Oxidative stress plays an important role in both the initiation and progression of Parkinson's disease (PD). Rotenone, an environmental toxin, induces oxidative stress and impact mitochondrial dynamics, including fission and fusion. Thymoquinone (TQ) has been reported to have antioxidant and anti-inflammatory characteristics in vitro and in vivo. TQ scavenges free radicals so prevents cell damage against oxidative agents. To evaluate the efficacy of TQ in the management of PD, male Wistar rats (8-10 months) received rotenone...

For almost a decade, there has been much interest in the development of chemical inhibitors of Polo-like kinase 1 (Plk1) protein interactions. Plk1 is a master regulator of the cell division cycle that controls numerous substrates. It is a promising target for cancer drug development. Inhibitors of the kinase domain of Plk1 had some success in clinical trials. However, they are not perfectly selective. In principle, Plk1 can also be inhibited by interfering with its protein interaction domain, the Polo-Box Domain (PBD)...

Thymoquinone (TQ), a major bioactive compound of Nigella sativa seeds has several therapeutic properties. The main drawback in bringing TQ to therapeutic application is that it has poor stability and bioavailability. Hence a suitable carrier is essential for TQ delivery. Recent studies indicate biodegradable polymers are potentially good carriers of bioactive compounds. In this study, polyethylene glycol (PEG) modified chitosan (Cs) nanocapsules were developed as a carrier for TQ. Aqueous soluble low molecular weight Cs and PEG was selected among different biodegradable polymers based on their biocompatibility and efficacy as a carrier...

Status epilepticus (SE), which can cause neuronal injury, neuronal death and alteration of neuronal networks, is characterized by high mortality and morbidity. Recently, inflammation was shown to play a significant role in SE pathogenesis. We also found that microRNA-146a was highly expressed in SE rats with severe inflammation. The role of miRNA-146a in the inflammatory response of SE is not clear. Thus, in our study, we investigated the relationship between inflammation and miR-146a expression. We assessed the effects of thymoquinone, an anti-inflammatory drug, and found it had a neuroprotective effect on SE by inhibiting the inflammatory reaction...
