Perfluoroundecanoic acid induces DNA damage, reproductive and pathophysiological dysfunctions via oxidative stress in male Swiss mice.

Perfluoroundecanoic acid (PFUnA) is an eleven carbon-chain compound that belongs to the perfluoroalkyl carboxylic acid family. It has been detected in the human blood, effluents, and surface/ground waters, but its toxic effects to the DNA and reproductive system remain unclear. This study was aimed at exploring the toxicity of PFUnA on the hepatic DNA, organ-system and reproductive system in orally treated male Swiss mice.

The first-line antituberculosis drugs, and their fixed-dose combination induced abnormal sperm morphology and histological lesions in the testicular cells of male mice.

Rifampicin (RIF), Isoniazid (INH), Ethambutol (EMB), Pyrazinamide (PZA), and/or their fixed-dose combination (FDC) are extensively prescribed in the cure of Tuberculosis (TB) globally. In spite of the beneficial effect, these drugs are capable of inducing cellular toxicity. Existing information on the genotoxic effects of the first-line anti-TB drugs is limited and contentious.

Haematological Studies and Micronucleus Assay of Straw-Coloured Fruit Bats (Eidolon helvum).

The straw-coloured fruit bats (Eidolon helvum) are the most widely distributed megachiropteran species in Africa. Studies have shown that they migrate, and are likely exposed to environmental pollutants across population. This study was designed to investigate genotoxicity via the bone marrow micronucleus assay and haematological alterations of Eidolon helvum in the tropics.

Evaluation of long-term dermal exposure to soil contaminated with spent engine oil in male Wistar rats: An experimental approach.

Continuous occupational exposure to spent engine oil (SEO) poses physiological risks to humans, especially to automobile mechanics. This study investigated the physiological effects of SEO-contaminated soil in a male Wistar rat model. Animals were dermally exposed to soil contaminated with SEO for 120 consecutive days and compared with rats exposed to uncontaminated soil (negative control).

Titanium dioxide nanoparticles-induced cytogenotoxicity and alterations in haematological indices of (Burchell, 1822).

The application of titanium dioxide (TiO) nanoparticles (NPs) in the manufacturing of consumer products has increased tremendously and with the potential to induce deleterious effects on aquatic biota. There have been reports on metal oxide NP toxicity in aquatic organisms, however, information on cytotoxicity and genotoxicity of TiO NPs on the African catfish, , is scarce. In this study, we investigated the genotoxicity and haematotoxicity of TiO NPs in using the micronucleus (MN) assay and haematological analysis, respectively.

Alteration of sperm parameters and reproductive hormones in Swiss mice via oxidative stress after co-exposure to titanium dioxide and zinc oxide nanoparticles.

In this study, Swiss male mice were intraperitoneally administered with titanium dioxide (TiO ) and zinc oxide (ZnO) nanoparticles (NPs) and their mixture (1:1) at doses between 9.38 and 75 mg/kg for 5 weeks to evaluate reproductive toxicity. Both NPs and their mixture significantly (p < .
