Blodtest – fönster till hjärnan vid Alzheimers sjukdom

Technical developments have paved the way for the development of ultrasensitive analytical methods that allow for precise quantification of brain-specific proteins in blood samples. Plasma levels of amyloid β, specifically the Aβ42/40 ratio, are reduced in Alzheimer's disease (AD) and show concordance with brain amyloidosis assessed by PET, but the overlap with normal elderly may be too large for

Room-temperature serial synchrotron crystallography structure of Spinacia oleracea RuBisCO

Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is the enzyme responsible for the first step of carbon dioxide (CO2) fixation in plants, which proceeds via the carboxylation of ribulose 1,5-biphosphate. Because of the enormous importance of this reaction in agriculture and the environment, there is considerable interest in the mechanism of fixation of CO2 by RuBisCO. Here, a serial synch

Muscle preservation in proximal nerve injuries : a current update

Optimal recovery of muscle function after proximal nerve injuries remains a complex and challenging problem. After a nerve injury, alterations in the affected muscles lead to atrophy, and later degeneration and replacement by fat-fibrous tissues. At present, several different strategies for the preservation of skeletal muscle have been reported, including various sets of physical exercises, muscle

History of TRP channels and lower urinary tract function and dysfunction

The history of TRP channels and bladder started in the 1980-ies with the studies of Maggi and collaborators, who created the basis for using capsaicin and other vanilloids in LUT disorders. This narrative review gives a brief history of bladder TRP channels, from their discovery, distribution, and function in the bladder to the rationale for and current status of the use of agents acting on them i

Reweighting Monte Carlo predictions and automated fragmentation variations in Pythia 8

This work reports on a method for uncertainty estimation in simulated collider-event predictions. The method is based on a Monte Carlo-veto algorithm, and extends previous work on uncertainty estimates in parton showers by including uncertainty estimates for the Lund string-fragmentation model. This method is advantageous from the perspective of simulation costs: a single ensemble of generated eve

Distribution of benefits and adverse effects and their role in industrial symbiosis decision-making – A Swedish case study

Industrial symbiosis (IS) has been recognized as an important approach to succeed in the transition towards increased circularity in industry and society. IS involves collaboration between different actors sharing resources, aiming to minimize waste, improve resource and/or energy efficiency, resulting in reduced emissions and environmental impact. This study conducts an embedded single case study

Developmental noise and phenotypic plasticity are correlated in Drosophila simulans

Non-genetic variation is the phenotypic variation induced by the differential expression of a genotype in response to varying environmental cues and is broadly categorized into two types: phenotypic plasticity and developmental noise. These aspects of variation have been suggested to play an important role in adaptive evolution. However, the mechanisms by which these two types of non-genetic varia

Aid Fragmentation and Aid Effectiveness in Sub-Saharan Africa

This paper examines the effect of aid fragmentation on the aid-growth nexus in Sub-Saharan Africa from 1990-2017. Aid fragmentation is measured by both the concentration index (Herfindahl index and ratio of contribution by largest three donors) and donor counts (total number of donors and number of small donors). We find a significant negative effect of aid fragmentation on the effectiveness of ai

Health-related quality of life by type of breast surgery in women with primary breast cancer : prospective longitudinal cohort study

Background: Health-related quality of life and patient-related outcome measures for patients with cancer have gained increased interest over the last decade. However, few prospective studies with longitudinal data evaluated health-related quality of life in patients with breast cancer. This study aimed to investigate how health-related quality of life changed from the time of diagnosis to 1 year a

Occupational particle exposure and chronic kidney disease : a cohort study in Swedish construction workers

Objectives Increasing epidemiological and experimental evidence suggests that particle exposure is an environmental risk factor for chronic kidney disease (CKD). However, only a few case-control studies have investigated this association in an occupational setting. Hence, our objective was to investigate associations between particle exposure and CKD in a large cohort of Swedish construction worke

Photochemical reactivity of dissolved organic carbon in subarctic lakes along a color gradient

Lake–atmosphere carbon exchanges can be significantly affected by photochemical dissolved organic matter (DOM) mineralization. However, our understanding of how increasing allochthonous organic carbon input affects the photoreactivity of DOM per unit of absorbed incoming light is incomplete. Here, we measured the absorption of ultraviolet (UV) light and subsequent photochemical DOM decay in 148 la

A level set approach to modelling diffusional phase transformations under finite strains with application to the formation of Cu6Sn5

This paper presents a sharp interface formulation for modelling diffusional phase transformations. Grain boundary motion is, in accordance with diffusional phase transformation kinetics, determined by the amount of flux towards the interface and is formulated in a level set framework. This approach enables a computational efficiency that can be expected to be higher than what can be achieved with

Border controls and (im)mobilities : Experiences from a public transport node

The Öresund Bridge between Sweden and Denmark was opened in 2000, allowing both road traffic and fast commuter trains to travel between Malmö and Copenhagen. Various agreements have long facilitated passport-free travel. However, at the end of 2015, temporary border controls were first introduced. This paper aims to provide a deeper understanding of portrayals in the news media and everyday mobili

In-situ observations of cloud microphysics over Arabian Sea during dust transport events

The unique in situ measurements of clouds and precipitation within the shallow and deep cumulus over the north-eastern Arabian Sea region during the Indian monsoon are illustrated in this study with a focus on droplet spectral parameters. The observational period showed a significant incursion of Arabian dust and the presence of giant cloud condensation nuclei (GCCN), modifying the cloud and preci

Assessment of somatosensory profiles by quantitative sensory testing in children and adolescents with and without cerebral palsy and chronic pain

Objective: We investigated differences in somatosensory profiles (SSPs) assessed by quantitative sensory testing in children and adolescents with cerebral palsy (CCP) with and without chronic pain and compared these differences to those in a group of typically developed children and adolescents (TDC) with and without chronic pain. Method: All included subjects were consecutively recruited from and

Verbal Aspect in Synoptic Parallels : On the Method and Meaning of Divergent Tense-Form Usage in the Synoptic Passion Narratives

In Verbal Aspect in Synoptic Parallels Wally Cirafesi answers the question of why the Synoptic Gospels at times employ different tense-forms to communicate the same action. The problem has typically been explained from the perspective of redaction criticism and temporal Aktionsart approaches to the Greek verb. Cirafesi challenges these approaches by reframing the discussion in terms of recent adva

The Burden of Responsibility : Predicaments of Environmental Life in the Caraballo Mountains, Northern Philippines

Indigenous people are not obviously, or naturally, stewards of the environment. But when the idea that they are such custodians gains legal traction, and when indigenous land-use practices are codified to reflect environmental principles, they become a burden of responsibility that has significant consequences for the lives and the livelihoods of indigenous communities.This thesis is about Ikalaha

A Systematic Review of Research Gaps in the Built Environment of Inpatient Healthcare Settings

OBJECTIVE: This study utilized the evidence-gap map method and critically examined the scope, methodologies, and focus of the studies that investigated the influence of the built environment on inpatient healthcare settings over a decade (2010-2021).METHODS: We conducted a systematic review per the preferred reporting items for systematic reviews and meta-analyses guidelines and surveyed 406 artic

War inflation and taxation

Warfare has been commonly associated with increasing levels of inflation, with important implications for tax systems. In this chapter, we first review the literature on war finance and inflation, considering both the fiscal causes of inflation during wartimes and the effects of inflation on tax revenues. Second, we focus on developments in the income tax during the World Wars, building upon our p
