Post-translational modification of cyclin A1 is associated with staurosporine and TNFalpha induced apoptosis in leukemic cells.

Understanding of molecular mechanisms underlying the effects of cell cycle proteins in response to the chemotherapeutic agents is of great importance for improving the efficacy of targeted therapeutics and overcoming resistance to chemotherapeutic agents. Staurosporine and tumor necrosis factor alpha (TNFalpha) are the therapeutic agents that inhibit tumor cell growth by inducing cell death. Staur

Implementing Web 2.0 Design Patterns in an Institutional Repository May Increase Community Participation

Abstract in UndeterminedObjective – To investigate whether Web 2.0 can enhance participation in institutional repositories (IRs) and whether its widespread use can lead to success in this context. Another purpose was to emphasize how an IR with a Web 2.0 approach can connect individuals in their creative and intellectual outputs, no matter what form of shared material is contributed.Design – Compa

Pollen productivity estimates of key European plant taxa for quantitative reconstruction of past vegetation - a review

Information on the spatial distribution of past vegetation on local, regional and global scales is increasingly used within climate modelling, nature conservancy and archaeology. It is possible to obtain such information from fossil pollen records in lakes and bogs using the landscape reconstruction algorithm (LRA) and its two models, REVEALS and LOVE. These models assume that reliable pollen prod

The relationship between reduced renal function and cardiovascular disease

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Kardiovaskulär sjukdom (CVD) är ett i vårt samhälle växande problem där allt fler insjuknar i akuta hjärtinfarkter, stroke eller hjärtsvikt. Överlevnaden efter insjuknandet har förbättrats med åren med hjälp av nya mediciner och invasiva ingrepp såsom stentning av kranskärlen vid svår kärlkramp och direkt i det akuta skedet vid vissa tThis thesis examines the relationship between measures of renal function and cardiovascular disease (CVD) in patients with hypertension (the NORDIL study) and in the healthy population (Malmö Diet and Cancer Study, MDC) and whether antihypertensive treatment response and the risk of CVD is affected by genetic variation of a regulator of the renal amiloroide sensitive sodium channel (NORDIL). In st

Functional evolution of a multigene family: Orthologous and paralogous pheromone receptor genes in the Turnip Moth, Agrotis segetum

Lepidopteran pheromone receptors (PRs), for which orthologies are evident among closely related species, provide an intriguing example of gene family evolution in terms of how new functions may arise. However, only a limited number of PRs have been functionally characterized so far and thus evolutionary scenarios suffer from elements of speculation. In this study we investigated the turnip moth Ag

Governing the Balance between Sustainability and Competitiveness in Urban Planning: the Case of the Orestad Model

Urban development politics are being challenged in various ways today, which becomes obvious when analysing strategies for sustainability versus competitiveness. In parallel to this, alternative ways of fi nancing, planning and organizing urban development and transport projects are becoming more common. However, although the use of publicly owned enterprises in urban development is becoming more

Haptoglobin Binding Stabilizes Hemoglobin Ferryl Iron and the Globin Radical on Tyrosine beta 145

Aim: Hemoglobin (Hb) becomes toxic when released from the erythrocyte. The acute phase protein haptoglobin (Hp) binds avidly to Hb and decreases oxidative damage to Hb itself and to the surrounding proteins and lipids. However, the molecular mechanism underpinning Hp protection is to date unclear. The aim of this study was to use electron paramagnetic resonance (EPR) spectroscopy, stopped flow opt

Techno-economic evaluation of a two-step biological process for hydrogen production.

An integrated biological process for the production of hydrogen based on thermophilic and photo-heterotrophic fermentation was evaluated from a technical and economic standpoint. Besides the two fermentation steps the process also includes pretreatment of the raw material (potato steam peels) and purification of hydrogen using amine absorption. The study aimed neither at determining the absolute c

Democracy beyond the nation state? Transnational actors and global governance

This is an outline of a new joint Lund-Stockholm six-year research program funded by the Riksbankens Jubileumsfond, addressing three themes: (1) transnational actors and the democratization of international institutions, (2) democracy and public-private partnerships in global governance, and (3) the democratic credentials of transnational actors.

High-k dielectrics on (100) and (110) n-InAs: Physical and electrical characterizations

Two high-k dielectric materials (Al2O3 and HfO2) were deposited on n-type (100) and (110) InAs surface orientations to investigate physical properties of the oxide/semiconductor interfaces and the interface trap density (D-it). X-ray photoelectron spectroscopy analyses (XPS) for native oxides of (100) and (110) as-grown n-InAs epi wafers show an increase in As-oxide on the (100) surface and an inc

The cerebellar microcircuit as an adaptive filter: experimental and computational evidence

Initial investigations of the cerebellar microcircuit inspired the Marr-Albus theoretical framework of cerebellar function. We review recent developments in the experimental understanding of cerebellar microcircuit characteristics and in the computational analysis of Marr-Albus models. We conclude that many Marr-Albus models are in effect adaptive filters, and that evidence for symmetrical long-te

On the complexity of column generation in survivable network design with path-based survivability mechanisms

This survey concerns optimization problems arising in the design of survivable communication networks. It turns out that such problems can be modeled in a natural way as non-compact linear programming formulations based on multicommodity flow network models. These non-compact formulations involve an exponential number of path flow variables, and therefore require column generation to be solved to

Flux analysis of the Lactobacillus reuteri propanediol-utilization pathway for production of 3-hydroxypropionaldehyde, 3-hydroxypropionic acid and 1,3-propanediol from glycerol

Background Lactobacillus reuteri converts glycerol to 3-hydroxypropionic acid (3HP) and 1,3-propanediol (1,3PDO) via 3-hydroxypropionaldehyde (3HPA) as an intermediate using enzymes encoded in its propanediol-utilization (pdu) operon. Since 3HP, 1,3PDO and 3HPA are important building blocks for the bio-based chemical industry, L. reuteri can be an attractive candidate for their production. However

Coastal cliffs on islands as foraging habitat for bats

Small islands usually show simplified ecosystems with limited availability of suitable foraging habitats for bats, thus habitat selection on islands may differ compared to the mainland. Habitats that are marginal on the mainland may be important on islands. The island of Capri consists, to a large extent, of steep limestone cliffs and Mediterranean shrubland, with virtually no forests or other hab

Autoignition of Dimethyl Ether and Air in an Optical Flow-Reactor

Autoignition of dimethyl ether in air was studied in a turbulent flow-reactor with optical access, at conditions relevant to micro gas turbine combustors. The ignition process was visualized using OH*-chemiluminescence imaging, showing the formation of multiple autoignition kernels along the central axis of the reactor. Ignition delays in the range of tau = 112-310 ms were measured at temperatures
