Evaluation of an Immunochromatographic Point-of-Care Test for the Simultaneous Detection of Nontreponemal and Treponemal Antibodies in Patients With Syphilis

We described the evaluation of the Syphilis Screening & Confirm Assay for the simultaneous detection of nontreponemal and treponemal antibodies. A total of 248 samples were evaluated. The sensitivity of the tests was 98.8%, 99.5% and 98.9%, while specificity was 94.7%, 88.9% and 93.2%, respectively, as compared with the rapid plasma reagin, Treponema pallidum hemagglutination assay, and fluorescent treponemal antibody absorption tests.

Probing the aurone scaffold against Plasmodium falciparum: Design, synthesis and antimalarial activity

A library comprising 44 diversely substituted aurones derivatives was synthesized by straightforward aldol condensation reactions of benzofuranones and the appropriately substituted benzaldehydes. Microwave enhanced synthesis using palladium catalyzed protocols was introduced as a powerful strategy for extending the chemical space around the aurone scaffold.

Development of a monoclonal antibody TAS-ELISA assay for detection of Phaeomoniella chlamydospora

A monoclonal antibody-based triple antibody sandwich (TAS) enzyme-linked immunosorbent assay (ELISA) was developed to specifically detect Pa. chlamydospora from grapevine wood tissues. This assay could be especially useful for large-scale application in nurseries, to ensure Pa. chlamydospora-free grapevine stocks, and thus contributing to the production of healthy propagation material.

Prominent intraspecific genetic divergence within Anopheles gambiae sibling species triggered by habitat discontinuities across a riverine landscape

The Anopheles gambiae complex of mosquitoes includes malaria vectors at different stages of speciation, whose study enables a better understanding of how adaptation to divergent environmental conditions leads to evolution of reproductive isolation. We investigated the population genetic structure of closely related sympatric taxa that have recently been proposed as separate species (An. coluzzii and An. gambiae), sampled from diverse habitats along the Gambia river in West Africa.
