The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. In this thesis I investigate both the direc
A new method, where a tendon segment – a tendon autograft – was used as graft material for peripheral nerve reconstruction, was developed. Defects, 10-15 mm long, in rat sciatic nerves were bridged by various modifications of tendons. A piece of an intact tendon and a tendon, that had been teased into a membrane and then rolled to form a loose “collagen roll”, supported axonal regeneration over a
This thesis is based on data from a large glaucoma screening, comprising 32, 918 elderly citizens of Malmö and data from retrospective analysis of glaucoma patients’ charts from the Eye Department of Malmö University Hospital. The definition of glaucoma was based on reproducible visual field defects and/or glaucomatous optic nerve head damage in both groups. In paper I, including screened individ
Since soluble fibre in the form of the cereal beta-glucans found in oats and barley has been shown to have a positive effect on lipid and glucose metabolism, people at risk of developing cardiovascular diseases or diabetes might benefit from that a variety of palatable food products containing beta-glucans being available to them. The aim of the papers presented in the thesis was to evaluate the m
Urinary tract infections (UTI) are among the most common human infections, and febrile UTI with bacteremia the most severe form. The relation between bacteria and host decides disease severity. The dominating uropathogen is Escherichia coli (E. coli). P fimbriae are the virulence factor of E. coli most clearly associated to severe disease. P fimbriated E. coli predominated in bacteremic febrile UT
The book is a comprehensive Danish grammar describing modern, written Danish. It comprises morphology, word classes, syntax, and semantics. Corpus based listings of functional words. Index comprising 800 grammatical terms.
For a long time microorganisms were assumed to have unlimited dispersal due to their small size and high cell numbers. Most microbial species can be transported by water currents, in water droplets by wind and attached to other organisms. Environmental conditions alone were supposed to affect the distribution of species and the community composition. Therefore, microorganisms were assumed to consi
Over the last decades the ongoing work in the fields of Lab-on-a-Chip and Micro-Total-Analysis-Systems has led to the discovery of new or improved ways to handle and analyse small volumes of biofluids and complex biosuspensions. The benefits of working on the microscale include: miniaturization of the analysis systems with less need for large sample volumes; temporal and spatial control of suspend
The article dicusses the etymology of three preliterary Common Nordic prepositions: till 'to', hos 'at', från 'from'. Phonological, morphological, syntactic and semantic aspects are taken into account to explain the grammaticalization processes.
Critical infrastructures provide indispensable services to society and extensive disruption of these give rise to large societal consequences. Most risk-related studies of critical infrastructures, however, focus rather narrowly on the direct consequences, e.g. expressed by services not supplied or cost of nonsupplied services. Although these measures might serve as a proxy for the direct societal
Median micturition volume decreased early after partial outlet obstruction, 24 hrs total obstruction and hemidenervation. Degeneration release of transmitter may explain this, assuming that bladder wall distension causes nerve degeneration. Micturition pressure decreased simultaneously in the partially denervated and 24 hrs obstructed groups, probably due to the reduced number of functionally inta
The thesis examine the problem concerning the responsibility of listed companies for false and misleading information in the secondary segments of the stock market.
Det här är en rapport från ett Vinnovafinansierat projekt där syftet har varit att empiriskt visa på de största utmaningarna för ett ökat tillgängliggörande av öppna data och att visa på möjliga vägar fram. Gemensamt för alla öppna data är att det är maskinläsbara datamängder som kan vidareutnyttjas av vem som helst. Det finns framförallt två aspekter man behöver förhålla sig till när man pratar
The aim was to study the epidemiology of chronic pain (> 3 months duration) and factors associated to pain prevalence, prognosis, health care and medication in a general population. A cross-sectional mailed survey to a random population sample (n = 1806) was followed by a clinical examination and a prospective study of three selected groups. Pain related diagnoses from primary health care was moni
Almost all northern forest tree species live in symbioses with ectomycorrhizal fungi (EMF). The trees allocate up to half of the photoassimilated carbon (C) through the roots to EMF. In return EMF deliver nutrients from both inorganic and organic sources in the soil, as well as water. Most of the nutrients trees need are assimilated through EMF, which thus play a potentially important role in reta
Body dimensions of 2,936 newborns with cleft lip/palate (CLP) were compared with 2,031,140 singleton newborns between 1973 to 1992. The risk of cleft development was found to be associated with intra-uterine growth retardation - the more severe the cleft, the stronger the association. As digital photography is being increasingly applied in clinical medicine, we devised a computer software program
Calcium homeostasis involves mainly the interaction of PTH, vitamin D and CT. The stomach may be important for calcium homeostasis. Gastric acid is thought to mobilize calcium from the diet, thereby facilitating the absorption of calcium in the small intestines. In the rat, gastrectomy rapidly reduces the calcium content, the density and the trabecular volume of the bone. The gastrectomy-evoked bo
Brain ischemia is a major cause of death and morbidity in the industrialized countries. It is mainly caused by stroke, but may also be the consequence of successful cardiopulmonary resuscitation in victims of cardiac arrest, known as transient global ischemia. Although extensive effort in the field of brain research using experimental rodent models, no neuroprotective treatments are at present ava
