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...

Phoenixin-20 ameliorates brain infarction by promoting microglia M2 polarization in an ischemic stroke model
In this study, we found that administration of Phoenixin-20 in ischemic stroke middle cerebral artery occlusion (MCAO) mice significantly reduced the brain infarction area but improved the neurological deficit score. Gene expression analysis showed Phoenixin-20 treatment inhibited pro-inflammatory M1 phase microglial markers: a cluster of differentiation molecule 11b (CD11b), cluster of differentiation molecule 86 (CD86), inducible nitric oxide synthase (iNOS), tumor necrosis factor-alpha (TNF- α), interleukin 6 (IL-6), and increased anti-inflammatory M2 phase markers (found in Inflammatory Zone 1 (FIZZ1), Arginase 1 (Arg...

β2-Microglobulin exacerbates neuroinflammation, brain damage, and cognitive impairment after stroke in rats
In this study, we established a rat model of focal cerebral ischemia by occlusion of the middle cerebral artery. We found that β2M levels in the cerebral spinal fluid, serum, and brain tissue were significantly increased in the acute period but gradually decreased during the recovery period. RNA interference was used to inhibit β2M expression in the acute period of cerebral stroke. Tissue staining with 2,3,5-triphenyltetrazolium chloride and evaluation of cognitive function using the Morris water maze test demonstrated that decreased β2M expression in the ischemic penumbra reduced infarct volume and alleviated cognitive...

α7 nicotinic acetylcholine receptor agonist improved brain injury and impaired glucose metabolism in a rat model of ischemic stroke
AbstractVagus nerve stimulation through the action of acetylcholine can modulate inflammatory responses and metabolism. α7 Nicotinic Acetylcholine Receptor (α7nAChR) is a key component in the biological functions of acetylcholine. To further explore the health benefits of vagus nerve stimulation, this study aimed to investigate whether α7nAChR agonists offer beneficial effects against poststroke inflammatory and m etabolic changes and to identify the underlying mechanisms in a rat model of stroke established by permanent cerebral ischemia. We found evidence showing that pretreatment with α7nAChR agonist, GTS-21, improv...

Cumulative Incidence of Thromboembolism and Prognostic Impact of Stroke in < em > BRAF < /em > V600E-mutant Non-small-cell Lung Cancer
CONCLUSION: A substantial proportion of patients with BRAF V600E-mutant lung cancer experienced thromboembolism during their disease course. CRS of undetermined source may predict a worse prognosis in this population.PMID:36697098 | DOI:10.21873/anticanres.16237

CXCR4 Antagonist AMD3100 Protects Blood-Brain Barrier Integrity and Reduces Inflammatory Response After Focal Ischemia in Mice Original Contributions
Conclusions— CXCR4 antagonist AMD3100 significantly suppressed inflammatory response and reduced blood–brain barrier disruption after MCAO. AMD3100 attenuated ischemia-induced acute inflammation by suppressing leukocyte migration and infiltration, in addition to reducing proinflammatory cytokine expression in the ischemic region.

Do severe headaches portend greater stroke risk following CRT for childhood brain tumor?
Children with brain tumors are more likely to survive, with survival rates improving consistently over several decades and well over 70% of patients now surviving 5 years from diagnosis.1 The vast majority of these children will become long-term survivors. As cure rates improve, a greater focus has been placed on enduring patient health after cancer treatment.

Successful Intra-arterial Thrombolysis in a Patient with an Intracranial Meningioma
We report a case of a 78-year-old man who was seen in our emergency department within 2 hours from sudden onset of aphasia, right-sided hemiplegia, hypoesthesia, and homonymous hemianopsia. The National Institutes of Health Stroke Scale (NIHSS) score at admission was 20. Intra-arterial thrombolysis was performed with administration of .3 mg/kg of alteplase combined with mechanical thrombectomy. At discharge, his NIHSS score was 1, and after 90 days, his modified Rankin score was 1. To our knowledge, this is the first report of intra-arterial thrombolysis in a patient with acute ischemic stroke with an intracranial tumor.

Posterior circulation ischemic stroke in childhood and neurofibromatosis type 2
We report the clinical and genetic findings and review the previous literature on vasculopathy reported in association with NF2, with a focus on the symptoms presenting at disease onset. For our case patient, an unpublished germline mutation resulting in frameshift (c.876_877insT) was identified on blood screening. We report our full multidisciplinary assessment with vascular angiography, volumetric MRI and audiometry. Vasculopathy is not currently included in the criteria traditionally used for diagnosis of NF2. We suggest that vascular stroke in childhood may be considered a presenting symptom for NF2.

Childhood Infections and Trauma as Risk Factors for Stroke
Abstract Stroke is as common as brain tumor in children. The etiology of childhood arterial ischemic stroke (AIS) appears to be multifactorial, resulting from the interaction between genetic predisposition and environmental triggers. The risk factors for AIS in children are markedly different from the atherosclerotic risk factors in adults. Trauma and infections have been identified as associations in previous studies and are exposures of particular interest because of their increased prevalence in the children. The aim of this review article is to provide an overview of the research studies that have addressed t...
