Human Stem Cells Return Motor Function to Paralyzed Rats
Researchers from the University of California, San Diego report that experimental rats recovered from blood flow related paralysis after receiving grafts of human spinal stem cells.
When damage occurs due to loss of blood flow to the spine's neural cells, applying human neural stem cells directly to the spinal cord achieves recovery of motor function. In this specific type of paralysis, known as spinal cord ischemia, there is no mechanical damage to the spinal cord. The brain motor centers remain partially connected to the spinal cord but the loss of inhibitory neurons leads to the degeneration of muscle control in lower limbs.

The cause of cancer lies deep within the building blocks of a person's cells (genes and DNA). If these blocks become disorganized, cancer may develop.

Fat Study
An important medical study shows what you see all around you. It might sound plain and simple, but the study looked at obesity trends and found that most of us are getting- plain and simple- fat.
This is one of those studies that makes people wonder whether time and money haven’t been invested in deducing the obvious.
What makes the study important is that the research comes out of a comprehensive survey of obesity trends in a community over decades. The message is very clear- most of us are headed down a fattening road of destruction to our health.

What is Cancer and How it is Caused
Cancer is a term used to describe a group of illnesses all having certain common characteristics. There are over 200 different types of cancer and all have a specific name, treatment and a chance of being cured. The human body is made of organs, such as the brain, liver and heart. And each of these organs is made up tissues, such as fat, blood vessels and muscles.

REHNQUIST SURGERY
Chief justice William Rehnquist’s diagnosis of thyroid cancer is a concerning one.
His age, and the fact he needed to have a breathing pipe put in has experts worried about his overall prognosis.
