  1. 6. Enzymatic metal-chelation by porphyrins

    Författare :Andreas Hansson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tetrapyrrole; Plant biochemistry; Växtbiokemi; MIDAS; metallation; magnesium chelatase; integrin; heme; ferrochelatase; chlorophyll; barley; AAA ; ATPase;

    Sammanfattning : This thesis deals with the structure and function of two different enzymes, ferrochelatase and magnesium chelatase, that catalyse similar reactions. When this work started, a three-dimensional model of ferrochelatase existed. Much was known about the enzyme, but some details remained unclear. LÄS MER

  3. 7. Abdominal Aortic Aneurysm, aspects on diagnosis and treatment

    Författare :Kristian Smidfelt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Abdominal Aortic Aneurysm; Screening; EVAR; AAA; Mortality; rAAA; Misdiagnosis; ruptured Abdominal Aortic Aneurysm; open abdomen; open repair; abdominal compartment syndrome; vacuum assisted closure;

    Sammanfattning : Background An abdominal aortic aneurysm (AAA) is an abnormal widening of the aorta with a risk of rupture if it grows to a large diameter. Rupture is associated with massive bleeding and a poor prognosis for survival. LÄS MER

  4. 8. Clinical Aspects on Chimney Stent Graft Technique in Endovascular Repair of the Aorta

    Författare :Adel BinJabr; Vaskulära sjukdomar - kliniska studier; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chimney stent graft; chimney graft; chimney graft technique; snorkel technique; endovascular aortic repair; thoracic endovascular aortic repair; endoleak; patency; rupture; urgent; stent-graft; stent; graft; aorta; computed tomography; ultrasound; stenosis; EVAR; TEVAR; CTA; MRI; AAA; TAAA; supraaortic; visceral; aneurysm; dissection; mycotic infection; stent-graft infection; follow-up; endovascular complication; sandwich technique; periscope graft; periscope graft technique.;

    Sammanfattning : Introduction: Open repair of the aorta carries a high risk for morbidity and mortality especially in the elderly population and in patients unfit for major surgery. Endovascular aortic repair is safe, durable and effective when there is adequate proximal and distal sealing zone for the aortic stent graft. LÄS MER

  5. 9. Assembly and Function of Nitric Oxide Reductase from Paracoccus denitrificans

    Författare :Maximilian Kahle; Pia Ädelroth; Hans-Georg Koch; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-heme iron; cofactor; heme-copper oxidase; AAA ; cNOR; chaperone; metal ion insertion; MoxR; nor accessory genes; FeB; liposomes; membrane mimetics; nanodiscs; reconstitution; enzymatic mechanism; NO reduction; O2 reduction; Biochemistry; biokemi;

    Sammanfattning : Bacterial denitrification is a part of the global nitrogen cycle and comprises the stepwise reduction of nitrate to molecular nitrogen, which is released to the atmosphere. Cytochrome c-dependent nitric oxide reductase (cNOR) from Paracoccus (P.) denitrificans catalyzes the reduction of nitric oxide to nitrous oxide and water. LÄS MER

  7. 10. Deciphering control of Mechano-Transcription Activators of σ54-RNA polymerase

    Författare :Henrik Seibt; Victoria Shingler; Uwe H. Sauer; Ray Dixon; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transcriptional regulation; P. putida; V. cholerae; AAA ; bEBP; B-linker; DmpR; Phenol catabolism; VCA0117; Type VI secretion; molekylärbiologi; Molecular Biology;

    Sammanfattning : To survive and proliferate, bacteria have to respond to a plethora of fluctuating signals within their habitats. Transcriptional control is one crucial entry point for such signal-responsive adaption responses. LÄS MER
