The aim of this thesis was to empirically and methodologically investigate health related quality of life (HRQoL) among persons 65 years or older with chronic heart failure. The design was cross-sectional and the sample was recruited from a southeast region of Sweden. The sample included 357 respondents in Paper I, II and IV and 349 respondents in Paper III. For all respondents the mean age was 79

A group of normal subjects (n = 17) was compared with groups of patients with a diagnosis of vestibular neuritis (n = 18), and acoustic neuromas (n = 35). Fisher linear discriminant analysis was applied to distinguish clusters of parameters characteristic for each disease. Hence it was possible to distinguish the vestibular neuritis patients from the normal group with statistical significance (p <

A runtime system for implementation of image processing operations is presented. It is designed for working in a flexible and distributed environment related to the software architecture of a newly developed UAV system. The software architecture can be characterized at a coarse scale as a layered system, with a deliberative layer at the top, a reactive layer in the middle, and a processing layer a

Background: Working life is an important arena in most people's lives, and the working line concept is important for the development of welfare in a society. For young people, the period before permanent establishment in working life has become longer during the last two decades. Knowledge about attitudes towards work can help us to understand young people's transition to the labour market. Adoles

Pelvic pain (acute or chronic) is a common symptom in women of all ages. Ultrasonography is the least invasive investigative tool available to the clinician. Transvaginal probes produce high-resolution images of the pelvic organs, providing reliable and reproducible information without the need for a full bladder. Common gynaecological pathology involving the uterus, Fallopian tube and/or the ovar

Popular Abstract in Swedish I avhandlingen studeras Matrix MetalloProteinase-26 (MMP-26) och Tissue Inhibitor of MetalloProteinases-4 (TIMP-4) i normalt, hyperplastiskt och malignt endometrium. Just detta protease/hämmarpar kan potentiellt vara av mycket stort intresse vid implantationsprocessen. Trofoblastvävnad från såväl humant som murint embryo producerar proMMP-9. Aktivt MMP-9 (Gelatinase B)The aim of the thesis was to study matrix metalloproteinase-26 (MMP-26) and tissue inhibitor of metalloproteinases-4 (TIMP-4) in normal, hyperplastic, and malignant endometrium. Most importantnly, both these molecules may be ivolved in the implantation process. Trophoblast tissue from human as well as mouse embryos produces pro-MMP-9. Active MMP-9 (gelatinase B) is a proteolytic enzyme with a bro

The effect of the extent of electron conjugation on the primary photophysics in semiconducting polymers is reported. A rapid depolarization of photoluminescence and transient absorption, which indicates a reorientation of the transition dipole moment by ~30° on a sub-100 fs time scale, is observed in the fully conjugated polymer poly[2-(2'-ethylhexyloxy)-5-methoxy-1,4-phenylenevinylene] (MEH-PPV).

This study investigated whether the relation between implicit and explicit homonegativity measures is affected by self-presentation concerns, since previous research in this area has been inconclusive. In Experiment 1, 70 high-school students made evaluative ratings of pictures of homosexual and heterosexual couples. Self-presentation was manipulated by either instructing participants that the stu

Several microbial pathogens have been reported to interact with glycosaminoglycans (GAGs) on cell surfaces and in the extracellular matrix. Here we demonstrate that M protein, a major surface-expressed virulence factor of the human bacterial pathogen, Streptococcus pyogenes, mediates binding to various forms of GAGs. Hence, S. pyogenes strains expressing a large number of different types of M prot

Study objectives: In 1996, researchers in Sweden initiated a collaborative randomized study comparing lung volume reduction surgery (LVRS) and physical training with physical training alone. The primary end point was health status; secondary end points included survival and physiologic measurements. Design: After an initial 6-week physical training program, researchers' patients were randomized to

Gonococci that bind the coinhibitory receptor CEACAM1 appear to down-regulate the activation and proliferation of CD4+ T cells. Such infection-induced immunosuppression helps explain why there is little specific immune response associated with gonococcal disease.

It is common to use activities of daily living (ADL) rating scales to identify the impact of health problems such as diseases, impaired eyesight or hearing on daily life. However, for various reasons people with health problems might feel hindered in daily life before limitations in ability to perform ADL have occurred. In addition, there is sparse knowledge of what makes people feel hindered by h
