Early changes in bone mineral density measured by digital X-ray radiogrammetry predict up to 20 years radiological outcome in rheumatoid arthritis.

ABSTRACT: INTRODUCTION: Change in bone mineral density (BMD) in the hand, as evaluated by digital X-ray radiogrammetry (DXR) of the II-IV metacarpal bones, has been suggested to predict future joint damage in rheumatoid arthritis (RA). This study's objective was to investigate if DXR-BMD loss early in the disease predicts development of joint damage in RA patients followed for up to 20 years. METH

Covarying Hydroclimate Patterns between Monsoonal Asia and North America over the Past 600 Years

Proxy data with large spatial coverage spanning to the preindustrial era not only provide invaluable material to investigate hydroclimate changes in different regions but also enable studies on temporal changes in the teleconnections between these regions. Applying the singular value decomposition (SVD) method to tree-ring-based field reconstructions of the Palmer drought severity index (PDSI) ove

Predicting C aromaticity of biochars based on their elemental composition

Three models were examined to predict C aromaticity (f(a)) of biochars based on either their elemental composition (C, H, N and O) or fixed C (FC) content. Values of f(a) from solid state C-13 nuclear magnetic resonance (NMR) analysis with Bloch-decay (BD) or direct polarisation (DP) techniques, concentrations of total C, H, N, and organic O, and contents of FC of 60 biochars were either compiled

Label-free somatic cell cytometry in raw milk using acoustophoresis.

A microfluidic system for cell enumeration in raw milk was developed. The new method, preconditions the milk sample using acoustophoresis that removes lipid particles which are larger than a few micrometers. The acoustophoretic preprocessing eliminates the need for conventional sample preparation techniques, which include chemical solvents, cell labeling and centrifugation, and facilitates rapid c

Contact allergy from disperse dyes in textiles-a review.

Several disperse dyes (DDs) are still considered to be the most important allergens in textile dermatitis, but there are sparse data about their current use in textiles. The aim of this review was to evaluate published studies and reports on contact allergy to DDs published in PubMed during the last 22 years (1990-2012). Prevalence data are provided by study and by dye, as well as by the described

Epidermal growth factor receptor status and persistent activation of Akt and p44/42 MAPK pathways correlate with the effect of cetuximab in head and neck and colon cancer cell lines.

OBJECTIVE: The aim of this study was to investigate the effect of epidermal growth factor receptor (EGFR) blockade on cell survival and on downstream signalling pathways using the monoclonal antibody cetuximab. METHODS: We used three colon cancer cell lines, of which one was EGFR-negative, and two head and neck squamous cell carcinoma (HNSCC) lines. EGFR expression and gene copy number were measur

Skin care products containing low concentrations of formaldehyde detected by the chromotropic acid method can not be safely used in formaldehyde-allergic patients.

Preservatives are widely used to prevent microbial growth both for skin care products and in the industry. Many of them have allergic potential. Allergic contact dermatitis caused by preservatives can often be chronic, probably because it is difficult to suspect contact allergy to these chemicals based on the patient's history only. Formaldehyde is a common cause of contact allergy and has been in

Exposure to persistent organic pollutants and sperm DNA methylation changes in Arctic and European populations.

Persistent organic pollutants (POPs), such as PCBs (polychlorinated biphenyls) and DDT [1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane], are environmental contaminants with potential endocrine disrupting activity. DNA methylation levels in peripheral blood lymphocytes have been associated with serum concentrations of POPs in Greenland Inuit and Korean populations. Greenland Inuits are characterized

Stimulation of blood mononuclear cells with bacterial virulence factors leads to the release of pro-coagulant and pro-inflammatory microparticles.

Severe infectious diseases remain a major and life-threatening health problem. In serious cases a systemic activation of the coagulation cascade and hypovolemic shock are critical complications that are associated with high mortality rates. Here we report that blood mononuclear cells, stimulated with M1 protein of Streptococcus pyogenes or other bacterial virulence factors, produce not only pro-co

Clinical Fluorescence Diagnosis of Human Bladder-carcinoma Following Low-dose Photofrin Injection

A point-monitoring fluorescence diagnostic system based on a low-energy pulsed laser, fiber transmission optics, and an optical multichannel analyzer was used for diagnosis of patients with bladder malignancies. Twenty-four patients with bladder carcinoma, carcinoma in situ, and/or dysplasia were injected with hematoporphyrin derivative, Photofrin, 0.35 or 0.5 mg/kg body weight, forty-eight hours

fMRI memory assessment in healthy subjects: a new approach to view lateralization data at an individual level.

We present a comprehensive and clinically applicable fMRI test-including both a verbal and a visuospatial task-for assessment of hemispheric specific memory in the medial temporal lobe (MTL). fMRI data was collected from 15 healthy right-handed volunteers. Whole-brain activation was analyzed as well as activation in two regions of interest: the MTL and the anterior speech area. Laterality indices

Adhesive Mechanisms of Histone-Induced Neutrophil-Endothelium Interactions in the Muscle Microcirculation.

Extracellular histones released during cell damage have the capacity to cause tissue injury associated with increased leukocyte accumulation. However, the molecular mechanisms regulating histone-induced leukocyte recruitment remain elusive. The objective of this study was to examine the role of adhesion molecules in histone-dependent leukocyte accumulation by use of intravital microscopy of the mo

Occupational allergic contact dermatitis caused by sterile non-latex protective gloves: clinical investigation and chemical analyses.

Background An increased frequency of occupational contact hand dermatitis among surgical operating theatre personnel has been noticed. Objectives To evaluate patients with occupational contact dermatitis caused by their rubber gloves, and to describe a method for analysing the content of the allergens in the gloves. Materials and methods Patch tests were performed with the baseline series, a rubbe

Collected World and Single Center Experience With Endovascular Treatment of Ruptured Abdominal Aortic Aneurysms.

BACKGROUND:: Case and single center reports have documented the feasibility and suggested the effectiveness of endovascular aneurysm repair (EVAR) of ruptured abdominal aortic aneurysms (RAAAs), but the role and value of such treatment remain controversial. OBJECTIVE:: To clarify these we examined a collected experience with use of EVAR for RAAA treatment from 49 centers. METHODS:: Data were obtai
