Birthweight, BMI in adulthood and latent autoimmune diabetes in adults : a Mendelian randomisation study

Aims/hypothesis: Observational studies have found an increased risk of latent autoimmune diabetes in adults (LADA) associated with low birthweight and adult overweight/obese status. We aimed to investigate whether these associations are causal, using a two-sample Mendelian randomisation (MR) design. In addition, we compared results for LADA and type 2 diabetes. Methods: We identified 43 SNPs actin

Development and evaluation of a method for tumor growth simulation in virtual clinical trials of breast cancer screening

Purpose: Image-based analysis of breast tumor growth rate may optimize breast cancer screening and diagnosis by suggesting optimal screening intervals and guide the clinical discussion regarding personalized screening based on tumor aggressiveness. Simulation-based virtual clinical trials (VCTs) can be used to evaluate and optimize medical imaging systems and design clinical trials. This study aim

DynSus : Dynamic sustainability assessment in groundwater remediation practice

Decision-making processes for clean-up of contaminated sites are often highly complex and inherently uncertain. It depends not only on hydrological and biogeochemical site variability, but also on the associated health, environmental, economic, and social impacts of taking, or not taking, action. These variabilities suggest that a dynamic framework is required for promoting sustainable remediation

Estimating the SARS-CoV-2 infected population fraction and the infection-to-fatality ratio: A data-driven case study based on Swedish time series data

We demonstrate that finite impulse response (FIR) models can be applied to analyze the time evolution of an epidemic with its impact on deaths and healthcare strain. Using time series data for COVID-19-related cases, ICU admissions and deaths from Sweden, the FIR model gives a consistent epidemiological trajectory for a simple delta filter function. This results in a consistent scaling between the

Winter fleshy-fruited plants are the catalysts for spring populations of an invasive fruit fly

Winter is a critical bottleneck period for many insects and is particularly pivotal for pest species, being a major regulator of their populations. In winter, insect fruit pests such as the invasive fly, Drosophila suzukii, not only have to cope with harsh environmental conditions but also need to find alternative resources when cultivated fruit are scarce. This study aimed to disentangle the rela

Measurements of ventilation airflow from pivot and side hung opened windows

HVAC systems have the purpose of improving indoor air quality in buildings to enhance appropriate occupants- comfort, health and good productivity. Window airing may be one measure to consider in the absence of occupant control of the ventilation and by that, we mean occupants opening windows and doors. Approximating the volume of air exchanged during window airing is important in understanding th

microGLYMPH : a conceptual translational roadmap for microdialysis‑based assessment of CSF-interstitial solute exchange in acquired brain injury

The glymphatic system facilitates cerebrospinal fluid (CSF)-interstitial fluid exchange and plays a key role in solute clearance and neurophysiological homeostasis. While dysfunction of this system has been shown in traumatic brain injury, stroke, meningitis, idiopathic normal pressure hydrocephalus and neurodegenerative diseases, direct measurement of glymphatic transport in humans remains elusiv

All-cause and cause-specific mortality in social anxiety disorder : a matched cohort and sibling cohort study

Aims Social anxiety disorder (SAD) is one of the most common anxiety disorders and is associated with significant impairment and societal costs. The association between SAD and mortality remains poorly understood, partly because in epidemiological research it is rarely studied independently from other anxiety disorders. In this population-based matched cohort and sibling control study, we estimate

Esophageal perforation in South of Sweden: Results of surgical treatment in 125 consecutive patients

Background: For many years there has been a debate as to which is the method of choice in treating patients with esophageal perforation. The literature consists mainly of small case series. Strategies for aiding patients struck with this disease is changing as new and less traumatic treatment options are developing. We studied a relatively large consecutive material of esophageal perforations in a

Robotic Assembly and Contact Force Control

Modern industrial robots are traditionally programmed to follow desired trajectories, with the only feedback coming from the internal position/angle sensors in the joints. The robots are in general very accurate in tracking the desired motion, and they have become indispensable in many applications, such as spot welding and painting in the automotive industry. In more complex tasks, such as physic

Physical activity and its effect on bone in the short- and long- term perspective.

Popular Abstract in Swedish Benskörhet (osteoporos), är ett komplext, multifaktoriellt tillstånd som utvecklas i det tysta fram till den dag man drabbas av en fraktur. De senaste 40 åren har antalet benskörhetsfrakturer ökat och i dag beräknas varannan kvinna och var fjärde man någon gång drabbas av en eller flera osteoporosrelaterade frakturer. Exempel på sådana benbrott är frakturer i kota, höftOsteoporosis is a growing problem worldwide where Sweden has one of the highest fragility fracture incidences in the world. The growing years are thought to be an opportune time to build strong bones and the enhancement of peak bone mass (PBM) has been suggested as a prevention strategy for osteoporosis. Most exercise intervention studies in children, evaluating the accrual of areal bone mineral d

Partitioning of nitrate uptake between trees and understory in oak forests

The nitrate reductase activity (NRA) was measured during spring, early summer and late summer in three deciduous forests, where the tree layer was dominated by oak. The nitrate assimilation capacities of the compartments of the above-ground and below-ground biomass of the understory and of the leaves and roots of the tree layer were calculated as NRA per unit biomass and NRA per unit area. The NRA

Efficient Immortalization of Primary Nasopharyngeal Epithelial Cells for EBV Infection Study

Nasopharyngeal carcinoma (NPC) is common among southern Chinese including the ethnic Cantonese population living in Hong Kong. Epstein-Barr virus (EBV) infection is detected in all undifferentiated type of NPC in this endemic region. Establishment of stable and latent EBV infection in premalignant nasopharyngeal epithelial cells is an early event in NPC development and may contribute to its pathog

Genetic Markers of Insulin Sensitivity and Insulin Secretion Are Associated With Spontaneous Postnatal Growth and Response to Growth Hormone Treatment in Short SGA Children: the North European SGA Study (NESGAS)

Purpose: The wide heterogeneity in the early growth and metabolism of children born small for gestational age (SGA), both before and during GH therapy, may reflect common genetic variations related to insulin secretion or sensitivity. Method: Combined multiallele single nucleotide polymorphism scores with known associations with insulin sensitivity or insulin secretion were analyzed for their rela

Willy Brandt och Berlinfrågan : En studie i kontinuiteten i Brandts politiska tänkande

Popular Abstract in Swedish Detta är en studie om Willy Brandt och Berlinfrågan. Berlinfrågan kom att symbolisera en stor del av Brandts politiska gärning och med den som utgångspunkt belyses och analyseras hans politiska livsverk. Med hjälp av en semantisk metod undersöker författaren hur Brandts politiska språk är uppbyggt och redovisar hur hans argumentation ser ut. Tyngdpunkten i studien är enWilly Brandt is one of the most important charismatic leaders of the postwar era and his Ostpolitik is considered his great political achievement. The Berlin Question can be said to symbolize his political activities. Therefore, by concentrating on this issue I can explore and analyse his political thinking as a whole. My basic assumption in this dissertation is that a politician tends to stick to

Metallation of the transition-state inhibitor N-methyl mesoporphyrin by ferrochelatase: Implications for the catalytic reaction mechanism

Insertion of metals into various tetrapyrroles is catalysed by a group of enzymes called chelatases, e.g. nickel, cobalt, magnesium and ferrochelatase. It has been proposed that catalytic metallation includes distorting the porphyrin substrate by the enzyme towards a transition state-like geometry in which at least one of the pyrrole rings will be available for metal chelation. Here, we present a

On Observer-Based Control of Nonlinear Systems

Filtering and reconstruction of signals play a fundamental role in modern signal processing, telecommunications, and control theory and are used in numerous applications. The feedback principle is an important concept in control theory. Many different control strategies are based on the assumption that all internal states of the control object are available for feedback. In most cases, however, o

Uncompensated blood loss is not tolerated during acute normovolemic hemodilution in anesthetized pigs

Clinically, hemodilution to a hematocrit of 9% has been studied, but the effects of hypovolemia during this degree of hemodilution have not been elucidated. We studied the response to blood loss during extreme hemodilution and evaluated indicators of hypovolemia. Systemic and myocardial hemodynamics, oxygen transport, and blood lactate concentrations were measured in 12 anesthetized pigs exposed t

Inhibition of cyclooxygenase-2 enhances immunotherapy against experimental brain tumors.

Glioblastoma multiforme is the most common and aggressive malignant brain tumor in humans, and the prognosis is very poor despite conventional therapy. Immunotherapy represents a novel treatment approach, but the effect is often weakened by release of immune-suppressive molecules such as prostaglandins. In the current study, we investigated the effect of immunotherapy with irradiated interferon-γ
