1. 16. Biomarkers In Brain Tumors With Focus On Glioblastoma

   Författare :Malgorzata Lysiak; Peter Söderkvist; Annika Malmström; Olle Stål; Mattias Belting; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma; MGMT; Biomarker; Sex differences; Androgen receptor; Loss of chromosome Y;

   Sammanfattning : The primary brain tumors, gliomas, are not very common but they are deadly. Each year in Sweden around 500 patients will be diagnosed with a glioma and unfortunately most of them will have the most aggressive type, glioblastoma (GBM). Median survival, even if treated, is poor (14-17 months). LÄS MER

3. 17. Transcriptomic cellular diversity of the early human developing brain

   Författare :Emelie Paula Braun; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The complexity of the mammalian brain is partly reflected in its cell type diversity which influences the function of neurons that encode the behavior of animals. Brain cell type diversity emerges during embryonic stages, a critical period when neurons start to become functionally active and establish their connectivity across the brain. LÄS MER

4. 18. Brain networks in time : deriving and quantifying dynamic functional connectivity

   Författare :William Hedley Thompson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Studying the brain’s structure and function as a network has provided insight about the brain’s activity in health and disease. Networks in the brain are often averaged over trials, frequency and time and this is called functional connectivity. This thesis aims to extend the analyses beyond these assumptions and simplifications. LÄS MER

5. 19. Stereotactic imaging in functional neurosurgery

   Författare :Hidehiro Hirabayashi; Patric Blomstedt; Takaomi Taira; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Deep brain stimulation; pallidotomy; thalamotomy; Parkinson s disease; essential tremor; CT; MRI; neurokirurgi; Neurosurgery;

   Sammanfattning : Background: The birth of stereotactic functional neurosurgery in 1947 was to a great extent dependent on the development of ventriculography. The last decades have witnessed a renaissance of functional stereotactic neurosurgery in the treatment of patients with movement disorders. LÄS MER

7. 20. Combining Shape and Learning for Medical Image Analysis

   Författare :Jennifer Alvén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feature-based registration; convolutional neural networks; conditional random fields; medical image segmentation; random decision forests; machine learning; multi-atlas segmentation; medical image registration; shape models;

   Sammanfattning : Automatic methods with the ability to make accurate, fast and robust assessments of medical images are highly requested in medical research and clinical care. Excellent automatic algorithms are characterized by speed, allowing for scalability, and an accuracy comparable to an expert radiologist. LÄS MER
