Appearance of antidepressant-like effect by sildenafil in rats after central muscarinic receptor blockade: evidence from behavioural and neuro-receptor studies
(Springer, 2008)The phosphodiesterase (PDE) 5 inhibitor sildenafil has been shown to display psychotropic actions in humans and animals, and has been used for the treatment of antidepressant-associated erectile dysfunction. However, its ... -
Asymmetric dimethylarginine and l-homoarginine prospectively relate to carotid wall thickness in a South African cohort
(Springer, 2020)Background and aims The L-arginine derivatives asymmetric (ADMA) and symmetric dimethylarginine (SDMA), as well as L-homoarginine may have opposing effects in the pathogenesis of atherosclerosis. We aimed to investigate ... -
Corticolimbic changes in acetylcholine and cyclic guanosine monophosphate in the Flinders Sensitive Line rat: a genetic model of depression
(Cambridge, 2012)Objective: Depression is suggested to involve disturbances in cholinergic as well as glutamatergic pathways, particularly the N-methyl-d-aspartate receptor-mediated release of nitric oxide (NO) and cyclic guanosine ... -
Ethnic disparity in defensive coping endothelial responses: the SABPA study
(Elsevier, 2015)Objectives: Defensive coping (DefS) in Blacks has been associated with greater cardiovascular risk than in their White counterparts. We examined associations between endothelial function mental stress responses and markers ... -
Is major depressive disorder a metabolic encephalopathy?
(Wiley, 2008)Metabolic encephalopathy is an acute disturbance in cellular metabolism in the brain evoked by conditions of hypoxia, hypoglycaemia, oxidative stress and/or inflammation. It usually develops acutely or subacutely and is ... -
Ketamine and aminoguanidine differentially affect Bdnf and Mtor gene expression in the prefrontal cortex of adult male rats
(Elsevier, 2017)The rapid and sustained antidepressant properties of ketamine provide evidence of the importance of the glutamatergic system in the neurobiology of depression. The antidepressant-like effects of ketamine are dependent on ... -
Metabotropic and ionotropic glutamate receptors as neurobiological targets in anxiety and stress-related disorders: focus on pharmacology and preclinical translational models
(Elsevier, 2012)Anxiety disorders are amongst the most common and disabling of psychiatric illnesses and have severe health and socio-economic implications. Despite the availability of a number of treatment options there is still a strong ... -
Methylene blue analogues with marginal monoamine oxidase inhibition retain antidepressant-like activity
(ACS, 2018)Methylene blue (MB) possesses diverse medical applications. Among these, MB presents with antidepressant-like effects in animals and has shown promise in clinical trials for the treatment of mood disorders. As an antidepressant, ... -
Nitric oxide involvement in the antidepressant-like effect of ketamine in the Flinders sensitive line rat model of depression
(Cambridge Univ Press, 2015)Objective: We investigated whether the nitric oxide (NO) precursor, L-arginine, can prevent the antidepressant-like action of the fast-acting antidepressant, ketamine, in a genetic rat model of depression, and/or induce ... -
Nitric oxide-related markers link inversely to blood pressure in black boys and men: the ASOS and African-PREDICT studies
(Springer, 2020)Nitric oxide plays an important role in maintaining endothelial function, while increased oxidative stress may lead to nitric oxide inactivation and cardiovascular disease. If nitric oxide biosynthesis/bioavailability is ...
