Detection of sarcolectin-specific receptors like the cytokine macrophage migration inhibitory factor in rheumatoid nodules migration inhibitory factor in rheumatoid nodules
The objective of this study was the
evaluation of the relation between the N-acetylneuraminic
acid-binding endogenous lectin sarcolectin
and the cytokine macrophage migration inhibitory factor
(MIF) during development of rheumatoid nodules (RN)
in seropositive rheumatoid arthritis (RA). Sarcolectin
was purified and biotinylated. The binding patterns of
this probe were analyzed in RN from patients with RA
(n=23) and compared with the distribution of antibodies
with specificity for MIF, fibrin, fibronectin. In early RN,
all areas of the inflammatory tissue displayed presence
of receptors for sarcolectin. Macrophages were
especially positive. In mature rheumatoid nodules
binding of sarcolectin was restricted to the periphery of
necrotic areas, to endothelial cells and perivascular
connective tissue of marginal zones. Distribution
patterns of MIF were similiar but not identical. The
histological staining characteristics demonstrate
sarcolectin-binding receptors in RN that are altered upon
disease progression. The finding suggests that specific
interactions between this endogenous lectin and MIF
may be involved in the course of RA
Atmosphaeres – 360° Video Environments for Stress and Pain Management
The Atmosphaeres project aims to reduce sufferers’ stress and pain levels by using 360° video environments that are presented in a highly immersive Head-Mounted Display (HMD). Here we report first insights of our prototype combination of the 360° video environments and the Oculus Rift, the HMD used for our project. We find that our ‘Atmosphaeres’ are capable of truly transporting the user to another, virtually created location, however, there were a number of restrictions with the first system, including image quality and nausea which we hope to eliminate with the system we present in this paper. There are also a number of research questions that need to be considered for the use of the Atmosphaeres in stress and pain management or for general relaxation purposes. These questions include whether 360° video environments are capable of reducing stress and experienced pain and whether changes to the Oculus Rift DK2 do in fact reduce the nausea that was often caused by the DK1. Sound is another important yet often under-considered factor in many Virtual Reality applications and questions we seek to answer revolve around how the quality and type of audio contribute to users’ feeling of presence and ultimately their stress and pain levels
