Polyvinyl chloride (PVC) is a common thermoplastic whichfinds widespread applications in the construction industry for usage inceiling linings, flooring materials, electrical cables and roofing materials. Several fire requirements are put on these types of applications. For fire safety engineering and product development, thermo-chemical decomposition modeling of PVC isrequired. The FIRETOOLS proj
Background--Atherosclerosis is an inflammatory lipid disorder and the main underlying pathology of acute ischemic events. Despite a vast amount of data from murine atherosclerosis models, evidence of B-cell involvement in human atherosclerotic disease is limited. We therefore investigated the association of circulating B-cell subtypes with the occurrence of secondary cardiovascular events in advan
Dysregulation of gene expression in islets from type 2 diabetic patients might be causally involved in the development of hyperglycemia or it could develop as a consequence of hyperglycemia, i.e. glucotoxicity. To separate the genes potentially causally involved in pathogenesis from those likely to be secondary to the hyperglycemia we exposed islets from human donors to normal or high glucose conc
Gestational diabetes mellitus(GDM) defines an unhealthy state of hyperglycaemia that develops in response to an otherwise normal physiological adaptive insulin resistance state during pregnancy. However, the exact plasma glucose levels differentiating the unhealthy GDM state from a normal pregnancy is unknown, and relies upon arbitrary cut off criteria based on associations with adverse health out
BACKGROUND AND PURPOSE: There are, to date, no MR imaging diagnostic markers for Lewy body dementia. Nigrosome 1, containing dopaminergic cells, in the substantia nigra pars compacta is hyperintense on SWI and has been called the swallow tail sign, disappearing with Parkinson disease. We aimed to study the swallow tail sign and its clinical applicability in Lewy body dementia and hypothesized that
Diffusion tensor imaging (DTI) has been used to study microstructural white matter alterations in a variety of conditions including normal aging and Alzheimer’s disease (AD). White matter hyperintensities (WMH) are common in cognitively healthy elderly as well as in AD and exhibit elevated mean diffusivity (MD) and reduced fractional anisotropy (FA). However, the effect of WMH on statistical analy

Background: Glioblastoma is the most common and aggressive type of primary brain tumor in adults. A key problem is the capacity of glioma cells to inactivate the body’s immune response. The complement system acts as a functional bridge between the innate and adaptive immune response. Still, the role of the complement system has almost been forgotten in glioma research. In our present study, we hyp
Hypertension is a hemodynamic disorder and one of the most important and well-established risk factors for vascular diseases such as stroke. Blood vessels exposed to chronic shear stress develop structural changes and remodeling of the vascular wall through many complex mechanisms. However, the molecular mechanisms involved are not fully understood. Hypertension-susceptible genes may provide a nov
I början av 1930-talet var nära 200 000 kvinnor anställda som hembiträden i svenska hushåll, men många var missnöjda med sin arbetssituation. Under hotet om deras flykt från yrket aktualiserades genom en motion i Sveriges riksdag 1931 den så kallade hembiträdesfrågan, som skulle bli ett hett debattämne in i nästa decennium. Året därpå fick den svenska ljudfilmen sin första stora braksuccé: Vi som
The patient is the centre of a web of relationships, and the impact of his/her disease on family members and caregivers must be taken into account. The aim of this study was to identify the specific instruments that measure the impact of a dermatological disease on the quality of life (QoL) of family members, by performing a systematic search of the literature. Fifteen papers were identified, desc
Biological nitrogen removal in a one sludge system based on alternating operation is described. Results from a half year of operation in a plant designed for a population of 33,000 people are presented showing 90% removal of total-nitrogen, 98% removal of BOD and 74% removal of total-phosphorus (without addition of chemicals). An experiment showing the parameter variation in the plant over 24 hour
An investigation with respect to inhibition of nitrification of wastewater from 109 Swedish municipal wastewater treatment plants was performed. Flow proportional, 24-hour composite samples were collected during one week, and then analysed using the screening method. Inhibition of nitrification above 10% was found at only 20 plants. In general, the load of inhibiting substances is limited in Swedi
Concentration dependent solvation of RbBr in freestanding sub-2 nm water clusters was studied using core level photoelectron spectroscopy with synchrotron radiation. Spectral features recorded from dilute to saturated clusters indicate that either solvent shared or contact ion pairs are present in increasing amount when the concentration exceeds 2 mol kg-1. For comparison, spectra from anhydrous R
Aims: Exaggerated hepatic glucose production is one of the hallmarks of type 2 diabetes. Sulforaphane (SFN) has been suggested as a new potential anti-diabetic compound. However, the effects of SFN in hepatocytes are yet unclear. Accumulating evidence points to the close structural contacts between the ER and mitochondria, known as mitochondria-associated ER membranes (MAMs), as important hubs for
The methyl xanthate ester is presented as a versatile protective group for alcohols. Hydroxyl groups can easily be transformed into methyl xanthate esters by several methods and are commonly used as an auxiliary in the Barton-McCombie reaction. We show that these methyl xanthate esters can readily and chemoselectively be cleaved under mild conditions by the action of diethylenetriamine using micro
Conventional industrial robots are heavily dependent on hard automation that requires pre-specified fixtures and time-consuming (re)programming performed by experienced operators. In this work, teaching by human-only demonstration is used for reducing required time and expertise to setup a robotized assembly station. This is achieved by the proposed framework enhancing the robotic system with adva
