Introduction: Vasovagal reflex is the most common type of syncope but its etiology is not fully elucidated. Venous return and cardiac output are key in hemodynamic control. The aim of the study was to assess cardiovascular biomarkers and echocardiographic measures at rest and during hypovolemia in women with and without a history of vasovagal syncope. Methods: Fourteen women (aged 18-30) suffering

Viruses are implicated in autoimmune destruction of pancreatic islet β cells, which results in insulin deficiency and type 1 diabetes (T1D)1-4. Certain enteroviruses can infect β cells in vitro5, have been detected in the pancreatic islets of patients with T1D6 and have shown an association with T1D in meta-analyses4. However, establishing consistency in findings across studies has proven difficul

OBJECTIVE: Identifying maturity-onset diabetes of the young (MODY) in pediatric populations close to diabetes diagnosis is difficult. Misdiagnosis and unnecessary insulin treatment are common. We aimed to identify the discriminatory clinical features at diabetes diagnosis of patients with glucokinase (GCK), hepatocyte nuclear factor-1A (HNF1A), and HNF4A MODY in the pediatric population.RESEARCH D

Exceptionally preserved Mesozoic feathered dinosaur fossils (including birds) are famous, but recognized from only very few localities worldwide, and are especially rare in the Southern Hemisphere. Here we report an assemblage of non-avian and avian dinosaur feathers from an Early Cretaceous polar (around 70°S) environment in what is now southeastern Australia. The recovered remains incorporate sm

Background: Screening that includes digital breast tomosynthesis (DBT) with two-dimensional (2D) synthetic mammography (SM) or standard 2D digital mammography (DM) results in detection of more breast cancers than does screening with DM alone. A decrease in interval breast cancer rates is anticipated but is not reported. Purpose: To compare rates and characteristics of (a) interval breast cancer in

Increases in the size of agricultural fields, the loss of permanent green field edges and other semi-natural habitats have accompanied the intensification of agriculture, and are still ongoing. From a farm economic perspective, an increase in field size increases efficiency mainly due to cost savings. However, recent evidence suggests that increases in field size might lead to the loss of ecosyste

Background: Many patients undergo percutaneous coronary intervention (PCI) without the use of non-invasive stress testing prior to treatment. The aim of this study was to determine the potential added value of guiding revascularization by quantitative assessment of myocardial perfusion prior to intervention. Methods and Results: Thirty-three patients (10 females) with suspected or established CAD

We propose a technique for generating millimeter-wave radar waveforms using edge-triggered pulse generator circuits. By synchronizing the chip rate to the oscillation frequency of a binary control signal, a phase shift is introduced in the generated pulses. This way, the millimeter-wave signal can be phase-modulated without the need of additional circuit elements. We show that high-resolution rada

This paper maps social structure, poverty, wealth and economic inequality in Stockholm from 1650 to 1750. We begin by establishing the social structure, using census data and other sources. To study wealth and poverty, the main sources are a sample from the wealth tax of 1715, and probate inventory samples from 1650, 1700 and 1750. These provide detailed and sometimes surprising insights into the

Fatal fires in residential occupancies show a decreasing trend over time, but are still responsible for takingapproximately 90 lives in Sweden each year. Much is known about the victims, but less is known about how thesedeaths can be prevented. There is research on the effectiveness of different measures, but generally they are populationaverageeffectiveness and, since different groups are known t

Based on data from three surveys of the vascular flora of the province of Scania, southernmost Sweden, conducted 1938–1971, 1987–2006 and 2008–2015, we analyse the change in frequency of individual species and groups of species associated with particular vegetation types. A majority of all species have experienced a change in frequency since 1938, and this turnover has continued in recent decades.

A general framework for determining fundamental bounds in nanophotonics is introduced in this paper. The theory is based on convex optimization of dual problems constructed from operators generated by electromagnetic integral equations. The optimized variable is a contrast current defined within a prescribed region of a given material constitutive relations. Two power conservation constraints anal

Populärvetenskaplig sammanfattningAluminium används för en stor mängd produkter, allt från hus och i fordon till såvardagliga produkter som aluminiumburkar. Det breda användningsområdet beror på aluminiumets höga hållfasthet, lätta vikt och dess goda korrosionsmotståndighet. Korrosionsmotståndet beror på att när aluminium exponeras för luft bildas ett aluminiumoxidskikt på ytan, vilket skyddar aluAbstractIn this thesis, the electrochemical deposition process of Sn into ordered nanoporous anodic aluminium oxide (NP-AAO) have been studied. The deposition process was studied in situ using the X-ray techniques: X-ray diffraction (XRD), Grazing incidence Transmission Small-Angle X-ray Scattering (GTSAXS), X-ray Fluorescence (XRF) and X-ray Absorption Near Edge Structure (XANES) and ex situ usin
