Effects on the Depressive-like Behavior of MPTP-Exposed Female Rats: Apoptosis and α-Synuclein Modulation.

Parkinson's disease (PD) is a neurodegenerative disorder marked by motor deficits and non-motor symptoms, such as depression, which are associated with dopaminergic loss and α-synuclein aggregation in the brain. This study investigated the neuroprotective effects of a hydroalcoholic extract of the purple fruit of (PFEU) on motor ability and depressive-like behaviors in a PD model induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in female Wistar rats. Rats received intranasal administration of MPTP or vehicle, followed by 14 days of oral administration of PFEU (300 or 2000 mg/kg, administered once daily) or vehicle.

Chemistry to cognition: Therapeutic potential of (m-CF-PhSe) targeting rats' striatum dopamine proteins in amphetamine dependence.

Amphetamine (AMPH) abuse represents a major global public health issue, highlighting the urgent need for effective therapeutic interventions to manage addiction caused by this psychostimulant. This study aimed to assess the potential of m-trifluoromethyl-diphenyldiselenide [(m-CF-PhSe)] in preventing the addictive effects induced by AMPH through targeting dopamine metabolism proteins. (m-CF-PhSe) is of interest due to its demonstrated efficacy in mitigating opioid abuse, establishing it as a promising candidate for addiction treatment research.

Chrysin modulates the BDNF/TrkB/AKT/Creb neuroplasticity signaling pathway: Acting in the improvement of cognitive flexibility and declarative, working and aversive memory deficits caused by hypothyroidism in C57BL/6 female mice.

Hypothyroidism is known to affect memory consolidation, and our prior research highlighted the potential of chrysin as a therapeutic agent to restore cognitive function. The present study aimed to investigate the action mechanism of chrysin on memory deficits in hypothyroid in C57BL/6 female mice. We assessed cognitive flexibility, declarative, working, and aversive memories while analyzing the BDNF/TrkB/AKT/Creb neuroplasticity signaling pathway and synaptic function in the hippocampus and prefrontal cortex.

Antimicrobial Effect of Diphenyl Ditelluride (PhTe) in a Model of Infection by in .

Diphenyl ditelluride (PhTe), an organotelluric compound with pharmacological and toxicological attributes, has shown promise in microorganism studies. , an alternative animal model, is gaining popularity for novel antimicrobial research due to its cost-effectiveness, versatility, and similarity to vertebrate models. Given the rising antibiotic resistance, particularly in (), the exploration of novel antimicrobials is of utmost importance.

p-Coumaric acid potential in restoring neuromotor function and oxidative balance through the Parkin pathway in a Parkinson disease-like model in Drosophila melanogaster.

p-Coumaric acid is a significant phenolic compound known for its potent antioxidant activity. Thus, this study investigated the effects of p-coumaric acid on the behavioral and neurochemical changes induced in Drosophila melanogaster by exposure to rotenone in a Parkinson disease (PD)-like model. The flies were divided into four groups and maintained for seven days on different diets: a standard diet (control), a diet containing rotenone (500 μM), a control diet to which p-coumaric acid was added on the fourth day (0.
