The ability to measure and understand heat flow in nanowire composites is crucial for applications ranging from high-speed electronics to thermoelectrics. Here we demonstrate the measurement of the thermal conductance of nanowire composites consisting of regular arrays of InAs nanowires embedded in PMMA using time-domain thermoreflectance (TDTR). On the basis of a proposed model for heat flow in t
The early clinical trials using fetal ventral mesencephalic (VM) allografts in Parkinson's disease (PD) patients have shown efficacy (albeit not in all cases) and have paved the way for further development of cell replacement therapy strategies in PD. The preclinical work that led to these clinical trials used allografts of fetal VM tissue placed into 6-OHDA lesioned rats, while the patients recei
Migration to Next Generation Internet architectures poses new challenges for network operators in planning core networks and calls for efficient network planning and optimization tools. Optimization models underlying such tools are developed in this thesis. We study a number of single and two-layer core network design problems defined as mathematical programmes, focusing on fair bandwidth allocati
Cell-based therapies are emerging as new promising treatments in stroke. However, their functional mechanism and therapeutic potential during early infarct maturation has so far received little attention. Here, we asked if cell-based delivery of the interleukin-1 receptor antagonist (IL-1Ra), a known neuroprotectant in stroke, can promote neuroprotection, by modulating the detrimental inflammatory
Popular Abstract in Swedish För att ett transplanterat organ ska accepteras av mottagaren behövs immunhämmande läkemedel. Dessa läkemedel dämpar immunförsvaret och förhindrar avstötning av det transplanterade organet. Immunförsvaret har olika sätt att angripa organet, som det uppfattar som kropps-främmande. Idag används olika läkemedel i kombination som behandling mot avstötning. Tyvärr är dessa mTransplantation of vital organs is today a widely used treatment when failure of the organ is a fact. To prevent rejection immunosuppresive treatment must be maintained lifelong, unless transplantation is perfomed between identical twins. Many immunosuppresive agents introduced in clinical practice have been benificial in improving graft survival rates, but adverse effects remains a huge problem t
OBJECTIVE: The aim of this study was to design a trial that could evaluate the effect of acceptance and commitment therapy as a group-intervention for multiple sclerosis patients with psychological distress. DESIGN: Randomized controlled trial with assessment at pretreatment, end of treatment, and at 3-month follow-up. SUBJECTS: Multiple sclerosis outpatients with elevated symptoms of anxiety and/
When host species colonize new areas, the parasite assemblage infecting the hosts might change, with some parasite species being lost and others newly acquired. These changes would likely lead to novel selective forces on both host and its parasites. We investigated the avian blood parasites in the passerine bird community on the mid-Atlantic island of Sao Miguel, Azores, a bird community originat
Popular Abstract in Swedish Stroke är en sjukdom som främst drabbar äldre och är den största anledningen till att människor får olika slags handikapp såsom förlamning och afasi. Det finns ännu ingen effektiv behandling för att lindra symtom och lidande efter en stroke, förutom rehabilitering, och därför kostar stroke samhället enormt mycket pengar. Befolkningen blir allt äldre, vilket även medför Cell replacement by neural transplantation can, in animal models of neurodegenerative diseases, reconstruct damaged brain circuitry. In the clinical situation, the graft material used for cell therapy must, most likely, be of human origin. The human fetal brain is one potential source of neural stem cells (NSCs) for cell replacement therapy in neurodegenerative disorders such as stroke. Stroke is
Background: Massive sequencing of genes from different environments has evolved metagenomics as central to enhancing the understanding of the wide diversity of micro-organisms and their roles in driving ecological processes. Reduced cost and high throughput sequencing has made large-scale projects achievable to a wider group of researchers, though complete metagenome sequencing is still a daunting
Background: Intimate partner violence (IPV) during pregnancy is a serious matter which threatens maternal and fetal health. The aim of this study was to develop a grounded theoretical model of women's experience of IPV during pregnancy and how they handle their situation. Method: Ten interviews with women who had experience of being exposed to IPV during pregnancy were analyzed using the grounded
Glutamic acid decarboxylase 65 (GAD65) and autoantibodies specific for GAD65 (GADA) are associated with autoimmune diseases including Stiff Person Syndrome (SPS) and Type 1 diabetes (T1D). GADA is recognized as a biomarker of value for clinical diagnosis and prognostication in these diseases. Nonetheless, it remains medically interesting to develop sensitive and specific assays to detect GAD65 pre
Proteus mirabilis bacilli play an important role in human urinary tract infections, bacteremia, and rheumatoid arthritis. The authors previously studied human complement C3 conversion by smooth-form P. mirabilis O10, O23, O30, and O43 lipopolysaccharides (LPSs) and showed that smooth Proteus LPSs fragmented C3 in a dose- and time-dependent manner. In the present study, one smooth P. mirabilis S195
Background: Swirl sign has previously been described in epidural hematomas as areas of low attenuation, radiolucency or irregular density. The aims of this study were to describe swirl sign in ICH, study its prevalence, study the reliability of the subjective evaluation on computed tomography (CT), and to explore its prognostic value. Methods: CTs of 203 patients with ICH were retrospectively eval
In this book several authors from the Nordic countries discuss the concept of identity as used within archaeology. Identity is as well part of the cultural heritage as an active component in today's political discussion. Ranging from present uses of identity today to the use of identity in the past, the 17 articles in the book show how identity works within archaeology.
It was predicted by Wigner in 1934 that an electron gas will undergo a transition to a crystallized state when its density is very low. Whereas significant progress has been made toward the detection of electronic Wigner states, their clear and direct experimental verification still remains a challenge. Here we address signatures of Wigner molecule formation in the transport properties of InSb nan
