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.)

That is to say if a protostar has at least 0.08 times the mass of our sun and has a temperature of at least 107 K, hydrogen fusion can begin in it and it will become a star. Hydrogen fusion is the longest stage in an active stars life and so is considered the main sequence of a star.1]. The other process through which hydrogen can fuse into helium in a star is called the carbon cycle. This process will occur if the star has carbon present with in it and if the stars temperature is 2x107 K or greater. Equations (6)-(11) outline the series of reactions that occur in the carbon cycle.
