Modulation of gene expression by thymoquinone conjugated zinc oxide nanoparticles arrested cell cycle, DNA damage and increased apoptosis in triple negative breast cancer cell line MDA-MB-231.

Nanomedicines include the area of science that combines the drugs or diagnostic molecules using nanotechnology approach to improve its ability to target specific cells or tissues. Zinc oxide (ZnO) nanoparticles are known for its non-toxicity, biocompatibility and biosafety. Thymoquinone (TQ) is used in the present study from the seeds of (Black cumin seed).

Seed and bark extracts of Acacia catechu protects liver from acetaminophen induced hepatotoxicity by modulating oxidative stress, antioxidant enzymes and liver function enzymes in Wistar rat model.

In this study we investigated the hepatoprotective effects and possible mechanism of Acacia catechu in acetaminophen (APAP) induced hepatotoxicity using female Wistar rat model. Hepatotoxicity was induced by oral administration of acetaminophen (750 mg/kg body weight) for 24 h. The seed (400 mg/kg body weight) and bark (400 mg/kg body weight) extract's treated groups exhibited hepatoprotective effects and was compared with well-known clinical anti-dote N-acetylcysteine (NAC).

Fumigant toxicity of plant essential oils against Camptomyia corticalis (Diptera: Cecidomyiidae).

The toxicity of 98 plant essential oils against third instars of cecidomyiid gall midge Camptomyia corticalis (Loew) (Diptera: Cecidomyiidae) was examined using a vapor-phase mortality bioassay. Results were compared with that of a conventional insecticide dichlorvos. Based on 24-h LC50 values, all essential oils were less toxic than dichlorvos (LC50, 0.
