Scaffold design remains a main challenge in tissue engineering due to the large number of requirements that need to be met in order to create functional tissues in vivo. Computer simulations of tissue differentiation within scaffolds could serve as a powerful tool in elucidating the design requirements for scaffolds in tissue engineering. In this study, a lattice-based model of a 3D porous scaffol

While high levels of glucose and saturated fatty acids are known to have detrimental effects on beta cell function and survival, the signalling pathways mediating these effects are not entirely known. In a previous study, we found that ADP regulates beta cell insulin secretion and beta cell apoptosis. Using MIN6c4 cells as a model system, we investigated if autocrine/paracrine mechanisms of ADP an

A comprehensive investigation of InAs epitaxy on silicon using template-assisted selective epitaxy is presented. The variation in axial growth rate of InAs nanowires inside oxide nanotube templates is studied as function of nanotube diameter (20-140 nm), growth time (0-30 min), growth temperature (520-580 °C), V/III ratio (40-160), nanotube spacing (300-2000 nm), and substrate crystal orientation.

III-V nanoscale devices were monolithically integrated on silicon-on-insulator (SOI) substrates by template-assisted selective epitaxy (TASE) using metal organic chemical vapor deposition. Single crystal III-V (InAs, InGaAs, GaAs) nanostructures, such as nanowires, nanostructures containing constrictions, and cross junctions, as well as 3D stacked nanowires were directly obtained by epitaxial fill

High mobility (III-V) materials have long been anticipated to replace Si MOSFETs. But only recently [1] were scaled InAs MOSFETs reported to outperform Si devices. However, high-performing III-V devices are typically fabricated on InP substrates which are not compatible with large-scale chip manufacturing. While various III-V on Si fabrication approaches have been reported to overcome this issue,

In this paper, we introduce ${p -channel InAs-Si tunnel field-effect transistors (TFETs) fabricated using selective epitaxy in nanotube templates. We demonstrate the versatility of this approach, which enables III-V nanowire integration on Si substrates of any crystalline orientation. Electrical characterization of diodes and of TFETs fabricated using this method is presented; the TFETs exhibit a

We report complementary metal-oxide-semiconductor (CMOS)-compatible integration of compound semiconductors on Si substrates. InAs and GaAs nanowires are selectively grown in vertical SiO2 nanotube templates fabricated on Si substrates of varying crystallographic orientations, including nanocrystalline Si. The nanowires investigated are epitaxially grown, single-crystalline, free from threading dis

The monolithic integration of III-V nanowires on silicon by direct epitaxial growth enables new possibilities for the design and fabrication of electronic as well as optoelectronic devices. We demonstrate a new growth technique to directly integrate III-V semiconducting nanowires on silicon using selective area epitaxy within a nanotube template. Thus we achieve small diameter nanowires, controlle

In 2015 Region Skåne was the first county council in Sweden to add adult psychiatry patients to the civic service of patient online access to their EHR (electronic health records). The initial implementation of the service in somatic care had previously raised both questions and resistance amongst the healthcare professionals. It was thus considered important to inform the professionals involved a

The complexity of modern interdisciplinary health care practices, where different specialties work together to solve complex problems, challenges traditional approaches to organizational development and quality improvement. An example of this is surgery. This article describes and evaluates an action-oriented method to facilitate organizational development and innovation at an operating unit, cent

A method for the prevention of thrombotic, embolic and/or hemorrhagic disorders, such as cerebral infarction (stroke) or myocardial infarction, by administering levosimendan or its metabolite (II) or any of their pharmaceutically acceptable salts to a mammal in need of such prevention

UNLABELLED: In contrast to women with relatively asymptomatic endometriosis, women with endometriosis-associated chronic pelvic pain (CPP) exhibit nonpelvic hyperalgesia and decreased gray matter volume in key neural pain processing regions. Although these findings suggest central pain amplification in endometriosis-associated CPP, the underlying changes in brain chemistry and function associated

PURPOSE: Currently, radiologic response of brain tumors is assessed according to the Macdonald criteria 10 weeks from the start of therapy. There exists a critical need to identify nonresponding patients early in the course of their therapy for consideration of alternative treatment strategies. Our study assessed the effectiveness of the parametric response map (PRM) imaging biomarker to provide f

OBJECTIVE: To review the clinical presentation and neuroimaging findings in patients with high clinical suspicion for non-accidental trauma (NAT) of the head, to investigate associations between imaging findings and long-term neurologic outcome in abused children.STUDY DESIGN: A retrospective review of 57 cases of NAT of the head from a single institution was performed. Neuroimaging studies (compu

RATIONALE AND OBJECTIVES: Metabolite peak boundary definition is an important postprocessing step in proton magnetic resonance spectroscopy (1H-MRS). We compare metabolite ratios calculated using three different postprocessing strategies: software-rendered default peak boundaries, manually adjusted peak boundaries and a curve-fitting program. The first two of these methods are commercially availab

This invention relates to determining the three-dimensional structure of the cytosolic domain of phospholamban (PLB) and its active site from NMR data of sufficiently high resolution for the three-dimensional structure determination. The invention also relates to methods for rational drug design enabling the design of phospholamban inhibitors based on using the three-dimensional structure data pro

PURPOSE: To describe and report the neuroradiological findings and clinical features in a patient with familial haemophagocytic lymphohistocytosis (FHL), a rare hereditary immune dysregulation in early childhood characterised by multisystem involvement, including in approximately 30% of cases also the central nervous system (CNS).MATERIAL AND METHODS: Serial brain MR examinations were carried out

A three-dimensional calculation method has been further developed to include two-phase, multi-component gas and heat transport processes. A set of momentum, heat transport and gas species equations have been solved for the whole duct by coupled source terms and variable thermophysical properties. The effects of the electrochemical reactions on the heat generation and mass consumption/generation ha
