O-linked β-N-acetylglucosaminylation (O-GlcNAcylation) is involved in the regulation of many cellular cascades and neurological diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and stroke. In the brain, the expression of O-GlcNAcylation is notably heightened, as is that of O-linked N-acetylglucosaminyltransferase (OGT) and β-N-acetylglucosaminidase (OGA), the presence of which is prominent in many regions of neurological importance. Most importantly, O-GlcNAcylation is believed to contribute to the normal functioning of neurons; conversely, its dysregulation participates in the pathogenesis of neurological disorders...

BACKGROUND: Spontaneous thalamic hemorrhage has increased in incidence in recent years. The characteristics of thalamic hemorrhage were analyzed based on the vascular territories of the thalamus. METHODS: Retrospective analysis included 303 consecutive patients with spontaneous thalamic hemorrhage. Thalamic hemorrhage was classified into four types: anterior type (supplied mainly by the tuberothalamic artery), medial (mainly paramedian thalamic-subthalamic artery), lateral (mainly thalamogeniculate artery), and posterior (mainly posterior choroidal artery)...

Statins have been shown to decrease stroke risk in patients with cardiovascular risk factors but not to prevent recurrence of ischemic stroke in patients with atrial fibrillation (AF). The present subanalysis aimed to clarify the efficacy of combined use of warfarin and statins in patients with nonvalvular AF (NVAF) with coronary artery disease, diabetes mellitus (DM), or hypertension. The effects of adding statins to warfarin were compared with those of warfarin alone in patients with NVAF with the data set of J-RHYTHM Registry, a prospective, observational study with a 2-year follow-up...

Moyamoya syndrome occurs in sickle cell disease (SCD) as a secondary complication of large-artery stenosis. Moyamoya increases the risk of stroke, but its optimal management in SCD is not established.  Encephaloduroarteriosynangiosis (EDAS) is a neurosurgical revascularization procedure for moyamoya whose use has been reported in SCD patients. We report the outcomes of 11 patients with SCD systematically evaluated for EDAS by a multidisciplinary team and compare the rate of stroke in patients who received EDAS to those who did not...

INTRODUCTION: An ischemic stroke is an event that occurs due to cerebral vascular disease and is directly related to the degree of vascular damage. This process is associated with atherosclerosis progression and is influenced by the presence of cardiovascular risk factors. AIMS: One of the goals of our research was to examine whether specific medications used for treating hypertension are associated with the development of strokes. METHODS: In a retrospective study of patients who were hospitalized between the years 2003-2008 due to a cerebrovascular accident (CVA) or a transient ischemic attack (TIA), 916 cases of stroke patients were reviewed...

Accounting for high mortality and morbidity rates, intracerebral hemorrhage (ICH) remains one of the most detrimental stroke subtypes lacking a specific therapy. Neuroinflammation contributes to ICH-induced brain injury and is associated with unfavorable outcomes. This study aimed to evaluate whether α7 nicotinic acetylcholine receptor (α7nAChR) stimulation ameliorates neuroinflammation after ICH. Male CD-1 mice and Sprague-Dawley were subjected to intracerebral injection of autologous blood or bacterial collagenase...

Data from randomized clinical trials and current guidelines suggest that patients with anterior circulation occlusion with contraindications to intravenous thrombolysis may benefit from direct mechanical thrombectomy. Nevertheless, no data are available on the efficacy and safety of direct mechanical thrombectomy in patients with concomitant spontaneous intracerebral hemorrhage. We report the case of a 51-year-old woman with a spontaneous intracerebral hemorrhage in the right parietal and occipital lobes, who experienced, 7 days later, an occlusion of the proximal left middle cerebral artery...

BACKGROUND AND PURPOSE: Subarachnoid hemorrhage (SAH) is a devastating form of stroke with neurological outcomes dependent on the occurrence of delayed cerebral ischemia. It has been shown in rodents that some of the mechanisms leading to delayed cerebral ischemia are related to a decreased circulation of the cerebrospinal fluid (CSF) within the brain parenchyma. Here, we evaluated the cerebral circulation of the CSF in a nonhuman primate in physiological condition and after SAH. METHODS: We first evaluated in physiological condition the circulation of the brain CSF in Macaca facicularis, using magnetic resonance imaging of the temporal DOTA-Gd distribution after its injection into the CSF...

BACKGROUND AND PURPOSE: Admission hyperglycemia is associated with a poor outcome in acute ischemic stroke. How hyperglycemia impacts the pathophysiology of acute ischemic stroke remains largely unknown. We investigated how preexisting hyperglycemia increases ischemia/reperfusion cerebral injury. METHODS: Normoglycemic and streptozotocin-treated hyperglycemic rats were subjected to transient middle cerebral artery occlusion. Infarct growth and brain perfusion were assessed by magnetic resonance imaging...

Exosomes are gaining importance because they show great promise in therapeutic applications for several diseases. Particularly in stroke, exosomes derived from mesenchymal stem cell (MSC) therapy work as paracrine effectors responsible for promoting neurovascular remodeling and functional recovery. Adult male rats were subjected to intracerebral hemorrhage (ICH) by intrastriatal injection of collagenase type IV; 24 h after surgery, MSC-derived exosomes were administered through the tail vein. The rats were euthanized at 7 or 28 days after treatment...
