2. 1. MRI Diagnosis of Intracranial Hemorrhage : Experimental and Clinical Studies

   Author : Montserrat Alemany Ripoll; Kaj Ericsson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; hemorrhage; experimental; MRI; T2*-w GE sequence; old microhemorrhages; stroke; Radiologisk forskning; Radiological research; Radiologisk forskning; radiologi; Radiology;

   Abstract : The purpose of this work was to improve the diagnosis of intracranial hemorrhage with MRI, using, among others, T2*-w GE sequences. Various sequences were tested in rabbits at two magnetic field strengths. Then, the most effective technique was applied to stroke patients. READ MORE

4. 2. Estrogen signaling in stroke : genetic and experimental studies

   Author : Magnus Strand; Tommy Olsson; Jan Hillert; Umeå universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; intracerebral hemorrhage; ischemic stroke; genetics; ERα; OPG; 17β-estradiol; enriched environment; learning and memory; hippocampus; NGFI-A; Medicine; Medicin;

   Abstract : Stroke is a common and multifactorial disease influenced by genetic and environmental risk factors. It is a highly heterogeneous entity consisting of two main types, ischemic (80%) and hemorrhagic (20%) stroke. The most common form of hemorrhagic stroke is intracerebral hemorrhage (ICH). READ MORE

5. 3. Risk factors in ischemic stroke

   Author : Katarina Jood; Göteborgs universitet; []
   Keywords : stroke; ischemic stroke subtypes; genetics; polymorphism; fibrinolysis; obesity; stress;

   Abstract : Ischemic stroke is a complex disease in which environmental and genetic factors make about equal contributions to the etiology. However, knowledge regarding the molecular basis of the genetic influence and the impact of specific lifestyle factors is limited. READ MORE

6. 4. Stroke during cardiac surgery : risk factors, mechanisms and survival effects

   Abstract : Ischemic stroke causes millions of deaths around the world each year, and surviving patients often suffer from long-term disability. Hundreds of promising drug candidates have been identified in animal models, but the clinical trials have repeatedly failed. Lack of methodological quality in the animal studies, e.g. READ MORE
