Neurotransmitter evaluation in the hippocampus of rats after intracerebral injection of TsTX scorpion toxin

Journal of Venomous Animals and Toxins including Tropical Diseases, 2009
TsTX is an α-type sodium channel toxin that stimulates the discharge of neurotransmitters from neurons. In the present study we investigated which neurotransmitters are released in the hippocampus after TsTX injection and if they are responsible for

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

Beyond a dual role: how Purpureocillium lilacinum reprograms citrus metabolism for integrated biocontrol and growth promotion

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Plants harbor complex microbial communities that are fundamental to their health and productivity. Among them, endophytic fungi such as Purpureocillium lilacinum establish mutualistic associations, offering dual benefits as plant growth promoters and biocontrol agents.

Genetic Etiologies of Dystonia with Anarthria/Aphonia

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Dystonia with anarthria and/or aphonia (DAnAp) represents a distinctive phenotype manifesting across lifespan. Frequently associated with genetic disorders, early recognition is critical for diagnosis and management. Objectives To provide practical recommendations for the clinical evaluation of patients with DAnAp, enhancing ...

Altered Cerebrospinal Fluid Tryptophan–Kynurenine Pathway Metabolism in Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Alterations in tryptophan–kynurenine (TRP‐KYN) metabolism, which is associated with neuroinflammation, remain unclear in multiple system atrophy (MSA). Objective The aim was to investigate cerebrospinal fluid (CSF) TRP metabolites in MSA and their associations with other biomarkers.

Thirty-Second Net Stressor Task in Adult Zebrafish

Bio-Protocol, 2015
Zebrafish have become a popular animal model for behavioral neuroscience (Gerlai, 2014). Recent studies have demonstrated that brief experimental handling prior to euthanizing animals can subsequently alter biological measures quantified post-mortem (e.g.

COVID‐19 Amplifies Sex‐Specific Dopamine and Glial Responses in a Parkinson's Disease Mouse Model

Movement Disorders, EarlyView.
Abstract Background Exposure to environmental agents, including viral infections, may increase Parkinson's disease (PD) susceptibility, especially in males, but the neurodegenerative risk extent of COVID‐19 remains uncertain. Objectives We investigated the plausible link between severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection and
