A mathematical model of DNA degradation: Possible role of magnetic nanoparticles [PDF]
A mathematical model of genome degradation is proposed that takes into account a variable rate of mutation and increasing number of cells in a developing human organism. The model explains known properties of cancer development, in particular, a synergism between different mutagens and an increased probability of cancer in the early years of life.

A comparison of the effects of physical and chemical mutagens in sesame (Sesamum indicum L.)
Three sesame genotypes (Rama, SI 1666 and IC 21706) were treated with physical (γ-rays: 200 Gy, 400 Gy or 600 Gy) or chemical (ethyl methane sulphonate, EMS: 0.5%, 1.0%, 1.5% or 2.0%) mutagens and their mutagenic effectiveness and efficiency were ...

The Use of the Ames Test as a Tool for Addressing Problem-Based Learning in the Microbiology Lab
Our environment is full of potential carcinogens such as UV light, industrial pollutants, pesticides, and food additives, among others. It is estimated that 90% of all carcinogens are also mutagens.

A series of benzimidazolium chlorides and their 2‐mercapto were successfully synthesized and characterized. Cytotoxic activity assays revealed that certain synthesized compounds exhibited efficacy against cancer cell lines. To investigate the possible mechanism underlying their cytotoxic effects, the binding interactions of the three most active ...

DNA Copy Number Variations as Markers of Mutagenic Impact [PDF]
DNA copy number variation (CNV) occurs due to deletion or duplication of DNA segments resulting in a different number of copies of a specific DNA-stretch on homologous chromosomes.

Micronucleus induction by 915 MHz Radiofrequency Radiation in Vicia faba root tips [PDF]
The mutagenic effect of radiofrequency electromagnetic field (RF-EMF) is evaluated by the micronucleus (MN) test in secondary roots of Vicia faba seedlings. Root exposures were carried out with 915 MHz continuous wave (CW) radiation for 72h, at power densities of 25, 38, 50 W/m$^2$.

ABSTRACT Introduction Gastric cancer (GC) remains among the top five global health problems. Therefore, comprehending the tumor energetic behavior is critical to understanding its progression. This study aimed to investigate mitochondrial DNA (mtDNA) alterations in GC cancer cell lines in an animal model.

Dynamics and bifurcations in a simple quasispecies model of tumorigenesis [PDF]
Cancer is a complex disease and thus is complicated to model. However, simple models that describe the main processes involved in tumoral dynamics, e.g., competition and mutation, can give us clues about cancer behaviour, at least qualitatively, also allowing us to make predictions.
