The soluble transferrin receptor (sTfR)-ferritin index is a potential predictor of celiac disease in children with refractory iron deficiency anemia.

abstract：:Microsatellite typing is frequently used in disease diagnosis and in genetic association studies. Inter-study consistency and comparability is essential in both applications. In this study, we show that the interlaboratory comparison of microsatellite sizes is often discrepant and misleading. This is a matter of great...

abstract：BACKGROUND:Cystatin C (CST3), a strong inhibitor of cysteine proteinases, is freely filtered by the kidney glomerulus and is reabsorbed by the tubules, where it is almost totally catabolized, with the remainder then eliminated in urine. In tubular diseases, it seems sensible to postulate that CST3 degradation would be ...
