viral symptoms indicative of iris yellow spot virus (iysv) were observed on onion in several fields near chenaran in khorasan razavi province. mechanical inoculation of herbaceous hosts with onion sap extracts from symptomatic plants showed similar symptoms to those described for iysv. the mechanically transmitted virus reacted only with antisera specific to iysv in das-elisa but not with antis...

As established by Eldering et al. (3), fimbrial antigens of Bordetella pertussis cells were used to raise agglutinating antibodies and have thus been called agglutinogens, which are constitutive parts of two fimbrial proteins, Fim2 and Fim3, and of an outer membrane protein called pertactin (Prn), respectively (1, 2). On the basis of this, monoclonal antibodies to Fim2 and Fim3 were obtained (4...

The purpose of this study was to survey infections with Salmonella spp. in poultry flocks in the vicinity of Tehran and to determine the most frequent serogroups and serotypes implicated. Twenty-eight samples of pullet, layer, and broiler flocks were randomly collected (n=1463), including freshly dropped feces from live birds or visceral organs from dead birds. In most flocks, 60 samples were t...

In [2], Alexeev constructed a proper moduli space of polarized toric varieties. However, in addition to the main component containing the toric varieties, there were additional irreducible components which were tricky to eliminate in a canonical way. Later, Olsson [1] showed how adding a log structure to the toric varieties under consideration effectively restricted the problem enough to single...

We construct endomotives associated to toric varieties, in terms of the decomposition of a toric variety into torus orbits and the action of a semigroup of toric morphisms. We show that the endomotives can be endowed with time evolutions and we discuss the resulting quantum statistical mechanical systems. We show that in particular, one can construct a time evolution related to the logarithmic ...

The immunochemical properties of chromatographically prepared human erythrocuprein differ from those of the chloroform-ethanol-treated protein. Losses of copper also appear to modify its immunochemical reactivity. The result of the immunochemical reactions of rabbit antibody to human erythrocuprein with human liver and brain extracts suggests a common antigen in the two tissues. Human erythrocy...
