This chapter presents how well known bioinformatics resources can be described as search services in the search computing framework and how integrated analyses over such services can be carried out. An initial set of bioinformatics services has been described and registered in the search computing framework and a bioinformatics search computing (Bio-SeCo) application using these services has be...

Salvia is one of the famous genera of the family Lamiacea previously called Labiatae comprising about 800 species throughout the world [1]. Most of the members of this genus are known due to their biologically active chemical constituents specifically reported for anti-tumor activity [2]. A number of Salvia species are used in folk medicines. For example, S. cavaleriei is used for the treatment...

El presente estudio tuvo como objetivo principal la cuantificación de sesquiterpenlactonas presentes en los extractos cloro fórmicos secos hojas Calea urticifolia “Juanislama”, recolectadas bimensualmente durante el año 2012. Los metabolitos secundarios se extrajeron por medio del método Soxhlet usando cloroformo solvente; llevó a cabo identificación cromatografía capa fina con reactivo Baljet ...

The isolation, identification and total synthesis of two plant-derived inhibitors of the NF-κB signaling pathway from the iso-seco-tanapartholide family of natural products is described. A key step in the efficient reaction sequence is a late-stage oxidative cleavage reaction that was carried out in the absence of protecting groups to give the natural products directly. A detailed comparison of...

In recent years, school strikes and street protests for climate justice have drawn international attention to young people's mobilisation activism on global issues. This article addresses the need map history of awareness among people by exploring origins Operation Dagsverke (Operation Day's Work) campaign in Sweden during early 1960s. Drawing primarily material from student-led council organis...
