1. 16. Estrogens and lymphoma growth

   Författare :Muhammad Sharif Hasni; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Lymphomas are generally not considered as endocrine-associated cancers. Nevertheless, most lymphoid malignancies show a gender differencein incidence and prognosis, with males being more affected.The molecular mechanism for this gender difference is unknown. LÄS MER

3. 17. Three - dimensional ultrasound studies of the cervix in pregnancy

   Författare :Linas Rovas; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrology; gynaecology; Obstetrics; Prostaglandin .; Labor induction .; Spontaneous delivery .; Pregnancy .; Cervix uteri .; Blood flow indices .; Doppler ultrasound .; Three-dimensional imaging .; sexuality; reproduction; Obstetrik; sexualitet; reproduktion; gynekologi; andrologi;

   Sammanfattning : The aim of this thesis was to evaluate cervical physiological changes by three-dimensional (3D) ultrasound during pregnancy and to investigate the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy. The thesis is based on five studies: reproducibility of cervical measurements by 3D power Doppler ultrasound (study I), reference data representative normal findings of the cervix assessed by 3D ultrasound during pregnancy (studies II, III) and the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy.

4. 18. Strategies to improve macroencapsulated islet graft survival

   Författare :Anne Sörenby; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Chronic immunosuppressive therapy may have severe side-effects. In cell transplantation, the graft can be encapsulated within a membrane chamber, providing a physical barrier against the immune system. The cell graft then becomes dependent on the diffusion of nutrients and oxygen from the surrounding microcirculation. LÄS MER

5. 19. Role of estrogen receptor beta in epithelia lacking estrogen receptor alpha expression

   Författare :Andrea Morani; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Estrogen Receptors; Extracellular Matrix; Prostate Cancer; Lung Diseases; Ovarian Follicle;

   Sammanfattning : Estrogens influence the physiology of many organs by activation of the nuclear receptors ERalpha and ERbeta. The epithelium of ventral prostate, ovarian granulosa cells and lung, are ERalpha-negative but express high levels of ERbeta. This thesis focuses on the role played by ERbeta in ERalpha-negative epithelium. LÄS MER

7. 20. The mode of action of the radiosensitizing analogs metoclopramide and nicotinamide

   Författare :Anders Olsson; Lund Wallenberg Neurocentrum; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; metoclopramide; nicotinamide; apoptosis; radiosensitization; NAD; benzamide; DNA repair; Clinical physics; tomography; radiology; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Sammanfattning : This thesis provides the first attempt to study the nicotinamides and benzamides from a mode of action point of veiw. Understanding the effects on DNA repair, cell cycle control (proliferation) and cell death from these agents and in combination with ionizing radiation, provides a new opportunity to logically develop better approaches to sensitize already existing therapies via for example induction of apoptosis or inhibition of DNA repair.
