Functional importance of estrogen receptors in the periodontium.

The main functions of estrogen are associated with reproduction. However, estrogen has been shown to be of functional importance also in non-classic target organs. Previous studies, especially epidemiologic and clinical ones, have addressed estrogen's influence on periodontitis, suggesting that estrogen has a beneficial effect, but the biological mechanisms have not been identified. Estrogen exert

Nitric oxide-producing cells project from retinal grafts to the inner plexiform layer of the host retina

PURPOSE: Amacrine cells expressing nitric oxide synthase (NOS) are seen in normal retinas and retinal grafts to extend long processes, which can be followed for long distances. Taking advantage of the morphologic features of these cells, the present study examined whether graft-host connections involve cells capable of producing nitric oxide, a recognized retinal neuromodulatory compound.METHODS:

Maternal morbidity and mortality in in-vitro fertilization.

Pregnancies following in-vitro fertilization (IVF) are known to be at increased risk of a number of pregnancy- and delivery-related complications when compared with non-IVF pregnancies. Most of these complications seem to be due to underlying fertility problems. Ovarian stimulation carries a marked risk for two serious conditions - ovarian torsion and ovarian hyperstimulation syndrome - both of wh

On-line Heart Rate Monitoring Using the Extra-corporeal Pressure Sensors of a Dialysis Machine

Heart rate can be extracted from the extracorporeal venous pressure signal of a dialysis machine. The results are of comparable accuracy and reliability to the ones obtained by the PPG reference signal from a pulse oximeter. Difficulties that occur during heart rate estimation were determined, and some can be overcome by a slight adjustment of blood flow rate. The described techniques, after being

Elastin- and Collagen-Rich Human Carotid Plaques Have Increased Levels of the Cysteine Protease Inhibitor Cystatin C.

Background: Cystatin C is a major inhibitor of the elastin- and collagen-degrading cysteine proteases and may therefore have an important role in preserving atherosclerotic plaque stability. In this study we analyzed the associations between human carotid plaque cystatin C expression and the plaque content of collagen and elastin. Methods: Thirty-one plaques were removed by endarterectomy and homo

Riskabelt att skapa låtsasmarknader i välfärden

Vinsterna bland företagen i välfärdssektorn kan bara hämtas hem genom att krympa kostnaderna. Men att låta företag agera på låtsasmarknader, där nedskärningar är det enda sättet att gå med vinst på kort sikt, är en riskabel väg i välfärdsbyggandet.

An Innovative Systems Approach for Research on Urban Risk Reduction and Climate Change Adaptation

This paper presents an innovative research on urban risk reduction and climate change adaptation that combines case studies, grounded theory and systems analysis, which could be used as a template for similar intersectoral and interdisciplinary investigations. Such a ‘case studies–grounded theory–systems analysis approach’ permits a grounded theory to be built from case study data, which is viewed
