Spontaneous intracerebral hemorrhage during acute and chronic hypertension in mice.
Oxidative stress and matrix metalloproteinases (MMPs) contribute to hemorrhagic transformation after ischemic stroke and brain injury after intracerebral hemorrhage (ICH). The goal of this study was to develop a new model of spontaneous ICH, based on the hypothesis that acute, superimposed on chronic, hypertension produces ICH. We hypothesized that increases in angiotensin II (AngII)-mediated o...
متن کاملContractile properties of human placental anchoring villi.
The presence of myofibroblasts arranged parallel to the longitudinal axes of anchoring villi of the placenta has previously been described. Furthermore, it has been suggested that intraplacental blood volume, and hence fetal-maternal oxygen-nutrient exchange, may in part be regulated through the longitudinal contraction of anchoring villi. We demonstrate here that anchoring villi have the abili...
متن کاملMorphological analysis of degeneration and regeneration of syncytiotrophoblast in first trimester placental villi during organ culture.
We have recently shown using dansyl-L-lysine exclusion studies that the release of human chorionic gonadotrophin (HCG) in conjunction with L-lactate dehydrogenase (LDH) from first trimester villi during organ culture is symptomatic of syncytiotrophoblast degeneration. The purpose of this study was to examine chorionic villi at the ultrastructural level in order to determine events occurring dur...
متن کاملA study of the factors associated with non-traumatic intracerebral hemorrhage (ICH) in patients with chronic systemic hypertension
Objective: Intracerebral hemorrhage (ICH) following systemic and chronic hypertension is one of the main causes of acute stroke leading to disability and death. Identifying the risk factors in ICH patients can be effective in reducing bleeding and the rates of mortality and disability in these patients. This study was carried out to investigate the factors associated with ICH.Methods: A t...
متن کاملCerebellar hemorrhage in utero associated with ‘massive’ fetal thrombotic vasculopathy
Background: Cerebellar hemorrhage is a rare but serious perinatal condition with various etiologies leading to fetal and neonatal death and adverse neurological complications. Complete autopsy and placental examination are essential for identification of a cause of the bleeding. Objective: Present a case of cerebellar hemorrhage in utero associated with ‘massive’ fetal thrombotic vasculopathy (...
