A crucial role of beta 1 integrins for keratinocyte migration in vitro and during cutaneous wound repair

Integrins are ubiquitous transmembrane receptors that play crucial roles in cell-cell and cell-matrix interactions. In this study, we have determined the effects of the loss of beta1 integrins in keratinocytes in vitro and during cutaneous wound repair. Flow cytometry of cultured beta1-deficient keratinocytes confirmed the absence of beta1 integrins and showed downregulation of alpha6beta4 but not

A parallel integrated model of the Euro50

The Euro50 is an astronomical extremely large telescope for optical and infrared wavelength with a 50 m primary mirror. The telescope will have an elaborate control system ("live optics") to correct for atmospheric and telescope aberrations. To study and predict performance of the complete telescope system, an integrated model combining the structural model of the telescope, optics models, the con

Body Temperature and Activity Rhythms Under Different Photoperiods in High Arctic Svalbard ptarmigan (Lagopus muta hyperborea)

Organisms use circadian rhythms to anticipate and exploit daily environmental oscillations. While circadian rhythms are of clear importance for inhabitants of tropic and temperate latitudes, its role for permanent residents of the polar regions is less well understood. The high Arctic Svalbard ptarmigan shows behavioral rhythmicity in presence of light-dark cycles but is arrhythmic during the pola

Storm-water management in Malmö and Copenhagen with regard to climate change scenarios

Aktuell status för dagvattenhantering i grannstäderna Köpenhamn och Malmö studerades med avseende på befintliga åtgärder och genomförda systemen i de båda städerna. Tillämpning av blå-gröna lösningar i de yttre delarna av Malmö började på 1990-talet och följaktligen är samarbete mellan olika avdelningar inom kommunen mer strukturerat i Malmö medan processen i Köpenhamn fortfarande är baserad på trThe current status of storm-water management in the neighbor cities of Copenhagen and Malmö was studied with respect to present measures and the implemented systems in both cities. Application of blue-green solutions in the outer parts of Malmö started in the 1990s; hence collaboration between different departments in the municipality is more structured in the city of Malmö while in Copenhagen the

Antimicrobial resistance in urinary pathogens among Swedish nursing home residents remains low: a cross-sectional study comparing antimicrobial resistance from 2003 to 2012

Background: There are several risk factors for the colonisation, infection and spreading of antibiotic resistant bacteria among elderly residents of nursing homes. An updated estimate of the native prevalence of antimicrobial resistance in uropathogens among Swedish nursing home residents is needed. Methods: Urine specimens were collected for culture and antimicrobial susceptibility testing agains

Alpha-Synuclein Expression in the Oligodendrocyte Lineage: an In Vitro and In Vivo Study Using Rodent and Human Models.

In this study, we sought evidence for alpha-synuclein (ASYN) expression in oligodendrocytes, as a possible endogenous source of ASYN to explain its presence in glial inclusions found in multiple system atrophy (MSA) and Parkinson's disease (PD). We identified ASYN in oligodendrocyte lineage progenitors isolated from the rodent brain, in oligodendrocytes generated from embryonic stem cells, and in

Sickle cell retinopathy. A focused review

Purpose: To provide a focused review of sickle cell retinopathy in the light of recent advances in the pathogenesis, multimodal retinal imaging, management of the condition, and migration trends, which may lead to increased prevalence of the condition in the Western world. Methods: Non-systematic focused literature review. Results: Sickle retinopathy results from aggregation of abnormal hemoglobin

Tasquinimod triggers an early change in the polarization of tumor associated macrophages in the tumor microenvironment.

Tasquinimod (a quinoline-3-carboxyamide) is a small molecule immunotherapy with demonstrated effects on the tumor microenvironment (TME) involving immunomodulation, anti-angiogenesis and inhibition of metastasis. A target molecule of tasquinimod is the inflammatory protein S100A9 which has been shown to affect the accumulation and function of suppressive myeloid cell subsets in tumors. Given the m

Currency Hedging Management in Global Firms. The case of Heidelberg Cement

Our ever-changing world has to a great extent created a need of efficient financial risk-management programs for financial institutions and corporations operating in a demanding international environment. These changes have however also increased the types of financial tools and derivatives used to handle the multifold macroeconomic exposures. Companies have therefore diversified opportunities to

A Charter Moment: Restructuring Governance for Sustainability

We are living in a highly dynamic, human-dominated Earth System in which non-linear, abrupt and irreversible changes are not only possible but also probable. These changes require institutional structures capable of steering human society away from critical tipping points and irreversible change and ensuring sustainable livelihoods for all. We see 2012 as a charter moment, a historic opportunity t

Numerical investigations of endwall film cooling design of a turbine vane using four-holes pattern

Purpose: Endwall film cooling protects vane endwall by coolant coverage, especially at the leading edge (LE) region and vane-pressure side (PS) junction region. Strong flow impingement and complex vortexaa structures on the vane endwall cause difficulties for coolant flows to cover properly. This work aims at a full-scale arrangement of film cooling holes on the endwall which improves coolant effi

Blood-based mitochondrial respiratory chain function in major depression

Mitochondrial dysfunction has been implicated in major depressive disorder (MDD). A measure of mitochondrial respiratory chain (RC) enzymatic activity—the Mitochondrial Health Index (MHI)—has previously been found to correlate with stress and emotional states in caregivers. We here report mitochondrial RC activities, mitochondrial DNA copy number (mtDNAcn), and the composite MHI in unmedicated and

Seasonal dynamics of haemosporidian (Apicomplexa, Haemosporida) parasites in house sparrows Passer domesticus at four European sites : comparison between lineages and the importance of screening methods

Infectious diseases often vary seasonally in a predictable manner, and seasonality may be responsible for geographical differences in prevalence. In temperate regions, vector-borne parasites such as malaria are expected to evolve lower virulence and a time-varying strategy to invest more in transmission when vectors are available. A previous model of seasonal variation of avian malaria described a

Frame disputes or frame consensus? "environment" or "welfare" first amongst climate strike protesters

Present debates suppose a close linkage between economic, social, and environmental sustainability and suggest that individual wellbeing and living standards need to be understood as directly linked to environmental concerns. Because social movements are often seen as an avant-garde in pushing for change, this article analyzes climate protesters' support for three key frames in current periods of

Geospatial data integration and visualisation using Linked Data

Geospatial data are increasingly available nowadays, and this leads to more analyses and visualisation of geospatial data from several sources. To enable this, we need homogenous data as well as proper integration methods. Geospatial data integration has been a longstanding research topic for decades, and this paper discusses the utilisation of Linked Data technology stack to alleviate the geospat
