1. 1. Blood Culture Negative Endocarditis

   Författare :Maria Werner; Göteborgs universitet; []
   Nyckelord :Infective endocarditis IE ; Blood culture negative endocarditis CNE ; Blood culture; Diagnosis; Mortality; Bartonella; Coxiella burnetii; Chlamydophila pneumoniae; Prevalence; Aminoglycoside;

   Sammanfattning : The lethal disease infective endocarditis (IE) is caused by microorganisms that attack heart valves. Early diagnosis and identification of the causative agents are important for the choice of treatment. Optimal treatment may be difficult to achieve if blood culture negative endocarditis (CNE) is present. LÄS MER

3. 2. Clinical applications of acoustophoresis in blood based diagnostics

   Författare :Klara Petersson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Acoustofluidics; Ultrasound; Microfluidics; Blood; Blood Separation; Blood plasma; Lab-on-a-chip; Point-of-care; Blood diagnostics;

   Sammanfattning : In this thesis, acoustofluidics has been used to process blood samples as a sample preparation step prior to biomarker detection. This is often required as the large amount of blood cells otherwise can interfere with the detection method. Acoustofluidics means moving particles or cells with acoustic forces within microfluidic channels. LÄS MER

4. 3. Optimisation of diagnostic PCR a study of PCR inhibitors in blood and sample pretreatment

   Författare :Waleed Abu Al-Soud; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mycology; virology; bacteriology; Microbiology; AmpliTaq Gold; Amplification facilitators; Betaine; Blood culture medium; Blood; BSA; cheese; faeces; gp32; Haemoglobin; Ions; Immunoglobulin G; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : PCR is widely employed as a rapid, sensitive and specific molecular diagnostic technique in clinical diagnosis, environmental investigations and for monitoring biotechnical processes. However, the full potential of diagnostic PCR is limited, in part, by the presence of PCR-inhibitory substances in biological samples. LÄS MER

5. 4. Blood exposure in health care : health care workers' and patients' experiences

   Författare :Ulla-Britt Lymer; Barbro Isaksson; Bengt Richt; Vivi-Anne Sundquist; Linköpings universitet; []
   Nyckelord :Blood-exposure; needle-stick; compliance; universal precautions; balancing; quaIity care; nursing; patients conceptions; grounded theory; phenomenography; MEDICINE; MEDICIN;

   Sammanfattning : The general aim of this thesis was to describe and analyse health care workers' blood-exposure incidents, protective measures, and the motives behind decision making about risks and protective measures. The aim was also to procure knowledge about patients' conceptions about their care, and if precautions taken by the health care workers were included in quaiity care. LÄS MER

7. 5. Assessment of eosinophil degranulation in allergic diseases and experimental models

   Författare :Monika Malm-Erjefält; Avdelningen för klinisk kemi och farmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood; histochemistry; cytochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur; animal morphology; Animal anatomy; Djurs anatomi och morfologi; Haematology; cytoplasmic granules ; Hematologi; Respiratory system; extracellulära vätskor; Andningsorganen; toxikologi; farmaci; farmakognosi; Farmakologi; toxicology; pharmacy; pharmacognosy; Klinisk biologi; Pharmacological sciences; Histology; cell separation ; mice; animal models ; biological marker ; transmission electron microscopy allergy; cell degranulation ; Clinical biology; extracellular fluids; eosinophils;

   Sammanfattning : In allergic disorders, the eosinophilic granulocytes migrate to affected tissues and release granule proteins with cytotoxic, immunoregulatory, and remodeling-promoting properties. Given that degranulation is reflected by a loss in eosinophil granule density of living cells, or by cell membrane rupture and release of intact granules, these morphological changes may represent a biomarker of the allergic disease.
