The pro-inflammatory mediator, Leukotriene D4 (LTD4) is a product of arachidonic acid cascade and has been implicated in asthma and inflammatory bowel diseases. Prolonged inflammatory conditions like ulcerative colitis increases the risk for the development of cancer and the factors that induce the chronic immune response remain uncertain. In this context, in the present study, we examined if expo
Boken innehåller 15 artiklar skrivna av Ulf Teleman mellan 1977 och 2011 samt en fullständig bibliografi över hans språkvetenskapliga författarskap (1956-2012).
Transportation fuels from renewable resources such as ethanol are one of the alternatives to ensure energy security and decrease the net emission of carbon dioxide. First-generation ethanol production from sugar- and starch-based raw materials (1G) is today well established in many countries, and the focus of research has thus shifted to the development and demonstration of the production of secon
The efficacy of surgery, physiotherapy or a cervical collar in the treatment of chronic cervicobrachial pain of radicular origin was evaluated in a prospective, randomised study comprising 81 patients of both sexes, 28-64 years of age, referred for possible neurosurgical treatment. After neurological and radiological examination and giving their informed consent, they were randomised to one of the
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
Aggressive lymphoma is a rapidly growing tumour of lymphocyte origin, potentially curable with chemotherapy. In a trial by the Nordic Lymphoma Group, 405 patients with aggressive lymphoma were included, and randomised to receive either the standard chemotherapy regimen, CHOP, or a weekly multidrug regimen, MACOP-B. In this trial, MACOP-B was not superior in terms of response, failure-free or overa
To be in need or to manage is a question open for negotiation. The concept of need is depending on the interpretation of the one who defines it. When a person is a victim of crime, her needs' can be defined from many different perspectives. Organisations for victim support are becoming more and more established. These organisations are founded on ideas of "need", the organisations are "needed" bec
The process of speciation is a cornerstone in evolutionary biology. In Darwin’s On the Origin of Species, he described how he imagined that a new species would evolve to fill an empty niche. This focus on ecology shifted with Mayr towards the importance of isolation, and for many decades the geographic modes of speciation were debated. Speciation in sympatry, i.e. without any isolation between the
The importance of early detection of brain changes during ageing has been recognised. Single photon emission computed tomography (SPECT) is a method used for estimation of cerebral blood flow (CBF) in clinical work and in research. The aim of thesis was to study CBF in demented and non-demented elderly persons with special reference to blood pressure changes. Elderly women with senile dementia of
Svensk universitetsgrammatik för nybörjare presenterar på ett resonerande sätt grunderna i svensk grammatik. Utgångspunkten är den traditionella grammatiken, men hänsyn tas också till nyare landvinningar inom den moderna grammatikforskningen. Boken riktar sig i första hand till studerande i ämnena svenska och nordiska språk vid universitet och hörskolor. Den innehåller rikligt med exempel och är u
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
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
Varför vet alla med svenska som modersmål att det heter "en intressant bok" och inte "en bok intressant"? Det beror på vår fantastiska, inre grammatik. Insikten om hur man uttrycker sig på modersmålet är något som barnet lär sig under de första levnadsåren, och redan i treårsåldern behärskar barnet huvuddelen av de omedvetna regler och principer som styr hur meningarna i modersmålet är uppbyggda.
