Global Surgery – Redirecting Strategies for a Global Research Agenda; Comment on “Global Surgery – Informing National Strategies for Scaling Up Surgery in Sub-Saharan Africa”

More than three years have passed since the publication of the Lancet Commission on Global Surgery and its recommendations on scaling up surgery in sub-Saharan Africa (SSA). An important gap, the voice of the districts as well as lack of contextualized research, has been noted in its support of national surgical plans that run the risk of being at best, aspirational. Moreover, a ‘one-size-fits-...

Applications of Cell Therapy in Vascular Surgery

Trying to use embryonic stem cells about 20 years ago, working with animals,  especially rats began. During these years , many experiments in mouse embryonic stem cells to transform into a variety of cells and transplanting them were led to remarkable success . In the next issue of human stem cells were considered successful until finally in 1998 the first report was published in the proliferat...

Progress in Global Surgery; Comment on “Global Surgery – Informing National Strategies for Scaling Up Surgery in Sub-Saharan Africa”

Impressive progress has been made in global surgery in the past 10 years, and now serious and evidence-based national strategies are being developed for scaling-up surgical services in sub-Saharan Africa. Key to achieving this goal requires developing a realistic country-based estimate of burden of surgical disease, developing an accurate estimate of existing need, deve...

Global Alliance Partition in Trees

Let G be a connected graph with vertex set V (G) and edge set E(G). A (defensive) alliance in G is a subset S of V (G) such that for every vertex v ∈ S, |N [v]∩S| ≥ |N(v)∩(V (G)− S)|. The alliance partition number, ψa(G), was defined (and further studied in [11]) to be the maximum number of sets in a partition of V (G) such that each set is a (defensive) alliance. Similarly, ψg(G) is the maximu...
