Osteoarthritis: what we have been missing in the patellofemoral joint.

Patellofemoral osteoarthritis is common clinically and often independent of tibiofemoral disease. Intriguingly, the patella demonstrates more severe degeneration earlier in the disease process compared with the juxtaposed femoral groove. Here, we consider three hypotheses influencing this disparity and thus discover crucial insights into the etiology of osteoarthritis.

ACL stability, function, and arthritis: what have we been missing?

Depression in Diabetes: Have We Been Missing Something Important?

An extensive literature has developed to suggest that depression is more common in patients with diabetes than in the general population (1) and is associated with chronic hyperglycemia (2), risk for diabetes complications (3), and mortality (4). Although the causal linkages among these relationships have not been demonstrated, their consistency has led to calls for intensive efforts to identif...

Flavor - singlet hybrid baryons may already have been discovered

The splittings between the spin 1/2 and spin 3/2 iso-singlet baryons Λs(1405) and Λs(1520), and their charmed counterparts Λc(2593) and Λc(2625), have been a theoretical conundrum. Here we investigate the possibility that the QCD binding of color octets comprised of three quarks in a flavor singlet configuration is stronger than previously envisaged, allowing these states to be interpreted as h...
