Recently, it has been suggested that central and peripheral toxicities identified in persons with substance use disorder (SUD) could be partially associated with an imbalance in reactive oxygen species and antioxidant defenses. We conducted a systematic review and meta-analysis to investigate whether SUD is associated with oxidative stress and to identify biomarkers possibly more affected by this condition. We have included studies that analysed oxidant and antioxidant markers in individuals with SUD caused by stimulants, alcohol, nicotine, opioids, and others (cannabis, inhalants, and polysubstance use). Our analysis showed that persons with SUD show higher oxidant markers and lower antioxidant markers …

The human brain and central nervous system (CNS) harbor a select sub‐group of potentially pathogenic microRNAs (miRNAs), including a well‐characterized NF‐kB‐sensitive Homo sapiens microRNA hsa‐miRNA‐146a‐5p (miRNA‐146a). miRNA‐146a is significantly over-expressed in progressive and often lethal viral‐ and prion‐mediated and related neurological syndromes associated with progressive inflammatory neurodegeneration. These include ~18 different viral‐induced encephalopathies for which data are available, at least ~10 known prion diseases (PrD) of animals and humans, Alzheimer’s disease (AD) and other sporadic and progressive age‐related neurological disorders. Despite the apparent lack of nucleic acids in prions, both DNA‐ and RNA‐containing viruses along with prions significantly induce miRNA‐146a …

Alzheimer’s disease (AD) is a multifactorial, age-related neurological disease characterized by complex pathophysiological dynamics taking place at multiple biological levels, including molecular, genetic, epigenetic, cellular and large-scale brain networks. These alterations account for multiple pathophysiological mechanisms such as brain protein accumulation, neuroinflammatory/neuro-immune processes, synaptic dysfunction, and neurodegeneration that eventually lead to cognitive and behavioral decline. Alterations in microRNA (miRNA) signaling have been implicated in the epigenetics and molecular genetics of all neurobiological processes associated with AD pathophysiology. These changes encompass altered miRNA abundance, speciation and complexity in anatomical regions of the CNS targeted by the disease, including modified miRNA expression …
