2. Micronutrients in cereal crops : impact of nutrient management and soil properties
Sammanfattning : Seven elements essential for plants are defined as micronutrients: boron (B), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni) and zinc (Zn). Deficiency of these nutrients can cause yield losses in crops and impaired crop quality. LÄS MER
3. Developmental patterns in the Nostoc-Gunnera symbiosis
Sammanfattning : Gunneraceae is an angiosperm family comprising about 60 species scattered in the southern hemisphere. All members of the family develop a nitrogen-fixing symbiosis with intracellularly located Nostoc. The aim of the present study was to characterize the symbiosis, structurally and physiologically, with emphasis on G. magellanica and G. LÄS MER
4. Inducible nitric oxide synthase in experimental urinary tract infection
Sammanfattning : Urinary tract infection (UTI) is among the most common bacterial infections in humans and the majority are caused by Escherichia coli (E. coli). Abundant evidence indicates that nitric oxide (NO) produced by the inducible NO synthase (iNOS) plays an important role in host defense against infection. LÄS MER
5. Potential mechanisms for acute health effects and lung retention of inhaled particles of different origin
Sammanfattning : Background: Environmental particle exposure is known to have negative health effects. There is limited knowledge about how size and origin of particles influence these effects. There is also little known regarding the fate of ultrafine particles (particles in nanosize;< 100 nanometers in diameter) after being inhaled. LÄS MER
