Airway inflammation evaluated in a human nasal lipopolysaccharide challenge model by investigating the effect of a CXCR2 inhibitor.

BACKGROUND: The existence of a link between inflammation in upper and lower airways is well established. It may therefore be assumed that the nose could be used to study inflammatory events in the lower airways. OBJECTIVE: This study aimed to evaluate a lipopolysaccharide (LPS) nasal challenge model by investigating the effect of the CXCR2 inhibitor AZD8309 on neutrophilic inflammation. METHODS: A

Patch testing with the textile dyes Disperse Orange 1 and Disperse Yellow 3 and some of their potential metabolites, and simultaneous reactions to para-amino compounds.

Background: It is known that, in vitro, human skin bacteria are able to split disperse azo dyes into the corresponding aromatic amines, some of which are sensitizers in the local lymph node assay. We hypothesize that the molecules of disperse dyes migrate onto the skin while garments are worn, and are metabolized and degraded by commensal skin bacteria. These molecules penetrate the skin and induc

Looking back at the start of the bone and joint decade what have we learnt?

The Bone and Joint Decade 2000-2010 started as a Swedish initiative in 1996 leading to the UN declaration 1999 followed by the WHO launch 2000. A ten year multidisciplinary and global endeavor moving musculoskeletal conditions onto the research and health agenda is now recognized. Some lessons learned during the journey are presented.

Laser-induced Fluorescence Studies of Meso-tetra(hydroxyphenyl)chlorin In Malignant and Normal-tissues In Rats

meso-Tetra(hydroxyphenyl)chlorin (mTHPC) is an attractive second-generation dihydroporphyrin photosensitiser for use in photodynamic therapy. In this study, 1.3mgkg(-1) body weight mTHPC was administered intravenously, and laser-induced fluorescence was used to characterise and compare its localisation and retention in different rat tissues, including an induced experimental adenocarcinoma, 24 h a

Structural determinants in the platelet-derived growth factor alpha-receptor implicated in modulation of chemotaxis

Activation of the platelet-derived growth factor (PDGF) beta-receptor leads to cell growth and chemotaxis. The PDGF alpha-receptor also mediates a mitogenic signal, but fails to induce cell migration in certain cell types. To examine this difference in signal transduction, a series of point-mutated PDGF alpha-receptors were analyzed. Porcine aortic endothelial cells expressing mutant PDGF alpha-re

Governing the transition to low-carbon energy and transport systems

For reprint orders, please contact reprints@ future-science. com stakeholders, markets and institutions. Experience shows that straightforward regulation can be justifiable and effective in some areas (eg, building codes and appliance standards), benefit sharing schemes are often important to ensure stakeholder buy-in (eg, local acceptance for wind power) and public–private partnerships can be imp

Experiences of relocation in dementia care from the perspective of six care workers.

Experiences of relocation in dementia care from the perspective of six care workers. International Journal of Older People Nursing6, 93-101 doi: 10.1111/j.1748-3743.2010.00246.x Background. Relocation of persons with dementia might be considered when quality of care cannot be sustained due to increasing needs. Relocation has been studied from the aspects of mortality and morbidity. Aim. To explore

Malignancies among women who gave birth after in vitro fertilization.

BACKGROUND Relatively few studies published to date have investigated IVF and cancer risk. In this study we compared the occurrence of cancer in women who gave birth after IVF with all other women who gave birth in the study period. METHODS All women who were treated with IVF and gave birth during the years 1982-2006 in Sweden were identified from all IVF clinics, and the occurrence of cancer in t

Mast cells reduce survival of myenteric neurons in culture.

Mast cell-nerve interactions play a key role in intestinal inflammation and irritable bowel disease. Loss of enteric neurons has been reported in inflammatory conditions but the contribution of mast cells in this event is unknown. To study neuronal survival and plasticity of myenteric neurons in contact with mast cells a co-culture system using myenteric neurons from rat small intestine and perito

Comprehensive cardiovascular risk management--what does it mean in practice?

The continued movement away from the treatment of individual cardiovascular (CV) risk factors to managing overall and lifetime CV risk is likely to have a significant impact on slowing the rate of increase in cardiovascular disease (CVD). However, the management of CVD is currently far from optimal even in parts of the world with well-developed and well-funded healthcare systems. Effective impleme

Accumulating mitochondrial DNA mutations drive premature hematopoietic aging phenotypes distinct from physiological stem cell aging.

Somatic stem cells mediate tissue maintenance for the lifetime of an organism. Despite the well-established longevity that is a prerequisite for such function, accumulating data argue for compromised stem cell function with age. Identifying the mechanisms underlying age-dependent stem cell dysfunction is therefore key to understanding the aging process. Here, using a model carrying a proofreading-

Large-scale Multiconfiguration Hartree-fock and Configuration-interaction Calculations of Isotope Shifts and Hyperfine Structures In Boron

A new isotope shift program, part of the multiconfiguration Hartree-Fock (MCHF) atomic structure package, has been written and tested. The program calculates the isotope shift of an atomic level from MCHF or configuration-interaction (CI) wave functions. The program is specially designed to be used with very large CI expansions, for which angular data cannot be stored on disk. To explore the capac
