Mediterranean-style diet and intracranial large artery stenosis in the Northern Manhattan Study
Intracranial large artery stenosis (ICAS) is one of the most common causes of stroke worldwide.1 Among stroke-free community-dwelling adults, ICAS is prevalent, associated with modifiable vascular risk factors, and confers risk of incident vascular events.2 Given prior work linking a Mediterranean-style diet (MeDi), which is rich in fruits, vegetables, fish, whole grains, legumes, and nuts, to reduced risk of vascular conditions and cardiovascular events,3,4 we hypothesized MeDi may also be protective against ICAS.

Up-regulation of lncRNA NEAT1 in cerebral ischemic stroke promotes activation of astrocytes by modulation of miR-488-3p/RAC1
Exp Brain Res. 2022 Dec 23. doi: 10.1007/s00221-022-06519-z. Online ahead of print.ABSTRACTWe aim to research the molecular mechanism of lncRNA NEAT1 in the activation of astrocytes in a cerebral ischemia-reperfusion injury model. Mouse model of cerebral ischemia-reperfusion injury was constructed, and shNEAT1 was transfected. The infarct area, brain water content, and neurological deficiency were detected. Immunofluorescence detection and fluorescence in situ hybridization (FISH) assay were processed to detect glial fibrillary acidic protein (GFAP) expression. Astrocyte cells were cultured for oxygen-glucose deprivation/r...

Long Non-coding RNA PVT1 Inhibits miR-30c-5p to Upregulate Rock2 to Modulate Cerebral Ischemia/Reperfusion Injury Through MAPK Signaling Pathway Activation
AbstractLong non-coding RNAs (lncRNAs) play a key role in a variety of disease processes. Plasmacytoma variant translocation 1 (PVT1), a lncRNA, is known to regulate cell functions and play a key role in the pathogenesis of many malignant tumors. The function and molecular mechanisms of lncRNA-PVT1 in cerebral ischemia remain unknown. Real-time PCR (qRT-PCR) was used to detect lncRNA-PVT1 and microRNA-30c-5p (miR-30c-5p) expression in the brain tissues of mice underwent middle cerebral artery occlusion/reperfusion (MCAO/R) and oxygen –glucose deprivation/reperfusion (OGD/R)-treated mouse primary brain neurons.

Dietary Oily Fish Intake is Inversely Associated with Severity of White Matter Hyperintensities of Presumed Vascular Origin. A Population-Based Study in Frequent Fish Consumers of Amerindian Ancestry
Oily fish is a major dietary source of omega-3 polyunsaturated fatty acids and other nutrients that may reduce the expression of cerebral small vessel disease (cSVD) biomarkers, including white matter hyperintensities (WMH) of presumed vascular origin. However, information on this relationship is limited. We aimed to assess the association between oily fish intake and WMH severity in a population of frequent fish consumers.

Diet and Lifestyle as Risk Factors for Carotid Artery Disease: A Prospective Cohort Study
Conclusions: In conclusion, the present study found a trend toward a protective effect of higher intake of vegetables and fruit against incident CAD. More prospective studies investigating the association between diet and CAD and stroke are needed in order to give firm recommendations.Cerebrovasc Dis

Mediterranean diet: The role of long-chain ω-3 fatty acids in fish; polyphenols in fruits, vegetables, cereals, coffee, tea, cacao and wine; probiotics and vitamins in prevention of stroke, age-related cognitive decline, and Alzheimer disease.
Authors: Román GC, Jackson RE, Gadhia R, Román AN, Reis J Abstract The mechanisms of action of the dietary components of the Mediterranean diet are reviewed in prevention of cardiovascular disease, stroke, age-associated cognitive decline and Alzheimer disease. A companion article provides a comprehensive review of extra-virgin olive oil. The benefits of consumption of long-chain ω-3 fatty acids are described. Fresh fish provides eicosapentaenoic acid while α-linolenic acid is found in canola and soybean oils, purslane and nuts. These ω-3 fatty acids interact metabolically with ω-6 fatty acids mainly linoleic...

Fish Consumption and Stroke Risk: A Meta-Analysis of Prospective Cohort Studies
Inconsistent results of the association between fish consumption and stroke risk have been indicated in previous epidemiological studies. Therefore, we performed a meta-analysis of prospective cohort studies to estimate the impact of fish consumption on stroke risk.

Post-stroke administration of omega-3 polyunsaturated fatty acids promotes neurovascular restoration after ischemic stroke in mice: Efficacy declines with aging.
Abstract Post-stroke treatment with omega-3 polyunsaturated fatty acids (n-3 PUFAs) may be a promising therapy in young animals but this has not been tested in aged subjects, a population at most risk of ischemic stroke. Herein we examined the therapeutic efficacy of n-3 PUFAs after distal middle cerebral artery occlusion (dMCAO) in young (10-12 weeks old) and aged (18 months old) mice. Post-ischemic mice were randomly assigned to 4 groups that received: 1) regular food with low content of n-3 PUFAs, 2) intraperitoneal docosahexaenoic acid (DHA, a major component of n-3 PUFAs) injections, 3) Fish oil (FO, cont...
