Determination of Aflatoxins and Selected Heavy Metals in Rice Varieties Cultivated in Fogera, Amhara Region, Ethiopia

Food Chemistry International, EarlyView.
ABSTRACT Rice (Oryza sativa L.) is a vital staple crop for nearly half the world's population. This study investigates the levels of aflatoxins (AFB1, AFB2, AFG1, and AFG2) and selected heavy metals (Cd, Pb, and Cr) and essential elements (Mn, Fe, Mg, Cu, and Zn) in rice varieties cultivated in Fogera, Amhara Region, Ethiopia.

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

Journal 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,

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Among Children Exposed to Environmental Mutagens: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

Arsenite exposure induces premature senescence and senescence-associated secretory phenotype (SASP) in human hepatocyte-derived cell line Huh-7

Environmental Health and Preventive Medicine
Background: Chronic arsenite exposure has been known to induce cancer in various organs; however, the underlying mechanisms remain elusive. The characteristic feature of carcinogenesis due to arsenic exposure is that the disease develops after a ...

m6A Demethylase FTO Regulates Dopaminergic Neurotransmission Deficits Caused by Arsenite

Toxicological Sciences, 2018
Arsenite exposure is known to increase the risk of neurological disorders via alteration of dopamine content, but the detailed molecular mechanisms remain largely unknown. In this study, using both dopaminergic neurons of the PC-12 cell line and C57BL/6J

Anaerobic Arsenite Oxidation by an Autotrophic Arsenite-Oxidizing Bacterium from an Arsenic-Contaminated Paddy Soil

, 2015
Microbe-mediated arsenic (As) redox reactions play an important role in the biogeochemical cycling of As. Reduction of arsenate [As­(V)] generally leads to As mobilization in paddy soils and increased As availability to rice plants, whereas oxidation of ...

Modulation of the Stress Granule Component Carhsp1 Mitigates Disease‐Associated Deficits in Spinocerebellar Ataxia Type 3 Mouse Models

Movement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a polyglutamine (polyQ) neurogenerative disorder that results from CAG trinucleotide repeat expansions in the ATXN3 gene, leading to toxic protein aggregate formation and cellular pathway dysfunction.
