    • Sun, 05/15/2022 - 04:00
    • Fish & Shellfish Immunology
    • As a kind of environmental pollutant, heavy metal Cadmium (Cd) exists widely in the environment. It is well known that Cd can accumulate and cause damage in liver, kidney and other organs. However, there are few studies on the immune cytotoxicity of Cd to fish. In particular, there are few studies on the toxicity of Cd to the head kidney lymphocytes of common carp. In order to further explore these mechanisms, we established an Cd exposure model in vitro.

    • Frontiers in Plant Science
    • The toxic heavy metal cadmium (Cd) is easily absorbed and accumulated in crops and affects human health through the food chains. Sunflower (Helianthus annuus L.) is a globally important oil crop. In this study, two sunflower cultivars 62\3 (high Cd) and JB231AC (low Cd), were chosen to compare physiological and transcriptomic responses at different Cd concentrations (0, 25, 50, and 100 μM). The results showed that JB231AC had better Cd tolerance than 62\3.

    • Fri, 05/06/2022 - 04:00
    • Frontiers in Plant Science
    • Potentially toxic elements (PTEs) such as cadmium (Cd), lead (Pb), chromium (Cr), and arsenic (As), polluting the environment, pose a significant risk and cause a wide array of adverse changes in plant physiology. Above threshold accumulation of PTEs is alarming which makes them prone to ascend along the food chain, making their environmental prevention a critical intervention. On a global scale, current initiatives to remove the PTEs are costly and might lead to more pollution.

    • Frontiers in Plant Science
    • Mosses are one of the earliest diverging land plants that adapted to living on land. The BURP domain-containing proteins (BURP proteins) are plant-specific proteins that appeared when plants shifted from aquatic environments to land. Phylogenetic analysis revealed that the BURP domain of higher plants is originated from lower land plants and divergent because of motif conversion.

    • Fri, 05/06/2022 - 04:00
    • Toxicology and Industrial Health
    • Amiodarone (AMD) is an antiarrhythmic drug that induces idiosyncratic toxicity. Environmental pollutants, including heavy metals, could interact with its toxicity by affecting pharmacokinetics and pharmacodynamics. Other levels of interaction could exist in yeast, such as oxidative stress and the general stress response. In this study, we investigated the interaction of mercury chloride (HgCl2) and cadmium chloride (CdCl2) with AMD toxicity on Saccharomyces cerevisiae.
