In silico identification of molecular mechanisms for stroke risk caused by heavy metals and their mixtures: sponges and drugs involved
This study used various approaches and databases to evaluate the molecular processes and identify miRNA sponges and drugs associated with the development of stroke caused by heavy metals and their combinations. We found that the genes ALB (albumin), IL1B (Interleukin-1β), F2 (coagulation factor II), APOA1 (apolipoprotein A1), IL6 (Interleukin 6), and NOS2 (nitric oxide synthase 2) were linked to the development of strokes by 18 chemicals and a combination of cadmium, copper, and lead. These results may point to the significance of detoxification and neuroinflammation in stroke as well as the potential for targeting these ...

Evident lower blood levels of multiple nutritional compounds and highly prevalent malnutrition in sub-acute stroke patients with or without dysphagia
This study shows that malnutrition is highly prevalent in sub-acute stroke patients during rehabilitation. Even though patients with OD were more likely to be malnourished, blood levels of specific nutritional compounds were similarly lower in stroke patients with or without OD compared to healthy reference subjects. Furthermore, subgroup analysis showed similarly lower blood levels of specific nutritional compounds in patients that are normal nourished vs. patients with (risk of) malnutrition. This might imply disease-specific changes in blood levels on top of overall protein-energy malnutrition. The results of the curren...

Is Selenium Supplementation Beneficial in Acute Ischemic Stroke?
This study proposed to investigate the effect of intravenous Se (Selenase) administration in patients with acute ischemic stroke (AIS) on neurological outcomes, antioxidant enzyme activity, and inflammatory marker levels. Methods: AIS patients (n=50) were recruited from a neurology unit of a university-affiliated hospital. Patients were randomly assigned to receive either Selenase or placebo (saline) for 5 days. The modified ranking scale, the national institute of health stroke scale, and the mini-mental state examination, as primary outcomes, and the serum GPx concentration, total antioxidant activity, and tumor n...

Evaluation of Selenium Supplementation in Acute Ischemic Stroke Outcome: An Outcome Assessor Blind, Randomized, Placebo-Controlled, Feasibility Study
Conclusions: Selenium selenite supplementation in acute ischemic stroke can improve short-term outcome but cannot influence the long-term outcome.

Characterization of Selenium Compounds for Anti-ferroptotic Activity in Neuronal Cells and After Cerebral Ischemia –Reperfusion Injury
AbstractThe emergence of ferroptosis as a cell death pathway associated with brain disorders including stroke and neurodegenerative diseases emphasizes the need to develop therapeutics able to target the brain and to protect neurons from ferroptotic death. Selenium plays an essential role in reducing lipid peroxidation generated during ferroptosis through its incorporation into the catalytic site of glutathione peroxidase 4. Here, we compared the anti-ferroptotic activity of several organic and inorganic selenium compounds: methylselenocysteine, selenocystine, selenomethionine, selenocystamine, ebselen, sodium selenite, an...
