Ceramic biomaterials are promising alternatives to bone autografts. However, limited bioactivity affects their performance. Therefore, bioactive molecules and cells are often added to enhance their performance. Exosomes have emerged as cell-secreted vesicles, delivering proteins, lipids, and nucleic acids in a paracrine/endocrine fashion. We studied two complementary aspects required for exosome a
Background: Current clinical decision rules to exclude deep vein thrombosis (DVT) are underused partly because of their complexity. A simplified rule that can be easily applied would be more appealing to use in clinical practice. Methods: We used individual patient data from prospective diagnostic studies of patients suspected of DVT to develop a new clinical decision rule. The primary outcome was
In this article, we consider the properties of the Pesaran CD test for cross-section correlation when applied to residuals obtained from panel data models with many estimated parameters. We show that the presence of period-specific parameters leads the CD test statistic to diverge as the time dimension of the sample grows. This result holds even if cross-section dependence is correctly accounted f
Objective: We studied cytokines in gingival crevicular fluid (GCF) in a cross-sectional population-based cohort of rheumatoid arthritis (RA) patients ≥61 years of age with and without a diagnosis of periodontitis. Background data: Earlier studies on cytokines in GCF in RA patients have not given clear results. Methods: In a population-based cross-sectional study of patients ≥61 years of age, 233 R
Background: Patients with inflammatory bowel disease (IBD) have an increased risk of compromised bone mineral density (BMD) and body composition. There are limited data on the physical exercise (PE) habits of patients with childhood-onset IBD and on the associations between PE and BMD and body composition. Patients and methods: In total, 72 young adults with childhood-onset IBD and 1341 normative
Myanmar is in a dangerous and uncertain moment following the military coup on 1 February 2021. The articles in this Special Forum provide timely contextual analysis. Written before the coup, the articles delve into the politics of agrarian transformation in the context of (what was then) an ongoing (but fragile) opening up of political space. This introduction outlines three themes that connect th
Background. Recently, the Occupational Balance Questionnaire developed in Sweden was translated into Norwegian. No studies to date have examined the measurement properties of the Norwegian version of this questionnaire. Aim. The study is aimed at examining the psychometric properties of the Norwegian version of the Occupational Balance Questionnaire, the OBQ11-N. Methods. Along with sociodemograph
Monitoring pollution of PM2.5 on walkable roads is important for resident health in high-density cities. Due to the spatiotemporal resolution limitations of Aerosol Optical Depth (AOD) observation, fixed-point monitoring, or traditional mobile measurement instruments, the microscale PM2.5 distribution in the walking environment cannot be fully estimated at the fine scale. In this study, by the int
Objective: The effectiveness of GBR procedures for the reconstruction of periodontal defects has been well documented. The objective of this investigation was to evaluate the degradation kinetics and biocompatibility of two resorbable collagen membranes in conjunction with a bovine xenograft material. Materials and Methods: Lower premolars and first molars were extracted from 18 male Yucatan minip
We present a methodological workflow using two open science tools that we developed. The first, FBAdLibrian, collects images from the Facebook Ad Library. The second, Pykognition, simplifies facial and emotion detection in images using computer vision. We provide a methodological workflow for using these tools and apply them to a case study of the 2020 US primary elections. We find that unique ima
There is great potential to apply energy recovery from municipal wastewater treatment plants (WWTP) to achieve better energy efficiency and greenhouse gas emissions abatement. However, in most of the wastewater treatment plants that produce biogas through sludge digestion, there is no thermal energy recovery or electricity generation, and the biogas is flared and wasted, particularly in developing
Chronic respiratory diseases are often characterized by impaired epithelial function and remodeling. Mast cells (MCs) are known to home into the epithelium in respiratory diseases, but the MC-epithelial interactions remain less understood. Therefore, this study aimed to investigate the effect of MC proteases on bronchial epithelial morphology and function. Bronchial epithelial cells were stimulate
Recent research has foregrounded the importance of student engagement with feedback on writing (Quinton & Smallbone, 2010; Zhang & Hyland, 2018; Handley, Price, & Millar, 2011). At the same time, there is a small but growing body of scholarship exploring the role that feedback plays in developing discipline-specific competencies in student writers in an L2 context (Hyland, 2013). The p
In this paper we investigate the specific mechanisms of British financial influence in the Cape Colony during the diamond mining boom of the late nineteenth century. We do so by offering a detailed exposition of the uneasy marriage between the colonial state and private business sector in the context of the economics and dynamics of extractivism in the periphery. This allows us to encapsulate the
This work aims to unravel the impact of disubstitution patterns on the physical properties and processing characteristics of indole-based aromatic polyesters. A series of hydroxyl-carboxylate (AB-type) monomers with 1,5-disubstituted indole and 3-6 methylene units was conveniently synthesized and used in bulk polycondensation to yield the corresponding polyesters with decent molecular weight. Thes
BACKGROUND: This aggregated population study investigated the impact of the seemingly quasi-randomly assigned school winter holiday in weeks 6-10 (February to early March) on excess mortality in 219 European regions (11 countries) during the COVID-19 pandemic in the spring 2020. A secondary aim was to evaluate the impact of government responses to the early inflow of infected cases. METHODS: Data
CONTEXT/OBJECTIVE: The aim of this study was to examine the effect of statins and other lipid-lowering agents on the development of Graves orbitopathy (GO) in patients with newly diagnosed Graves disease (GD). METHODS: Our sample included the full adult population of individuals living in Sweden with newly diagnosed GD between 2005 and 2018 (n = 34 894). We compared the GO incidence in statin user
