The association between hormone therapy (estrogen, with or without progesterone) and colorectal cancer (CRC) has received considerable scientific interest but previous research has generated inconsistent results. We aimed to examine whether post-diagnostic use of hormone therapy might protect against CRC mortality and all-cause mortality. Women diagnosed with CRC between January 2007 and December

All echolocating bats and whales measured to date emit a directional bio-sonar beam that affords them a number of advantages over an omni-directional beam, i.e. reduced clutter, increased source level and inherent directional information. In this study, we investigated the importance of directional sound emission for navigation through echolocation by measuring the sonar beam of brown long-eared b

Framkomlighetsåtgärder för bussar i städer kan vara en viktig åtgärd för att förbättra kollektivtrafikens attraktivitet och därmed bidra till en överflyttning av resor från privatbilen till kollektivtrafiken. Många städer runt om i världen genomför framkomlighetsåtgärder och vetenskapliga studier av motiven och incitamenten för att införa sådana åtgärder har genomförts i vissa länder. Men studier

Despite of multitude investigations no reliable prognostic immunohistochemical biomark-ers in GIST have been established so far with added value to predict the recurrence risk of high risk GIST besides mitotic count, primary location and size. In this study, we analyzed the prognostic relevance of eight cell cycle and apoptosis modulators and of TP53 mutations for prognosis in GIST with high risk

This paper presents a direct measurement of the decay width of the top quark using tt¯ events in the lepton+jets final state. The data sample was collected by the ATLAS detector at the LHC in proton–proton collisions at a centre-of-mass energy of 8 TeV and corresponds to an integrated luminosity of 20.2 fb- 1. The decay width of the top quark is measured using a template fit to distributions of ki

BACKGROUND The association between neighborhood deprivation and mortality is well established, but knowledge about whether deprivation is best assessed regionally or nationally is scarce. OBJECTIVE The present study aims to examine whether there is a difference in results when using national and county-specific neighborhood deprivation indices and whether the level of urbanization modifies the ass

The "double Dirac cone" 2D topological interface states found on the (001) faces of topological crystalline insulators such as Pb1-xSnxSe feature degeneracies located away from time reversal invariant momenta and are a manifestation of both mirror symmetry protection and valley interactions. Similar shifted degeneracies in 1D interface states have been highlighted as a potential basis for a topolo

Quantum devices depend on addressable elements, which can be modified separately and in their mutual interaction. Self-assembly at surfaces, for example, formation of a porous (metal-) organic network, provides an ideal way to manufacture arrays of identical quantum boxes, arising in this case from the confinement of the electronic (Shockley) surface state within the pores. We show that the electr

hCAP-18 is the only human member of the antibacterial and endotoxin-binding family of proteins known as cathelicidins. The antibacterial and endotoxin binding domains reside in the C-terminal 37 amino acids of the protein (LL-37) and this is believed to be unleashed from the neutralizing N-terminus by proteases from peroxidase positive granules. In human neutrophils, peroxidase positive and peroxi

This article explores the underlying culture of war sustaining the setting of scenarios within cyberwar games. In particular, it engages with the question of how to simulate a phenomenon that, due to its remoteness, possesses an ambivalent relation to reality. Looking at scenarios of major national and international cyberwar games as illustrations, this article, first, engages with the modes of ex

Rotational coherent anti-Stokes Raman scattering (CARS) is an established diagnostic technique for thermometry and species concentration measurements of di-atomics and tri-atomics in combustion processes; however, studies on hydrocarbon fuel molecules have been scarce. In this work, we have investigated the diagnostic potential for rotational CARS on ethane with emphasis on concentration measureme

Objectives. The aim of this study was to assess the incidence, the prenatal detection rate by ultrasound, and the pregnancy outcome of spina bifida (SB) in Denmark (DK) in 2008-2015 and to compare results to national data from Sweden. Methods. Data were retrieved from the Danish Fetal Medicine Database, which includes International Classification of Diseases-(ICD-) 10 codes for pre-or postnatally

n-type Mg3Sb1.5Bi0.5 has recently been discovered to be a promising thermoelectric material, yet the effective n-type dopants are mainly limited to the chalcogens. This may be attributed to the limited chemical insight into the effects from different n-type dopants. By comparing the effects of different chalcogen dopants Q (Q = S, Se, and Te) on thermoelectric properties, it is found that the chal

Employing lightweight, tool-based code review of code changes (aka modern code review) has become the norm for a wide variety of open-source and industrial systems. In this paper, we make an exploratory investigation of modern code review at Google. Google introduced code review early on and evolved it over the years; our study sheds light on why Google introduced this practice and analyzes its cu

Decomposition of soil organic matter (SOM) in permafrost terrain and the production of greenhouse gases is a key factor for understanding climate change-carbon feedbacks. Previous studies have shown that SOM decomposition is mostly controlled by soil temperature, soil moisture, and carbon-nitrogen ratio (C:N). However, focus has generally been on site-specific processes and little is known about v

Aim: To explore whether high-level endurance training in early age has an influence on the arterial wall properties in young women. Methods: Forty-seven athletes (ATH) and 52 controls (CTR), all 17-25 years of age, were further divided into runners (RUN), whole-body endurance athletes (WBA), sedentary controls (SC) and normally active controls (AC). Two-dimensional ultrasound scanning of the carot

Light-level geolocators are currently widely used to track the migration of small-sized birds, but their potentially detrimental effects on survival of highly aerial species have been poorly investigated so far. We recorded capture–recapture histories of 283 common swifts Apus apus and 107 pallid swifts Apus pallidus breeding in 14 colonies in Italy, Spain, Sweden and Switzerland that were equippe
