The exceptional polymorphism observed within genes of the major histocompatibility complex (MHC), a core component of the vertebrate immune system, has long fascinated biologists. The highly polymorphic classical MHC class-I (MHC-I) genes are maintained by pathogen-mediated balancing selection (PMBS), as shown by many sites subject to positive selection, while the more monomorphic non-classical MH
With Euro50 as a convenient telescope laboratory, the Euro50 team has continued development aiming at a European extremely large telescope (ELT). Here, we give a progress report. The needs of science and instrumentation are briefly discussed as is the importance of photometric stability and precision. Results are reported from work on integrated modelling. Details are given concerning point-spread
This chapter ". . . looks at a problem that is an important effect of systemic features: the problems of defining clear boundaries between different types of actors. Richard Langlais and Sharon Rider study the boundary between research performed by public universities and companies basing their technology on scientific research. They use the concept "science machines" to depict those systems of so
In this work a compact fluorosensor has been built for point-monitoring and imaging applications. The instrument has been applied in fluorescence studies on green vegetation and on malignant tissue. The instrument is based on a violet diode laser, an integrated spectrometer and optical fibers for light delivery and collection of the fluorescence signal. This combination makes the system very compa
This chapter introduces systematic reviews and provides a summary of systematic review methods. Because of the challenges in palliative care trials, systematic reviews might be even more relevant in palliative care than in many other areas of health care. This chapter highlights the reasons why a researcher should use a systematic review, as well as the instances when systematic reviews are not an
Background Long-term pathological breathlessness is a life-limiting symptom that risks taking control of the individual’s life. We aimed to evaluate how locus of control (LOC), an individual’s perceived control of present and past life events, relates to breathlessness in a middle-aged general population. Methods A population-based, cross-sectional analysis of people aged 50–64 years was conducted
BACKGROUND: As the global population ages, the demand for palliative care is expected to increase. However, studies show that older patients often receive inadequate palliative care, partly due to healthcare professionals lacking sufficient training and tools to identify and address palliative care needs effectively. This study aims to explore healthcare professionals' experiences regarding facili
Artificial intelligence (AI) applications are increasingly seeing use in breast imaging, particularly to assist in or automate the reading of mammograms. Another novel technique is mechanical imaging (MI) which estimates the relative stiffness of suspicious breast abnormalities by measuring the distribution of pressure on the compressed breast. This study investigates the feasibility of combining
INTRODUCTION: While the characteristics and medical management of patients treated with long-term oxygen therapy (LTOT) have transformed during the last decades, the evidence base for LTOT itself remains largely unchanged. This study aimed to compare the risk of hospitalization and death among hypoxemic patients discontinuing LTOT, with that of controls continuing therapy.METHODS: This was a retro
ObjectivesUncertainty among healthcare providers about patients’ ability to make care decisions is a barrier to shared decision-making. We aimed to assess the self-reported decision-making ability of patients with cancer at the end of life.MethodsData from 11 countries of adults with a limited life expectancy and cancer as the primary diagnosis were used. Participants completed a questionnaire, in
The X-ray scanning microscope PtyNAMi at beamline P06 of PETRA III at DESY in Hamburg, Germany, is designed for high-spatial-resolution 3D imaging with high sensitivity. Besides optimizing the coherent ux density on the sample and the precision mechanics of the scanner, special care has been taken to reduce background signals on the detector. The optical path behind the sample is evacuated up unti
Aim: The aim of this study was to evaluate the therapeutic efficacy and safety profile of orally administered low-dose ketamine for procedural pain management in pediatric cancer patients undergoing lumbar puncture (LP) in a resource-limited hospital setting. Methods: Patients between 4 and 15 years of age, with leukemia, undergoing LP were asked to participate. The study was designed as a two-a
In mitosis, transcription factors (TFs) and RNA polymerase disperse across the cytoplasm leading to transcriptional silencing, but some TFs are retained on condensed chromatin and mark genomic sites, a mechanism termed mitotic bookmarking. In pluripotent and differentiated cells this mechanism is important for pluripotency maintenance, cell reprogramming and lineage inheritance. However, the role
Health information system (HIS) refers to a data collection and management system that supports the use of health information for planning, management and decision making. Robust HISs are required for the proper management of health data to produce and share high-quality health information for informing planning and decision making at different levels of the health system. This chapter presents th
Background: Deferral of coronary revascularization is safe whether guided by instantaneous wave-free ratio (iFR) or by fractional flow reserve (FFR). We aimed to assess long-term outcomes in patients deferred from revascularization based on iFR or FFR in a large real-world population. Methods: From 2013 through 2017, 201,933 coronary angiographies were registered in the Swedish Web-System for Enha
Genome-wide association studies (GWAS) have transformed our understanding of susceptibility to multiple myeloma (MM), but much of the heritability remains unexplained. We report a new GWAS, a meta-analysis with previous GWAS and a replication series, totalling 9974 MM cases and 247,556 controls of European ancestry. Collectively, these data provide evidence for six new MM risk loci, bringing the t
