Optimization of MoRe contacts to InGaAs Quantum Wells

This thesis presents the design, fabrication, and characterization of molybdenum–rhenium (MoRe) based MOSFET on InAlAs and InGaAs heterostructures, aiming to integrate superconducting contacts with III–V semiconductors for hybrid quantum compatible devices. The study addresses interfacial challenges that limit contact transparency and investigates different surface preparation and passivation tech

Discovery and engineering of the antibody response to a prominent skin commensal

The ubiquitous skin colonist Staphylococcus epidermidis elicits a CD8+ T cell response pre-emptively, in the absence of an infection1. However, the scope and purpose of this anticommensal immune programme are not well defined, limiting our ability to harness it therapeutically. Here, we show that this colonist also induces a potent, durable and specific antibody response that is conserved in human

A vaccine combination of lipid nanoparticles and a cholera toxin adjuvant derivative greatly improves lung protection against influenza virus infection

This is a proof-of-principle study demonstrating that the combination of a cholera toxin derived adjuvant, CTA1-DD, and lipid nanoparticles (LNP) can significantly improve the immunogenicity and protective capacity of an intranasal vaccine. We explored the self-adjuvanted universal influenza vaccine candidate, CTA1-3M2e-DD (FPM2e), linked to LNPs. We found that the combined vector greatly enhanced

Therapeutic impact of leuprorelin acetate on spinal and bulbar muscular atrophy : pre- and post-marketing observational study

Although leuprorelin acetate, a luteinizing hormone-releasing hormone agonist, has been approved based on short-term clinical trials conducted in Japan, its long-term efficacy on physical function remains unclear. We aimed to evaluate the long-term therapeutic efficacy of leuprorelin acetate using real-world clinical data through a self-controlled trend-shift analysis. The analysis included 91 gen

Cross-Protective Potential and Protection-Relevant Immune Mechanisms of Whole Inactivated Influenza Virus Vaccines Are Determined by Adjuvants and Route of Immunization

Adjuvanted whole inactivated virus (WIV) influenza vaccines show promise as broadly protective influenza vaccine candidates. Using WIV as basis we assessed the relative efficacy of different adjuvants by carrying out a head-to-head comparison of the liposome-based adjuvants CAF01 and CAF09 and the protein-based adjuvants CTA1-DD and CTA1-3M2e-DD and evaluated whether one or more of the adjuvants c

Home-based Hybrid Assistive Limb Lumbar Type Telerehabilitation in Spinocerebellar Ataxias : A Nonrandomized Open-label Trial

A hybrid assistive limb (HAL) can improve the motor performance of patients with various neurodegenerative diseases, but the efficacy of home-based rehabilitation using HAL for spinocerebellar ataxias (SCA) has yet to be elucidated. To evaluate the efficacy and safety of home-based telerehabilitation with lumbar type HAL in patients with SCA. In this non-randomized open-label single center trial,

Detoxified synthetic bacterial membrane vesicles as a vaccine platform against bacteria and SARS-CoV-2

The development of vaccines based on outer membrane vesicles (OMV) that naturally bud off from bacteria is an evolving field in infectious diseases. However, the inherent inflammatory nature of OMV limits their use as human vaccines. This study employed an engineered vesicle technology to develop synthetic bacterial vesicles (SyBV) that activate the immune system without the severe immunotoxicity

Class-switch recombination to IgA in the Peyer's patches requires natural thymus-derived Tregs and appears to be antigen independent

Our understanding of how class-switch recombination (CSR) to IgA occurs in the gut is still incomplete. Earlier studies have indicated that Tregs are important for IgA CSR and these cells were thought to transform into follicular helper T cells (Tfh), responsible for germinal center formation in the Peyer's patches (PP). Following adoptive transfer of T-cell receptor-transgenic (TCR-Tg) CD4 T cell

Multiobjective Bayesian optimization on HPGR

When applying Bayesian optimization (BO) algorithms which utilizes Gaussian processes (GP) models, several components can be adapted to suit different systems and optimization objectives. In this paper, we explore and evaluate a set of such modifications to tailor the algorithm for a high-pressure grinding rolls (HPGR) system. The system is represented by a steady-state simulator modeling the HPGR

Fusions4U: a resource of validated and annotated gene fusions in 328 cancer cell lines

BackgroundLarge-scale genomic rearrangements in cancer cells can lead to the creation of fusion genes which alter the expression or function of the partner genes. Some fusion genes act as tumour drivers and the use of kinase inhibitors in patients with specific fusions have led to breakthroughs in cancer therapy. The large clinical and scientific interest in fusions has led to the development of s

Clinical Decision-Making of Artificial Intelligence vs Medical Professionals in Patients With Syncope

BACKGROUND: Artificial intelligence may improve diagnostic yield and accuracy in syncope.OBJECTIVES: The purpose of this study was to compare Generative Pretrained Transformer 4-Omni (GPT-4o) with medical professionals (MPs) in establishing syncope diagnoses and recommending interventions based on general practitioner's referral letters to a syncope-unit.METHODS: This three-phase study evaluated 5

Embryological cellular origins and hypoxia-mediated mechanisms in PIK3CA-driven refractory vascular malformations

Congenital vascular malformations, affecting 0.5% of the population, often occur in the head and neck, complicating treatment due to the critical functions in these regions. Our previous research identified distinct developmental origins for blood and lymphatic vessels in these areas, tracing them to the cardiopharyngeal mesoderm (CPM), which contributes to the development of the head, neck, and c

Both synergism and interaction diversity explain the mixtures of defensive monoterpenes in spruce oleoresin

Chemical defences, such as the monoterpenes of conifer oleoresin, frequently occur as complex blends of many components, but the selective pressures that maintain these mixtures are not yet known. Several theories attempt to explain the existence of chemical defence mixtures in plants. However, due to limited empirical evidence, it is unclear which theories might best apply. Here, we tested the va

Patterns of molecular and morphological variation in Mentha subgen. Mentha (Lamiaceae)—materials for a global taxonomic revision

Based on a combination of morphometric analyses, a chloroplast DNA phylogeny, and multivariate analyses of whole genome sequence data from >300 museum samples, we discuss and evaluate the delimitation, taxonomy, and evolution of wild and escaped taxa in Mentha subgen. Mentha, focusing on the northern hemisphere. Thirteen species (Mentha aquatica, M. arvensis, M. australis, M. capensis, M. dahurica

Index theory of differential operators in noncommutative geometry

This thesis explores index theory for linear differential operators using tools from noncommutative geometry. We study how spectral triples can accommodate elliptic and Heisenberg-elliptic higher-order differential operators in K-homology, with a specific focus on manifolds with boundary. In the case of higher-order elliptic differential operators on manifolds with smooth compact boundary, we prov

Heterogeneity of the intestinal mononuclear phagocyte compartment in health and inflammatory bowel disease

Understanding of mononuclear phagocyte (MNP) diversity in the human intestine and the alterations this compartment undergoes in inflammation remains incomplete. Here, we used single-cell RNA sequencing, cellular indexing of trancriptomes and epitopes by sequencing, flow cytometry, and imaging to explore MNP heterogeneity in human ileal and colonic laminae propriae (LPs) in health and Crohn's disea

Revised European Society of Endocrinology Clinical Practice Guideline for the management of aggressive pituitary tumours and pituitary carcinomas

Pituitary tumours, originating from endocrine cells of the anterior pituitary, are quite common, and in most cases well-controlled by surgery or medical treatment. However, a small subset of pituitary tumours presents with multiple local recurrences or tumour progression despite combined surgical, medical or radiotherapeutic treatment. These are known as aggressive pituitary tumours (APT); also ca
