A novel Mutein of TNFα Containing the Arg-Gly-Asp Sequence Shows Reduced Toxicity in Intestine
The effects of human tumour necrosis factor-α (TNFα), or its
mutein (F4168) having the cell adhesive Arg-Gly-Asp sequence at the
N-terminus, on intestinal injury, were examined. Histopathological
examination revealed that an intravenous injection of TNFα
resulted in marked haemorrhage or oedema in the caecum of rats,
whereas F4168 showed no such effects even at the same therapeutic
dose. Moreover, the number of neutrophils that adhered to
endothelial cells or infiltrated the mucosal tissue was much higher
after TNFα injection compared with F4168 in vivo.
The enhanced adhesion of neutrophils on to human umbilical vein
endothelial cells also occurred when the latter were pre-stimulated
with TNFα but not with F4168 in vitro. The
expression of the cell adhesion molecules including endothelial
leukocyte adhesion molecule-1 or intercellular adhesion molecule-1
on F4168- stimulated human umbilical vein endothelial ceils was
significantly lower than that stimulated with TNFα. These
results suggest that the Arg-Gly-Asp sequence introduced into the
TNFα molecule abrogates the side effect of this cytokine such
as tissue injury or shock, and that F4168 could be useful for
systemic therapy
Conceptual design of the liquid metal laboratory of the TECHNOFUSION facility
The application of liquid metal technology in fusion devices requires R&D related to many phenomena: interaction between liquid metals and structural material as corrosion, erosion and passivation techniques; magneto-hydrodynamics; free surface fluid-dynamics and any other physical aspect that will be needed for their safe reliable operation. In particular, there is a significant shortage of experimental facilities dedicated to the development of the lithium technology. In the framework of the TECHNOFUSION project, an experimental laboratory devoted to the lithium technology development is proposed, in order to shed some light in the path to IFMIF and the design of chamber's first wall and divertors. The conceptual design foresee a development in two stages, the first one consisting on a material testing loop. The second stage proposes the construction of a mock-up of the IFMIF target that will allow to assess the behaviour of a free-surface lithium target under vacuum conditions. In this paper, such conceptual design is addressed
Toroidal flow measurements of impurity ions in QUEST ECH plasmas using multiple viewing chords emission spectroscopy
A spectroscopic system with multiple viewing chords was developed for QUEST (Q-shu University Experiment with Steady-State Spherical Tokamak) to measure the spatial distribution of ion toroidal velocities in discharges sustained by electron cyclotron resonance heating (ECH). Twenty-four viewing chords were aligned in the midplane and C III emission line spectra were measured for three types of ECH discharge under different magnetic field configurations. By applying an inversion method to the measured spectra, we evaluated the radial distributions of C2+ ion emissivity, temperature, and toroidal velocity. The error in the evaluated velocity was estimated to be less than 5 km/s. It was found that the velocity depends on the magnetic field configuration
