   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Smoking; tobacco; prevention; intervention; adolescents; schools; evaluation; parents; Public health science; Folkhälsovetenskap; Epidemiology; epidemiologi;

   Sammanfattning : There is a robust evidence base for the negative health effects from smoking. Smoking is linked to severe morbidity and to mortality, and kills up to half of its regular users. LÄS MER

3. 22. Recurrent pain and health related quality of life in young schoolchildren

   Författare :Solveig Petersen; Erik Bergström; Bruno Hägglöf; Sven Bremberg; Umeå universitet; []
   Nyckelord :Pediatrics; Abdominal pain; Back pain; Child; Headache; Pain; Psychometrics; Quality of Life; Schools; validation studies; Pediatrik; pediatrik; Pediatrics;

   Sammanfattning : The objectives of this thesis were 1) to describe the occurrence and co-occurrence of recurrent pain (headache, stomach-ache, and backache) in young school children; 2) to describe Health Related Quality of Life (HRQoL) in these children, from the perspective of the child, 3) to examine the psychometric properties of the PedsQL, a pediatric HRQoL instrument. Three data collections were performed, two in Umeå, Sweden, and one in a nearby smaller municipality, Lycksele. LÄS MER

5. 24. Prognostic Biomarkers and Target Proteins for Treatment of High-grade Gliomas

   Författare :Linda Sooman; Simon Ekman; Johan Lennartsson; Joachim Gullbo; Michael Bergqvist; Erik Blomquist; Stefan Bergström; Beatrice Melin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; High-grade glioma; prognostic biomarkers; combination chemotherapy; DNA methylation; FGF2; p38 MAPK; PTPN6; camptothecin; imatinib; vandetanib; EGFR; RAC1; Notch; Medical Science; Medicinsk vetenskap; Oncology; Onkologi;

   Sammanfattning : The survival for high-grade glioma patients is poor and the treatment may cause severe side effects. A common obstacle in the treatment is chemoresistance. To improve the quality of life and prolong survival for these patients prognostic biomarkers and new approaches for chemotherapy are needed. LÄS MER

7. 25. Mesoscale Processes over the Baltic Sea

   Författare :Nina Svensson; Erik Sahlée; Hans Bergström; Anna Rutgersson; Søren Larsen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary layer; Baltic Sea; stable conditions; low-level jet; sea breeze; boundary layer rolls; mesoscale effects; WRF; LIDAR;

   Sammanfattning : The objective of this thesis is to study mesoscale processes above the Baltic Sea, which is a small, semi-enclosed sea where land-sea interaction may have a large impact on the offshore conditions. It is only the last tens of years that offshore research has become more popular, and one reason for this is the increasing offshore wind energy, which poses the need for accurate estimates of wind speed and turbulence conditions in the marine environment.
