A mathematical model of recombinase polymerase amplification under continuously stirred conditions
(Elsevier, 2016)Growing interest surrounds isothermal PCR techniques which have great potential for miniaturization for mobile diagnostics. Particularly promising, Recombinase Polymerase Amplification (RPA), combines this advantage of ... -
A single dose of vortioxetine, but not ketamine or fluoxetine, increases plasticity-related gene expression in the rat frontal cortex
(Elsevier, 2016)Ketamine is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist that has been shown to induce a rapid antidepressant effect in treatment-resistant patients. Vortioxetine is a multimodal-acting antidepressant ... -
Comparison of physiological parameters and anaesthesia specific observations during isoflurane, ketamine-xylazine or medetomidine-midazolam-fentanyl anaesthesia in male guinea pigs
(Public Library of Science, 2016)Guinea pigs (GPs) are difficult to anaesthetize successfully, the choices for anaesthesia are limited and physiological parameters are likely to be influenced substantially under anaesthesia. We implanted blood pressure ... -
Cardiovascular safety pharmacology studies in dogs enabled for a poorly soluble molecule using spray-dried dispersion: impact on lead selection
(Elsevier, 2016)The aim of this study was to identify an adequate formulation for a poorly soluble lead molecule (BI-A) that would achieve sufficiently high plasma concentrations after oral administration in dogs to enable a robust ... -
Neurovascular plasticity of the hippocampus one week after a single dose of ketamine in genetic rat model of depression
(Wiley, 2016)Glutamatergic system and the structural plasticity hypothesis are principal components for rapid and sustained antidepressant effects of novel antidepressant therapeutics. This study represents the first investigation of ... -
Potential involvement of serotonergic signaling in ketamine's antidepressant actions: a critical review
(Elsevier, 2016)A single i.v. infusion of ketamine, classified as an N-methyl-d-aspartate (NMDA) receptor antagonist, may alleviate depressive symptoms within hours of administration in treatment resistant depressed patients, and the ... -
Inhibition of human monoamine oxidase: biological and molecular modeling studies on selected natural flavonoids
(ACS, 2016)Naturally occurring flavonoids display a plethora of different biological activities, but emerging evidence suggests that this class of compounds may also act as antidepressant agents endowed with multiple mechanisms of ... -
Non-prescription sale and dispensing of antibiotics in community pharmacies in Zambia
(Taylor & Francis, 2016)Background: In Zambia, antibiotics are categorized as prescription-only medicines. Antibiotics dispensed without a prescription pose a public health threat, which is a concern. Consequently, the aim is to ascertain the ... -
Maximum potential cost-savings attributable to generic substitution of antipsychotics 2008 to 2013
(Elsevier, 2016)Background Schizophrenia is a costly illness to treat, especially during a time of escalating medicine inflation costs, putting a large economic strain on patients, their families and the community. Treatment, however, ... -

Discovery of 1,3-diethyl-7-methyl-8-(phenoxymethyl)-xanthine derivatives as novel adenosine A1 and A2A receptor antagonists
(Elsevier, 2016)Based on a previous report that a series of 8-(phenoxymethyl)-xanthines may be promising leads for the design of A1 adenosine receptor antagonists, selected novel and known 1,3-diethyl-7-methyl-8-(phenoxymethyl)-xanthine ... -
Perspectives and challenges of antioxidant therapy for atrial fibrillation
(Springer, 2017)Atrial fibrillation (AF) is the most common sustained arrhythmia associated with significant morbidity and mortality. The mechanisms underlying the pathogenesis of AF are poorly understood, although electrophysiological ... -
South Africa's salt reduction strategy: are we on track, and what lies ahead?
(HMPG (Health and Medical Publishing Group), 2017)On 2 September 2016, 25 local and international participants from various sectors met in Cape Town to take stock of South Africa (SA)’s progress in salt reduction and develop a roadmap for action. SA is centre stage on ... -
The expression of plasticity-related genes in an acute model of stress is modulated by chronic desipramine in a time-dependent manner within medial prefrontal cortex
(Elsevier, 2017)It is well established that stress plays a major role in the pathogenesis of neuropsychiatric diseases. Stress-induced alteration of synaptic plasticity has been hypothesized to underlie the morphological changes observed ... -
Inulin suitable as reduced-kilojoule carrier for production of microencapsulated spray-dried green Cyclopia subternata (honeybush) extract
(Elsevier, 2017)Retention of phenolic compounds during spray-drying of an anti-diabetic C. subternata extract and physicochemical characteristics of spray-dried powders (pure extract and extract-carrier mixtures) were evaluated. Extract-carrier ... -
Efflux as a mechanism of antimicrobial drug resistance in clinical relevant microorganisms: the role of efflux inhibitors
(Taylor & Francis, 2017)Introduction: Microbial resistance against antibiotics is a serious threat to the effective treatment of infectious diseases. Several mechanisms exist through which microorganisms can develop resistance against antimicrobial ... -
Synthesis and evaluation of 7-substituted coumarin derivatives as multimodal monoamine oxidase-B and cholinesterase inhibitors for the treatment of Alzheimer's disease
(Elsevier, 2017)A series of 7-substituted coumarin derivatives were designed and synthesised to display ChE and MAO-B inhibitory activity. The compounds consisted out of a coumarin structure (MAO-B inhibitor) and benzyl-, piperidine-, ... -
Benzyloxynitrostyrene analogues: a novel class of selective and highly potent inhibitors of monoamine oxidase B
(Elsevier, 2017)This study examines a series of novel 3-benzyloxy-β-nitrostyrene analogues as a novel class of inhibitors of the monoamine oxidase (MAO) enzymes. MAO inhibitors are considered useful for the treatment of depression and ... -
Selected C8 two-chain linkers enhance the adenosine A1/A2A receptor affinity and selectivity of caffeine
(Elsevier, 2017)Recent research exploring C8 substitution on the caffeine core identified 8-(2-phenylethyl)-1,3,7-trimethylxanthine as a non-selective adenosine receptor antagonist. To elaborate further, we included various C8 two-chain-length ... -
