Larvicidal activity of methanolic and aqueous extracts of Lavandula dentata and Nerium oleander flowers against the vector of avian malaria Culiseta longiareolata.

In light of the adverse effects of chemical insecticides on the environment and human health, as well as the development of mosquito resistance to them, this study explores the potential of methanol and aqueous flower extracts from Lavandula dentata and Nerium oleander as bioinsecticides against Culiseta longiareolata mosquitoes. Additionally, it aims to assess the impact of these extracts on enzymatic biomarkers and biochemical composition of fourth instar larvae of Culiseta longiareolata.Qualitative analysis revealed the presence of flavonoids, terpenes, gallic and catechic tannins in both plant extracts.

Screening of the phytochemical constituents of Teucrium polium extract and evaluation of their prophylactic role against the oxidative damage and cytotoxicity of Aflatoxin B in rats.

Aflatoxin B (AFB) is common carcinogen causing acute and chronic hepatocyte injuries. This study aimed to determine the bioactive components of Teucrium polium methanolic extract (TPE) and to evaluate their protective role against AFB-induced oxidative damage, cytotoxicity, and genotoxicity in rats. Six groups of male albino rats were treated orally for 4 weeks including the control group, the ِAFB-treated group (80 μg/kg b.

Costus speciosus extract protects against the oxidative damage of zearalenone via modulation of inflammatory cytokines, Nrf2 and iNOS gene expression in rats.

Zearalenone (ZEN) is a non-steroidal estrogenic mycotoxin that induces severe health disturbances in humans and animals. This study aimed to determine the bioactive compounds in Costus speciosus extract (CSE) using GC-MS and evaluate its protective capability against ZEN-induced oxidative damage, genotoxicity, and cytotoxicity in rats. Six groups of male Sprague Dawley rats were treated orally for 15 days including the control group, CSE-treated groups at low (200 mg/kg b.
