Alzheimer's disease (AD) is associated with atrophy of the cornu ammonis (CA) 1 and the subiculum subfield of the hippocampus (HC), and with deficits in episodic memory and spatial orientation. These deficits are mainly associated with the functionality of the posterior HC. We therefore hypothesized that key AD pathologies, i.e., β-amyloid and tau pathology would be particularly associated with th

Light-by-light scattering (γγ → γγ) is a quantum-mechanical process that is forbidden in the classical theory of electrodynamics. This reaction is accessible at the Large Hadron Collider thanks to the large electromagnetic field strengths generated by ultra-relativistic colliding lead ions. Using 480 μ1 of lead-lead collision data recorded at a centre-of-mass energy per nucleon pair of 5.02 TeV by

BACKGROUND: Due to the current world situation, Sweden has one of the highest asylum applications within the European Union. Immigrant mothers, specifically those who have immigrated during the last ten years and do not speak the language of the new country, are found to be at particular risk of being effected by postpartum depression.AIM: In this study, we elucidate Swedish Child Health Services

A contemporary trend in glacial geomorphology is the quest for a unifying theory of drumlin and ribbed moraine formation. Three Swedish example areas of each are here newly mapped, using high-resolution Light Detecting and Ranging (LiDAR) data. From previous ribbed moraine studies in these areas, we know that they formed differently, one by melt-out of stagnant debris-zonated ice, another by remou

Background: A panel of four kallikrein markers (total, free, and intact prostate-specific antigen [PSA] and human kallikrein-related peptidase 2 [hK2]) improves predictive accuracy for Gleason score ≥7 (high-grade) prostate cancer among men biopsied for elevated PSA. A four-kallikrein panel model was originally developed and validated by the Dutch center of the European Randomized Study of Screeni

The blog post discusses interactions between two different ritual, and monetary orders in a woodcarving village in northern Thailand. The first order ties together woodcarvers, traders, and buyers through the medium of several monetary currencies. People donate money in a woodcarving company to wooden figurines of Jesus, the Fo, Guanyin, Guang Gong commonly worshipped in China, and, most prominent

Study design: Cross-sectional study. Objectives: To identify socio-demographic and injury-related factors that contribute to activity limitations and participation restrictions in people with spinal cord injury (SCI) in Bangladesh. Setting: Centre for the Rehabilitation of the Paralysed (CRP), Savar, Dhaka, Bangladesh. Methods: This study involved 120 (83% men) participants with SCI; their median

Modulation from contractile to synthetic phenotype of vascular smooth muscle cells is a central process in disorders involving compromised integrity of the vascular wall. Phenotype modulation has been shown to include transition from voltage-dependent toward voltage-independent regulation of the intracellular calcium level, and inhibition of non-voltage dependent calcium influx contributes to main

The authors are involved in a project aiming at the development of a methodology for participatory modeling as a tool for public participation in water resource management. In this paper, some examples of different degrees of stakeholder influence in six key dimensions of participatory modeling are identified and discussed. Arnstein's (A ladder of citizen participation. Journal of the American Ins

While systematic literature reviews (SLRs) have contributed substantially to developing knowledge in fields such as medicine, they have made limited contributions to developing knowledge in the supply chain management domain. This is due to the ontological and epistemological idiosyncrasies of research in supply chain management, which need to be accounted for when retrieving, selecting, and synth

PURPOSE: Sclerosing epithelioid fibrosarcoma (SEF) is a highly aggressive soft tissue sarcoma closely related to low-grade fibromyxoid sarcoma (LGFMS). Some tumors display morphological characteristics of both SEF and LGFMS, so called hybrid SEF/LGFMS. Despite the overlap of gene fusion variants between these two tumor types, SEF is much more aggressive. The present study aimed to further characte

This paper presents new simple tuning rules for the gain in feedforward compensators. When the ideal feedforward controller is not possible to implement, a negative effect is introduced in the closed-loop response. So, the closed-loop transfer function from the disturbance to the error is analyzed and tuning rules for the feedforward gain are proposed. Two feedforward structures are used, a lead-l

The institution of energy consulting services is one of the several government instruments for improving the efficiency of energy usage in many European countries. Various forms of advice on energy issues are offered to households. In Sweden, there has been a drop in the number of households who avail of this service, even though it is offered independently, free of charge and easily accessible. I

Reprogramming differentiated cells towards pluripotency can be achieved by different experimental strategies including the forced expression of specific 'inducers' and nuclear transfer. While these offer unparalleled opportunities to generate stem cells and advance disease modelling, the relatively low levels of successful reprogramming achieved (1-2%) makes a direct analysis of the molecular even

Satb1 and the closely related Satb2 proteins regulate gene expression and higher-order chromatin structure of multigene clusters in vivo. In examining the role of Satb proteins in murine embryonic stem (ES) cells, we find that Satb1-/- cells display an impaired differentiation potential and augmented expression of the pluripotency determinants Nanog, Klf4, and Tbx3. Metastable states of self-renew

Differentiated cells can be reprogrammed through the formation of heterokaryons and hybrid cells when fused with embryonic stem (ES) cells. Here, we provide evidence that conversion of human B-lymphocytes towards a multipotent state is initiated much more rapidly than previously thought, occurring in transient heterokaryons before nuclear fusion and cell division. Interestingly, reprogramming of h

T cell homeostasis is largely controlled by a balance between cell death and survival and anomalies in either process account for a number of diseases linked to excessive or faulty T cell growth. Yet, the influence that cells outside the immunological system have on these processes has only recently received attention. Accumulated evidence indicate that homeostasis of the CD4+ and CD8+ T cell pool

Exchange of arguments in a discussion often makes individuals more radical about their initial opinion. This phenomenon is known as Group-induced Attitude Polarization. A byproduct of it are bipolarization effects, where the distance between the attitudes of two groups of individuals increases after the discussion. This paper is a first attempt to analyse the building blocks of information exchang
