The role of agomelatine in appetite regulation and body weight in rats

open access: yesExperimental Physiology, EarlyView.
Abstract The hypothalamic nuclei play a central role in the synthesis of anorexigenic and orexigenic neuropeptides, which are regulated by peripheral hormones, like leptin and ghrelin. Melatonergic receptors (MT1/MT2) are prominently expressed in the arcuate nucleus of the hypothalamus – an essential hub for appetite control – and in peripheral ...

Imposed expiratory resistance, dynamic hyperinflation and locomotor power and fatigue

open access: yesExperimental Physiology, EarlyView.
Abstract Expiratory flow limitation results in dynamic hyperinflation, dyspnoea and premature exercise intolerance. We aimed to measure whether expiratory resistance reduces locomotor power via limiting maximal voluntary motor activity, exacerbating muscle fatigue, or both.

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

open access: yesExperimental Physiology, EarlyView.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...

Molecular mechanism of human α1A-adrenoceptor inhibition by Mamba snake toxin AdTx1

open access: yesCommunications Biology
There is growing interest in peptide or small protein based drugs targeting G protein-coupled receptors (GPCRs) for improved subtype selectivity over small molecules. Naturally occurring toxins represent rich sources of such ligands.

Role of the thalamic parafascicular nucleus cholinergic system in the modulation of acute corneal nociception in rats [PDF]

open access: yesVeterinary Research Forum, 2011
The present study investigated the effects of microinjections of acetylcholine (a cholinergic agonist), physostigmine (a cholinesterase inhibitor), atropine (an antagonist of muscarinic cholinergic receptors) and hexamethonium (an antagonist of nicotinic

Quantitative surface field analysis: learning causal models to predict ligand binding affinity and pose. [PDF]

open access: yes, 2018
We introduce the QuanSA method for inducing physically meaningful field-based models of ligand binding pockets based on structure-activity data alone. The method is closely related to the QMOD approach, substituting a learned scoring field for a pocket ...

Isometric handgrip contraction increases tibialis anterior intrinsic motoneuron excitability in a dose‐dependent manner

open access: yesExperimental Physiology, EarlyView.
Abstract The contribution of persistent inward currents (PICs) to motoneuron firing in the lower limb typically increases after a remote handgrip contraction, believed to result from diffuse serotonergic input increases in spinal cord. We investigated whether handgrip contraction intensity, duration and/or impulse would affect PIC estimates in tibialis
