Expression of Epstein-Barr Virus-Encoded LMP1 and hTERT Extends the Life Span and Immortalizes Primary Cultures of Nasopharyngeal Epithelial Cells
A 60 000 year Greenland stratigraphic ice core chronology
The Greenland Ice Core Chronology 2005 (GICC05) is a time scale based on annual layer counting of high-resolution records from Greenland ice cores. Whereas the Holocene part of the time scale is based on various records from the DYE-3, the GRIP, and the NorthGRIP ice cores, the glacial part is solely based on NorthGRIP records. Here we present an 18 ka extension of the time scale such that GICC05
Differences in the order of potency for agonists but not antagonists at human and rat adenosine A2A receptors
ADAM12/syndecan-4 signaling promotes beta(1) integrin-dependent cell spreading through protein kinase C alpha and RhoA
The ADAMs (a disintegrin and metalloprotease) comprise a large family of multidomain proteins with cell-binding and metalloprotease activities. The ADAM12 cysteine-rich domain (rADAM12-cys) supports cell attachment using syndecan-4 as a primary cell surface receptor that subsequently triggers beta(1) integrin-dependent cell spreading, stress fiber assembly, and focal adhesion formation. This proce
Synthesis of Conformationally Restricted Oligosaccharides
Gangliosides are sialic acid-containing glycosphingolipids that often are present in increased amounts on tumor cells. Since the gangliosides are hydroxy-acids, they can form lactones. The lactones have been suspected to be more immunogenic than the open forms, but are in practise poor immunogens due to their ease of hydrolysis. This thesis describes the synthesis of the hydrolytically stable lact
U-Pb baddeleyite and zircon ages of 2040 Ma, 1650 Ma and 885 Ma on dolerites in the West African Craton (Anti-Atlas inliers): Possible links to break-up of Precambrian supercontinents
Precambrian inliers of the Anti-Atlas belt in the southern part of Morocco contain numerous dolerite dyke and sill swarms which were previously poorly dated. Four dykes and two sills dated by the U-Pb TIMS method on baddeleyite and zircon provide the first steps toward a magmatic 'barcode' for the West African Craton (WAC) and constraints on the timing of breakup of the WAC from Precambrian superc
Effects of polyamine pool manipulation on genes expressed during the cell cycle
Popular Abstract in Swedish En cell förökar sig genom delning. Före delningen måste den växa och fördubbla cellinnehållet för att det ska finnas material till två nya celler. En cellcykel är de händelser som sker från det en cell delat sig tills den delar sig igen [Fig 1]. En cellcykel kan delas in i fyra faser som cellen måste genomgå innan den är mogen att dela sig. Under första fasen, G1, tillvThe polyamines - putrescine, spermidine and spermine - are polycations found within cells. They have been shown to be essential for optimal cell proliferation and cell survival. Cells maintain their polyamine levels in a well-regulated system involving biosynthesis, catabolism and uptake/excretion. The biosynthetic enzymes - ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase (Ado
SME creation facilitation process at Universities
Much research on SMEs is aimed at researching SMEs after the fact that they have become SMEs. However all SMEs as well as larger companies start as an idea in the head or heads of one or many persons - the prospective entrepreneurs. The purpose of this paper is to investigate how SMEs can be created by transforming ideas into real companies. More specifically we will investigate if and how Univers

The dynamics of industrial influences and consumer behavioural intentions in early phase innovations
This paper aims to synthesise and build further on recent research of consumer behaviour, in order to explain how the industry affects consumer behavioural intentions towards early phase innovations. The rationale for this relies on the non-accessibility of early phase innovations and the implication that they cannot yet be experienced by consumers, which further means they cannot be objectively e
The Technology-Adjusted Balance of Emissions Embodied in Trade: Assessing Global Carbon Emission Displacement from 1995 to 2009
Increasing global production fragmentation allows for emission displacement, which may counteract advanced nation’s domestic reductions of production-related carbon emissions. Consequently, input-output analysis has become a common tool to measure countries’ carbon footprint and emission trade balances based on national consumption instead of domestically produced CO2 emissions. Nevertheless, trad
I valet och kvalet – statssuveränitet eller internationell rättvisa? Internationella brottmålsdomstolens territoriella jurisdiktion över gränsöverskridande brott
I en globaliserad värld står ICC inför svåra utmaningar i fullgörandet av sitt uppdrag att inte lämna de allvarligaste av brott, som angår det internationella samfundet, ostraffade. Stater som inte är parter i Romstadgan har uttalat att domstolen kränker deras statssuveränitet. Särskilt ICC:s agerande gällande deportationen av uigurer till Xinjiang och deportationen av rohingyer från Myanmar till

The Epidemiology of Intracerebral Haemorrahge. Risk factors and prognosis
Preventable breast cancer is postmenopausal
Breast cancer incidence has markedly increased in Western countries for reasons that are not entirely understood. We characterized periodic and age-specific incidence trends of breast cancer in immigrants who migrated from low incidence areas to Sweden. The incidence in immigrants was compared to that in native Swedes and standardized incidence ratios (SIRs) were calculated, based on the Swedish F
Investigation of Climbing Performance at a Country Level
This paper investigates the determinants of Climbing World Cup performance at a country level. An unbalanced panel of 76 countries over the years 2005 through 2008 is used. The focus of the paper is on the impact of the demographic, economic, geographic and historic predictors of the success at the Climbing World Cups. We measure the performance by the National Team rankings for each of the three
Strategic narratives and US military bases in Japan: How ‘deterrence’ makes the Marine base on Okinawa ‘indispensable’
Governed directly by the US from the Battle of Okinawa in 1945 until its reversion to Japan in 1972, the island of Okinawa hosts the majority of US military bases in Japan despite comprising only a fraction of a percent of the total land area. The central government in Tokyo has refused to countenance revision of the status quo in the face of increasing local opposition, including mass protests an
Early Cambrian oxygen minimum zone-like conditions at Chengjiang
The early Cambrian succession at Chengjiang contains the most diverse Cambrian fossil assemblage yet described, and contributes significantly to our understanding of the diversification of metazoans in the Cambrian “explosion”. The Cambrian Period occupies a transitional episode of global ocean chemistry, following the oxygenation of the surface ocean and of shallow marine environments during the
Burgess shale-type biotas were not entirely burrowed away
Burgess Shale-type biotas occur globally in the Cambrian record and offer unparalleled insight into the Cambrian explosion, the initial Phanerozoic radiation of the Metazoa. Deposits bearing exceptionally preserved soft-bodied fossils are unusually common in Cambrian strata; more than 40 are now known. The well-documented decline of soft-bodied preservation following the Middle Cambrian represents
