Modelling the benefits of early diagnosis of pancreatic cancer using a biomarker signature.

Pancreatic cancer (PC) has a poor prognosis, with a 5-year survival of 3-4%. This is mainly due to late diagnosis because of diffuse symptoms, where 80-85% of the patients are inoperable. Consequently, early diagnosis would be of significant benefit, resulting in a potential 5-year survival of 30-40%. However, new technologies must be carefully evaluated concerning effectiveness and healthcare cos

Identification of B-cell lymphoma subsets by plasma protein profiling using recombinant antibody microarrays.

B-cell lymphoma (BCL) heterogeneity represents a key issue, often making the classification and clinical management of these patients challenging. In this pilot study, we outlined the first resolved view of BCL disease heterogeneity on the protein level by deciphering disease-associated plasma biomarkers, specific for chronic lymphocytic leukemia, diffuse large B-cell lymphoma, follicular lymphoma

Genome-Wide Association Study of Blood Pressure Extremes Identifies Variant near UMOD Associated with Hypertension

Hypertension is a heritable and major contributor to the global burden of disease. The sum of rare and common genetic variants robustly identified so far explain only 1%-2% of the population variation in BP and hypertension. This suggests the existence of more undiscovered common variants. We conducted a genome-wide association study in 1,621 hypertensive cases and 1,699 controls and follow-up val

Habitat and Habitus: Boxed-in versus Box-Breaking Research

This paper argues that scholarly work is increasingly situated in narrowly circumscribed areas of study, which are encouraging specialization, incremental adding-to-the-literature contributions and a blinkered mindset. Researchers invest considerable time and energy in these specialized areas in order to maximize their productivity and career prospects. We refer to this way of doing research and s

Global Upper Ordovician correlation by means of delta C-13 chemostratigraphy: implications of the discovery of the Guttenberg delta C-13 excursion (GICE) in Malaysia

Apart from a single study of the early Katian delta C-13 chemostratigraphy in two regions in China, no investigations of the Sandbian and Katian chemostratigraphy have been published from anywhere in Asia. A recent study of the conodont biostratigraphy of the classical Ordovician succession on Langkawi Islands, peninsular Malaysia, showed the presence there of strata coeval with those having the G

Trends in the first decade of 21st century healthcare utilisation in a rheumatoid arthritis cohort compared with the general population.

PURPOSE: To study 21st century trends in healthcare utilisation by patients with rheumatoid arthritis (RA) compared with the general population. METHODS: Observational cohort study. Using Swedish healthcare register data, we identified 3977 Region Skåne residents (mean age in 2001, 62.7 years; 73% women) presenting with RA (International Classification of Diseases-10 codes M05 or M06) in 1998-2001

Suberythemal Sun Exposures at Swedish Schools Depend on Sky Views of the Outdoor Environments - Possible Implications for Pupils' Health.

More scheduled outdoor stay is increasingly advocated for school children. This study measured 2(nd) , 5(th) and 8(th) graders' erythemal UV-exposure in September, March and May at four Swedish schools. We related those exposures, as fractions of total available ambient radiation, to the schools outdoor environments differing in amount of shade, vegetation, and peripheral city-scape quantified as

Prymnesium parvum invasion success into coastal bays of the Gulf of Mexico: Galveston Bay case study

The toxic haptophyte Prymnesium parvum regularly forms fish-killing blooms in inland brackish water bodies in the south-central USA. Along the Texas coast smaller blooms have occurred in isolated areas. There appears to be an increasing risk that harmful P. parvum blooms will propagate into open coastal waters with implementation of future water plans. These plans will include increased interbasin

Nonlinear compartmental model of F-18-choline

Introduction: This work develops a compartmental model of F-18-choline in order to evaluate its biokinetics and so to describe the temporal variation of the radiopharmaceuticals' uptake in and clearance from organs and tissues. Methods: Ten patients were considered in this study. A commercially available tool for compartmental analysis (SAAM II) was used to model the values of activity concentrati

Molecular Rift: Virtual Reality for Drug Designers

Recent advances in interaction design have created new ways to use computers. One example is the ability to create enhanced 3D environments that simulate physical presence in the real world a virtual reality. This is relevant to drug discovery since molecular models are frequently used to obtain deeper understandings of, say, ligand protein complexes. We have developed a tool (Molecular Rift), whi

Regional differences in birth size: a comparison between the Helsinki Birth Cohort Study and contemporaneous births on the Åland Islands.

The Åland Islands were recently ranked as Finland's healthiest region with lower prevalence of several non-communicable diseases compared with the national mean. We have compared birth characteristics of 1697 individuals born on the Åland Islands between 1937 and 1944 with contemporaneous data from the Helsinki Birth Cohort Study (HBCS; n=11,808). This is a first step towards a potential future an

Parental Education and Offspring Outcomes: Evidence from the Swedish Compulsory School Reform

We use the Swedish compulsory school reform to estimate the causal effect of parental education on sons’ outcomes. To this end, we use data from the Swedish military enlistment register on the entire population of males and consider outcomes such as cognitive skills, non-cognitive skills, and various dimensions of health at the age of 18. We find positive effects of maternal education on sons' ski

Discovery-based Protein Expression Profiling Identifies Distinct Subgroups and Pathways in Leiomyosarcomas.

Soft tissue sarcomas (STS) are malignant tumors of mesenchymal origin. A substantial portion of these tumors exhibits complex karyotypes and lack characterized chromosomal aberrations. Owing to such properties, both histopathological and molecular classification of these tumors has been a significant challenge. This study examines the protein expression of a large number of human softtissue sarcom

The analgesic effect of oxygen during percutaneous coronary intervention (the OXYPAIN Trial).

Abstract Introduction: Oxygen is considered to have analgesic effects, but the evidence is weak. Oxygen may be harmful to the ischemic myocardium. The aim was to investigate the analgesic effect of oxygen during percutaneous coronary intervention (PCI) and to evaluate cardiac injury. Material and methods: The OXYPAIN was a phase II randomized trial with a double blind design. 305 patients were ran

Preparation of hydrophilic poly(3-hydroxybutyrate) macroporous scaffolds through enzyme-mediated modifications

Scaffolds made from poly(3-hydroxybutyrate) were prepared by thermally induced phase separation from solutions in dioxane at temperatures above (23 degrees C) or below the freezing point of the solvent. At 23 degrees C, gelation occured with nano-fibrous network formation. The scaffolds prepared at -12 degrees C and -25 degrees C exhibited a highly porous morphology, with pores in the range of 3-2

Status of the ESS Cryogenic System

The European Spallation Source (ESS) is a neutron science facility funded by a collaboration of 17 European countries currently under design and construction in Lund, Sweden. The centerpiece of ESS is a 2.5 GeV proton linac utilizing superconducting RF cavities operating at 2 K. In addition to cooling the SRF cavities, cryogenics is also used at ESS in the liquid hydrogen moderators surrounding th
