We present electronic band structure properties of strained InxGa(1-x)As/InP heterostructure near surface quantum wells oriented in the (100) crystallographic direction using eight-band k · p theory, which are further parameterized by an energy level, effective mass, and nonparabolicity factor. The electronic band structure parameters are studied for the well composition of 0.2 ≤ x ≤ 1 and thickne
Antibody microarray technology has the potential for playing a large roll in identifying serological biomarker panels for personalized medicine. The aim of this thesis, based on four original papers, was to investigate if information in the serum proteome could be extracted and used for diagnostic, classificational, prognostic or treatment predictive purposes in a range of diseases. In two studies
Cesium lead halides are a family of bright, visible-light emitting materials with near-unity photoluminescence quantum yield (PLQY) in nanocrystals (NCs). The usual way to achieve visible light-emission tunability is by mixing halides, which often leads to phase separation and poor stability. While the NCs should also show size-dependent PL emission, reports on strong quantum confinement in these
Objective: It has been proposed that endogenous sex hormone levels may present a modifiable risk factor for cognitive decline. However, the evidence for effects of sex steroids on cognitive ageing is conflicting. We therefore investigated associations between endogenous hormone levels, androgen receptor CAG repeat length, and cognitive domains including visuoconstructional abilities, visual memory
Humans are exposed to various metals through many different routes and each person’s genetic background contributes to their susceptibility to metal toxicity. In addition, recent evidence points to a role for the genetics of the human microbiome in metal uptake and toxicity. DNA sequence variation in genes that regulate metal toxicokinetics and toxicodynamics influences metal accumulation and rete
Aims: To investigate associations between trust in the healthcare system and all-cause, cardiovascular, cancer and other causes mortality. Study design: Prospective cohort study. Methods: A public health questionnaire was conducted in 2008 in Scania, the southernmost part of Sweden, with a 54.1% participation rate with a postal questionnaire and three reminders. In this study 24,833 respondents we

Background: – The use of antibiotic-loaded bone cement (ALBC) in primary total knee arthroplasty (TKA) is debated. Some argue that ALBC might only be justified in high-risk patients. This study assessed the effectiveness of ALBC vs. plain bone cement (PBC) in reducing risk of revision for periprosthetic joint infection (PJI) in TKA patients considered to have a high risk of infection.Methods: – Co
Background and purpose —The use of a tourniquet in knee replacement surgery is debated. Given the conflicting evidence, we aimed to compare the risk of revision after total knee replacements (TKR) with or without the use of tourniquet. Methods — In this register based observational study, we included the 5 most common cemented primary TKR models due to osteoarthritis reported to the Swedish Arthro
Aim: To evaluate the impact of initial mono- versus multitherapy on the ocular surface and related quality of life after 5 years follow-up in the Glaucoma Intensive Treatment Study (GITS). Method: The study included patients with primary open-angle glaucoma and pseudoexfoliation glaucoma who completed 5-year follow-up in GITS. Assessment of ocular surface disease (OSD) symptoms was done using a Sw
Objective: The aim of this study was to investigate the experiences of school nurses working with refugee children from Ukraine. Design: This research was conducted as a qualitative interview study, using an inductive approach and a semi-structured interview guide. Sample: School nurses (n = 8) from different parts of Sweden were interviewed, and the data were analyzed through a qualitative conten
BackgroundAcute-phase proteins (APPs) reflect systemic inflammation and nutritional status, yet their perioperative trajectories and clinical utility as biomarkers of outcome in advanced ovarian cancer (aEOC) remain unclear. We aimed to characterise perioperative APP fluctuations and assess their associations with postoperative complications.MethodsThis observational study included patients underg
This reflective commentary, based on long-term experience in UK higher education, proposes a novel approach to using a wicked problem model to develop policy and practice within higher education. The aim of this approach is to reframe the narrative of strategic development to acknowledge the complexity of cultural change and the importance of stakeholder consultation to build trust, moving away fr
BACKGROUND: Trigger finger surgery typically has a successful outcome, also in patients with diabetes mellitus (DM). However, the impact of glycemic control on long-term outcomes after open trigger finger release (OTFR) remains unclear. This study examines whether high hemoglobin A1c (HbA1c) levels affect patient-reported outcome (PRO) following OTFR in individuals with type 1 diabetes mellitus (T
INTRODUCTION: Stroke is a leading cause of death and disability worldwide. Recurrent strokes are seven times more lethal than initial ones, with 54% leading to long-term disability. Substantial recurrent stroke risk disparities exist among ancestral groups. Notably, Africans face double the risk and higher fatality rates compared to Europeans. Although genetic studies, particularly GWAS, hold prom
Introduction: HIV guidelines recommend switching from a three-drug regimen (3DR) to dolutegravir + lamivudine (DTG+3TC) for eligible individuals. This retrospective national cohort study used Swedish InfCareHIV registry data to evaluate long-term outcomes of adults with HIV RNA <50 copies/ml who switched to DTG+3TC or a guideline-recommended 3DR between July 2019 and May 2023 in routine clinical c
Background: Over time, family structures have grown more complex, diversifying adult relationships. While research has compared marital, cohabiting and living apart together relationships based on quality and health, less is known about their sexual dynamics. Theoretical frameworks suggest that co-resident relationships may integrate sexuality differently from living apart together unions, where p
Spectral editing with CP and INEPT in (13)C MAS NMR enables identification of rigid and mobile molecular segments in concentrated assemblies of surfactants, lipids, and/or proteins. In order to get stricter definitions of the terms "rigid" and "mobile", as well as resolving some ambiguities in the interpretation of CP and INEPT data, we have developed a theoretical model for calculating the CP and
