Analysis of prospectively collected data in a national register.

PURPOSE: To evaluate the use of x-ray imaging performed with a high-power laser system in biologic and medical studies. MATERIALS AND METHODS: A compact terawatt laser system based on chirped pulse amplification in titanium-doped sapphire was used. X rays were generated by irradiating a high-atomic-number target (tantalum). RESULTS: When photons with an energy below 10 keV were removed with use of

Background Studies in many countries have reported higher lung cancer incidence and mortality in individuals with lower socioeconomic status. Methods To investigate the role of smoking in these inequalities, we used data from 391 251 participants in the European Prospective Investigation into Cancer and Nutrition study, a cohort of individuals in 10 European countries. We collected information on

This is an exploratory study investigating potential effects of emotional valence in images and their influence on conversation in the presence of the images. We used latent-semantic analysis to generalize valence ratings of Swedish words to a corpus of spoken conversations. Each utterance in the conversation was given a valence rating, which represented how emotionally positive or emotionally neg

The membrane lipid-anchored glypicans (heparan sulfate proteoglycans) are present in both vertebrates and invertebrates and serve as important modulators of growth factors and morphogens during development. Their core proteins are similar and consist of a large N-terminal domain comprising 14 evolutionary conserved cysteines and a C-terminal stalk carrying the heparan sulfate side-chains and the l

Objectives and design. There are conflicting data on gender differences in survival among heart failure (HF) patients. We prospectively assessed gender differences in survival among 930 consecutive patients (464 [49.9%] women, mean age 76.1 +/- 10.1 years), admitted to hospital with suspected or diagnosed HF. Results. Overall, women had lower unadjusted mortality hazard ratio (HR) than men: HR 0.8

BACKGROUND: There is a lack of understanding of the processes that regulate differentiation in the prostate. OBJECTIVE: To determine localisation, activity, and regulation of cytodifferentiation-modulatory proteins in the human adult prostate. DESIGN, SETTINGS, AND PARTICIPANTS: Eighteen volunteering patients with organ-confined prostate cancer were prospectively enrolled at a single university ho

Aim: To study delivery outcome including presence of infant congenital malformations after maternal use of loperamide in early pregnancy. Methods: Using the Swedish Medical Birth Register, women reporting the use of loperamide in early pregnancy were compared with other women for the period July 1, 1995-2004. Odds ratios (OR) or risk ratios (RR) were estimated after adjustment for some variables,

The role of airway clearance in inhaled drug therapy is complex. Disease-induced bronchoconstriction results in a central drug-deposition pattern where mucociliary clearance is most efficient. When drug-induced bronchodilation is achieved, deposition and uptake becomes more peripheral, and because there is less mucociliary clearance in the periphery, this will lead to an unintentional increase in
