CDK5 as a Target to Reduce Cell Death Following Ischemic Stroke

In this study, we synthesized a membrane-permeable peptide (Tat-CDK5-CTM) that specifically disrupts the binding of CDK5 and NR2B and then leads to the degradation of CDK5 by a lysosome-mediated pathway. We found that the administration of Tat-CDK5-CTM not only retards calcium overload and neuronal death in oxygen and glucose deprivation (OGD)-treated neurons but also reduced the infarction area and neuronal loss and improved the neurological functions in MCAO (middle cerebral artery occlusion) mice. The peptide-directed lysosomal degradation of CDK5 is a promising therapeutic intervention for stroke. Link: https://doi.org/10.14336/AD.2018.1225

Carotid artery disease is a well-known cause of stroke. In Malaysia, stroke is the third most common cause of death [1]. To our knowledge, there is still limited information regarding stroke and its associated risk factors. Strokes from ischemic infarction of the brain is due to narrowing or occlusion from local thrombosis or embolization of a proximal thrombus. The incidence of ischemic stroke from carotid artery stenosis in an asymptomatic western population is approximately 2.7% according to a report from Netherlands by Hartog et al.

In conclusion, tetramethylpyrazine protected BMECs and inhibited platelets adhesion to BMECs after OGD/R injury, which was partially mediated by inhibiting P38 MAPK and NF-κB signaling pathways.

ConclusionThe polymorphisms Glu298Asp and C677T, affecting the eNOS and 5,10-MTHFR enzymes, respectively, and smoking, hypertension, and family history of stroke were associated with ischaemic stroke in young Mexican patients; this was not the case for the Thr325Ile, Ala147Thr, 4 G/5 G, and PLA1/A2 polymorphisms of the genes coding for fibrinolytic proteins and platelet receptors.ResumenIntroducciónDiversos polimorfismos en genes candidatos que codifican proteínas del sistema hemostático se han propuesto como factores de riesgo para el desarrollo de trombosis.MétodosCasos y controles, ...

Complete spontaneous thrombosis of intracranial aneurysms is uncommon. Although this type of thrombosis is largely asymptomatic, in rare cases it can be accompanied by parent artery occlusion and ischemic stroke. There are limited reports of complete thrombosis of an unruptured aneurysm of the internal carotid artery and middle cerebral artery. Furthermore, there are no reports of occlusion of the vertebral artery caused by thrombosis of an aneurysm. The mechanisms of spontaneous thrombosis are not established.

AbstractPatients with atrial fibrillation (AF) who suffer an acute ischemic stroke are at risk for both hemorrhagic transformation and recurrent ischemic stroke in the acute post ‐stroke period. Oral anticoagulants are recommended for secondary stroke prevention in patients with AF. The optimal time to initiate anticoagulant therapy after acute ischemic stroke in patients with AF is uncertain. There is concern that early initiation increases the risk of hemorrhagic transfo rmation, whereas delayed initiation leaves the patient at risk for recurrent ischemic stroke. In this article, we provide a review of the risk of hemo...

ConclusionsThe most frequent causes of cSAH in our series were cerebral amyloid angiopathy, ischaemic stroke, and vasculitis. This type of haemorrhage has a worse prognosis than other non-aneurysmal cSAH. There are numerous possible causes, and prognosis depends on the aetiology. In elderly patients, intracranial haemorrhage is frequently associated with cognitive impairment.ResumenIntroducciónLas hemorragias subaracnoideas corticales (HSAc) tienen numerosas etiologías. No hay estudios prospectivos que indiquen su evolución a largo plazo. El objetivo de este trabajo es describir las característi...

Abstract Background: Aphasia negatively impacts quality of life. This is the first Brazilian study that investigates the prevalence of aphasia and its related factors, the results of which may underpin hospital and health service planning for this vulnerable population.Objective: To establish the prevalence of aphasia in patients after first-ever ischemic stroke (FEIS) and associated factors.Methods: This is a retrospective cohort study, based on a database held in Joinville, Brazil. All cases of FEIS admitted to one public hospital in Joinville in 2015 were selected. The diagnosis of aphasia was verified by neuro...
