1. 1. 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

3. 2. 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

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 pressure in advanced age : with focus on epidemiology, cognitive impairment and mortality

   Författare :Lena Molander; Hugo Lövheim; Yngve Gustafson; Miia Kivipelto; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood pressure; hypertension; very old; mortality; epidemiology; cognitive impairment; dementia; Blodtryck; hypertoni; mycket gamla; dödlighet; epidemiologi; demens; Geriatrics and medical gerontology; Geriatrik och medicinsk gerontologi; geriatrik; Geriatrics; Epidemiology; epidemiologi;

   Sammanfattning : The general conception is that blood pressure increases with age, but that diastolic blood pressure (DBP) starts decreasing in the elderly. There are, however, indications that systolic blood pressure (SBP) might also decline in advanced age, but further studies are needed to establish whether this is true. LÄS MER

7. 5. Trace Element Analysis with Application to Environmental Pollutants Studies in Vietnam

   Författare :Thi Hong Nguyen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blood; environmental samples; discriminant analysis; ICP-MS; coal mining; hair; EDXRF; microwave digestion; CV-AAS; urine; sample preparation; coal combustion;

   Sammanfattning : In the work presented here the attention has been focused on optimising sample preparation and analytical techniques for trace element determination, analytical quality assurance and environmental applications. Trace element concentrations in various environmental matrices were investigated using Energy Dispersive X-ray Fluorescence (EDXRF), Inductively Coupled Plasma Mass Spectro-metry (ICP-MS) and Cold Vapour Atomic Absorption Spectrometry (CV-AAS).
