Centennial-long trends of lake browning show major effect of afforestation

Observations of increasing water color and organic carbon concentrations in lakes are widespread across the Northern Hemisphere. The drivers of these trends are debated. Declining atmospheric sulfur deposition has been put forward as an important underlying factor, since recovery from acidification enhances mobility of organic matter from surrounding soils. This would suggest that the current brow

Beyond respiration : Controls on lateral carbon fluxes across the terrestrial-aquatic interface

Understanding what controls the lateral flux of organic and inorganic carbon from landscapes to surfacewaters is key to fully understanding terrestrial ecosystem carbon balances, the biogeochemistry of fresh-waters, and how the hydrologically-mediated movement of carbon between these ecosystems may be alteredby global change. In this paper, we synthesize current knowledge and identify major knowled

Exploring the xylose paradox in Saccharomyces cerevisiae through in vivo sugar signalomics of targeted deletants

Background: There have been many successful strategies to implement xylose metabolism in Saccharomyces cerevisiae, but no effort has so far enabled xylose utilization at rates comparable to that of glucose (the preferred sugar of this yeast). Many studies have pointed towards the engineered yeast not sensing that xylose is a fermentable carbon source despite growing and fermenting on it, which is

Early recognition and treatment of neuropsychiatric symptoms to improve quality of life in early Alzheimer's disease : Protocol of the BEAT-IT study

Background: Neuropsychiatric symptoms (NPS) are very common in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) dementia and are associated with various disadvantageous clinical outcomes including a negative impact on quality of life, caregiver burden, and accelerated disease progression. Despite growing evidence of the efficacy of (non)pharmacological interventions to re

Bacterial pseudokinase catalyzes protein polyglutamylation to inhibit the SidE-family ubiquitin ligases

Enzymes with a protein kinase fold transfer phosphate from adenosine 5'-triphosphate (ATP) to substrates in a process known as phosphorylation. Here, we show that the Legionella meta-effector SidJ adopts a protein kinase fold, yet unexpectedly catalyzes protein polyglutamylation. SidJ is activated by host-cell calmodulin to polyglutamylate the SidE family of ubiquitin (Ub) ligases. Crystal structu

Arguments for a Phenomenologically Informed Clinical Approach to Autism Spectrum Disorder

Objective: The aim of this paper is to provide arguments for a phenomenologically informed clinical approach to autism spectrum disorder (ASD), including a plea for clinical attention to the self in ASD. Methods: Central concepts of continental phenomenology, phenomenological psychopathology, and the phenomenological interview are presented, with an emphasis on the potential unifying qualities of

Highly Strained III-V-V Coaxial Nanowire Quantum Wells with Strong Carrier Confinement

Coaxial quantum wells (QWs) are ideal candidates for nanowire (NW) lasers, providing strong carrier confinement and allowing close matching of the cavity mode and gain medium. We report a detailed structural and optical study and the observation of lasing for a mixed group-V GaAsP NW with GaAs QWs. This system offers a number of potential advantages in comparison to previously studied common group

Biological treatment of ankylosing spondylitis : A nationwide study of treatment trajectories on a patient level in clinical practice

Background: There is substantial evidence that patients with ankylosing spondylitis (AS) have high response rates to tumour necrosis factor inhibitors (TNFi), a low likelihood of successful treatment termination, but yet a limited drug retention. Whereas several reports have assessed drug retention rates for TNFi in AS, there are few, if any, studies investigating the actual treatment trajectories

Albumin infusion rate and plasma volume expansion : A randomized clinical trial in postoperative patients after major surgery

Background: Optimal infusion rate of colloids in patients with suspected hypovolemia is unknown, and the primary objective of the present study was to test if plasma volume expansion by 5% albumin is greater if fluid is administered slowly rather than rapidly. Methods: Patients with signs of hypoperfusion after major abdominal surgery were randomized to intravenous infusion of 5% albumin at a dose

Disciplinary discernment : Reading the sky in astronomy education

This theoretical paper introduces a new way to view and characterize learning astronomy. It describes a framework, based on results from empirical data, analyzed through standard qualitative research methodology, in which a theoretical model for a vital competency of learning astronomy is proposed: reading the sky, a broad description under with various skills and competencies are included. This m

The importance of emotional distress, cognitive behavioural factors and pain for life impact at baseline and for outcomes after rehabilitation - A SQRP study of more than 20,000 chronic pain patients

Although literature concerning chronic pain patients indicates that cognitive behavioural variables, specifically acceptance and fear of movement/(re)injury, are related to life impact, the relative roles of these factors in relation to pain characteristics (e.g. intensity and spreading) and emotional distress are unclear. Moreover, how these variables affect rehabilitation outcomes in different s

Transition governance for energy efficiency - Insights from a systematic review of Swedish policy evaluation practices

Background: The transition towards a more sustainable energy system is urgent for addressing global environmental and social challenges, and will require transformative changes including improved energy efficiency in the built environment. To reach identified efficiency potentials, various policy instruments have been introduced but their effects are often unclear. In this paper, we argue that the

Deep Eutectic Solvent Mediated Alkyne-Carbonyl Metathesis (ACM) Reaction for the Synthesis of 2H-Chromene Derivatives

2H-Chromene is an important structural motif present in many biologically active compounds, natural products and showed many other properties. Deep Eutectic Solvent (DES) an environmentally benign and alternative to the conventional organic volatile solvents has been utilized first time for the synthesis of the 2H-chromene derivatives in moderated to excellent yields. The DES is recycled for 5 tim

Positive psychological well-being predicts lower severe pain in the general population : A 2-year follow-up study of the SwePain cohort

Background: Positive psychology indicators like well-being and life satisfaction may play a pivotal role in pain-related outcomes. In this study, we aimed to examine the prospective associations of positive well-being and life satisfaction with pain severity. Methods and Subjects: This longitudinal study, with a follow-up of 2 years, included 9361 participants (4266 males, 5095 females; mean age:

Impact of hip arthroplasty registers on orthopaedic practice and perspectives for the future

□ Total hip arthroplasty (THA) registers are established in several countries to collect data aiming to improve the results after THA. Monitoring of adverse outcomes after THA has focused mainly on revision surgery, but patientreported outcomes have also been investigated. □ Several surgery-related factors influencing the survival of the THA have been thoroughly investigated and have changed clini

Variation in the plasma membrane monoamine transporter (PMAT) (encoded by SLC29A4) and organic cation transporter 1 (OCT1) (encoded by SLC22A1) and gastrointestinal intolerance to metformin in type 2 diabetes : An IMI direct study

OBJECTIVE Gastrointestinal adverse effects occur in 20–30% of patients with metformin-treated type 2 diabetes, leading to premature discontinuation in 5–10% of the cases. Gastrointestinal intolerance may reflect localized high concentrations of metformin in the gut. We hypothesized that reduced transport of metformin via the plasma membrane monoamine transporter (PMAT) and organic cation transport

Time-coded aperture for x-ray imaging

We describe a computational imaging system for x-ray tomography, where image capture and post-processing are co-designed to improve final image quality when relative motion of an experiment’s components during a single exposure causes motion blur. The idea is based on temporally encoding the motion during each exposure by fluttering the detector shutter open and closed with a known sequence for gu

The GALAH survey : A catalogue of carbon-enhanced stars and CEMP candidates

Swan bands-characteristic molecular absorption features of the C2 molecule-are a spectroscopic signature of carbon-enhanced stars. They can also be used to identify carbonenhanced metal-poor (CEMP) stars. The GALAH (GALactic Archaeology with Hermes) is a magnitude-limited survey of stars producing high-resolution, high-signal-to-noise spectra. We used 627 708 GALAH spectra to search for carbon-enh
