Acetate attenuates hypothalamic pyroptosis in experimentally induced polycystic ovarian syndrome.

This study hypothesized that SCFA, acetate impacts positively on hypothalamic pyroptosis and its related abnormalities in experimentally induced PCOS rat model, possibly through NrF2/HIF1-α modulation. Eight-week-old female Wister rats were divided into groups (n = 5), namely control, PCOS, acetate and PCOS + acetate groups. Induction of PCOS was performed by administering 1 mg/kg body weight of letrozole for 21 days.

The monoaminergic pathways are involved in the antidepressant-like effect of quercetin.

Quercetin, a plant-derived flavonoid, is an antioxidant and has demonstrated antidepressant and anti-inflammatory activities in several animal models. However, there is scanty information on the underlying mechanisms of its antidepressant property. This present study aimed at assessing the involvement of monoaminergic systems in the antidepressant-like activity of quercetin in experimental animals.

Quercetin abrogates lipopolysaccharide-induced depressive-like symptoms by inhibiting neuroinflammation via microglial NLRP3/NFκB/iNOS signaling pathway.

Background: Major depressive disorder is a serious psychiatric illness having serious damaging effect on the quality of life of suffers. Quercetin is a plant flavonoid, mostly used as a constituent in dietary products. This study evaluated antidepressant effect of quercetin on lipopolysaccharide (LPS)-induced depression in rats.

Psychobiotic interventions attenuate chronic alcohol use-mediated exacerbation of posttraumatic stress disorder in rats: the role of gut-liver axis response.

Objectives: The incidence of co-occurring alcohol-use disorder (AUD) and post-traumatic stress disorder (PTSD) is high, and the presence of one disorder aggravates the severity of the other. Emerging evidence shows the neuroprotective and anti-inflammation functions of psychobiotics. Hence, the study explored the effects of probiotics and synbiotic inulin on the gut- and liver-oxidative and inflammatory biomarkers in chronic alcohol exacerbation of PTSD symptoms in rats.

Fermented maize slurry (Ogi) and its supernatant (Omidun) mitigate elevated intraocular pressure by modulating BDNF expression and glial plasticity in the retina-gut axis of glaucomatous rats.

Objectives: Growing interest has been reported on the health benefits of fermented foods, which includes cognition enhancement and inflammation attenuation. BDNF is a known protectant against retinal degeneration, however, therapies that target this neurotrophic factor has been limited. Therefore, we assessed the reaction of BDNF and glial cells in glaucomatous rats and their response to treatment with fermented maize products.

Protective Effects of Morin Hydrate on Acute Stress-Induced Behavioral and Biochemical Alterations in Mice.

Introduction: As stress affects the brain both physiologically and chemically, researchers try to find novel anti-stress compounds with beneficial therapeutic effects. In this regard, the effect of stress and its modulation by Morin hydrate was studied using different acute models in mice.

Methods: The models employed were anoxic tolerance, swimming endurance, and acute restraint test.

Morin hydrate mitigates rapid eye movement sleep deprivation-induced neurobehavioural impairments and loss of viable neurons in the hippocampus of mice.

Rapid eye movement sleep deprivation distorts the body's homeostasis and results in oxidative breakdown which may be responsible for a variety of neurological disorders. Some naturally occurring compounds of plant origin with antioxidant and neuroprotective properties are known to attenuate the detrimental effects of REM sleep deprivation. Morin hydrate, a flavonoid from Mulberry has demonstrated antioxidant and neuroprotective activities but its effect in sleep disturbed mice is unknown.

Methyl jasmonate attenuated lipopolysaccharide-induced depressive-like behaviour in mice.

Depression is a recurrent neuropsychiatric disorder that affects millions of individuals worldwide and impact negatively on the patients' social functions and quality of life. Studies have shown that i.p injection of lipopolysaccharide (LPS) induces depressive-like behavior in rodents via induction of oxidative stress and neuroinflammation.

Possible Mechanisms Involved in Attenuation of Lipopolysaccharide-Induced Memory Deficits by Methyl Jasmonate in Mice.

This present study was carried out to investigate the likely mechanisms by which methyl jasmonate (MJ), 'an agent widely used in aromatherapy for neurological disorders, attenuates lipopolysaccharide (LPS)-induced memory deficits in mice. Mice were given intraperitoneal administration of LPS (250 µg/kg) alone or in combination with MJ (10-40 mg/kg), donepezil, DP (1 mg/kg), or vehicle for 7 successive days. Thereafter, memory was assessed using object recognition test (ORT).

Antinociceptive property of Olax subscorpioidea Oliv (Olacaceae) extract in mice.

Ethnopharmacological Relevance: Olax subscorpioidea is a shrub or tree found in Nigeria, and other parts of Africa. It is used in the management of inflammatory disorder, mental illness, convulsion, pain, and cancer. However, there is dearth of information on scientific basis for its folkloric use in the management of pain.

Pharmacological evaluation of the analgesic and anxiolytic activities of Jobelyn® in mice.

Abstract Background: This study presents the results of the pharmacological evaluation of the analgesic and anxiolytic potentials of Jobelyn®, a potent antioxidant African herbal formulation, in mice. The analgesic effect was assessed utilizing acetic acid-induced writhing, tail immersion and formalin-induced paw licking pain models. The anxiolytic activity was evaluated using elevated-plus maze (EPM) and light/dark box.
