Sesame oil has been exhibited to have anti-in ammatory and antioxidant in uences. The goal of this experiment was to look into sesame oil's hepato-protective properties and underlying processes in valproic acid-induced hepatotoxicity. Molecular docking was carried out to clarify the functional and structural underlying mechanism of sesame oil ameliorative effect. Mice were given 8 ml/kg/day of sesame oil (orally) and 100 mg/kg/day of valproic acid (i.p.) for 21 days. The results revealed that valproic acid caused a considerable increase in hepatic malondialdehyde (MDA) levels while decreasing the activity of glutathione peroxidase (GPx) enzyme. There was also a signi cant rise in serum levels of interleukines 1β & 6 (IL-1β & IL-6) and a signi cant decrease in hepatic (PXR) gene expression level.Sesame oil co-administration with valproic acid signi cantly normalized the antioxidant and antiin ammatory status and upregulated the gene expression level of PXR. In silico docking analysis results con rmed these results. This study concluded that supplementation of sesame oil attenuated valproic acid induced oxidative stress and in ammation. Hence, it was recommended as a dietary supplement for protection against valproic acid induced hepatotoxicity.

Background Cisplatin is a wide-ranging antineoplastic drug. Neurotoxicity is one of cisplatin’s side effects that restrict its usage. This study aimed to investigate the possible protective properties of sweet basil oil against cisplatin-induced neurotoxicity in mice. A docking study was carried out to elucidate the fundamental mechanism of sweet basil oil’s ameliorative influence. Thirty male mice were allocated into three groups as follows: control group, cisplatin group (2.3 mg/kg), and sweet basil oil group (25 µl/kg basil oil + cisplatin 2.3 mg/kg). Cisplatin was given for five successive days, followed by five days of rest, for two cycles, while sweet basil oil was orally administered for 21 successive days. Results Our results revealed that sweet basil oil’s antioxidant activity ameliorated the oxidative stress induced by cisplatin in mice’s brains via lowering MDA levels and increasing CAT activity and Nrf2 levels. Also, the anti-apoptotic activity of sweet basil oil was obvious via lowering the gene expression levels of Bid and caspase-3 but did not affect the serum level of P38 MAPK. Changes in acetylcholinesterase activity, serotonin and dopamine levels induced by cisplatin were significantly alleviated by sweet basil oil. Conclusion Sweet basil oil can be used as a food supplement to guard against cisplatin-induced neurotoxicity. Graphical abstract

Osteoarthritis (OA) represents the highest degenerative disorder. Because cartilage erosion is a common pathological alteration in OA, targeting some key metalloproteinases such as MMP-3, ADAMTS-5 besides their inhibitor TIMP-3 by natural products, could be an effective strategy to protect against osteoarthritis. Forty female Wister rats were categorized into five equal groups. Control, osteoarthritic (OA) (monosodium iodoacetate (MIA) 2 mg/50 µL saline, single intra-articular injection), OA+ indomethacin (2 mg/kg/daily/orally), OA+ nano-naringenin (25 mg/kg/daily/orally), and OA+ Amphora coffeaeformis (772 mg/kg/daily/orally). Treatments were initiated on the 8th day after osteoarthritis induction and continued for 28 days thereafter. Finally, blood and knee joint samples were collected from all rats for biochemical and histopathological evaluations. The current study showed that MIA induced oxidative stress, which resulted in changes in the inflammatory joint markers associated with increased right knee diameter and higher clinical scores for lameness. Amphora coffeaeformis followed by nano-naringenin exhibited a potential anti-arthritic activity by reducing the concentrations of serum MMP-3, ADAMTS-5, and joint MDA and increasing the levels of serum TIMP-3 and joint GSH, similar to indomethacin. The histopathological results confirmed these outcomes. In conclusion, Amphora coffeaeformis and nano-naringenin can be considered as natural therapeutic agents for osteoarthritis owing to their antioxidant and anti-inflammatory activities.
