1. 6. Fungal DNA, Mould, Dampness and Allergens in Schools and Day Care Centers and Respiratory Health

   Författare :Guihong Cai; Dan Norbäck; Christer Janson; Nils Åberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Day care centers; Quantitative PCR; Fungal DNA; Allergens; Indoor environment; Building dampness; Bacteria; Mycotoxins; Respiratory symptoms; Asthma; School environment; Viable moulds; School children; Occupational and Environmental Medicine; Arbets- och miljömedicin;

   Sammanfattning : Day care centers and schools are important environments for children, but few epidemiological studies exist from these environments. Mould, dampness, fungal DNA and allergens levels in these environments and respiratory health effects in school children were investigated in this thesis. LÄS MER

3. 7. Invasive fungal disease in immunocompromised hosts with focus on diagnostics

   Författare :Helena Hammarström; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; invasive fungal disease; diagnosis; 1; 3-β-d-glucan; hematological malignancies; hematopoietic stem cell transplantation; HIV; lung transplant recipients; bronchiolitis obliterans syndrome;

   Sammanfattning : Invasive fungal diseases (IFDs) are severe conditions affecting immunocompromised patients. The primary aim of this thesis was to explore different methods for diagnosis of IFD in different groups of immunocompromised patients. Papers I and II included patients with hematologic disorders.

4. 8. Catalytic and Structural Properties of Heme-containing Fatty Acid Dioxygenases : Similarities of Fungal Dioxygenases and Cyclooxygenases

   Författare :Ulrike Garscha; Ernst Oliw; Per-Johan Jakobsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dioxygenase; prostaglandin H synthase; Gaeumannomyces graminis; Aspergilli; hydroperoxide isomerase; linoleate diol synthase; cytochrome P450; oxylipin; Pharmaceutical pharmacology; Farmaceutisk farmakologi; Farmaceutisk farmakologi; Pharmaceutical Pharmacology;

   Sammanfattning : 7,8-Linoleate diol synthase (7,8-LDS) of the take-all pathogen of wheat, Gaeumannomyces graminis, converts linoleic acid to 8R-hydroperoxyoctadecadienoic acid (8-HPODE) by 8-dioxygenase activity (8-DOX), and further isomerizes the hydroperoxide to 7S,8S-dihydroxyoctadecadienoic acid (7,8-DiHODE) by hydroperoxide isomerase activity. Sequence alignment showed homology to prostaglandin H synthase (PGHS), and both enzymes share structural and catalytic properties. LÄS MER

5. 9. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

   Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

   Sammanfattning : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. LÄS MER

7. 10. Cellulose-fiber-based thermal insulation materials with fungal resistance, improved water resistance and reaction-to-fire properties

   Författare :Chao Zheng; Monica Ek; Dongfang Li; Lars Wågberg; Folke Björk; KTH; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; birch bark; cellulose; reaction-to-fire properties; fungal resistance; thermal insulation; water resistance; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Thermal insulation materials made from natural fibrous materials, such as cellulose fibers, have advantages over others from a sustainability point of view. However, cellulosic materials are generally prone to mold and absorb moisture, and these have negative effects on the insulation properties, the durability of insulation materials, and interior air quality.
