Searching for novel cerebrospinal fluid biomarkers of tau pathology in frontotemporal dementia : An elusive quest
Background Frontotemporal dementia (FTD) is a pathologically heterogeneous neurodegenerative disorder associated usually with tau or TDP-43 pathology, although some phenotypes such as logopenic variant primary progressive aphasia are more commonly associated with Alzheimer's disease pathology. Currently, there are no biomarkers able to diagnose the underlying pathology during life. In this study,
Longitudinal tau and metabolic PET imaging in relation to novel CSF tau measures in Alzheimer’s disease
Purpose: Studies comparing CSF and PET tau biomarkers have included only commercial CSF assays examining specific phosphorylation sites (e.g. threonine 181, P-tau 181p ) and mid-domain tau (i.e. total tau, T-tau). Moreover, these studies did not examine CSF tau levels in relation to cerebral glucose metabolism. We thus aimed to examine CSF tau measures, using both commercial and novel assays, in
No diurnal variation of classical and candidate biomarkers of Alzheimer's disease in CSF
Background: Cerebrospinal fluid (CSF) biomarkers have gained increasing importance in the diagnostic work-up of Alzheimer's disease (AD). The core CSF biomarkers related to AD pathology (Aβ42, t-tau and p-tau) are currently used in CSF diagnostics, while candidate markers of amyloid metabolism (Aβ38, Aβ40, sAPPα, sAPPβ), synaptic loss (neurogranin), neuroinflammation (YKL-40), neuronal damage (VIL
Preanalytical confounding factors in the analysis of cerebrospinal fluid biomarkers for Alzheimer's disease : The issue of diurnal variation
Given the growing use of cerebrospinal fluid (CSF) beta-amyloid (Aß) and tau as biomarkers for early diagnosis of Alzheimer's disease (AD), it is essential that the diagnostic procedures are standardized and the results comparable across different laboratories. Preanalytical factors are reported to be the cause of at least 50% of the total variability. Among them, diurnal variability is a key issu
Value of cerebrospinal fluid α-synuclein species as biomarker in Parkinson's diagnosis and prognosis
Since diagnosis of Parkinson's disease (PD) is mostly based on clinical criteria, it is almost impossible to formulate an early diagnosis, as well as a timely differential diagnosis versus other parkinsonisms. A great effort in searching reliable biomarkers both for early diagnosis and prognosis in PD is currently ongoing. Cerebrospinal fluid has been widely investigated as potential source for su
Apolipoprotein A-I in glucose metabolism and amyloidosis
The role of Apolipoprotein A-I (ApoA-I), the main protein component of HDL, in cholesterol transport and metabolism is well known and has been studied for more than four decades. More recently, ApoA-I protein has been shown to also have a positive role in glucose control by both stimulation of glucose uptake by muscles and by increasing glucose-stimulated pancreatic insulin secretion. Two of the f
The Challenges of Assurance on Non-financial Reporting
The purpose of this paper is to enhance our understanding of the notions and conceptual foundations of assurance in the standard setting arena. This will facilitate an informed discussion of the challenges and the role of assurance within an increasingly complex and fragmented corporate reporting regulatory landscape. The study draws on relevant literature on sustainability assurance and an analys

The Crisis of Care - Caring Against Crisis : Professional Responses to Austerity Politics in Female Dominated Welfare Professions
Capitalist crises, such as the current financial crisis, are also crises in the sphere of social reproduction, according to Fraser (2014). In the current phase of financialized capitalism, social reproduction is increasingly treated as a commodity. As many feminist- and gender scholars have showed, this has resulted in increased pressures on women’s labour. During the last ten years, the Nordic co
The rise of Integrated Reporting in the Public Sector : An analysis of transnational governance interactions
Integrated Reporting (IR) in the public sector has been put forward as a framework to help public sector entities address diverse accountability requirements while gaining a greater understanding of the ways in which they create value. This chapter has a strong focus on understanding the emergence of IR in the public sector through a multi-stakeholder approach and a governance perspective. The cha
Improving the quality of healthcare through interdisciplinary education - a collaboration between Medicine and Gender Studies
While Gender studies has sometimes been placed in opposition to biomedicine and medical practices in public debate, there is increasing scholarly recognition of the relevance of social factors and relationships for biological and medical phenomena and for the quality and equity of healthcare practices. In Sweden and internationally, medical schools have identified the need to integrate approaches While Gender studies has sometimes been placed in opposition to biomedicine and medical practices in public debate, there is increasing scholarly recognition of the relevance of social factors and relationships for biological and medical phenomena and for the quality and equity of healthcare practices (Chin et al., 2016; Meloni, Cromby, Fitzgerald, & Lloyd, 2018; SKL, 2014). In Sweden and int
Scheduling conflicts in the low-wage labor force: the case of Swedish and US women
By comparing the work-hours-related experiences of women in two countries that differ in their labor protections and their social-service provision—in other words, that differ in the extent to which neoliberalism holds sway—this manuscript sheds light on the implications of neoliberalism in terms of women’s working conditions.Specifically, we analyze the protections offered by each country that co

Recurrant collection of Drosophila melanogaster from wild African environments and genomic insights into species history
A long-standing enigma concerns the geographic and ecological origins of the intensively studied vinegar fly, Drosophilamelanogaster. This globally distributed human commensal is thought to originate from sub-Saharan Africa, yet untilrecently, it had never been reported from undisturbed wilderness environments that could reflect its precommensalniche. Here, we document the collection of 288 D. mel
Cerebrospinal fluid in Alzheimer's : A precious tool
Simultaneous X-ray Video-Fluoroscopy and Pulsed Ultrasound Velocimetry Analyses of the Pharyngeal Phase of Swallowing of Boluses with Different Rheological Properties
The Ultrasound Velocity Profiling (UVP) technique allows real-time, non-invasive flow mapping of a fluid along a 1D-measuring line. This study explores the possibility of using the UVP technique and X-ray video-fluoroscopy (XVF) to elucidate the deglutition process with the focus on bolus rheology. By positioning the UVP probe so that the pulsed ultrasonic beam passes behind the air-filled trachea
What are natural concepts? A design perspective.
Conceptual spaces have become an increasingly popular modeling tool in cognitive psychology. The core idea of the conceptual spaces approach is that concepts can be represented as regions in similarity spaces. While it is generally acknowledged that not every region in such a space represents a natural concept, it is still an open question what distinguishes those regions that represent natural co
