Arsenic, polycyclic aromatic hydrocarbons, and metal exposure and risk assessment of stroke
This study aimed to assess different arsenic species, including total arsenic; two types of organic arsenic, i.e., arsenobetaine and arsenocholine; four types of inorganic arsenic, i.e., arsenic acid, arsenous acid, dimethylarsinic acid (DMA), and monomethylarsonic acid (MMA); six types of urinary polycyclic aromatic hydrocarbon (PAH) compounds, i.e., 1-hydroxynaphthalene, 1-hydroxyphenanthrene, 1-hydroxypyrene, 2-hydroxynaphthalene, 2-hydroxyfluorene, and 3-hydroxyfluorene; and fourteen types of metals from urine specimen, i.e., manganese, cadmium, lead, mercury, barium, cobalt, strontium, molybdenum, cesium, thallium, an...

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]

Neuroprotective Effects of a Cardioplegic Combination (Adenosine, Lidocaine, and Magnesium) in an Ischemic Stroke Model
We examined the effects of low-dose ALM on ischemic stroke in cell and animal models. Cobalt chloride (CoCl2) –treated SH-SY5Y cells were used as a surrogate model to mimic oxygen–glucose deprivation conditions. The cells were incubated with different dilutions of ALM authentic solution (1.0 mM adenosine, 2.0 mM lidocaine, and5 mM MgSO4 in Earle’s balanced salt solution). At a concentration of 2.5%, ALM significantly reduced CoCl2-induced cell loss. This protective effect persisted even when ALM was administered 1  h after the insult. We used transient middle cerebral artery occlusion to investigate the therapeuti...

One-year outcome of a prospective trial stopping dual antiplatelet therapy at 3 months after everolimus-eluting cobalt-chromium stent implantation: ShortT and OPtimal duration of Dual AntiPlatelet Therapy after everolimus-eluting cobalt-chromium stent (STOPDAPT) trial
In conclusion, stopping DAPT at 3 months in selected patients after CoCr-EES implantation was at least as safe as the prolonged DAPT regimen adopted in the historical control group.

Plasma Metal Concentrations and Incident Coronary Heart Disease in Chinese Adults: The Dongfeng-Tongji Cohort
Conclusions: Our study suggested that incident CHD was positively associated with plasma levels of titanium and arsenic, and inversely associated with selenium. Additional research is needed to confirm these findings in other populations. https://doi.org/10.1289/EHP1521 Received: 22 December 2016 Revised: 17 September 2017 Accepted: 19 September 2017 Published: 19 October 2017 Address correspondence to T.

mfat ‐1 transgene protects cultured adult neural stem cells against cobalt chloride‐mediated hypoxic injury by activating Nrf2/ARE pathways
Abstract Ischemic stroke is a devastating neurological disorder and one of the leading causes of death and serious disability in adults. Adult neural stem cell (NSC) replacement therapy is a promising treatment for both structural and functional neurological recovery. However, for the treatment to work, adult NSCs must be protected against hypoxic‐ischemic damage in the ischemic penumbra. In the present study, we aimed to investigate the neuroprotective effects of the mfat‐1 transgene on cobalt chloride (CoCl2)‐induced hypoxic‐ischemic injury in cultured adult NSCs as well as its underlying mechanisms. The results ...

Endothelin-1 (ET-1) Promotes a Proinflammatory Microglia Phenotype in Diabetic Conditions.
Abstract Diabetes increases the risk and severity of cognitive impairment, especially after ischemic stroke. It is also known that the activation of ET system is associated with cognitive impairment and microglia around periinfarct area produce ET-1. However, little is known about the effect of ET-1 on microglial polarization, especially under diabetic conditions. We hypothesized that a) ET-1 activates microglia to proinflammatory M-1 like phenotype, and b) Hypoxia/LPS activates the microglial ET system and promotes microglial activation towards M-1 phenotype in diabetic conditions. Microglial cells (C8B4) culture...

B355252, A Novel Small Molecule, Confers Neuroprotection Against Cobalt Chloride Toxicity In Mouse Hippocampal Cells Through Altering Mitochondrial Dynamics And Limiting Autophagy Induction.
Authors: Chimeh U, Zimmerman MA, Gilyazova N, Li PA Abstract Cerebral hypoxia as often occurs in cases of stroke, hemorrhage, or other traumatic brain injuries, is one of the leading causes of death worldwide and a main driver of disabilities in the elderly. Using a chemical mimetic of hypoxia, cobalt chloride (CoCl2), we tested the ability of a novel small molecule, 4-chloro-N-(naphthalen-1-ylmethyl)-5-(3-(piperazin-1-yl)phenoxy)thiophene-2-sulfonamide (B355252), to alleviate CoCl2-induced damage in mouse hippocampal HT22 cells. A dose-dependent decrease in cell viability was observed during CoCl2 treatment along ...
