Background: Insulin is a therapeutic protein that is widely used for the treatment of diabetes. Its biological function was discovered more than 80 years ago and it has since then been characterized extensively. Crystallization of the insulin molecule has always been a key activity since the protein is often administered by subcutaneous injections of crystalline insulin formulations. Over the year

Pollination by bees is important for food production. Recent concerns about the declines of both domestic and wild bees, calls for measures to promote wild pollinator populations in farmland. However, to be able to efficiently promote and prioritize between measures that benefit pollinators, such as modified land use, agri-environment schemes, or specific conservation measures, it is important to

Quantifying the water exchange between a forest stand and the atmosphere is of major interest for the prediction of future growth conditions and the planning of silvicultural treatments. In the present study, we address (i) the uncertainties of sap flow estimations at the tree level and (ii) the performance of the simulation of stand transpiration. Terrestrial laser scan images (TLS) of a mature b

In recent years, low-cost flights to smaller cities in Central and Eastern Europe grew fast. This growth offered tourists new possibilities to explore new, lesser-known destinations at a low price. At the same time, urban tourism is a common strategy for urban regeneration and development in Central and Eastern Europe, and therefore, a significant factor of the economic restructuring of Post-Socia

Scientific summary: Ground settlement due to groundwater drainage during construction is important to be considered since ground settlement may cause severe building damages. The calculation of ground settlement contained several parameters with different magnitude of uncertainties. Thus a risk evaluation of ground settlement is necessary. The aim of this thesis was first to build a soil strata mo

Populärvetenskaplig sammanfattning: Naturbetesmarker är en av de miljöer som håller den hösta biologiska mångfalden i Sverige (Ingelög et al., 1993). Idag finns endast 10-12 % naturbetesmarker kvar (Jordbruksverket 2005a) av de 2 miljoner hektar som fanns i Sverige på mitten av 1800-talet (WWF, 2006). Naturbetesmarkerna innehar en speciell flora som är anpassad för kontinuerlig störning och näring

Materials that are stored or used in damp climates may be subject to mould growth. However, all materials are not equally susceptible to mould growth. For each specific material, there is a critical moisture level. If this is exceeded, there is a risk that mould fungi will develop on the material. In a building, different constructions are exposed to different climatic conditions. To minimise the

Biomarkers are used in molecular biology to predict characteristics of interest and are applied in agriculture to accelerate the breeding of target traits. Proteomics has emerged as a promising technology for improved markers by providing a closer view to the phenotype than conventional genome-based approaches. However, a major challenge for biomarker development is that the identified biological

Pollination is a key ecosystem service for global agriculture but evidence of pollinator population declines is growing. Reliable spatial modelling of pollinator abundance is essential if we are to identify areas at risk of pollination service deficit and effectively target resources to support pollinator populations. Many models exist which predict pollinator abundance but few have been calibrate

Osteoarthritis of the carpometacarpal joint at the base of the thumb (CMC1 OA) is common and causes difficulty in grasp, grip, and fine manipulation of the hand. Surgery is recommended after failure of non-operative treatment, andevidence from short and medium-term follow-up studies shows successful relief of pain and return of function. Previous investigations of epidemiology and risk factors wer

There is an extensive research that explores the reproduction of transnational communities and relations, with a particular focus on locality, identity and culture. However, the existing research emanates from the case studies of immigrant communities in Western-type democracies, while we know little about migrant transnationalism in non-Western migration regimes such as Russia, where migrant work

This work provides new insights into the presence of 239Pu, 240Pu, 241Pu, and 236U in the Southern Hemisphere through the study of peat bog cores from marshlands in Madagascar (19°S). 210Pb, 238Pu and 239+240Pu activities were characterized by alpha spectrometry in previous studies. Here, Pu from alpha-spectrometry discs corresponding to 10 peat-bog cores (85 samples) was reassessed for the aim of

PURPOSE: The prevalence of iron deficiency (ID) in Left Ventricular Assist Device (LVADs) recipients is not known nor has the association between ID and peak oxygen uptake (VO2) been reported. The aim of this study was to study to investigate the prevalence of ID in this population and the association between ID and VO2. METHODS: Data was included from LVAD recipients at Rigshospitalet, Denmark (D

Unstructured citizen-science data are increasingly used for analysing the abundance and distribution of species. Here we test the usefulness of such data to predict the seasonal distribution of migratory songbirds, and to analyse patterns of migratory connectivity. We used bird occurrence data from eBird, one of the largest global citizen science databases, to predict the year-round distribution o

Afhandlingens empiriske udgangspunkt er Bornholms vikingetidsskatte (ca. 850-ca. 1150), med særlig fokus på 34 udgravede lokaliteter, der i hidtil uset skala gør det muligt, at inddrage den arkæologiske kontekst i tolkningen af skattenes betydninger. I afhandlingen opstilles tre forskningsspørgsmål: 1) Afspejler skattene de mennesker, der akkumulerede, håndterede og deponerede dem, og er det mulig

1. Neuropeptide Y (NPY) and peptide YY (PYY) act at receptors referred to as Y1 and Y2, while the Y3 receptor is specific to NPY and does not recognize PYY. The effects of NPY, its related peptides and a series of newly constructed chimeric NPY-PYY peptides were examined on excitatory and inhibitory postsynaptic currents (e.p.s.cs and i.p.s.cs, respectively) in rat dorsomedial nucleus tractus soli

Att ha ångest är en del av att vara människa. Men när ångesten tar överhand kan det handla om ångestsyndrom, en psykiatrisk diagnos. Aldrig är det så jobbigt att vara människa som under tonårstiden. Många unga flickor och pojkar sover sämre, upplever mer stress och har det kämpigt psykiskt. Begreppet psykisk ohälsa är samtidigt svårt att förhålla sig till, eftersom det ofta överlappar vanliga livs

Previous studies in the rat have shown that a serotonergic depletion greatly potentiates the learning and memory impairments produced by pharmacological or lesion-induced cholinergic blockade in the forebrain. The impairment produced by combined serotonergic-cholinergic lesions is reminiscent of that seen in memory-impaired aged rats. In the present experiment, we investigated whether grafts of ch
