  1. 1. Direct Demonstration of Influenza Virus and Mycoplasma Pneumoniae in the Respiratory Tract

    Författare :Anna Nilsson; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polymeras chain reaction; influenza virus; Mycoplasma pneumoniae; diagnosis; respiratory tract infection; sample site; serial samples;

    Sammanfattning : Diagnostic tests based on nucleic acid amplification have become available for Mycoplasma pneumoniae (MP) and influenza viruses. Here, an MP PCR test detected 100% of infections during the first three symptomatic weeks, whereas classical serology detected 21% week 1, 56% week 2, and 100% week 3. LÄS MER

  3. 2. Structural studies of ba3-type cytochrome c oxidase using serial crystallography and X-ray absorption spectroscopy

    Författare :Doris Zoric; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ba3-type cytochrome c oxidase; structural biology; X-rays; serial X-ray crystallography; X-ray absorption spectroscopy; enzyme reaction dynamics;

    Sammanfattning : Cytochrome c oxidase (CcO) catalyses the reduction of molecular oxygen to water while the energy released in this process is used transport protons “up-hill” across an energy transducing biological membrane, creating a proton-motive force for ATP synthesis. Given its key role in energy transduction in organisms, proton pumping has been extensively studied across species. LÄS MER
