OBJECTIVE: To investigate the relationship between cognitive reserve (CR) and clinical progression across the Alzheimer disease (AD) spectrum. METHODS: We selected 839 β-amyloid (Aβ)-positive participants with normal cognition (NC, n = 175), mild cognitive impairment (MCI, n = 437), or AD dementia (n = 227) from the Alzheimer's Disease Neuroimaging Initiative (ADNI). CR was quantified using standa
The spatial distribution of organic soil nitrogen (N) in alpine tundra was studied along a natural environmental gradient, covering five plant communities, at the Latnjajaure Field Station, northern Swedish Lapland. The five communities (mesic meadow, meadow snowbed, dry heath, mesic heath, and heath snowbed) are the dominant types in this region and are differentiated by soil pH. Net N mineraliza
It must be remembered that clinically important haemostasis occurs in vivo and not in a tube, and that variables such as the number of bleeding events and bleeding volume are more robust measures of bleeding risk than the results of analyses. In this narrative review, we highlight trauma, surgery, and mild induced hypothermia as three clinically important situations in which the effects of hypothe
Brain centers possessing a suite of neuroanatomical characters that define mushroom bodies of dicondylic insects have been identified in mantis shrimps, which are basal malacostracan crustaceans. Recent studies of the caridean shrimp Lebbeus groenlandicus further demonstrate the existence of mushroom bodies in Malacostraca. Nevertheless, received opinion promulgates the hypothesis that domed cente
Huntingtons sjukdom (HS) är en ärftlig fortskridande neurodegenerativ sjukdomsom orsakas av en förlängd CAG sekvens i huntingtin (HTT) genen, vilket leder till motoriska och kognitiva symptom samt personlighetsförändringar. Eftersom den muterade genen och proteinet den kodar för finns uttryckt i kroppens alla celler resulterar det i att även organ utanför hjärnan påverkas. En förhöjd ämnesomsättniHuntington´s disease (HD) is a fatal inherited neurodegenerative disorder caused by a CAG triplet repeat expansion in the huntingtin (HTT) gene and characterized by cognitive and motoric dysfunctions as well as psychiatric problems. Accumulating evidence, however, suggests altered energy metabolism and a hyper-catabolic state as key features of HD pathology. In clinical HD, body weight has been sh
Members of the New Kinase Family 3 (NKF3), PEAK1/SgK269 and Pragmin/SgK223 pseudokinases, have emerged as important regulators of cell motility and cancer progression. Here, we demonstrate that C19orf35 (PEAK3), a newly identified member of the NKF3 family, is a kinase-like protein evolutionarily conserved across mammals and birds and a regulator of cell motility. In contrast to its family members
Undifferentiated pleomorphic sarcoma (UPS) is a highly aggressive soft tissue tumor. A subset of UPS is characterized by a CITED2–PRDM10 or a MED12–PRDM10 gene fusion. Preliminary data suggest that these so-called PRDM10-rearranged tumors (PRT) are clinically more indolent than classical high-grade UPS, and hence important to recognize. Here, we assessed the spectrum of accompanying mutations and
A molecular motor potentially performing a continuous unidirectional rotation is studied by a multidisciplinary approach including organic synthesis, transient spectroscopy and excited state trajectory calculations. A stereogenic center was introduced in the N-alkylated indanylidene-pyrroline Schiff base framework of a previously investigated light-driven molecular switch in order to achieve the u
A non-commercial knowledge base providing assessments of fetal risks of medicinal drugs is a useful tool in the everyday work of midwives. The information is freely available on the internet, and according to a questionnaire study, nearly 95% of the midwives are familiar with the database, 30% use the information weekly, and 80% express that it affects their medical decisions. A vast majority of t
The p53 tumor suppressor restricts tumorigenesis through the transcriptional activation of target genes involved in cell-cycle arrest and apoptosis. Here, we identify Prl-3 (phosphatase of regenerating liver-3) as a p53-inducible gene. Whereas previous studies implicated Prl-3 in metastasis because of its overexpression in metastatic human colorectal cancer and its ability to promote invasiveness
OBJECTIVES: Infections with extended spectrum beta-lactamase (ESBL) producing Enterobacteriaceae (EPE) are a major healthcare concern. Our goal was to investigate whether a probiotic mixture could be used for eradication therapy in patients with prolonged intestinal EPE carriage.METHODS: We performed a randomized, placebo-controlled single blinded clinical superiority trial in the south of Sweden
This paper attempts to assemble a conceptual framework for understanding to what extent an energy technology is simply a way of putting nature to work, and to what extent it is a way of putting other segments of global society to work. The turn to fossil energy reversed the relation between energy and space, as fossil fuels henceforth propelled new transport technologies that provided access to in
In this contribution a practical and rational decision-making approach is presented to be applied for common bridges typically managed by public authorities. The authors have developed a model with the intention to be applicable for practical cases for common bridges in the daily work of bride operators responsible for a large number of assets, yet still maintain the principles of more generic fra
Purpose: The purpose of this study is to enhance the thermal performance in the labyrinth channel by different ribs shape. The labyrinth channel is a relatively new cooling structure to decrease the temperature near the trailing region of gas turbine. Design/methodology/approach: Based on the geometric similarity, a simplified geometric model is used. The k − ω turbulence model is used to close th
As urban systems continue to grow worldwide, urban peripheries increase in number and typologies, which makes their planning a challenge for sustainable development. The aim of this article is to explore approaches and challenges related to the application of sustainable planning to urban peripheries. We reviewed the content of 102 papers related to sustainable planning in urban peripheries by app
1-(Benzothiazol-2-yl)-1-(4-chlorophenyl)ethanol (1) was identified as a positive allosteric modulator (PAM) of the CaSR in a functional cell-based assay. This compound belongs to a class of compounds that is structurally distinct from other known positive allosteric modulators, for example, the phenylalkylamines cinacalcet, a modified analog (13) potently suppressed parathyroid hormone (PTH) relea
