Neutrophil Extracellular Traps Exacerbate Ischemic Brain Damage
AbstractMost acute strokes are ischemic, and subsequent neuroinflammation promotes further damage leading to cell death but also plays a beneficial role by promoting cellular repair. Neutrophils are forerunners to brain lesions after ischemic stroke and exert elaborate functions. While neutrophil extracellular traps (NETs) possess a fundamental antimicrobial function within the innate immune system under physiological circumstances, increasing evidence indicates that NETosis, the release process of NETs, occurs in the pathogenic process of stroke. In this review, we focus on the processes of NET formation and clearance, th...

Ferrostatin-1 Alleviates White Matter Injury Via Decreasing Ferroptosis Following Spinal Cord Injury
AbstractSpinal cord injury (SCI), a devastating neurological impairment, usually imposes a long-term psychological stress and high socioeconomic burden for the sufferers and their family. Recent researchers have paid arousing attention to white matter injury and the underlying mechanism following SCI. Ferroptosis has been revealed to be associated with diverse diseases including stroke, cancer, and kidney degeneration. Ferrostatin-1, a potent inhibitor of ferroptosis, has been illustrated to curb ferroptosis in neurons, subsequently improving functional recovery after traumatic brain injury (TBI) and SCI. However, the role...

Development of Molecular Magnetic Resonance Imaging Tools for Risk Stratification of Carotid Atherosclerotic Disease Using Dual-Targeted Microparticles of Iron Oxide
AbstractIdentification of patients with high-risk asymptomatic carotid plaques remains a challenging but crucial step in stroke prevention. Inflammation is the key factor that drives plaque instability. Currently, there is no imaging tool in routine clinical practice to assess the inflammatory status within atherosclerotic plaques. We have developed a molecular magnetic resonance imaging (MRI) tool to quantitatively report the inflammatory activity in atherosclerosis using dual-targeted microparticles of iron oxide (DT-MPIO) against P-selectin and VCAM-1 as a smart MRI probe. A periarterial cuff was used to generate plaque...

Arterial Ischemic Stroke —Peculiarities of Clinical Presentation and Risk Factors in Indian Children
Neuropediatrics DOI: 10.1055/s-0041-1728773There are not enough recent studies on arterial ischemic stroke (AIS) in Indian children. We retrospectively reviewed data on 95 children (69 boys), aged 3 months to 17 years, with AIS. Focal signs were noted in 84 (88%) with hemiparesis in 72 (76%). Diffuse signs were present in 33 (35%) with fever in 22 (23%), altered mental status in 20 (21%), and headache in 12 (13%). Seizures occurred in 29 (31%) children. Arteriopathy was observed in 57 (60%) children with mineralizing lenticulostriate vasculopathy (mLSV) in 22 (23%) being the most common, followed by moyamoya in 14 (15%), a...

Selective hand motor cortex lesions masquerading as & #8220;Pseudoperipheral Nerve Palsy & #8221;
Bhaskara P Shelley, Prakash Harishchandra, Acharya K DevadasAnnals of Indian Academy of Neurology 2020 23(5):688-693 Strategic cortical lesions involving the hand motor cortex (HMC) presenting acutely as distal upper limb pure motor weakness certainly do need to be differentiated on clinical grounds from “pseudoperipheral palsy.” This rare phenotype can imitate peripheral motor nerve deficits and should not be easily overlooked. The? isolated “central hand and finger weakness” presenting as an acute onset of varying combinations such as pseudomedian, pseudoradial,...

Effects of Antimalarial Drugs on Neuroinflammation-Potential Use for Treatment of COVID-19-Related Neurologic Complications
AbstractThe SARS-CoV-2 virus that is the cause of coronavirus disease 2019 (COVID-19) affects not only peripheral organs such as the lungs and blood vessels, but also the central nervous system (CNS) —as seen by effects on smell, taste, seizures, stroke, neuropathological findings and possibly, loss of control of respiration resulting in silent hypoxemia. COVID-19 induces an inflammatory response and, in severe cases, a cytokine storm that can damage the CNS. Antimalarials have unique properti es that distinguish them from other anti-inflammatory drugs. (A) They are very lipophilic, which enhances their ability to cross ...

Iron Measured in Nasal Exudate Samples as a New and Useful Biomarker in the Differential Diagnosis of Patients with Acute Stroke
Conclusions: Our findings suggest that iron levels in nasal exudate may be useful in the acute stage for the differential diagnosis between ischemic and hemorrhagic damage in acute stroke patients. They also open a potential field to study other biomarkers in nasal exudate in several neurological disorders. Clinical studies must be performed to confirm our results.Cerebrovasc Dis

Epigenetic regulators of neuronal ferroptosis identify novel therapeutics for neurological diseases: HDACs, transglutaminases, and HIF prolyl hydroxylases.
Abstract A major thrust of our laboratory has been to identify how physiological stress is transduced into transcriptional responses that feed back to overcome the inciting stress or its consequences, thereby fostering survival and repair. To this end, we have adopted the use of an in vitro model of ferroptosis, a caspase-independent, but iron-dependent form of cell death (Dixon et al., 2012; Ratan, 2020). In this review, we highlight three distinct epigenetic targets that have evolved from our studies and which have been validated in vivo studies. In the first section, we discuss our studies of broad, pan-selecti...

Therapeutic Effects of Iron Chelation in Atorvastatin-Induced Intracranial Hemorrhage of Zebrafish Larvae
Intracranial hemorrhage (ICH) acutely and severely damages brain function.1,2 The prognosis of ICH is poor due to the drastic and rapid progression of its pathology, and the lack of effective treatments presents a significant unmet clinical need. Therefore, novel therapeutic agents for ICH have the potential to significantly improve clinical outcomes. The collagenase-induced rodent ICH model is the most commonly used experimental ICH model.3 However, detailed live imaging of hematoma development in rodent models is inherently limited, as rodents are opaque.

Brainstem iron overload and injury in a rat model of brainstem hemorrhage
Brainstem hemorrhage (BSH) is the most devastating subtype of intracerebral hemorrhage (ICH) with the highest mortality ranging from 56 % to 61.2 %. However, there is no effective medical or surgical therapy to improve its outcomes in clinic to date due to lack of understanding of its injury mechanisms. Herein, we explored the brainstem iron overload and injury in a rat model of BSH.

Association between aluminum in drinking water and incident Alzheimer's disease in the Canadian Study of Health and Aging cohort.
Abstract Epidemiological evidence linking aluminum in drinking water and Alzheimer's disease (AD) has been inconsistent, with previous studies often limited by small sample sizes. The present study addresses this issue using data from the Canadian Study of Health and Aging (CSHA), a prospective cohort of 10,263 subjects followed-up from 1991-1992 through 2001-2002. Participants' residential histories were linked to municipal drinking water sources in 35 Canadian municipalities to obtain ecologic pH, aluminum, fluoride, iron and silica concentrations in drinking water. Cox proportional hazards models were used to e...
