Multiple rare variants in high-risk pancreatic cancer-related genes may increase risk for pancreatic cancer in a subset of patients with and without germline CDKN2A mutations

The risk of pancreatic cancer (PC) is increased in melanoma-prone families but the causal relationship between germline CDKN2A mutations and PC risk is uncertain, suggesting the existence of non-CDKN2A factors. One genetic possibility involves patients having mutations in multiple high-risk PC-related genes; however, no systematic examination has yet been conducted. We used next-generation sequenc

STAT5 induces miR-21 expression in cutaneous T cell lymphoma

In cutaneous T cell lymphomas (CTCL), miR-21 is aberrantly expressed in skin and peripheral blood and displays anti-apoptotic properties in malignant T cells. It is, however, unclear exactly which cells express miR-21 and what mechanisms regulate miR-21. Here, we demonstrate miR-21 expression in situ in both malignant and reactive lymphocytes as well as stromal cells. qRT-PCR analysis of 47 patien

Outcome of simple decompression of the compressed ulnar nerve at the elbow – influence of smoking, gender, and electrophysiological findings

Background: Compression of the ulnar nerve at elbow is frequently treated with simple decompression. Knowledge about factors influencing results of surgery of the nerve is limited and contradictory. The primary aim was to evaluate outcome of simple decompression of the nerve using a QuickDASH questionnaire, and to investigate any influence of smoking, gender, and preoperative electrophysiological

A developmental model for alcohol use disorders in Swedish men

Background: Alcohol use disorder (AUD) is a classic multifactorial syndrome and it is critical to understand the diversity of the relevant risk factors and how they inter-relate over development. Method: We examined 21 risk factors for AUD in four developmental tiers reflecting (i) birth, (ii) childhood and early adolescence, (iii) late adolescence, and (iv) early adulthood in 47 414 Swedish men o

Concealing or revealing? Alternative paths to profiting from innovation

One stream of research states that closed innovation and knowledge concealing is imperative for firms seeking to profit from innovation. Another stream of research states that firms can enhance innovation outcomes by means of openness and the selective revealing of knowledge. To contrast these two streams of research, we offer a comparative analysis of under what conditions firms should conceal or

Optimising Archaeologic Ceramics h-XRF Analyses

We present the first results of an experiment which is aimed at ultimately producing recommendations for analysing archaeologic ceramics specimens using handheld XRF analysis devices. In this experiment we study the effects of different measurement durations, different number of measured points and three different types of surface treatments (breakage, polished, grounded) when analysing ceramics s

Experiences of security and continuity of care : Patients' and families' narratives about the work of specialized palliative home care teams

Background:: Those who are seriously ill and facing death are often living with physical, emotional, social, and spiritual suffering. Teamwork is considered to be necessary to holistically meet the diverse needs of patients in palliative care. Reviews of studies regarding palliative care team outcomes have concluded that teams provide benefits, especially regarding pain and symptom management. Muc

On the Design of Reduced State Demodulators with Interference Cancellation for Iterative Receivers

We consider the problem of designing demodulators for channels with memory that use reduced-size trellis descriptions for the received signal. We assume an overall iterative receiver, and for the parts of the signal not covered by the trellis description, we use interference cancellation based on the soft information provided by the outer decoder. In order to reach a trellis description, a linear

Sensor Fused Indoor Positioning Using Dual Band WiFi Signal Measurements

In this paper, signal strengths from known WiFi access points are used together with a particle filter to perform indoor navigation. It is shown that more information is obtained by using signals of both 2.4 and 5.0 GHz, compared to using only one frequency. Thus, using both frequencies provides a more accurate positioning. The second contribution is an algorithm where WiFi measurements are combin

Multiple stakeholders and B2B branding in emerging markets

PurposeThe main purpose of this study is to investigate perceptions about and contributing activities to business-to-business (B2B) brand value by corporate managers and local stakeholders in the context of emerging markets.Design/methodology/approachThe case study examines brand strategies of a multinational company in the high-tech industry. By using NVIVO, this research analyses the brand narra

Why distinguish between statistics and mathematical statistics - the case of Swedish academia

A separation between the academic subjects statistics and mathematical statistics has existed in Sweden almost as long as there have been statistics professors. The same distinction has not been maintained in other countries. Why is it kept in Sweden?In May 2015 it has been 100 years since Mathematical Statistics was formally established as an academic discipline at a Swedish university where Stat

Ultra-low Voltage Embedded Memories – Design Aspects and a Biomedical Use-case

As the Internet of Things (IoT) era emerges the need for ultra-low power (ULP) devices is becoming more eminent. A research-proven approach to achieve ULP consumption is to aggressively lower the supply voltage (VDD) below or in the vicinity of the transistor threshold voltage (Vth) and operate the transistors in the subthreshold (sub-Vth) region. Operating below or near the threshold voltage, i.eAs the Internet of Things (IoT) era emerges the need for ultra-low power (ULP) devices is becoming more eminent.

Geographic elevation, car driving, and depression among elderly residents in rural areas : The Shimane CoHRE study

Given that public transportation networks are often worse in rural areas than in urban areas, it is difficult for elderly non-drivers to access health-promoting goods, services, and resources related to mental health. Moreover, geographical location, assessed by elevation, could modify this association in a rural area. The aim of this study was to test whether the association between car driving (

An Improved Stochastic Send-on-Delta Scheme for Event-Based State Estimation

Event-based sensing and communication holds the promise of lower resource utilization and/or better performance for remote state estimation applicationsin e.g networked control systems (NCS). However, the problem of designing an optimal event-based state estimator often becomes untractable due to nonlinear measurements. This complexity is avoided with stochastic event-triggering. In this work, we

Hur förstå "och" i "vetenskap och beprövad erfarenhet"?

”Varje läkare, vare sig han är i allmän tjänst eller enskilt utövar läkaryrket, åligger att i överensstämmelse med vetenskap och beprövad erfarenhet meddela patient de råd och, såvitt möjligt, den behandling, som patientens tillstånd fordrar,”Begreppet vetenskap och beprövad erfarenhet har åtminstone sedan 1800-talet följt svenska läkare, inte minst genom ovanstående bestämmelse i de läkarinstrukt

Magiska möjligheter : Harry Potter, Artemis Fowl och Cirkeln i skolans värdegrundsarbete

Sedan den första Harry Potter-boken publicerades år 1997 har intresset för fantasylitteratur ökat lavinartat. Miljoner av barn, ungdomar och vuxna har följt sina mest omtyckta fantasyhjältar och –hjältinnor på deras äventyr in i magiska världar, där verklighetens lagar utmanas, överskrids och ställs på ända. Men vad kan läsare lära sig om sin egen värld via karaktärernas upptäcksresor in i de magi

High incidence of infective endocarditis in adults with congenital ventricular septal defect

Objective Ventricular septal defects (VSDs), if haemodynamically important, are closed whereas small shunts are left without intervention. The long-term prognosis in congenital VSD is good but patients are still at risk for long-term complications. The aim of this study was to clarify the incidence of infective endocarditis (IE) in adults with VSD. Methods The Swedish registry for congenital heart
