Historically, humans have managed food systems to maximize productivity. This pursuit has drastically modified terrestrial and aquatic ecosystems globally by reducing species diversity and body size while creating very productive, yet homogenized, environments. Such changes alter the structure and function of ecosystems in ways that ultimately erode their stability.

This injury predominantly affects individuals in their youth and middle age. In this case series, we describe three middle-aged men with neglected insertional Achilles tendon ruptures, each presenting an average 10 cm defect.

The results of extended X-ray absorption fine structure (EXAFS) experiments on NapA support an oxidized Mo(VI) hexacoordinate active site coordinated by a single terminal oxo donor, four sulfur atoms from two separate pyranopterin dithiolene ligands, and an additional S atom from a conserved cysteine amino acid residue. We found no evidence of a terminal sulfido ligand in NapA.
