Please help to my son

My name is Nazira, I am from Azerbaijan, and I am asking for everyone's aid to help to my son Asim. This is our story:

My son Asim is a sweet, caring, generous and full of life man. He always was a determined hard worker, and thanks to his skills he was invited to work in an oil company in Kazakhstan. On 02/02/2010 while Asim was coming back from work, he was attacked by unknown people, robbed and left on street to die in the cold winter night. He was found unconscious and rushed to a hospital. Due to severe head trauma and injuries, Asim fell into a coma. After waking up, he lost his vision in both eyes, he has speech disorders and physical disabilities.

Since that time he has been receiving treatment in various hospitals, which, although leading to some improvements, did not help him restore his sight or physical activity.

We have a chance to restore Asim's vision loss using stem cell therapy. But this treatment is extremely expensive and requires overseas travelling.

I lost my husband to brain tumor in 2004, my eldest son died in a plane crash in 2005 in Azerbaijan. Please help to my son. There is nothing worse for a parent than seeing your child in a physical and mental pain, and not being able to help him.
