Reactive oxygen species (ROS) produced by cell metabolism have a duplex role in oxidation and inflammation reactions which involve damage or repair responses. Excess ROS production has detrimental effects on the survival of cells. We examined protective effect semi-natural compound NF2 (deacetylepoxyazadiradione), for its activity against free radical-mediated stress inflammatory response to lipopolysaccharide (LPS) using zebrafish larvae. Preliminary antioxidant assays indicated an increase scavenging radicals from than NF1 (Epoxyazadiradione) concentration-dependent manner. Cell cytotoxicity was determined rat myoblast lines (L6), more 95 % viability obtained. Zebrafish developmental toxicity test that is not toxic even at 150 μM. The percentage ROS, lipid peroxidation, nitric oxide apoptosis were reduced significantly treated LPS-stressed number employed macrophages treatment observed neutral red dye-marked macrophage localization images. Relative expression genes larvae after with increased. RT-PCR quantification anti-inflammatory gene decreased relative folds pro-inflammatory cytokines, iNOS increased mitochondrial (GR, GST GPx) LPS stressed NF2. From overall obtained results, it can be concluded oxidative caused LPS.

Parabens are synthetic antimicrobial compounds used as a preservative for extending the shelf life of food, pharmaceutical and cosmetic products. The alkyl chain length paraben esters positively correlates with their property. Hence, long-chain esters, namely butylparaben propylparaben, in combination they have better solubility efficacy. Extensive use parabens has now resulted ubiquitous presence these various human environmental matrices. During early life, exposure to contaminants is known cause oxidative-stress mediated apoptosis developing organs. brain being one high oxygen-consuming, metabolically active lipid-rich organ, it primarily susceptible reactive oxygen species (ROS) lipid peroxidation (LP) induced neuronal cell death. primary impairment cognitive emotional neurobehvioural outcomes neurodegenerative disease was found be associated apoptosis. present study aimed propylparaben's effect on zebrafish during embryonic stages. Besides this, association between alteration anxiety-like neurobehavioral response oxidative stress antioxidant status head region also studied. results showed variation toxic signature left by propylparaben developmental parameters such hatching rate, survival non-lethal malformations time-dependent manner. Data from light-dark preference test trigger behavior larvae. In addition, significant increase intracellular ROS LP levels correlated suppressed enzymes: superoxide dismutases (SOD), catalases (CAT), Glutathione peroxidase (GPx), glutathione S-transferase (GST), (GSH) activity Acetylcholinesterase (AChE) exposed groups, along increased nitric oxide production. overall observations show indices correlating upregulated expression apoptotic cells dose-dependent Collectively, our findings reveal an anxiogenic neuroactive compound capable inducing through mechanism involving oxidative-stress-induced larvae, which suggests potential hazard this can extrapolated health well.

Alzheimer's disease (AD) is a neurodegenerative disorder that associated with abnormal cognition. AD aided in its initiation and progression by hereditary environmental factors. Aluminum (Al) neurotoxic agent causes oxidative stress, which linked to progression. Additionally, Nrf2/HO-1, APOE4/LRP1, Wnt3/β-catenin, TLR4/NLRP3 are the main signaling pathways involved pathogenesis. Several phytochemicals promising options delaying evolution.This study aimed at studying neuroprotective effects of some as morin (MOR), thymol (TML), thymoquinone (TMQ) on physical mental activities (PhM) Al chloride (AlCl3)-induced rat model. Another objective was determine specificity using molecular docking.Eighty male Dawley rats were divided into eight groups. Each group received: saline (control group), AlCl3, (ALAD), PhM, either alone or combination MOR, TML, and/or TMQ for five weeks. Animals then subjected behavioral evaluation. Brain tissues used histopathological biochemical analyses extent neurodegeneration. The effect AlCl3-induced stress also investigated.AlCl3 caused decline spatial learning memory, well changes brains rats. Phytochemicals combined PhM restored antioxidant activities, increased HO-1 Nrf2 levels, blocked inflammasome activation, apoptosis, TLR4 expression, amyloide-β generation, tau hyperphophorylation. They brought ApoE4 LRP1 levels back normal regulated Wnt3/β-catenin/GSK3β pathway.The use strategy reducing modulating TLR4/NLRP3, Wnt3/β-catenin/GSK-3β pathways.

Oxidative stress causes disruption of cell macromolecules and resulting neurodegeneration when the antioxidant defense mechanism is inhibited. emerging as a key therapeutic target for nerve agent toxicity. Therefore, treatment methods are novel effective approach to attenuate oxidative neurodegeneration. This study evaluated neuroprotective ability short peptide, RW20 derived from histone acetyltransferases (HATs). Using bioinformatics tools, amino acid sequence RF13 peptide with activity was predicted HAT Channa striatus transcriptome. The synthesized at various concentrations (10–50 μM) analyzed in vitro vivo assay. effect H2O2 stressed zebrafish larvae. results showed by restoring enzymes including SOD, CAT, GPx, GSH, GST treated RW20. In addition, indicator lipid peroxidation gradually declined an increase concentration peptides. It also shown neuronal damage inhibiting nitric oxide overproduction, thus increasing AChE activity. Further, validate RW20, intracellular ROS level apoptosis larvae were incubating along which decreased reduced death. Overall, demonstrated that possessed prominent Hence, we conclude can be developed potent against stress-induced neurodegenerative diseases.
