A multifaceted exercise intervention did not alter cognitive function and cerebral perfusion in individuals with Parkinson's disease

Publication date: Available online 13 July 2019Source: Science &SportsAuthor(s): B.S. Pollock, C.A. Peacock, E.J. Ryan, M.B. Spitznagel, A.L. RidgelSummaryObjectivesTo investigate cerebral perfusion as a potential mechanism of exercise-related cognitive improvements and to further associate cognition and cerebral perfusion in Parkinson's disease.Equipment and methodsCerebral perfusion was measured continuously at rest and during a cognitive task using near-infrared spectroscopy before and after a multifaceted exercise program in thirteen individuals with Parkinson's disease.ResultsCognitive function was not significantly impaired in our group of Parkinson's disease participants at baseline. Cerebral perfusion (69.91% ± 2.43) was significantly greater during cognitive testing than while resting (68.12% ± 2.42) (P ≤ 0.001). Our results are inconclusive with respect to the effect of exercise on cognitive dysfunction in PD.RésuméObjectifsInvestiguer la perfusion cérébrale comme un mécanisme potentiel de l’amélioration cognitive liée à l’exercice et associer davantage la cognition et la perfusion cérébrale dans la maladie de Parkinson.Matériel et méthodesLa perfusion cérébrale a été mesurée en permanence au repos et au cours d’une tâche cognitive en utilisant la spectroscopie proche infraro...

In this study, analysis of antioxidant defense was performed on the blood samples from 184 "aged" individuals aged 65-90+ years, and compared to the blood samples of 37 individuals just about at the beginning of aging, aged 55-59 years. Statistically significant decreases of Zn,Cu-superoxide dismutase (SOD-1), catalase (CAT), and glutathione peroxidase (GSH-Px) activities were observed in elderly people in comparison with the control group. Moreover, an inverse correlation between the activities of SOD-1, CAT, and GSH-Px and the age of the examined persons was found. No age-related changes in glutathione reductas...

In conclusion, there is solid evidence that obesity deregulates cellular mechanisms related to nutrient sensing. Altered Intercellular Communication It is accepted that aging impacts the organism at the cellular level, but also decreases the capacity of cells of an organism to interact. During aging, there is a decreased communication at the neuronal, neuroendocrine, and endocrine levels. Two of the most compelling examples of impaired communication are inflammaging and immunosenescence. The inflammaging phenotype results in elevated cytokines. These cytokines can accelerate and propagate the aging process. T...

Many neurodegenerative conditions are associated with the accumulation of forms of metabolic waste in the central nervous system, protein aggregates that form solid deposits between or within cells. Tauopathies such as frontotemporal dementia are associated with tau aggregates, synucleinopathies such as Parkinson's disease with α-synuclein, and amyloidoses with varying forms of amyloid, such as the amyloid-β found in elevated amounts in Alzheimer's disease patients. Alzheimer's itself is an amyloidosis that also becomes a tauopathy in its later stages. These protein aggregates and their surrounding halos of harm...

Conclusions: This study presents the comparison of a voxel based analysis of 18F-DOPA PET/CT and MRI in glioma patients. The mismatch between 18F-DOPA and MRI parameters indirectly confirms the hypothesis of different biological parameters identified by 18F-DOPA and MRI.

AbstractThe herbicide paraquat (PQ) has been reported to enhance the risk of developing Parkinson ’s disease (PD) from epidemiological studies. PQ-induced reactive oxygen species (ROS) are linked with a selective loss of nigrostriatal dopaminergic neurons. Here, we first report a unique mechanism of nigrostriatal dopaminergic degeneration, in which rapid intracellular Zn2+ dysregulation via PQ-induced ROS production causes PD in rats. When the substantia nigra pars compacta (SNpc) of rats was perfused with PQ, extracellular concentrations of glutamate and Zn2+ were increased and decreased, respectively, in the SNpc. ...

In this study we aimed to determine whether DRD3-signalling is altered in peripheral blood CD4+ T-cells obtained from PD patients in comparison to healthy controls (HC). Furthermore, we evaluated the therapeutic potential of targeting DRD3 confined to CD4+ T-cells by inducing the pharmacologic antagonism or the transcriptional inhibition of DRD3-signalling in a mouse model of PD induced by the chronic administration of MPTP and probenecid (MPTPp). In vitro analyses performed in human cells showed that the frequency of peripheral blood Th1 and Th17 cells, two phenotypes favoured by DRD3-signalling, were significantly increa...

In this study, we used a monosynaptic rabies tracing technique to label the whole-brain inputs to specific cell types in the MOp and MOs simultaneously in a same transgenic mouse. First, 150 nl AAV helper mixtures were injected into the ipsilateral MOp (AP:1.54 mm, ML:1.70 mm, DV:-1.50 mm) and MOs (AP:1.54 mm, ML:0.50 mm, DV:-1.35 mm) in Thy1-cre or Vgat-cre mice respectively, mixed with rAAV2/9-Ef1α-DIO-BFP-2a-TVA-WPRE-pA and rAAV2/9-Ef1α-DIO-RG-WPRE-pA as the ratio of 1:2. Three weeks later, 300 nl RV-ΔG-EnVA-EGFP and RV-ΔG-EnVA-Dsred were injected into the two subregions of the MC respectively. O...
