Ischemic stroke caused by giant cell arteritis associated with pulmonary adenocarcinoma
We describe a 77-year-old man with a sudden onset of dizziness, vomiting, and gait disturbances. Following imaging studies, a diagnosis of bulbar ischemic stroke with left vertebral artery stenosis was made. Based on a history of polymyalgia rheumatica, on laboratory tests, and brain digital subtraction angiography, a diagnosis of GCA was advanced and the patient underwent high-dose steroidal therapy. After a total body 18-FGD PET imaging, a pulmonary adenocarcinoma was found.Vertebral artery involvement is a rare but important occurrence in GCA as it carries a high mortality rate, and may require a vigorous therapeutic ap...

Polyoxometalate nanoclusters act as broad-spectrum antioxidants to alleviate ischemic stroke by intrathecal injection
Conclusion: Intrathecal injection significantly improved the delivery and efficacy of POM nanoclusters to the brain, resulting in the rapid accumulation of POM nanoclusters in the ischemic penumbra. Due to this, we confirmed that the POM nanoclusters could be used as nano-antioxidants to inhibit oxidative stress as well as inflammatory damage effectively.

Stroke-like migraine attacks after radiation therapy (SMART) syndrome —a case series and review
ConclusionOur extensive review favors MRI, CT, and prolonged EEG monitoring to rule out other differentials and showed that initiation of corticosteroid therapy and antiepileptic treatment were helpful in the resolution of symptoms and prevent recurrences. Therefore, future studies should be focused on early identification and management guidelines for SMART syndrome.

Lacunar stroke as a very late complication of radiotherapy: value of nuclear medicine techniques.
CONCLUSIONS: The reappearance of neurological symptoms years after radiotherapy of a brain neoplasm poses a diagnostic dilemma. Current diagnostic techniques are very accurate but present false positives. The various nuclear medicine techniques, in particular PET-CT 11C-methionine, are a diagnostic aid. With the presentation of this case we intend to draw attention to one of the late complications of radiation therapy and the various differential diagnoses. Diagnostic and therapeutic advances have increased the life expectancy of cancer patients, so these late complications are expected to be more frequent. PMID: 3331...

Effects of electroacupuncture on the functionality of NG2-expressing cells in perilesional brain tissue of mice following ischemic stroke
Neural Regen Res. 2022 Jul;17(7):1556-1565. doi: 10.4103/1673-5374.330611.ABSTRACTNeural/glial antigen 2 (NG2)-expressing cells has multipotent stem cell activity under cerebral ischemia. Our study examined the effects of electroacupuncture (EA) therapy (2 Hz, 1 or 3 mA, 20 minutes) at the Sishencong acupoint on motor function after ischemic insult in the brain by investigating the rehabilitative potential of NG2-derived cells in a mouse model of ischemic stroke. EA stimulation alleviated motor deficits caused by ischemic stroke, and 1 mA EA stimulation was more efficacious than 3 mA EA stimulation or positive control trea...

Inducible Prostaglandin E Synthase as a Pharmacological Target for Ischemic Stroke
In this study, blockade of mPGES-1 by our several novel compounds abolished the lipopolysaccharide (LPS)-induced PGE2 and pro-inflammatory cytokines interleukin 1 β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α) in mouse primary brain microglia. Inhibition of mPGES-1 also decreased PGE2 produced by neuronal cells under oxygen –glucose deprivation (OGD) stress. Among the five enzymes for PGE2 biosynthesis, mPGES-1 was the most induced one in cerebral ischemic lesions. Systemic treatment with our lead compound MPO-0063 (5 or 10  mg/kg, i.p.) in mice after transient middle cerebral artery occlusion (MCAO) improved ...

Chronic cerebral hypoperfusion and blood-brain barrier disruption in uninjured brain areas of rhesus monkeys subjected to transient ischemic stroke
J Cereb Blood Flow Metab. 2022 Feb 9:271678X221078065. doi: 10.1177/0271678X221078065. Online ahead of print.ABSTRACTBlood-brain barrier (BBB) disruption is a pivotal pathophysiological process in ischemic stroke. Although temporal changes in BBB permeability during the acute phase have been widely studied, little is known about the chronic phase of cerebrovascular changes that may have a large impact on the long-term outcome. Therefore, this study was aimed to measure cerebral vascular abnormalities using CT perfusion in nine rhesus monkeys subjected to transient middle cerebral artery occlusion (tMCAO) for ≥1 year (MCA...

Therapeutic efficacy of matrix metalloproteinase-12 suppression on neurological recovery after ischemic stroke: Optimal treatment timing and duration
The objectives of this study were to (1) determine the effect of MMP-12 suppression by shRNA-mediated gene silencing on neurological/functional recovery, (2) establish the optimal timing of MMP-12shRNA treatment that provides maximum therapeutic benefit, (3) compare the effectiveness of acute versus chronic MMP-12 suppression, and (4) evaluate potential sex-related differences in treatment outcomes. Young male and female Sprague-Dawley rats were subjected to transient middle cerebral artery occlusion and reperfusion. Cohorts of rats were administered either MMP-12shRNA or scrambled shRNA sequence (control) expressing plasm...

Diindolylmethane Ameliorates Ischemic Stroke-Induced Brain Injury by Peripheral and Central Mechanisms
CONCLUSION: This inhibition of platelet aggregation, platelet mediated oxidative stress, and inflammation, improved blood flow, and reduced neurological deficits, brain infarction, BBB leakage, brain water content, and histopathological abnormalities indicate the preservation of brain structural integrity. Therefore, these findings conclude that DIM exhibits neuroprotection by inhibiting platelet aggregation. Thus, the present study provided preclinical evidence of DIM neuroprotection against ischemic stroke.PMID:36397630 | DOI:10.2174/1567202620666221116161128
