Complement C1s deficiency in a male Caucasian patient with systemic lupus erythematosus : a case report

Deficiencies of the early complement components of the classical pathway (CP) are well-documented in association with systemic lupus erythematosus (SLE) or SLE-like syndromes and severe pyogenic infections. Among these, complete C1s deficiency has been reported in nine cases so far. Here, we describe a 34-year-old male patient who presented with severe, recurrent infections since childhood, includ

Preliminary evaluation of an automated autoencoder-UNet pipeline for chemical image segmentation and compression with reference to serial ground truth pathology

The rapid advancement of imaging technologies in pathology has ushered in an era of data-intensive diagnostic workflows, generating large volumes of data that demand sophisticated segmentation and compression techniques. Chemical imaging approaches offer an all-digital objective approach to pathological analysis, though image segmentation is required for efficient computation. Convolutional autoen

Coronary Artery Restenosis in Women by History of Preeclampsia

BACKGROUND: A history of preeclampsia is associated with increased risk of coronary artery disease and experimental evidence suggests that a history of preeclampsia also increases the risk of restenosis. However, the extent to which a history of preeclampsia is associated with risk of restenosis after percutaneous coronary intervention in women is unknown. METHODS AND RESULTS: We included 6065 par

Correspondence between areas causing recall in breast cancer screening and artificial intelligence findings

False positive recall is a major issue in breast cancer screening and the introduction of artificial intelligence (AI) might affect which women who are unnecessarily recalled. We have investigated how an AI system works on false positive recalls at screening and compared with radiologist findings. Two-view digital mammography (DM) examinations from 656 recalled women (136 with screening detected c

Learning insertion of a Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) catheter : Is clinical experience necessary? A prospective trial

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging and potentially life-saving procedure, necessitating qualified operators in an increasing number of centres. The procedure shares technical elements with other vascular access procedures using the Seldinger technique, which is mastered by doctors not only in endovascular specialties but also in trauma surg

The release of a pheromonotropic neuropeptide, PBAN, in the turnip moth Agrotis segetum, exhibits a circadian rhythm

In the female turnip moth, Agrotis segetum, a pheromone biosynthesis activating neuropeptide (PBAN) stimulates sex pheromone biosynthesis which exhibits a daily rhythm. Here we show data supporting a circadian rhythm in PBAN release from the corpora cardiaca, which we propose regulates the endogenous rhythm in sex pheromone biosynthesis. This conclusion is drawn as the observed daily rhythm in PBA

Efficacy and safety of varenicline and bupropion, in combination and alone, for alcohol use disorder : a randomized, double-blind, placebo-controlled multicentre trial

Background: Alcohol use disorder (AUD) is associated with an enormous burden of disease and cost to society. The dopamine deficiency hypothesis posits that negative reinforcement generated by a low brain dopamine state drives ethanol intake. Here, we evaluated the efficacy and safety of combined administration of two dopamine-enhancing drugs, varenicline (a partial nicotinic acetylcholine receptor

Optimization of OSPF routing in IP networks

The Internet is a huge world-wide packet switching network comprised of more than 13,000 distinct subnetworks, referred to as Autonomous Systems (ASs) . They all rely on the Internet Protocol (IP) for transport of packets across the network. And most of them use shortest path routing protocols , such as OSPF or IS-IS, to control the routing of IP packets within an AS. The idea of the routing is ex

The environmental impacts of electronics. Going beyond the walls of semiconductor fabs

The growing complexity of integrated circuits and increasing component density place higher requirements for raw material and clean room standards, which demand significant amounts of energy. In spite of these developments, semiconductor facilities managed to reduce their energy intensity measured per product unit. At the same time, the impact of increasing circuit integration on upstream life cyc

Mastering the integration chaos following frequent M&As: IS integration with SOA technology

The use of service oriented architectures (SOA) is rapidly penetrating contemporary business life based on the promise of scalable and flexible information infrastructures. However the technique is still in it infancy and many questions regarding the consequences of a shift towards this kind of IT architecture still remains unanswered. We approach the relation between SOA and another actual topic,

Performance Modelling and Control of Server Systems using Non-linear Control Theory

All service control nodes, for example SCPs, HLRs, and MSCs, are constructed as a server system with one or more servers that process incoming requests. Since service control nodes are sensitive to overload, admission control mechanisms are often implemented. In this paper, we model and analyse admission control mechanisms for server systems with control theoretic methods. We develop a nonlinear s

Capturing Societal Interdependencies from a Flow perspective – Part II: Application

Societal functions constitute of public and private organisations and companies that provide commodities and services that are vi-tal for the functioning of the modern society. The public are highly dependent on these vital societal services and commodities, such as power supply, health care and education. In this paper we present an application of a method for collecting and structuring data and

Convergence analysis of coupling iterations for the unsteady transmission problem with mixed discretizations

We analyze the convergence rate of the Dirichlet-Neumann iteration for the fully discretized one dimensional unsteady transmission problem. Specifically, we consider the coupling of two linear heat equations on two identical non overlapping intervals. The Laplacian is discretized using finite differences on one interval and finite elements on the other and the implicit Euler method is used for the

Simultaneous native UV fluorescence and absorbance detection for microchip electrophoresis using integrated waveguides

This paper reports simultaneous detection of ultra violet (UV) absorbance and native UV-excited fluorescence in an electrophoresis microchip using UV transparent integrated waveguides. Absorbance detection enables detection of a wide range of analytes. When exposed to UV light, some compounds also exhibit native fluorescence, which is here detected simultaneously. Calibration curves were measured
