Crystallisation of the Glycyl-tRNA synthetase from thermus thermophilus and initial crystallographic data

The glycyl-tRNA synthetase from Thermus thermophilus is a dimer of molecular mass 115 kDa, which has been crystallised using the vapour diffusion method from 5 to 7% polyethylene glycol 6000, 0.8 to 1.4 M NaCl at protein concentrations of 2 to 8 mg/ml. Nucleation is carried out at 4°C and crystals are subsequently transferred to 15°C to maximise growth. Crystals are truncated rhombohedra measuring

Can trainees safely perform pancreatoenteric anastomosis? A systematic review, meta-analysis, and risk-adjusted analysis of postoperative pancreatic fistula

Background: The complexity of pancreaticoduodenectomy and fear of morbidity, particularly postoperative pancreatic fistula, can be a barrier to surgical trainees gaining operative experience. This meta-analysis sought to compare the postoperative pancreatic fistula rate after pancreatoenteric anastomosis by trainees or established surgeons. Methods: A systematic review of the literature was perfor

The association of mitochondrial DNA copy number with incident mental disorders in women : A population-based follow-up study

BACKGROUND: Available evidence suggests that mitochondrial DNA copy number (mtDNA-CN) may differ among patients with mental disorders compared to the general population. However, whether mtDNA-CN is independently associated with the subsequent incidence of mental disorders remains unclear.MATERIAL AND METHODS: We used droplet digital PCR to measure the absolute mtDNA-CN in DNA samples obtained fro

Plasma proteome changes linked to late phase response after inhaled allergen challenge in asthmatics

Background: A subset of individuals with allergic asthma develops a late phase response (LPR) to inhaled allergens, which is characterized by a prolonged airway obstruction, airway inflammation and airway hyperresponsiveness. The aim of this study was to identify changes in the plasma proteome and circulating hematopoietic progenitor cells associated with the LPR following inhaled allergen challen

Sub-micrometer morphology of human atherosclerotic plaque revealed by synchrotron radiation-based μCT—A comparison with histology

Histology is a long standing and well-established gold standard for pathological characterizations. In recent years however, synchrotron radiation-based micro-computed tomography (SRμCT) has become a tool for extending the imaging of two-dimensional thin sections into three-dimensional imaging of tissue blocks, enabling so-called virtual histology with arbitrary clipping planes, volumetric renderi

Differential gene expression of Plasmodium homocircumflexum (lineage pCOLL4) across two experimentally infected passerine bird species

Plasmodium parasites are present in a wide range of host species, some of which tend to be more susceptible than others, potentially as an outcome of evolved tolerance or resistance. Common starlings seem to cope with malaria infection while common crossbills are more susceptible to the same infections. That raises the question if the parasites rely on the same molecular mechanisms regardless of h

Administration of probiotics to healthy volunteers : effects on reactivity of intestinal mucosa and systemic leukocytes

Background: Oral administration of health-promoting bacteria is increasingly used in clinical practise. These bacteria have anti-inflammatory characteristics and modulate the immune system without major reported side effects. The mechanisms of action are not yet fully defined. Our aim was to study systemic effects of probiotics by measurements of leukocytes as well as local effects on rectal mucos

Standardizing the freeze-thaw preparation of growth factors from platelet lysate

BACKGROUND: Over the past decades, the focus on the regenerative properties of platelets (PLTs) has intensified and many PLT-derived growth factors are readily used in medical settings. A general lack of standardization in the preparation of these growth factors remains, however, and this study therefore examines the dynamics of growth factors throughout the freeze-thaw procedure.STUDY DESIGN AND

Seeds of Transformative Learning: Investigating Past Experiences From Implementing Nature-Based Solutions

Nature-based solutions (NBS) attract a growing interest in research and practice due to their potential to address climate change while improving human health and well-being and safeguarding biodiversity. The integration of the NBS concept in urban governance, however, is still emerging and it faces regulatory, political, financial and cognitive barriers. While the literature acknowledges an incre

"It's off-book!" : Developing Serial Complexity across Media in A Series of Unfortunate Events

The article traces the development of narrative complexity in the book and television versions of Lemony Snicket's A Series of Unfortunate Events. The series has been criticized for its repetitive structure; however, drawing on seriality theory by Umberto Eco, Jason Mittell and Frank Kelleter, I demonstrate how it does move beyond repetition and towards a more complex narrative structure. I point

Viral Delivery of GDNF Promotes Functional Integration of Human Stem Cell Grafts in Parkinson's Disease

Dopaminergic neurons (DAns), generated from human pluripotent stem cells (hPSCs), are capable of functionally integrating following transplantation and have recently advanced to clinical trials for Parkinson's disease (PD). However, pre-clinical studies have highlighted the low proportion of DAns within hPSC-derived grafts and their inferior plasticity compared to fetal tissue. Here, we examined w

Multitaper Spectral Granger Causality with Application to Ssvep

The traditional parametric approach to Granger causality (GC), based on linear vector autoregressive modeling, suffers from difficulties related to the inaccurate modeling of the generative process. These limits can be solved by using nonparametric spectral estimates in the frequency-domain formulation of GC, also known as spectral GC. In a simulation study, we compare the mean square error of the

Synthesis and experimental study of novel double perovskite Ba2NixCo2−xO6 as promising oxygen carrier materials for CO2 capture application

Novel oxygen-deficient double-perovskite type oxide Ba2NixCo2−xO6 was applied to produce O2/CO2 mixed stream gas for oxyfuel combustion application. A series of different Co concentration substituted Ba2NixCo2−xO6 was synthesized by an EDTA-citrate sol-gel combustion method. The oxygen carriers, Ba2Ni0.25Co1.75O6, Ba2Ni0.45Co1.55O6, Ba2Ni0.65Co1.35O6 and Ba2Ni0.85Co1.15O6 were c\characterized by s

#50+ fashion Instagram influencers : cognitive age and aesthetic digital labours

Purpose: This paper demonstrates how #50+ fashion Instagram influencers contribute to the social construction of cognitive age through their aesthetic digital labours. Design/methodology/approach: Non-participative netnography was used in the form of visual and textual analysis of over 300 Instagram posts including images, captions and comments. Findings: Findings reveal how outfit selection, back

Diagnostic Stability of Mild Cognitive Impairment, and Predictors of Reversion to Normal Cognitive Functioning

Objective: Studies that investigate predictive factors for spontaneous recovery (reversion) from mild cognitive impairment (MCI) are only beginning to emerge, and the long-term course of MCI is not properly understood. We aimed to investigate stability of the MCI diagnosis, predictors for reversion, as well as the trajectory of MCI over the course of 12 years. Materials and Methods: Data were draw

Parents and the NSU : Secrecy in National Socialist Youth Work in Denmark, 1932-1945

This article examines the role of secrecy in relations between the NSU, the largest Danish national socialist youth organization, and parents. The NSU struggled to recruit and retain members from Danish families with and without national socialist convictions. By analysing how NSU media and internal correspondence framed parents’ reluctance to join, this article traces the changing functions of NS
