Single nucleotide polymorphisms in the 20q13 amplicon genes in relation to breast cancer risk and clinical outcome

The 20q13 region is frequently amplified/overexpressed in breast tumours. However, the nature of this amplification/overexpression is unknown. Here, we investigated genetic variation in five 20q13 amplicon genes (MYBL2, AURKA, ZNF217, STK4 and PTPN1) and its impact on breast cancer (BC) susceptibility and clinical outcome. As a novel finding, four polymorphisms in STK4 (rs6017452, rs7271519) and A

Mild hypothermia markedly reduces ischemia related coronary t-PA release.

In experimentally induced myocardial ischemia, mild hypothermia (33-35 degrees C) has a robust cardioprotective effect. Tissue plasminogen activator (t-PA) is a profibrinolytic enzyme that is released from the vascular endothelial cells in response to ischemia and other injurious stimuli. t-PA has also been found to have proinflammatory properties that could contribute to reperfusion injury. We po

State Policy and Internal Migration - A Study of the Household Registration (hukou) System in China

In China, the past 30 years have been characterized by economic growth and rapid development that has transformed the nation into an important player on the international market. This phenomenal progress probably would have been impossible without the cheap labor force provided by the Chinese countryside in the form of migrant workers. Millions of rural people circulate the nation today in order t

Postgraduate education in internal medicine in Europe

Background: Limited information exists on the framework and content of postgraduate education in internal medicine in Europe. This report describes the results of a survey of postgraduate training in internal medicine in the European countries. Methods: Two online questionnaire-based surveys were carried out by the European Board of Internal Medicine, one on the practice of internists and the othe

Allergic eosinophil-rich inflammation develops in lungs and airways of B cell-deficient mice

Immunoglobulins (Ig), particularly IgE, are believed to be crucially involved in the pathogenesis of asthma and, equally, in allergic models of the disease. To validate this paradigm we examined homozygous mutant C57BL/6 mice, which are B cell deficient, lacking all Ig. Mice were immunized intraperitoneally with 10 micrograms ovalbumin (OVA) plus alum, followed by daily (day 14-20) 30 min exposure

CYP17 genetic variation and risk of breast and prostate cancer from the national Cancer Institute Breast and Prostate Cancer Cohort Consortium (BPC3)

CYP17 encodes cytochrome p450c17 alpha, which mediates activities essential for the production of sex steroids. Common germ line variation in the CYP17 gene has been related to inconsistent results in breast and prostate cancer, with most studies focusing on the nonsynonymous single nucleotide polymorphism (SNP) T27C (rs743572). We comprehensively characterized variation in CYP17 by direct sequenc

Tuberculosis mortality during a civil war in Guinea-Bissau

CONTEXT: Tuberculosis (TB) is an increasing global problem, despite effective drug therapies. Access to TB therapy during conflict situations has not been studied. OBJECTIVE: To determine the effect of irregular TB treatment due to an armed conflict in Guinea-Bissau, West Africa. DESIGN, SETTING, AND PATIENTS: Ongoing retrospective cohort study conducted in the capital city of Bissau among 101 pat

Leaching of hazardous substances from additives and admixtures in concrete

The aim of this work was to study the leaching of hazardous substances in additives and admixtures that are commonly contained in concrete. Time-dependent leaching has been analyzed for three types of metal containing concretes: with ordinary Portland cement (OPC), fly ash, and slag. The concretes had uniform leaching patterns, clearly above detection limits. The prolonged diffusion test of 1,700

A diet based on multiple functional concepts improves cardiometabolic risk parameters in healthy subjects

Background: Different foods can modulate cardiometabolic risk factors in persons already affected by metabolic alterations. The objective of this study was to assess, in healthy overweight individuals, the impact of a diet combining multiple functional concepts on risk markers associated with cardiometabolic diseases (CMD). Methods: Fourty-four healthy women and men (50-73 y.o, BMI 25-33, fasting

Succession in two plots at "Kungsmarken" between 1952 and 2005 with different historical management

Abstract The main influences on growing conditions in pastures and hayfields are grazing and mowing, which regulate the species struggle for space and resources. If the management ceases, this will contribute to a change of the vegetation. A succession starts where the plant cover gradually will change according to a specific pattern. After some time a few competitive species, previously disfavou

Estimation of baseline levels of bacterial community tolerance to Cr, Ni, Pb, and Zn in unpolluted soils, a background for PICT (pollution-induced community tolerance) determination

The PICT method (pollution-induced community tolerance) can be used to assess whether changes in soil microbial response are due to heavy metal toxicity or not. Microbial community tolerance baseline levels can, however, also change due to variations in soil physicochemical properties. Thirty soil samples (0–20 cm), with geochemical baseline concentrations (GBCs) of heavy metals and from five diff

Palaeolithic diet decreases fasting plasma leptin concentrations more than a diabetes diet in patients with type 2 diabetes : A randomised cross-over trial

Background: We have previously shown that a Palaeolithic diet consisting of the typical food groups that our ancestors ate during the Palaeolithic era, improves cardiovascular disease risk factors and glucose control compared to the currently recommended diabetes diet in patients with type 2 diabetes. To elucidate the mechanisms behind these effects, we evaluated fasting plasma concentrations of g

Terpenoid emissions from fully grown east Siberian Larix cajanderi trees

While emissions of many biogenic volatile organic compounds (BVOCs), such as terpenoids, have been studied quite intensively in North American and Scandinavian boreal forests, the vast Siberian boreal forests have remained largely unexplored by experimental emission studies. In this study the shoot-scale terpenoid emission rates from two mature Larix cajanderi trees growing in their natural habita

A novel nutritional supplement containing amino acids and chromium decreases postprandial glucose response in a randomized, double-blind, placebo-controlled study

High postprandial blood glucose levels are associated with increased mortality, cardiovascular events and development of diabetes in the general population. Interventions targeting postprandial glucose have been shown to prevent both cardiovascular events and diabetes. This study evaluates the efficacy and safety of a novel nutritional supplement targeting postprandial glucose excursions in non-di

Five-year results in Ewing's sarcoma. The Scandinavian Sarcoma Group experience with the SSG IX protocol

The first Scandinavian protocol for Ewing's sarcoma, SSG IV, resulted in a local control rate of 74% and 5-year metastasis-free survival (MFS) of 43%. The second protocol, SSG IX, was started in order to improve upon these results. It featured four chemotherapy cycles, each consisting of two courses of VAI (vincristine, doxorubicin, ifosfamide) alternating with one course of PAI (cisplatin, doxoru

Retailising Space, Architecture, Retail and the Territorialisation of Public Space

In recent decades we have witnessed a proliferation of new kinds of retail space. Retail space has cropped up just about everywhere in the urban landscape, at libraries, workplaces, churches and museums. In short, retail is becoming a more and more manifest part of the public domain. The traditional spaces of retail such as city centres and outlying shopping malls are either increasing in size or

On the Machinability of Ductile and Strain Hardening Materials - Models and Methods for Analyzing Machinability

Popular Abstract in Swedish Allteftersom kraven på kvalité och prestanda hos dagens produkter ökar används alltmer avancerade material som en del av modern produktion. Problemet som uppstår är dock att dessa material ställer nya krav på tillverkningsprocessen och då inte minst vid skärande bearbetning. Trots att en betydande mängd forskning redan har publicerats vad gäller skärande bearbetning av As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. Even though a significant amount of research has been published on the machining of these materials knowledge is still limited in several crucial areas. A problem w

Surface energy exchange in pristine and managed boreal peatlands

Surface–atmosphere energy exchange is strongly ecosystem-specific. At the same time, as the energy balance constitutes responses of an ecosystem to environmental stressors including precipitation, humidity and solar radiation, it results in feedbacks of potential importance for the regional climate. Northern peatlands represent a diverse class of ecosystems that cover nearly 6 × 106 km2 in the Bor

Dissolved organic carbon leaching flux in a mixed agriculture and forest watershed in Rwanda

Study region: Rukarara River Watershed (RRW), Rwanda. Study focus: DOC leaching has important environmental consequences for both terrestrial and aquatic ecosystems. This paper measures leached dissolved organic carbon (LDOC) and the factors controlling its variation in the RRW, a mixed agriculture and forest watershed in Rwanda. The study describes the relationship of LDOC with land use/land cove

Population responses of bird populations to climate change on two continents vary with species’ ecological traits but not with direction of change in climate suitability

Climate change is a major global threat to biodiversity with widespread impacts on ecological communities. Evidence for beneficial impacts on populations is perceived to be stronger and more plentiful than that for negative impacts, but few studies have investigated this apparent disparity, or how ecological factors affect population responses to climatic change. We examined the strength of the re
