Radiocarbon calibration uncertainties during the last deglaciation : Insights from new floating tree-ring chronologies

Radiocarbon dating is the most commonly used chronological tool in archaeological and environmental sciences dealing with the past 50,000 years, making the radiocarbon calibration curve one of the most important records in paleosciences. For the past 12,560 years, the radiocarbon calibration curve is constrained by high quality tree-ring data. Prior to this, however, its uncertainties increase rap

Ecosystem model analysis of multi-use forestry in a changing climate

The challenge of multi-use forestry is to fulfil a range of economic, ecologic and social goals in a sustainable way, accounting for synergies and trade-offs among the ecosystem services provided. Climate changes add to the complexity via effects on forest ecosystem processes, such as primary production and respiration, and also by adding a new goal on the agenda: the role of forests in climate mi

Data on haplotype-supported immunoglobulin germline gene inference

Data that defines IGHV (immunoglobulin heavy chain variable) germline gene inference using sequences of IgM-encoding transcriptomes obtained by Illumina MiSeq sequencing technology are described. Such inference is used to establish personalized germline gene sets for in-depth antibody repertoire studies and to detect new antibody germline genes from widely available immunoglobulin-encoding transcr

Retinoic Acid Puts Hematopoietic Stem Cells Back To Sleep

Dormant hematopoietic stem cells (dHSCs) display superior serial reconstitution capacity compared to active HSCs, although their role in normal hematopoiesis has not been thoroughly investigated. Recently in Cell, Cabezas-Wallscheid et al. (2017) demonstrate involvement of retinoic acid signaling in murine dHSCs for preservation of the HSC pool.

Demagogues of hate or shepherds of peace? Examining the threat construction processes of warlord democrats in Sierra Leone and Liberia

How are threat images framed and constructed by the so-called warlord democrats (WDs)? Societies that have suffered from large-scale civil wars are commonly permeated by inter-group fear and hate. In these contexts, former military or political leaders of armed groups sometimes become involved in post-war politics. These WDs can act as reconciliation spoilers by making securitising moves, i.e. the

The evolution of host-symbiont dependence

Organisms across the tree of life form symbiotic partnerships with microbes for metabolism, protection and resources. While some hosts evolve extreme dependence on their symbionts, others maintain facultative associations. Explaining this variation is fundamental to understanding when symbiosis can lead to new higher-level individuals, such as during the evolution of the eukaryotic cell. Here we p

SOS2 and ACP1 Loci Identified through Large-Scale Exome Chip Analysis Regulate Kidney Development and Function

Genome-wide association studies have identified >50 common variants associated with kidney function, but these variants do not fully explain the variation in eGFR. We performed a two-stage meta-analysis of associations between genotypes from the Illumina exome array and eGFR on the basis of serum creatinine (eGFRcrea) among participants of European ancestry from the CKDGen Consortium (nStage1: 111

IL-6 and CRP are superior in early differentiation between mild and non-mild acute pancreatitis

Background The revised Atlanta classification on acute pancreatitis (AP) presents distinct criteria for severity categorization. Due to the lack of reliable prognostic markers, a majority of patients with AP are currently hospitalized and initially managed identically. As incidence and financial costs are rising the need for early severity differentiation will increase. This study aimed to investi

Caring for patients with spinal metastasis during an MRI examination

Introduction: Magnetic resonance imaging (MRI) is without question the best tool used for diagnosing and evaluating spinal metastasis. An MRI examination is known to be of great value for the treatment planning and survival of these patients. Radiographers have an important role in how the quality of care is experienced by the patients during an MRI examination. The purpose of the study was to des

Forehearing words : Pre-activation of word endings at word onset

Occurring at rates up to 6-7 syllables per second, speech perception and understanding involves rapid identification of speech sounds and pre-activation of morphemes and words. Using event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI), we investigated the time-course and neural sources of pre-activation of word endings as participants heard the beginning of unfolding wOccurring at rates up to 6-7 syllables per second, speech perception and understanding involves rapid identification of speech sounds and pre-activation of morphemes and words.

C1-inhibitor decreases the release of vasculitis-like chemotactic endothelial microvesicles

The kinin system is activated during vasculitis and may contribute to chronic inflammation. C1-inhibitor is the main inhibitor of the kinin system. In this study, we investigated the presence of the kinin B1 receptor on endothelial microvesicles and its contribution to the inflammatory process. Compared with controls (n=15), patients with acute vasculitis (n=12) had markedly higher levels of circu

Angiogenic and inflammatory biomarkers in the differentiation of pulmonary hypertension

Objectives. Pulmonary hypertension (PH) is a serious condition where diagnosis often is delayed due to unspecific symptoms. New methods to diagnose and differentiate PH earlier would therefore be of great value. The aim of this study was therefore to evaluate the relationship between circulating angiogenic and inflammatory biomarkers and various hemodynamic variables in relation to different cause

Prognostic and predictive importance of the estrogen receptor coactivator AIB1 in a randomized trial comparing adjuvant letrozole and tamoxifen therapy in postmenopausal breast cancer : the Danish cohort of BIG 1-98

Purpose: To evaluate the estrogen receptor coactivator amplified in breast cancer 1 (AIB1) as a prognostic marker, as well as a predictive marker for response to adjuvant tamoxifen and/or aromatase inhibitors, in early estrogen receptor-positive breast cancer. Method: AIB1 was analyzed with immunohistochemistry in tissue microarrays of the Danish subcohort (N = 1396) of the International Breast Ca

Long-Term Outcomes After Distal Scaphoid Fractures : A 10-Year Follow-Up

Purpose: The aim of this study was to evaluate the functional, clinical, and radiological outcome 10 years after distal scaphoid fractures. Methods: From a prospective epidemiological study on posttraumatic radial-sided wrist pain, we evaluated 41 cases of distal scaphoid fractures. All cases had been treated nonsurgically in a thumb spica cast. Patients were examined using radiographs, magnetic r

Bedömning av neurologisk prognos efter hjärtstopp : Uppdaterade rekommendationer från Svenska HLR-rådets expertgrupp

European Resuscitation Council (ERC) issued updated guidelines for postresuscitation care in 2015. This paper provides updated Swedish recommendations for neurological prognostication of patients remaining unconscious after cardiac arrest (CA). The prognostication should be based on independent methods; clinical and neurophysiological examinations, imaging and biomarkers. It should not be performe

Type 2 diabetes, glucose, insulin, BMI, and ischemic stroke subtypes : Mendelian randomization study

Objective: To implement a mendelian randomization (MR) approach to determine whether type 2 diabetes mellitus (T2D), fasting glucose, fasting insulin, and body mass index (BMI) are causally associated with specific ischemic stroke subtypes. Methods: MR estimates of the association between each possible risk factor and ischemic stroke subtypes were calculated with inverse-variance weighted (convent
