Vi lever i en tid av snabb vetenskaplig och teknologisk utveckling. För 100 år sedan hade ingen kunnat drömma om de saker som helt har förändrat vår var- dag och hur vi uppfattar omvärlden; datorer, mobiltelefoner, Internet, rymdfart, våra upptäckter om universums barndom och avlägsna galaxer samt vår insyn i kvantfenomenens mikroskopiska värld. Idag står vi på tröskeln till en era formad av nanotWe live in a time of rapid scientific and technological advancement. People liv- ing 100 years ago could never dream of inventions like those having completely changed our way of life, and our perception of the world; computers, mobile phones, the Internet, space travel, unraveling the mysteries of the early universe and distant galaxies, and our insight into the microscopic world of quantum phe-

Stefan Larsson’s Conceptions in the Code makes a significant contribution to sociolegal analysis and also represents a valuable contribution to conceptual metaphor theory. By utilising the case of copyright in a digital context it explains the role that metaphor plays when the law is dealing with technological change, displaying both conceptual path-dependence as well as what is called non-legislaStefan Larsson's Conceptions in the Code contributes invaluably to socio-legal analysis and conceptual metaphor theory. By examining cases of digital copyright, Larsson elucidates the role that metaphor plays when law is accommodating technological change, displaying both conceptual path-dependence as well as non-legislative developments in law. Analyses draw from conceptual studies of property sp

INTRODUCTION: Merkel cell carcinoma is a rare malignant cutaneous neoplasm that is locally invasive and frequently metastasizes to lymph nodes, liver, lungs, bone and brain. The incidence of Merkel cell carcinoma has increased in the past three decades.CASE PRESENTATION: A 65-year-old Caucasian man presented with a sudden onset of severe headache and a three-month history of balance disturbance. M

We investigate suitable conditions for a C0-semigroup (T(t))t≥0 of Hilbert space contractions to be unitarily equivalent to the restriction of the adjoint shift semigroup (S∗γ(t))t≥0 to an invariant subspace of the standard weighted Bergman space Aγ−2(C+,K). It turns out that (T(t))t≥0 admits a model by (S∗γ(t))t≥0 if and only if its cogenerator is γ-hypercontractive and limt→0T(t)=0 in strong ope

Members of the myocardin family bind to the transcription factor serum response factor (SRF) and act as coactivators controlling genes of relevance for myogenic differentiation and motile function. Binding of SRF to DNA is mediated by genetic elements called CArG boxes, found often but not exclusively in muscle and growth controlling genes. Studies aimed at defining the full spectrum of these CArG

Phenotypic modulation of smooth muscle cells (SMCs) plays a key role in vascular disease, including atherosclerosis. Several transcription factors have been suggested to regulate phenotypic modulation of SMCs but the decisive mechanisms remain unknown. Recent reports suggest that specific microRNAs (miRNAs) are involved in SMC differentiation and vascular disease but the global role of miRNAs in p

OBJECTIVE: Regulation of vascular smooth muscle (VSM) proliferation and contractile differentiation is an important factor in vascular development and subsequent cardiovascular diseases. Recently, microRNAs (miRNAs) have been shown to regulate fundamental cellular processes in a number of cell types, but the integrated role of miRNAs in VSM in blood vessels is unknown. Here, we investigated the ro

Despite recent advances in understanding store-operated calcium entry (SOCE) regulation, the fundamental question of how ER morphology affects this process remains unanswered. Here we show that the loss of RTN4, is sufficient to alter ER morphology and severely compromise SOCE. Mechanistically, we show this to be the result of defective STIM1-Orai1 coupling because of loss of ER tubulation and red

In this study, we present integrated quantitative proteome, transcriptome, and methylome analyses of hematopoietic stem cells (HSCs) and four multipotent progenitor (MPP) populations. From the characterization of more than 6,000 proteins, 27,000 transcripts, and 15,000 differentially methylated regions (DMRs), we identified coordinated changes associated with early differentiation steps. DMRs show

Infections are associated with extensive platelet consumption, representing a high risk for health. However, the mechanism coordinating the rapid regeneration of the platelet pool during such stress conditions remains unclear. Here, we report that the phenotypic hematopoietic stem cell (HSC) compartment contains stem-like megakaryocyte-committed progenitors (SL-MkPs), a cell population that shares

Regulatory T cells (Tregs) differentiate in the thymus, but the mechanisms that control this process are not fully understood. We generated a comprehensive quantitative and differential proteome of murine Tregs and conventional T cells. We identified 5225 proteins, 164 of which were differentially expressed in Tregs. Together with the comparative analysis of proteome and gene expression data, we i

Hematopoietic stem cells possess lifelong self-renewal activity and generate multipotent progenitors that differentiate into lineage-committed and subsequently mature cells. We present a comparative transcriptome analysis of ex vivo isolated mouse multipotent hematopoietic stem/progenitor cells (Lin(neg)SCA-1(+)c-KIT(+)) and myeloid committed precursors (Lin(neg)SCA-1(neg)c-KIT(+)). Our data displ

The field of proteomics is progressing at a rapid pace, developing from primarily a specialist technology to a valuable tool in biological research. Importantly, the establishment of mass spectrometry as a quantitative method, miniaturisation of liquid chromatography techniques, and improved sensitivity of mass-spectrometric instrumentation now enable near-complete monitoring of cellular proteome

Trust within teams is a central performance driver in product innovation. In this paper, we examine the antecedents to and performance implications of trust in firms engaged in radical innovation compared to those working towards incremental innovations. Our findings suggest that systematic processes and structures are significantly linked to trust in firms conducting radical innovation, but not s
