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.

Canine Urothelial DNA Mutations Are Not Associated With Total Trihalomethanes Concentrations in Municipal Drinking Water

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Contaminants in municipal drinking water, specifically total trihalomethanes (TTHMs), are mutagenic. Exposures to TTHMs have been associated with urothelial carcinoma (UC) in both people and dogs. Mutations in the BRAF gene and other genomic copy number aberrations detected in voided urothelial cells with commercial CADET BRAF and BRAF‐PLUS ...

Cellular Effects of Naringin in Prevention of Genotoxicity Caused by Mifepristone on Human Blood Lymphocytes

Journal of Mazandaran University of Medical Sciences, 2018
Background and purpose: Mifepristone is an oral synthetic steroid with antiglucocorticoid and antiprogesterone activities. Therefore, it could be dangerous during pregnancy since it causes cytogenetic damage and, consequently, abortion.

The bromodomain-containing protein Ibd1 links multiple chromatin related protein complexes to highly expressed genes in Tetrahymena thermophila

, 2018
Background: The chromatin remodelers of the SWI/SNF family are critical transcriptional regulators. Recognition of lysine acetylation through a bromodomain (BRD) component is key to SWI/SNF function; in most eukaryotes, this function is attributed to ...

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 ...

Progeny of Germ Line Knockouts of \u3cem\u3eASI2\u3c/em\u3e, a Gene Encoding a Putative Signal Transduction Receptor in \u3cem\u3eTetrahymena Thermophila\u3c/em\u3e, Fail to Make the Transition from Sexual Reproduction to Vegetative Growth [PDF]

, 2006
The ciliated protozoan Tetrahymena has two nuclei: a germ line micronucleus and a somatic macronucleus. The transcriptionally active macronucleus has about 50 copies of each chromosome.

The effect of HIV and antiretroviral therapy on chromosomal radiosensitivity [PDF]

, 2015
Introduction: Antiretroviral Treatment (ART) has led to an improvement in survival of HIV infected individuals. Some of them will develop cancer during the course of their infection and will require radiation therapy.

Curcumin Nanoformulations for Dermatological Applications: From Nutraceuticals to Nanocarriers

Food Frontiers, Volume 7, Issue 3, May 2026.
Nanotechnology‐based delivery platforms enhance the cutaneous administration of curcumin. Loading free curcumin into polymeric micelles, metal‐based nanoparticles, nanogels/hydrogels, liposomes, polymeric nanoparticles, or nanoemulsions/nanocrystals helps address its low solubility, poor stability and limited skin permeation. As a result, these systems

Phenanthrene and nitrite effects on juvenile sea bass, Dicentrarchus labrax, using hepatic biotransformation enzymes, biliary fluorescence, and micronuclei as biomarkers

Ciencias Marinas, 2009
Aquatic organisms may absorb organic compounds mainly from water and by ingestion of contaminated food. The toxicity of such compounds may be intensified by the presence of certain inorganic compounds such as nitrite (NO2–).
