Sleep problems, in particular the difficulty in initiating and maintaining sleep are important comorbidities in children and adolescents with attention deficit hyperactivity disorder (ADHD), accompanied by a range of negative consequences for both patients and their caregivers. Melatonin, a naturally occurring hormone that is important for coordinating the body's sleep-wake cycle, has been used to
STUDY QUESTION: Which substances and signal transduction pathways are potentially active downstream to the effect of FSH and LH in the regulation of human oocyte maturation in vivo? SUMMARY ANSWER: The regulation of human oocyte maturation appears to be a multifactorial process in which several different signal transduction pathways are active. WHAT IS KNOWN ALREADY: Many studies in animal species
The European Congenital Heart Surgeons Association (ECHSA) Congenital Database (CD) is the second largest clinical pediatric and congenital cardiac surgical database in the world and the largest in Europe, where various smaller national or regional databases exist. Despite the dramatic increase in interventional cardiology procedures over recent years, only scattered national or regional databases
BACKGROUND: Streptococcus bovis/equinus complex (SBSEC) comprise several species and subspecies and is a common cause of infective endocarditis (IE). S. gallolyticus subsp. gallolyticus (Sg gallolyticus) accounts for a majority of SBSEC IE, but the risk of IE for other subspecies is largely unknown. We aimed to investigate the clinical presentation of bacteraemia, and proportion of patients with I
Despite a large number of studies, out of all drivers of radiative forcing, the effect of aerosols has the largest uncertainty in global climate model radiative forcing estimates. There have been studies of aerosol optical properties in climate models, but the effects of particle number size distribution need a more thorough inspection. We investigated the trends and seasonality of particle number
Hematopoietic stem cells (HSCs) are rare cells on top of the differentiation hierarchy of hematopoiesis. HSCs are unique in their combined capacity to differentiate into all mature blood lineages and self-renew to maintain the HSC pool. Based on classical models of hematopoiesis in mouse, the self-renewal potential of HSCs is gradually and step-wise lost during the transition from long term (LT)-H
The aim of this article is to analyse and critique Greek authorities’ expectations for a ‘credible’ account in queer asylum claims. As some of the caseworkers’ accounts portray, through 16 semi-structured interviews, in order to be deemed ‘credibly queer’ applicants are expected to have passed through a painful, discursively narratable process of self-realization and have suffered enough in their
Deep convolutional neural networks (CNNs) have been shown to predict poverty and development indicators from satellite images with surprising accuracy. This paper presents a first attempt at analyzing the CNNs responses in detail and explaining the basis for the predictions. The CNN model, while trained on relatively low resolution day- and night-time satellite images, is able to outperform human
Purpose We aim to investigate how professionals make sense of the culture in the context of PSFs and how they engage in organizational and professional identification. Methodology The researchers look into the sensemaking processes professionals attach to organizational culture from a symbolic interactionism tradition, while from a critical perspective challenging the mainstream assumptions about
Purpose: This thesis aims to investigate how customers’ pre-existing brand loyalty influences their perceptions of four characteristics – Perceived Usefulness (PU), Perceived Ease of Use (PEoU), Perceived Trustworthiness (PT), and Perceived Human-likeness (PH) – of AI chatbots used in customer service. In turn, we strive to examine how those perceptions affect overall customer satisfaction towards
Background and issue of study: The global financial crisis, climate change, demographic changes, and rising inequality are some of the global trends that put pressure on public leaders and organizations, civil society organizations and corporations to shift to a social and environmental sustainable development. Social innovations are demanded to be both drivers of positive societal change and forc
The ongoing refugee crisis has divided the European Union. While some states shelter hundreds of thousands of refugees, others only grant asylum to a handful. This phenomenon is creating a demographic rift inside the union and is also causing internal quarrels over joint responsibility, which possibly could undermine the existence of the organization. In this thesis we search for the potential cau
Purpose: The purpose of this thesis is to identify and analyze innovative products and services within the telecom industry, letting these findings constitute possible ways for CSPs to innovate the experience of their customers. Methodology: The research in this thesis was conducted from a qualitative approach and data were collected using primary- (expert interviews) and secondary sources (journa
