Background: Speech impairments are an early feature of Alzheimer’s disease (AD) and consequently, analysing speech performance is a promising new digital biomarker for AD screening. Future clinical AD trials on disease modifying drugs will require a shift to very early identification of individuals at risk of dementia. Hence, digital markers of language and speech may offer a method for screening

Analytical chemistry is a sub-discipline of chemistry that even young schoolchildren encounter at an early stage in their education. Gravimetry and measurement uncertainties are aspects that form a part of such education, as well as measurements of pH and colorimetry. These are all an integral part of children’s early educational experiences, which shows the importance of this discipline within th

Background Direct cell reprogramming is characterized by the use of defined factors to rewire the transcriptional and epigenetic network of one cell-type into one of a different lineage. We have recently identified the transcription factors PU.1, IRF8, and BAFT3 (PIB) as sufficient to induce a type 1 conventional dendritic cell (cDC1) fate in both somatic and cancer cells.1,2 cDC1 is a rare dendri

Early detection of Alzheimer's disease is essential to develop preventive treatment strategies. Detectible change in brain volume emerges relatively late in the pathogenic progression of disease, but microstructural changes caused by early neuropathology may cause subtle changes in the MR signal, quantifiable using texture analysis. Texture analysis quantifies spatial patterns in an image, such as

Osteoarthritis (OA) is the most common form of arthritis and often causes pain and functional impairment. Despite its high burden on society, knowledge about the occurrence of OA and its associated mortality is sparse. The epidemiology of OA is difficult to determine due to the patients’ fluctuating symptoms and challenges in detecting and defining the radiographic disease. The specific aims of th

The success of social movements is highly dependent on their sustainability, as in their efforts to produce meaningful change, they inevitably encounter oppressive dominant forces. With the advent of the social media era, scholarly research on collective action has acquired an additional dimension, bringing the role of their communicative constitution to the forefront of discussions. However, a de

The 2015 Paris Agreement of the United Nations Framework Convention on Climate Change aims to keep global average temperature increases well below 2 °C of preindustrial levels in the Year 2100. Vital to its success is achieving a decrease in the abundance of atmospheric methane (CH4), the second most important anthropogenic greenhouse gas. If this reduction is to be achieved, individual nations mu

In order to better assess the role of agriculture within the global climate-vegetation system, we present a model of the managed planetary land surface, Lund-Potsdam-Jena managed Land (LPJmL), which simulates biophysical and biogeochemical processes as well as productivity and yield of the most important crops worldwide, using a concept of crop functional types (CFTs). Based on the LPJ-Dynamic Glo

Hänsyn till biologisk mångfald viktigt vid skogsbränsleuttag Situationen för den biologiska mångfalden i skogen är allvarlig och att plocka ut skogsbränsle kan bidra till ytterligare försämringar. Hänsyn till biologisk mångfald vid skogsbränsleuttag är därför mycket viktig och det går faktiskt att anpassa skogsbränsleuttaget så att den negativa påverkan blir så liten som möjligt. Skogsbränsle ärThis study aims to investigate how the biodiversity in forests in southern Sweden is affected by extraction of forest fuel and to identify what can be done to preserve the biodiversity while extracting forest fuel. The study is performed on behalf of the energy company Kraftringen, which buys large amounts of forest fuel every year. Firstly, a literature study on how biodiversity in forests is af

I denna studie har det huvudsakliga syftet varit att undersöka hur de danska diftongerna i det fonologiska inventariet realiseras fonetiskt. De primära faktorer som har studerats är dels hur öppningsdiftongernas respektive slutningsdiftongernas "bana" ser ut, dels vilken variation det finns beroende på hur diftongen börjar eller slutar, dvs om t.ex [w]-läget kommer att uppnås oberoende a

Land remediation is an important part of restoration measures after a radioactive fallout containing long-lived fission products such as 137Cs. In this multidisciplinary study, we focused on three main issues related to remediation of contaminated urban areas. First, we assessed how much decontamination contributes to reducing resident radiation exposure and how much this reduction depends on the

Att mäta framgång i byggprojekt idag kan vara svårt. Dels att hitta en samsyn på vad framgång är dels hur man ska mäta framgång. Genom den forskning som finns inom området kan man konstatera att det är äldre metoder som används än idag för att mäta framgång. Dessa metoder har även modifierats med tiden och bildat nya metoder. De vanligaste områdena att mäta för att förstå framgång i forskning är tMeasuring success in construction projects today can be difficult—partly due to the lack of consensus on what success is, and partly due to the challenge of how to measure it. Existing research shows that older methods are still used to measure success, though many of these have been modified over time and evolved into new approaches. The most common aspects evaluated in research when measuring su

The discovery of the CRISPR-Cas9 system has revolutionized several areas of biological research by making genome engineering easy, affordable, fast, accessible and scalable. One field that has not yet benefited from this technological advance is that of mitochondrial DNA research. Study I addresses the challenges associated with adapting CRISPR-Cas9 to the mitochondrial environment, and identifies

In Europe, willow (Salix spp.) trees have been used commercially since the 1980s at a large scale to produce renewable energy. While reducing fossil fuel needs, growing short rotation coppices (SRCs), such as poplar or willow, may have a high impact on local air quality as these species are known to produce high amounts of isoprene, which can lead to the production of tropospheric ozone (O3). Here

Acute myeloid leukemia (AML) is a highly heterogeneous blood disease which is characterized by different mutations and chromosomal rearrangements. Nearly 60% of genetic alterations have been found in AML patients involve in signaling pathways including signaling of tyrosine kinase receptor FLT3. FLT3 mutations emerged as one of the most common mutations in AML which represent around 35% of all AML

Inflammatory airway diseases and lower respiratory tract infections are leading causes of severe illness, disability and death worldwide. Much of today´s hypotheses about the underlying inflammatory processes and pathogenic contribution by immune cells come from in vitro experiments or animal models. As a consequence, our knowledge of the actual immunopathological events in real patient tissues is

Pulchrol, a natural compound isolated from the roots of the vegetal specie Bourreria pulchra has been shown to possess potential antiparasitic activity toward Trypanosomatids, particularly against Trypanosoma cruzi, which causes the Chagas disease; and moderately against Leishmania species, responsible for Leishmaniasis. In this investigation, several pulchrol analogues were prepared and assayed t

Aim: The Eurasian otter (Lutra lutra) is a flagship species for global freshwater ecosystems. As one of the most widely distributed Palearctic mammals, the otter used to inhabit most provinces in China. However, after decades of relentless hunting and habitat degradation, the Sanjiangyuan Region is now one of last strongholds for this species in China. Currently, there still remains an enormous kn
