Protective effects of organoselenium compounds against methylmercury-induced oxidative stress in isolated mitochondria

, 2013
Introduction and aims: Methylmercury is a highly neurotoxic environmental contaminant. Despite classical chelating therapies, there is no effective treatment available for methylmercury poisoning. In this stydy, we evaluated the potential neuroprotective

Assessment of developmental neurotoxicity induced by chemical mixtures using an adverse outcome pathway concept

Environmental Health, 2020
Background In light of the vulnerability of the developing brain, mixture risk assessment (MRA) for the evaluation of developmental neurotoxicity (DNT) should be implemented, since infants and children are co-exposed to more than one chemical at a time ...

Guidelines for High‐Throughput Screening for Natural Products With Anti‐Aging Activity Based on Drosophila Intestinal Homeostasis

AgriFood: Journal of Agricultural Products for Food, Volume 2, Issue 3, Page 221-231, September 2026.
ABSTRACT Aging represents a critical risk factor for chronic diseases, driving an urgent demand for interventions promoting healthy longevity. This study establishes standardized guidelines for high‐throughput screening (HTS) of anti‐aging natural products using Drosophila melanogaster, leveraging its intestinal homeostasis as a biomarker.

Cytotoxicity and genotoxicity of low doses of mercury chloride and methylmercury chloride on human lymphocytes in vitro

Brazilian Journal of Medical and Biological Research, 2005
Mercury is a xenobiotic metal that is a highly deleterious environmental pollutant. The biotransformation of mercury chloride (HgCl2) into methylmercury chloride (CH3HgCl) in aquatic environments is well-known and humans are exposed by consumption of ...

Assessment of water quality and emerging pollutants in two fish species from the mallorquin swamp in the Colombian Caribbean

Heliyon
The Mallorquín Swamp, an important ecosystem in Atlántico, Colombian Caribbean, underwent environmental monitoring at eight points during rainy, transition, and dry seasons. This was to assess water quality, seasonal variation, and the bioaccumulation of

Gaschromatographic determination of methylmercury compounds from samples containing sulfide

BUNSEKI KAGAKU, 1970
硫化物を含む試料中のメチル水銀化合物をガスクロマトグラフィーで定量する場合,硫化物による妨害を防ぐため,塩化第二水銀を試料に添加する方法が従来用いられていた.しかし,本研究の結果,塩化第二水銀の一部は有機溶媒で抽出され,また塩化第二水銀がメチル塩化水銀と混在すると,得られたピークはメチル塩化水銀,塩化第二水銀それぞれ単独のピークの和よりも増大したので,塩化第二水銀の添加は適当でない.硫化物はメチル水銀化合物をビス-硫化ジメチル水銀に変化させ,グルタチオンあるいはシステイン処理では抽出できなかったので,塩化第一銅を試料に添加してビス-硫化ジメチル水銀を完全にメチル塩化水銀の形に変化させたのちに抽出,ガスクロマトグラフィーにより定量を行なったところ好結果を得た.塩化銀はビス ...

Mercury and selenium relationship in a tropical estuarine fish

Frontiers in Marine Science, 2015
Aquatic systems have been considered as final sinks for persistent and bioaccumulative toxicants (PBTs), such as metals and organohalogen compounds. Among the trace elements, non-essential metals deserve special attention due to their toxicity.

Does Health Information Matter for Modifying Consumption?, October 2006 [PDF]

, 2006
A field experiment was conducted in France to evaluate the impact of health information on fish consumption. A warning given to the treatment group revealed the risks of methylmercury contamination in fish and also gave consumption recommendations. Using

Health Information and the Choice of Fish Species: An Experiment Measuring the Impact of Risk and Benefit Information, April 2006 [PDF]

, 2006
An experiment was conducted in France to evaluate the impact of health information on consumers’ choice between two different types of fish. Successive messages revealing risks (methylmercury) and benefits (omega-3s) of consuming the fish, along with ...
