2. 1. Decompression strain during long-duration, high-altitude exposures : Effects of intermittent excursions to moderate altitude and inspired fractions of oxygen

   Author : Rickard Ånell; Ola Eiken; Mikael Gennser; Mikael Grönkvist; Ole Hyldegaard; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Teknik och hälsa; Technology and Health;

   Abstract : Today´s tactical demands and new technical solutions in fighter aircraft entail longer exposure periods at higher altitudes than before. A low cabin pressure protects pilots from pulmonary barotrauma in case of a sudden loss of cabin pressure, however it can also generate a supersaturation of nitrogen (N2) in the tissues, increasing the risks of bubble formation and decompression sickness (DCS).

4. 2. Surface reactions on metallic nanoparticles : Ligand adsorption, metal release, and reactive oxygen species generation

   Author : Amanda Kessler; Inger Odnevall; Tommy Nylander; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metallic nanoparticles; ROS; reactive oxygen species; metal release; ligand adsorption; corrosion; Fenton like Haber Weiss reactions; metalliska nanopartiklar; ROS; reaktiva syreradikaler; metallfrisättning; adsorption; korrosion; Fenton lika Haber Weiss reaktioner; Kemi; Chemistry;

   Abstract : 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. READ MORE

5. 3. Perinatal Risk Factors for Childhood Leukemia

   Author : Estelle Naumburg; Eleni Petridou; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; Childhood leukemia; infant leukemia; leukemia epidemiology; supplementary oxygen; perinatal risk factors; perinatal infection; prenatal ultrasound; prenatal x-ray; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

   Abstract : The aim of the studies described in this thesis was to assess the association between certain perinatal factors and the risk of childhood lymphatic and myeloid leukemia and infant leukemia. The five studies presented were all conducted in Sweden as population-based case-control studies. READ MORE

6. 4. Genetic vulnerability, environmental exposures and neurodevelopmental disorders : clinical insights and in-vitro consequences

   Author : Abishek Arora; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : An understanding of how different genetic backgrounds and environmental exposures interact and contribute to diverse medical conditions like neurodevelopmental disorders (NDDs), is key to better health outcomes. A considerable overlap exists in the underlying genetics and physiology, often leading to their co-diagnoses. READ MORE

7. 5. Causes and treatment of chronic respiratory failure : experience of a national register

   Author : Torbjörn Gustafson; Kerstin Ström; Karl Franklin; Kjell Torén; Kurt Boman; Leif Bjermer; Umeå universitet; []
   Keywords : Internal medicine; Invärtesmedicin; chronic obstructive pulmonary disease; pulmonary fibrosis; kyphoscoliosis; respiratory failure; sex; smoking; occupation; survival; long-term oxygen therapy; mechanical ventilation; lungmedicin; Lung Medicine;

   Abstract : Long-term oxygen therapy (LTOT) or home mechanical ventilation (HMV) can improve survival time in chronic respiratory failure. A national quality register could be an aid to identifying risk markers and optimizing therapy for respiratory failure. READ MORE
