Five-membered rings are of particular interest, due to their presence in some of the most common molecules in chemistry and biology. Despite their apparent simplicity, the structural resolution of these rings is complex, due to their inherent conformational flexibility. Here, we describe an application of a recently reported simple and efficient NMR protocol based on the measurement of spin-spi...

In the present study, a total of ten seaweed species collected from the Kollam coast (Indian ocean) were subjected to antifouling assays against the common fouling organisms such as Balanus amphitrite, Mytilus edulis and three biofilm forming bacteria, Vibrio sp., Colwellia sp. SW125 and Pseudoalteromonas sp. SW124. Of all the seaweeds tested, only one species, the red algae, Laurencia brandeni...

Aqueous and organic extracts of twenty-seven species of marine algae (14 species of Rhodophyta, 5 species of Phaeophyta and 8 species of Chlorophyta) collected from the Gulf of Mexico and Caribbean coast of the Yucatan Peninsula (Mexico) were evaluated for their antileishmanial in vitro activity against Leishmania mexicana promastigote forms. The cytotoxicity of these extracts was also assessed...

During May 2009 and July 2011, we collected 357 mammals and examined each for ectoparasites. Among the ectoparasites collected, a new species of flea was discovered. This new species, Lentistivalius philippinensis, is described from the male sex only. Two males were recovered from two specimens of the soricid Crocidura grayi Dobson in Municipality Maria Aurora, Aurora Province, Luzon, Philippin...
