Berberis lycium (family Berberidaceae) grows in district Sherani, Balochistan, Pakistan. It is used for the treatment of various disorders by the people of Balochistan. The present work was carried out to explore analgesic and neuropharamcological activities of crude methanolic extracts of B. lyceum. The analgesic activity was carried out by acetic acid induced writhing test and formalin test. Open field test, cage crossing test, rearing test, traction test and forced swimming test were carried out in neuropharmacological activities. The results reveal that crude methanolic extracts of B. lyceum showed significant (P<0.05) analgesic activity in acetic acid induced pain as well as with formalin test. In neuropharmacological activities, crude methanolic extracts of B. lyceum showed significant (P<0.05) central nervous system depressant activity and in forced swimming test it showed anxiolytic effects.

Background: Psychostimulants and nonstimulants have partially overlapping pharmacological targets on attention-deficit/hyperactivity disorder (ADHD), but whether their neuroimaging underpinnings differ is elusive. We aimed to identify overlapping and medication-specific brain functional mechanisms of psychostimulants and nonstimulants on ADHD.
Methods: After a systematic literature search and database construction, the imputed maps of separate and pooled neuropharmacological mechanisms were meta-analyzed by Seed-based Mapping toolbox, followed by large-scale network analysis to uncover potential coactivation patterns and meta-regression analysis to examine the modulatory effects of age and sex.

Diabetes mellitus is one of the metabolic syndromes that is associated with cognitive deficit, dementia, and Alzheimer's disease (AD) like pathology due to impaired insulin-signalling in the brain, oxidative stress and mitochondrial dysfunction. Nanotechnology is one of the most promising techniques for targeting the brain. However, the toxicity of metal nanoparticles is one of the biggest challenges to be studied.

Monoterpene indole alkaloids (MIAs) are valuable metabolites produced in numerous medicinal plants from the Apocynaceae family such as Alstonia scholaris, which synthesizes strictamine, a MIA displaying neuropharmacological properties of a potential importance. To get insights into the MIA metabolism in A. scholaris, we studied here both the spatial and transcriptional regulations of MIA genes by performing a robust transcriptomics analysis of the main plant organs, leaf epidermis but also by sequencing RNA from leaves transiently overexpressing the master transcriptional regulator MYC2.
