His+ reversions Caused in Salmonella typhimurium by different types of ionizing radiation [PDF]

open access: yes, 1988
The yield of his+ reversions in the Ames Salmonella tester strain TA2638 has been determined for 60Co γ rays, 140 kV X rays, 5.4 keV characteristic X rays, 2.2 MeV protons, 3.1 MeV α particles, and 18 MeV/U Fe ions.

DNA Replication Errors Drive Genome‐Wide Small Inverted Triplication Dynamics

open access: yesAdvanced Science, EarlyView.
This study provides insight into the dynamic equilibrium mechanism of a novel structural variant, small inverted triplication (SIT), which is generated by misalignment of the 3’ flap generated under DNA replication stress with palindromic sequence. Alternatively, the end sequence may fold back on itself to form an inverted fragment.

An open source multistep model to predict mutagenicity from statistical analysis and relevant structural alerts

open access: yesChemistry Central Journal, 2010
Background Mutagenicity is the capability of a substance to cause genetic mutations. This property is of high public concern because it has a close relationship with carcinogenicity and potentially with reproductive toxicity. Experimentally, mutagenicity

Pharmacological evaluation of Adenostemma lavenia acetone extract in Swiss Albino mice: Analgesic, anti‐inflammatory, and thrombolytic insights from in vivo, in vitro, density functional theory, and molecular docking studies

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Adenostemma lavenia, a traditionally used medicinal plant, has been employed to manage pain, inflammation, and circulatory issues. This study investigates the analgesic, anti‐inflammatory, and thrombolytic potentials of the acetone extract of A. lavenia leaves (AEAL) using in vivo, in vitro, and in silico methods.

The genoprotective activity of resveratrol on permethrin-induced genotoxic damage in cultured human lymphocytes

open access: yesBrazilian Archives of Biology and Technology, 2013
The aim of this work was to investigate the genetic effects of resveratrol (RSV) at concentrations of 10, 15, 25, 40, 75 and 100 µM and its activities on the genotoxicity induced by the permethrin (PM) (200 µM).

Spatial Cell Death and Oxidative Stress Dynamics in Gas Plasma‐Treated Tumor Tissues

open access: yesAdvanced NanoBiomed Research, EarlyView.
Schematic representation of the four experimental models to study tissue penetration and oxidation. Four tissue models were used. Human pancreatic cancer cells were grown on the chorioallantois membrane of chicken embryos and gas plasma‐treated in ovo, murine colorectal tumor tissue was gas plasma‐exposed ex vivo, murine squamous cell carcinoma cells ...

Potential hazard of simultaneous occurrence of aflatoxin B-1 and ochratoxin A

open access: yesVeterinární Medicína, 2001
Contents of aflatoxin B1 (AFB1) and ochratoxin A (OA) in the samples of wheat and barley were detected by RIA method. Average contents of AFB1 in the samples of wheat and barley were 2.4 µg/kg and 2.2 µg/kg, respectively.

Mutagenic and/or carcinogenic compounds in meat and meat products: Heterocyclic aromatic amines perspective

open access: yesТеория и практика переработки мяса, 2022
Meat and meat products, which have a very important place in terms of nutrition, can endanger human health if they are not properly prepared and preserved. Meat and meat products except for products such as sushi, which are deliberately consumed raw, are
