Archaea and the origin of eukaryotes

Woese and Fox's 1977 paper on the discovery of the Archaea triggered a revolution in the field of evolutionary biology by showing that life was divided into not only prokaryotes and eukaryotes. Rather, they revealed that prokaryotes comprise two distinct types of organisms, the Bacteria and the Archaea. In subsequent years, molecular phylogenetic analyses indicated that eukaryotes and the Archaea

Income tax progressivity and inflation during the world wars

This paper studies the impact of inflation on income taxes in Sweden, the UK, and the United States during the world wars. As tax reforms were rising top marginal rates and reducing exemption thresholds, extraordinary levels of inflation eroded the real value of exemptions, brackets, and deductions. The micro-simulation of actual and alternative scenarios shows that inflation made the tax less pro

Accessibility and quality of drug company disclosures of payments to healthcare professionals and organisations in 37 countries: A European policy review

Objectives: To examine the accessibility and quality of drug company payment data in Europe.Design: Comparative policy review of payment data in countries with different regulatory approaches to disclosure.Setting; 37 European countries.Participants: European Federation of Pharmaceutical Industries and Associations, its trade group and their drug company members; eurosfordocs.eu, an independent da

Improving Machine Learning 30-Day Mortality Prediction by Discounting Surprising Deaths

BACKGROUND: Machine learning (ML) is an emerging tool for predicting need of end-of-life discussion and palliative care, by using mortality as a proxy. But deaths, unforeseen by emergency physicians at time of the emergency department (ED) visit, might have a weaker association with the ED visit.OBJECTIVES: To develop an ML algorithm that predicts unsurprising deaths within 30 days after ED discha

A renewable lignin-derived bio-oil for boosting the oxidation stability of biodiesel

The valorisation of lignin is being increasingly recognised to improve the economics of pulp and paper making mills. In the present study, an integrated lignin–glycerol valorisation strategy is introduced with an overarching aim for enhancing the process value chains. LignoBoost kraft lignin was subjected to base-catalysed depolymerisation using glycerol as a co-solvent. The generated bio-oil was

Rapid Separation of Human Hemoglobin on a Large Scale From Non-clarified Bacterial Cell Homogenates Using Molecularly Imprinted Composite Cryogels

The production of a macroporous hydrogel column, known as cryogel, has been scaled up (up to 150 mL) in this work for the purification of human hemoglobin from non-clarified bacterial homogenates. Composite cryogels were synthesized in the presence of adult hemoglobin (HbA) to form a molecularly imprinted polymer (MIP)network where the affinity sites for the targeted molecule were placed directly

Cryogels with affinity ligands as tools in protein purification

Affinity chromatography is one of the well-known separation techniques especially if high purity is desired. Introducing ligands on monolithic structure gives the possibility for purifying complex media such as plasma and crude extract. This chapter is focusing on the preparation of cryogels as monolithic column and immobilization of concanavalin A on its surface as ligand for capturing the glycop

Knee and hip osteoarthritis and risk of nine cancers in a large real-world matched cohort study

ObjectivesJoint replacement due to end-stage OA has been linked to incidence of several cancers. We aimed to estimate the association between newly diagnosed knee and hip OA and incidence of nine common cancer types.MethodsWe identified persons with incident knee or hip OA, aged ≥40 years, between 2009 and 2015 in the SIDIAP database in Catalonia, Spain. We matched up to three OA-free controls on

FAD-Linked Autofluorescence and Chemically-Evoked Zinc Changes at Hippocampal Mossy Fiber-CA3 Synapses

Glutamatergic vesicles in hippocampal mossy fiber presynaptic boutons release zinc, which plays a modulatory role in synaptic activity and LTP. In this work, a fluorescence microscopy technique and the fluorescent probe for cytosolic zinc, Newport Green (NG), were applied, in a combined study of autofluorescence and zinc changes at the hippocampal mossy fiber-CA3 synaptic system. In particular, th

Beyond Urban Sketching: Ethnographic Drawing as a Visual Analytical Method

In this article I have chosen a contemporary phenomenon, urban sketching, as an empirical starting point. Through active participation as an urban sketcher through digital publishing, dialogue and interaction, I analyze my analytical process and urban sketching practice. The aim is to examine ethnographic drawing as a visual cultural analytical method. My contribution is based the connection betwe

Do patient-reported outcome measures correlate with clinical follow-up after arthroscopic treatment of internal derangement of the temporomandibular joint?

INTRODUCTION: Arthroscopic treatment of the temporomandibular joint (TMJ) has traditionally been evaluated with clinical measurements. Additional recordings of patient reported outcome measures (PROM) is expected to make the evaluation more complete. The aim of the study was to evaluate if PROM correlates with clinical follow-up measures after arthroscopic treatment of internal derangement of the

Treatment outcomes and patient-reported quality of life after orthognathic surgery with computer-assisted 2- or 3-dimensional planning : A randomized double-blind active-controlled clinical trial

INTRODUCTION: Thorough treatment planning is essential for a good clinical outcome in orthognathic treatment. The planning is often digital. Both 2-dimensional (2D) and 3-dimensional (3D) software options are available. The aim of this randomized 2-arm parallel double-blinded active-controlled clinical trial was to compare the outcomes of computer-based 2D and 3D planning techniques according to p

Treatment outcome in orthognathic surgery - A prospective comparison of accuracy in computer assisted two and three-dimensional prediction techniques

The main objective of the present study was to assess the accuracy of two- and three-dimensional prediction techniques in orthognathic surgery. It was also a test of the very planning sequence. The scientific question was how well does the software support the surgeon in his way to find the perfect correction of the facial appearance while normalizing the occlusion? Thirty patients with a class II

Mandibular Access Osteotomy for Tumor Ablation : Could a More Tissue-Preserving Technique Affect Healing Outcome?

PURPOSE: Paramedial mandibulotomy facilitates access for the resection of tumors in the oral and oropharyngeal space; however, severe complications related to surgical techniques and radiotherapy have been reported for this procedure. This study evaluated whether preservation of the periosteum during a mandibulotomy would decrease postoperative complications owing to the increased healing capacity

Implant treatment in combination with lateral augmentation of the alveolar process : a 3-year prospective study

BACKGROUND: In patients in whom the height of the alveolar process is adequate but the crest is too narrow to host an implant, lateral augmentation is required. Such augmentations have mostly been performed using autogenous bone blocks secured to the buccal surface. An alternative to autogenous bone may be bovine hydroxyapatite (Bio-Oss, Geistlich Pharma AG, Wolhusen, Switzerland) or other bone su
