EPO-independent functional EPO receptor in breast cancer enhances estrogen receptor activity and promotes cell proliferation.

The main function of Erythropoietin (EPO) and its receptor (EPOR) is the stimulation of erythropoiesis. Recombinant human EPO (rhEPO) is therefore used to treat anemia in cancer patients. However, clinical trials have indicated that rhEPO treatment might promote tumor progression and has a negative effect on patient survival. In addition, EPOR expression has been detected in several cancer forms.

Impacts of an aggressive riparian invader on community structure and ecosystem functioning in stream food webs

P>1. Bioassessment in running waters has focused primarily on the impacts of organic pollution on community structure. Other stressors (e.g. invasive species) and impacts on ecosystem processes have been largely ignored in many riverine biomonitoring schemes, despite being required increasingly by environmental legislation. 2. Exotic riparian plants can exert potentially powerful stresses by alter

Second primary cancers after cancer of unknown primary in Sweden and Germany: efficacy of the modern work-up.

In unsparing efforts to find the hidden primaries, second primary cancers (SPCs) unrelated to cancer of unknown primary (CUP) are found. The detection rates of SPCs after CUP can be considered as measures for the effectiveness of modern diagnostic techniques in finding tumors. We aimed to compare the rates of specific SPCs found after the work-up of CUP and the more sign/symptom-directed diagnosti

Inner-shell photoionization of atomic chlorine

Relative partial cross sections have been measured following photoexcitation of atomic chlorine near the Cl 2p and Cl 1s ionization thresholds. In addition, Breit-Pauli R-matrix calculations have been carried out in the region of the 2p thresholds, and the results are compared with experiment. Owing to angular-momentum considerations, it was found that the resonances associated with the higher 2p(

Classic Bladder Exstrophy: Frequent 22q11.21 Duplications and Definition of a 414 kb Phenocritical Region

Background: Classic bladder exstrophy (CBE) is the most common form of the bladder exstrophy and epispadias complex. Previously, we and others have identified four patients with a duplication of 22q11.21 among a total of 96 unrelated CBE patients. Methods: Here, we investigated whether this chromosomal aberration was commonly associated with CBE/bladder exstrophy and epispadias complex in an exten

Novel Assay of Metformin Levels in Patients With Type 2 Diabetes and Varying Levels of Renal Function Clinical recommendations

AbstractObjective: To study trough levels of metformin in serum and its intra individual variation in patients using a newly developed assay. Research Design and Methods: Trough serum levels of metformin was measured once using Liquid Chromatography Tandem Mass Spectrometry (LcMSMS) in 137 type 2 diabetes patients with varying renal function (99 men) and followed repeatedly during two months in 20

Development and validation of the Fast Assessment in Acute Treatment of Psychosis-Observation Rating Scale (FAST-O)

Objectives. There is a need for an observation scale for assessment and monitoring of acutely psychotic patients. Milestones based on such ratings should be defined, similar to the PANSS-based Remission criteria. FAST-O is such an instrument (11 items and a CGI rating). Methods. Reliability, validity and factor structure were analyzed in four separate studies-most importantly in one study of 33 ch

Gene-centric meta-analyses for central adiposity traits in up to 57 412 individuals of European descent confirm known loci and reveal several novel associations

Waist circumference (WC) and waist-to-hip ratio (WHR) are surrogate measures of central adiposity that are associated with adverse cardiovascular events, type 2 diabetes and cancer independent of body mass index (BMI). WC and WHR are highly heritable with multiple susceptibility loci identified to date. We assessed the association between SNPs and BMI-adjusted WC and WHR and unadjusted WC in up to

The prevalence of clinically diagnosed ankylosing spondylitis and its clinical manifestations: a nationwide register study.

Prevalence estimates of ankylosing spondylitis vary considerably, and there are few nationwide estimates. The present study aimed to describe the national prevalence of clinically diagnosed ankylosing spondylitis in Sweden, stratified according to age, sex, geographical, and socio-economic factors, and according to subgroups with ankylosing spondylitis-related clinical manifestations and pharmacol

Enabler for safety improvements in air traffic control – Development of a tool to identify and monitor work and situational factors

Air traffic control activities demand a high level of safety performance. Methods for identifying and monitoring work and situational factors to enable safety performance improvements are rare. This paper reports on the development of such a questionnaire-based tool for the Swedish air navigation services provider. Results from interviews specified eight aspects to be assessed by the questionnaire

Downregulation of Angiogenesis Factors, VEGF and PDGF, after Rapid IgE Desensitization and Oral Immunotherapy in Children with Food Allergy

Background. Angiogenesis has a key role in several conditions and is regulated by several factors such as the platelet-derived growth factor (PDGF) or the vascular endothelial growth factor (VEGF). The goal of this study was to investigate the possible role of PDGF and VEGF in a group of patients with severe food allergy. Methods. We design a prospective longitudinal study (n = 30) with patients w

Development of new criteria for cortical bone histomorphometry in femoral neck: intra- and inter-observer reproducibility

Histomorphometry is commonly applied to study bone remodeling. Histological definitions of cortical bone boundaries have not been consistent. In this study, new criteria for specific definition of the transitional zone between the cortical and cancellous bone in the femoral neck were developed. The intra- and inter-observer reproducibility of this method was determined by quantitative histomorphom

TERT promoter mutations in melanoma survival.

Despite advances in targeted therapies, the treatment of advanced melanoma remains an exercise in disease management, hence a need for biomarkers for identification of at risk primary melanoma patients. In this study we aimed to assess the prognostic value of TERT promoter mutations in primary melanomas. DNA from 300 patients with stage I/II melanoma was sequenced for TERT promoter and BRAF/NRAS m

Porous silicon antibody microarrays for quantitative analysis: Measurement of free and total PSA in clinical plasma samples.

The antibody microarrays have become widespread, but their use for quantitative analyses in clinical samples has not yet been established. We investigated an immunoassay based on nanoporous silicon antibody microarrays for quantification of total prostate-specific-antigen (PSA) in 80 clinical plasma samples, and provide quantitative data from a duplex microarray assay that simultaneously quantifie
