Phosphorylation of ERα and HIF-1α in breast cancer with focus on tamoxifen response and links to kinase activation

Anti-oestrogens are commonly used in adjuvant breast cancer treatment and for a long time tamoxifen has been the main endocrine treatment. Patients who are eligibly for endocrine treatment are selected by the tumour-specific expression of oestrogen receptor (ER) and approximately 70 % of all breast cancer patients are classified as ER positive. However, resistance to tamoxifen is common and severa

Inverse relation between vitamin D and serum total immunoglobulin G in the Scandinavian Cystic Fibrosis Nutritional Study

Background/Objectives: The hallmark of cystic fibrosis (CF) is chronic lung inflammation. The severity of lung disease is closely correlated with immunoglobulin G (IgG) levels. Beyond its contribution to the bone health, the importance of vitamin D has not been fully recognized owing to the lack of human studies providing evidence of its benefit. In the context of the recently described immunomodu

Inotropic Support During Experimental Endotoxemic Shock: Part II. A Comparison of Levosimendan with Dobutamine

BACKGROUND: We compared the association of levosimendan or dobutamine with norepinephrine for the maintenance of systemic and hepatosplanchnic perfusion during early endotoxemic shock. METHODS: Twenty anesthetized pigs (26.8 +/- 0.5 kg) were instrumented with flow probes and catheters to monitor systemic and regional perfusion as described in our companion article in this issue of the journal. Two

Resonant photoemission spectroscopy studies of the magnetic phase transitions in Pr0.5Sr0.5MnO3

The valence band electronic structure of Pr0.5Sr0.5MnO3 has been investigated using resonant photoemission spectroscopies across its paramagnetic metallic (PMM)-ferromagnetic metallic (FMM)-antiferromagnetic insulator (AFMI) transition. Using bulk sensitive soft X-ray photoemission, we have confirmed the presence of a gap in the near Fermi level electronic spectrum in the charge ordering (CO) anti

The very long-term course of severe depression, with focus on suicidality

Abstract Objective: To study the very long-term course of severe depression and the subjects own experiences many years after a suicide attempt. Method: Patients diagnosed with severe depression/melancholia between 1956 and 1969 were interviewed 37- 53 years after index admission. Seventy-five telephone interviews were held and medical records were read in many cases. Long-term course of depressio

Myocardial infarction in relation to mercury and fatty acids from fish: a risk-benefit analysis based on pooled Finnish and Swedish data in men

Background: Exposure to methylmercury from fish has been associated with increased risk of myocardial infarction (MI) in some studies. At the same time, marine n-3 (omega-3) PUFAs are an inherent constituent of fish and are regarded as beneficial. To our knowledge, no risk-benefit model on the basis of data on methylmercury, PUFA, and MI risk has yet been presented. Objective: The objective of thi

PSA-based screening for prostate cancer: How does it compare with other cancer screening tests?

Context: Despite the substantive societal impact of prostate cancer, the medical community is currently divided on the balance between benefit and harm of screening for prostate cancer using prostate-specific antigen (PSA). Objective: To examine whether PSA-based screening for prostate cancer meets current guidelines on efficacy and effectiveness for screening, and how it compares with other curre

Economic effects of introducing alternative Salmonella control strategies in Sweden

The objective of the study was to analyse the economic effects of introducing alternative Salmonella control strategies in Sweden. Current control strategies in Denmark and the Netherlands were used as benchmarks. The true number of human Salmonella cases was estimated by reconstructing the reporting pyramids for the various scenarios. Costs were calculated for expected changes in human morbidity

Turning weakness into strength: strategies for future LIS

Purpose – LIS has been described as a fragmented field in crisis, with an increased competition from other fields; and lacking in development of theories. The purpose of this paper is to articulate a strategy in which the perceived weakness can be seen as a source of strength. Design/methodology/approach – The text builds mostly on reflections on meta-theoretical and science-organisation literatur

Plant macrofossil evidence for an early onset of the Holocene summer thermal maximum in northernmost Europe.

Holocene summer temperature reconstructions from northern Europe based on sedimentary pollen records suggest an onset of peak summer warmth around 9,000 years ago. However, pollen-based temperature reconstructions are largely driven by changes in the proportions of tree taxa, and thus the early-Holocene warming signal may be delayed due to the geographical disequilibrium between climate and tree p

Increases in terrestrially derived carbon stimulate organic carbon processing and CO2 emissions in boreal aquatic ecosystems

The concentrations of terrestrially derived dissolved organic carbon have been increasing throughout northern aquatic ecosystems in recent decades, but whether these shifts have an impact on aquatic carbon emissions at the continental scale depends on the potential for this terrestrial carbon to be converted into carbon dioxide. Here, via the analysis of hundreds of boreal lakes, rivers and wetlan

Adsorption and incorporation of transition metals at the magnetite Fe3O4(001) surface

The adsorption of Ni, Co, Mn, Ti, and Zr at the (root 2 x root 2)R45 degrees-reconstructed Fe3O4(001) surface was studied by scanning tunneling microscopy, x-ray and ultraviolet photoelectron spectroscopy, low-energy electron diffraction (LEED), and density functional theory (DFT). Following deposition at room temperature, metals are either adsorbed as isolated adatoms or fill the subsurface catio

Contrasting Short-Term Antibiotic Effects on Respiration and Bacterial Growth Compromises the Validity of the Selective Respiratory Inhibition Technique to Distinguish Fungi and Bacteria.

The selective inhibition (SI) technique has been widely used to resolve fungal and bacterial biomass. By studying bacterial growth (leucine/thymidine incorporation) and respiration simultaneously, this study demonstrates that the inhibitors the SI technique is based on do not efficiently or specifically resolve fungal and bacterial contributions to respiration. At concentrations that completely in

Simultaneous compression and characterization of ultrashort laser pulses using chirped mirrors and glass wedges

We present a simple and robust technique to retrieve the phase of ultrashort laser pulses, based on a chirped mirror and glass wedges compressor. It uses the compression system itself as a diagnostic tool, thereby making unnecessary the use of complementary diagnostic tools. We used this technique to compress and characterize 7.1 fs laser pulses from an ultrafast laser oscillator. (C)2011 Optical

The Descents of Military Violence against Civilians: a history of the present

Inspired by the works of Michel Foucault and Erling Sandmo, this article explores contemporary discourses of military violence against civilians from a genealogical perspective. The purpose is to shed light on the historicity of certain structures of knowledge, thoughts, politics and ethics that are fundamental for the ways in which military violence against civilians is put into words, interprete

Mean radiant temperature – A predictor of heat related mortality

Abstract Health studies have repeatedly used air temperature (Ta), sometimes adjusted for humidity, when analyzing the impact of weather on mortality. The aim of this study is to highlight the importance of mean radiant temperature (Tmrt) and its impact on heat related mortality. Tmrt is an essential meteorological parameter that influences the thermal comfort (heat load) of humans. It is useful w

An Early Jurassic flora from the Clarence-Moreton Basin, Australia

A low-diversity Early Jurassic flora preserved in floodbasin siltstones of the Marburg Subgroup at Inverleigh Quarry in the Clarence-Moreton Basin, eastern Australia, is dominated by Allocladus helgei Jansson sp. nov., a conifer with denticulate leaves tentatively attributed to Araucariaceae. The assemblage also includes Rintoulia variabilis and Caytoniales, (Caytonia cucullata McLoughlin sp. nov.
