A key challenge in the field is to confer biorecognition units to UCNPs so that they can be used to probe specific targets in biological systems. While various agents have been combined with UCNPs to meet such a challenge, most studies are limited to small molecules, while biomolecules such as metalloproteins that possess much higher affinity and selectivity for metal ions have not been explored. Herein we demonstrate that fusion of zwitterion-coated UCNPs with azurin, a member of a family of redox-active copper proteins called cupredoxins that play important roles in diverse biological functions, can serve as an ideal platform for the label-free upconversion luminescence sensing of Cu2+ with a ratiometric response. The selectively binding of apo-azurin with Cu2+ induce a significant absorbance at about 625 nm, and hence decreases the red emission of the UCNPs. In contrast, the green emission of the UCNPs remains constant and acts as an internal standard reference for the ratiometric sensing of Cu2+. https://www.selleckchem.com/products/alpha-naphthoflavone.html This approach opens a new window for the development of assays for biosensing based on a combination of specific metalloproteins with UCNPs.Background Nightshift work is a plausible risk factor for hematologic cancer, but epidemiological evidence remains sparse, especially for individual subtypes. We prospectively examined the association of rotating nightshift work with hematopoietic cancer risk. Methods This cohort study included US women from the Nurses' Health Study (NHS n = 76 846, 1988-2012) and Nurses' Health Study II (NHSII n = 113 087, 1989-2013). Rotating nightshift work duration was assessed at baseline (both cohorts) and cumulatively updated (NHSII). Cox regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for overall hematopoietic cancer and specific histologic subtypes. All statistical tests were two-sided. Results We documented 1405 (NHS) and 505 (NHSII) incident hematopoietic cancer cases during follow-up. In NHS, compared with women who never worked rotating nightshifts, longer rotating nightshift work duration was associated with an increased risk of overall hematopoietic cancer (HR1-14y = 0.93,he Author(s) 2019. Published by Oxford University Press.in English, French L’attitude environnementale (AE) a été connu d’etre construit multidimensionnel et complexe avec des preuves empiriques minimales dans les pays en voie de développement. Dans l’etude actuelle, les propriétés psychométriques d’une échelle d’évaluation environnementale ont été évaluées de manière empirique à l’aide de données provenant d’une étude menée au niveau communautaire au Nigeria. Différentes mesures d’évaluation environnementale ont été regroupées dans une seule échelle d’évaluation et administrées à 1 858 personnes. La moyenne (type écart) et les proportions ont été utilisées pour décrire la distribution des données continues et discrètes, respectivement. La fiabilité de l’échelle a été évaluée à l’aide du coefficient alpha de Cronbach. Différents modèles hypothétiques de l’AE ont été évalués à l’aide d’une analyse factorielle exploratoire (AFE) et d’une analyse factorielle confirmatoire (AFC). Les données ont été analysées avec IBM SPSS version 20 et AMOS version 21 à un niveau significatif de 5%. Le score moyen global et le coefficient alpha de la mesure de l’EA combinée étaient respectivement de 381,7 (49,0) et 0,928. Une structure à 3 facteurs représentant une variance cumulée de 36% de l’élément d’échelle a été extraite dans un EFA. Un modèle à 3 facteurs non orthogonal constituait une amélioration significative par rapport au modèle original à 5 facteurs sans corrélation [χ2 (1344) = 29216,33, p less then 0,001; CAIC = 9816.870]. La conceptualisation de l’AE en tant que structure à 3 facteurs non orthogonale offre un meilleur ajustement aux données actuelles. La structure à 3 facteurs est conseillée au Nigeria et dans des contextes similaires.Purpose Many East Asian Americans (EAAs) (populations originating from China, Korea, Japan, and Taiwan) with type 2 diabetes mellitus (T2DM) experience unique challenges in managing their disease, including language barriers and traditional cultural beliefs, particularly among first-generation immigrants.. The purpose of this mixed-methods systematic review was to examine cultural perspectives of EAAs that influence dietary self-management of T2DM and identify education interventions and their approaches to enhance EAAs' dietary self-management of diabetes. Methods A mixed-methods systematic review was conducted to examine EAAs' perspectives from qualitative studies and to identify education interventions and their approaches from quantitative studies. A literature search was conducted using PubMed/MEDLINE, SCOPUS, CINAHL, and Web of Science from 1995 to 2018. Sixteen studies (10 qualitative and 6 quantitative) met criteria for analysis. Thematic synthesis of qualitative data was conducted using a line-by-linT2DM and tailoring interventions to meet the needs of EAAs are essential in effort to address the growing epidemic and improve patient outcomes. © Tony Li-Geng et al. 2020; Published by Mary Ann Liebert, Inc.Aortic valve stenosis remains the most frequent structural heart disease, especially in the elderly. During the last decade, we noticed an important consideration and a huge number of publications related to the medical and surgical treatment of this disease. However, the molecular aspect of this degenerative issue has also been more widely studied recently. As evidenced in oncologic but also cardiac research fields, the emergence of microRNAs in the molecular screening and follow-up makes them potential biomarkers in the future, for the diagnosis, follow-up and treatment of aortic stenosis. Herein, we present a review on the implication of microRNAs in the aortic valve disease management. After listing and describing the main miRNAs of interest in the field, we provide an outline to develop miRNAs as innovative biomarkers and innovative therapeutic strategies, and describe a groundbreaking pre-clinical study using inhibitors of miR-34a in a pre-clinical model of aortic valve stenosis. © 2020 Production and hosting by Elsevier B.
