Nature’s services at risk in a changing climate

Climate change is increasingly posing a threat to biodiversity, both through its direct effects on organisms and through indirect effects resulting from changes in land use. Preserving biodiversity is an ethical obligation, but it is also increasingly being realised that biodiversity contributes to ecosystem services, i.e. ecosystem processes important for human needs and prosperity. In order to a

Consumption of breads containing in situ-produced arabinoxylan oligosaccharides alters gastrointestinal effects in healthy volunteers

Arabinoxylan oligosaccharides (AXOS) are studied as food compounds with prebiotic potential. Here, the impact of consumption of breads with in situ-produced AXOS on intestinal fermentation and overall gastrointestinal characteristics was evaluated in a completely randomized, double-blind, controlled, cross-over study. Twenty-seven healthy volunteers consumed 180 g of wheat/rye bread with or withou

The 21st Century Voice, 1st edition : Contemporary and and Traditional Extra-Normal Voice

The 21st Century Voice is a unified and comprehensive examination of extra-normal vocal production. This work addresses history, science, and religion and documents a wide variety of compositional and performance trends as it explores the seemingly limitless possibilities of the human voice in the 21st Century.Arranged into ten chapters according to the functional components of voice, the text is

Genome editing of human pancreatic beta cell models : problems, possibilities and outlook

Understanding the molecular mechanisms behind beta cell dysfunction is essential for the development of effective and specific approaches for diabetes care and prevention. Physiological human beta cell models are needed for this work. We review the possibilities and limitations of currently available human beta cell models and how they can be dramatically enhanced using genome-editing technologies

Intersectional inequalities and the U.S. opioid crisis: challenging dominant narratives and revealing heterogeneities

Dominant narratives of prescription opioid misuse (POM) in the U.S. have portrayed it as an issue primarily affecting White communities. In this study we explore POM as reported in data from the 2015 National Survey on Drug Use and Health, using an intersectional multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA). We map the risk of POM through a series of multile

People living by changing seas : Mesolithic coastal settlement on the west side of the Baltic Sea

Selected find spots along the Swedish coast of the Baltic Sea are presented, in order to illustrate different ways in which hunter-gatherer societies related to the coast during the Mesolithic. Transformations of the landscape were mainly due to isostatic and eustatic changes. In the northern part, the land rose, forming new coasts and archipelagos at a speed that was noticeable even within one ge

Quality of life of older persons in nursing homes after the implementation of a knowledge-based palliative care intervention

Background: The goals of palliative care are to relieve suffering and promote quality of life. Palliative care for older persons has been less prioritised than palliative care for younger people with cancer, which may lead to unnecessary suffering and decreased quality of life at the final stage of life.Aim: To evaluate whether a palliative care intervention had any influence on the perceived qual

A case study of scaling multiple parameters by the violin

This article will present a single case study of the acoustic attributes of sound production techniques that are involved in the expansion of performance practice with the violin. In this study, four elements were chosen from the multidimensional network involved in playing a normal tone, and then each was intentionally decoupled from ordinario. These elements (bow speed, bow placement, bow angle,

Lojalitetsarbete : Hur visar en advokat lojalitet mot sin klient

I alla vardagliga situationer och relationer gör sig inblandade personers känslor påminda på olika sätt. Det kan få en stor inverkan på utfallet av mänskliga möten i skilda sammanhang. I den ”juridiska världen” har detta länge varit en icke-fråga. Juridiken är till sin natur rationell och objektiv och det gäller juristen också. Så har det sagts. Men detta är av allt att döma en grov förenkling. I

Vitronectin is produced in the lung upon infection by respiratory pathogens, and is utilized to evade the innate immunity

Bacterial extracellular vesicles (EVs) are shed during growth by the respiratory pathogens Pseudomonas aeruginosa and Haemophilus influenzae. Vesicles trigger release of antimicrobial compounds and proteins of the complement, which are partly regulated by vitronectin. We hypothesized that vitronectin is elevated in the lungs during pneumonia, that respiratory epithelial cells produce vitronectin u

Tumor-tracking radiotherapy of moving targets; verification using 3D polymer gel, 2D ion-chamber array and biplanar diode array

The aim of this study was to carry out a dosimetric verification of a dynamic multileaf collimator (DMLC)-based tumor-tracking delivery during respiratory-like motion. The advantage of tumor-tracking radiation delivery is the ability to allow a tighter margin around the target by continuously following and adapting the dose delivery to its motion. However, there are geometric and dosimetric uncert

RapidArc treatment verification using polymer gel dosimetry

The aim of this study was to verify a novel volumetric arc therapy technique, RapidArc". Polymer gel dosimetry system was used to measure the advanced inhomogeneous 3D dose distribution produced using the technique RapidArc". A preclinical installation of the novel beam delivery approach was set up on a linear accelerator at Rigshospitalet in Copenhagen. A prostate treatment plan was delivered to

Kan föräldraförberedelse under graviditeten ge tryggare föräldrar efter förlossningen?

Svensk forskning visar att nyblivna föräldrar önskar att de varit mer förberedda på vad som kommer efter förlossningen men få studier har undersökt hur blivande föräldrar kan förberedas inför den första tiden efter förlossningen. Nu startar ett forskningsprojekt för att utveckla en modell för föräldraförberedelse som ska baseras på föräldrarnas behov.

Maxwell-compensated design of asymmetric gradient waveforms for tensor-valued diffusion encoding.

PURPOSE:Diffusion encoding with asymmetric gradient waveforms is appealing because the asymmetry provides superior efficiency. However, concomitant gradients may cause a residual gradient moment at the end of the waveform, which can cause significant signal error and image artifacts. The purpose of this study was to develop an asymmetric waveform designs for tensor-valued diffusion encoding that i
