Alpha-synuclein interaction with mitochondria is the final mechanism of ferroptotic death induced by erastin in SH-SY5Y cells.

Ferroptosis has been characterized as a form of iron-dependent regulated cell death accompanied by an accumulation of reactive oxygen species and lipid oxidation products along with typical morphological alterations in mitochondria. Ferroptosis is activated by diverse triggers and inhibited by ferrostatin-1 and liproxstatin-1, apart from iron chelators and several antioxidants, and the process is implicated in multiple pathological conditions. There are, however, certain ambiguities about ferroptosis, especially regarding the final executioner of cell death subsequent to the accumulation of ROS.

Exosomal Dynamics and Brain Redox Imbalance: Implications in Alzheimer's Disease Pathology and Diagnosis.

Oxidative burden plays a central role in Alzheimer's disease (AD) pathology, fostering protein aggregation, inflammation, mitochondrial impairment, and cellular dysfunction that collectively lead to neuronal injury. The role of exosomes in propagating the pathology of neurodegenerative diseases including AD is now well established. However, recent studies have also shown that exosomes are crucial responders to oxidative stress in different tissues.

Assessing risk of bias in the meta-analysis of round 1 of the Health Care Innovation Awards.

Background: Systematic reviews of observational studies can be affected by biases that lead to under- or over-estimates of true intervention effects. Several tools have been reported in the literature that attempt to characterize potential bias. Our objective in this study was to determine the extent to which study-specific bias may have influenced intervention impacts on total costs of care (TCOC) in round 1 of the Health Care Innovation Awards.

Enhancing Anti-cancer Activity: Green Synthesis and Cytotoxicity Evaluation of Turmeric-Gold Nanocapsules on A549 Lung Cancer Cells.

Background Lung cancer remains a major global health concern, with a notable increase in new cases in recent years. This study aims to investigate the cytotoxic effects of polymeric turmeric-gold nanocapsules on A549 human lung cancer cells, utilizing green-synthesized gold nanoparticles from . and ethyl cellulose-based nanocapsules.

Meta-Analysis of the Impact of Four Advanced Primary Care Redesign Initiatives on Medicare Expenditures.

We conducted a secondary analysis of the evaluations of 22 sites participating in four primary care redesign initiatives funded by the Centers for Medicare and Medicaid Services or the Center for Medicare and Medicaid Innovation. Our objectives were to determine the overall impact of the initiatives on Medicare expenditures and whether specific site-level program features influenced expenditure findings. Averaged over sites, the mean intervention effect was a statistically insignificant US$26 per beneficiary per year.
