Nucleolin and NO38 are abundant nucleolar proteins implicated in the transcription and processing of ribosomal RNA, and in the packaging and transport of ribosomal proteins or preribosomal particles (for references see 1-5). cDNAs encoding the chicken homologs of these proteins were cloned (by lmmunoscreening; 6) from Xgtll cDNA expression libraries prepared from poly(A)+ RNA of 10 day old chic...

Previously we observed that sera from recipients of allogeneic bone marrow transplants who developed extensive chronic graft-versus-host disease (GVHD) intensively stained the nucleolar region of target cells in indirect immunofluorescence microscopy. To identify the target antigens, immunoblotting experiments were performed using isolated nuclei, isolated nucleoli, and purified nuclear and nuc...

Using bank level data this paper examines how bank’s specific characteristics and the overall banking environment affect the profitability of commercial domestic and foreign banks operating in the 15 EU countries over the period 1995–2001. The results indicate that profitability of both domestic and foreign banks is affected not only by bank’s specific characteristics but also by financial mark...

Inter-colonial aggression was tested using three colonies of Scaptotrigona bipunctata in a natural setting when their nests were moved and by artificial contact between individuals. Examination of the cuticular lipids of individuals from two colonies kept under identical conditions showed clear differences in their cuticular hydrocarbon profiles. The cuticular lipids were a mixture of hydrocarb...

The conventional Sargan (1958) / Hansen (1982) test of overidentifying restrictions and the Tilting Parameter test of Imbens, Spady and Johnson (1998) are compared in the context of the AR(1) dynamic panel data model using Monte Carlo experiments. Interestingly, the size properties of the former are found to be superior in this setting. Nevertheless, the Sargan / Hansen test is found to have no...

A Colombian strain of Trypanosoma rangeli was characterized by analyzing its behaviour in different axenic and cellular culture, its infection rate and the histopathological lesions produced in experimental animals. Although slight inflammatory infiltrations were shown in different histopathological sections, no pseudocysts could be observed. Grace's insect medium is better than liver infusion ...

This paper investigates empirically the relationship between the pattern of fiscal policy and the demand for international reserves in developing countries, and how this relationship is associated with political risk and conditional access to global capital markets. It finds evidence that for developing countries with low political risk, countercyclical (procyclical) fiscal policies are associa...
