A major unanswered question in the dementia field is whether cognitively unimpaired individuals who harbor both Alzheimer's disease neuropathological hallmarks (that is, amyloid-β plaques and tau neurofibrillary tangles) can preserve their cognition over time or are destined to decline. In this large multicenter amyloid and tau positron emission tomography (PET) study (n = 1,325), we examined the
Interferon gamma (IFNγ) is central to the inflammatory immune response, such as that entrained by BCG immunotherapy for bladder cancer. However, immune-mediated tumour cell killing is subject to modulation by immunoinhibitory “checkpoint” receptors such as PD-L1. We investigated the effects of IFNγ on barrier-forming in vitro-differentiated normal human urothelium using mRNA-sequencing, and showed
Thick GaN layers with a low concentration of defects are the key to enable next-generation vertical power electronic devices. Here, we explore hot-wall metalorganic chemical vapor deposition (MOCVD) for the development of GaN homoepitaxy. We propose a new approach to grow high-quality homoepitaxial GaN in N2-rich carrier gas and at a higher supersaturation as compared to heteroepitaxy. We develop
We have developed a direct immunofluorescence technique utilising chelates of the lanthanide ions europium and terbium conjugated to monoclonal IgGs (Mabs) against prostate-specific antigen (PSA) and alpha-1- antichymotrypsin (ACT) for the detection and quantification on the same tissue section. Strong signals without disturbance from tissue autofluorescence were demonstrated in paraffin sections
Purpose Pretreatment prostate-specific antigen (PSA) dynamics (PSA velocity and PSA doubling time) are widely advocated as useful prognostic markers in prostate cancer. We aimed to assess the published evidence for the clinical utility of PSA dynamics in this population. Methods We conducted a systematic review of studies published before March 2007 in which a PSA dynamic (velocity or doubling tim
Objectives: The introduction of time-dependent reperfusion therapies in acute ischemic stroke has increased the need for early identification. We explore the safety and feasibility of STROKE ALARM which detects sudden arm paresis, the most frequent symptom in stroke. Materials and methods: Consecutive patients admitted with a stroke or TIA at Skåne University Hospital were screened according to in
Appropriate evaluation and experimental design are fundamental for empirical sciences, particularly in data-driven fields. Due to the successes in computational modeling of languages, for instance, research outcomes are having an increasingly immediate impact on end users. As the gap in adoption by end users decreases, the need increases to ensure that tools and models developed by the research co
Makerspaces are shared workshops for the public to design, innovate and prototype. These spaces are primarily located in the urban regions and provide access to 'high-tech' and traditional low-tech tools needed for innovation design. Though makerspaces are a western phenomenon, their emergence in India can be traced to the early decade of the 2010s. In this paper, we study the urban makerspaces in
Importance: The behavioral variant of Alzheimer disease (bvAD) is characterized by early and predominant behavioral deficits caused by AD pathology. This AD phenotype is insufficiently understood and lacks standardized clinical criteria, limiting reliability and reproducibility of diagnosis and scientific reporting. Objective: To perform a systematic review and meta-analysis of the bvAD literature
To date, the best daylighting assessment technique is provided by climate-based simulation tools, which require remarkable efforts to create and calibrate realistic models. The data-driven approaches represent an interesting opportunity to support the physics-based modelling. This work proposes a novel method aimed at the optimization of energy use and luminous environment for a set of lighting co
We present updated NLO predictions for the electroweak t-channel production of heavy quarks at the Tevatron and at the LHC. We consider production of single top and fourth generation t′ starting from both 2 → 2 and 2→3 Born processes. Predictions for tb′ and t′b′ cross sections at NLO are also given for the first time. A thorough study of the theoretical uncertainties coming from parton distributi
Venous compliance in the calf of humans and its importance for capacitance function in relation to age were studied with the aid of 22, 44, and 59 mmHg lower body negative pressure (LBNP). Negative pressure transmission to the calf as well as changes in calf volume were studied, and venous compliance was calculated [change in volume with pressure change (dV/dP)]. The change in capacitance response
Although researchers across the social sciences speak of a linguistic turn, most research exploring culture still assumes a traditional perspective on language, which conceives meaning as representation. Yet, Wittgenstein convincingly criticized the epistemological basis of such a perspective, offering an alternative view on language. The paper begins by explaining the central points of a performa
AimThe aim was an in‐depth exploration of uncertainty and self‐efficacy among parents of a child with congenital cataract by means of two theoretical frameworks to re‐design family care.DesignA directed content analysis in accordance with Hsieh & Shannon, using Mishel's theory of uncertainty and Bandura's self‐efficacy theory.MethodsOpen‐ended, in‐depth interviews were conducted with 23 parent
Duplicate, bilateral structures of individual animals are usually symmetrical. In cases where such structures are asymmetrical, the degree of asymmetry may indicate the propensity of an individual to stray from the genetically programmed outcome during the development of the structure. Asymmetries have recently been assumed to constitute an honest signal of male quality and, as such, a cue for fem
Bradykinin receptors have been identified in human gingival fibroblasts; the primary signal transduction pathways and their dependence on calcium have been characterized. Binding data revealed a calcium-independent binding of bradykinin to the cell membrane with a receptor density of 25,000 receptors per cell and a K d

In metal cutting, tool life T combinedwith the cutting data (cutting speed, feed and depth of cut) controls largely the manufacturingcost and related co
Purpose: The purpose of this paper is to explore the current trends, implications and challenges of information systems (IS) related to omni-channel logistics. Design/methodology/approach: An exploratory survey study is conducted with 23 Swedish retail companies transforming to omni-channel logistics. The study investigates the retailers’ current situations regarding logistics IS as well as their
