Remote ischemic postconditioning (RIPostC) is a promising therapeutic intervention whereby brief episodes of ischemia/reperfusion of one organ (limb) mitigate damage in another organ (brain) that has experienced severe hypoxia-ischemia. Our aim was to assess whether RIPostC is protective following cerebral hypoxia-ischemia in a piglet model of neonatal encephalopathy (NE) using magnetic resonan...
BACKGROUND AND PURPOSE White matter changes (WMC) are a common finding on brain imaging and are associated with an increased risk of ischemic stroke. They are most frequent in small vessel stroke; however, in the absence of comparisons with normal controls, it is uncertain whether WMC are also more frequent than expected in other stroke subtypes. Therefore, we compared WMC in pathogenic subtype...
Premature birth is a major public health issue internationally affecting 13 million babies worldwide. Hypoxia and ischemia is probably the commonest type of acquired brain damage in preterm infants. The clinical manifestations of hypoxic-ischemic injury in survivors of premature birth include a spectrum of cerebral palsy and intellectual disabilities. Until recently, the extensive brain abnorma...
BACKGROUND AND PURPOSE Neuronal replacement has recently gained attention as a potential therapeutic target under ischemic conditions. However, the oligodendrogenic infrastructure is equally critical for restoration of brain function and is also sensitive to ischemic injury. Erythropoietin (EPO) is a neuroprotective molecule that stimulates neuronal replacement after neonatal hypoxia/ischemia (...
BACKGROUND AND PURPOSE Cerebral blood flow (CBF) abnormalities are previously demonstrated in white matter disease. A gradation of change may exist between patients with mild and more severe white matter disease. An association between blood brain barrier dysfunction, increasing age and white matter disease is also suggested. The purpose of this study was to quantify and correlate white matter ...
OBJECTIVE White matter remodeling plays an important role in neurological recovery after stroke. Bone marrow stromal cells (BMSCs) and Niaspan, an agent which increases high density lipoprotein (HDL), each induces neurorestorative effects and promotes white matter remodeling after stroke in non-diabetic rats. In this study, we test whether combination of BMSCs with Niaspan induces an enhanced w...
Survivors of premature birth have a predilection for perinatal brain injury, especially to periventricular cerebral white matter. Periventricular white matter injury (PWMI) is now the most common cause of brain injury in preterm infants and the leading cause of chronic neurological morbidity. The spectrum of chronic PWMI includes focal cystic necrotic lesions (periventricular leukomalacia) and ...
