Laser wakefield accelerated electron beams and betatron radiation from multijet gas targets
Laser Plasma Wakefield Accelerated (LWFA) electron beams and efficiency of betatron X-ray sources is studied using laser micromachined supersonic gas jet nozzle arrays. Separate sections of the target are used for the injection, acceleration and enhancement of electron oscillation. In this report, we present the results of LWFA and X-ray generation using dynamic gas density grid built by shock-wav
Fibroblasts direct differentiation of human breast epithelial progenitors
Background: Breast cancer arises within specific regions in the human breast referred to as the terminal duct lobular units (TDLUs). These are relatively dynamic structures characterized by sex hormone driven cyclic epithelial turnover. TDLUs consist of unique parenchymal entities embedded within a fibroblast-rich lobular stroma. Here, we established and characterized a new human breast lobular fi

Virtual collaborative design environment : Supporting seamless integration of multitouch table and immersive VR
Throughout the design of a new building it is essential that all involved stakeholders understand, communicate, participate, and collaborate with each other to acquire a high-quality result. To support these shared and creative design processes, this paper presents the design and evaluation of virtual collaborative design environment (ViCoDE) - a new collaborative design system. ViCoDE features se
Thermodynamic and kinetic design principles for amyloid-aggregation inhibitors
Understanding the mechanism of action of compounds capable of inhibiting amyloid-fibril formation is critical to the development of potential therapeutics against protein-misfolding diseases. A fundamental challenge for progress is the range of possible target species and the disparate timescales involved, since the aggregating proteins are simultaneously the reactants, products, intermediates, an

Rituximab in adult minimal change disease and focal segmental glomerulosclerosis - What is known and what is still unknown?
Primary forms of minimal change disease and focal segmental glomerulosclerosis are rare podocytopathies and clinically characterized by nephrotic syndrome. Glucocorticoids are the cornerstone of the initial immunosuppressive treatment in these two entities. Especially among adults with minimal change disease or focal segmental glomerulosclerosis, relapses, steroid dependence or resistance are comm

Evaluation of image quality for 7 iterative reconstruction algorithms in chest computed tomography imaging : A phantom study
Objectives This study aimed to evaluate the image quality of 7 iterative reconstruction (IR) algorithms in comparison to filtered back-projection (FBP) algorithm. Methods An anthropomorphic chest phantom was scanned on 4 computed tomography scanners and reconstructed with FBP and IR algorithms. Image quality of anatomical details - large/medium-sized pulmonary vessels, small pulmonary vessels, tho
Silver nanoparticles alter cell viability ex vivo and in vitro and induce proinflammatory effects in human lung fibroblasts
Silver nanoparticles (AgNPs) are commonly used in commercial and medical applications. However, AgNPs may induce toxicity, extracellular matrix (ECM) changes and inflammatory responses. Fibroblasts are key players in remodeling processes and major producers of the ECM. The aims of this study were to explore the effect of AgNPs on cell viability, both ex vivo in murine precision cut lung slices (PC
Measuring power input, power output and energy conversion efficiency in un-instrumented flying birds
Cost of flight at various speeds is a crucial determinant of flight behaviour in birds. Aerodynamic models, predicting that mechanical power (Pmech) varies with flight speed in a U-shaped manner, have been used together with an energy conversion factor (efficiency) to estimate metabolic power (Pmet). Despite few empirical studies, efficiency has been assumed constant across flight speeds at 23%. I
Factors Associated With the Outcome of a First-Line Intervention for Patients With Hip or Knee Osteoarthritis or Both : Data From the BOA Register
OBJECTIVE: This study explored the association of patients' demographics, health status, symptom severity, previous osteoarthritis (OA) care, and psychological status with the change in pain severity following a first-line intervention including education and exercise for OA provided nationwide in Swedish primary care. METHODS: This register-based cohort study included 23,309 people with knee or h
Diversity and abundance of microbial communities in uasb reactors during methane production from hydrolyzed wheat straw and lucerne
The use of straw for biofuel production is encouraged by the European Union. A previous study showed the feasibility of producing biomethane in upflow anaerobic sludge blanket (UASB) reactors using hydrolyzed, steam-pretreated wheat straw, before and after dark fermentation with Caldicellulosiruptor saccharolyticus, and lucerne. This study provides information on overall microbial community develo
Cardiovascular disease in women : Insights from magnetic resonance imaging
The presentation and identification of cardiovascular disease in women pose unique diagnostic challenges compared to men, and underrecognized conditions in this patient population may lead to clinical mismanagement. This article reviews the sex differences in cardiovascular disease, explores the diagnostic and prognostic role of cardiovascular magnetic resonance (CMR) in the spectrum of cardiovasc
Virtual reality, video screen shots and sensor data for a large drop tower ride
Large drop towers let you experience a couple of seconds of nearly free fall before stopping gracefully in magnetic brakes or bouncing a number of times on compressed air, as in the Turbo Drop tower considered in this work, where many complementary representations are used. An accelerometer taken along on the ride captured the forces experienced by the body, and a pressure sensor provided a simult
Conscious use of dreams in waking life (Nontherapy setting) for decision-making, problem-solving, attitude formation, and behavioral change
The study explored to what extent dreams have been perceived as being helpful in waking life. More specifically, for "important" waking life (conscious) decisionmaking, the solving of emotional or nonemotional (practical/technical/work-related) problems, forming/changing an attitude about something or somebody, or a conscious behavioral change of the dreamer (N = 667). On a general level, 62,1% of
Foreign ownership in Sub-Saharan Africa : Do governance structures matter?
It has been widely argued that governance structures have roles in the predominance of foreign ownership in Sub-Saharan African countries. Our paper sought to challenge this conventional wisdom by investigating the ways in which country-level governance structures influenced the predominance of foreign holdings in Sub-Saharan African countries for the period 2010-2015. The study used panel samplin
Combination of plasma amyloid beta(1-42/1-40)and glial fibrillary acidic protein strongly associates with cerebral amyloid pathology
Background: Blood-based biomarkers for Alzheimer's disease (AD) might facilitate identification of participants for clinical trials targeting amyloid beta (Abeta) accumulation, and aid in AD diagnostics. We examined the potential of plasma markers Abeta(1-42/1-40), glial fibrillary acidic protein (GFAP) and neurofilament light (NfL) to identify cerebral amyloidosis and/or disease severity. Methods
