P504S can be used as a positive marker for PIN. It will be useful to. confirm the diagnosis of small focus of prostate carcinoma in needle biopsies. The combination of P504S + HMW CKs + p63 (PIN-4â¢ Cocktail) may be extremely. useful for diagnosing prostatic intraepithelial neoplasia, especially in difficult cases, and in cases with limited tissues.
C) Our Sun will probably undergo at least one nova when it becomes a white dwarf about 5 billion years from now. D) When a star system undergoes a nova, it brightens considerably, but not as much as a star system undergoing a supernova.)

In Astronomy, an eon refers to 1 billion (10^9) years. But it also refers to a very long, unspecified period of time, or specific geologic stages of the Earth. Since this question is posted in Astronomy, I will assume that the answer of eon = 10^9 years is the most appropriate, however it is not the most common. The term eon (or aeon) is frequently used as a term for a very long but un-specified time period, much the same way forever and ages are used.
