Cerebral proliferative angiopathy (CPA) is an infrequent vascular malformation. It is composed of a nidus, arterial feeders, and venous drainage. Some special features differentiate it from the common arteriovenous malformations (AVM). The nidus has normal cerebral tissue intermingled and occupies a large portion of the brain. There is a frequent transdural arterial supply. Arterial feeders and draining veins are of small caliber concerning the nidus size. Ischemic strokes are the most common clinical event...

Post-stroke locomotion is usually characterized by asymmetrical gait patterns, compensatory movements of trunk and nonparetic limb, altered motor coordination, and wide inter-stride variability. This pilot study was designed to test a twofold hypothesis: post-stroke survivors can exploit the redundancy of the segmental angles to stabilize the 3D footpath trajectory during the swing phase, in accordance with the Uncontrolled Manifold (UCM) theory; an intense rehabilitative treatment improves both motor performance and outcomes of the UCM analysis...

We report a case of ischemic stroke in an apparently healthy 35-year-old gravida 2 para 1 who was treated with tissue-type plasminogen activator (tPA) 9 hours after vaginal delivery that resulted in severe hemorrhage. Limited data suggest use of thrombolytics in pregnancy is safe, but there is a paucity of evidence assessing their use immediately postpartum. We describe successful combination of tPA with endovascular mechanical thrombectomy (EMT) for treatment of postpartum stroke, which was followed by extensive uterine bleeding...

The blood-brain barrier (BBB) damage is a momentous pathological process of ischaemic stroke. NADPH oxidases 4 (NOX4) boosts BBB damage after ischaemic stroke and its expression can be influenced by microRNAs. This study aimed to probe into whether miR-92b influenced the BBB damage after ischaemic stroke by regulating NOX4 expression. Here, miR-92b expression was lessened in the ischaemic brains of rats and oxygen-glucose deprivation (OGD)-induced brain microvascular endothelial cells (BMECs). In middle cerebral artery occlusion (MCAo) rats, miR-92b overexpression relieved the ameliorated neurological function and protected the BBB integrity...

Intracerebral hemorrhage (ICH) has the highest mortality rate of all stroke subtypes but an effective treatment has yet to be clinically implemented. Transforming growth factor‑β1 (TGF‑β1) has been reported to modulate microglia‑mediated neuroinflammation after ICH and promote functional recovery; however, the underlying mechanisms remain unclear. Non‑coding RNAs such as microRNAs (miRNAs) and competitive endogenous RNAs (ceRNAs) have surfaced as critical regulators in human disease. A known miR‑93 target, nuclear factor erythroid 2‑related factor 2 (Nrf2), has been shown to be neuroprotective after ICH...

Remote ischemic conditioning (RIC) is a noninvasive procedure whereby several periods of ischemia are induced in a limb. Although there is growing interest in using RIC to improve stroke recovery, preclinical RIC research has focused exclusively on neuroprotection, using male animals and the intraluminal suture stroke model, and delivered RIC at times not relevant to either brain repair or behavioral recovery. In alignment with the Stroke Recovery and Rehabilitation Roundtable, we address these shortcomings...

BACKGROUND: Motor recovery after stroke in humans and in rodent models is time sensitive. Recovery in patients is a result of biological spontaneous recovery via endogenous repair mechanisms and is likely improved by enhancing the synaptic plasticity required for endogenous repair. Cerebrolysin is a polypeptide preparation known to enhance neuroplasticity and may improve recovery in patients. In mice, we tested the hypothesis that Cerebrolysin can act poststroke to enhance both spontaneous and training-associated motor recovery...

Lymphocyte-related blood parameters (LRBP), including neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio, and lymphocyte-monocyte ratio, could reflect a patient's overall inflammatory status. We aimed to clarify the association between preoperative LRBP and outcomes of type B aortic dissection (TBAD) patients undergoing thoracic endovascular aortic repair (TEVAR). A total of 841 patients were enrolled from 2010 to 2017. Twenty-six (3.1%) patients died during hospitalization and 71 (8.7%) patients died after a median follow-up of 47...

Intestinal barrier integrity and function are compromised during exertional heat stress (EHS) potentially leading to consequences that range from minor gastrointestinal (GI) disturbances to fatal outcomes in exertional heat stroke or septic shock. This mini-review provides a concise discussion of nutritional interventions that may protect against intestinal permeability during EHS and suggests physiological mechanisms responsible for this protection. Although diverse nutritional interventions have been suggested to be protective against EHS-induced GI permeability, the ingestion of certain amino acids, carbohydrates, and fluid per se are potentially effective strategies, whereas evidence for various polyphenols and pre/probiotics is developing...

Background : Social determinants of health (SDOH) may limit the practice of COVID-19 risk mitigation guidelines with health implications for individuals with underlying cardiovascular disease (CVD). Population-based evidence of the association between SDOH and practicing such mitigation strategies in adults with CVD is lacking. We used the National Opinion Research Center's COVID-19 Household Impact Survey conducted between April and June 2020 to evaluate sociodemographic disparities in adherence to COVID-19 risk mitigation measures in a sample of respondents with underlying CVD representing 18 geographic areas of the United States (US)...

Matrix-assisted laser desorption/ionization-mass spectrometry imaging (MALDI-MSI) of lipids is considered one of the shotgun lipidomic techniques that explores the in situ distribution of lipids in tissue sections. To successfully perform this task, knowledge and experience in the conventional cryosection, tissue section collection and handling, and mass spectrometry data analysis and signal processing are needed. A MALDI-MSI protocol covering from the fresh organ collection, cryosection and tissue processing, matrix application, MSI data acquisition, to the final MSI display of lipid distribution in the brain section of an ischemic stroke rat is described to exemplify this technique...

MYC is well known as a potent oncogene involved in regulating cell cycle and metabolism. Augmented MYC expression leads to cell cycle dysregulation, intense cell proliferation, and carcinogenesis. Surprisingly, its increased expression in neurons does not induce their proliferation, but leads to neuronal cell death and consequent development of a neurodegenerative phenotype. Interestingly, while cancer and neurodegenerative diseases such as Alzheimer's disease are placed at the opposite sides of cell division spectrum, both start with cell cycle dysregulation and stimulation of proliferation...
