1. 16. Studies on energy expenditure in walking after stroke

   Författare :Anna Danielsson; Göteborgs universitet; []
   Nyckelord :gait; rehabilitation; assessment; physical therapy; oxygen consumption; body weight support; orthotic devices; physical activity;

   Sammanfattning : Aims: The aims were to assess energy expenditure during different conditions, evaluate measurement methods and assess physical activity after stroke. Methods: In total 51 persons with stroke >6 months previously (mean age 56) and 24 reference persons participated. LÄS MER

3. 17. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

   Författare :Vladimir Kirejev; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

   Sammanfattning : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. LÄS MER

4. 18. Mortality in Oxygen-Dependent Chronic Obstructive Pulmonary Disease and Possibilities for Pharmacological Interventions

   Författare :Magnus Ekström; allergologi och palliativ medicin Lungmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; COPD; mortality; survival; comorbidity; cardiovascular disease; cardiovascular drugs; angiotensin-converting enzyme inhibitor; angiotensin receptor blocker; beta blocker; statin; aspirin; antiplatelet drug; gender; sex; oxygen-dependent; LTOT; trends; excess mortality; SMR; hypoxemia; hypoxia; hypoxaemic;

   Sammanfattning : Background Chronic obstructive pulmonary disease (COPD) is a major and rising cause of mortality worldwide, especially in women. Patients with chronic hypoxia owing to COPD are treated with long-term oxygen therapy (LTOT) but have high morbidity and mortality. LÄS MER

5. 19. Photodynamic therapy and laser-based diagnostic studies of malignant tumours

   Författare :Ingrid Wang; Medicinskt lasercentrum; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protoporphyrin IX PpIX ; delta -aminolevulinic acid ALA ; photosensitizer; basal cell carcinoma BCC ; Photodynamic therapy PDT ; laser-induced fluorescence LIF ; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

   Sammanfattning : Two non-thermal regimens of light interaction with biological tissue, that are in a natural way connected, are discussed in the present thesis. These are photodynamic therapy (PDT) for the treatment of malignant tumours and laser-induced fluorescence (LIF) for tissue characterization. LÄS MER

7. 20. Mitochondria : a target for anticancer therapy

   Författare :Björn Kruspig; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Mitochondria possess a central role in several cellular metabolic pathways, maintenance of calcium homeostasis, production of reactive oxygen species (ROS) and in the regulation of various cell death modalities. A majority of cancers demonstrate aberrations in mitochondrial functions, which were shown to contribute to tumourigenesis. LÄS MER
