

Antihyperalgesia induced by Heliopsis longipes extract.

Heliopsis longipes is an herbaceous plant found in Mexico. Heliopsis longipes is traditionally used for its analgesic and anesthetic properties. Plant extracts may represent a therapeutic advantage for the clinical treatment of pain.
