Therapeutic effects of repetitive transcranial magnetic stimulation in an animal model of Parkinson's disease.
In conclusion, rTMS treatment improved motor functions and survival of DA neurons, suggesting that the neuroprotective effect of rTMS treatment might be induced by upregulation of neurotrophic/growth factors in the PD animal model. PMID: 23998987 [PubMed - as supplied by publisher]

Adult hemiparkinsonian rats do not benefit from tactile stimulation.
Abstract Tactile stimulation (TS) applied to adult rats after cortical injury (medial frontal cortex aspiration or sensorimotor pial stripping stroke model) has been previously shown to ameliorate behavioral impairments and to improve morphological parameters like dendritic length of prefrontal cortical neurons (Gibb et al. Behav Brain Res 2010;214:102-7). The purpose of this study was to examine the effect of TS on healthy and hemiparkinsonian adult rats. Therefore, the animals received TS for 14 days and 15min three times daily. At different time points rats were tested in various behavioral tests (amphetamine-i...

The use of stimulant medications for non-core aspects of ADHD and in other disorders.
Abstract Psychostimulants play a central role in the management of ADHD. Here we review the evidence pertaining to the use of methylphenidate, dexamphetamine and related amphetamine salts, the prodrug lisdexamfetamine and modafinil for the management of comorbid ADHD and non-ADHD indications. There is a growing consensus that stimulant medications are helpful at improving the emotional dysregulation and lability, and oppositional and conduct symptoms that are often associated with ADHD. There is some evidence that psychostimulants may improve outcomes in those with treatment resistant depression, reduce negative s...

Methamphetamine-related brainstem haemorrhage
We report the case of an otherwise healthy 29-year-old woman who presented with a brainstem haemorrhage following intravenous methamphetamine use. Extensive investigation did not reveal an underlying pathology, and the development of symptoms was temporally related to methamphetamine injection. Although intracerebral haemorrhage secondary to methamphetamine use is well documented, this report describes a haemorrhage within the brainstem which is a rare location. While animal studies have demonstrated the potential of methamphetamines to produce brainstem haemorrhages, there has only been one previous report describing a ha...

Effects of monoaminergic drugs on training-induced motor cortex plasticity in older adults.
Abstract Primary motor cortex (M1) plasticity is involved in motor learning and stroke motor recovery, and enhanced by increasing monoaminergic transmission. Age impacts these processes but there is a paucity of systematic studies on the effects of monoaminergic drugs in older adults. Here, in ten older adults (age 61+ 4 years, 4 males), we determine the effects of a single oral dose of carbidopa/levodopa (DOPA), d-amphetamine (AMPH), methylphenidate (MEPH) and placebo (PLAC) on M1 excitability and motor training-induced M1 plasticity. M1 plasticity is defined as training related long lasting changes in M1 excitab...

CART modulates beta-amyloid metabolism-associated enzymes and attenuates memory deficits in APP/PS1 mice.
CONCLUSION: CART decreases the levels of soluble Aβ in the hippocampus of APP/PS1 mice by modulating the expression of Aβ metabolism-associated enzymes, which may be associated with the MAPK and AKT pathways. PMID: 28743230 [PubMed - as supplied by publisher]

Noradrenergic antagonists mitigate amphetamine-induced recovery.
Abstract Brain injury, including that due to stroke, leaves individuals with cognitive deficits that can disrupt daily aspect of living. As of now there are few treatments that shown limited amounts of success in improving functional outcome. The use of stimulants such as amphetamine have shown some success in improving outcome following brain injury. While the pharmacological mechanisms for amphetamine are known; the specific processes responsible for improving behavioral outcome following injury remain unknown. Understanding these mechanisms can help to refine the use of amphetamine as a potential treatment or l...

Features and Outcomes of Methamphetamine Associated Pulmonary Arterial Hypertension.
CONCLUSIONS: Meth-APAH is a severe and progressive form of PAH with poor outcomes. Future studies should focus on mechanisms of disease and potential therapeutic considerations. PMID: 28934596 [PubMed - as supplied by publisher]

Connecting Metainflammation and Neuroinflammation Through the PTN-MK-RPTP β/ζ Axis: Relevance in Therapeutic Development
Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroi...

The Discovery and Development of Liraglutide and Semaglutide
We describe one such approach, albumin binding, and explain how it was applied in the development of the human GLP-1 analog liraglutide once daily and, subsequently, semaglutide once weekly. The pharmacology of these two long-acting GLP-1 analogs, in terms of improving glycemic control, reducing body weight and decreasing cardiovascular (CV) risk, is also reviewed, together with some novel biology. In addition, we describe the importance of accurate target (GLP-1 receptor) tissue expression analysis. Now an established class of agents, GLP-1-based therapies represent a significant advance in the treatment of T2D. All curr...

C-Reactive Protein and Risk of Parkinson's Disease: A Systematic Review and Meta-Analysis
Conclusions: This meta-analysis revealed that PD is associated with an increase of CRP levels. CRP might be a risk factor for PD or PD leads to an inflammatory response. Introduction Parkinson's disease (PD) is one of the most complex neuro-degenerative disorders next to Alzheimer's disease. It is characterized by bradykinesia, tremor, rigidity, abnormal postural, and gait (1). PD has been recognized by the selective loss of dopaminergic neurons within the substantia nigra pars compacta, whereas the exact etiology remains elusive (2). Previously, multiple inferences have reviewed the environmental a...

Transcranial Direct Current Stimulation Use in Warfighting: Benefits, Risks, and Future Prospects
Conclusion The aim of this paper was to examine whether military tDCS use can be efficacious and ethical in military settings. Our assessment is that tDCS offers a number of cognitive, motor, and perceptual enhancement opportunities which could provide value in military situations like training and operations. There is potential scope for use in a number of key areas that directly affect practical battlefield advantage and survivability, such as deceptive capabilities, risk-taking, threat detection, perception, and physiological improvement. Additionally, tDCS has the potential to improve command and control decision maki...
