1069 T 1 / ST 2 - deficient Mice Demonstrate the Importance of T 1 / ST 2 in Developing Primary T Helper Cell Type 2 Responses
We have generated mice with a deficiency in T1/ST2 expression to clarify the roles of T1/ST2 in T helper cell type 2 (Th2) responses. Using immunological challenges normally characterized by a Th2-like response, we have compared the responses of T1/ST2-deficient mice with those generated by wild-type mice. Using a primary pulmonary granuloma model, induced with Schistosoma mansoni eggs, we demo...
متن کاملSome results on list T-colourings
In this paper we will give some results on list T-colorings. In particular we will give a lower bound for the T-choice number of even cycles with the set T = {0, 1,2 ..... r}, r ~> 1, and give the value of the T-choice number for the even cycles C4, and C2n where n>~r.
متن کاملAn Upper Bound for List T-colourings
Erdos, Rubin and Taylor showed in 1979 that for any connected graph G which is not a complete graph or an odd cycle, ch(G) < A, where A is the maximum degree of a vertex in G and ch(G) is the choice number of the graph (also proved by Vizing in 1976). They also gave a characterisation of Z)-choosability. A graph G is Z)-choosable if, when we assign to each vertex u o f G a list containing d(v) ...

The small separation of the individual stellar components in the TTau system has prevented spectroscopy of the individual components in the near-infrared (NIR) in the past. We present NIR data (Hand K-band) on this object taken using the ALFA adaptive optics (AO) system in combination with the 3D integral field spectrograph. Except for the Brackett series seen in emission, the NIR spectra of T ...

Observations of T Tauri stars and young brown dwarfs suggest that the accretion rates of their disks scale strongly with the central stellar mass, approximately Ṁ ∝ M ∗ . No dependence of accretion rate on stellar mass is predicted by the simplest version of the layered disk model of Gammie (1996), in which non-thermal ionization of upper disk layers allows accretion to occur via the magnetorot...
