D-galactose (D-gal) induced senescence in rodents is a widely used model for assessment of molecules affecting brain ageing. Chronic administration of D-gal causes neuroinflammation leading to cognitive deficit and memory impairment which represent Alzheimer's dementia. In present study, we investigated the neuroprotective effects of the natural phenol, p-Coumaric acid (PCA) and its underlying mechanism in the chronic D-gal treated mice.

Here, we aimed to evaluate the underlying mechanisms for the neuroprotective effect of NaHS, a known HS donor, against lipopolysaccharide (LPS)-induced memory impairment (MI). All the treatments were administered for 28 days, and LPS (0.

Systemic administration of lipopolysaccharide (LPS) induces neuroinflammation resulting in memory impairment (MI) and cognitive decline. In this study, we evaluated whether prophylactic administration of Rosmarinic acid (RA), a naturally occurring compound, exerts a neuroprotective effect in LPS-induced MI and cognitive decline.

Insulin signaling is impaired in AD brains due to insulin resistance, ultimately resulting in the formation of neurofibrillary tangles (NFTs). AD and T2DM are connected at molecular, clinical, and epidemiological levels making it imperative to understand the contribution of T2DM, and other metabolic disorders, to AD pathogenesis.

Nonalcoholic fatty liver disease (NAFLD) is regarded as the hepatic manifestation of the metabolic syndrome. It begins with the accumulation of fat in the liver (simple steatosis), which if untreated can progress to nonalcoholic steatohepatitis, cirrhosis, and hepatocellular carcinoma. Chrysin is a flavonoid present in bee propolis and many other plants.

Currently available therapies have limitations; hence there is a need to screen new molecules. Plumbagin is a naphthoquinone present in the roots of Plumbago species which has hypolipidemic and hepatoprotective activities.

There are reports describing the beneficial effects of Imperatorin (IMP), a naturally occurring furanocoumarin in central nervous system (CNS) disorders such as anxiety and epilepsy.
Objective: In the current study, we investigated whether IMP protects against LPS mediated memory deficits and neuroinflammation.
Background: Gentamicin is widely used as an antibiotic for the treatment of gram negative infections. Evidences indicates that oxidative stress is involved in gentamicin-induced nephrotoxicity. In Ayurvedic medicine, Punica granatum Linn.

Objective: This study was aimed to evaluate the effect of curcumin and ellagic acid on the activity of monoamine oxidase (MAO), the enzyme responsible for metabolism of monoamine neurotransmitters which are pivotal for neuronal development and function.
In view of the reports that nitric oxide modulates the neurotransmitters implicated in obsessive-compulsive disorder (OCD), patients with OCD exhibit higher plasma nitrate levels, and drugs useful in OCD influence nitric oxide. Agmatine is a polyamine and widely distributed in mammalian brain which interacts with nitrergic systems. Hence, the present study was carried out to understand the involvement of nitrergic systems in the anticompulsive-like effect of agmatine.
