Testing human skin and respiratory sensitizers—what is good enough?

Alternative methods for accurate in vitro assessment of skin and respiratory sensitizers are urgently needed. Sensitization is a complex biological process that cannot be evaluated accurately using single events or biomarkers, since the information content is too restricted in these measurements. On the contrary, if the tremendous information content harbored in DNA/mRNA could be mined, most compl

Comparing electricity transitions : A historical analysis of nuclear, wind and solar power in Germany and Japan

This paper contributes to understanding national variations in using low-carbon electricity sources by comparing the evolution of nuclear, wind and solar power in Germany and Japan. It develops and applies a framework for analyzing low-carbon electricity transitions based on interplay of techno-economic, political and socio-technical processes. We explain why in the 1970s–1980s, the energy paths o

Large-diameter single dowel joint : finite element modelling of a reinforced joint

Finding new efficient connectors or improving existing ones are important issues in timber construction. This research investigates an innovative large-diameter dowel-type connection by using a finite elements model calibrated with experimental results. This connection is made of a large-diameter single dowel reinforced by means of a steel plate with a vulcanised rubber layer. The steel plate shap

Effect of cutting edge radius on surface roughness and tool wear in hard turning of AISI 52100 steel

Performance of cutting tool in hard turning is significantly influenced by its microgeometry, such as edge radius. This study presents an experimental exploration to understand the effect of cutting edge radius on machining performance in terms of surface roughness and tool wear. The cutting tools (CBN) with three groups of nominal edge radius, 20, 30, and 40 μm, were used in the study. The cuttin

EVERREST prospective study : A 6-year prospective study to define the clinical and biological characteristics of pregnancies affected by severe early onset fetal growth restriction

Background: Fetal growth restriction (FGR) is a serious obstetric condition for which there is currently no treatment. The EVERREST Prospective Study has been designed to characterise the natural history of pregnancies affected by severe early onset FGR and establish a well phenotyped bio-bank. The findings will provide up-to-date information for clinicians and patients and inform the design and c

Tracer particles in two-dimensional elastic networks diffuse logarithmically slow

Several experiments on tagged molecules or particles in living systems suggest that they move anomalously slow - their mean squared displacement (MSD) increase slower than linearly with time. Leading models aimed at understanding these experiments predict that the MSD grows as a power law with a growth exponent that is smaller than unity. However, in some experiments the growth is so slow (fitted

Iconic photographs and the ebb and flow of empathic response to humanitarian disasters

The power of visual imagery is well known, enshrined in such familiar sayings as "seeing is believing" and "a picture is worth a thousand words." Iconic photos stir our emotions and transform our perspectives about life and the world in which we live. On September 2, 2015, photographs of a young Syrian child, Aylan Kurdi, lying face-down on a Turkish beach, filled the front pages of newspapers wor

Gαolf mutation allows parsing the role of cAMP-dependent and extracellular signal-regulated kinase-dependent signaling in l-3,4-dihydroxyphenylalanine-induced dyskinesia

Although l-3,4-dihydroxyphenylalanine (l-DOPA) remains the reference treatment of Parkinson's disease, its long-term beneficial effects are hindered by l-DOPA-induced dyskinesia (LID). In the dopamine (DA)-denervated striatum, l-DOPA activates DA D1 receptor (D1R) signaling, including cAMP-dependent protein kinase A (PKA) and extracellular signal-regulated kinase (ERK), two responses associated wi

The first 6 weeks of recovery after primary total hip arthroplasty with fast track : A diary study of 94 patients

Background and purpose — Fast-track protocols have been introduced worldwide to improve the recovery after total hip arthroplasty (THA). These protocols have reduced the length of hospital stay (LOS), and THA in an outpatient setting is also feasible. However, less is known regarding the first weeks after THA with fast track. We examined patients’ experiences of the first 6 weeks after hospital di

Knowledge Dump : that's not what I wiped, griped, sniped, TYPED. A Consideration of the Pedagogical Implications of Using Word Processors and their Affect on Writing

We all learned how to shape letters in different ways; with a pencil or crayon, or maybe by writing in the sand. However, basic handwriting must be understood and accomplished before graduating into the difficult skill of cursive handwriting. Professor Chris Dede relates that technologies can unobtrusively alter how we process information and express ourselves. (2012) Today, the computer is used m

Placental pulsatility index : a new, more sensitive parameter for predicting adverse outcome in pregnancies suspected of fetal growth restriction

Introduction: The pulsatility indices of the umbilical and uterine arteries are used as the surrogate measures of utero-placental perfusion. Combining the two might simplify the evaluation of total placental vascular impedance, possibly improve prediction of adverse outcomes, and help identify pregnancies with suspected fetal growth restriction that need more intense surveillance. Material and met

Projecting Lifetime Risk of Symptomatic Knee Osteoarthritis and Total Knee Replacement in Individuals Sustaining a Complete Anterior Cruciate Ligament Tear in Early Adulthood

Objective: To estimate the lifetime risk of knee osteoarthritis (OA) and total knee replacement (TKR) in persons sustaining anterior cruciate ligament (ACL) tear by age 25 years. Methods: We used the Osteoarthritis Policy Model to project the cumulative incidence of symptomatic knee OA requiring TKR in varying situations: no prevalent or incident injury; isolated ACL tear, surgically treated; isol

Challenges in the industrial implementation of generative design systems : An exploratory study

The aim of this paper is to investigate the challenges associated with the industrial implementation of generative design systems. Though many studies have been aimed at validating either the technical feasibility or the usefulness of generative design systems, there is, however, a lack of research on the practical implementation and adaptation in industry. To that end, this paper presents two cas

Efficacy versus effectiveness of clinical genetic testing criteria for BRCA1 and BRCA2 hereditary mutations in incident breast cancer

Increasing evidence supports the benefit of identifying BRCA1 and BRCA2 germline mutations in early breast cancer. Selection of patients for genetic testing is based on defined criteria taking individual and family history related factors into account. It is important to make a distinction between efficacy and effectiveness of BRCA testing criteria. Efficacy can be defined as the performance under

Penicillin-susceptible Staphylococcus aureus : susceptibility testing, resistance rates and outcome of infection

Background: Staphylococcus aureus (SA) is an important human pathogen that causes both superficial and invasive infections. Penicillin is now rarely used in the treatment of SA infections due to widespread resistance and a concern about the accuracy of existing methods for penicillin susceptibility testing. The aims of the present study were to determine the frequency of penicillin-susceptible SA
