Skogar täcker ca 31% av jordens landyta och lagrar stora mängder kol i biomassa och i marken. I klimatavtalet från Paris 2015 lyfts skogars roll som sänkor och reservoarer av kol fram och undertecknande länder uppmanas att implementera strategier för hållbart skogsbruk som ytterligare förstärker skogars roll som sänkor av växthusgaser. Ett aktivt skogsbruk påverkar klimat och miljö på många olika Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies. Managing forests for climate mitigation purposes is, however, complex since management

Inom nuklearmedicinen utnyttjas radioaktiva läkemedel och strålningen som sänds ut från dessa för att diagnosticera och behandla ett flertal olika sjukdomar. Det radioaktiva läkemedlet ges ofta till patienten som en intravenös injektion, och läkemedlets egenskaper i kombination med patientens fysiologi och eventuella sjukdom avgör hur läkemedlet sedan fördelas, omsätts och utsöndras från kroppen. Many nuclear medicine investigations rely on gamma-camera imaging to study and quantify the distribution of radiopharmaceuticals or radionuclides in the patient as a function of time. This is typically used for diagnostic studies of physiological functions or for calculation of absorbed doses following radionuclide therapy. In this work, computational patient models (phantoms) have been developed

Background and aims: TCF7L2 is both an activator and an inhibitor of transcription and the most highly associated type 2 diabetes gene known to date. It influences beta cell survival and function, i.e. incretin hormonal effects, insulin processing and secretion. However, its target genes in pancreatic islets are not fully described and the molecular mechanism whereby it propagates its effects on i

Background: The solute carrier family 30 member 8 gene (SLC30A8) encodes a zinc transporter in the pancreatic beta cells and the major C-allele of a missense variant (rs13266634; C/T; R325W) in SLC30A8 is associated with an increased risk of type 2 diabetes (T2D). We hypothesized that the association between zinc intake and T2D may be modified by the SLC30A8 genotype. Results: We carried out a pro

Background: Combinations of multiple fatty acids may influence cardiometabolic risk more than single fatty acids. The association of a combination of fatty acids with incident type 2 diabetes (T2D) has not been evaluated. Methods and findings: We measured plasma phospholipid fatty acids by gas chromatography in 27,296 adults, including 12,132 incident cases of T2D, over the follow-up period betwee

Aims/hypothesis: Sugar-sweetened beverages (SSBs) are a major dietary contributor to fructose intake. A molecular pathway involving the carbohydrate responsive element-binding protein (ChREBP) and the metabolic hormone fibroblast growth factor 21 (FGF21) may influence sugar metabolism and, thereby, contribute to fructose-induced metabolic disease. We hypothesise that common variants in 11 genes in

The prognostic importance of tumor-specific nuclear insulin receptor (InsR) expression in breast cancer is unclear, while membrane and cytoplasmic localization of InsR is better characterized. The insulin signaling network is influenced by obesity and may interact with the estrogen receptor a (ERα) signaling. The purpose was to investigate the interplay between nuclear InsR, ER, body mass index (B

Background: Accumulating evidence suggests that individual circulating saturated fatty acids (SFAs) are heterogeneous in their associations with cardio-metabolic diseases, but evidence about associations of SFAs with metabolic markers of different pathogenic pathways is limited. We aimed to examine the associations between plasma phospholipid SFAs and the metabolic markers of lipid, hepatic, glyca

Den första januari 2012 sänkte den då sittande alliansregeringen momssatsen för restaurang- och cateringtjänster från 25 % till 12 %. Det övergripande målet med den lägre momssatsen är att stimulera efterfrågan på okvalificerad arbetskraft genom att skapa förutsättningar för lägre priser och därmed ökad efterfrågan på restaurangföretagens tjänster.Under tiden efter genomförandet av den sänkta momsA significant part of the labour market debate is devoted to issues concerning problematic youth. Expressions like “the lost generation” is coined to address the very core of the matter. It captures the difficulties for low-skilled young people to gain a sustainable work life in an education-oriented society. A strategy to increase employment opportunities specifically suited for the latter group

PurposeIn early breast cancer (BC), five conventional biomarkers—estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor 2 (HER2), Ki67, and Nottingham histologic grade (NHG)—are used to determine prognosis and treatment. We aimed to develop classifiers for these biomarkers that were based on tumor mRNA sequencing (RNA-seq), compare classification performance, a

Avhandlingen Naturliga medborgare undersöker hur frilfutsliv och lägerverksamhet använts som metoder för medborgarfostran i scoutrörelsen och Unga Örnar under perioden 1925–1960. Frågorna som undersökts innefattar hur organisationerna artikulerade ideal om medborgarskap, hur barn och ungdomar skulle fostras till goda medborgare samt mer specifikt hur natur och friluftsliv skulle bidra till att för

Modern wind turbines are designed to withstand approximately for a lifetime of 20 years [1]. However, a very long design life of 100 years or more can be expected for high-quality concrete foundations. Thus there is a big difference in lifetime between wind turbines and foundations. There is a significant economic benefit of replacing the out-of-date wind turbine with a new turbine of better power

This thesis focuses on the adaptive strategies of daphnids that allows them to maintain stable populations while deal with UV radiation, highlighting the differences in the responses that populations with different evolutionary histories may have.Although exposition to lethal doses in nature is unlikely, sub-lethal UV-B radiation doses may have strong impacts on zooplankton. This work initiates wi

Background: Lead time (LT) is of key importance in early detection of cancer, but cannot be directly measured. We have previously provided LT estimates for prostate cancer (PCa) using archived blood samples from cohorts followed for many years without screening. Objective: To determine the association between LT and PCa grade at diagnosis to provide an insight into whether grade progresses or is s

BACKGROUND: Identification of risk factors for rapid joint destruction in early rheumatoid arthritis (RA) can be helpful for optimizing treatment, and improving our understanding of destructive arthritis and its mechanisms. The objective of this study was to investigate the relationship between early RA patient characteristics and subsequent rapid radiographic progression (RRP).METHODS: An incepti

Preclinical studies on the role of erythropoietin (EPO) in bone metabolism are contradictory. Regeneration models indicate an anabolic effect on bone healing, whereas models on physiologic bone remodeling indicate a catabolic effect on bone mass. No human studies on EPO and fracture risk are available. It is known that fibroblast growth factor 23 (FGF23) affects bone mineralization and that serum

Background: Chronic musculoskeletal pain is common in adolescents, and it has been shown that adolescents with pain may become young adults with pain. Pain often coincides with psychosomatic symptoms in adults, but little is known about longitudinal associations and predictors of pain in adolescents. The aim was to investigate chronic musculoskeletal pain and its associations with health status, s
