Aloe vera in Food Preservation: Harnessing Bioactive Constituents for Clean‐Label Innovation and Safety Assurance

Food Safety and Health, EarlyView.
Aloe vera‐derived biopolymers and nanoformulations enhance antimicrobial, antioxidant, and barrier functions in clean‐label edible coatings and films, whereas safety‐critical anthraquinone thresholds and regulatory constraints shape their translational potential.

CDK4/6 inhibitor-induced bone marrow micronuclei might be caused by cell cycle arrest during erythropoiesis

Genes and Environment
Background A micronucleus test is generally used to evaluate the genotoxic potential of chemicals. Exaggerated erythropoiesis, as occurs following bleeding, may induce an unexpected increase in micronucleus frequency.

Hypoxia Induces a Mitotic Survival Advantage After Radiotherapy in Head and Neck Cancer Cells

International Journal of Cancer, EarlyView.
Hypoxic tumor environments significantly limit radiotherapy effectiveness against cancer, particularly in head and neck squamous cell carcinoma (HNSCC). Here, the authors tracked hypoxic and post‐hypoxic cells using a hypoxia‐fate mapping system in human papillomavirus (HPV)‐positive and HPV‐negative HNSCC models.

Formation of viable cell fragments by treatment with colchicine [PDF]

, 1976
Time-lapse cinematography of human fibroblasts revealed that mitotic cells separated into numerous cell fragments containing varying amounts of chromatin and cytoplasm when treated with colchicine.

Lymphocyte Micronucleus Formation Is Driven by Inflammation‐Induced Oxidative DNA Damage in Oesophageal Cancer Development

International Journal of Cancer, EarlyView.
Chromosomal instability is a hallmark of cancer, but minimally invasive ways to detect systemic DNA damage and cancer risk remain limited. Here, using patient blood samples, the authors investigated lymphocyte micronuclei (MN) frequency as a potential marker of DNA damage across the progression from gastroesophageal reflux disease to Barrett's ...

Evaluation of the genotoxic potential of Austroplenckia populnea (Reiss) Lundell chloroform fraction from barkwood extract in rodent cells in vivo Avaliação do potencial genotóxico da fração clorofórmica de cascas do caule de Austroplenckia populnea em células de roedores in vivo

Brazilian Journal of Biology, 2009
The genotoxic effect of the Austroplenckia populnea chloroform fraction from barkwood extract was tested in vivo on peripheral blood cells of Swiss mice with the comet assay (SCGE), and the clastogenic effect was investigated on peripheral blood cells of

EURL ECVAM strategy to avoid and reduce animal use in genotoxicity testing [PDF]

, 2013
The assessment of genotoxicity represents an important component of the safety assessment of all types of substances. Although several in vitro tests are available at different stages of development and acceptance, they cannot at present be considered to

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

Journal of Applied Toxicology, EarlyView.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...
