Exposure to cadmium and persistent organochlorine pollutants and its association with bone mineral density and markers of bone metabolism on postmenopausal women.

Environmental contaminants such as cadmium and persistent organochlorine pollutants have been proposed as risk factors of osteoporosis, and women may be at an increased risk. To assess associations between exposure to cadmium and two different POPs (2,2',4,4',5,5'-hexachlorobiphenyl CB-153, 1,1-dichloro-2,2-bis(p-chlorophenyl)-ethylene p,p'-DDE), on one hand, and bone effects, on the other, in a p

Isolation and killing of candidate chronic myeloid leukemia stem cells by antibody targeting of IL-1 receptor accessory protein.

Chronic myeloid leukemia (CML) is genetically characterized by the Philadelphia (Ph) chromosome, formed through a reciprocal translocation between chromosomes 9 and 22 and giving rise to the constitutively active tyrosine kinase P210 BCR/ABL1. Therapeutic strategies aiming for a cure of CML will require full eradication of Ph chromosome-positive (Ph(+)) CML stem cells. Here we used gene-expression

Impaired nerve regeneration and Schwann cell activation after repair with tension.

The aim was to investigate the relation between axonal outgrowth (neurofilaments) and Schwann cell activation (activating transcription factor 3) and apoptosis (caspase 3) 10 days after nerve repair with no, minor (3 mm defect) and moderate (6 mm defect) tension in rat sciatic nerve using immunohistochemistry. After repair with no tension, axons grew 11.75 mm, but repair with minor and moderate te

The burden of ankylosing spondylitis in Spain.

OBJECTIVE: To investigate the burden of ankylosing spondylitis (AS) in Spain, as baseline for economic evaluation of the use of biological agents. METHODS: A cross-sectional retrospective observational study was performed in 601 patients with AS in Spain, using a methodology developed in studies in the United Kingdom and Canada. Patients were mailed a questionnaire asking about their health-care c

Mild hypothermia reduces acute mortality and improves hemodynamic outcome in a cardiogenic shock pig model.

INTRODUCTION: Cardiogenic shock is the main cause of death in patients hospitalized due to an acute myocardial infarction. Mild hypothermia reduces metabolism and could offer protective effects for this condition. The aim of our study was to investigate if mild therapeutic hypothermia would improve outcome and hemodynamic parameters in an ischemic cardiogenic shock pig model. METHODS: Twenty-five

Metabolic activation of 2-amino-1-methyl-6-phenylimidazo [4,5-b]pyridine and DNA adduct formation depends on p53: Studies in Trp53(+/+),Trp53(+/-) and Trp53(-/-) mice.

The expression of the tumor suppressor p53 can influence the bioactivation of, and DNA damage induced by, the environmental carcinogen benzo[a]pyrene, indicating a role for p53 in its cytochrome P450 (CYP)-mediated biotransformation. The carcinogen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), which is formed during the cooking of food, is also metabolically activated by CYP enzymes, par

Life satisfaction and self-reported impairments in persons with late effects of polio.

OBJECTIVE: Decades after an acute poliomyelitis infection many persons experience new symptoms or impairments which may affect their life satisfaction. The objective of this study was to investigate the association between life satisfaction and self-reported impairments in persons with late effects of polio. MATERIAL AND METHODS: One hundred and sixty-nine persons (104women and 65men) with prior p

N-cadherin is dispensable for pancreas development but required for beta-cell granule turnover.

The cadherin family of cell adhesion molecules mediates adhesive interactions that are required for the formation and maintenance of tissues. Previously, we demonstrated that N-cadherin, which is required for numerous morphogenetic processes, is expressed in the pancreatic epithelium at E9.5, but later becomes restricted to endocrine aggregates in mice. To study the role of N-cadherin during pancr

ENSAM: Europium Nanoparticles for Signal Enhancement of Antibody Microarrays on Nanoporous Silicon.

To improve the sensitivity of antibody microarray assays, we developed ENSAM ( Europium Nanoparticles for Signal enhancement of Antibody Microarrays). ENSAM is based on two nanomaterials. The first is polystyrene nanoparticles incorporated with europium chelate (beta-diketone) and coated with streptavidin. The multiple fluorophores incorporated into each nanoparticle should increase signal obtaine

Bell's palsy - the effect of prednisolone and/or valaciclovir versus placebo in relation to baseline severity in a randomised controlled trial.

Objectives: To evaluate the treatment effect of prednisolone and/or valaciclovir in Bell's palsy patients with different baseline severity of palsy. Design: Patient data were collected from the Scandinavian Bell's Palsy Study, a prospective, randomized, double-blind, placebo-controlled, multi-centre trial. Setting: Sixteen otorhinolaryngological centres in Sweden and one in Finland. Particip
