Quantification of chondroitin sulfates and hyaluronan in synovial fluid using high performance liquid chromatography

Purpose: Extracellular proteins such as aggrecan may be primed with specific glycan-patterns which result in their degradation, and hence may play a role in the pathogenesis of osteoarthritis (OA). To be able to use glycans as molecular biomarkers, the method of analysis of these molecules needs to be validated. The primary aim of this study was to validate quantitative high performance liquid chr

Taxonomy supporting design strategies for reuse of building parts in timber-based construction

PurposeThe reuse of timber building parts, when designing new buildings, has become a topic of increasing discussion as a proposed circular solution in support of sustainable development goals. Designers face the difficulty of identifying and applying different design strategies for reuse due to multiple definitions, which are used interchangeably. The purpose of this study is to propose a taxonom

FDG-PET/CT for lymph node staging prior to radical cystectomy

Background: 18F-Fluorodeoxyglucose positron emission combined with computed tomography (FDG-PET/CT) has been proposed to improve preoperative staging in patients with bladder cancer subjected to radical cystectomy (RC). Objective: Our aim was to assess the accuracy of FDG-PET/CT for lymph node staging ascertained at the multidisciplinary tumour board compared to lymph node status in the surgical l

Assessment of projection interpolation to compensate for the increased radiation dose in DBTMI

The combination of digital breast tomosynthesis (DBT) with other imaging modalities has been investigated in order to improve the detection and diagnosis of breast cancer. Mechanical Imaging (MI) measures the stress over the surface of the compressed breast, using a pressure sensor, during radiographic examination and its response has shown a correlation with the presence of malignant lesions. Thu

A time adaptive multirate Dirichlet–Neumann waveform relaxation method for heterogeneous coupled heat equations

We consider partitioned time integration for heterogeneous coupled heat equations. First and second order multirate, as well as time-adaptive Dirichlet-Neumann Waveform relaxation (DNWR) methods are derived. In 1D and for implicit Euler time integration, we analytically determine optimal relaxation parameters for the fully discrete scheme. We test the robustness of the relaxation parameters on the

Chloride-Based Additive Engineering for Efficient and Stable Wide-Bandgap Perovskite Solar Cells

Metal halide perovskite based tandem solar cells are promising to achieve power conversion efficiency beyond the theoretical limit of their single-junction counterparts. However, overcoming the significant open-circuit voltage deficit present in wide-bandgap perovskite solar cells remains a major hurdle for realizing efficient and stable perovskite tandem cells. Here, a holistic approach to overco

Old meets new : vNOTES retroperitoneal promontory fixation in conjunction with the uterus preserving Manchester procedure✰,✰✰

Introduction and Hypothesis: The Manchester procedure is a classic native tissue prolapse technique with low recurrence and low complication rate. vNOTES (vaginal natural orifice transluminal endoscopic surgery) is a vaginal approach to enter the intra or retroperitoneal space, with the guidance of endoscopic visualization. Different studies have shown women to prefer uterus-preserving correction

Connecting organizational context to environmental sustainability initiatives and industrial symbiosis : Empirical results and case analysis

Industrial symbiosis can move us closer to a circular economy and enable efficient and sustainable use of resources. Its potential has however been far from realized, and to increase our understanding of why that is, we investigate drivers, barriers, and outcomes associated with both broadly defined environmental sustainability initiatives and industrial symbiosis from an organizational context pe

Striking stability of a mixed-valence thallium(III)-thallium(I) complex in some solvents

At the dissolution of solid anhydrous thallium(III) trifluoromethanesulfonate, Tl(CF3SO3)3, or thallium(III) trifluoroacetate, Tl(CF3COO)3, in dimethylsulfoxide (dmso) or N,N,N’,N’-tetramethylurea (tmu), intensely red-colored complexes are formed. This red thallium complex is stable for years in dmso, while it is reduced fairly rapidly to thallium(I) in tmu with a half-life time of an hour. At the

Allergic contact dermatitis from octylisothiazolinone

BACKGROUND: Octylisothiazolinone is a biocide that has been reported as a moderate, but rare contact allergen.OBJECTIVES: To investigate the occurrence of octylisothiazolinone contact allergy and allergic contact dermatitis diagnosed and registered in the Allergen Bank at Odense University Hospital during the past 20 years. Octylisothiazolinone has been used for targeted testing only.METHOD: All o

Risk Factors for Long-Term Contracture Recurrence after Collagenase Injection for Dupuytren Disease : A Prospective Cohort Study

In Dupuytren disease, little is known about the long-term outcomes of collagenase injection or risk factors for contracture recurrence. In this prospective study, 159 patients (242 fingers) with Dupuytren disease and active extension deficit (AED) ≥20° in a metacarpophalangeal (MCP) or proximal interphalangeal (PIP) joint were treated with collagenase injection during a 14-month period. At 5 years

Occupational contact dermatitis in painters : an analysis of patch test data from the Danish Contact Dermatitis Group

BACKGROUND: Painters are among the occupational groups that most commonly experience occupational contact dermatitis, but few investigations exist concerning this occupation.OBJECTIVES: To characterize painters with contact dermatitis and identify the most common allergens associated with the occupation. Materials and methods. All patch test results of 219 painters and 1095 matched controls regist

The influence of acetylsalicylic acid and alcohol on absorption kinetics of hen´s egg white in a human passive cutaneous anaphylaxis model

Background: Despite the well-known fact that acetylsalicylic acid (ASA) can induce anaphylaxis in patients susceptible to wheat-dependent exercise-induced anaphylaxis, few studies have sought to investigate the effects of cofactors on type-1 food allergy and none with ASA and hen’s egg and hen’s egg and alcohol combined. Methods and results: We applied the experimental model of ‘passive cutaneous
