1. 1. Prognostic markers in prostate cancer : studies of a watchful waiting cohort with long follow up

   Författare :Andreas Josefsson; Anders Bergh; Pernilla Wikström; Pär Stattin; Anders Bjartell; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; Immunohistochemistry; Prognostic markers; biomarkers; Survival analysis; human; pathology; watchful waiting; tissue micro array; Endoglin; von willebrandt factor; ki67; ki-67; hyaluronan; patologi; Pathology;

   Sammanfattning : Background: Prostate Cancer (PC) is a common and highly variable disease. Using current diagnostic methods, the prostate specific antigen (PSA) blood test and histological grading of prostate tissue needle biopsies, it is often difficult to evaluate whether the patient has a PC that requires active treatment or not.

3. 2. Microdosimetry of radiohalogens in thyroid models

   Författare :Anders Josefsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microdosimetry; radiohalogens; radioiodine; astatine-211; thyroid gland; man; rat; mouse;

   Sammanfattning : The radiohalogens 123I, 124I, 125I, 131I, and 211At are routinely used or proposed for diagnostic and therapeutic purposes. The different characteristics and application areas of these radioiodine isotopes, together with the possibility to bind them to the same carrier molecule, give many advantages, for example, by enabling relevant biodistribution and dosimetric studies important for dose-planning before radionuclide therapy.

4. 3. Wide-angle scanning wide-band phased array antennas

   Författare :Anders Ellgardt; Martin Norgren; Lars Josefsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

   Sammanfattning : This thesis considers problems related to the design and the analysis of wide-angle scanning phased arrays. The goals of the thesis are the design and analysis of antenna elements suitable for wide-angle scanning array antennas, and the study of scan blindness effects and edge effects for this type of antennas.

5. 4. Attrition in Studies of Cognitive Aging

   Författare :Maria Josefsson; Xavier de Luna; Lars Nyberg; Anders Lundquist; Mattias Villani; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attrition; missing data; age-related cognitive change; non- ignorable dropout; monotone missing pattern; mixture models; pattern- mixture models; imputation; Statistics; statistik;

   Sammanfattning : Longitudinal studies of cognition are preferred to cross-sectional stud- ies, since they offer a direct assessment of age-related cognitive change (within-person change). Statistical methods for analyzing age-related change are widely available. LÄS MER

7. 5. Mindfulness : Relations to attention regulation, decentering, and psychological well-being

   Författare :Torbjörn Josefsson; Anders Broberg; Harald Walach; Högskolan i Halmstad; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attention; buddhism; decentering; mediation analysis; meditation; mindfulness; psychological well-being;

   Sammanfattning : The current research project consists of three separate studies. The general aim of this project was to contribute to previous mindfulness research by exploring fundamental aspects of mindfulness in an effort to increase the understanding of mindfulness as a construct as well as its mechanisms.
