¿Influye la ozonoterapia sobre la médula ósea de ratones tratados?

Revista Cubana de Investigaciones Biomédicas
Se realizó el estudio de la actividad genotóxica del oleozón, mediante el ensayo de micronúcleos en médula ósea, en ratones de la línea Cenp:NMRI de uno y otro sexos; este ensayo constituye una determinación indirecta de la inducción de aberraciones ...

The Potential of Walnut Seeds (Canarium indicum L.) in Repairing The Genotoxicity Effect of Mercury on Mice Erythrocytes

Borneo Journal of Pharmacy, 2019
Hydrargyrum (familiar as mercury) is a persistent transition metal element. They are known as bio-accumulative properties that are dangerous to the environment and has serious damaging effects on biota, including genetic changes or mutagenesis. Moreover,

A Unified Deep Learning Framework for Instance Segmentation Across Diverse Cytological Stains

Cytopathology, EarlyView.
Transformer‐based unified cytology segmentation across Papanicolaou, Feulgen and AgNOR achieves stain‐invariant performance. Mask2Former maximises boundary precision (AP75) on the combined dataset, enabling one model to replace multiple stain‐specific deployments without accuracy loss while simplifying clinical integration.

Increased Genetic Instability in Exfoliated Oral Cells in Patients With Epidermolysis Bullosa

Oral Diseases, EarlyView.
ABSTRACT Objective To analyze the nuclear abnormalities of cytotoxicity—karyorrhexis (KR), karyolysis (KL), and pyknosis (PN)—and genotoxicity—micronucleus (MN) in exfoliated cells from different sites of the oral mucosa in patients with Epidermolysis Bullosa (EB) and a control group.

Prolonged exposure to artificial light and carcinogenesis: A systematic review of oncostatic mechanisms associated with melatonin pathways

Photochemistry and Photobiology, EarlyView.
Exposure to artificial light at night (ALAN), particularly at blue wavelengths, disrupts circadian rhythms by suppressing melatonin, thereby increasing cancer susceptibility. This systematic review consolidates evidence linking prolonged ALAN exposure to an elevated risk of breast and prostate tumors.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

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

International Journal of Cancer, Volume 159, Issue 4, Page 1042-1055, 15 August 2026.
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.

Quantitative Control of Transposable Elements: From Genome Plasticity to Immune Regulatory Circuits

Cell Biochemistry and Function, Volume 44, Issue 7, July 2026.
ABSTRACT Transposable elements (TEs) constitute nearly half of the human genome and are increasingly recognized as context‐dependent regulators of genome function rather than passive repetitive DNA. This Review synthesizes classical and recent evidence on TE biology, including TE classification, mechanisms of mobilization, host restriction pathways ...
