“…Moreover, several animal models have shown a role of Hcy in cerebrovascular pathology, cognitive decline and learning disabilities (24). Additionally, in our previous reports, we demonstrated the neuroprotective effects of the polyphenolic antioxidant agent, Curcumin, against Hcy-induced cognitive impairment and oxidative stress in the rat (25). In previous reports by our research group, Hcy decreased locomotor activities significantly in rats as well as it could induce apoptosis in substantia nigra cells (26).…”

Abstract. Recent investigations indicated that morphine has protective effects in different ischemia/reperfusion models and may protect against neuronal cell death, while other evidence showed that morphine induces apoptosis in neurons. Therefore, the current study was conducted to investigate preand post-conditioning effects of morphine on hippocampal cell apoptosis in a rat model of homocysteine (Hcy)-induced oxidative stress. In the present study, 0.5 µmol/µl Hcy was injected into bilateral intrahipocampal in the rat brain and morphine at a therapeutic dose of 10 mg/kg was injected intraperitoneally 5 days before and after Hcy injection in rats. The left and right rat hippocampus were removed for biochemical and histopathological analysis. In addition, hippocampal cell apoptosis was assayed by the TUNEL kit. Our results indicated that malondialdehyde (MDA) and superoxide anion (SOA) levels in the Hcy group were increased significantly compared to the control group (P<0.001). In addition, morphine pre-and post-treatment increased the MDA and SOA levels significantly in rat hippocampus compared with other groups (P<0.001). It was found that Hcy alone induced apoptosis in hippocampus cells and significantly increased the number of TUNEL-positive cells in rat hippocampus compared to the other group (P<0.001). Notably, our results indicated that pre-and post-treatment by morphine increased apoptosis in hippocampus cells compared with the other group (P<0.001). In conclusion, morphine neuroprotection and neurotoxicity needs to be further investigated to determine morphine side-effects in medical applications and to identify new targets for potential therapies.

“…Several studies show that curcumin can exert powerful oxygen free radical-scavenging effect and exhibit neuroprotective effect against oxidative damage in nervous system [36][37][38][39] . Curcumin may protect cortical neurons from tert-butyl hydroperoxide (t-BHP)-induced apoptosis in rat cortical neurons [40] .…”

Aim: Appoptosin (SLC25A38) is a pro-apoptotic protein, which is upregulated in Alzheimer's disease (AD) brains and plays an important role in promoting the pathological progress of AD. The aim of this study was to investigate the effects of curcumin from the rhizome of Curcuma longa on appoptosin-induced apoptosis in SH-SY5Y cells. Methods: SH-SY5Y cells were pretreated with curcumin, then transfected with appoptosin or vector. The apoptotic cells were detected with Annexin V staining analysis by flow cytometry. The expression of cleaved caspase-3, appoptosin, heme oxygenase-1 (HO-1) was examined using Western blotting. Intracellular level of ROS was measured with DCFH-DA staining by flow cytometry analysis. Mitochondrial membrane potential (ΔΨm) was detected with JC-1 staining under a fluorescence microscope and quantified by fluorescence ratio detection. Results: Overexpression of appoptosin in SH-SY5Y cells markedly increased cell apoptosis accompanied by reduced HO-1 expression, increased intracellular heme level, ROS overproduction and ΔΨm impairment. Treatment of SH-SY5Y cells with curcumin (2.5-20 μmol/L) for 24 h did not significantly affect their viability. However, pretreatment with curcumin (2.5-20 μmol/L) dose-dependently attenuated all above-mentioned pathological changes in appoptosin-transfected SH-SY5Y cells. Conclusion: Curcumin inhibits appoptosin-induced apoptosis in SH-SY5Y cells by upregulating the expression of HO-1, reducing the production of intracellular heme and ROS, and preventing the ΔΨm loss.

“…From the perspective of the data presented in this paper, it is important that foods rich in a broad array of polyphenols, such as from tart cherries, [5][6][7] wild blueberries, 20 Concord grapes, 21 and green tea, 22 have been found to have anti-nociceptive effects. Isolated compounds studied for their anti-nociceptive effects include resveratrol, 23,24 curcumin, 25 and clorogenic acid. 26 The most direct mechanism of action proposed for explaining this effect is the COX-2 inhibition by such compounds; however, other mechanisms probably contribute as well.…”

Dietary interventions involving antioxidants are of interest for reducing inflammation, improving joint motion, and altering pain perception. We evaluated the effect of oral consumption of a fruit and berry blend on pain and range of motion (ROM). This open-label clinical pilot study involved 14 study participants with limitations in ROM that was associated with pain and affected daily living. Participants included but were not limited to those with age-related osteoarthritis. Study participants consumed 120 mL MonaVie Active Ò fruit juice, predominantly containing açai pulp (Euterpe oleracea Mart.) and other fruit concentrates, daily for 12 weeks. Study participants were assessed at baseline and 2, 4, 8, and 12 weeks by structured nurse interviews, pain and activities of daily living (ADL) questionnaires, blood samples, and ROM assessment. Pain was scored by using a visual analogue scale. ROM was assessed by using dual digital inclinometry as recommended by American Medical Association guidelines. Consumption of the juice resulted in significant pain reduction, improved ROM measures, and improvement in ADLs. Serum antioxidant status, as monitored by the cell-based antioxidant protection in erythrocytes (CAP-e) assay, was improved within 2 weeks and continued to improve throughout the 12 weeks of study participation (P < .01). The inflammatory marker C-reactive protein was reduced at 12 weeks, but this change did not reach statistical significance. Lipid peroxidation decreased mildly at 12 weeks. The antioxidant status, as measured by the CAP-e bioassay, showed the best correlation with improvements in physical well-being (pain, ROM, and ADL). The significant association among increased antioxidant status, improved ROM, and pain reduction warrants further study.
