Long-term survival of women with basal-like ductal carcinoma in situ of the breast: a population-based cohort study

Background: Microarray gene-profiling of invasive breast cancer has identified different subtypes including luminal A, luminal B, HER2-overexpressing and basal-like groups. Basal-like invasive breast cancer is associated with a worse prognosis. However, the prognosis of basal-like ductal carcinoma in situ (DCIS) is still unknown. Our aim was to study the prognosis of basal-like DCIS in a large pop

Long-term impact of postconditioning on infarct size and left ventricular ejection fraction in patients with ST-elevation myocardial infarction

Background: Ischemic postconditioning (PostC), reperfusion in brief cycles, is known to induce short-term reduction in infarct size in patients with ST elevation myocardial infarction (STEMI), especially among those with large myocardium at risk (MaR). The aim of the present study was to investigate the long-term effect of PostC on infarct size and left ventricular ejection fraction (LVEF). Method

ScFv Anti-Heparan Sulfate Antibodies Unexpectedly Activate Endothelial and Cancer Cells through p38 MAPK: Implications for Antibody-Based Targeting of Heparan Sulfate Proteoglycans in Cancer.

Tumor development requires angiogenesis and anti-angiogenic therapies have been introduced in the treatment of cancer. In this context, heparan sulfate proteoglycans (HSPGs) emerge as interesting targets, owing to their function as co-receptors of major, pro-angiogenic factors. Accordingly, previous studies have suggested anti-tumor effects of heparin, i.e. over-sulfated HS, and various heparin mi

GaMnAs: Layers, Wires and Dots

Thin layers of GaMnAs ferromagnetic semiconductor grown by molecular beam epitaxy on GaAS(001) substrates were studied. To improve their magnetic properties the post-growth annealing procedures were applied, using the surface passivation layers of amorphous arsenic. This post-growth treatment effectively increases the ferromagnetic-to-paramagnetic phase transition temperature in GaMnAs, and provid

Characterization of human papillomavirus subtype 72b.

We report the characterization of human papillomavirus (HPV) subtype 72b of the genus Alphapapillomavirus isolated from an oral rinse sample of a healthy woman. The HPV72b L1 open reading frame (ORF) was 90.2% identical to that of HPV72, indicating a subtype close to the border of a novel HPV type.

Multiple mechanisms of MYCN dysregulation in Wilms tumour.

Genomic gain of the proto-oncogene transcription factor gene MYCN is associated with poor prognosis in several childhood cancers. Here we present a comprehensive copy number analysis of MYCN in Wilms tumour (WT), demonstrating that gain of this gene is associated with anaplasia and with poorer relapse-free and overall survival, independent of histology. Using whole exome and gene-specific sequenci

Plasma phospholipid fatty acid concentrations and risk of gastric adenocarcinomas in the European Prospective Investigation into Cancer and Nutrition (EPIC-EURGAST)

Background: Epidemiologic data suggest that diet is a risk factor in the etiology of gastric cancer. However, the role of dietary fatty acids, a modifiable risk factor, remains relatively unexplored. Objective: The objective of this study was to determine the association of plasma phospholipid fatty acid concentrations, as biomarkers of exogenous and endogenously derived fatty acids, with the risk

Probing the mass-loss history of the unusual Mira variable R Hya through its infrared CO wind

Context. The unusual Mira variable R Hya is well known for its declining period between AD 1770 and 1950, which is possibly attributed to a recent thermal pulse. Aims. The goal of this study is to probe the circumstellar envelope (CSE) around R Hya and to check for a correlation between the derived density structure and the declining period. Methods. We investigate the CSE around R Hya by performi

Mutations and polymorphisms in TP53 gene-an overview on the role in colorectal cancer

A functionally normal TP53 is essential to protect organisms from developing cancer. Somatic mutations in the gene represent one of the highest recurring perturbations in human tumours, including colorectal cancer (CRC). However, the variegated phenotype of wide spectrum of somatic mutations in TP53 and the complexity of the disease prevent a straight interpretation of the mutational analysis in t

Mapping of quantitative trait loci for floral scent compounds in cowpea (Vigna unguiculata L.)

Floral scent is a very important trait in plant evolution. Currently, little is known about the inheritance of floral scent in cowpea (Vigna unguiculata L.) or changes that might have occurred during its domestication. Therefore, we analysed scent volatiles and molecular markers in a population of 159 F7 recombinant inbred lines derived from a cross of a domesticated blackeye cowpea cultivar, ‘524

MicroRNA-124 Is a Subventricular Zone Neuronal Fate Determinant.

New neurons are continuously generated from neural stem cells with astrocyte properties, which reside in close proximity to the ventricle in the postnatal and adult brain. In this study we found that microRNA-124 (miR-124) dictates postnatal neurogenesis in the mouse subventricular zone. Using a transgenic reporter mouse we show that miR-124 expression is initiated in the rapid amplifying progenit

Crosstalk between Inflammation and Coagulation in Acute Pancreatitis - Experimental and Clinical Studies.

Popular Abstract in Swedish Akut pankreatit (AP) är en inflammation i bukspottskörteln, som oftast utlöses av gallstenssjukdom eller alkoholintag. Varför man får akut pankreatit vet man inte och inte heller varför de flesta patienter återhämtar sig på ett par dagar, medan ca 20 procent drabbas av en betydligt svårare form av sjukdomen. Vid svår AP ses en kraftig inflammatorisk reaktion i hela kropIn various inflammatory conditions a close interplay between inflammation and coagulation is known to exist, where coagulation factor VII (FVII) and tissue factor (TF) are considered to be pivotal players. In this thesis the crosstalk between inflammation and coagulation in acute pancreatitis (AP) has been investigated. The results from the first paper, where active site inactivated FVII (FVIIai)

Porren inför lagen. Två fallstudier angående den officiella attityden till offentligt visad pornografisk film 1921 och 1971

In this article, two case studies from 1921–22 and 1971 respectively, are juxtaposed in order to determine change in official attitudes and screening contexts for pornographic films. Focusing in the first case on an exhibitor who in 1922 was convicted of screening an obscene film on three occasions the year before, and in the other case on the range of venues for pornographic films in Malmö the mo

Evaluation of Cold Workplaces: An Overview of Standards for Assessment of Cold Stress

Many persons world wide are exposed to cold environments, either indoors for example in cold stores, or outdoors. Cold is a hazard to health and may affect safety and performance of work. Basis for the creation of safe and optimal working conditions may be obtained by the application of relevant international standards. ISO 11079(1)) presents a method for evaluation of whole body heat balance. On

Accurate free atom-solid binding energy shifts for Au and Ag

Binding energy shifts between atomic and solid states have been observed with improved accuracy for All 4f and Ag 3d core levels applying a simultaneous measurement method. Also the 3d photoelectron spectrum and binding energies of free Ag atoms have been observed for the first time. New values determined as free atom to bulk solid shifts deviate considerably from previous estimate for Au but agre

Investigating spatial differentiation of model parameters in a carbon cycle data assimilation system

Better estimates of the net exchange of CO(2) between the atmosphere and the terrestrial biosphere are urgently needed to improve predictions of future CO(2) levels in the atmosphere. The carbon cycle data assimilation system (CCDAS) offers the capability of inversion, while it is at the same time based on a process model that can be used independent of observational data. CCDAS allows the assimil
