The role of ferroptosis in environmental pollution-induced male reproductive system toxicity.

This article provides a comprehensive review of the toxic effects of environmental pollution on the male reproductive system, with a particular emphasis on ferroptosis, a form of programmed cell death. Research has shown that environmental pollutants, such as heavy metals, pesticide residues, and plastic additives, can disrupt oxidative stress, increasing the production of reactive oxygen species (ROS) in germ cells. This disruption damages cellular lipids, proteins, and DNA, culminating in cell dysfunction or death.

Protective Mechanisms of Various Active Substances on Cell DNA Damage and Apoptosis Induced by Deoxynivalenol.

Deoxynivalenol (DON) is a secondary metabolite of fungi that is harmful to humans and animals. This study examined the protective effects of natural substances, including resveratrol, quercetin, vitamin E, vitamin C, and microbe-derived antioxidants (MA), on both human gastric mucosal cells (GES-1) and pig small intestinal epithelial cells (IPEC-1) when induced by DON. Cells were incubated with active substances for 3 h and then exposed to DON for 24 h.

DON induced DNA damage triggers absence of p53-mediated G2 arrest and apoptosis in IPEC-1 cells.

Deoxynivalenol (DON) stands among the prevalent mycotoxins, and usually contaminates cereal foods and animal feed, leading to human and animal clinical poisoning symptoms such as abdominal pain, diarrhea, and vomiting. To date, the mechanism of toxicity of DON in different mammalian cells is not fully elucidated. In this study, we explored the detrimental impacts of DON on porcine intestinal epithelial cells (IPEC-1), serving as a representative model for porcine intestinal epithelial cells.

DON entry into the nucleus induces DNA damage, apoptosis and cycle arrest in GES-1 cells.

Deoxynivalenol (DON) is a mycotoxin produced by the genus Fusarium and belongs to the trichothecenes group B compound. At present, the mechanism of DON toxicity to mammalian cells is not fully understood. Since the stomach is the first physiological barrier against food contaminants, it is also the first target of exposure to toxins.

Overview-gold nanoparticles-based sensitive nanosensors in mycotoxins detection.

Food-borne mycotoxins is one of the food safety concerns in the world. At present, nanosensors are widely used in the detection and analysis of mycotoxins due to their high specificity and sensitivity. In nanosensor-based mycotoxindetections, the sensitivity is mainly improved from two aspects.

The toxicity mechanisms of DON to humans and animals and potential biological treatment strategies.

Deoxynivalenol, also known as vomitotoxin, is produced by , belonging to the group B of the trichothecene family. DON is widely polluted, mainly polluting cereal crops such as wheat, barley, oats, corn and related cereal products, which are closely related to lives of people and animals. At present, there have been articles summarizing DON induced toxicity, biological detoxification and the protective effect of natural products, but there is no systematic summary of this information.

Pre-exposure to Streptococcus suis improved survival of influenza virus co-infection in mice.

The synergism of the influenza virus and respiratory tract pathogens is known to exacerbate diseases in both humans and animals. The mechanism of the co-infection of associated respiratory tract pathogens is explored in this study. Co-infection has a directional effect when influenza virus or other pathogens occur in a different order.

Ultrasensitive and green electrochemical immunosensor for mycotoxin ochratoxin A based on phage displayed mimotope peptide.

Here, we demonstrated a new approach for development of an ultrasensitive and green electrochemical immunosensor for Ochratoxin A (OTA). Phage displayed mimotope peptide of OTA was used as mimics of conventional competing antigen, which is chemical synthesized with toxic mycotoxins OTA as raw material, in a competitive sensing platform. The working electrode was modified by polyethylene glycol (PEG) for the purpose of immobilizing antibody effectively.
