Abstract The presynaptic serotonin transporter (SERT) clears extracellular following vesicular release to ensure temporal and spatial regulation of serotonergic signalling neurotransmitter homeostasis. Prescription drugs used treat neurobehavioral disorders, including depression, anxiety, obsessive-compulsive disorder, trap SERT by blocking the transport cycle. In contrast, illicit abuse like amphetamines reverse directionality, causing efflux. Both processes result in increased levels. By...

The human GABA transporter (GAT1) is a membrane that mediates the reuptake of neurotransmitter from synaptic cleft into neurons and glial cells. Dysregulation transport cycle has been associated with epilepsy neuropsychiatric disorders, highlighting crucial role in maintaining homeostasis brain levels. GAT1 secondary active couples movement substrate to simultaneous sodium chloride ions along their electrochemical gradients. Using MD simulations, we identified novel recruiting site at...

The serotonin transporter (SERT) is a member of the Solute Carrier 6 (SLC6) family and responsible for maintaining appropriate level in brain. Dysfunction SERT has been linked to several neuropsychiatric disorders, including depression, anxiety obsessive-compulsive disorder. Therefore, an in-depth understanding mechanism on atomistic level, coupled with quantification dynamics associated free energies required. Here, we constructed Markov state models (MSMs) from extensive unbiased molecular...

Abstract The interaction between two nitrosyl ruthenium complexes [Ru (NH.NHq–COOH)(tpy)NO](PF 6 ) 3 (RuBDQ) and (NH.NHq–H)(tpy)NO](PF (RuBD) human serum albumin (HSA) was investigated using spectroscopic computational methods. From fluorescence experiments, a dynamic quenching mechanism binding constants at single site demonstrated the higher stability of RuBDQ–HSA system 308 K compared with RuBD–HSA. Thermodynamic parameters indicated that RuBDQ RuBD to HSA mainly driven by hydrophobic...

3,4-Methylenedioxymethamphetamine (MDMA, 'ecstasy') is re-emerging in clinical settings as a candidate for the treatment of specific neuropsychiatric disorders (e.g. post-traumatic stress disorder) combination with psychotherapy. MDMA psychoactive drug, typically regarded an empathogen or entactogen, which leads to transporter-mediated monoamine release. Despite its therapeutic potential, can induce dose-, individual-, and context-dependent untoward effects outside safe settings. In this...

Abstract The presynaptic serotonin (5HT) transporter (SERT) clears extracellular 5HT following vesicular release to ensure temporal and spatial regulation of serotonergic signalling neurotransmitter homeostasis. Clinically approved drugs used for the treatment neurobehavioral disorders, including depression, anxiety, obsessive-compulsive disorder that target SERT trap in outward-open state thus blocking transport cycle. In contrast, illicit abuse like amphetamines reverses directionality,...

If $K\subset\mathbb{R}^n$ is a convex body and $\Gamma_pK$ the $p$-centroid of $K$, $L_p$ Busemann-Petty centroid inequality states that $\vol(\Gamma_pK) \geq \vol(K)$, with equality if only $K$ an ellipsoid centered at origin. In this work, we prove inequalities for type functional $r$-mixed volume $1 \leq r < n$, establish as consequence, version inequality. \keywords{Convex body, Moment centroid} }
