Research ArticleOpen accessIn the keywordsAssessment of Neuropharmacological Activities of Terminalia Chebula in RatsWathita Phachonpai, Jintanaporn Wattanathorn, Terdthai Tong-un et al.Problem statement: Oxidative stress has been implicated in the pathophysiology of many neurodegenerative diseases such as Alzheimer’s Disease (AD). In traditional practices of Ayurvedic medicine, numerous herbs have been used to treat cognitive disorders. Terminalia Chebula (Combretaceae; TC), is a well-known Ayurvedic herbal remedy which possesses an antioxidant activity. The scientific literature strongly supports its in vitro exerted acetylcholinesterase inhibitory … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 2 · 11 Jun 2012 · 8,295 accessesView PDFCite
Research ArticleOpen accessIn the keywordsScreening Neuropharmacological Activities of Kaempferia parviflora (Krachai Dam) in Healthy Adult Male RatsThaneeya Hawiset, Supaporn Muchimapura, Jintanaporn Wattanathorn, Bungorn SripanidkulchaiProblem statement: Although the global prevalence of psychological disorders is increasing continually, the efficacies of therapeutic strategies are still very limited. Oxidative stress has been implicated in the pathogenesis of psychiatric disorders and substance possessing antioxidant activity can alleviate the mentioned conditions. Therefore, we hypothesized that Kaempferia parviflora, a medicinal plant claimed for nerve tonic, also possessed the neuropharmacological activities … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 8,697 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBio-Guided Study on Melastoma malabathricum Linn Leaves and Elucidation of its Biological ActivitiesMourouge Saadi Alwash, Nazlina Ibrahim, Wan Yaacob AhmadThe present study aimed to isolate and identify constituents with antibacterial activity from the Methanol extract of Melastoma malabathricum leaves (MMML) through bioassay guided fractionation. Furthermore, the study scoped to evaluate the cytotoxic effects of M. malabathricum leaves fractions for possible protective effect of antoxidative constituents present in the fractions. The MMML extract was fractionated by Vacuum Liquid Chromatography (VLC) … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 9,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccumulation and Effect of Manganese on Chloroplasts and Antioxidant Responses in Arabidopsis ThalianaJun Xing, Xue Yang, Cailing YuanIn this study, 5-day-old seedlings of Arabidopsis thaliana were exposed to 0, 0.5, and 1.0 mmol/L MnCl₂ for 6 days by using three independent biological replicates. The results indicated that Mn content in roots exhibited a dose-dependent increase with rising external Mn supply. The elevated Mn levels led to significant reductions in the nutrient content of K, Ca, Na, and … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 18 Jul 2026 · 824 accessesView PDFCite
Research ArticleOpen accessIn the abstractNitric Oxide Treatment Improves the Antioxidant Capacity While Inhibiting Anthocyanin Biosynthesis of Peach Fruit (‘Xiahui-8’) During RipeningZiqi Wang, Yanyan Li, Yingling Deng et al.Nitric Oxide (NO) is an important bioactive signal molecule that plays an important role in diverse physiological processes. This study aimed to explore the effects of Nitric Oxide (NO) treatments on postharvest peach fruit.

Research ArticleOpen accessIn the abstractAluminium-Induced Hepatotoxicity and the Protective Role of Withania somnifera (Ashwagandha) in Wistar RatsAnchana Babu, Rekha D Kini, Nayanatara Arun Kumar, Megha GokulAluminium is a widely distributed environmental contaminant whose chronic exposure leads to accumulation in multiple organs, including the liver, resulting in oxidative stress and tissue damage. When reactive oxygen species production exceeds the body's antioxidant defense capacity, cellular injury ensues — a mechanism central to aluminium-induced hepatotoxicity.
