MALDI-TOF-MS was used for the first time as a direct screening method to analyse sponge tissue (Stylissa caribica). In order to validate this method the results were compared with a HPLC-ESI-MS analysis of the crude extract from the investigated sponge. Both methods showed a good agreement in their results, allowing for the rapid identification of 15 pyrrole-imidazole alkaloids.

Abstract. The management of vascular emergencies is dependent on rapid identification and confirmation of the diagnosis with concurrent patient stabilization prior to immediate transfer to the operating suite. A variety of technological advances in diagnostic imaging as well as the advent of minimally invasive endovascular interventions have shifted the contemporary treatment algorithms of such pathologies. This review provides a comprehensive discussion on the current state and future trends in the management of ruptured abdominal aortic aneurysms as well as acute aortic dissections.

Lc50 Value

Study to assess the larvicidal property of Lantana camara leaves against Aedes triseriatus larvae found that the ethyl acetate extract had profound larvicidal action with the crude extract having a LC50 value of 409.831ppm. GC-MS analysis of the ethyl acetate extract confirmed the presence of twenty-one compounds out of which beta-caryophyllene covered the highest percentage of the chromatogram area. Further tests with beta-caryophyllene against the mosquito larvae proved it to be the active ingredient of L. Camara with a LC50 value of 104.243ppm.
