[The effect of multimorbidity on functional and quality of life outcomes in women with generalized osteoarthritis].

Introduction: Osteoarthritis (OA) as the most common joint disease is a major public health concern.

Aim: To investigate the effect of multimorbidity on functional and quality of life outcomes in women with generalized osteoathritis (hand and knee arthritis, GOA).

Method: In this cross-sectional study, patients according to the American College of Rheumatology (ACR) criteria for OA were invited.

Musculoskeletal ultrasonography in routine rheumatology practice: data from Central and Eastern European countries.

The main aim was to gain structured insight into the use of musculoskeletal ultrasonography (MSUS) in routine rheumatology practices in Central and Eastern European (CEE) countries. In a cross-sectional, observational, international, multicenter survey, a questionnaire was sent to investigational sites in CEE countries. Data on all subsequent routine MSUS examinations, site characteristics, MSUS equipment, and investigators were collected over 6 months or up to 100 examinations per center.

Investigation of the protective properties of glycosylphosphatidylinositol-based vaccine candidates in a Toxoplasma gondii mouse challenge model.

Vaccination against the ubiquitous parasite Toxoplasma gondii would provide the most efficient prevention against toxoplasmosis-related congenital, brain and eye diseases in humans. We investigated the immune response elicited by pathogen-specific glycosylphosphatidylinositol (GPI) glycoconjugates using carbohydrate microarrays in a BALB/c mouse model. We further examined the protective properties of the glycoconjugates in a lethal challenge model using the virulent T.

Contributions of ultrasound beyond clinical data in assessing inflammatory disease activity in rheumatoid arthritis: current insights and future prospects.

Appropriate measures of disease activity need to be valid, reliable and sensitive to change for use in clinical studies while remaining at the same time feasible and practicable for utilization in daily clinical practice. Ultrasonography was shown to be a valid, sensitive and reliable imaging modality for the detection of synovitis in RA, however, it has so far failed to demonstrate superior sensitivity to change as compared with clinical examination. This review examines the current evidence for the use of established measures and/or US, either as an alternative or as a supplementary measure to clinical examination, as tools for monitoring synovitis in RA.

Prevalence of comorbidities in rheumatoid arthritis and evaluation of their monitoring: results of an international, cross-sectional study (COMORA).

Background: PATIENTS with rheumatoid arthritis (RA) are at increased risk of developing comorbid conditions.

Objectives: To evaluate the prevalence of comorbidities and compare their management in RA patients from different countries worldwide.

Study Design: international, cross-sectional.

Regulation of mRNA expression in drug-sensitive and drug-resistant gastric carcinoma cells is independent of YB-1 expression.

Y-Box protein 1 (YB-1) is a multifunctional cellular protein expressed in a range of mammalian cells, including human cancer cells. It is involved in the regulation of various genes including cancer-associated genes, but the full range of target genes and regulatory mechanisms have not been fully elucidated. To identify global mRNA expression patterns that are potentially regulated by YB-1, a previously established and well-characterized cell model derived from drug-sensitive (EPG85-257P/tetR/YB-1) and multidrug-resistant (EPG85-257RDB/tetR/YB-1) gastric carcinoma cells in which the expression of YB-1 can be inhibited by tetracycline-dependent activation of the RNA interference (RNAi) pathway, was analyzed by microarray technology.

Effect of YB-1 on the regulation of micro RNA expression in drug-sensitive and drug-resistant gastric carcinoma cells.

The multifunctional Y-Box protein 1 (YB-1) exerts positive and negative regulatory effects on gene expression by different mechanisms. Since transcription can be controlled by micro RNAs (miRNAs), YB-1 could also cause effects on gene expression by regulation of cellular miRNAs. To test this hypothesis, a previously established and well-characterized cell model derived from drug-sensitive (EPG85-257P/tetR/YB-1) and multidrug-resistant (EPG85-257RDB/tetR/YB-1) gastric carcinoma cells, in which the expression of YB-1 can be inhibited by tetracycline-dependent triggering of the RNA interference (RNAi) pathway, was investigated concerning their miRNA expression profiles in the presence and absence of YB-1.
