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.)

Proton-Proton Fusion. This is the nuclear fusion process which fuels the Sun and other stars which have core temperatures less than 15 million Kelvin. A reaction cycle yields about 25 MeV of energy.his is the nuclear fusion process which fuels the Sun and other stars which have core temperatures less than 15 million Kelvin.
