Background: Ghrelin derives from endocrine cells (A-like cells) in the stomach (mainly the oxyntic mucosa). Its concentration in the circulation increases during fasting and decreases upon re-feeding. This has fostered the notion that the absence of food in the upper gastrointestinal (GI) tract stimulates the secretion of ghrelin. The purpose of the present study was to determine the concentration

BACKGROUND CONTEXT: Several studies report a favorable short-term outcome after nonoperatively treated two-column thoracic or lumbar burst fractures in patients without neurological deficits. Few reports have described the long-term clinical and radiological outcome after these fractures, and none have, to our knowledge, specifically evaluated the long-term outcome of the discs adjacent to the fra

Popular Abstract in Swedish Bakgrund Denna studie är en undersökning av barns musikskapande med synthesizer och dator. I studien deltog nio barn i åttaårsåldern. Musik utgör en viktig del i barns och ungdomars vardag och den stora exponering för musik som sker i vårt samhälle innebär att ingen är någon musikalisk nybörjare. Det är väl känt att barn kan skapa musik på egen hand, mest är det dock bToday’s children live in a world where music in all its different forms has become a significant factor in their everyday life. From earlier research we know that young children are able to create music by singing and using musical instruments. The present study was undertaken with eight-year-old children in school year 2 in order to investigate the children’s composing and composition processes u

BACKGROUND: Phosphoglucose isomerase (PGI, EC 5.3.1.9) is an essential metabolic enzyme in all eukaryotes. An earlier study of the PgiC1 gene, which encodes cytosolic PGI in the grass Festuca ovina L., revealed a marked difference in the levels of nucleotide polymorphism between the 5' and 3' portions of the gene.METHODS: In the present study, we characterized the sequence polymorphism in F. ovina

Background: The prognosis of Alzheimer’s disease (AD) might be influenced by many sociodemographic and clinical factors. Previous studies have investigated the main effects of critical predictors but few have analyzed potential interactions. We have studied the long-term cognitive outcome, nursing home placement (NHP) and mortality by interactions between factors in cholinesterase inhibitor (ChEI)

Malignant melanoma is a heterogeneous, malignant neoplastic disease, most often originating in the skin. Melanoma is characterized by a high mutational load and has a vastly variable prognosis, depending on disease stage. Genetic aberrations in the mitogen-activating protein kinase (MAPK) pathway are important in melanoma, of which mutations in BRAF and NRAS are the most common. Additionally, recu

Deoxygenation affects many continental shelf seas across the world today and results in increasing areas of hypoxia (dissolved oxygen concentration ([O2]) <1.4 ml/L). The Baltic Sea is increasingly affected by deoxygenation. Deoxygenation correlates with other environmental variables such as changing water temperature and salinity and is directly linked to ongoing global climate change. To place t

Aims/hypothesis: The risk of complications and medical consequences of type 2 diabetes are well known. Hospital costs have been identified as a key driver of total costs in studies of the economic burden of type 2 diabetes. Less evidence has been generated on the impact of individual diabetic complications on the overall societal burden. The objective of this study was to analyse costs of hospital

Bygg- och fastighetssektorn står för stora utsläpp av växthusgaser från byggnadsmaterial- och energianvändning. Byggbranschen står idag för ca en femtedel av Sveriges totala koldioxidutsläpp. Ett område med stor potential är byggnadsmaterial där IsoTimber är ett av företagen som driver utvecklingen framåt. IsoTimber är en relativt ny aktör inom byggsektorn som tillverkar prefabricerade väggar i trThe construction and real estate sector accounts for a large part of the emission of greenhouse gases from the usage of building material and energy. The construction industry today accounts for about one-fifth of Sweden’s total carbon dioxide emissions. One area with great potential is building materials where IsoTimber is one of the companies that drive the development forward. IsoTimber is a re

Kosovo, världens 193:e land, blir den sjätte staten som bildats från den serbdominerade jugoslaviska federationen sedan 1991, efter Slovenien, Makedonien, Bosnien och Montenegro som blev världens nyaste stat 2006. Kosovos status som självständig stat är dock fortfarande omstridd. Frågan om Kosovo är ett internationellt subjekt som har en rätt till externt självbestämmande och därmed är ett subjektKosovo, the world’s 193rd country, will be the sixth state carved from the former Serbian-dominated Yugoslav federation since 1991, after Slovenia, Croatia, Macedonia, Bosnia and Montenegro, which became the world’s newest state in 2006. Kosovo’s statehood is, however, still disputed. The question if Kosovo is a subject that has a right to external self-determination and therby hold international

As we age and need help with the chores that we used to perform on our own, there are two ways that we can get help in the current situation. The first is that you can get home care, which means that health care providers will come to the residents home and give him or her the care and help needed. The other option is to move into an assisted living form where there are health professionals on sit

With an increasingly population and urbanization, the solid waste management have become a major challenge for local authorities in developing countries all over the world. The local authorities must improve their waste management in order to minimize the negative effects of solid waste and to avoid future land use conflicts. At the same time the economical resources are limited and solid waste ma

Dealing with water diffuse pollution is a major problem for watershed managers. This problem raises many complicated questions, which are important to answer in order to reach water environment protection goals. This study suggested some possible answers for the country of Lithuania. Among them were the identification of critical source areas, the identification of sensitive areas and the applicat

Varje år diagnostiseras i Sverige ungefär 1100 personer med cancer i huvudhalsregionen. Typiska diagnoser är tungcancer, läppcancer och cancer i struphuvudet. I och runt om munhålan finns det stora skillnader i densitet mellan till exempel vävnad och tänder och vävnad och tandlagningar. I detta arbete så har effekterna av ett antal olika tandlagningsmaterial på dosberäkningarna undersökts. För a"Introduction: Around 1.000 people are diagnosed with head and neck cancer in Sweden every year. Radiotherapy is often used to treat these tumors. When irradiating patients in the head and neck area there are some problems. One of these problems is the large difference in density between the oral tissue and dental materials. Another problem is the image artifacts due to high-density materials

Monte Carlo-simuleringar har fått en ökad betydelse som forskningsverktyg inom nuklearmedicinsk bildgivning eftersom man på ett mycket kontrollerat sätt kan studera nästan vad man vill. I denna studie har datorsimuleringar av ett PET-system gjorts med ett program som heter GATE. PET (Positron Emission Tomography) är en nuklearmedicinsk bildgivningsteknik som används mer och mer inom sjukvården sIntroduction: Monte Carlo simulation is a powerful tool in research in the field of nuclear medicine imaging and there is a wide area of applications.

Possible alternative fuels are identified as compressed hydrogen, batteries, liquid hydrogen, ammonia, methanol, and biofuels, out of which

Bygg- och fastighetssektorn stod år 2020 för 21% av Sveriges totala utsläpp av växthusgaser (Boverket, 2023a). För att synliggöra och därigenom minska klimatpåverkan vid uppförandet av nya byggnader blev det den 1 januari 2022 obligatoriskt att genomföra klimatdeklaration av nya byggnader som kräver bygglov, med vissa undantag (Boverket, 2021a). Klimatdeklarationen ska redovisa klimatpåverkan frånThe construction and real estate sector accounted for 21 % of Sweden’s total green-house gas emissions in 2020. To mitigate the impact of new buildings, the Swedish government introduced a new law on climate declaration for new buildings called “lag om klimatdeklaration”. The law requires most new buildings, which already re-quired building permits, to perform a climate declaration. The climate de

Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations. These problems are mostly due to incompleteness in

Objective: To facilitate a greater likelihood of favorable response to new disease-modifying therapies, recruitment of patients at an earlier stage of their disease into clinical trials may be an attractive strategy. Hence, there is a need to develop widely accepted classification criteria for early-stage knee osteoarthritis (OA). We have proposed a set of classification criteria for early-stage k

Different migratory species have evolved distinct migratory characteristics that improve fitness in their particular ecological niches. However, when such species hybridize, migratory traits from parental species can combine maladaptively and cause hybrids to fall between parental fitness peaks, with potential consequences for hybrid viability and species integrity. Here, we take advantage of a na
