Association Between the Change of Serum Copper and Ischemic Stroke: a Systematic Review and Meta-Analysis
AbstractIschemic stroke is the most common stroke subtypes with all strokes. More and more studies found that serum copper was related to the ischemic stroke. However, the correlation between serum copper and ischemic stroke was inconsistent. We performed the meta-analysis to assess the association between the change of serum copper and ischemic stroke. Electronic databases were identified to search for relevant studies about serum copper and ischemic stroke from inception to February 28, 2019. Eight studies with a total of 777 participants were included into this meta-analysis. Because of high heterogeneity (I2 = 71%), we...

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 ...

Differential associations of particle size ranges and constituents with stroke emergency-room visits in Shanghai, China
CONCLUSION: Ultra-fine particles and some PM2.5 constituents (i.e., carbonaceous fractions, inorganic ions and some elements) may be mainly responsible for the excess risk of stroke induced by PM2.5.PMID:35104777 | DOI:10.1016/j.ecoenv.2022.113237

Environmental toxic metal contaminants and risk of stroke: a systematic review and meta-analysis
Environ Sci Pollut Res Int. 2022 Feb 22. doi: 10.1007/s11356-022-18866-z. Online ahead of print.ABSTRACTThe relationship between toxic metals in the environment and clinical stroke risk remains unclear, although their role as immunotoxicants and carcinogens has been well established. We conducted a systematic review of the relationship between five metals (arsenic, mercury, copper, cadmium, and lead) and stroke. First, we comprehensively searched 3 databases (Pubmed, EMBASE, and Cochrane) from inception until June 2021. Random-effects meta-analyses, pooled relative risks (RR) and 95% confidence intervals (CI) were applied ...

Association Between Serum Copper and Stroke Risk Factors in Adults: Evidence from the National Health and Nutrition Examination Survey, 2011-2016
This study aimed to examine the relationships between serum copper and lipid levels among 3425 participants aged 20 years and older from the 2011-2016 National Health and Nutrition Examination Survey (NHANES). Data on administered questionnaires, serum copper concentrations, and lipid levels (total cholesterol, HDL cholesterol, triglycerides, and LDL cholesterol) were used. Associations between serum copper and lipid levels were evaluated using both multivariable linear regression and logistic regression models. In the linear regression models, total cholesterol and LDL cholesterol levels increased with increasing copper c...

Associations of multiple plasma metals with the risk of ischemic stroke: A case-control study.
CONCLUSIONS: Our study suggested that higher plasma concentrations of aluminum, arsenic, and cadmium, and lower concentrations of iron and selenium may increase the risk of IS. Further prospective studies in larger populations are warranted to confirm our findings. PMID: 30716572 [PubMed - as supplied by publisher]

The Copper bi s(thiosemicarbazone) Complex Cu II (atsm) Is Protective Against Cerebral Ischemia Through Modulation of the Inflammatory Milieu
This study was undertaken to assess whether the copperbis(thiosemicarbazone) complex, CuII(atsm), is beneficial in acute brain injury, in preclinical mouse models of ischemic stroke. We demonstrate that the copper complex CuII(atsm) protects neurons from excitotoxicity and N2a cells from OGDin vitro, and is protective in permanent and transient ischemia models in mice as measured by functional outcome and lesion size. Copper delivery in the ischemic brains modulates the inflammatory response, specifically affecting the myeloid cells. It reduces CD45 and Iba1 immunoreactivity, and alters the morphology of Iba1 positive cell...

Mortality and Morbidity Effects of Long-Term Exposure to Low-Level PM 2.5 , BC, NO 2 , and O 3 : An Analysis of European Cohorts in the ELAPSE Project
CONCLUSIONS: Long-term exposure to PM2.5, NO2, and BC was positively associated with natural-cause and cause-specific mortality in the pooled cohort and the administrative cohorts. Associations were found well below current limit values and guidelines for PM2.5 and NO2. Associations tended to be supralinear, with steeper slopes at low exposures with no indication of a threshold. Two-pollutant models documented the importance of characterizing the ambient mixture with both NO2 and PM2.5. We mostly found negative associations with O3. In two-pollutant models with NO2, the negative associations with O3 were attenuated to esse...

Peripheral Vascular Disease and Carotid Artery Disease Are Associated with Decreased Bile Acid Excretion
This study investigated BAE in patients with peripheral vascular disease (PVD) and carotid artery disease (CA) and those without these diseases, compared to patients with CAD, stroke, or no evidence of atherosclerosis. Patients with complaints of chest pain-suspected CAD, syncope, stroke/TIA, severe headache, intermittent claudication, or falls were enrolled. All received a 4-day standard diet with 490 mg of cholesterol and internal standard copper thiocyanate. Fecal BAE was measured using gas-liquid chromatography. One hundred and three patients, sixty-eight (66%) men and thirty-five women (34%), mean age range 60.9 ± 8....

Benefits of Motor Imagery for Human Space Flight: A Brief Review of Current Knowledge and Future Applications
Conclusion: How to Implement MI Into the Preparation and Mission of the Astronauts Motor imagery should ideally be performed before, during, and after exposure to microgravity to prepare for the lack of gravity, counteract the effects of weightlessness and promote the re-adaptation to normogravity. A quite similar theoretical viewpoint had been nicely proposed by Bock et al. (2015), who more specifically focused on the preparation period few days before landing. These authors developed two phases of individual MI training program to reach an optimal level of preparation before exposure to microgravity. In the first phase,...
