Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

Chemistry &Biodiversity, EarlyView.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Cocktails of Mycotoxins, Phytoestrogens, and Other Secondary Metabolites in Diets of Dairy Cows in Austria: Inferences from Diet Composition and Geo-Climatic Factors

Toxins, 2022
Dairy production is a pivotal economic sector of Austrian and European agriculture. Dietary toxins and endocrine disruptors of natural origin such as mycotoxins and phytoestrogens can affect animal health, reproduction, and productivity.

Mycotoxin occurrence in maize silage : a neglected risk for bovine gut health? [PDF]

, 2019
Forages are important components of dairy cattle rations but might harbor a plethora of mycotoxins. Ruminants are considered to be less susceptible to the adverse health effects of mycotoxins, mainly because the ruminal microflora degrades certain ...

The mycotoxin alternariol induces DNA damage and modify macrophage phenotype and inflammatory responses [PDF]

Toxicology Letters, 2015
Alternariol (AOH), a mycotoxin produced by Alternaria fungi, is frequently found as a contaminant in fruit and grain products. Here we examined if AOH could modify macrophage phenotype and inflammatory responses. In RAW 264.7 mouse macrophages AOH changed the cell morphology of from round to star-shaped cells, with increased levels of CD83, CD86, CD11b,

Adsorption performance and mechanism of mycotoxin on montmorillonite modified by organosilicon grafting

Arabian Journal of Chemistry, 2021
Abstract A series of modified montmorillonites were prepared by acid modification method prior to the organosilicon grafting. Aflatoxin B1, zearalenone and deoxynivalenol (DON) were selected to evaluated the mycotoxin adsorption performance of modified montmorrillonites.

From Waste to Plant‐Based Protein: Impact of Solid‐State Fermentation on Functionality and Protein Extraction of Cassava Leaves

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Cassava leaves represent a significant waste stream in cassava cultivation, currently underutilized in both food and nonfood applications. This study investigates the use of solid‐state fermentation with Aspergillus oryzae, Lactobacillus plantarum, and Bacillus subtilis to modify the composition and functional ...

Strategies for estimating human exposure to mycotoxins via food [PDF]

, 2016
In this review, five strategies to estimate mycotoxin exposure of a (sub-) population via food, including data collection, are discussed with the aim to identify the added values and limitations of each strategy for risk assessment of these chemicals ...
