In order to verify the frequency of human brucellosis among a TB suspected population, a study was conducted on the basis of sero-diagnosis of a total of 229 blood samples from TB suspected patients. Serological tests carried out were slide and semi-quantitative agglutination tests. Of the tested samples, 44 (19.21%) were SAT positive and of these, 28 (12.23%) were positive for the semiquantita...
dendrimer synthesis strategies now provide virtual control of macromolecular nanostructures as a function of size and surface/interior functionality. these strategies involve the covalent assembly of hierarchical components reactive monomers , branch cells or dendron’s around atomic or molecular cores according to divergent/convergent dendrite branching principles.combinon of two or more dendri...
