Effect of motions in prominences on the helium resonance lines in the extreme ultraviolet [PDF]

, 2006
<b>Context</b>: Extreme ultraviolet resonance lines of neutral and ionised helium observed in prominences are difficult to interpret as the prominence plasma is optically thick at these wavelengths. If mass motions are taking place, as is the

A multi-viewpoint comparison of the velocity field of propagating coronal disturbances

Astronomy & Astrophysics
Small-scale propagating disturbances (PDs) are ubiquitous in the solar corona. The method called time-normalised optical flow (TNOF) was developed for mapping PDs velocity fields in time series of extreme-ultraviolet (EUV) images.

Classical Complement Pathway Inhibition in a Pediatric Patient With Refractory Immune Thrombocytopenia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...

Dynamic disappearance of prominences and their geoeffectiveness [PDF]

Geofísica Internacional, 2008
We study 14 cases of dynamic “disparition brusque” (DBd), the sudden disappearance of quiescent filaments/prominences, during two solar minima: 1985-1986 and 1994.

Coronal mass ejection plasma diagnostics using Metis coronagraph

Astronomy & Astrophysics
Context. We investigate the physical conditions of erupting prominences embedded in coronal mass ejection (CME) cores. Aims. The physical parameters of interest were derived by combining the hydrogen Lyman α (Lα) and visible-light (VL) images ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Prominences and magnetic activity on young single and binary stars [PDF]

, 2008
In this thesis I study the magnetic activity of young stars via observations of stellar prominences on single stars and by applying the Zeeman Doppler imaging (ZDI) technique to map the magnetic fields and measure differential rotation of a young binary ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Analyses on Wassenius’s Report for Total Solar Eclipse in 1733: Quantifications of the Solar Radius and the Earliest Reported Prominences

The Astrophysical Journal
Total solar eclipses (TSEs) offer a unique opportunity to observe the solar atmosphere, detect limb phenomena, and accurately measure the solar radius.
