Hospital Admissions for Ischemic Stroke: Does Long-Term Exposure to Air Pollution Interact with Major Risk Factors?

Background: The aim was to investigate whether the effects of major risk factors for ischemic stroke were modified by long-term exposure to air pollution in Scania, southern Sweden. Methods: Cases were defined as first-ever ischemic strokes in patients born between 1923 and 1965 during 2001-2006 (n = 7,244). Data were collected from The Swedish National Stroke Register (Riks-stroke) and the Malmo

The delta C-13 chemostratigraphy of the Upper Ordovician Mjosa Formation at Furuberget near Hamar, southeastern Norway: Baltic, Trans-Atlantic, and Chinese relations

Whereas no studies have previously been carried out on the delta C-13 chemostratigraphy of the Sandbian-Katian (Upper Ordovician) succession anywhere in Norway, such investigations in Sweden and the East Baltic region have made the delta C-13 chemostratigraphy of that interval well known. 1 an attempt to document for the first time the presence of the globally distributed and stratigraphically imp

Proterozoic Basic dykes in the Ukrainian Shield: A palaeomagnetic, geochronologic and geochemical study-The accretion of the Ukrainian Shield to Fennoscandia

A palaeomagnetic, geochronologic and geochemical study of basic dykes in the Ukrainian Shield has been undertaken with the purpose of testing a hypothesis for timing of accretion of the Ukrainian Shield with Fennoscandia. On the basis of geological data it has been suggested that the two shields amalgamated at ca. 1900-1800 Ma. With this study of 11 basic dykes the palaeomagnetic database for the

Adaptive texture space shading for stochastic rendering

When rendering effects such as motion blur and defocus blur, shading can become very expensive if done in a naive way, i.e. shading each visibility sample. To improve performance, previous work often decouple shading from visibility sampling using shader caching algorithms. We present a novel technique for reusing shading in a stochastic rasterizer. Shading is computed hierarchically and sparsely

Direct interaction between cholera toxin and dendritic cells is required for oral adjuvant activity

Cholera toxin (CT) binds to GM1-ganglioside receptors present on all nucleated cells. Despite this, it is a very potent mucosal adjuvant that has a dramatic impact on immune cells, as well as nerve and epithelial cells, causing diarrhea. This fact has hampered our understanding of whether the adjuvanticity of CT is direct or indirect, as cells that bind CT may or may not be involved in its adjuvan

Randomized phase II study of sequential docetaxel and irinotecan with 5-fluorouracil/folinic acid (leucovorin) in patients with advanced gastric cancer: the GATAC trial

Background. The optimal chemotherapy in patients with advanced gastric carcinoma (GC) is yet to be determined. We compared sequential administration of docetaxel and irinotecan, both in combination with infused 5-fluorouracil/leucovorin (5-Fu/Lv), and randomly assigned patients to start with either of the two. Methods. Patients with previously untreated locally advanced or metastatic GC and with m

Computational modelling of oxygenation processes in enzymes and biomimetic model complexes

With computational resources becoming more efficient and more powerful and at the same time cheaper, computational methods have become more and more popular for studies on biochemical and biomimetic systems. Although large efforts from the scientific community have gone into exploring the possibilities of computational methods on large biochemical systems, such studies are not without pitfalls and

Search for Dark Matter in Events with a Hadronically Decaying W or Z Boson and Missing Transverse Momentum in pp Collisions at root s=8 TeV with the ATLAS Detector

A search is presented for dark matter pair production in association with a W or Z boson in pp collisions representing 20.3 fb(-1) of integrated luminosity at root s = 8 TeV using data recorded with the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet with the jet mass consistent with a W or Z boson, and with large missing transverse momentum are analyzed. The data are consi

Educational Homogamy and Gender-Specific Earnings: Sweden, 1990–2009

Abstract in UndeterminedSeveral studies have shown strong educational homogamy in most Western societies, although the trends over time differ across countries. In this article, we study the connection between educational assortative mating and gender-specific earnings in a sample containing the entire Swedish population born 1960-1974; we follow this sample from 1990 to 2009. Our empirical strate

Pre- and perinatal hypoxia associated with hippocampus/amygdala volume in bipolar disorder

Background Pre- and perinatal adversities may increase the risk for schizophrenia and bipolar disorder. Hypoxia-related obstetric complications (OCs) are associated with brain anatomical abnormalities in schizophrenia, but their association with brain anatomy variation in bipolar disorder is unknown. Method Magnetic resonance imaging brain scans, clinical examinations and data from the Medical Bir

Covenants in Venture Capital Contracts

This paper studies how covenants are included in contracts between venture capitalists (VCs) and entrepreneurs. I show that VCs hold covenanted veto rights even though they are shareholders who have access to other powerful governance solutions. Unlike bank loans and bonds, venture capital (VC) contracts exhibit considerable variation in their contractual designs. I exploit this variation to confi

Narrative ability in children with cerebral palsy.

In a previous study a group of children with cerebral palsy (CP) were found to have considerable difficulties with narratives, performing several standard deviations below the criteria for the Information score of the Bus Story Test (BST). To examine in depth the performance of children with CP and a control group with typically developing (TD) children on a narrative task, in order to search for

Socioeconomic Inequalities in Global and Relative Self-Rated Health in Laos: A Cross Sectional Study of 24,162 Men and Women

Abstract in UndeterminedBACKGROUND: . This study examines inequalities in health in Laos. Because perception of health might affect ratings, we used both a global and a relative self-rated health (SRH) question. METHODS: . The study was based on the fourth Lao Expenditure and Consumption Survey, 2007-2008. The study population consisted of 24 162 individuals 20 years or older. Two single-question

No title

Despite the obvious (though as of yet unclear) relationship between economic growth and the persistence of autocratic regimes, there are only few studies that examine how innovation processes affect autocracies - and vice versa. Linking the scholarship on authoritarian consolidation with insights from the National Innovation Systems- and Science and Technology Studies literature, this article argu

Premedication for intubation with morphine causes prolonged depression of electrocortical background activity in preterm infants.

Background:Sedative and analgesic medications are used in critically ill newborns, but little is known about their effects on electrocortical activity in preterm infants. We hypothesized that morphine might induce prolonged neurodepression, independent of blood pressure, compared with rapid sequence induction/intubation (RSI).Methods:Of 34 infants enrolled into a randomized controlled trial (RCT)

Level of education and the risk of lymphoma in the European prospective investigation into cancer and nutrition

Lymphomas belong to the few cancer sites with increasing incidence over past decades, and only a few risk factors have been established. We explored the association between education and the incidence of lymphoma in the prospective EPIC study. Within 3,567,410 person-years of follow-up, 1,319 lymphoma cases [1,253 non-Hodgkin lymphomas (NHL) and 66 Hodgkin lymphomas (HL)] were identified. Cox prop

A Vps21 endocytic module regulates autophagy

In autophagy, the double-membrane autophagosome delivers cellular components for their degradation in the lysosome. The conserved Ypt/Rab GTPases regulate all cellular trafficking pathways, including autophagy. These GTPases function in modules that include guanine-nucleotide exchange factor (GEF) activators and downstream effectors. Rab7 and its yeast homologue, Ypt7, in the context of such a mod
