The 17 beta-hydroxysteroid dehydrogenase 1 gene (HSD17B1) encodes 17HSD1, which catalyzes the final step of estradiol biosynthesis. Despite the important role of HSD17B1 in hormone metabolism, few epidemiologic studies of HSD17B1 and breast cancer have been conducted. This study includes 5,370 breast cancer cases and 7,480 matched controls from five large cohorts in the Breast and Prostate Cancer

The aim of the paper is to critically review the notion of social capital and review empirical literature on the association between social capital and health across countries. The methodology used for the review includes a systematic search on electronic databases for peer-reviewed published literature. We categorize studies according to level of analysis (single and multilevel) and examine wheth

Self-desiccation occurs in all types of concrete due to the chemical shrinkage that takes place when water is attached to the cement. In High Performance Concrete the low porosity makes the effect of self-desiccation much more pronounced. This paper presents a summary of a Nordic Seminar on Self-Desiccation in Concrete held in Lund. For this purpose aspects of mix design, curing conditions, desicc

Articles about the value of literature, based on lectures given at the conference "The Value of Literature. The contribution of literature, literary history and theory to cultural, ethical and social development", held at Vitterhetsakademien, Stockholm Nov 2004.

Double-tagged interactions of photons with virtualities Q(2) between 10 GeV2 and 200 GeV2 are studied with the data collected by DELPHI at LEPII from 1998 to 2000, corresponding to an integrated luminosity of 550 pb(-1). The gamma*gamma* -> mu(+)mu(-) data agree with QED predictions. The cross-section of the reaction gamma*gamma* -> hadrons is measured and compared to the LO and NLO BFKL calculati

Background: Pancreatic cancer is generally associated with a poor prognosis and often diagnosed in an advanced stage. The aim of the present study was to evaluate gemcitabine treatment concerning prognostic factors, clinical benefit, tolerance/ toxicity and survival. Methods: Patients with surgically nonresectable, locally advanced or metastatic pancreatic cancer treated with gemcitabine were incl

Resonant Auger spectra of O-2 clusters excited at the O1s edge are reported. After excitation to the repulsive 1s(-1)3 sigma* state, the resulting resonant Auger spectrum displays features that remain constant in kinetic energy as the photon energy is detuned. The shift between known atomic fragment features and these features is consistent with that observed for atoms and clusters in singly charg

Abstract in French Cet article pose la question de savoir s’il existe une corrélation entre le niveau grammatical et le niveau lexical dans la production écrite d’apprenants de français langue étrangère. Nous avons appliqué un certain nombre d’indices quantitatifs et lexicaux et un indice grammatical à 40 textes en français, écrits par deux groupes d’apprenants adultes suédophones se situant à desThe paper addresses the question of whether there is a correlation between the grammatical developmental level and the lexical developmental level in the written production of learners of French as a foreign language. We have applied a number of quantitative and lexical measures and one grammatical measure to 40 texts in French written by two groups Swedish adults with different proficiency levels

The phase behavior over the entire concentration range for the system didodecyldimethylammonium bromide (DDAB)-sodium taurodeoxycholate (STDC)-water, at 25 degrees C, has been investigated, with emphasis on the DDAB-rich part. Polarizing microscopy, SAXS, H-2 NMR and H-1 self-diffusion NMR have been used in combination as probing techniques for phase behavior and microstructure. The system forms f

Post-shift and next-morning urine was sampled from workers exposed to hexahydrophtalic anhydride (HHPA), an epoxy hardener, sensitising at low exposure levels. Exposure levels of HHPA in air (gas chromatography, GC) in the range of 30-270 micrograms/m3 corresponded to urinary concentrations of 0.9-2.8 mumol hexahydrophthalic acid (HHP acid; GC-mass spectrometry)/mmol creatinine. In the morning sam

Objective. Selective leukocyte apheresis is a new type of non-pharmacological treatment for patients with active ulcerative colitis and Crohn's disease. Preliminary data have indicated that this type of therapy is safe and efficacious, and large sham-controlled studies are currently in progress. In Scandinavia, a substantial number of patients with chronic inflammatory bowel disease have already r

Objective: To compare 5% albumin, 6% dextran 70, 3.5% gelatin, 6% hydroxyethyl starch 130/0.4, and saline regarding their plasma volume expanding effect after a surgical skeletal muscle trauma and their simultaneous effects on transvascular fluid exchange in skeletal muscle. Design: Controlled, prospective, randomized laboratory study. Setting: University research laboratory. Subjects: Thirty-six

A novel prenylated isoflavanone, sigmoidin I, has been isolated from the roots of Erythrina sigmoidea, in addition to the known isoflavones, corylin and neobavaisoflavone and the known pterocarpan, phaseollidin. Its structure was established as 7,4'-dihydroxy-3'-methoxy-5'-(3-methylbut-2-enyl) isoflavanone by means of spectroscopic analyses and chemical transformations. Neobavaisoflavone displayed

I uppsatsen jämförs Rydbergs artiklar med hans roman Fribytaren på Östersjön. Kyrkokritiken är allvarligare, djupare och bredare i romanen trots att artiklarna är mer "rakt på sak".
