1. Delayed Cell Death after Traumatic Brain Injury : Role of Reactive Oxygen Species
Sammanfattning : Traumatic brain injury (TBI) is a leading cause of death and disability TBI survivors often suffer from severe disturbances of cognition, memory and emotions. Improving the treatment is of great importance, but as of yet no specific neuroprotective treatment has been found. LÄS MER
2. Diabetes-induced Alterations in Renal Microcirculation and Metabolism
Sammanfattning : Diabetes-induced renal complications, i.e. diabetes nephropathy, are a major cause of morbidity and mortality. The exact mechanism mediating the negative influence of hyperglycaemia on renal function is unclear, although several hypotheses have been postulated. LÄS MER
3. Radical aspects on arthritis : the role of neutrophil generation of nitric oxide and superoxide in inflammatory conditions
Sammanfattning : The polymorphonuclear neutrophil granulocytes (neutrophils) are gaining renewed interest regarding their involvement in chronic inflammatory disorders, including rheumatoid arthritis (RA). Besides phagocytic and destructive capabilities, neutrophils have regulatory roles, e.g. by influencing responses from dendritic cells and lymphocytes. LÄS MER
4. Surface reactions on metallic nanoparticles : Ligand adsorption, metal release, and reactive oxygen species generation
Sammanfattning : Humans are exposed daily to metallic nanoparticles (Me NPs) from multiple sources which can have both natural and anthropogenic origins. Such exposures take place via different routes including inhalation and skin contact and may result in adverse health effects. LÄS MER
5. Redox effects on neutrophils in wound healing conducted by wound dressings and hyperbaric oxygen
Sammanfattning : The increased influx of neutrophils into chronic wounds results in increased production of reactive oxygen species (ROS), nitric oxide (NO) and lipid peroxidation products (LPP), as well as a ROS-induced increase in protease levels. The NO and LPP impair the respiratory burst response of the neutrophils and reduce their capacity to kill bacteria and digest debris. LÄS MER
