Environmental pollution by pesticide residues is a major environmental concern due to the extensive use of these substances in agriculture. The insecticide beta-cyfluthrin is a synthetic pyrethroid widely used in agricultural and other domestic activities. The aim of the present study was to assess the genotoxic effects of a sublethal exposure of the fish Bryconamericus iheringii (Characidae) to a commercial formulation of beta-cyfluthrin using the comet assay. Fish were exposed to sublethal concentrations (4.2 and 5.6 microg/L) of beta-cyfluthrin under static conditions during 24- and 48-h exposure periods. Fish in tap water were used as negative controls. Results obtained by the comet assay revealed genotoxic effects of the pyrethroid in the higher concentration and at the longer exposure period. The mean DNA damage index of fish exposed to 5.6 microg/L beta-cyfluthrin for 48 h was significantly higher (145.9 +/- 51.8) than in the control group (69.3 +/- 39.5). These findings indicate that native fish species might be at risk for genotoxic damage in waters contaminated with beta-cyfluthrin.

A bio-fabrication approach is a novel way to develop chitosan-stabilized magnesium oxide nanomaterials (cMgO-NMs). The process involves utilizing polymeric chitosan as the reducing and stabilizing agent. The characteristics of the developed cMgO-NMs were determined using various spectroscopical techniques.

Bisphenol A (BPA), a common endocrine disrupting chemical (EDC), has shown detrimental effects on sperm quality and function in experimental models. However, epidemiological evidence is inconsistent and also there exists a notable lack of data on its analogues, such as bisphenol F (BPF) and bisphenol S (BPS). To investigate the relationships between BPA, BPF and BPS exposures and sperm DNA damage, we conducted a cross-sectional study recruiting 474 Chinese men from an infertility clinic in Wuhan, China.

Objective: This study investigates the mechanism underlying sorafenib resistance in hepatocellular carcinoma cells (HCC), focusing on DNA damage repair (DDR) pathways to develop targeted therapeutic strategies.
Methods: Bioinformatics analysis was used to screen genes associated with sorafenib resistance, which was further demonstrated by western blotting. Cell proliferation was determined using the EdU assay.

Sulfoxaflor (SFX) is an insecticide that is commonly used for the control of sap-feeding insects. Since SFX is extensively applied globally, it has been implicated in the substantial induction of environmental toxicity. Therefore, in this study, Allium cepa roots have been employed to elucidate the potential cytogenotoxic effects of SFX in non-target cells by examination of mitotic index (MI), chromosomal aberrations (CAs), and DNA damage.

Introduction: Torque Teno Virus (TTV), an "orphan" virus with unclear pathology, has been associated with various diseases and immune dysfunctions. This study investigates the link between TTV viremia and clinical markers in patients with severe to very severe COPD undergoing respiratory rehabilitation.
Methods: We analyzed 102 elderly COPD patients, stratified by TTV viremia levels (< or ≥ 4 log10 copies/mL).
