Allogeneic lung transplant is limited both by the shortage of available donor lungs and by the lack of suitable long-term lung assist devices to bridge patients to lung transplantation. Avian lungs have different structure and mechanics resulting in more efficient gas exchange than mammalian lungs. Decellularized avian lungs, recellularized with human lung cells, could therefore provide a powerful

Gamma-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the mammalian brain. Once released, it is removed from the extracellular space by cellular uptake catalyzed by GABA transporter proteins. Four GABA transporters (GAT1, GAT2, GAT3 and BGT1) have been identified. Inhibition of the GAT1 by the clinically available anti-epileptic drug tiagabine has been an effective strategy fo

RATIONALE: Idiopathic pulmonary fibrosis (IPF) is a lethal lung disease characterized by lung epithelial cell injury, increased (myo)fibroblast activation and extracellular matrix deposition. Extracellular vesicles (EVs) regulate intercellular communication by carrying a variety of signaling mediators, including WNT proteins. The relevance of EVs in pulmonary fibrosis and their potential contribut

BACKGROUND: Different mechanical ventilation settings are known to affect lung preservation for lung transplantation. Measurement of particle flow in exhaled air may allow online assessment of the impact of ventilation before changes in the tissue can be observed. We hypothesized that by analyzing the particle flow, we could understand the impact of different ventilation parameters.METHODS: Partic

BackgroundThe time taken for epinephrine to achieve its optimal effect during local anesthesia has recently become the subject of debate. The time from injection to commencement of surgery is traditionally quoted to be 7 to 10 min, while recent reports claim that it may take 30 min to achieve maximum hypoperfusion, which would prolong the time required for surgical procedures. The discrepancy may

BackgroundHewes flap is a tarsoconjunctival eyelid flap, based at the lateral canthal tendon, and rotated and stretched to repair lateral defects in the lower eyelid commonly following tumor surgery. The aim of the present study was to monitor perfusion in a Hewes flap during reconstruction, which to the best of our knowledge, has not previously been done.MethodsA Hewes tarsoconjunctival eyelid fl

We will measure kaonic helium X-rays using transition-edge-sensor microcalorimeters, TES, in the J-PARC hadron experimental facility. To demonstrate the feasibility of the experiment, we performed a measurement of pionic carbon X-rays at PSI, where an excellent FWHM energy resolution of 7 eV at 6.4 keV was achieved. We also evaluated the expected TES performance in the kaon beam at J-PARC. The sim

Orkanen Katrina, tsunamin i Indiska oceanen, Lehmankraschen och 11-september attackerna är bara några exempel på sentida händelser som väckt frågor kring vår förmåga att förutse och förstå katastrofrisker. I efterhand är det dock lätt att glömma att vi alltid har ett oändligt antal potentiella scenarier framför oss, men bara ett förflutet, vilket kan få oss att överdriva förutsägbarheten för händeDivision of labor and trade have been prerequisites for the development of welfare societies. Ironically, this specialization has caused a fragmentation of the knowledge necessary to understand risks that may undermine societal safety. This has not only prompted a need for inter-organizational exchange and integration of disaster risk information, it has also prompted a need for understanding how

This thesis makes a contribution to the areas of deregulation, competition and consumer choice. It consists of three self-contained papers. All the research questions are examined in the context of the Swedish motor vehicle inspection market.The first paper, Competition Makes Inspectors More Lenient: Evidence from the Motor Vehicle Inspection Market, investigates whether increased competition moti

Locally Stationary Processes (LSPs) in Silverman’s sense, defined by the modulation in time of a stationary covariance function, are valuable in stochastic modelling of time-varying signals. However, for practical applications, methods to conduct reliable parameter inference from measured data are required. In this paper, we address the lack of suitable methods for estimating the parameters of the

In this study a model was applied on consumer acceptance of commonly implemented EV focused measures. The model is based on a norm-activation process as defined in the Value-Belief-Norm theory and the Norm-Activation Model. The study was based on a questionnaire survey study on three groups of car owners; conventional fossil fuel vehicle owners (CV, n = 312, owners of vehicles run on alternative f

The tumor microenvironment consists of several interacting cell types. Cancer research focssed mainly on the malignant cell in the past. The importance of the tumor microenvironment is increasingly appreciated, as endothelial cells and immune cells were identified as targets for anti-tumor therapy. Targeted therapy against cancer-associated fibroblasts (CAFs) are not in clinical use for the treatm
