Combining Scattering Experiments and Colloid Theory to Characterize Charge Effects in Concentrated Antibody Solutions

Charges and their contribution to protein-protein interactions are essential for the key structural and dynamic properties of monoclonal antibody (mAb) solutions. In fact, they influence the apparent molecular weight, the static structure factor, the collective diffusion coefficient, or the relative viscosity, and their concentration dependence. Further, charges play an important role in the collo

Thyroid disease in ANCA-associated vasculitis : a clinical and epidemiological study

Objectives To describe clinical and laboratory characteristics and outcomes in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and thyroid disease (TD). We also aimed to calculate incidence and identify predictors of TD in two large cohorts of patients with AAV. Methods The study comprised 644 patients with AAV in a population-based cohort from southern Sweden

Infective native aneurysms of the infrapopliteal arteries – A systematic literature review and report of two cases

Infective native aneurysms (INA) of the infrapopliteal arteries are rare and have previously been poorly described. This systematic review aims to provide an overview of the literature of this entity. Furthermore, two case reports of our own clinical experience are presented. PubMed, ScienceDirect, Cochrane, Ovid Embase, Ovid MEDLINE, and Web of Science were searched for articles on INAs of the in

Characterization of Trapping Effects Related to Carbon Doping Level in AlGaN Back-Barriers for AlGaN/GaN HEMTs

The impact of different carbon concentrations in the Al 0.06 Ga 0.94 N graded back-barrier and GaN buffer of high electron mobility transistors (HEMTs) is investigated. Four epi-wafers with different carbon concentrations, ranging from 1 × 10 17 to 5 × 10 17 cm −3 , were grown by metal organic chemical vapor deposition (MOCVD). HEMTs with 100 and 200 nm gate lengths were fabricated and characteriz

Rational molecular design of partly fluorinated fuel cell membranes with high proton conductivity under low-humidity conditions

Research on proton exchange membranes (PEMs) is closely tied to the development of PEM fuel cells, and the need to overcome the shortcomings of perfluorosulfonic acid PEMs. One of the key challenges is to devise efficient molecular designs towards PEMs with sufficient durability and proton conductivity under reduced humidity. Here, we report on a series of partly fluorinated PEMs based on high-mol

Examining labelling guidelines for AI-based software as a medical device : A review and analysis of dermatology mobile applications in Australia

In recent years, there has been a surge in the development of AI-based Software as a Medical Device (SaMD), particularly in visual specialties such as dermatology. In Australia, the Therapeutic Goods Administration (TGA) regulates AI-based SaMD to ensure its safe use. Proper labelling of these devices is crucial to ensure that healthcare professionals and the general public understand how to use t

Weyl spin-momentum locking in a chiral topological semimetal

Spin-orbit coupling in noncentrosymmetric crystals leads to spin-momentum locking – a directional relationship between an electron’s spin angular momentum and its linear momentum. Isotropic orthogonal Rashba spin-momentum locking has been studied for decades, while its counterpart, isotropic parallel Weyl spin-momentum locking has remained elusive in experiments. Theory predicts that Weyl spin-mom

Alternative drying technologies for biologics

This doctoral thesis aims to investigate and compare conventional drying technologies (freeze-drying and spray drying) to alternative drying technologies for biologics. Vacuum foam-drying was identified as an alternative drying technology for biologics. Vacuum foam-drying is a drying technique that involves solvent removal by evaporation, at lowered pressure and ambient temperatures. Thus, vacuum

Psychometric properties of the EQ-5D-5L in patients with knee or hip osteoarthritis : confirmatory factor analysis and item response theory

Purpose (the aim of the study): There is limited evidence on psychometric properties of EQ-5D-5L among people with osteoarthritis (OA) undertaking non-surgical treatment. The aim of the current study was to evaluate the psychometric properties of the EQ-5D-5L among individuals with knee or hip OA participating in a digitally delivered education and exercise therapy.Methods: Secondary analysis of d

A comparative study of satellite altimetry-based and DEM-based methods for estimating lake water volume changes

This study compared two different methods, the satellite altimetry-based and DEM (digital elevation model)-based, for estimating lake water volume changes. We focused on 34 lakes in China as the testing sites to compare the two methods for lake water volume changes from 2005 to 2020. The satellite altimetry-based method used water levels provided by the DAHITI (Database for Hydrological Time Serie

The ‘Wellbeing Wardrobe’ as a tool to promote just transitions in the fashion and textile industry

In this paper we discuss the pressing need for a just transition in one of our most environmentally and socially problematic contemporary industries: the fashion and textiles industry. We detail the current injustices in the industry, from both environmental and socio-economic standpoints, and then move on to providing some suggestions as to how these entrenched problems with the industry could be

Towards carbon neutrality : Transition pathways for the Chinese ethylene industry

Ethylene is one of the most important products in the emissions-intensive petrochemical industry. Decarbonizing the ethylene industry is thus important for achieving global carbon neutrality. This study is the first to explore future long-term zero-emissions production pathways for the ethylene industry in China, the world's biggest ethylene producer. An optimization model was built in the context

Effekter av branschöverenskommelsen för den fossilfria leveransen: nuläge och vägar framåt

The Swedish retail landscape is currently undergoing a transformative change with increased digitalization and a rapidly growing e-commerce sector, which creates both opportunities and challenges. The development towards omnichannel commerce creates a more complex customer journey and results in complex environmental challenges. E-commerce deliveries to consumers, in particular, pose a complex soc

Genome-wide investigation of persistence with methotrexate treatment in early rheumatoid arthritis

Objectives: To investigate the influence of genetic factors on persistence with treatment of early RA with MTX monotherapy. Methods: We conducted a genome-wide association study (GWAS) in a sample of 3902 Swedish early-RA patients initiating MTX in DMARD monotherapy as their first-ever DMARD. The outcome, short-and long-Term MTX treatment persistence, was defined as remaining on MTX at 1 and at 3
