BACKGROUND: The left-sided atrial septal pouch (SP), a recently re-discovered anatomical structure within the human interatrial septum, has emerged as a possible source of thrombi formation and a trigger for atrial fibrillation, thereby potentially increasing the risk for ischemic stroke. In many studies, the swine interatrial septum has been used as model of the human heart. Also, possible new strategies and devices for management of the SPs may first be tested in this pig model. Therefore, in this study, we aimed to evaluate swine interatrial septum morphology and to compare it with the human analog, especially in the light of SP occurrence...

A routine of light or moderate alcohol consumption (≤1 drink/day for women and 1 to 2 drinks/day for men) were associated with a lower risk for all-cause mortality, coronary artery disease (CAD), type 2 diabetes mellitus (T2D), heart failure (HF), and stroke. Conversely, heavy drinking, (>4 drinks/day) is associated with an increased risk for death and cardiovascular (CV) disease (CVD). Excessive alcohol intake trails behind only smoking and obesity among the 3 leading causes of premature deaths in the United States (US)...

Central venous catheter (CVC) insertion is extensively utilized in Intensive Care Units for evaluation of hemodynamic status, administration of intravenous drugs, and for providing nutritional support in critically ill patients. Unfortunately, CVC use is associated with complications including lung injury, bleeding, infection, and thrombosis. We present a patient with an acute ischemic stroke from an inadvertently placed CVC into the right common carotid artery. A 57-year-old male presented to our institution for left hemiplegia and seizures 2 days after a CVC was placed...

Isoquercetin (Iso) has been found to have neuroprotective effects against cerebral ischemic stroke. However, the exact molecular mechanism underlying its neuroprotective ability remains unclear. In this study, we aimed to evaluate the neuroprotective effects of Iso in primary culture of rat hippocampal neurons exposed to oxygen and glucose deprivation and reperfusion (OGD/R) injury and in rats subjected to middle cerebral artery occlusion and reperfusion (MCAO/R) injury. We found that rats treated with Iso exhibited a lower degree of infarct volume, and brain water content than the vehicle-treated rats...

BACKGROUND AND AIMS: Matrix metalloproteinase (MMP)-8 and myeloperoxidase (MPO) may contribute to cerebral damage in acute ischemic stroke. We tested the hypothesis that levels of MPO, MMP-8 and the ratio between MMP-8 and its regulator, tissue inhibitor of metalloproteinase (TIMP-1), are increased in acute ischemic stroke and its etiologic subgroups and they correlate with stroke severity. METHODS: In a cross-sectional case-control study, serum concentrations of MMP-8, MPO and TIMP-1 were assessed within 24 h after admission in 470 first-ever ischemic stroke patients and 809 age- and sex-matched controls, randomly selected from the population...

BACKGROUND: Polymerase δ-interacting protein 2 (Poldip2) is a multifunctional protein that regulates vascular extracellular matrix composition and matrix metalloproteinase (MMP) activity. The blood-brain barrier (BBB) is a dynamic system assembled by endothelial cells, basal lamina, and perivascular astrocytes, raising the possibility that Poldip2 may be involved in maintaining its structure. We investigated the role of Poldip2 in the late BBB permeability induced by cerebral ischemia...

Exercise training is a regular therapy for stroke patients in clinic. However, whether the early exercise is beneficial for stroke patients is still controversial. The review was performed in databases of OVID, PUBMED, and ISI Web of Science, from respective inception to December 2017. In this review, we summarize the effect of different exercise intensity, initiation time, and style on ischemic stroke. Moreover, the possible mechanism is also discussed. The conclusion is that the voluntary exercise is better in promoting the functional recovery following stroke compared to forced exercise; too early initiated exercise might play a harmful role following stroke, while early initiated exercise might exert benefits after stroke; mild and moderate intensity exercise training could generate better neuroprotection in comparison with high intensity exercise training; early excise training could regulate the process of brain edema, cell apoptosis, oxidative damage, stem cells and other mechanisms in order to exert neuroprotection for brain...

Reactive astrocytes induced by ischemia can transdifferentiate into mature neurons. This neurogenic potential of astrocytes may have therapeutic value for brain injury. Epigenetic modifications are widely known to involve in developmental and adult neurogenesis. PAX6, a neurogenic fate determinant, contributes to the astrocyte-to-neuron conversion. However, it is unclear whether microRNAs (miRs) modulate PAX6-mediated astrocyte-to-neuron conversion. In the present study we used bioinformatic approaches to predict miRs potentially targeting Pax6, and transient middle cerebral artery occlusion (MCAO) to model cerebral ischemic injury in adult rats...

Fluid-attenuated inversion recovery (FLAIR) vascular hyperintensity (FVH) is used to assess leptomeningeal collateral circulation, but clinical outcomes of patients with FVH can be very different. The aim of the present study was to assess a FVH score and explore its relationship with clinical outcomes. Patients with acute ischemic stroke due to middle cerebral artery M1 occlusion underwent magnetic resonance imaging and were followed up at 10 days (National Institutes of Health Stroke Scale) and 90 days (modified Rankin Scale) to determine short-term clinical outcomes...
