background: leishmania homologue of receptors for activated c kinase(lack) antigen is a 36-kda protein, which provokes a very early immune response against leishmania infection. there are several reports on the expression of lack through different life-cycle stages of genus leishmania , but only a few of them have focused on l.tropica . methods: the present study provides details of the cloning...

objective: leishmaniasis is caused by parasitic protozoa of the genus leishmania which in the infected host is obligate intracellular parasite. lack gene is conserved among related leishmania species. lack is the immuno-dominant antigen of l.major which is considered as the most promising molecule for a recombinant or dna vaccine against leishmaniasis. materials and methods: in this study the ...

This paper builds a bridge between research on regulatory focus in motivation and classification learning. It tests the hypothesis that a fit between the situational regulatory focus and the reward structure of the task leads to greater cognitive flexibility than a mismatch between situational focus and the reward structure and that the fit between the regulatory focusinduced processing charact...

Let X,, , X, be a sequence of independent and identically distributed random variables with an unknown underlying continuous cumulative distribution function F. Relative to this unknown distribution function suppose one would like to test a null hypothesis concerning the goodness of fit of F to some distribution function using symmetric functions of sample spacings. In some applications the nul...

MESERVEY, R., 1971. The coastline fit of Africa and South America. Palaeogeography, Palaeoclimatol., Palaeoecol., 9: 233-243. It has become axiomatic that the pre-drift reconstruction of Africa and South America is to be made by fitting together the continental shelves. Although this procedure is very plausible, actually the detailed fit of the coastlines is better than that of the shelves and ...

background : there are several methods, such as vaccination, to control visceral leishmaniasis. although there is no efficient vaccine, it seem dna vaccination with stimulates both cellular and humoral immunity apparently is the best way. the aim of this study was cloning and expression of lack gene, a 36kd protein, as a can-didate protein for vaccination against iranian l.infantum. methods: ir...
