Protein aggregation is a key process in the development of many neurodegenerative disorders, including dementias such as Alzheimer's disease. Significant progress has been made in understanding the molecular mechanisms of aggregate formation in pure buffer systems, much of which was enabled by the development of integrated rate laws that allowed for mechanistic analysis of aggregation kinetics. Ho
Background: Management of young febrile infants is challenging. Therefore, several guidelines have been developed over the last decades. However, knowledge regarding the impact of introducing guidelines for febrile infants is limited. We assessed the impact of and adherence to a novel guideline for managing febrile infants aged ≤59 days. Methods: This retrospective cross-sectional study was conduc
Background and purpose — Reduced range of motion (ROM) and spasticity are common secondary findings in cerebral palsy (CP) affecting gait, positioning, and everyday functioning. These impairments can change over time and lead to various needs for intervention. The aim of this study was to analyze the development path of the changes in hamstring length, knee extension, ankle dorsiflexion, and spast
PURPOSE: To compare agreement of corneal epithelium thickness (ET) between AS-OCT system (RTVue, Optovue) and AS-OCT/Placido topographer (MS-39, CSO) in eyes with different stages of keratoconus (KC), and to assess the repeatability of RTVue AS-OCT. DESIGN: Prospective reliability analysis. METHODS: KC eyes were classified into forme fruste KC (FFKC), mild, moderate, and severe KC. Agreement was e
A hydraulic force aids diastolic filling of the left ventricle (LV) and is proportional to the difference in short-axis area between the left ventricle and atrium; the atrioventricular area difference (AVAD). Patients with repaired Tetralogy of Fallot (rToF) and pulmonary regurgitation (PR) have reduced LV filling which could lead to a negative AVAD and a hydraulic force impeding diastolic filling
A small, nucleotide-binding domain, the ATP-cone, is found at the N-terminus of most ribonucleotide reductase (RNR) catalytic subunits. By binding adenosine triphosphate (ATP) or deoxyadenosine triphosphate (dATP) it regulates the enzyme activity of all classes of RNR. Functional and structural work on aerobic RNRs has revealed a plethora of ways in which dATP inhibits activity by inducing oligome
Denna avhandling är en kvalitativ, livshistorisk och narrativ studie som undersöker hur 19 vuxna transmaskulina personer i Johannesburg och Kapstaden, Sydafrika, navigerar och förhandlar fram hållbara liv i de miljöerna de lever och rör sig i. Studiens teoretiska ramverk bygger på teoretiska inslag från feministisk geografi, queerfenomenologi, svart transfeminism och analyser av rasifierad kapitalThis dissertation is a qualitative, life history/narrative study that explores how 19 adult trans masculine people living in different urban areas around Johannesburg and Cape Town, South Africa, navigate and negotiate liveable lives in the spaces and places they live and move in. This study draws from the theoretical and analytical traditions of feminist geographies, queer phenomenology, black tr
Changes in the net carbon sink of boreal forests constitute a major source of uncertainty in the future global carbon budget and, hence, climate change projections. The annual net ecosystem exchange of carbon dioxide (CO2) controlling the terrestrial carbon stock results from the small difference between respiratory CO2 release and the photosynthetic CO2 uptake by vegetation. The boreal forest, an
The ring-like peripheral light-harvesting complex 2 (LH2) expressed by many phototrophic purple bacteria is a popular model system in biological light-harvesting research due to its robustness, small size, and known crystal structure. Furthermore, the availability of structural variants with distinct electronic structures and optical properties has made this group of light harvesters an attractive
Background: It has been suggested that carbidopa at high blood concentrations may counter the therapeutic effect of levodopa in Parkinson's disease by entering the brain and blocking central levodopa conversion to dopamine. We previously demonstrated equivalent plasma levodopa concentration in patients with Parkinson's disease during 16 h of (1) intravenous carbidopa/levodopa (DIZ101) infusion, (2
There are seventeen million people in the world who are stateless, not considered as citizens by any state. They suffer due to the current function of citizenship in the nation-state system, occupying a legal space outside of the system, yet, their lives are very much blighted by the system itself. This research examines the possibility that global citizenship could be a means to address stateless
Context. The light element (anti-)correlations shown by globular clusters (GCs) are the main spectroscopic signature of multiple stellar populations. These internal abundance variations provide us with fundamental constraints on the formation mechanism of stellar clusters. Aims. Using Gaia-ESO, the largest and most homogeneous survey of open clusters (OCs), we intend to check whether these stellar
Respiratory symptoms are ubiquitous and impair health-related quality of life in people with respiratory disease. This European Respiratory Society (ERS) task force aimed to provide recommendations for symptomatic treatment in people with serious respiratory illness. The ERS task force comprised 16 members, including representatives of people with serious respiratory illness and informal caregiver
In-situ remediation through the injection of bioremediation fluids is becoming increasingly common for treating contaminated sites. Contaminants are targeted for treatment either directly at the source zone or through injections that form a permeable reactive barrier to prevent further transport of the contaminants. Commonly, multiple injections are performed in a grid covering an area of strategi
Background: Reliable and valid assessment of paranoia is important in forensic psychiatry for providing adequate care. VR technology may add to current assessment procedures, as it enables observation within realistic (social) situations resembling the complexity of everyday life. VR constitutes a promising tool within forensics, due to the restricted nature of forensic psychiatric hospitals and e
Rationale: A care bundle approach to the management of spontaneous intracerebral hemorrhage (ICH) has been shown to benefit patients in low- and middle-income countries (LMIC), but uncertainty persists over the specific components and its applicability in high-income countries (HICs). Aims: An international collaborative initiative aimed at determining whether implementation of a care bundle impro
With the rapid development of blood biomarkers (BBMs) related to amyloid-β (Aβ) pathology in Alzheimer's disease (AD), the question arises whether these can replace the accepted reference standard, positron emission tomography (PET), for assessing Aβ burden. BBMs can differentiate Aβ status reliably in cognitively impaired patients, but two-threshold strategies to further improve their performance
This study investigates how rescue service response times and staffing solutions relate to both citizen satisfaction with rescue services and the adoption of individual fire safety measures in Sweden. Data were drawn from Statistics Sweden's satisfaction index, rescue service response times from KOLADA, and survey data from the Swedish Civil Contingencies Agency on ownership of functional smoke de
In this chapter, I describe how technological progress triggers and shapes structural change within the economy and society, which in turn—if the resulting changes are significant enough—may shift the scope and outcome of established legislation and regulatory frameworks. The argument presented focuses on the ongoing digitalization, using its common technological characteristics to identify and de
En av de vanligaste frågorna som brukar ställas till astronomer är om det finns liv någon annanstans i universum. Vi har ännu inget enkelt svar. Framsteg mot ett svar på denna fråga görs lite i taget. Den här avhandlingen är ett av dessa steg.Min forskning är inriktad på atmosfärerna hos så kallade "ultra-hot Jupiters": planeter i Jupiters storlek som kretsar så nära sina stjärnor att de hettas upOne of the biggest questions people ask astronomers is whether life exists elsewhere in the universe. Unfortunately, we don’t yet have an answer. Instead, progress towards an answer comes in small, careful steps. This thesis is one of those steps.My research has focused on the atmospheres of "ultra-hot Jupiters": planets the size of Jupiter that orbit so close to their stars they are heated to tho
