Quantification of structures in freeze-dried materials using X-ray microtomography

The structure of a freeze-dried material is essential for its ability to preserve and protect biologics such as proteins, cells and other sensitive structures. The structure of a typical freeze-dried matrix can be described as pores surrounded by thin walls where the walls are the encapsulating material (for e.g. cells). The objective of this investigation is to evaluate X-ray microtomography (µCT

Is there evidence for a relationship between cognitive impairment and fatigue after acquired brain injury : a systematic review and meta-analysis

Purpose: Fatigue is a major symptom of ABI. Greater fatigue is associated with cognitive impairment. Our aim was to systematically review, describe and analyse the literature on the extent of this relationship. Methods: Five databases were searched from inception. Studies were included where: participants had a defined clinical diagnosis of ABI which included TBI, stroke or subarachnoid haemorrhag

Global warming is increasing the discrepancy between green (actual) and thermal (potential) seasons of temperate trees

Over the past decades, global warming has led to a lengthening of the time window during which temperatures remain favorable for carbon assimilation and tree growth, resulting in a lengthening of the green season. The extent to which forest green seasons have tracked the lengthening of this favorable period under climate warming, however, has not been quantified to date. Here, we used remote sensi

Tau-PET is superior to phospho-tau when predicting cognitive decline in symptomatic AD patients

Introduction: Biomarkers for the prediction of cognitive decline in patients with amnestic mild cognitive impairment (MCI) and amnestic mild dementia are needed for both clinical practice and clinical trials. Methods: We evaluated the ability of tau-PET (positron emission tomography), cortical atrophy on magnetic resonance imaging (MRI), baseline cognition, apolipoprotein E gene (APOE) status, pla

Total defense as a happy object : gendering mobilization of civil defense in Sweden

For the past years, the national rhetoric in Sweden has changed. Due to the Russian actions in Ukraine and Crimea, efforts towards mobilizing military and civil preparedness increased. The concept of the ‘total defence’ was reintroduced and has led to shifting priorities in Swedish politics, serving as a happy object and remedy in times of security threat and social anxiety. The article critically

Warming reshapes the invertebrate predation pressure on the plankton community

Climate change stressors, including warming and heatwaves, can alter plankton composition and dominance patterns in temperate shallow lakes, which can disrupt ecosystem function and curtail ecosystem services. Understanding how these alterations could take place under future climates is therefore important. To understand such changes, we performed a year-long mesocosm experiment with controls refl

Patients’ Perspective in Hereditary Ataxia

Hereditary ataxia represents a heterogeneous group of rare disorders with the chronic progression of motor symptoms that often become debilitating. Many forms include additional neurological, cognitive, or other symptoms. Most of these disorders lack specific treatment. We aimed to investigate aspects of patients’ quality of life, experiences, and expectations. Patients with a diagnosis of heredit

The Relationship between PDQ-8 and Costs in Parkinson's Disease—A Swedish Register-Based Study

Background: Parkinson's disease (PD) is a progressive neurodegenerative disorder associated with substantial costs which increase with progression state. However, few studies have investigated the association between costs and health related quality of life. Objectives: To estimate the relationship between costs and health related quality of life, measured by the Parkinson's disease Quality of Lif

Comparative Effectiveness of Device-Aided Therapies on Quality of Life and Off-Time in Advanced Parkinson’s Disease : A Systematic Review and Bayesian Network Meta-analysis

Introduction: Research comparing levodopa/carbidopa intestinal gel (LCIG), deep brain stimulation (DBS), and continuous subcutaneous apomorphine infusion (CSAI) for advanced Parkinson’s disease (PD) is lacking. This network meta-analysis (NMA) assessed the comparative effectiveness of LCIG, DBS, CSAI and best medical therapy (BMT) in reducing off-time and improving quality of life (QoL) in patient

Optimal stomatal theory predicts CO2 responses of stomatal conductance in both gymnosperm and angiosperm trees

Optimal stomatal theory predicts that stomata operate to maximise photosynthesis (Anet) and minimise transpirational water loss to achieve optimal intrinsic water-use efficiency (iWUE). We tested whether this theory can predict stomatal responses to elevated atmospheric CO2 (eCO2), and whether it can capture differences in responsiveness among woody plant functional types (PFTs). We conducted a me

Animal tracing with sulfur isotopes : Spatial segregation and climate variability in Africa likely contribute to population trends of a migratory songbird

Climatic conditions affect animals but range-wide impacts at the population level remain largely unknown, especially in migratory species. However, studying climate–population relationships is still challenging in small migrants due to a lack of efficient and cost-effective geographic tracking method. Spatial distribution patterns of environmental stable isotopes (so called ‘isoscapes’) generally

Which interventions contribute most to the net effect of England’s agri-environment schemes on pollination services?

Context: Agri-environment schemes support land management interventions that benefit biodiversity, environmental objectives, and other public goods. Process-based model simulations suggest the English scheme, as implemented in 2016, increased wild bee pollination services to pollinator-dependent crops and non-crop areas in a geographically heterogeneous manner. Objectives: We investigated which in

Identification of monogenic variants in more than ten per cent of children without type 1 diabetes-related autoantibodies at diagnosis in the Finnish Pediatric Diabetes Register

Aims/hypothesis: Monogenic forms of diabetes (MODY, neonatal diabetes mellitus and syndromic forms) are rare, and affected individuals may be misclassified and treated suboptimally. The prevalence of type 1 diabetes is high in Finnish children but systematic screening for monogenic diabetes has not been conducted. We assessed the prevalence and clinical manifestations of monogenic diabetes in chil

Where access and benefit-sharing comes from: A historical overview

The international legal system of access and benefit-sharing of genetic resources (or ABS) under the Convention on Biological Diversity (CBD) is an ever-evolving field as its material, temporal and activity scope is still under discussion to meet the needs of the advancement of research and development activities as well as the questions of fairness and equity that evolve with them. Activities, su

The functional potential of methane producing and consuming microorganisms in a changing world : Den funktionella potentialen hos mikroorganismer som producerar och förbrukar metan i en föränderlig värld.

It’s clear that human activities have heated our climate via the release of anthropogenic greenhouse gases. Recent changes within the earth climate are rapid, intensifying, and unprecedented. With each additional increment of warming, climate change is impacting ecosystems through changes in average conditions, climate variability, coupled with other associated changes such as biodiversity loss an

Adherence to the EAT-Lancet diet, genetic susceptibility, and risk of type 2 diabetes in Swedish adults

BACKGROUND AND AIMS: In 2019, the EAT-Lancet Commission proposed a mainly plant-based diet that nurtures human health and supports environmental sustainability. However, its association with type 2 diabetes (T2D) has not been widely studied, and it remains unclear whether genetic susceptibility for T2D can modify this association. The aim was therefore to investigate the association between the EA

Starch intake, amylase gene copy number variation, plasma proteins, and risk of cardiovascular disease and mortality

BACKGROUND: Salivary amylase, encoded by the AMY1 gene, initiate the digestion of starch. Whether starch intake or AMY1 copy number is related to disease risk is currently rather unknown. The aim was to investigate the association between starch intake and AMY1 copy number and risk of cardiovascular disease (CVD) and mortality and whether there is an interaction. In addition, we aim to identify CV

Decision analytic approach for the reclassification of concrete bridges by using elastic limit information from proof loading

Reclassification of bridges, i.e., a change in load rating, using reliability-based methods and a direct update with proof load information has been presented by many authors. However, bridge reclassification has hardly been studied from a decision analytic perspective, i.e., with quantification of the risks and benefits of different classification choices, and the expected benefit gain from proof
