Chronic stress and poor sleeping habits are associated with self-reported IBS and poor psychological well-being in the general population

OBJECTIVE: The present population-based study aimed to examine the association of chronic stress and sleeping difficulties with self-reported irritable bowel syndrome (IBS), gastrointestinal (GI) symptoms past 2 weeks, and psychological well-being.RESULTS: The Malmö Offspring Study included subjects from the general population to complete a questionnaire regarding sociodemographic factors, lifesty

Neoadjuvant Trastuzumab, Pertuzumab, and Docetaxel vs Trastuzumab Emtansine in Patients with ERBB2-Positive Breast Cancer : A Phase 2 Randomized Clinical Trial

Importance: Trastuzumab emtansine (T-DM1) is presently approved for treatment of advanced breast cancer and after incomplete response to neoadjuvant therapy, but the potential of T-DM1 as monotherapy is so far unknown. Objective: To assess pathologic complete response (pCR) to standard neoadjuvant therapy of combination docetaxel, trastuzumab, and pertuzumab (DTP) vs T-DM1 monotherapy in patients

Arctic-adapted dogs emerged at the Pleistocene–Holocene transition

Although sled dogs are one of the most specialized groups of dogs, their origin and evolution has received much less attention than many other dog groups. We applied a genomic approach to investigate their spatiotemporal emergence by sequencing the genomes of 10 modern Greenland sled dogs, an ~9500-year-old Siberian dog associated with archaeological evidence for sled technology, and an ~33,000-ye

The Politics and Ethics of Representation in Qualitative Research

This book offers insights on politics and ethics of representation that are relevant to researchers concerned with struggles for justice. It takes moments of discomfort in the qualitative research process as important sites of knowledge for exploring representational practices in critical research.The Politics and Ethics of Representation in Qualitative Research draws on experiences from research

Depressive symptoms postpartum is associated with physical activity level the year prior to giving birth - A retrospective observational study

OBJECTIVES: To examine physical activity level prior to pregnancy, during pregnancy and postpartum and investigate the association with depressive symptoms postpartum among women in Sweden.STUDY DESIGN: Retrospective observational study including 532 women on self-assessment of physical activity level before pregnancy, during pregnancy and postpartum, depressive symptoms postpartum as well as stre

Reindeer grazing history determines the responses of subarctic soil fungal communities to warming and fertilization

Composition and functioning of arctic soil fungal communities may alter rapidly due to the ongoing trends of warmer temperatures, shifts in nutrient availability and shrub encroachment. In addition, the communities may also be intrinsically shaped by heavy grazing, which may locally induce an ecosystem change that couples with increased soil temperature and nutrients and where shrub encroachment i

Artificial intelligence and the medical physics profession : a Swedish perspective

BackgroundThere is a continuous and dynamic discussion on artificial intelligence (AI) in present-day society. AI is expected to impact on healthcare processes and could contribute to a more sustainable use of resources allocated to healthcare in the future. The aim for this work was to establish a foundation for a Swedish perspective on the potential effect of AI on the medical physics profession

National First Peoples Gathering on Climate Change

Our purpose in hosting the National First Peoples Gathering on Climate Change (the Gathering) was to celebrate, learn from and enhance First Peoples-led climate action. We set out to strengthen kinships, cultural identity and well-being, and to strengthen caring for Country by using both Indigenous and scientific knowledge. The Gathering supported this overall purpose through five aims:• Bring Tra

Uncertainty modelling in metamodels for fire risk analysis

In risk-related research of fire safety engineering, metamodels are often applied to approximate the results of complex fire and evacuation simulations. This approximation may cause epistemic uncertainties, and the inherent uncertainties of evacuation simulations may lead to aleatory uncertainties. However, neither the epistemic ‘metamodel uncertainty’ nor the aleatory ‘inherent uncertainty’ have

Reconstructing Stress Resultants in Wind Turbine Towers Based on Strain Measurements

Support structures of offshore wind turbines are subject to cyclic stresses generated by different time-variant random loadings such as wind, waves, and currents in combination with the excitation by the rotor. In the design phase, the cyclic demand on wind turbine support structure is calculated and forecasted with semi or fully probabilistic engineering models. In some cases, additional cyclic s

Temporality of agency in regional development

The temporality of agency plays a fundamental role in regional development but has received little attention in economic geography and regional studies. This paper zooms in on two aspects of temporality: the temporality of intentions and the temporality of consequences. The former refers to actors’ perception and valuation of opportunities in the near and distant future, whereas the latter refers

"Det handlar om vår framtid" : Hur elevers scientific literacy kan utvecklas genom SNI-argumentation i kemiundervisning

En individ i dagens samhälle kommer ständigt i kontakt med olika frågor som är kopplade till naturvetenskap. Val ska göras, beslut ska fattas. Ska jag vaccinera mig? Ska jag köpa den där vattentäta jackan? Vilket elbolag ska jag välja? Vilken fisk ska jag köpa? Ska jag skänka pengar till eller engagera mig i en miljöorganisation? Medborgare i ett demokratiskt samhälle behöver kunskaper som gör att

Dyslexia Candidate Gene and Ciliary Gene Expression Dynamics During Human Neuronal Differentiation

Developmental dyslexia (DD) is a neurodevelopmental condition with complex genetic mechanisms. A number of candidate genes have been identified, some of which are linked to neuronal development and migration and to ciliary functions. However, expression and regulation of these genes in human brain development and neuronal differentiation remain uncharted. Here, we used human long-term self-renewin

p53 controls genomic stability and temporal differentiation of human neural stem cells and affects neural organization in human brain organoids

In this study, we take advantage of human induced pluripotent stem (iPS) cell-derived neural stem cells and brain organoids to study the role of p53 during human brain development. We knocked down (KD) p53 in human neuroepithelial stem (NES) cells derived from iPS cells. Upon p53KD, NES cells rapidly show centrosome amplification and genomic instability. Furthermore, a reduced proliferation rate,

Humanized Stem Cell Models of Pediatric Medulloblastoma Reveal an Oct4/mTOR Axis that Promotes Malignancy

Medulloblastoma (MB), the most frequent malignant childhood brain tumor, can arise from cellular malfunctions during hindbrain development. Here we generate humanized models for Sonic Hedgehog (SHH)-subgroup MB via MYCN overexpression in primary human hindbrain-derived neuroepithelial stem (hbNES) cells or iPSC-derived NES cells, which display a range of aggressive phenotypes upon xenografting. iP

Single-cell study of neural stem cells derived from human iPSCs reveals distinct progenitor populations with neurogenic and gliogenic potential

We used single-cell RNA sequencing (seq) on several human induced pluripotent stem (iPS) cell-derived neural stem cell (NSC) lines and one fetal brain-derived NSC line to study inherent cell type heterogeneity at proliferating neural stem cell stage and uncovered predisposed presence of neurogenic and gliogenic progenitors. We observed heterogeneity in neurogenic progenitors that differed between

The T-type Ca2+ Channel Cav3.2 Regulates Differentiation of Neural Progenitor Cells during Cortical Development via Caspase-3

Here we report that the low-voltage-dependent T-type calcium (Ca2+) channel Cav3.2, encoded by the CACNA1H gene, regulates neuronal differentiation during early embryonic brain development through activating caspase-3. At the onset of neuronal differentiation, neural progenitor cells exhibited spontaneous Ca2+ activity. This activity strongly correlated with the upregulation of CACNA1H mRNA. Cells
