Polymorphisms in Intron 1 of HLA-DRA Differentially Associate with Type 1 Diabetes and Celiac Disease and Implicate Involvement of Complement System Genes C4A and C4B

Polymorphisms in genes in the human leukocyte antigen (HLA) class II region comprise the most important inherited risk factors for many autoimmune diseases including type 1 diabetes (T1D) and celiac disease (CD): both diseases are positively associated with the HLA- DR3 haplotype (DRB1*03:01-DQA1*05:01-DQB1*02:01). Studies of two different populations have recently documented that T1D susceptibili

A cathodoluminescence study of InP/InGaP axially heterostructured NWs for tandem solar cells

Axially heterostructured nanowires (NWs) constitute a promising platform for advanced electronic and optoelectronic nanodevices. The presence of different materials in these NWs introduces a mismatch resulting in complex strain distributions susceptible of changing the band gap and carrier mobility. The growth of these NWs presents challenges related to the reservoir effect in the catalysts drople

Modeling Photofunctional Transition Metal Complexes

Transition metal complexes play a crucial role in solar energy conversion. These coordination compounds have promising applications in dye-sensitized solar cells and photocatalysis, with particular interest in solar fuel production. However, many of the photoactive transition metal complexes used in light-harvesting applications are still based on rare and expensive metals from the transition meta

The AAV-α-Synuclein Model of Parkinson's Disease : An Update

Targeted delivery of α-synuclein using AAV vectors has over the two decades since its introduction developed into a versatile tool for modeling different aspects of synucleinopathy, mimicking those seen in Parkinson's disease and related Lewy body disorders. The viral vector approach to disease modeling is attractive in that the expression of α-synuclein, wild-type or mutated, can be confined to d

Sodium Intake and Incident Atrial Fibrillation in Individuals With Vascular Disease

IMPORTANCE Numerous prospective cohort studies have reported a J-shaped association of urinary sodium excretion with cardiovascular events and mortality. OBJECTIVE To study the association between sodium intake and incident atrial fibrillation (AF). DESIGN, SETTING, AND PARTICIPANTS This cohort study included participants in the Ongoing Telmisartan Alone and in Combination with Ramipril Global End

Eckart streaming with nonlinear high-order harmonics : An example at gigahertz

Acoustic streaming shows great potential in applications such as bubble dynamics, cell aggregation, and nanosized particle isolation in the biomedical and drug industries. As the acoustic shock distance decreases with the increase of incident frequency, the nonlinear propagation effect will play a role in acoustic streaming, e.g., Eckart (bulk) streaming at a few gigahertz. However, the theory of

Association between attending exercisebased cardiac rehabilitation and cardiovascular risk factors at one-year post myocardial infarction

Background: Randomized trials confirm the benefits of exercise-based cardiac rehabilitation on cardiovascular risk factors. Whether exercise-based cardiac rehabilitation provides the same favourable effects in real-life cardiac rehabilitation settings, in the modern era of myocardial infarction treatment, is less well known. We examined the association between attending exercise-based cardiac reha

Prognostic Impact of Menopausal Hormone Therapy in Breast Cancer Differs According to Tumor Characteristics and Treatment

This study investigated how a history of menopausal hormone therapy (MHT) impacts clinical outcomes overall and in different subgroups of breast cancer patients. The study included 814 primary breast cancer patients aged ≥50 years in Sweden (2002–2012) with follow-up until 2016. Associations between patient- and tumor characteristics, recurrences, and overall survival were analyzed in relation to

Modeling of Polarization-Selective Light-Coupling in Quantum Well Infrared Photodetectors with Small Pixel Sizes

Herein, a model is developed to study the polarization-selective light-coupling in quantum well infrared photodetector arrays with 15 and 30 μm pixel pitch. The polarization-selective light-coupling is achieved using 1D lamella gratings with varying grating orientation and studied through 2D and 3D finite-element method simulations. The extracted absorption quantum efficiency ηabs, derived from th

Imaging ferroelectric domains with soft-x-ray ptychography at the oxygen K-edge

The ferroelectric domain structure of a freestanding BiFeO3 film was visualized by ptychographic dichroic imaging with linearly polarized x-rays at the O K-edge around 530 eV. The dichroic contrast is maximized at the energy of the hybridization of the O 2p state and the Fe 3d orbitals, which is split by the octahedral crystal field of the perovskite structure. The microscopy images thus obtained

Thermal Considerations in Bulk Acoustic Wave Devices towards Optimised Acoustofluidics

The main goal of my studies was obtaining bulk acoustofluidic devices able to achieve high energy density inside a water-filled cavity. This led us to explore the interplay of sound and thermal effects more in details. Hence, this thesis covers both thermoacoustic effects in Bulk Acoustic Wave devices and a revisited approach for designing them, focusing on achieving good performance. Thermoacoust

Generation of Human 3D Lung Tissue Cultures (3D-LTCs) for Disease Modeling

Translation of novel discoveries to human disease is limited by the availability of human tissue-based models of disease. Precision-cut lung slices (PCLS) used as 3D lung tissue cultures (3D-LTCs) represent an elegant and biologically highly relevant 3D cell culture model, which highly resemble in situ tissue due to their complexity, biomechanics and molecular composition. Tissue slicing is widely

The Preparation of Decellularized Mouse Lung Matrix Scaffolds for Analysis of Lung Regenerative Cell Potential

Lung transplantation is the only option for patients with end-stage lung disease, but there is a shortage of available lung donors. Furthermore, efficiency of lung transplantation has been limited due to primary graft dysfunction. Recent mouse models mimicking lung disease in humans have allowed for deepening our understanding of disease pathomechanisms. Moreover, new techniques such as decellular

Aim: To analyze the risk of subsequent or simultaneous cancers in women with BOTs compared with the general female Swedish population. Methods: An open cohort study (1995–2018) was conducted where a diagnosis of BOTs as wel

On the interactions between RNA and titrateable lipid layers : implications for RNA delivery with lipid nanoparticles

Characterising the interaction between cationic ionisable lipids (CIL) and nucleic acids (NAs) is key to understanding the process of RNA lipid nanoparticle (LNP) formation and release of NAs from LNPs. Here, we have used different surface techniques to reveal the effect of pH and NA type on the interaction with a model system of DOPC and the CIL DLin-MC3-DMA (MC3). At only 5% MC3, differences in

Hodgkin lymphoma after autoimmune diseases by age at diagnosis and histological subtype

Increased risk of Hodgkin lymphoma (HL) associated with personal history of several autoimmune diseases (ADs), such as rheumatoid arthritis, systemic lupus erythematosus, sarcoidosis, and immune thrombocytopenic purpura, are known. Whether there are other HL-related ADs and whether the increased risk of HL after ADs holds across sex, age, year of diagnosis, or HL histological subtype is unclear. W
