Transcription elongation by RNA polymerase II (RNAPII) is negatively regulated by the human factors DRB-sensitivity inducing factor (DSIF) and negative elongation factor (NELF). A 66-kilodalton subunit of NELF (NELF-A) shows limited sequence similarity to hepatitis delta antigen (HDAg), the viral protein required for replication of hepatitis delta virus(More)
We have previously reported that a small number of retinal ganglion cells (RGCs) of adult cats survive 2 months after transection of the optic nerve (ON) and that alpha cells have the greatest ability to survive among different types of RGCs (Watanabe et al., 1995). Here we report the time course of RGC survival within 15 days after ON transection using(More)
A segment of peripheral nerve was transplanted to the cut stump of the optic nerve to facilitate axonal regeneration of retinal ganglion cells (RGCs) in adult cats. The cats were reared under different light environment: 12 h light-12 h darkness, additional flash light under conventional light cycle, or 24 h darkness. After 60 days, the density and(More)
The protective effects of Rooibos tea (RT), Aspalathus linearis, against damage to the central nervous system (CNS) accompanying aging were examined by both the thiobarbituric acid reaction (TBA) and magnetic resonance imaging (MRI) methods in brains of chronically RT-treated rats. Ad libitum administration of RT was begun with 3-month-old Wistar female(More)
