Pituitary function after high-dose 177Lu-DOTATATE therapy and long-term follow-up
INTRODUCTION: The pituitary gland has a high expression of somatostatin receptors (SSTRs) and is therefore a potential organ at risk for radiation-induced toxicity after 177Lu-DOTATATE treatment.OBJECTIVE: To study changes in pituitary function in patients with neuroendocrine tumors (NETs) treated with dosimetry-based 177Lu-DOTATATE to detect possible late toxicity.METHODS: 68 patients from a phas
Novel Evidence Concerning Lacrimal Sac Movement Using Ultra-High-Frequency Ultrasound Examinations of Lacrimal Drainage Systems
PURPOSE: Current hypothesis regarding the mechanism of active tear drainage is based on studies performed ex vivo or under nonphysiological conditions. Novel ultra-high-frequency ultrasound has the advantage of generating images with superior resolution, enabling measurements of low flow in small vessels, and the tracking of tissue motion in real time. The purpose of this study was to investigate
Serum sclerostin and glucose homeostasis : No association in healthy men. Cross-sectional and prospective data from the EGIR-RISC study
Introduction: Sclerostin, an inhibitor of bone formation, has emerged as a potential negative regulator of glucose homeostasis. We aimed to investigate if serum sclerostin associates with insulin sensitivity, beta cell function, prediabetes or metabolic syndrome in healthy men. Materials and methods: Serum sclerostin was measured in basal and insulin-stimulated samples from 526 men without diabete
Investigation of evaporating sprays in a medium speed marine engine
The understanding of diesel sprays is very important to enable a better and cleaner marine engine design, but unfortunately little knowledge is openly available on marine engine fuel sprays. In this paper, evaporating sprays for medium speed marine engines were studied in a constant volume combustion chamber by performing optical measurements through Schlieren and Mie diagnostic techniques. The ef
Human experimental exposure to glyphosate and biomonitoring of young Swedish adults
Glyphosate (GLY), N-(phosphonomethyl) glycine, is the most widely used herbicide in the world. It is a broad-spectrum herbicide, also used in crop desiccation. Agricultural workers may be occupationally exposed and general populations may be exposed to GLY mainly through diet. We studied the kinetics of GLY by measuring the parent compound and its metabolite aminomethylphosphonic acid (AMPA) in ur
Using collective intelligence to enhance demand flexibility and climate resilience in urban areas
Collective intelligence (CI) is a form of distributed intelligence that emerges in collaborative problem solving and decision making. This work investigates the potentials of CI in demand side management (DSM) in urban areas. CI is used to control the energy performance of representative groups of buildings in Stockholm, aiming to increase the demand flexibility and climate resilience in the urban
Addressing harms of screening – A review of outcomes in Cochrane reviews and suggestions for next steps
Objective: To investigate if Cochrane reviews that assess screening interventions address their major harms. Study design and setting: A systematic search for Cochrane reviews that assess screening interventions was performed. Two authors independently screened abstracts, assessed full-texts, and extracted data from included reviews. For each review, two authors judged whether each predefined harm
Circulating bioactive adrenomedullin as a marker of sepsis, septic shock and critical illness
Background: Biomarkers can be of help to understand critical illness and to identify and stratify sepsis. Adrenomedullin is a vasoactive hormone, with reported prognostic and potentially therapeutic value in sepsis. The primary aim of this study was to investigate the association of circulating bioactive adrenomedullin (bio-ADM) levels at intensive care unit (ICU) admission with mortality in sepsi
In adults with obesity, copeptin is linked with BMI but is not associated with long-term exposure to cortisol and cortisone
Context: Obesity and cardiometabolic diseases are associated with higher long-term glucocorticoid levels, measured as scalp hair cortisol (HairF) and cortisone (HairE). Cardiometabolic diseases have also been associated with copeptin, a stable surrogate marker for the arginine-vasopressin (AVP) system. Since AVP is, together with corticotropin-releasing hormone (CRH) an important regulator of the
Exploring mediators of the recovery process over time among mental health service users, using a mixed model regression analysis based on cluster RCT data
Background: Personal recovery is associated with many significant health-related factors, but studies exploring associations between activity factors and personal recovery among service users are scarce. The aims of this study were hence to; 1) investigate if various aspects of activity may mediate change in recovery while also acknowledging clinical, sociodemographic and well-being factors; 2) ex
Long sequence single-exposure videography using spatially modulated illumination
Frequency recognition algorithm for multiple exposures (FRAME) is a single-exposure imaging technique that can be used for ultrafast videography, achieved through rapid illumination with spatially modulated laser pulses. To date, both the limit in sequence length as well as the relation between sequence length and image quality are unknown for FRAME imaging. Investigating these questions requires
A circular RNA generated from an intron of the insulin gene controls insulin secretion
Fine-tuning of insulin release from pancreatic β-cells is essential to maintain blood glucose homeostasis. Here, we report that insulin secretion is regulated by a circular RNA containing the lariat sequence of the second intron of the insulin gene. Silencing of this intronic circular RNA in pancreatic islets leads to a decrease in the expression of key components of the secretory machinery of β-c
On boundary confinements for the Coulomb gas
We introduce a family of boundary confinements for Coulomb gas ensembles, and study them in the two-dimensional determinantal case of random normal matrices. The family interpolates between the free boundary and hard edge cases, which have been well studied in various random matrix theories. The confinement can also be relaxed beyond the free boundary to produce ensembles with fuzzier boundaries,
When a foreign gene meets its native counterpart : computational biophysics analysis of two PgiC loci in the grass Festuca ovina
Duplicative horizontal gene transfer may bring two previously separated homologous genes together, which may raise questions about the interplay between the gene products. One such gene pair is the “native” PgiC1 and “foreign” PgiC2 in the perennial grass Festuca ovina. Both PgiC1 and PgiC2 encode cytosolic phosphoglucose isomerase, a dimeric enzyme whose proper binding is functionally essential.
A new efficient method to detect genetic interactions for lung cancer GWAS
Background: Genome-wide association studies (GWAS) have proven successful in predicting genetic risk of disease using single-locus models; however, identifying single nucleotide polymorphism (SNP) interactions at the genome-wide scale is limited due to computational and statistical challenges. We addressed the computational burden encountered when detecting SNP interactions for survival analysis,
A study of tactical and sexual dimorphism in cognition with insights for sexual conflict
The sexes may have different optima in cognitive traits due to differences in life history strategies and the expense of investing in metabolically costly brain tissue. However, given genetic correlations, each sex could be constrained from reaching its cognitive optimum due to intralocus sexual conflict. We compared learning performance of two male alternative reproductive tactics and females fro
Voluntarism promises of proximity as articulated by changing moral elites
The article analyzes the varied meanings historically associated with concepts of voluntarism in relation to social relief as they were articulated by changing moral elites in Denmark from the late nineteenth century until the present. Concepts of voluntarism have historically constituted “normative counterconcepts” that link voluntary practices to desired futures in opposition to alternative mode
Genome-wide association study of self-reported walking pace suggests beneficial effects of brisk walking on health and survival
Walking is a simple form of exercise, widely promoted for its health benefits. Self-reported walking pace has been associated with a range of cardiorespiratory and cancer outcomes, and is a strong predictor of mortality. Here we perform a genome-wide association study of self-reported walking pace in 450,967 European ancestry UK Biobank participants. We identify 70 independent associated loci (P <
Genetic profiling of Vietnamese population from large-scale genomic analysis of non-invasive prenatal testing data
The under-representation of several ethnic groups in existing genetic databases and studies have undermined our understanding of the genetic variations and associated traits or diseases in many populations. Cost and technology limitations remain the challenges in performing large-scale genome sequencing projects in many developing countries, including Vietnam. As one of the most rapidly adopted ge
