Are amplitude and strength of muscle contraction reduced in experimental tears of the rotator cuff?
Chronic tendon tears are associated not only with retraction, fatty infiltration, and atrophy but also with loss of strength and contractile amplitude. The functional changes can only indirectly and approximately be predicted by computed tomography imaging findings.
Plasma NGAL is a novel marker of kidney function, which correlates to duration of end-stage renal failure (ESRD) and serum creatinine in uraemic patients awaiting kidney transplantation. Plasma NGAL is associated with homocysteine in transplanted patients. The prognostic value of these findings requires further studies.
