  1. 21. NA transmembrane domain : Amphiphilic drift to accommodate two functions

    Författare :Johan Nordholm; Robert Daniels; Ervin Fodor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; influenza; IAV; neuraminidase; NA; transmembrane domain; TMD; secretory protein; ER-targeting sequence; ER-targeting sequence coding region; protein regulation; NS1; GALLEX; Biochemistry; biokemi;

    Sammanfattning : Neuraminidase (NA) is one of two major antigens on the surface of influenza A viruses. It is comprised of a single N-terminal transmembrane domain (TMD), a stalk domain, and a C-terminal enzymatic head domain that cleaves sialic acid, most notably to release new particles from the host cell surface.

  2. 22. On the epidemiology, clinical presentation and transmission of respiratory viral infections

    Författare :Nicklas Sundell; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; respiratory viruses; measles; influenza; epidemiology; meteorological factors; real-time PCR; viral transmission; lower respiratory tract infection;

    Sammanfattning : Respiratory viral infections encompass a large heterogenous group of pathogens that constitute a major burden of disease globally. The various routes of transmission including airborne spread make them difficult to control. LÄS MER

  3. 23. Harnessing the immunoregulatory capacity of single-stranded oligonucleotides to modulate innate immunity

    Författare :Aleksandra Dondalska; Anna-Lena Spetz; Jenny Hallgren Martinsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single-stranded oligonucleotides; Toll-like receptors; influenza; respiratory syncytial virus; dendritic cell; mast cell; virus infection; inflammation; itch; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : As the first line of defense, the innate immune system is exceptionally efficacious against invading pathogens but must be tightly regulated to avoid immune-related pathogenesis. Accordingly, the innate immune system recognizes highly conserved components associated with infections and damaged cells using a limited number of pattern-recognition receptors (PRRs), which are differentially expressed across cell types.

  4. 24. Monitoring anti-infectives and antibiotic resistance genes : with focus on analytical method development, effects of antibiotics and national perspectives

    Författare :Ghazanfar Ali Khan; Jerker Fick; Klaus Kümmerer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; method development; on-line solid phase extraction liquid chromatography mass spectrometry SPE LC-MS MS ; antibiotics; anti-infectives; constructed wetlands CWs ; denatured gradient gel electrophoresis DGGE ; percentage removal efficiency PRE ; shannon index; antibiotic resistance genes ARGs ; real-time polymerase chain reaction RT-PCR ; drug formulation facilities DFF ; wastewater; epidemiology; pandemic; influenza; compliance;

    Sammanfattning : Antibiotics are biologically active and are globally used in humans and animal medicine for treatment and in sub-therapeutic amounts as growth promoters in animal husbandry, aquaculture and agriculture. After excretion, inappropriate disposal and discharge from drug production facilities they enter into water bodies either as intact drugs, metabolites or transformed products. LÄS MER

  5. 25. Liposomes for mucosal vaccine delivery: physicochemical characterization and biological application

    Författare :Karin Norling; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanoparticles; vaccine carriers; antigen presentation; dendritic cells; surface plasmon resonance; flow cytometry; liposomes; cellular uptake; fluorescence microscopy; influenza;

    Sammanfattning : Liposomes are attractive vaccine carriers due to their potential to act as adjuvants, and to the fact that their composition and characteristics are virtually endlessly customizable. However, the precise physicochemical profile of an ideal carrier liposome for mucosal vaccines is still widely unknown, and how different properties affect key steps in the acquisition of protective immunity remains to be elucidated.
