Ultrasound-enhanced systemic thrombolysis for acute ischemic stroke.
- A. Alexandrov, C. Molina, +9 authors A. Wojner
- The New England journal of medicine
- 18 November 2004
BACKGROUND Transcranial Doppler ultrasonography that is aimed at residual obstructive intracranial blood flow may help expose thrombi to tissue plasminogen activator (t-PA). Our objective was to… Expand
Microbubble administration accelerates clot lysis during continuous 2-MHz ultrasound monitoring in stroke patients treated with intravenous tissue plasminogen activator.
BACKGROUND AND PURPOSE We sought to evaluate the effects of administration of microbubbles (MBs) on the beginning, speed, and degree of middle cerebral artery (MCA) recanalization during systemic… Expand
Molecular signatures of brain injury after intracerebral hemorrhage
BackgroundThe mechanisms of cellular death in the tissue surrounding an intracerebral hemorrhage (ICH) are not defined. ObjectiveTo investigate the relationship of markers of excitotoxicity and… Expand
MMP-9–Positive Neutrophil Infiltration Is Associated to Blood–Brain Barrier Breakdown and Basal Lamina Type IV Collagen Degradation During Hemorrhagic Transformation After Human Ischemic Stroke
- A. Rosell, E. Cuadrado, A. Ortega-Aznar, M. Hernández-Guillamon, E. Lo, J. Montaner
- 1 April 2008
Background and Purpose— An abnormal expression of some matrix metalloproteinases (MMPs) is related with hemorrhagic transformation events after stroke. Our aim was to investigate MMP-2 and MMP-9 in… Expand
Genetic risk factors for ischaemic stroke and its subtypes (the METASTROKE Collaboration): a meta-analysis of genome-wide association studies
Summary Background Various genome-wide association studies (GWAS) have been done in ischaemic stroke, identifying a few loci associated with the disease, but sample sizes have been 3500 cases or… Expand
Variants at APOE influence risk of deep and lobar intracerebral hemorrhage
Prior studies investigating the association between APOE alleles ε2/ε4 and risk of intracerebral hemorrhage (ICH) have been inconsistent and limited to small sample sizes, and did not account for… Expand
Matrix Metalloproteinase-9 Pretreatment Level Predicts Intracranial Hemorrhagic Complications After Thrombolysis in Human Stroke
Background—Matrix metalloproteinase (MMP) expression is related to blood brain barrier disruption after cerebral ischemia. Moreover, MMP inhibitors reduce hemorrhagic transformation (HT) after… Expand
Increased Brain Expression of Matrix Metalloproteinase-9 After Ischemic and Hemorrhagic Human Stroke
Background and Purpose— Abnormal expression of some matrix metalloproteinases (MMP) has shown to play a deleterious role in brain injury in experimental models of cerebral ischemia. We aimed to… Expand
Temporal Profile of Matrix Metalloproteinases and Their Inhibitors After Spontaneous Intracerebral Hemorrhage: Relationship to Clinical and Radiological Outcome
Background and Purpose— Matrix metalloproteinases (MMPs) are related to blood–brain barrier disruption, and some members of this family have been recently involved in brain bleedings. We aimed to… Expand
Metalloproteinase and stroke infarct size: role for anti‐inflammatory treatment?
- Anna Morancho, A. Rosell, Lidia García-Bonilla, J. Montaner
- Annals of the New York Academy of Sciences
- 1 October 2010
Deregulation of matrix metalloproteinases (MMPs), the largest class of human proteases, has been implicated in brain damage in both animal and human studies. Some MMPs are elevated after stroke (both… Expand
