1. 16. Constituting the Healthy Employee? : Governing gendered subjects in workplace health promotion

   Författare :Erika Björklund; Britt-Marie Berge; Jan Wright; Håkan Larsson; Högskolan i Gävle; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Workplace health promotion; health education; physical activity; diet; discourse; governmentality; bio-power; gender; Education; Pedagogik; Gender studies; Genus; Public health science; Folkhälsovetenskap;

   Sammanfattning : With a post-structural approach and an analytical focus on processes of governmentality and biopower, this study is concerned with how discourses of health are contextualized in educational practice and interaction between educators and participants in workplace health promotion (WHP) interventions. Of concern are issues of the discursive production, regulation and representation of power, knowledge and subjects as gendered beings in workplace health promotion interventions. LÄS MER

3. 17. Structural design and properties of hydrogel biomaterials

   Författare :Mikael Larsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyacrylic acid; Mechanical properties; Microfibrillated cellulose; Drug release; Chitosan; Biomaterials; Swelling; Hydrogels;

   Sammanfattning : Today a range of materials are used in medical applications; such materials are collectively denoted as biomaterials. A special class of biomaterials currently given much scientific interest is hydrogels. In particular a contemporary research topic is to create multicomponent materials in which synergetic effects are achieved. LÄS MER

4. 18. Microgel Interactions with Peptides and Proteins : Consequence of Peptide and Microgel Properties

   Författare :Ronja Widenbring; Martin Malmsten; Per Hansson; Catherine Picart; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Binding; Degradation; Enzyme; Gel; Hydrogel; Microgel; Peptide; Protein; Release; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

   Sammanfattning : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.

5. 19. Interactions between platelets and complement with implications for the regulation at surfaces

   Författare :Per H. Nilsson; Kristina Nilsson Ekdahl; John Lambris; Ian Nicholls; Berhane Ghebrehiwet; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; complement system activation; regulation ; platelets activation; regulation ; biomaterials; biocompatibility; chondroitin sulfate-A; apyrase; C1q; C3; factor H; C4BP; ADP; Biomedical Sciences; Biomedicinsk vetenskap;

   Sammanfattning : Disturbances of host integrity have the potential to evoke activation of innate immunologic and hemostatic protection mechanisms in blood. Irrespective of whether the activating stimulus is typically immunogenic or thrombotic, it will generally affect both the complement system and platelets to a certain degree. LÄS MER

7. 20. 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
