Even if within-species HEG spread were possible for some reason, then escape from long-term degeneration would seem unlikely as one imagines horizontal transfer between metazoan germ-lines to be a prohibitively rare event.
One argument against tibiotalar arthrodesis is the frequently associated, long-term degeneration of the talonavicular joint, which can be attributed to changes in biomechanical stresses.
Axonal integrity is tightly coupled with myelin function as subtle changes in the molecular composition can result in mid- to long term axonal degeneration under otherwise physiological conditions (Griffiths et al., 1998; Garbern et al., 2002; Lappe-Siefke et al., 2003; Nave and Trapp, 2008).
In addition, long term protection from joint degeneration has not yet been demonstrated (Wirth et al. [2002]).
We hypothesize children with brachial artery repair are at long term risk of developing aneurysmal degeneration or Thrombosis thus necessitating annual duplex ultrasonography and physical examination.
This study reports an association between variation in the pain gene COMT and reduction in pain in patients with LBP and lumbar disc degeneration at long term follow-up.
High-dose ALN treatment was able to prevent early trabecular bone loss and cartilage degeneration following non-invasive knee injury, but was not able to mitigate long-term joint degeneration.
However, until now, the traditional surgical strategies have not been able to repair completely osteochondral lesions, but often produce a fibrous or fibrocartilaginous tissue that undergoes degeneration in the long term, with reduced biological, biomechanical and biochemical features [ 2].
In his opening remarks, Smith, the director of the players' union, did not directly take issue with the N.F.L.'s approach, although in the statement he filed with the committee he assailed the N.F.L. for "denigrating, suppressing and ignoring" research that has linked football concussions to long-term cognitive degeneration.
Subchondral perfusion of osteochondral grafts has been shown to be important in preventing long-term cartilage degeneration.
Therefore, there is the need for alternative animal models for GSD-1a for studying both long-term liver degeneration and long-term effects of new therapeutic approaches.
