Parkinson’s disease: the nutrition perspective

Parkinson‟s disease (PD) is the second most common neurodegenerative disease after Alzheimer‟sdisease and affects ~1% of the population over the age of 60 years in industrialised countries. Theaim of this review is to examine nutrition in PD across three domains: dietary intake and thedevelopment of PD; whole body metabolism in PD; and the effects of […]

Highly efficient intercellular spreading of protein misfolding mediated by viral ligand-receptor interactions

Thoughts – Just maybe we are finding the mechanics behind the 2+ theory of PD which states that 2 or more variables must come about in order PD to progress into diagnosisable PD. Protein aggregates associated with neurodegenerative diseases have the ability to transmit to unaffected cells, thereby templating their own aberrant conformation onto soluble

The pathogenic mechanism of oral bacteria and treatment with inhibitors

Objectives: The objective of this study was to introduce the evidence obtained throughextensive research that periodontitis increases risk of many systemic diseases. Method: Analysis of some oral bacteria (P. gingivalis, T. denticola, T. forsythia, A.actinomycetemcomitans, and F. nucleatum) and its related treatments and mediatorsby the specific methods (western blot, ELISA, etc). Results: This article reviews

Overcoming epistemic injustices in the biomedical study of ayahuasca. Towards ethical and sustainable regulation

After decades of biomedical research on ayahuasca’s molecular compounds and theirphysiological effects, recent clinical trials show evidence of therapeutic potential for depression.However, indigenous peoples have been using ayahuasca therapeutically for a very longtime, and thus we question the epistemic authority attributed to scientific studies, proposing thatepistemic injustices were committed with practical, cultural, social and legal

A novel multi-target strategy to attenuate the progression of Parkinson’s disease by diamine hybrid AGE/ALE inhibitor

Instead of a conventional ‘one-drug-one-target approach’, this article presents a novel multi-target approach with a concept of trapping simultaneously as many detrimental factors as possible involved in the progression of Parkinson’s disease. These factors include reactive carbonyl species, reactive oxygen species, Fe3+/Cu2+ and ortho-quinones (o-quinone), in particular. Different from the known multi-target strategies for Parkinson’s disease,

Genome-wide association study of REM sleep behavior disorder identifies novel loci with distinct polygenic and brain expression effects

Rapid eye movement (REM) sleep behavior disorder (RBD), enactment of dreams during REM sleep, isan early clinical symptom of alpha-synucleinopathies. RBD also defines more severe forms of alphasynucleinopathies. The genetic background of RBD and its underlying mechanisms are not wellunderstood. Here, we performed the first genome-wide association study of RBD, identifying five RBD riskloci. Expression

Circulatory 25(OH)D and 1,25(OH)2D as differential biomarkers between multiple system atrophy and Parkinson’s disease patients

There is sufficient evidence to support vitamin D’s noncalcemic effects and the role ofvitamin D deficiency in the development of a wide range of neurological disorders. This study aimed to evaluatewhether serum 25(OH)D and 1,25(OH) 2 D could be used as biomarkers to differentiate between healthy subjects(HS), multiple system atrophy (MSA) and Parkinson’s disease (PD)

Mild Parkinsonian Signs: A Systematic Review of Clinical, Imaging, and Pathological Associations

There are currently no consistent radiological findings for MPS, and pathological studies have shown that MPS, at least in the oldest old, are often underpinned by mixed neuropathologies, including those associated with Alzheimer’s disease, cerebrovascular disease, nigral neuronal loss, and Lewy bodies. Different subcategories of MPS appear to convey varying risk and specificity for PD

Mitochondrial Dysfunction in a Mouse Model of Prodromal Parkinson’s Disease: A Metabolomic Analysis

For the development of disease-modifying therapies for Parkinson’s disease (PD) the identification of biomarkers in the prodromal stage is urgently required. Because PD is considered a systemic disease even in the early stage, we performed a metabolomic analysis of the plasma from a mouse model of prodromal PD (p-PD). Increased levels of isobutyrylcarnitine in p-PD

Calcium channels and iron metabolism: A redox catastrophe in Parkinson’s disease and an innovative path to novel therapies?

Autonomously spiking dopaminergic neurons of the substantia nigra pars compacta (SNpc) are exquisitely specialized and suffer toxic iron-loading in Parkinson’s disease (PD). However, the molecular mechanism involved remains unclear and critical to decipher for designing new PD therapeutics. The long-lasting (L-type) CaV1.3 voltage-gated calcium channel is expressed at high levels amongst nigral neurons of the
