Summary: The study found that none of the ten fried meat-based food extracts induced gene mutations in Salmonella typhimurium TA98, but five of them induced chromosomal aberrations in TK6 cells after 24 hours without metabolic activation. Further studies are needed to validate the biological relevance of these in vitro findings.

Summary: Herbs used in traditional medicine can have both beneficial and harmful effects on human health. A study conducted in Belgium investigated the cytotoxicity and genotoxicity of Aristolochia and Magnolia extracts on human kidney cells. The study also evaluated the mutagenicity of these extracts using the Ames test. The results showed that the Aristolochia-Magnolia combination was more genotoxic and cytotoxic to human kidney cells, and it exhibited mutagenic effects in the presence of a microsomial liver fraction.

Summary: Mycotoxins, which are produced by fungi, pose a threat to public health due to their potential carcinogenic, mutagenic, and teratogenic effects. This study developed a comprehensive database of 4360 mycotoxins classified into 170 categories. The use of QSAR models allowed for accurate and reliable prediction of mutagenicity, genotoxicity, and carcinogenicity, meeting regulatory criteria. The integrated web server provides a valuable tool for exploring the mycotoxin database and predicting toxicity.

Summary: This study evaluated the cytotoxic and mutagenic effects of morphine alone and in combination with doxorubicin. Morphine showed cytotoxic effects on neuroblastoma cells and reduced the cytotoxic effects of doxorubicin. Morphine did not induce mutations and decreased the mutagenic effects induced by doxorubicin in certain strains.

Summary: Consumer use of CBD for personal wellness has gained public interest, but there is limited safety data on CBD's genotoxic potential. To address this data gap, a study investigated the genotoxic potential of a pure CBD isolate using three genotoxicity assays. The results of these assays indicate that CBD is unlikely to pose a genotoxic hazard.

Summary: This study evaluated the mutagenicity and genotoxicity of industrially processed meat products sold in popular supermarkets in Algeria. The results showed that all extracts analyzed did not induce mutagenic activity, but one extract did cause a significant increase in the number of micronucleated cells. This highlights the importance of genetic damage detection in reducing exposure to harmful contaminants and the need for further research on genotoxic effects of processed meat globally.

Summary: This study partitioned data from multiple databases using the weight-of-evidence method and established nine sub-models and three fusion models based on different experimental combinations. These models, built with random forest, support vector machine, and back propagation algorithms, showed high prediction accuracy rates and can serve as an early warning system for mutagenicity of compounds.

Summary: Mycotoxins and their metabolites are a diverse group of compounds with varying structures and biological properties. Given the large number and diversity of these molecules, it is impractical to individually assess their toxicity. To address this, new approach methodologies (NAMs) such as quantitative structure-activity relationship (QSAR) models can be utilized for hazard evaluation. In this study, a comprehensive list of 904 mycotoxins and metabolites was compiled, and the best QSAR tools for predicting mutagenicity and carcinogenicity were determined using known mycotoxins. The identified 95 mycotoxins with both mutagenic and carcinogenic properties should be prioritized for further evaluation.

Summary: The hydrolysis of organic chemicals can impact the fate and behavior of environmental contaminants, leading to the importance of evaluating substance stability in water. Information on hydrolysis is required for the registration of organic compounds in Europe, and computational models may offer a cost-effective alternative. The CORAL software was used to build QSPRs for modeling hydrolysis, with consideration of ring nature and atom pair proportions.

Summary: Carcinogenicity testing is important for human health and regulatory compliance. However, traditional rodent studies are time-consuming and expensive, so alternative methods are needed. This study proposes the use of the Monte Carlo technique and CORAL software to construct models for reliable carcinogenicity assessments using available experimental data. The presence of double bonds between carbon atoms and double bonds of oxygen atoms indicates the carcinogenic potential of a compound.

Summary: 3-MCPD is a chiral molecule that exists naturally as a mixture of (R)- and (S)-enantiomers. It was studied as a male antifertility drug in the 1970s, but research was discontinued due to observed side effects. However, it was later found to be a widespread contaminant in processed foods. Toxicological studies have shown that 3-MCPD primarily affects the kidney and reproductive system, followed by the neurological and immune systems. Further research is needed to understand the absorption, metabolism, and long-term toxicity of 3-MCPD esters for improved risk assessment.

Summary: Quantitative structure-property/activity relationships (QSPRs/QSARs) are important tools in modern theoretical and computational chemistry. The self-consistent model system is used to build and assess the reliability of a group of QSPR/QSAR models. In this study, models predicting pesticide toxicity towards Daphnia magna were compared for different training and test subsets. The results were used to formulate a self-consistent model system, which improved the predictive potential of the models. The suggested models showed high predictive potential, with an average determination coefficient of 0.841 and dispersion of 0.033 for the validation sets. The best model achieved an average determination coefficient of 0.89 for the external validation sets.

Summary: Phylogenetic analysis studies the evolution of species based on their biological characteristics and is often represented as phylogenetic trees. The neighbor-joining (NJ) algorithm is a widely used method for reconstructing phylogenetic trees based on evolutionary distances. However, the NJ algorithm can only produce bifurcating branches and does not consider multifurcating branches. To address this limitation, we have developed a new variant of the NJ algorithm called multifurcating neighbor-joining (MFNJ) algorithm, which can produce phylogenetic trees with multifurcating branches. The MFNJ algorithm ensures reproducibility and unbiased results in experimental studies.
