CONCLUSIONS: In this review, biological and chemical knowledge of melatonin, its experimental effects, and the clinical impact on patients with neurological disorders were described. According to all of the beneficial results obtained from experimental and clinical trials, melatonin may have a prophylactic and therapeutic effect on neurological diseases. Strong collaboration between neurologists and health service policy makers is needed to encourage use of melatonin in the patients suffering from neurological diseases. Melatonin may be the solution we have been looking for. PMID: 31718830 [PubMed - as supplied by publisher]

Parkinson disease (PD) is the second most prevalent neurodegenerative disorder, next only to Alzheimer disease. As the average age of the United States and European populations increases, physicians caring for the elderly will be confronted with an increasing number of PD patients.

This article presents the original descriptions of some recent physics mechanisms (based on the thermodynamic, kinetic, and quantum tunnel effects) providing stable 2H/1H isotope fractionation, leading to the accumulation of particular isotopic forms in intra- or intercellular space, including the molecular effects of deuterium interaction with 18O/17O/16O, 15N/14N, 13C/12C, and other stable biogenic isotopes. These effects were observed mainly at the organelle (mitochondria) and cell levels. A new hypothesis for heavy nonradioactive isotope fractionation in living systems via neutron effect realization is discussed. The c...

AbstractPurpose of ReviewWe summarize structural (s)MRI findings of gray matter (GM) atrophy related to cognitive impairment in Alzheimer ’s disease (AD) and Parkinson’s disease (PD) in light of new analytical approaches and recent longitudinal studies results.Recent FindingsThe hippocampus-to-cortex ratio seems to be the best sMRI biomarker to discriminate between various AD subtypes, following the spatial distribution of tau pathology, and predict rate of cognitive decline. PD is clinically far more variable than AD, with heterogeneous underlying brain pathology. Novel multivariate approaches have been used t...

In this study, it was found that acetaldehyde treatment induced excessive mitochondrial fragmentation, impaired mitochondrial function and caused cytotoxicity in cortical neurons and SH-SY5Y cells. Further analyses showed that acetaldehyde induced the phosphorylation of mitochondrial fission related protein dynamin-related protein 1 (Drp1) at Ser616 and promoted its translocation to mitochondria. The elevation of Drp1 phosphorylation was partly dependent on the reactive oxygen species (ROS)-mediated activation of c-Jun-N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK), as N-acetyl-l-cysteine (NAC) pre...

Abstract Tramadol is a synthetic analog of codeine used to treat pain of moderate to severe intensity and is reported to have neurotoxic potential. At therapeutic dose, tramadol does not cause major side effects in comparison to other opioid analgesics, and is useful for the management of neurological problems like anxiety and depression. Long term utilization of tramadol is associated with various neurological disorders like seizures, serotonin syndrome, Alzheimer's disease and Parkinson's disease. Tramadol produces seizures through inhibition of nitric oxide, serotonin reuptake and inhibitory effects on GABA rec...

Abstract Chronic neuroinflammation is a common feature of the pathogenic mechanisms involved in various neurodegenerative age-associated disorders, such as Alzheimer's disease, multiple sclerosis, Parkinson's disease, and dementia. In particular, persistent low-grade inflammation may disrupt the brain endothelial barrier and cause a significant increase of pro-inflammatory cytokines and immune cells into the cerebral tissue that, in turn, leads to microglia dysfunction and lose of neuroprotective properties. Nowadays, growing evidence highlights a strong association between persistent peripheral inflammation, as w...

Abstract Monocarboxylates cannot cross the blood-brain barrier freely to participate in brain energy metabolism. Specific monocarboxylate transporters (MCTs) are needed to cross cellular membranes. Monocarboxylate transporter 2 (MCT2) is a major monocarboxylate transporter encoded by the SLC16A7 gene. Recent studies reported that neurodegenerative diseases of the CNS, such as Alzheimer's disease (AD) and Parkinson's disease (PD), were related to energy metabolic impairment. MCT2 also plays an important role in energy metabolism in the CNS. To provide experimental evidence for future research on the role of MCT2 in...
