Apotransferrin (apo Tf)  in 0.1 M N-(2hydroxyethyl)piperazine-N2-ethanesulfanic acid at 25 ˚C  and pH 7.4 has been titrated with acidic solution of Tb3+. The binding of Tb3+ at  the two specific metal-binding sites of transferrin was followed from the changes in the difference UV spectra at 245 nm. The molar absorptivity per binding site for Tb3+...

Iron-containing proteins catalyze lipid peroxidation when combined with either H2O2 or ascorbic acid (ASC). Microsomal membranes were prepared from Day 13 endometrial and conceptus tissues (5 pigs) and from Day 30 endometrial, placental, fetal liver, and fetus minus fetal liver tissues (5 pigs). Microsomal membranes were subjected to the following in vitro treatments: 1) no treatment, 2) 50 mic...

Iron-transferrin (FeTF) is an essential growth factor required for proliferation of lymphoid cells. FeTF activates protein kinase C (PKC) in the lymphoblastoid T-cell line, CCRF-CEM. We have treated CEM cells with human FeTF, then examined levels of PKC mRNA by hybridization analysis using cDNA probes specific for alpha-, beta-, and gamma-PKC subspecies. CEM cell mRNA hybridized with the beta-s...

Pediatric Traumatic Brain Injury (TBI) is a significant problem that affects many children each year. Progress is being made in developing neuroprotective strategies to combat such injuries; however, investigators are a long way from therapies to fully preserve injured neurons and glia. To restore neurological function, regenerative strategies will be required. The Subventricular Zone (SVZ) har...
