Micronuclei and Other Nuclear Abnormalities in Patella Limpet as Biomarkers of Cytogenotoxicity in Recreational Port Waters

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

Assessment of the genetic risks of a metallic alloy used in medical implants

open access: yesGenetics and Molecular Biology, 2011
The use of artificial implants provides a palliative or permanent solution for individuals who have lost some bodily function through disease, an accident or natural wear. This functional loss can be compensated for by the use of medical devices produced

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Comparison of nuclear abnormalities in Astyanax bifasciatus Cuvier, 1819 (Teleostei: Characidae) of two sections of rivers from the middle Iguaçu

open access: yesActa Scientiarum: Biological Sciences, 2018
Most changes in water bodies are result of human activities that have the potential to undermine the environmental integrity of aquatic ecosystems. Changes in genetic material can be evidenced by the frequency of nuclear abnormalities in fish blood cells,

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Trace Levels of Triclosan May Affect Root Growth and Morphology in Cultivated Plants

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) is a micropollutant frequently detected in biosolids applied to agricultural soils. In soil solution—where it is potentially bioavailable to roots—it occurs at residual concentrations (ng L−1). Nevertheless, the ecotoxicological implications of TCS exposure in agricultural crops at these concentrations are still not fully ...

Chromosomal and immune dysregulation underlying granular mitosis in glioblastoma

open access: yesBrain Pathology, EarlyView.
Granular mitosis (GM) morphology is linked to PI3K/PTEN pathway alterations, chromosomal disorganization, and impaired innate immunity. Cells exhibiting GM morphology are associated with localized immune responses within their immediate spatial microenvironment.

Splicing Factor Mutations in Clonal Hematopoiesis and Progression to Myeloid Neoplasms

open access: yesCancer Science, EarlyView.
Splicing factor (SF)‐mutant CH is characterized by relatively late emergence and accelerated clonal expansion in older individuals. This review summarizes its clonal dynamics, disease‐associated consequences of SF mutations in myeloid neoplasms, and candidate mechanisms that may contribute to age‐dependent selection.

Investigation of Toxic Effects of the Glyphosate on Allium cepa

open access: yesJournal of Agricultural Sciences, 2011
In the present study, toxic effects of glyphosate on Allium cepa L. (Amaryllidaceae) cells were investigated. For this aim, we used the germination percentage, root length, seedling weight, malondialdehyde (MDA) level, frequency of micronucleus (MN ...

Micronucleus Frequency Test in Epithelial Cells Desquamated From the Oral Mucosa of Patients With Fanconi Anemia

open access: yesJournal of Oral Pathology &Medicine, EarlyView.
ABSTRACT Background Fanconi anemia (FA) is a rare genetic disorder predisposing patients to oral squamous cell carcinoma (OSCC). Hematopoietic stem cell transplantation (HSCT) corrects bone marrow failure but may increase the risk of malignancies. Exfoliative cytology and the micronucleus (MN) test provide noninvasive assessment of genomic instability.
