Context. Stellar evolution models predict that internal mixing should cause some sodium overabundance at the surface of red giants more massive than ~1.5-2.0 M⊙. The surface aluminium abundance should not be affected. Nevertheless, observational results disagree about the presence and/or the degree of Na and Al overabundances. In addition, Galactic chemical evolution models adopting different stel

Importance: High gluten intake during childhood may confer risk of celiac disease. Objectives: To investigate if the amount of gluten intake is associated with celiac disease autoimmunity and celiac disease in genetically at-risk children. Design, Setting, and Participants: The participants in The Environmental Determinants of Diabetes in the Young (TEDDY), a prospective observational birth cohort

Non-traditional stable isotope systems are increasingly used to study micronutrient cycling and acquisition in terrestrial ecosystems. We previously proposed for zinc (Zn) a conceptual model linking observed isotope signatures and fractionations to biogeochemical processes occurring in the rice soil environment and we suggested that 2’deoxymugineic acid (DMA) could play an important role for rice

Introduction. Limited information is available concerning the general and sexual health status of European men. Aim. To investigate the age-related changes in general and sexual health in middle-aged and older men from different countries of the European Union. Methods. This is a cross-sectional multicenter survey performed on a sample of 3,369 community-dwelling men aged 40-79 years old (mean 60

Introduction: The transition from pediatric to adult healthcare represents a crucial period for adolescents and youth living with HIV. When this healthcare transition is not properly managed, it can result in negative outcomes such as loss to follow-up (LTFU), increased morbidity, and mortality. Therefore, it is essential to estimate the incidence rate and identify predictors of loss to follow-up

Aims. We study how diffuse interstellar bands (DIBs) measured toward distance-distributed target stars can be used to locate dense interstellar (IS) clouds in the Galaxy and probe a line-of-sight (LOS) kinematical structure, a potentially useful tool when gaseous absorption lines are saturated or not available in the spectral range. Cool target stars are numerous enough for this purpose. Methods.

PURPOSE:: To describe a family with an 18-year-old woman with fundus albipunctatus and compound heterozygous mutations in RPE65 whose unaffected parents and 1 female sibling harbored single heterozygous RPE65 mutations. DESIGN:: Observational study. PARTICIPANTS:: Four family members. METHODS:: Clinical examinations included full-field electroretinogram (ffERG) after standard (30-minute) and prolo

Världen är i ständig miljö- och hälsofrämjande utveckling, där ny forskning och upptäckter hela tiden driver marknadskrav och bidrar till restriktioner. Plastindustrin har länge varit under luppen, till stor del för fossila råvaror och nedskräpning, men även då vissa plastmaterial innehåller ifrågasatta tillsatser. Flexibel Polyvinylklorid (PVC) är en typ av plast som används mycket i dagens samhFlexible Polyvinyl chloride (PVC) is a plastic material commonly used in today’s society and a fundamental material for a lot of sectors. It has advantages over other polymers such as energy-efficient production, flame retardancy, durability and cost-effective. The one important component in flexible PVC that gives it is flexible properties is the plasticizer. The most common plasticizers used are

Background About 30% of cases of chronic lymphocytic leukaemia (CLL) carry quasi-identical B-cell receptor immunoglobulins and can be assigned to distinct stereotyped subsets. Although preliminary evidence suggests that B-cell receptor immunoglobulin stereotypy is relevant from a clinical viewpoint, this aspect has never been explored in a systematic manner or in a cohort of adequate size that wou

Background Coronary artery disease is one of the most common causes of death. A common cardiac examination is to give a visualization of the myocardial blood flow by injecting a radio pharmaceutical and detect the radiation with a camera. The camera has for decades been using thallium doped sodium iodide (NaI(Tl)) as the detector material. New detector materials have been developed because of the

This thesis encompasses an introductory part and five papers related to developing techniques and phantoms required for the further growth of photoacoustic imaging (PAI). In PAI, images are created by detecting acoustic waves followed by the absorption of laser light, enabling high spatial resolution while maintaining high optical contrast. Due to the distinct absorption patterns of various chromo

Polymer electrolyte membrane fuel cells (PEMFCs) fueled by hydrogen are considered to be most suitable for automotive applications owing to their fast dynamics and high power densities. However, the performances are limited primarily by processes in PEMFCs appeared in the catalyst layers (CLs), which highly dependon themicroscopic structure-related properties.TheCLs at both the anode and cathode h

BACKGROUND: High carbohydrate intake raises blood triglycerides, glucose, and insulin; reduces HDLs; and may increase risk of coronary heart disease (CHD). Epidemiological studies indicate that high dietary glycemic index (GI) and glycemic load (GL) are associated with increased CHD risk. OBJECTIVES: The aim of this study was to determine whether dietary GI, GL, and available carbohydrates are ass
