Abstract: Birds have evolved morphological, physiological and behavioural adaptations, encoded in their migratory programs, to enable successful migration. Sometimes, even closely related species, such as the Eurasian reed warbler and the sedge warbler, may adopt different migration strategies to reach their wintering grounds in sub-Saharan Africa. To study them in detail, we aimed to compare the

Background: We aimed to evaluate cumulative occurrence and impact of COVID-19 in patients with chronic respiratory failure (CRF) treated with long-term oxygen therapy (LTOT). Material and methods: Data were obtained from the SCIFI-PEARL study on the entire Swedish population and on patients with oxygen-dependent CRF and no COVID-19 diagnosis before start of LTOT. Analyses were performed for three

Wintering energy management in small passerines has focused on the adaptive regulation of the daily acquisition of energy reserves within a starvation-predation trade-off framework. However, the possibility that the energetic cost of living, i.e. basal metabolic rate (BMR), is being modulated as part of the management energy strategy has been largely neglected. Here, we addressed this possibility

The 2010 population and housing census in Ghana revealed that more than half of the Ghanaian population lived in urban centers. Critical to the phenomenon of urbanization is the question of how to sustainably feed the urban population especially the urban poor as rapid urbanization has the tendency to urbanize poverty. This has led to renewed policy debate about the implications of farming in citi

Autoimmune (type 1) diabetes mellitus is a chronic disease without a cure. It affects primarily young people but may be diagnosed at any age. Strong genetic susceptibility characterizes the most common form of autoimmune diabetes in children younger than 18 years of age. Autoimmune diabetes is generally assumed to be hereditary, although the majority of patients do not have a family history of aut

Background: The epidermal growth factor receptor (EGFR) is pivotal for growth of epithelial cells and is overexpressed in several epithelial cancers like head and neck squamous cell carcinoma (HNSCC). EGFR signalling is also involved in diverse innate immune functions in epithelia. We previously found a role for EGFR in modulating the complement system in skin, this prompted an investigation into

Antibody microarray is a novel technology that will allow us to efficiently perform global proteome analysis. Performing rapid and multiplexed analysis on complex proteomes, such as human serum, targeting also low-abundant analytes will, however, place high demands upon the microarray design with respect to logistics, specificity and sensitivity. In this study, we have shown that non-purified affi

A combined sample preparation and sample presentation device, Integrated Selective Enrichment Target (ISET), consisting of an array with 96 perforated nanovials is described. Each perforated nanovial can be filled with soild-phase extraction media for purification and concentration of biomolecules prior to mass spectrometry. The ISET platform provides an efficient, economic and generic sample trea

Aims: This study investigates the risk of small for gestational age (SGA) in relation to country of origin of the mother. The role of psychosocial resources, socioeconomic and lifestyle factors was examined in different causal models. Methods: Among all pregnant nulliparous women in the city of Malmo¨ , Sweden, who gave birth in 1991 – 92, 872 (87.7%) women completed a questionnaire during their f

To survive on a global market, small and medium size enterprises (SMEs) require affordable and competitive industrial automation for high quality flexible manufacturing. This thesis contributes to the development of robot concepts that fit the needs of SMEs. A major part of the thesis deals with the modeling of the three degree-of-freedom (DOF) Gantry-Tau parallel kinematic robot, which has the po

Syftet med denna studie är att analysera hur personal inom socialtjänsten tolkar, definierar och upplever ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. Dessutom uppmärksammas hur den intervjuade och observerade personalen uppfattar och kategoriserar de inom projektet anställda samordnarna. De anställda inom socialtjänsten upplever att projektet kommit The aim of this study is to analyze how the Social Services personnel interpret, define and perceive, on the one hand, the project “Motverka Våld och Gäng” meaning “Counteract Violence and Gangs”, and on the other hand the role of the Coordinators employed in this project. Heads of units and Social Secretarys were interviewed, as well as observed and recorded at meetings. The personnel of the Soc

The sphere detector is near-optimal in bit error rates (BER) performance for MIMO detection, but it suffers from the lower detection throughput. In this paper, we propose an improvement to the sub-optimal MIMO detection. The proposed detector can achieve a much higher detection throughput than the sphere detector, with a comparable complexity and a small degradation in BER performance at high sign

Accelerated cell aging, indexed in peripheral leukocytes by telomere shortness and in peripheral blood mononuclear cells (PBMCs) by telomerase activity, has been reported in several studies of major depressive disorder (MDD). However, the relevance of these peripheral measures for brain indices that are presumably more directly related to MDD pathophysiology is unknown. In this study, we explored

The generation of human induced pluripotent stem cells (hiPSCs) represents an exciting advancement with promise for stem cell transplantation therapies as well as for neurological disease modeling. Based on the emerging roles for astrocytes in neurological disorders, we investigated whether hiPSC-derived astrocyte progenitors could be engrafted to the rodent spinal cord and how the characteristics
