noscopy showed diffuse mucosal edema through the entire colon, with multiple reddish erosions and contact bleeding (Fig. A). On colonoscopic biopsy, homogenous amyloid deposits were seen in the parenchyma and vessels (Fig. B, H&E, ×200), and Congo red staining for the amyloid, coupled with polarized light, demonstrated the characteristic apple-green birefringence (Fig. C, Congo red, ×400).

Umbilical cord blood (UCB) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (HSCs). Because of insufficient number of cord blood CD34+ cells, the expansion of these cells seems to be important for clinical application. Mesenchymal stromal cells (MSCs), playing an important role in HSCs maintenance, were used as feeder layer. Apo...

Background: Intraventricular hemorrhage (IVH) is one of the most serious complications of premature deliveries, especially in very low birth weight (VLBW) newborns. The current study compared the number of nucleated red blood cells (NRBCs) in newborns with and without IVH.Methods: This cross-sectional study was carried out on 109 VLBW neonates who were referred to the Neonatal Intensive C...

The newly developed XE-2100 haematology analyser can provide complete blood counts, leukocyte differentials, perform reticulocyte analysis, and obtain quantitative data on nucleated red blood cells (NRBCs). In this study, we evaluated the basic performance of this instrument using routinely obtained blood specimens treated with ethylenediaminetetraacetic acid-2K. Reproducibility, carryover, sta...
