Ectodomain shedding of L1 adhesion molecule promotes cell migration by autocrine binding to integrins.
2001
The L1 adhesion molecule plays an important role in axon guidance and cell migration in the nervous system. L1 is also expressed by many human carcinomas. In addition to cell surface expression, the L1 ectodomain can be released by a metalloproteinase, but the biological function of this process is unknown. Here we demonstrate that membrane-proximal cleavage of L1 can be detected in tumors and in the developing mouse brain. The shedding of L1 involved a disintegrin and metalloproteinase (ADAM)10, as transfection with dominant-negative ADAM10 completely abolishes L1 release. L1-transfected CHO cells (L1-CHO) showed enhanced haptotactic migration on fibronectin and laminin, which was blocked …
Bosnia and Herzegovina: assessing health systems capacity to manage large influx of refugees and migrants. Joint report on a mission of the Health Au…
2020
The large numbers of refugees and migrants arriving in and transiting through Bosnia and Herzegovina pose new challenges to the health system, which must adapt and respond to the needs of both migrants and residents. This requires an efficient policy dialogue between the main stakeholders to share experiences and identify best practices. The WHO Regional Office for Europe, through the Migration and Health programme, supports Member States for strengthening the health sector's capacity to provide evidence-informed responses to the public health challenges for refugee and migrant health. In this regard, a joint assessment mission was carried out in Bosnia and Herzegovina in 2019, using the WH…
Fuel inventory and material migration of JET main chamber plasma facing components compared over three operational periods
2020
Fuel retention and material migration results from JET ITER-like wall beryllium limiter tiles are presented for three operating periods. Ion beam analysis results support the general picture of erosion during limiter configurations with local deposition on tile ends far into the scrape off layer. Similar trends of fuel concentrations are observed in all JET operating periods; (i) low on surfaces exposed to high heat flux and erosion and (ii) higher in deposits. The pattern of fuel retention and deposition correlates with heat flux and distribution of limiter plasmas touching inner and outer limiters. The D/Be ratio in the thickest deposit is similar to 0.01. Global fuel retention attributed…
Refugee and migrant health in Bosnia and Herzegovina: the role of WHO in complex political environments
2019
Nowadays, refugees and migrants are the focus of intense political debate worldwide. From the public health perspective, population movement, including forced migration, is a complex phenomenon and is a high priority on the political and policy agenda of most WHO Member States. Health diplomacy and the health of refugees and migrants are intrinsically linked. Human mobility is relevant to all countries and creates important challenges in terms of both sustainable development and human rights, to ensure equality and achieve results through the Sustainable Development Goals. This book is part of the WHO Regional Office for Europe’s commitment to work for the health of refugees and migrants. I…

Borrelia burgdorferi sensu lato in Ixodes ricinus ticks collected from migratory birds in Southern Norway
2010
Abstract Background Borrelia burgdorferi sensu lato (s.l.) are the causative agent for Lyme borreliosis (LB), the most common tick-borne disease in the northern hemisphere. Birds are considered important in the global dispersal of ticks and tick-borne pathogens through their migration. The present study is the first description of B. burgdorferi prevalence and genotypes in Ixodes ricinus ticks feeding on birds during spring and autumn migration in Norway. Methods 6538 migratory birds were captured and examined for ticks at Lista Bird Observatory during the spring and the autumn migration in 2008. 822 immature I. ricinus ticks were collected from 215 infested birds. Ticks were investigated f…
Migration Techniques in HPC Environments
2014
Process migration is an important feature in modern computing centers as it allows for a more efficient use and maintenance of hardware. Especially in virtualized infrastructures it is successfully exploited by schemes for load balancing and energy efficiency. One can divide the tools and techniques into three groups: Process-level migration, virtual machine migration, and container-based migration.

In Vitro Evaluation of the Biological Effects of ACTIVA Kids BioACTIVE Restorative, Ionolux, and Riva Light Cure on Human Dental Pulp Stem Cells
2019
This study aimed to analyze the biological effects of three new bioactive materials on cell survival, migration, morphology, and attachment in vitro. ACTIVA Kids BioACTIVE Restorative (Pulpdent, Watertown, MA, USA) (Activa), Ionolux (Voco, Cuxhaven, Germany), and Riva Light Cure UV (SDI, Bayswater, Australia) (Riva) were handled and conditioned with a serum-free culture medium. Stem cells from human dental pulp (hDPSCs) were exposed to material extracts, and metabolic activity, cell migration, and cell morphology were evaluated. Cell adhesion to the different materials was analyzed by scanning electron microscopy (SEM). The chemical composition of the materials was evaluated by energy-dispe…
