Urban freight logistics is a growing phenomenon in cities and contributes to the wealth of citizens and businesses in urban areas. But it also has negative side effects such as emissions, congestion, and accidents, which eradicate some of their benefits for society. The current development of urban freight logistic activities is unsustainable. A more sustainable path of development is needed but i

Saliva plays a crucial role in maintaining oral health through its physical and chemical properties that provide various protective functions. One of its essential components is the human host defense peptide LL-37, which is produced by immune cells and epithelial cells, and participates in the first line of defense against pathogens. LL-37 is a potent antimicrobial agent against both gram-positiv

Under de senaste åren har det skett en förskjutning i forskningen från att försöka förstå vem som löper risk att bli radikaliserad, till att undersöka vad som gör att vissa individer har större benägenhet att bli radikaliserad. Känslor av exkludering, diskriminering och marginalisering har tidigare kopplats till extremistiska handlingar. Trots det finns det få empiriska studier som utforskar sambaThe present thesis aims to examine the causal role of social exclusion within theradicalization process and further to explore moderating and mediating factors. In recent years there has been a move away from trying to understand who is at risk of becoming an extremist, to exploring what makes someone at risk. Feelings of exclusion, discrimination and marginalization have all been linked to partic

The intestinal lamina propria contains a diverse network of fibroblasts that provide key support functions to cells within their local environment. Despite this, our understanding of the diversity, location and ontogeny of fibroblasts within and along the length of the intestine remains incomplete. Here we show that the small and large intestinal lamina propria contain similar fibroblast subsets t

This book discusses the importance of developing routininized behaviours in new venture development, specifically highlighting the unique challenges that academic spin-offs face in this vital step towards successful business creation. During the early development stage, new ventures are informally established and have few routines that inform organizational performance. However, the process of new

This gait biomechanics study investigated stride length (SL), stride duration (SDN), the peak values of ground reaction forces (GRFspeak), required coefficient of friction (RCOFpeak), leg joints’ angles (anglepeak), angular velocity (angvelx.peak), angular acceleration (angaccx.peak), minimum angle (anglemin.) of the foot, and muscles’ electromyography (EMG) during the stance phase (SP) of the dom

While personal data is invaluable to firms, the drivers of e-commerce customers' willingness to disclose their personal data remain tenuous. Using social exchange theory, we develop a model that explores the impact of consumers' perceived benefit, and relative power, on store trust, in turn driving their willingness to disclose their personal data. We collected our empirical data using a represent

A viewpoint about the importance of ethnicity in medical research.

IntroductionMild parkinsonian signs (MPS) have been characterized by several definitions, using the motor part of the Unified Parkinson's Disease Rating Scale (UPDRS). We aimed to investigate the prevalence of MPS and their association with functional level and comorbidities in the oldest old.MethodCommunity-dwelling older adults (n = 559, median age 85, range 80–102 years) were examined regarding

Purpose: To assess the extent of demyelination in cervical spondylotic myelopathy (CSM) using myelin water imaging (MWI) and electrophysiologic techniques.Methods: Somatosensory evoked potentials (SSEPs) and MWI were acquired in 14 patients with CSM and 18 age-matched healthy controls. MWI was performed on a 3.0T whole body magnetic resonance scanner. Myelin water fraction (MWF) was extracted for

PurposeMyelin water imaging (MWI) using multi-echo T2 relaxation is a quantitative MRI technique that can be used as an in vivo biomarker for myelin in the central nervous system. MWI using a multi-echo spin echo sequence currently takes more than 20 min to acquire eight axial slices (5 mm thickness) in the cervical spinal cord, making spinal cord MWI impractical for implementation in clinical stu

Technological developments now make it possible to employ many markers for many individuals in a phylogeographic setting, even for taxa with large and complex genomes such as salamanders. The banded newt (genus Ommatotriton) from the Near East has been proposed to contain three species (O. nesterovi, O. ophryticus and O. vittatus) with unclear phylogenetic relationships, apparently limited intersp

Speciation entails a reduction in gene flow between lineages. The rates at which genomic regions become isolated varies across space and time. Barrier markers are linked to putative genes involved in (processes of) reproductive isolation, and, when observed over two transects, indicate species-wide processes. In contrast, transect-specific putative barrier markers suggest local processes. We studi

Theoretical and empirical studies suggest that the structure and position of hybrid zones can change over time. Evidence for moving hybrid zones has been directly inferred by repeated sampling over time, or indirectly through the detection of genetic footprints left by the receding species and the resulting asymmetric patterns of introgression across markers. We here investigate a hybrid zone form

Myelin water imaging can be achieved using multicomponent T2 relaxation analysis to quantify in vivo measurement of myelin content, termed the myelin water fraction (MWF). Therefore, myelin water imaging can be a valuable tool to better understand the underlying white matter pathology in demyelinating diseases, such as multiple sclerosis. To apply myelin water imaging in multisite studies and clin

Quantitative magnetic resonance imaging (MRI) techniques have been developed as imaging biomarkers, aiming to improve the specificity of MRI to underlying pathology compared to conventional weighted MRI. For assessing the integrity of white matter (WM), myelin, in particular, several techniques have been proposed and investigated individually. However, comparisons between these methods are lacking

BACKGROUND AND PURPOSEMyelin water imaging (MWI) is a magnetic resonance imaging technique that quantifies myelin in-vivo. Although MWI has been extensively applied to study myelin-related diseases in groups, clinical use in individual patients is challenging mainly due to population heterogeneity. The purpose of this study was twofold: (1) create a normative brain myelin water atlas depicting the

BACKGROUND AND PURPOSEAcquiring and interpreting quantitative myelin-specific MRI data at an individual level is challenging because of technical difficulties and natural myelin variation in the population. To overcome these challenges, we used multiecho T2 myelin water imaging (MWI) to create T2 metric healthy population atlases that depict the mean and variation of myelin water fraction (MWF), a
