Postmortem Human Dura Mater Cells Exhibit Phenotypic, Transcriptomic and Genetic Abnormalities that Impact their Use for Disease Modeling

Patient-derived cells hold great promise for precision medicine approaches in human health. Human dermal fibroblasts have been a major source of cells for reprogramming and differentiating into specific cell types for disease modeling. Postmortem human dura mater has been suggested as a primary source of fibroblasts for in vitro modeling of neurodegenerative diseases. Although fibroblast-like cell

Antibody-free measurement of cerebrospinal fluid tau phosphorylation across the Alzheimer's disease continuum

BACKGROUND: Alzheimer's disease is characterized by an abnormal increase of phosphorylated tau (pTau) species in the CSF. It has been suggested that emergence of different pTau forms may parallel disease progression. Therefore, targeting multiple specific pTau forms may allow for a deeper understanding of disease evolution and underlying pathophysiology. Current immunoassays measure pTau epitopes

Blame as a sentiment

The nature of blame is not to be identified solely with a judgment, or an overt act, or an angry emotion. Instead, blame should be identified with a sentiment: more specifically, a multi-track disposition that manifests itself in various different emotions, thoughts or actions in a range of different circumstances. This paper aims to argue for these two claims. I start by arguing that blame is not

Asking About “Prostitution”, “Sex Work” and “Transactional Sex” : Question Wording and Attitudes Toward Trading Sexual Services

This study explored the impact of question wording on attitudes toward trading sexual services. There are no previous research agendas investigating how views on the trade in sex are susceptible to question word choice. We utilized an original survey to assess how three different concepts used to represent the exchange of sexual services impact on the reported level of acceptability among responde

Photophysical Integrity of the Iron(III) Scorpionate Framework in Iron(III)-NHC Complexes with Long-Lived 2LMCT Excited States

Fe(III) complexes with N-heterocyclic carbene (NHC) ligands belong to the rare examples of Earth-abundant transition metal complexes with long-lived luminescent charge-transfer excited states that enable applications as photosensitizers for charge separation reactions. We report three new hexa-NHC complexes of this class: [Fe(brphtmeimb)2]PF6(brphtmeimb = [(4-bromophenyl)tris(3-methylimidazol-2-yl

External Validation of the Ovarian-Adnexal Reporting and Data System (O-RADS) Lexicon and the International Ovarian Tumor Analysis 2-Step Strategy to Stratify Ovarian Tumors Into O-RADS Risk Groups

IMPORTANCE: Correct diagnosis of ovarian cancer results in better prognosis. Adnexal lesions can be stratified into the Ovarian-Adnexal Reporting and Data System (O-RADS) risk of malignancy categories with either the O-RADS lexicon, proposed by the American College of Radiology, or the International Ovarian Tumor Analysis (IOTA) 2-step strategy.OBJECTIVE: To investigate the diagnostic performance

Teacher-to-Classroom Assignment and Student Achievement

We study the effects of counterfactual teacher-to-classroom assignments on average student achievement in U.S. elementary and middle schools. We use the Measures of Effective Teaching (MET) experiment to semiparametrically identify the average reallocation effects (AREs) of such assignments. Our identification strategy exploits the random assignment of teachers to classrooms in MET schools. To acc

Interactive Interventions can Improve Hand Hygiene and Aseptic Techniques During Perioperative Care – Experience From the “Safe Hands” Project

Purpose: This paper evaluates a theory-driven, interactive hand hygiene (HH) intervention, the Safe Hands project, based on theories of organizational learning and culture including leadership support, dialogue and co-creation. Design: This prospective quasi-experimental study used unobtrusive overt observations to evaluate adherence to HH recommendations after implementing an infection-prevention

The prototyping of a high-resolution neutron activation analysis system - Based on a Pelletron accelerator and fast pneumatic sample-transport

A new neutron activation analysis system is currently being designed at Lund University. The design incorporates a compact accelerator driven neutron source, based on a 3 MV Pelletron accelerator and a pneumatic sample conveyor to transport samples from the neutron source to a measurement station consisting of an array of high-purity Ge γ-ray detectors. A prototype for this new station is currentl

Etik, autenticitet och det språkliga autentiska tecknet

Följande text syftar till att belysa frågan om etik och dess relation till autenticitet (respektive inautenticitet) med tilläggsfrågan om språkets betydelse för förståelsen av den ordlösa erfarenheten i det autentiska mötet mellan ett ”jag” och ett ”du” utifrån framför allt den fransk-litauiske filosofen Emmanuel Levinas (1906–1995) ansikte-mot-ansikte- etik. Frågan om jagets förhållande till den

MANAGEMENT TOOLS FOR BUSINESS MODEL INNOVATION–A REVIEW

The purpose of this chapter is to identify and classify proposed business model innovation tools through a literature review of academic publications. We classified the tools into three categories: innovation process stage, strategic objective and size of firm. Our main findings are that the overall number of business model innovation (BMI) tools described in the research literature is limited mos

Compositionally graded channel HEMTs towards improved linearity for low-noise RF amplifiers

Although AlGaN/GaN HEMTs with high power and current gain have been demonstrated in RF device applications, at high signal operation they show an inherent non-linear behavior which leads to gain compression and signal distortion. Polarization-doped AlGaN/GaN HEMTs, with a compositionally graded channel enables a linear response improvement through formation of a 3-D electron gas. In this work, we

Template-Assisted Selective Epitaxy of InAs on W

Results on integration of InAs on W films through template assisted selective epitaxy are presented. The InAs crystals are analysed using SEM, electron beam backscattering and in-situ electrical measurements. A high yield of single crystalline InAs can be obtained for certain template diameters and pitches which demonstrates that this is a viable route to integrate III-V semiconductors in the back

Ämnesspråk i skolämnet Idrott och hälsa : En analys av begrepp och begreppsrelationer

Flera idrottsforskare understryker språkets roll i undervisning i skolämnet Idrott och hälsa (Larsson & Karlefors, 2015; Nyberg & Larsson, 2014; Schenker et al., 2019), och ämnesspråket har påståtts vara svagt inte minst i de delar som hör samman med hälsa (Redelius et al., 2009; Schenker, 2018). I denna artikel presenteras resultaten av en pilotstudie av ämnesspråket i skolämnet Idrott oc
