A similarity measure is described that does not require the prior specification of features or the need for training sets of representative data. Instead large numbers of features are generated as part of the similarity calculation and the extent to which features can be found to be common to pairs of patterns determines the measure of their similarity. Emphasis is given to salient image region...

In this paper we report on an ongoing statistical analysis of actual CCSN traffic data. The data consist of approximately 170 million signaling messages collected from a variety of different working CCS subnetworks. The key findings from our analysis concern: (1) the characteristics of both the telephone call arrival process and the signaling message arrival process, (2) the tail behavior of th...

The adoptive transfer of antigen-specific CD8+ T cells is a promising approach for the treatment of chronic viral and malignant diseases. In order to improve adoptive T cell therapy (ATT) of cancer, recent strategies aim at the antibody-based blockade of immunosuppressive signaling pathways in CD8+ T cells. Alternatively, adjuvant effects of immunostimulatory cytokines might be exploited to imp...

Presented here are femtosecond pump-probe studies on the water-solvated 7-azaindole dimer, a model DNA base pair. In particular, studies are presented that further elucidate the nature of the reactive and nonreactive dimers and also provide new insights establishing that the excited state double-proton transfer in the dimer occurs in a stepwise rather than a concerted manner. A major question a...

High performance liquid chromatography (HPLC) was used to follow the kinetics of the alkaline induced opening of the imidazole ring of 7-methyl-guanosine (7-meGuo). The kinetics show an initial rapid formation of a major transient intermediate and some minor products that were chromatographically separable into seven peaks. This phase of the reaction is followed by the formation of a dominant p...

IL-7 was previously shown to upregulate the expression of molecules important for interaction of CD4+ T cells with B cells. It is poorly studied whether IL-7 has a role in the biology of T follicular helper (Tfh) cells and whether IL-7 dysregulates the expression of B-cell costimulatory molecules on Tfh cells. We review the literature and provide arguments in favor of IL-7 being involved in the...

The basidiomycete Lentinula edodes (Le.) cytochrome P450, Le.CYP1 was functionally expressed in Saccharomyces cerevisiae. The microsomal fraction containing Le.CYP1 was prepared from the recombinant yeast and the Le.CYP1 was analyzed. The 7-ethoxycoumarin and benzo(a)pyrene were found to be the substrates of Le.CYP1 enzyme. Le.CYP1 converted 7-ethoxycoumarin to 7-hydroxycoumarin.

Methanomicrobium mobile requires a heat-stable factor present in ruminal fluid and in boiled cell extract from Methanobacterium thermoautotrophicum for growth. By comparing the growth of M. mobile with boiled cell extract with that observed with various methanogenic cofactors, we found that 7-mercaptoheptanoylthreonine phosphate (HS-HTP) supported sustained growth of M. mobile, at an optimal co...

a potent antagonist of riboflavin in the rat, has been found to be nonspecific in the inhibition of the growth of Walker rat Carci noma 256. 7-Ethyl-8-methyl-10-(r-D-ribityl)isoalloxazine (7ethyl-8-methyIflavin) and 7-methyl-8-ethy 1-10-(1' -D-ribityl) isoalloxazine (7-methyl-8-ethylflavin) have been found to replace riboflavin for the growth of and the efficiency of utilization of food by the ...
