[BioC] import miRNA data

[maryam [guest]]

hello
I have work with packages in bio-conductor that accomplish normalization miRNA data and determine the differentially expressed miRNA,which of them is better for this purpose?
another question is that when I get data from GEO database about MiRNA how can I import that data to packages?
 for example I work with" MmPalateMiRNA" and I get data "GPL10179" from GEO database how can I import this data and another data into this package?
please help me
thanks
