The introduction of antigen into animals causes antigen-specific T cells to divide and then die. Activated T cell death requires either of the death effector molecules, Bak or Bax. When T cells die, Bak and Bax change their conformations, a phenomenon that is thought to be required for Bak or Bax to drive cell death. Here we show that Bak changes conformation before activated T cells die, as de...
This study compared the predictive value of the LIVE/DEAD fluorescence viability assay to xenotransplantation in SCID mice, regarding the developmental potential of cryopreseved human ovarian tissue for fertility preservation purposes. The thawed ovarian tissue of ten patients was partly examined by LIVE/DEAD viability staining or histologically examined after transplantation and gonadotropin s...
Background: Predictive value of the umbilical nucleated red blood cells (NRBCs) at birth for neonatal outcomes has been assessed. Hence, the present study was conducted to compare NRBC between discharged and dead neonates.Methods: This cross-sectional study was performed on preterm newborns with a birth weight of < 1,500 g admitted to the Neonatal Intensive Care Unit of Ghaem Hospital, Ma...
Streptomycin (100 micrograms per milliliter), desiccation (over CaSO(4)), and ultraviolet radiation (4500 microwatts per square centimeter at 254 nanometers for 15 minutes) reduced ice nucleation activity by Pseudomonas viridiflava strain W-1 as determined by freezing drops of the bacterial suspensions. Highest residual ice nucleation activity by dead cells was obtained by desiccation, although...
