Aamir,

Thank you for those excellent sources.  Only by analysing the available data can we understand what problems need to be worked on.

Srikanta

You welcome Srikanta. I'm struggling for collaboration with international researchers on topics of similar interest-as your profile shows your interest in cardiovascular-I would love to work with you if you consider me in future or I will be there to help also.
