Defective oligodendrocyte development and severe hypomyelination in PDGF-A knockout mice.

There is a class of oligodendrocyte progenitors, called O-2A progenitors, that is characterized by expression of platelet-derived growth factor &agr;-receptors (PDGFR(&agr;)). It is not known whether all oligodendrocytes are derived from these PDGFRalpha-progenitors or whether a subset(s) of oligodendrocytes develops from a different, PDGFR alpha-negative lineage(s). We investigated the re

The HeartShield Device Reduces the Risk for Right Ventricular Damage in Patients With Deep Sternal Wound Infection.

Right ventricular rupture, resulting in serious bleeding, is a life-threatening complication associated with negative-pressure wound therapy (NPWT) in cardiac surgery. The use of a rigid barrier between the heart and the sharp sternal edges has been successfully tested on pigs. In the present article, we demonstrate increased safety in NPWT through the use of the HeartShield device.

Activation of G protein-coupled receptor 30 modulates hormone secretion and counteracts cytokine-induced apoptosis in pancreatic islets of female mice.

The role of the newly discovered estrogen receptor GPR30 in islet physiology and pathophysiology is unclear. We examined GPR30 expression in relation to hormone secretion and possible anti-apoptotic effects in isolated mouse islets using the synthetic GPR30 ligand G-1. The mRNA and protein expression of GPR30 was analyzed by qPCR, Western blot and confocal microscopy. Hormone secretion and cAMP co

The impact of social capital on changes in smoking behaviour: a longitudinal cohort study.

Background: Smoking prevalence across high-income countries such as the United Kingdom has significantly decreased over the past few decades; this decrease, however, has not occurred uniformly across social strata. The highest concentrations of smokers are currently found in lower-income groups. Lack of access to material resources and differing social norms have been cited as possible causes of t

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

High Plasma Levels of Galectin-3 Are Associated with Increased Risk for Stroke after Carotid Endarterectomy.

Galectin-3 (Gal-3) has been suggested to have both pro- and anti-atherogenic properties. High plasma Gal-3 levels are associated with increased risk for cardiovascular (CV) death. However, it has so far not been investigated if plasma Gal-3 levels can predict the risk for future stroke in patients suffering from carotid atherosclerosis. The aim of this study was to investigate whether Gal-3 could

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

Spinal cord injury - scientific challenges for the unknown future.

The history of spinal cord injuries starts with the ancient Egyptian medical papyrus known as the Edwin Smith Surgical Papyrus. The papyrus written about 2500 B.C.by the physician and architect of the Sakkara pyramids Imhotep, describes "crushed vertebra in his neck" as well as symptoms of neurological deterioration. An ailment not to be treated was the massage to the patients at that time. This f

Environmental Philosophy in Christianity and Buddhism: Meeting Places for a Dialogue

Questions concerning the human–nature relationship have received attention both within contemporary Christianity and Buddhism. Since the twentieth century an interesting and fruitful dialogue has been going on between the two religions. This article describes and discusses possible themes for a Buddhist–Christian dialogue on issues of environmental philosophy. The theoretical starting-point is the

Moisture conditions in cavity walls with wooden framework

The value of the air space in a cavity wall is discussed and examples of the moisture content in the masonry with different thicknesses of the insulation and width of the air space are illustrated as well as examples of how different measures affect the humidity in the inner parts of the insulation when a cavity wall is exposed by sunshine after heavy driving rain.

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

Everyday experience of families three years after diagnosis of type 1 diabetes in children: a research paper.

The purpose of this study was to illuminate the everyday experience of family members 3 years after a child had been diagnosed as having Type 1 diabetes. Qualitative interviews were conducted with 35 family members in 11 families and analyzed using a content analysis. The results were identified as eight categories describing the family member's everyday experiences: (a) knowledge and tried experi

Explaining Modes of Participation. A Dynamic Test of Alternative Rational Choice Models

Rational choice accounts of political participation identify two major solutions to “the paradox of participation” — collective incentives and selective incentives. Prior findings regarding the viability of these solutions are seemingly inconclusive and contradictory. In our view, one important reason for this is that the applicability of these solutions varies across participatory modes. In this

Pressure transduction to the thoracic cavity during topical negative pressure therapy of a sternotomy wound.

The present study was performed to examine pressure transduction to the thoracic cavity during topical negative pressure (TNP) therapy of a sternotomy wound. Seven pigs underwent median sternotomy. Pressure transduction catheters were placed on the anterior surface of the heart (under the foam), in the pericardium (under the heart), in the left pleura and in the oesophagus at the level of the hear
