Positron emission tomography (PET) is a form of nuclear imaging, which quantitatively assesses the metabolic activity through the uptake of radioactive tracers. 18 F-fluoride is a positron-emitting isotope with high affinity for bone. Despite its potential as a non-invasive measure of bone metabolism, quantitative 18 F-fluoride PET has only been used sparsely in orthopaedic applications. It has
Syftet med denna studie är att undersöka och jämföra hur undervisning i digitala miljöer konstrueras, dels i reflekterande texter skrivna av universitetslärare som deltog i en högskolepedagogisk kurs 2017–2018, dels i styrdokument om e-lärande från svenska lärosäten. Resultatet visar att lärarnas och styrdokumentens diskurser emellanåt står i kontrast till varandra. Medan de senare såväl explicit
Bulk properties of cortical bone have been well characterized experimentally, and potent toughening mechanisms, e.g., crack deflections, have been identified at the microscale. However, it is currently difficult to experimentally measure local damage properties and isolate their effect on the tissue fracture resistance. Instead, computer models can be used to analyze the impact of local characteri
Multiplex separation of mixed cell samples is required in a variety of clinical and research applications. Herein, we present an acoustic microchip with multiple outlets and integrated pre-alignment channel to enable high performance and label-free separation of three different cell or particle fractions simultaneously at high sample throughput. By implementing a new cooling system for rigorous t
Background: A fragrance mix consisting of eight separate fragrance ingredients (fragrance mix I [FM I]) is present in most baseline patch test series. Patch testing with the TRUE Test technique is considered to detect less contact allergy to FM I than testing with the Finn Chamber technique. Objective: To investigate the possible significance of batch and patch test method in establishing contact
Anthropogenic land cover change (ALCC) is the most important transformation of the Earth system that occurred in the preindustrial Holocene, with implications for carbon, water and sediment cycles, biodiversity and the provision of ecosystem services and regional and global climate. For example, anthropogenic deforestation in preindustrial Eurasia may have led to feedbacks to the climate system:
Introduction: Community Case Management (CCM) aims to improve health outcomes among children under five with malaria, diarrhea, and pneumonia, but its effectiveness in Malawi is limited by inconsistent standards of delivery characteristic of paper-based interventions. This may lead to negative impacts on child health outcomes and inefficient use of health system resources. This study evaluated the
Background: Endoscopic submucosal dissection (ESD) is an advanced method allowing en bloc resection of large and complex lesions in colon and rectum. Herein, the European experience of colorectal ESD was systematically reviewed in the medical literature to determine the clinical efficacy and safety of colorectal ESD in Europe. Material and methods: A systematic search of PubMed for full-text studi
The radiological consequences of a nuclear power plant (NPP) accident, resulting in the release of radionuclides to the environment, will depend largely on the mitigating actions instigated shortly after the accident. It is therefore important to make predictions of the radiation dose to the affected population, from external as well as internal exposure, soon after an accident, despite the fact
Triose-phosphate isomerase (TIM) catalyses the interconversion of dihydroxyacetone phosphate and glyceraldehyde 3-phosphate. Two catalytic mechanisms have been proposed based on two reaction-intermediate analogues, 2-phosphoglycolate (2PG) and phosphoglycolohydroxamate (PGH), that have been used as mimics of the cis-enediol(ate) intermediate in several studies of TIM. The protonation states that a
Throughout time, communities have adapted to changes in their environment and, in doing so, have addressed risksthat threaten the things they value. The need to adapt is considered more urgent now than ever, notably given thecurrent focus on climate risk. Typically, adaptation is presented as a solution to reduce such risks. This is particularlythe case for Landlocked Developing Countries and Smal
BackgroundProduction of ethanol and biogas from acetic acid-impregnated steam-pretreated wheat straw was investigated. The solid fraction after pretreatment was used at high solids concentrations to generate ethanol by simultaneous saccharification and fermentation (SSF). The residual streams were evaluated with regard to biogas production. The experimental results were used to perform a techno-ec
On-site cellulase enzyme fermentation in a softwood-to-ethanol process, based on S -catalysed steam pretreatment followed by simultaneous saccharification and fermentation, was investigated from a techno-economic aspect using Aspen Plus and Aspen Icarus Process Evaluator softwares. The effect of varying the carbon source of enzyme fermentation, at constant protein and mycelium yields, was monitore
Purpose: Undifferentiated uterine sarcomas (UUS) are rare, extremely deadly, sarcomas with no effective treatment. The goal of this study was to identify novel intrinsic molecular UUS subtypes using integrated clinical, histopathologic, and molecular evaluation of a large, fully annotated, patient cohort. Experimental Design: Fifty cases of UUS with full clinicopathologic annotation were analyzed
Background: Existing evidence for the prospective association of vitamin D status with type 2 diabetes (T2D) is focused almost exclusively on circulating total 25-hydroxyvitamin D [25(OH)D] without distinction between its subtypes: Nonepimeric and epimeric 25(OH)D 3 stereoisomers, and 25(OH)D 2 , the minor component of 25(OH)D. We aimed to investigate the prospective associations of circulating
The top quark mass is measured using a template method in the tt¯ → lepton + jets channel (lepton is e or μ) using ATLAS data recorded in 2012 at the LHC. The data were taken at a proton–proton centre-of-mass energy of s=8 TeV and correspond to an integrated luminosity of 20.2 fb - 1 . The tt¯ → lepton + jets channel is characterized by the presence of a charged lepton, a neutrino and four jets, t
