Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Safety Assessment and Hypoglycemic Effect of Moringa oleifera Lam. Seed Lectin (WSMoL) in Alloxan‐Induced Diabetic Mice

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Moringa oleifera Lam. seeds contain WSMoL, a lectin previously studied for toxicity and pharmacological effects. In this study, we investigated WSMoL (10, 25, or 50 mg/kg i.p.) for acute and 14‐day repeated‐dose toxicity, as well as genotoxicity, in Swiss mice.

Parental Exposure to Nanoplastics and Graphene Oxide Induces Transgenerational Toxicity in Caenorhabditis elegans

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Environmental pollution by emerging contaminants such as nanoplastics (NPs) and graphene oxide (GO) represents a growing threat to global health and ecosystems. This study investigated the effects of parental exposure, both isolated and combined, to 100 μg/L NPs (polystyrene, spherical, 100 nm) and 100 mg/L GO, using Caenorhabditis elegans as ...

Black flesh disorder in mango: a chilling injury symptom increased by early harvest and low storage temperature and reduced by 1‐methylcyclopropene

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Black flesh (BF) is an internal disorder in mango, characterized by the development of dark brown to black pigmentation in the inner mesocarp tissue during storage or transport. This study investigated the effects of harvest maturity, low storage or low transport temperatures, and 1‐methylcyclopropene (1‐MCP) on mango fruit ...
