Giemsa versus acridine orange staining in the fish micronucleus assay and validation for use in water quality monitoring [PDF]

, 2011
This study concerns a comparative analysis of the acridineorange and Giemsastaining procedures for the fish erythrocyte micronucleusassay. The goal was to optimize the assay in the context of field watermonitoring. Fish (Carassius carassius) were exposed

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

Journal 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.

MICRONUCLEI: A PROGNOSTIC TOOL

Journal of Evolution of Medical and Dental Sciences, 2014
Squamous cell carcinoma is one the most common oral mucosal malignant tumor, diagnosis of oral squamous cell carcinoma rarely presents difficulty, it is the cancer staging and histo pathological grading that are more important for prognosis, micronuclei are good prognostic indicator. Micronuclei screening can be done easily by exfoliative cytology, one

Bisphenol A Induces DNA Damage and Differential Cytotoxicity in Thyroid Cells: High‐Dose Effects Challenge Regulatory Thresholds

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), a ubiquitous environmental endocrine disruptor, has been implicated in carcinogenesis; however, its effects on thyroid cells remain unclear. This study investigated BPA‐induced cytotoxicity and genotoxicity in thyroid cell lines, including normal follicular (Nthy‐ori 3‐1), papillary carcinoma (TPC‐1 and BCPAP) and anaplastic

Evaluation of the cytotoxic and genotoxic potential of Khat (Catha edulis Forsk) extracts on human T lymphoblastoid cell line

, 2004
This paper reports on an investigation of the cytotoxic and genotoxic potential of khat extract using a human T lymphoblastoid cell line (CEM). Exponentially growing CEM cells were cultured for 12 h in the presence of khat extract (0-2000 μg ml-1 ...

Evaluation of DNA/Chromosome Integrity and Cell Death in Human Metabolically Noncompetent and Competent Cells Exposed to N′‐(3,5‐Difluorobenzylidene)Pyridine‐4‐Carbohydrazide

Journal of Applied Toxicology, EarlyView.
ABSTRACT The N‐acylhydrazone scaffold is recognized as a privileged structure for the design of bioactive substances with increasing applications in medicinal chemistry research. Ensuring the safety of newly developed molecules is a critical step for both human health and environmental protection. Accordingly, this study aimed to evaluate the cytotoxic

Micronuclei in Kif18a mutant mice form stable micronuclear envelopes and do not promote tumorigenesis.

, 2021
Micronuclei, whole or fragmented chromosomes spatially separated from the main nucleus, are associated with genomic instability and have been identified as drivers of tumorigenesis.

Cellular Responses to Tartrazine and Sulfanilic Acid Exposure in BEAS‐2B Cells: Viability, Apoptosis, and DNA Damage

Journal of Applied Toxicology, EarlyView.
ABSTRACT Tartrazine is a synthetic azo dye widely used in food, pharmaceutical, and cosmetic products, resulting in extensive human exposure, while its toxicity and that of its primary metabolite, sulfanilic acid, remain controversial. Considering the reported association of tartrazine with hypersensitivity and allergic‐like reactions, human bronchial ...

Validation of the micronucleus-centromere assay for biological dosimetry

Genetics and Molecular Biology, 2000
The micronucleus assay is frequently used for purposes of biological dosimetry. Due to high interindividual variability in the spontaneous frequency of micronuclei, its sensitivity in the low dose region is poor.
