There are excellent guidelines for clinicians to manage venous diseases but few reviews to assess their hemodynamic background. Hemodynamic concepts that evolved in the past have largely remained unchallenged in recent decades, perhaps due to their often complicated nature and in part due to emergence of new diagnostic techniques. Duplex ultrasound scanning and other imaging techniques which evolv

Background: The need for anticoagulation therapy (AC) in patients with subsegmental pulmonary embolism (SSPE) diagnosed by computed tomography of the pulmonary arteries (CTPA) has been questioned, as these patients run low risk for recurrent venous thromboembolism (VTE) during 3 months of follow-up. Whether this applies also to patients with small PE diagnosed with pulmonary scintigraphy has not y

This study focusses on the hydrogeology of Urema Graben, especially possible interactions between surface water and groundwater around Lake Urema, in Gorongosa National Park (GNP). Lake Urema is the only permanent water source for wildlife inside GNP, and there are concerns that it will disappear due to interferences in surface-water/groundwater interactions as a result of changes in the hydraulic

Background: Copeptin is a reliable surrogate marker for the neurohypophyseal hormone vasopressin. Elevated plasma level of copeptin has been associated with cardiovascular and metabolic disease risk. Objective: To investigate the association between copeptin and risk of dementia. Methods: In all, 18,240 individuals from Malmö, Sweden, were examined between 2002 and 2006 (mean age 69.3 years, 69.8

The automatic detection and classification of stance taking in text data using natural language processing and machine learning methods create an opportunity to gain insight about the writers’ feelings and attitudes towards their own and other people’s utterances. However, this task presents multiple challenges related to the training data collection as well as the actual classifier training. In o

Urban environments are expanding rapidly, and with urbanization come both challenges and opportunities for wildlife. Challenges include combating the anthropogenic disturbances such as light, noise and air pollution and lower availability of natural food sources. The benefits are many, including the availability of anthropogenic food sources, breeding boxes and warmer temperatures. Thus, depending

We manipulate the information subjects can share on the web concerning socially sensitive actions (public good contribution) and visibility (selfie) to determine the effect on social image, as captured by the price subjects demand for publication. The overall conclusion from the experiment is that theory about social reputation can predict subjects' social-signaling behavior. People take costly de

To address banks’ risk taking during the recent financial crisis, we develop a model of credit-portfolio optimization and study the impact of risk-based capital regulation (Basel Accords) on banks’ asset allocations. The model shows that, when a bank’s capital is constrained by regulation, regulatory cost (risk weightings in the Basel Accords) alters the risk and value calculations for the bank’s

We examine the moral hazard effects of bank recapitalizations by assessing the impact of the U.S. TARP program on market discipline exerted by subordinated debt-holders using a sample of 123 bank holding companies over the period 2004-2013. Predicted distress risk has a consistently positive and significant effect on sub-debt spreads, suggesting the presence of market discipline. A higher bailout

This chapter focuses on business models and the role of internal standardization in business models. We develop a typology that outlines the role of internal standardization for a set of value configurations that serve as representations of generic business models. The topic is of importance for both managers and researchers in relation to firm level innovation and strategy, as well as how busines

Insufficient tissue oxygenation, or hypoxia, contributes to tumor aggressiveness and has a profound impact on clinical outcomes in cancer patients. At decreased oxygen tensions, hypoxia-inducible factors (HIFs) 1 and 2 are stabilized and mediate a hypoxic response, primarily by acting as transcription factors. HIFs exert differential effects on tumor growth and affect important cancer hallmarks in

OBJECTIVES: The aim of this study was twofold: (i) to evaluate the air levels of N-nitrosamines in the Swedish rubber industry and (ii) to estimate the risk of symptoms and changed levels of immunologic markers in relation to these levels.METHODS: Using adsorption tubes, we collected samples of N-nitrosamines in the breathing zone of 96 rubber workers and analyzed them with liquid chromatography t

A century after its inception, agroecology has entered mainstream development debates as a more sustainable alternative to conventional agricultural modernization of relevance not least for improving smallholder agriculture in sub-Saharan Africa. Agroecology is a broad concept considered to have transformative potential, yet as a research field it has often been technology-centred and focused at t

This contribution analyses the presence of Economic History in the undergraduate study programmes of some European countries. The objective is to offer a counterpoint to the Spanish experience, which will be addressed by other papers and is also likely the most known framework for most of the participants. We look at the total offer of Economic History courses, as well as at whether they are only

Aims and objectives: To investigate lung recipients' process of transition from prior the transplantation to one year afterwards, as well as what their main concerns are and how they deal with these concerns. Background: During the last three decades, lung transplantation has been established as an effective treatment for patients with end-stage pulmonary disease. Towards the end of the 20th centu
