21. Modeling DNA Damage
Sammanfattning : In this thesis methods of computational chemistry have been used to examine DNA damaging processes initiated by ionizing radiation, free radicals, or Low-Energy Electrons (LEE). The computational chemistry method based on quantum mechanics that has been mainly used here is the Density Functional Theory (DFT). LÄS MER
22. Effect of Ischaemia-Reperfusion on Rabbit Kidney and Human Brain
Sammanfattning : Free radicals are produced in various organs at ischaemia-reperfusion. The final stage in radical damage is lipid peroxidation. We have demonstrated previously that a lipid-soluble antioxidant improves restoration of bioenergetics in rabbit kidneys after ischaemia, as reflected in 31P spectrometry. LÄS MER
23. Inflammation in experimental neonatal brain injury and in a clinical study of preterm birth; involvement of galectin-3 and free radical formation
Sammanfattning : Introduction; Intrauterine infection/inflammation is associated with preterm delivery (PTD) and severe neonatal morbidity. Inflammation is also important in the secondary neurotoxic cascade leading to perinatal brain injury. LÄS MER
24. Effects of Th-1 and Th-2 Cytokines and Reactive Oxygen Species on Normal Human Bronchial Epithelial Cells
Sammanfattning : Epithelial damage and shedding of the epithelium are common observations in many airway diseases such as asthma, Sjögren’s syndrome, chronic obstructive pulmonary disease and cystic fibrosis. The ability of the cells to attach to each other and/or to the matrix seems to be altered. LÄS MER
25. Physical and Chemical Processes in the Formation of Biogenic secondary Organic Aerosols
Sammanfattning : Vegetation emits a vast number of biogenic volatile organic compounds (BVOC). In the atmosphere they are oxidised, predominantly by O3, OH radicals or NO3 radicals, depending e.g. on chemical structure. LÄS MER
