Changes in apparent diffusion coefficient and pathological response in colorectal liver metastases after preoperative chemotherapy

Background: The pathological response to preoperative chemotherapy of colorectal liver metastases (CRLMs) is predictive of long-term prognosis after liver resection. Accurate preoperative assessment of chemotherapy response could enable treatment optimization. Purpose: To investigate whether changes in lesion-apparent diffusion coefficient (ADC) measured with diffusion-weighted magnetic resonance

Base of tongue squamous cell carcinomas, outcome depending on treatment strategy and p16 status. A population-based study from the Swedish Head and Neck Cancer Register

Background: The base of tongue squamous cell carcinoma (BOTSCC) is mainly an HPV-related tumor. Radiotherapy (EBRT) ± concomitant chemotherapy (CT) is the backbone of the curatively intended treatment, with brachytherapy (BT) boost as an option. With four different treatment strategies in Sweden, a retrospective study based on the population-based Swedish Head and Neck Cancer Register (SweHNCR) wa

On the sign recovery by least absolute shrinkage and selection operator, thresholded least absolute shrinkage and selection operator, and thresholded basis pursuit denoising

Basis pursuit (BP), basis pursuit deNoising (BPDN), and least absolute shrinkage and selection operator (LASSO) are popular methods for identifying important predictors in the high-dimensional linear regression model (Formula presented.). By definition, when (Formula presented.), BP uniquely recovers (Formula presented.) when (Formula presented.) and (Formula presented.) implies (Formula presented

Upregulated Retinal Neurofilament Expression in Experimental Optic Neuritis

In optic neuritis (ON), transient thickening of the macular retinal nerve fibre layer (RNFL) can be observed. This optical coherence tomography-based observation is not understood. The axonal diameter correlates with the neurofilament (Nf) protein content, but there are no data on the retinal tissue concentration of Nfs. The myelin-oligodendrocyte-glycoprotein (MOG) induced experimental autoimmune

Training leaders for the future? Leadership models for emerging and aspiring civil society leaders in Sweden and the UK

This article aims to understand the prevalent leadership models in seven prominent leadership development programmes targeting emerging and aspiring civil society leaders in Sweden and the United Kingdom (UK), which have two different civil society regimes. An analytical framework based on ideal-typical leadership models (transactional, transformational and collaborative) helps us distil how progr

Pain, Function, and Satisfaction After Total Knee Arthroplasty, with or Without Bariatric Surgery

Background: The impact of obesity on patient-reported outcome (PRO) after total knee arthroplasty (TKA) surgery has demonstrated varying results. We evaluated knee pain, Activity in Daily Life function (ADL), and satisfaction after TKA surgery in patients with and without prior bariatric surgery (BS). Methods: Scandinavian Obesity Surgery Registry (SOReg) and the Swedish Knee Arthroplasty Register

Drifting pitch awareness after exposure to altered auditory feedback

Various studies have claimed that the sense of agency is based on a comparison between an internal estimate of an action’s outcome and sensory feedback. With respect to speech, this presumes that speakers have a stable prearticulatory representation of their own speech. However, recent research suggests that the sense of agency is flexible and thus in some contexts we may feel like we produced spe

Transcriptomic analysis of functional diversity of human umbilical cord blood hematopoietic stem/progenitor cells in erythroid differentiation

Hematopoietic stem cells (HSC) give rise to all types of blood lineages, including red blood cells (RBC). Hematopoietic stem/progenitor cells (HSPC) are known to be functionally diverse in terms of their self-renewal potential and lineage output. Consequently, investigation of molecular heterogeneity in the differentiation potential of HSPC is vital to identify novel regulators that affect generat

Student Housing in Europe - Country Report for Sweden

This chapter contains an overview of general policies regarding student housing in Sweden, a desription of market conditions for students renting a room or an apartment, and the legal framework regulating student housing in Sweden, including the rental contract.

Circulating Markers of Neutrophil Extracellular Traps (NETs) in Patients With Ovarian Tumors

BACKGROUND/AIM: Inflammation is a hallmark of cancer, and the role of neutrophils and neutrophil extracellular traps (NETs) in cancer and cancer-associated thrombosis has attracted a lot of interest. The NET-specific marker H3Cit has been found to be elevated in the plasma of patients with malignancies, suggesting NETs markers as novel cancer biomarkers. This study aimed to determine the levels of

Improved Electrostatics through Digital Etch Schemes in Vertical GaSb Nanowire p-MOSFETs on Si

Sb-based semiconductors are critical p-channel materials for III-V complementary metal oxide semiconductor (CMOS) technology, while the performance of Sb-based metal-oxide-semiconductor field-effect transistors (MOSFETs) is typically inhibited by the low quality of the channel to gate dielectric interface, which leads to poor gate modulation. In this study, we achieve improved electrostatics of ve

Late stabilization after initial migration in patients undergoing cemented total knee arthroplasty : a 5-year followup of 2 randomized controlled trials using radiostereometric analysis

BACKGROUND AND PURPOSE: In total knee arthroplasty (TKA), metal-backed (MBT) and all-polyethylene (APT) designs have shown comparable implant migration up to 2 years postoperatively using radiostereometric analysis (RSA). However, studies comparing mid-term migration of both designs are lacking. Furthermore, continuously migrating TKAs up to 2 years may continue to migrate or stabilize thereafter.

Lessons Learned from a Study on Distractions in Virtual Learning Environments : Reliability, Ecological Validity, and an Elusive Social Component

Virtual Reality has long been proposed to combine the reliability of controlled laboratory settings with the ecological validity of real life. While the technological development steadily pushes towards even more realistic renderings of the real world— the elusiveness of social and emotional elements gradually becomes more evident. This is not the least true for behavioral studies in rich sociocul

Being Young in the Diaspora : Fragmentation of the Palestinian Youth Mobilisation from the Middle East to Europe

While the current research mainly deals with the Palestinian youth in the Middle East, reports from various organisations, whose most accounts are descriptive, hardly provide a sustained and critical evaluation of their nature and impact. With an urgent need to understand better youth engagement in exile under adverse conditions in a conflict-ridden society such as the Palestinian one, this paper

Gaming Activity and Possible Changes in Gaming Behavior Among Young People During the COVID-19 Pandemic : Cross-sectional Online Survey Study

Background: Young people's daily lives and social interactions changed remarkably during the COVID-19 pandemic as schools and cinemas closed, leisure activities were cancelled, and gatherings were regulated. Questions have been raised by the media, schools, policy makers, and research communities about the effect on young people's online behaviors. Objective: This cross-sectional study aimed to st

Secure Ownership Transfer for Resource Constrained IoT Infrastructures

Internet of Things or IoT deployments are becoming more and more common. The list of use-cases for IoT is getting longer and longer, but some examples are smart home appliances and wireless sensor networks. When IoT devices are deployed and used over an extended time, it is not guaranteed that one owner will control the IoT devices over their entire lifetime. If the ownership of an IoT system shal

Agility in Software 2.0 – Notebook Interfaces and MLOps with Buttresses and Rebars

Artificial intelligence through machine learning is increasingly used in the digital society. Solutions based on machine learning bring both great opportunities, thus coined “Software 2.0,” but also great challenges for the engineering community to tackle. Due to the experimental approach used by data scientists when developing machine learning models, agility is an essential characteristic. In th

Monopsony power and wages: Evidence from the introduction of serfdom in Denmark

We exploit a large historical shock to the Danish labour market to provide evidence of how restrictions on labour mobility increase monopsony power and thereby reduce wages. By severely limiting the possibility of the rural population to work beyond their place of birth, the reintroduction of serfdom in 1733 aimed to increase monopsony power and secure cheaper labour in the countryside. Using a un

Juvenile idiopathic arthritis - from macrophage to mortality

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. Studies of the immunopathogenesis in JIA has mainly focused on the adaptive immune system, while less is known of the role of the monocytes. JIA is considered a chronic disease, although only about 50% of participants in long-term follow-up studies have active disease as adults. The treatment arsenal for JIA has
