1. The resting electrocardiogram was obtained from 25 Trypanosoma cruzi-infected rats 30 days after infection (phase I). The resting electrocardiogram was abnormal in 12 (group I) and normal in 13 (group II) animals. Nineteen similar but non-infected animals served as controls. Both the resting electrocardiogram and the ajmaline test were performed 120 and 350 days after infection (phases II an...

Knowledge Bases and Related Tools (KBART) is one of the most successful National Information Standards Organization (NISO) recommended practices. Formally supported by over eighty organizations across all stakeholder groups, it enables a standardized transfer data between content providers knowledgebases. The KBART Standing Committee has begun work on Phase III KBART, which was last updated in ...

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.
