Summary: The use of cocaine without heroin declined overall from 2002 to 2017, but showed an increasing trend from 2011. In contrast, the co-use of heroin and cocaine, as well as heroin use without cocaine, showed a linear increase during the same period. It is important for screening, outreach, clinical treatment, and first responders to be aware of the increasing trends in polysubstance use and the potential impact of co-use of heroin and cocaine on intervention and overdose outcomes in the US.

Summary: Recent research has shown that Parkinson's disease (PD) patients have low serum levels of vitamins B12 and D. In this study, the effects of supplementation with both vitamins B12 and D on PD female mice and their fetuses were investigated. The results suggest that co-administration of vitamins B12 and D improves viability and reduces apoptosis and necrosis of cerebellar neurons in PD mice and their fetuses. These findings indicate that vitamins B12 and D have neuroprotective effects in PD, and they are recommended for supplementation during pregnancy in PD patients.

Summary: The absence of disease modifying drugs in Parkinson's disease therapy has led to the development of new chemical compounds targeting relevant biological targets. In this study, a small library of chromone derivatives was synthesized and screened to find potent inhibitors of monoamine oxidases, with modifications leading to compounds that showed desirable drug-like properties. Two specific compounds were identified as reversible, potent, selective, and non-cytotoxic MAO-B inhibitors, and displayed cytoprotective effects.

Summary: Targeting mitochondria with antioxidants is a promising strategy to prevent cellular senescence and skin ageing. This study investigates the potential use of mitochondria-targeted antioxidants (MitoBENs) as active ingredients to prevent senescence in skin cells. Among the tested compounds, the pyrogallol derivative MB2 showed the least toxicity and had a potent antioxidant protective effect against hydrogen peroxide cytotoxicity. It also decreased transcripts related to senescence in a 3D skin cell model. These findings suggest that MB2 could be a good candidate for further development as an active ingredient in skin anti-ageing products.

Summary: Ferroptosis is regulated cell death caused by oxidative perturbations controlled by Glutathione Peroxidase 4 (GPX4). It involves the increased production of reactive oxygen species, intracellular iron accumulation, lipid peroxidation, inhibition of system Xc-, glutathione depletion, and decreased GPX4 activity. In vitro and in vivo models have been used to study the pathophysiological mechanisms of neurodegenerative diseases involving ferroptosis. These models can also aid in the development of potential ferroptosis inhibitors for disease-modifying therapies. This review discusses the main in vitro and in vivo models used to evaluate ferroptosis and explore new drug targets and candidates.

Summary: Theragnostics is a promising strategy that combines diagnostics and therapeutics in a personalized manner. This review emphasizes the significance of redox homeostasis and mitochondrial function in personalized theragnostics. Disruption of redox homeostasis can lead to oxidative stress and cellular damage, which are associated with various diseases. Developing models of oxidative stress and mitochondrial dysfunction in metabolically conditioned cells allows for studying disease mechanisms and developing new therapies. By selecting appropriate cellular models, optimizing cell culture conditions, and validating the models, it is possible to identify the most promising therapeutic options and tailor treatments to individual patients. Overall, this review highlights the importance of precise and individualized approaches in theragnostics and the need for accurate in vitro models reflecting in vivo conditions.

Summary: Non-alcoholic fatty liver disease (NAFLD) is a global pandemic affecting 25% of the world's population and is a serious health and economic concern worldwide. NAFLD is mainly the result of unhealthy dietary habits combined with a sedentary lifestyle, although some genetic contributions to NAFLD have been documented. This review examines the role of mitochondrial dysfunction in the progression of NAFLD and suggests that targeting hepatocytes' mitochondrial physiology could be a potential therapy for this disease. However, further research is needed to explore the specific roles of different mitochondrial sub-populations and their communication with other subcellular organelles in NAFLD progression.

Summary: This study evaluates the efficacy of inhibiting or reducing histone deacetylases (HDACs) in Alzheimer's disease (AD) models by modifying gene transcription. The results show that inhibiting class I HDACs can ameliorate ER-mitochondria cross-talk in AD by normalizing calcium signaling between the two organelles. The selective HDAC inhibitor, Tacedinaline (Tac), counteracted the impaired ER-mitochondria communication and reduced amyloid beta levels in AD cells and animal models. These findings suggest that transcriptional regulation of ER-mitochondria communication could be a promising target for innovative therapeutics in AD.
