It has been long known that hyperglycaemia-induced β-cell dysfunction precipitates type 2 diabetes (T2D) in insulin-resistant obesity, although the underlying mechanisms are still poorly defined. The few frequently used antidiabetic drugs on the market have still not satisfactorily demonstrated any long-lasting improvements of β-cell function and prevention of the disease. Islets synthesise and se

Lung cancer is a common cancer type associated with poor prognosis. Even in the group of patients with earlystage tumors, for which curative treatment is possible, lung cancer recurrence is frequent. The aim of this thesis was to investigate the potential prognostic role of mutations in tumor specimens, blood-based proteins and circulating tumor DNA.In study I, we performed EGFR mutation detection

På senare år har flera studier visat på att järnhalten ökar i sjöar och vattendrag i norra Europa. Järn spelar en nyckelroll i akvatiska miljöer genom att påverka tillgängligheten av andra näringsämnen i vattnet så som kväve och fosfor, vilket kan reglera tillväxten av växtplankton. Dessutom färgar järn tillsammans med organiskt material vatten brunt. När vattnet blir brunare försämras ljusklimate

Today, the innovation arena is open to a wider range of participants than previously acknowledged. One specifically neglected group of innovators in traditional innovation studies is non-R&D and non-managerial employees, also referred to as ‘ordinary’ employees by the existing body of literature on employee-driven innovation (EDI). These employees have no formal innovation function, meaning th

Incretin-based therapy is associated with low risk of hypoglycemia in type 2 diabetes mellitus (T2DM) possibly due to its glucose-dependency in stimulating insulin secretion and a sustained glucagon response during hypoglycemia. This is of special relevance when it is combined with insulin or given to elderly patients since both insulin therapy and high age are associated with impaired glucagon co

AbstractBackground: Atrial fibrillation (AF) is a major risk factor for ischemic stroke and the most common cause of cardioembolic stroke. Early detection of AF and AF subjects at high risk for stroke is therefore important. Beyond traditional strong risk factors, such as high age and hypertension, the improvement of risk prediction with existing risk scores, is modest for most other risk markers.

IMPORTANCE The positron emission tomography (PET) tracer [18F]flortaucipir allows in vivo quantification of paired helical filament tau, a core neuropathological feature of Alzheimer disease (AD), but its diagnostic utility is unclear. OBJECTIVE To examine the discriminative accuracy of [18F]flortaucipir for AD vs non-AD neurodegenerative disorders. DESIGN, SETTING, AND PARTICIPANTS In this cross-

Artificial outdoor lighting for pedestrians should provide for a safe and secure outdoor environment after dark. Pedestrian lighting thereby has implications for active transportation and sustainable mobility. Installations of new energy efficient lighting applications should be evaluated in terms of pedestrian’s perception, evaluation and behaviour in the lit environment. Today there is a lack of

Background: Unhealthy diets, the rise of non-communicable diseases, and the declining health of the planet are highly intertwined, where food production and consumption are major drivers of increases in greenhouse gas emissions, substantial land use, and adverse health such as cancer and mortality. To assess the potential co-benefits from shifting to more sustainable diets, we aimed to investigate

Aims/hypothesis: Galectin-1 modulates inflammation and angiogenesis, and cross-sectional studies indicate that galectin-1 may be a uniting factor between obesity, type 2 diabetes and kidney function. We examined whether circulating galectin-1 can predict incidence of chronic kidney disease (CKD) and type 2 diabetes in a middle-aged population, and if Mendelian randomisation (MR) can provide eviden

BACKGROUND: Food biodiversity, encompassing the variety of plants, animals, and other organisms consumed as food and drink, has intrinsic potential to underpin diverse, nutritious diets and improve Earth system resilience. Dietary species richness (DSR), which is recommended as a crosscutting measure of food biodiversity, has been positively associated with the micronutrient adequacy of diets in w

Importance: Preterm delivery has been associated with future cardiometabolic disorders in women. However, the long-term risks of chronic hypertension associated with preterm delivery and whether such risks are attributable to familial confounding are unclear. Such knowledge is needed to improve long-term risk assessment, clinical monitoring, and cardiovascular prevention strategies in women. Objec

Graves’ disease (GD) is an autoimmune disease characterized by hyperthyroidism and is caused by an interplayof genetic and environmental factors. One-third of patients with GD develop Graves’ ophthalmopathy (GO). Keyprocesses in the pathogenesis of GO are inflammation and adipogenesis in orbital tissue. Strong risk factorsassociated with the development of GO are smoking and radioiodine treatment

Importance: Trastuzumab emtansine (T-DM1) is presently approved for treatment of advanced breast cancer and after incomplete response to neoadjuvant therapy, but the potential of T-DM1 as monotherapy is so far unknown. Objective: To assess pathologic complete response (pCR) to standard neoadjuvant therapy of combination docetaxel, trastuzumab, and pertuzumab (DTP) vs T-DM1 monotherapy in patients

Aims/hypothesis: Five clusters based on clinical characteristics have been suggested as diabetes subtypes: one autoimmune and four subtypes of type 2 diabetes. In the current study we replicate and cross-validate these type 2 diabetes clusters in three large cohorts using variables readily measured in the clinic. Methods: In three independent cohorts, in total 15,940 individuals were clustered bas

Background: Near-infrared spectroscopy (NIRS) and intravascular ultrasound are promising imaging modalities to identify non-obstructive plaques likely to cause coronary-related events. We aimed to assess whether combined NIRS and intravascular ultrasound can identify high-risk plaques and patients that are at risk for future major adverse cardiac events (MACEs). Methods: PROSPECT II is an investig

The development of tau-PET allows paired helical filament tau pathology to be visualized in vivo. Increased knowledge about conditions affecting the rate of tau accumulation could guide the development of therapies halting the progression of Alzheimer's disease. However, the factors modifying the rate of tau accumulation over time in Alzheimer's disease are still largely unknown. Large-scale longi

Boreal forests and peatlands are globally significant carbon stores but they are threatened by rising air temperatures and changes in precipitation regimes and the frequency of natural disturbances. Predicting how the boreal biome will respond to climate change depends on being able to accurately model and upscale the greenhouse gas fluxes between these ecosystems and the atmosphere. This thesis f

For several decades, a whole range of critical approaches emphasizing networks, flows and mobility have gained ground in social theory and slowly made its way into governmental practice. In few fields of study has the epistemological shift been as marked in both theory and practice as urban studies in general, and those interested in public space in particular.
