Commentary: MAGA: Multiple arterial grafting agony

Multiple arterial grafting and ostriches: let’s all take heart!

MS-1 magA

Bacterial genes involved in the biomineralization of magnetic nanoparticles in magnetotactic bacteria have recently been proposed as reporters for magnetic resonance imaging (MRI). In such systems, the expression of the bacterial genes in mammalian cells purportedly leads to greater concentrations of intracellular iron or the biomineralization of iron oxides, thus leading to an enhancement in r...

Arterial bypass grafting of the coronary circulation

Surgical coronary bypass has evolved continually, and recent developments favor performing coronary grafts with all-arterial conduits in order to obtain better long-term graft patencies. With bilateral internal mammary artery grafts and both radial arteries, four excellent arterial conduits exist for revascularization of the majority of multivessel disease patients, including those with valve d...

Faster way to agony

Many real-world phenomena exhibit strong hierarchical structure. Consequently, in many real-world directed social networks vertices do not play equal role. Instead, vertices form a hierarchy such that the edges appear mainly from upper levels to lower levels. Discovering hierarchies from such graphs is a challenging problem that has gained attention. Formally, given a directed graph, we want to...

The BMA in agony.

The BMA suffered agonies last week. And the chairman of its council, Dr Jeremy Lee-Potter, suffered even more. Why the agony and will anything be learnt? Even before the annual representative meeting (the supreme policy making body of the association) had opened in Inverness last week a whispering campaign had begun. It said that Dr Lee-Potter (attending his first such meeting as chairman of co...
