Creatinine-based equations to estimate glomerular filtration rate (GFR) are increasingly used in radiological practice and in studies on contrast medium-induced acute kidney injury (CIAKI). Their use is recommended in guidelines and contrast medium textbooks to identify patients at risk of CIAKI or nephrogenic systemic fibrosis. There is also an increased interest in cystatin C-based equations. Ad
BACKGROUND: Electrophoresis of serum samples allows detection of monoclonal gammopathies indicative of multiple myeloma, Waldenstrom macroglobulinemia, monoclonal gammopathy of undetermined significance, and amyloidosis. Present methods of high-resolution agarose gel electrophoresis (HRAGE) and immunofixation electrophoresis (IFE) are manual and labor-intensive. Capillary zone electrophoresis (CZE
Objectives The aim of the present study was to test whether construction workers, who are known to have a relatively higher risk of cardiovascular disease (CVD), had higher concentrations of cortisol in saliva and a lower relative variability when compared with white-collar workers. Methods Data from two groups of male construction workers with physically demanding job assignments, with either reg
Hand prostheses that are currently available on the market are used by amputees to only a limited extent, partly because of lack of sensory feedback from the artificial hand. We report a pilot study that showed how amputees can experience a robot-like advanced hand prosthesis as part of their own body. We induced a perceptual illusion by which touch applied to the stump of the arm was experienced
Haemophilia care has undergone substantial improvements during the past 40-50 years. Early clotting factor concentrates were not sufficiently refined to enable self-administered treatment at home until the 1970s. Unfortunately, these advances led to transmission of viral diseases including HIV and hepatitis, resulting in an increased burden of morbidity and mortality, especially during the 1980s.
Popular Abstract in Swedish En spännande utmaning för forskare inom både akademin och industrin är att utveckla industriella processer som mer effektivt använder både befintliga som alternativa råvaror för produktion av viktiga kemiska intermediat. Sådana intermediat används i sin tur som råvara för att framställa funktionella och idag ovärderliga material såsom plaster, fibrer, gummin, färger, ytSince the metal oxide catalysts used in many chemical processes show very high selectivity for the products aimed at, both today and in the future, they play a key role in the environmentally and economically sustainable production of chemical intermediates. Two processes of this sort have been studied in the thesis: the ammoxidation of propane and propene over a Mo-V-Nb-Te-oxide catalyst and the
Objective. The volume of colonoscopies performed is increasing and differences in colonoscopy practice over time and between centres have been reported. Examination of current practice is important for benchmarking quality. The objective of this study was to examine variations in colonoscopy practice in endoscopy centres internationally. Material and methods. This observational study prospectively
This survey overviews the potential use of cryptographic primitives in the fifth-generation mobile communications system (aka 5G) and beyond. It discusses the new security challenges that come with 5G and presents the upcoming security architecture. It shows the use of current cryptographic algorithms and discusses new algorithms or modifications of existing ones, that can be relevant. It also dis
Birds possess a magnetic sense and rely on the Earth's magnetic field for orientation during migration. However, the geomagnetic field can be altered by solar activity at relative unpredictable intervals. How birds cope with the temporal geomagnetic variations caused by solar storms during migration is still unclear. We addressed this question by reproducing the effect of a solar storm on the geom
Walking difficulties are common in neurological and other disorders, as well as among the elderly. There is a need for reliable and valid instruments for measuring walking difficulties in everyday life since existing gait tests are clinician rated and focus on situation specific capacity. The Walk-12G was adapted from the 12-item multiple sclerosis walking scale as a generic patient-reported ratin
We describe a new method for analysis of change in glaucomatous visual fields with the object to differentiate between changes caused by glaucoma from those caused by cataract, New pattern deviation change probability maps were developed from a prospectively collected glaucoma material and designed to be sensitive to changes in localized field loss, but to be unaffected by media-induced perimetric
Transitions towards sustainability are urgently needed to address the interconnected challenges of economic development, ecological integrity, and social justice, from local to global scales. Around the world, collaborative science-society initiatives are forming to conduct experiments in support of sustainability transitions. Such experiments, if carefully designed, provide significant learning o
Cities have long been recognized as potential hubs of knowledge, social and cultural diversity, jobs, education, public services, and infrastructure. Alongside these opportunities, however, cities also face a changing climate, reduced availability of raw materials and natural resources, and dwindling physical space for the built environment. These challenges are accompanied by increasing dispariti
Membrane fouling and its control is one of the most critical parameters in the application of membrane processes. The degree of fouling depends on the application and on industrial scale, fouling is often observed as reduction in plant capacity over time. One approach to reduce fouling for the pressure driven processes microfiltration and ultrafiltration is to use hydrophilic membranes. This paper
The study of growth in African economies during the 20th Century is hampered by the lack of historical GDP estimates. There has been some backward projections, and country case studies, but despite the available data historical national accounts has not yet been assembled. This paper provides GDP estimates for some former British colonies between 1900 – 1950. The estimates indicate faster growth a
This article contributes to the debates surrounding "New African Economic History" by exploring the feasibility of constructing a time series of economic growth in Nigeria spanning the whole twentieth century. Currently most datasets for African economies only go back to 1960. The sources for their creation exist, but these valuable colonial data remain underutilized. This is an exploratory paper
Glass is largely used in architectural and engineering applications (i.e., buildings and vehicles) as a structural material, especially in the form of laminated glass (LG) sections. To achieve adequate and controlled safety levels in these applications, the well-known temperature-dependent behavior of viscoelastic interlayers for LG sections should be properly accounted for during the design proce
This paper develops the models for the structural performance of the loading and probabilistic characterization for the fatigue and the serviceability limit states for the support structure of offshore wind energy converters. These models and a sensitivity study are part of a risk based assessment and monitoring framework and will be applied for establishing the "as designed and constructed" relia
