Preparation and kinetic characterization of a fusion protein of yeast mitochondrial citrate synthase and malate dehydrogenase

We have expressed the DNA of the fusion of CS1 to MDH1 in Escherichia coli gltA-. The fusion protein (CS1/MDH1) is the C-terminus of CS1 linked in-frame to the N-terminus of MDH1 with a short linker of glycyl-seryl-glycyl. The fusion protein produced was isolated and purified. Gel filtration studies indicated that CS1/MDH1 had a M(r) of approximately 170,000. Western blotting analysis with SDS gel

Hur lika är bilisters och cyklisters preferenser? : Resultat från en resvaneundersökning i Lund, Malmö och Helsingborg

För att åstadkomma en förändrad färdmedelsfördelning krävs kunskap om olika gruppers preferenser och deras faktiska beteende. Syftet med denna rapport är att identifiera arbetspendlares preferenser som i förlängningen kan ligga till grund för planering av ökat gående och cyklande. Studien tar sitt avstamp i en webbaserad resvaneundersökning ställd till anställda på Lunds Tekniska Högskola (LTH), M

Modeling Quantum Cascade Lasers : The Challenge of Infra-Red Devices

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-

Conceptions in the Code : How Metaphors Explain Legal Challenges in Digital Times

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

Extensive central nervous system involvement in Merkel cell carcinoma : a case report and review of the literature

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

An Agler-type model theorem for C0-semigroups of Hilbert space contractions

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

Emerging roles of the myocardin family of proteins in lipid and glucose metabolism

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

Smooth muscle miRNAs are critical for post-natal regulation of blood pressure and vascular function

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

MicroRNAs are necessary for vascular smooth muscle growth, differentiation, and function

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
