Rosmarinus officinalis L. ameliorates titanium dioxide nanoparticles and induced some toxic effects in rats' blood.

Titanium dioxide nanoparticles (TiO NPs) have been widely used as a white pigment in food and drugs. The most important route of human exposure to TiO is through food and drug products containing TiO additives. This study investigates the efficacy of an oral traditional use of rosemary extract in ameliorating some toxic effects induced on blood of TiO NP-intoxicated rats.

Assessment of human sperm DNA integrity using two cytochemical tests: Acridine orange test and toluidine blue assay.

Primary infertility affects approximately 15% of couples, with male factor infertility accounting for 50% of cases. Semen samples from 41 patients with asthenoteratospermia and 28 men with proven fertility were analysed according to World Health Organization guidelines. Abnormal sperm chromatin structure was assessed by toluidine blue assay (TBA), and DNA denaturation (DD) was detected by the acridine orange test (AOT).

Circadian variation of cytotoxicity and genotoxicity induced by an immunosuppressive agent "Mycophenolate Mofetil" in rats.

Immunosuppressive drugs such as Mycophenolate Mofetil (MMF) are used to suppress the immune system activity in transplant patients and reduce the risk of organ rejection. The present study investigates whether the potential cytotoxicity and genotoxicity varied according to MMF dosing-time in Wistar Rat. A potentially toxic MMF dose (300 mg/kg) was acutely administered by the i.

The effect of titanium dioxide nanoparticles on neuroinflammation response in rat brain.

Titanium dioxide nanoparticles (TiO NPs) are widely used for their whiteness and opacity in several applications such as food colorants, drug additives, biomedical ceramic, and implanted biomaterials. Research on the neurobiological response to orally administered TiO NPs is still limited. In our study, we investigate the effects of anatase TiO NPs on the brain of Wistar rats after oral intake.
