The anatomy, function and plasticity of the primary olfactory centre, the antennal lobe (AL), of the desert locust Schistocerca gregaria was investigated using a number of neuroanatomical and neurophysiological methods. Anatomical characterisation of the AL in a number of orthopteran species made it possible to deduce a model concerning the evolution of microglomeruli. These neuropil structures, c
Hypoglycaemia is an acute complication to insulin-treatment in type 1 diabetes mellitus, which affects many physiological parameters, deteriorates the cognitive function, and may lead to death. The aim of this thesis was to study nerve function, cognitive function and cerebral blood flow during and after hypoglycaemia in healthy subjects and to study certain aspects of a fall in blood glucose in p
Huntington's disease (HD) is a hereditary neurodegenerative disorder presenting with chorea, dementia and extensive striatal neuronal death. The mechanism through which the widely expressed mutant huntingtin mediates striatal neurotoxicity is unknown. Excitotoxicity, i.e. calcium-dependent cell death induced by activation of NMDA receptors, has been hypothesized to play an important role in HD. Ou
The DIRECT (Diabetes Research on Patient Stratification) Study is part of a European Union Framework 7 Innovative Medicines Initiative project, a joint undertaking between four industry and 21 academic partners throughout Europe. The Consortium aims to discover and validate biomarkers that: (1) predict the rate of glycaemic deterioration before and after type 2 diabetes onset; (2) predict the resp
Autoantibodies (A) against Neuropeptide Y (NPY), was reported in 9% newly diagnosed type 1 diabetes (T1D) patients. A single nucleotide polymorphism (SNP) at rs16139 (T1128C) within the NPY-gene identified an amino acid substitution from leucine (L) to proline (P) (L7P) associated with both glucose tolerance and type 2 diabetes. We aimed to determine: (i) the influence of autoantibodies to leucine
In a world with imperfectly integrated national capital markets the cost of funds is, in general, different across markets. If individual countries, by mutual agreement, or forced by factors outside their control, embark on a process of deregulation and financial integration, the spread in the cost of funds across markets will narrow. Some types of impediments, such as explicit capital controls, w
Memory in prehistoric societies may be observed in the repetitive use of places and artefacts. The fact that sites were used for different purposes with intervals of several centuries indicates that information about land use, e.g. for ritual purposes, was retained for several generations. In some cases the use of old cemeteries and the copying of old ornaments might act as a link to past times wi
The major part of this thesis deals with the similarities and differences in some biophysical properties of apolipoprotein A-I (apo A-I) and the molecular variant apolipoprotein A-IMilano (apo A-IM), and the influence on lipid binding. A model compound partitioning study has also been performed. Methods that have been utilised are CD spectroscopy, calorimetry both isothermal
Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. Ectomycorrhizal fungi form mutualistic interactions with the roots of woody plants, including almost all boreal and temperate forests
All clients admitted to ten pilot case management services for individuals with severe mental illness during 1995 and up to 1996-09-30 were invited to participate in the present study. A total of 176 clients were included. The clients were in all services assessed at admission and at an 18 months follow-up with regard to needs of care, psychosocial functioning. Use of health care and social servic
Dwarf males occur in many unrelated groups of organisms. Among land plants they are unique to mosses. Moss dwarf males originate from male spores that land and germinate on the female where their final size is restricted to a few mm. Fertilization in mosses occur over short distances with swimming spermatozoids. Having the males growing as tiny epiphytes on the females facilitates fertilization, a
Normal urine storage and bladder emptying are controlled by the central (CNS) as well as the peripheral nervous system. Dysfunction of these mechanisms can lead to urinary incontinence. Urinary tract dysfunctions have symptomatically been treated mainly with drugs acting peripherally. However, in the CNS, drug targets for pharmacological intervention may be found. The present study deals with effe
During recent years we have seen several large-scale crises. The 9/11 terror attacks, tsunamis, storms, floods and bombings have all been unpredictable and caused a great deal of damage. One common factor in these crises has been the need for information and one important source of information is usually web sites. In this work three new sets of web server access logs are presented and analyzed, o
Major climate and ecological changes affect the world’s oceans leading to a number of responses including increasing water temperatures, changing weather patterns, shrinking ice-sheets, temperature-driven shifts in marine species ranges, biodiversity loss and bleaching of coral reefs. In addition, ocean pH is falling, a process known as ocean acidification (OA). The root cause of OA lies in human
