Knowledge concerning the normal aging of cerebral white matter will improve our understanding of abnormal changes in neurodegenerative diseases. The microstructural basis of white matter maturation and aging can be investigated using diffusion tensor imaging (DTI). Generally, diffusion anisotropy increases during childhood and adolescence followed by a decline in middle age. However, this process
BACKGROUND: The orexins (hypocretins) are recently discovered hypothalamic peptides that are involved in the regulation of sleep, appetite and state of arousal. In the present study, we investigated the relationship between cerebrospinal fluid (CSF) orexin and specific psychiatric symptoms in suicidal patients. METHODS: A total of 101 patients were enrolled in the study shortly after a suicide att
A novel approach to the visualisation of soot is presented. It relies on a combination of laser-induced soot vapourisation and consecutive polarisation spectroscopy. Upon soot vapourisation, molecular fragments (for example, C-2) emerge, and may serve as effective tracers for soot. In this study we demonstrate that saturated polarisation spectroscopy on photoinduced C-2 can be exploited for soot d
A subset of populations of the European taxa of Carex sect. Digitatae, including Carex digitata, C. pallens, C. ornithopoda, C. pediformis ssp. rhizodes and C. humilis have been investigated for allozyme variation. The (presumably) distantly related C. pendula was used a's a reference taxon. Carex digitata, C. pallens and C. ornithopoda on the one hand, and C. humilis and C. pediformis on the othe
Conceptually, this paper is about make-believe states and how such state is a socially constructed space, imagined and performed by those who perceive themselves as belonging to that state. It asks through what imaginaries and performative practices does a state come into being? Make-believe is here employed as an analytical category to refer both to the work of the imagination and to the material
Are capitalists more likely than others to justify ‘immoral’ acts such as bribery ortax evasion? This chapter investigates the conditions under which this is the case.While qualitative studies continue to document the nuances, mechanisms, andpractices of cheating and fraud among capitalists, quantitative work that tests the presence of fraud in modern economic life across a wide range of societies
Recent advances in proteomic technologies have made high throughput profiling of low abundance proteins in large epidemiological cohorts increasingly feasible. We investigated whether aptamer-based proteomic profiling could identify biomarkers associated with future development of type 2 diabetes (T2DM) beyond known risk factors. We identified dozens of markers with highly significant associations
Background: Caldicellulosiruptor kronotskyensis has gained interest for its ability to grow on various lignocellulosic biomass. The aim of this study was to investigate the growth profles of C. kronotskyensis in the presence of mixtures of glucose–xylose. Recently, we characterized a diauxic-like pattern for C. saccharolyticus on lignocellulosic sugar mixtures. In this study, we aimed to investiga
The Kattegat has, since the 1980s, been subject to extensive investigations focusing on various aspects of the marine environment. The most important reasons for this concentration of work are marine eutrophication, periodically occurring oxygen deficiency in the bottom-water and subsequent benthic mortality. In this study a previously not discussed sill area separating two deep areas in the Katte
Popular Abstract in Swedish Fjärrvärme är en väletablerad teknik som främst används för uppvärmning av byggnader och varmvatten. I Sverige värms över 80% av flerbostadshusen med fjärrvärme, vilket innebär att de flesta svenskar faktiskt bor i ett fjärrvärmeuppvärmt hus. Fjärrvärme är inte enbart en svensk teknik, utan används över hela värden där behov av uppvärmning finns. Länderna i Norden och ÖThe objective of this thesis is to contribute to improved performance of district heating systems by focusing on three items. Item 1: Study of three methods for improving the performance of sub-systems within buildings connected to the distribution network. The methods can be considered as more or less innovative. Results from two of these measures are quantified in terms of so-called Primary Ener
Objective: EEG is commonly used to predict prognosis in post anoxic coma. We investigated if stimulus-induced rhythmic, periodic or ictal discharges (SIRPIDs) add prognostic information after cardiac arrest. Methods: In the multicenter Targeted Temperature Management trial, routine-EEGs were prospectively recorded after rewarming (≥36 h). Presence and subtype of SIRPIDs and main EEG-pattern (benig
Many children in primary school listen and learn through their second language, often under noisy listening conditions. This thesis is based on assessments of 7 to 9-year-old primary school children (N=98) attending Swedish schools in areas of low socio-economic status where most students had immigration background. The overall aim of this thesis was to increase knowledge on how multitalker babble
Cooperation and joint actions are often investigated in terms of how individuals explicitly coordinate their plans and intentions to achieve a shared goal. However, goals may also be achieved without prior arrangements, when, for instance, an individual takes part in someone else’s action without an explicit agreement, helping that action to be performed. Participating in social interaction may be
BACKGROUND: Thrombosis is one of the most important causes of morbidity in the medical field. Several independent in vitro studies have shown that the fibrinolytic process may be enhanced by ultrasound, but the effect of ultrasound on thrombus formation in vivo is unexplored. The present study was designed to investigate this matter. METHODS: In a blind randomized study, standardized arteriotomies
Brain-derived neurotrophic factor (BDNF) and other neurotrophins are believed to play an important role in affective disorders. In this study we investigated plasma-BDNF response during an incremental exercise test in 18 patients suffering from moderate major depressive disorder (MDD) and 18 controls. The patients were not treated with antidepressants or neuroleptics. Possible associations between
Photoredox catalysis is a rapidly expanding field, in which organic transformations are catalysed using light. The most commonly used photoredox catalysts (PCs) are transition metal complexes which absorb in the visible region of the electromagnetic spectrum. Traditionally, such PCs are based on scarce and expensive metals, such as ruthenium or iridium, in combination with polypyridyl ligands. Res
Popular Abstract in Swedish Den här avhandlingen handlar om hur moln påverkas av luftburna partiklar, så kallade aerosolpartiklar. Moln bildas i atmosfären när vatten övergår från gasfas till vätskefas, det vill säga när vattenånga kondenserar. För att molndroppar ska kunna bildas krävs dock aerosolpartiklar, som vattenångan kan kondensera på. Antalet partiklar i luften kan därigenom påverka hur mCloud droplets never form in the atmosphere without a seed in the form of an aerosol particle. Changes in number concentrations of aerosol particles in the atmosphere can therefore affect the number of droplets in a cloud. Higher concentrations of aerosol particles in the atmosphere lead to clouds with more droplets and if the amount of liquid water in the clouds stay the same, the droplets become
Differentiated thyroid cancer (DTC) has a good prognosis; however, patients often need lifelong follow up, and they face potential side effects. The aim of this study was to investigate health anxiety among DTC patients and its relationship to TSH suppression. In 2020, patients from a previous cohort who were from Stockholm completed the 14-item Short Health Anxiety Inventory (SHAI-14; 0–42; 18 be
