AI Article Synopsis
- Aspidosperma pyrifolium has potential therapeutic effects against Parkinson's disease, focusing on its neuroprotective, antioxidant, and anti-inflammatory properties using the APSE-Aq fraction.
- In a study using male Wistar rats, APSE-Aq treatment improved behavioral changes and reversed harmful biochemical markers related to dopamine levels and inflammation after neurotoxic injury.
- These findings suggest that APSE-Aq could be beneficial in Parkinson's treatment due to its chemical relation to salicylic acid.
Article Abstract
Objectives: Aspidosperma species are used for several diseases, especially for malaria in Brazil. Although the genus is object of pharmacological studies, almost none are found on Aspidosperma pyrifolium. We investigate neuroprotective, antioxidant and anti-inflammatory properties of the APSE-Aq fraction (benzoic acid glycosylated derivative) on Parkinson's disease model.
Methods: Male Wistar rats were subjected to a 6-hydroxydopamine injection into the right striatum and treated or not with APSE-Aq (100 or 200 mg/kg, p.o.). The sham-operated group was injected with saline. Two weeks later, animals were subjected to behavioural, neurochemical and immunohistochemical evaluation. The data were analysed by ANOVA and Tukey test.
Key Findings: The APSE-Aq-treated group shows a partial recovery of behavioural changes as compared with the untreated-6-hydroxydopamine group. A partial recovery was also observed in nitrite contents and lipid peroxidation. APSE-Aq treatments significantly reversed decreases in striatal dopamine and metabolites in the untreated 6-hydroxydopamine group. Immunostainings for markers as tyrosine hydroxylase and dopamine transporter decreased in the untreated 6-hydroxydopamine group and values recovered after APSE-Aq treatments. Similar data were seen for TNF-alpha.
Conclusion: APSE-Aq presents neuroprotective, antioxidant and anti-inflammatory activities. Considering that APSE-Aq is chemically related to salicylic acid, it may act on similar targets.

The treatment of fungal keratitis(FK) remains challenging due to delayed fungal detection and the limited effectiveness of antifungal drugs. Fungal infection can activate both innate and adaptive immune responses in the cornea. Fungi stimulate the production of oxidative stress-related biomarkers and mediate the infiltration of neutrophils, macrophages, and T cells.

Introduction: Cerebral ischemic strokes cause brain damage, primarily through inflammatory factors. One of the regions most affected by middle cerebral artery occlusion (MCAO) is the hippocampus, specifically the CA1 area, which is highly susceptible to ischemia. Previous studies have demonstrated the anti-inflammatory properties of quercetin.

This comprehensive review aims to explore and consolidate the current knowledge on dendrobine, including its biological activities, molecular mechanisms of action, effects on various physiological processes, potential toxicity, and safety considerations, in order to unlock its full potential in various applications. Dendrobine has diverse biological effects, including anti-inflammatory, antioxidant, neuroprotective, immunomodulatory, and anticancer effects. Dendrobine also exerts neuroprotective effects by boosting neuronal survival, reducing neuroinflammation, and regulating neurotransmitter release.

Serious neurological disorders were associated with cadmium toxicity. Hence, this research aimed to investigate the potential neuroprotective impacts of the ethanolic extracts of Citrus aurantium unripe fruits and leaves (CAF and CAL, respectively) at doses 100 and 200 mg/kg against cadmium chloride-provoked brain dysfunction in rats for 30 consecutive days. HPLC for natural pigment content revealed that CAF implied higher contents of Chlorophyll B, while the CAL has a high yield of chlorophyll A and total carotenoid.
