  1. 31. Genital human papillomaviruses. Studies of their occurrence, type spectrum and expression

    Författare :Ola Forslund; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA expression; microwell; HPV 70; type determination; CIN; quantification; urine; multifocal infections; hybridization; PCR; HPV; human papillomavirus; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The occurrence of genital human papillomavirus infection was determined in different categories of patients by means of PCR. In high proportion of young women attending an adolescent clinic, the presence of HPV DNA was demonstrated in simultaneously urethral and cervical samples, suggesting that genital HPV infections are often multifocal.

  2. 32. Combined structural methods to characterize an oligomeric small heat shock protein Hsp21

    Författare :Gudrun Rutsdottir; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small heat shock proteins; chaperones; crosslinking mass spectrometry; Stable isotope labeling; quantification; small angle X-ray scattering; cryo-electron microscopy; combined structural methods; plant stress;

    Sammanfattning : Small heat shock proteins (sHsps) are found in all organisms and evolved early in the history of life, prior to the divergence of the three domains of life (Archaea, Bacteria, and Eukarya). Their malfunction is connected to several different diseases in humans, such as Alzheimer’s and Parkinson’s disease. LÄS MER

  3. 33. New single particle methods for detection and characterization of nanoparticles in environmental samples

    Författare :Jani Tuoriniemi; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Detection; Quantification; Metrology; Trace particle;

    Sammanfattning : Nanoparticles (NP) are being used in rapidly increasing quantities which has resulted in concerns about possible harmful effects for health and environment. NP are already undergoing similar risk assessment programs as conventional chemicals, and due to their enhanced surface reactivities it has been proposed that the use of NP should be regulated by specific legislation based on particle size.

  4. 34. Methods for quantitative analysis of myocardial perfusion SPECT : validated with magnetic resonance imaging, phantom studies and expert readers

    Författare :Helen Fransson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Segmentation; Quantification; Spline; Image registration; Cardiac image analysis; Myocardial perfusion SPECT;

    Sammanfattning : In this thesis, methods for automated analysis of myocardial perfusion single photon emission computer tomography (myocardial perfusion SPECT, MPS) images have been successfully developed and evaluated. MPS images show the perfusion of the myocardium and are used for diagnosing patients with suspected ischemic heart disease. LÄS MER

  5. 35. Analysis of plant growth regulating substances

    Författare :Barbro Andersson; Bo Jansson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant regulators; phytohormones; pine; spruce; anther; abscisic acid; 3-indoleacetic acid; gibberellin Ag; N- 3-indoleacetyl -aspartic acid; dichlorophene; Amberlite XAD-7; identification; quantification; GC; HPLC; GC-MS; GC-MID; Hormoner;

    Sammanfattning : Natural plant growth regulators (phytohormones) are a group of organic compounds which, in very small amounts, act as regulators of physiological processes in plants.Methods were developed for the analysis of phytohormones in samples from Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris (L. LÄS MER
