Variation of the blood content of the pulmonary vascular bed during a heartbeat can be quantified by pulmonary blood volume variation (PBVV) using magnetic resonance imaging (MRI). The aim was to evaluate if PBVV differs in patients with heart failure compared to healthy controls and investigate the mechanisms behind the PBVV. Forty-six patients and 10 controls underwent MRI. PBVV was calculated f

För hundra år sedan började den katolska tidskriften Credo, föregångaren till dagens Signum, utkomma. Den var på många sätt typisk för sin tid och för de strömningar som då gjorde sig gällande i den katolska världen. I denna artikel analyseras Credo under pionjärtiden de första tolv åren och sätts in i sitt samtida katolska sammanhang.

A recent shift in tourism studies has focused on the emotional, affective, embodied, and performative dimensions of heritage landscape experience. However, such research often struggles to transform theoretical and conceptual discussions into practical and applicable terms that can be effectively implemented by site managers. The concept of presence is therefore proposed to identify emotional and

PURPOSE: Large upper eyelid defects can be repaired by rotational full-thickness lower eyelid flaps. The aim was to measure the blood perfusion in such flaps, and how it is affected by the length of the flaps, and the degree of rotation and stretching.METHODS: Nine patients underwent the Quickert procedure for entropion repair in which a full-thickness eyelid flap of approximate width 0.5 cm and l

Educational attainment is an important social determinant of maternal, newborn, and child health1-3. As a tool for promoting gender equity, it has gained increasing traction in popular media, international aid strategies, and global agenda-setting4-6. The global health agenda is increasingly focused on evidence of precision public health, which illustrates the subnational distribution of disease a

RationaleIn China, a large number of men are being squeezed out of the marriage market due to a shortage of marriageable women. Previous research has largely discussed the consequences of gender imbalances and focused on the behavior of marriage-squeezed men that threatens public safety. No empirical studies explored the impact of the social environment on risky behaviors of marriage-squeezed men.

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

The shells of marine mollusks represent promising metagenomic archives of the past, adding to bones, teeth, hairs, and environmental samples most commonly examined in ancient DNA research. Seminal work has established that DNA recovery from marine mollusks depends on their shell microstructure, preservation and disease state, and that authentic ancient DNA could be retrieved from specimens as old

BACKGROUND: The aim of this study was to evaluate satisfaction and factors associated with satisfaction in elderly undergoing lumbar disc herniation surgery.METHODS: In the national Swedish register for spinal surgery (SweSpine) we identified 2095 patients aged > 65 years (WHO definition of elderly) whom during 2000-2016 had undergone LDH surgery and had pre- and one-year postoperative data (age,

Centrality, Central Location and Central Place – the branching of the discourseThis article is an investigation into two central Swedish concepts in the study of landscapes and urbanization, namely central location (“centralort”) and central place (“centralplats”). The travel of these concepts is followed within geography, history and archaeology, from the 1930s and 40s of Germany to the study of

This randomized trial compared the effects of imagery rescripting against in vivo exposure administered separately during a single session with 27 socially anxious individuals. Previous research shows that imagery rescripting is a promising treatment technique for various disorders including social anxiety, although imagery rescripting and exposure for social anxiety have not yet been compared. So

OBJECTIVE: To characterize the systemic phenotype of primary Sjögren's syndrome at diagnosis by analysing the EULAR-SS disease activity index (ESSDAI) scores.METHODS: The Sjögren Big Data Consortium is an international, multicentre registry based on worldwide data-sharing cooperative merging of pre-existing databases from leading centres in clinical research in Sjögren's syndrome from the five con
