Delamination plays a pivotal role during normal development and cancer. Previous work has demonstrated that delamination and epithelial cell movement within the plane of an epithelium are associated with a change in cellular phenotype. However, how this positional change is linked to differentiation remains unknown. Using the developing mouse pancreas as a model system, we show that β cell delamin

Syftet med detta examensarbete är att pressentera ett antal tekniska lösningar för att förbättra säkerheten och kapaciteten i ställverk 59. Ställverk 59 är den vanligaste ställverkstypen på Trafikverkets järnvägsnät. Grundkonstruktionen är utvecklad på 1950-talet, men ställverkstypen nybyggs fortfarande trots konstruktionens ålder. Ända sedan järnvägen infördes har det funnits behov av att styra t

Popular Abstract in Swedish Oönskade reaktioner efter vaccination och allergenspecifik immunoterapi - Kontaktallergi för aluminium och kliande knutor För att ett vaccinationsprogram ska fungera krävs kontinuerlig uppföljning av vaccinernas säkerhet vad gäller eventuella oönskade reaktioner. Under de senaste 10 till 15 åren har en ökad oro noterats bland allmänhet och profession beträffande oönskadThe aim of the work presented in this thesis was to investigate two different types of adverse reactions, persistent itching nodules and contact allergy to aluminium, after immunization with aluminium-containing vaccines and aluminium-containing allergen extracts used for allergen-specific immunotherapy (ASIT). The first paper describes active parental reporting of adverse events (AEFIs) after a

The extent to which in-situ global mechanical tensioning (GMT) can be used to modify the residual stress state in friction stir (FS) welds is investigated in this article. Residual stress distributions have been determined by synchrotron X-ray and neutron diffraction for four sets of FS welds in high-strength AA7449-W51 and lithium containing AA2199-T8 aerospace aluminum alloys subjected to a syst

Al2O3 and HfO2 high-k oxides deposited by atomic layer deposition have been studied on InAs 100 and 111B surfaces. By using a low-frequency fitting routine, interface defect densities have been extracted. In general, both HfO2 and Al2O3 show similar D-it profiles, with a D-it minimum around 2x10(12) eV(-1)cm(-2).

Under 2012–2014 organiserade VIWAFU, ett nätverk för internationellt och interdisciplinärt forskarsamarbete i Norden och Baltikum, fyra seminarier för master-studenter, doktorander och post-docs. Var och ett av seminarierna hade ett tema, t.ex. VA-branschens reglering och styrning, infrastruktur för dricksvatten, innovativ utveckling inom kommunala vattenfrågor samt vattenhantering Viable Water Management and Governance for Futures (VIWAFU), a professional network for international and interdisciplinary collaboration amongst researchers from the Nordic and Baltic countries, was built for providing and sharing knowledge on water management and governance for future policy and decision making during the years 2012–2014. VIWAFU organized four workshops for MSc stud

Mouse embryonic stem cell (mESC) lines were derived by crossing heterozygous transgenic (tg) mice expressing green fluorescent protein (GFP) under the control of the rat tyrosine hydroxylase (TH) promoter, with homozygous alpha-synuclein (aSYN) mice expressing human mutant SNCAA53T under the control of the mouse Prion promoter (MoPrP), or wildtype (WT) mice. The expression of GFP and human aSYN wa

Parkinson's disease (PD) is a neurodegenerative disease with unknown etiology. Here we show the generation of an induced pluripotent stem cell (iPSC) line, named CSC-40, from dermal fibroblasts obtained from a 59-year-old male patient with a homozygous p.Q456X mutation in the PTEN-induced putative kinase 1 (PINK/PARK6) gene and a confirmed diagnosis of PD, which could be used to model familial PD.

Popular Abstract in Swedish Av de 4278 personer äldre än 75 år som ingick i studien vårdade 18 % (n=783) någon annan person pga. dennes nedsatta hälsa. Urvalet var stratifierat. Svarsfrekvensen var i de olika åldersgrupperna 75-79; 60%, 80-84; 56%, 85-89; 48% and 90+ 42%. Av vårdarna var 58% (n=326) män. 81% av männen var gifta, vilket var fallet för 53% av kvinnorna (p<.001). 85% av männen och 59Older people take a great share of caregiving responsibility already and thus understanding of their strain, coping and satis-faction is required. The aim was to investigate dimensions of caregiving activities among elderly (75+) caregivers and to study the dimensions in relation to health-related quality of life (Paper I). It was also to investigate quality of life in relation to loneliness, care

Wireless access technologies such as UMTS with HSPA extensions, WiMAX, and Flash-OFDM and the convergence towards next generation heterogeneous networks enable the realization of always best connected scenarios. As the resulting heterogeneous networks become easier to access and more reliable to depend on, novel telemedicine services such as vehicular emergency applications emerge. Due to their li

Popular Abstract in Swedish Tre-dimensionell ultraljudsundersökning av livmodertappen (cervix) Syftet med avhandlingen var att utvärdera förändringar i livmodertappen (cervix) med tre-dimensionellt ultraljud och utreda om tre-dimensionellt power Doppler ultraljud kan förutsäga tiden till spontan eller inducerad förlossning hos överburna, gravida kvinnor. Avhandlingen baseras på fem studier: reprThe aim of this thesis was to evaluate cervical physiological changes by three-dimensional (3D) ultrasound during pregnancy and to investigate the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy. The thesis is based on five studies: reproducibility of cervical measurements by 3D power Doppler ultrasound (study I), reference data representativ

Most state-of-the-art natural gas-fired combined cycle (NGCC) plants are triple-pressure reheat cycles with efficiencies close to 60%. However, with carbon capture and storage, the efficiency will be penalized by almost 10% units. To limit the energy consumption for a carbon capture NGCC plant, exhaust gas recirculation (EGR) is necessary. Utilizing EGR increases the CO2 content in the gas turbine

Following dramatic changes in the international security environment, civil defence has reemerged as a central priority of governments, which requires collaboration among many stakeholders across sectors and levels of authority. Conditions for achieving such collaboration is a long-standing topic in different literatures, yet this is still a nascent topic in the study of civil defence and prepared

Introduction Breathlessness limits exercise training intensity in people with chronic lung disease (CLD). Stimulation of the trigeminal nerve via fan-to-face (F2F) therapy (facial airflow) can reduce exertional breathlessness and improve exercise endurance in CLD. This randomised controlled trial tested the hypothesis that adding F2F therapy to an exercise training programme could enhance the bene

Background: Exertional breathlessness is a cardinal symptom of people with chronic airflow limitation (CAL) and can be evaluated using cardiopulmonary exercise testing (CPET). Research Question: Does abnormally high exertional breathlessness in relationship to the rate of oxygen uptake (V′O2) and minute ventilation (V′E) indicate different underlying pathophysiologic mechanisms and clinical charac

Background: Treatment of common bile duct (CBD) stones after Roux-en-Y gastric bypass (RYGB) poses a particular challenge given the altered anatomy and inability to perform a standard endoscopic retrograde cholangiogram (ERC). The optimal treatment strategy for intraoperatively encountered CBD stones in post-RYGB patients has not been established. Objectives: To compare outcomes following laparosc
