What Are The Potential Benefits In Adult Stem Cell Use?

http://stemcells.nih.gov/info/health.asp

According to the National Institutes of Health: Adult stem cells, such as blood-forming stem cells in bone marrow (called hematopoietic stem cells, or HSCs), are currently the only type of stem cell commonly used to treat human diseases. Doctors have been transferring HSCs in bone marrow transplants for over 40 years. More advanced techniques of collecting, or "harvesting," HSCs are now used in order to treat leukemia, lymphoma and several inherited blood disorders.

The clinical potential of adult stem cells has also been demonstrated in the treatment of other human diseases that include diabetes and advanced kidney cancer. However, these newer uses have involved studies with a very limited number of patients.

Another potential application of stem cells is making cells and tissues for medical therapies. Today, donated organs and tissues are often used to replace those that are diseased or destroyed. Unfortunately, the number of people needing a transplant far exceeds the number of organs available for transplantation. Pluripotent stem cells offer the possibility of a renewable source of replacement cells and tissues to treat a myriad of diseases, conditions, and disabilities including Parkinson's and Alzheimer's diseases, spinal cord injury, stroke, burns, heart disease, diabetes, osteoarthritis and rheumatoid arthritis.

Stem Cell Enhancement: Beyond The Doctors - Hot News!

The first human embryonic stem cells were grown in vitro, in a petri dish, in the mid 1990s. Rapidly, scientists were successful at growing them for many generations and to trigger their differentiation into virtually any kind of cells, i.e. brain cells, heart cells, liver cells, bone cells, pancreatic cells, etc.

When scientists tried growing adult stem cells, the endeavor was met with less success, as adult stem cells were difficult to grow in vitro for more than a few generations.

This led to the idea that embryonic stem cells have more potential than adult stem cells. And, there are ethical concerns linked to the use of embryonic stem cells. But recent developments over the past 2-3 years have established that adult stem cells have capabilities comparable to embryonic stem cells in the human body, not in the test tube.

Many studies have indicated that simply releasing stem cells from the bone marrow can help support the body's natural process for renewal of tissues and organs.

Real News! Drunk NC State Student Kills Cyclist

Raleigh isn’t the most bike friendly place but that has never stopped the area’s forward thinkers from using this alternative transit. Any day of the week you will see dozens of cyclists around town sliding through traffic. Thats why its so disturbing to hear news like what the N&O reported yesterday. NC State student Brian Reid, just 21, hit and killed 60 year old Nancy Leidy who was cycling. Leidy an unpaid entomology professor at N.C. State University, was a recreational cyclist who had just done the same ride this past Sunday.

Reid had a blood alcohol level of .12 and it was 11 am. There is no ‘safe time’ as a cyclist. You always have to be vigilant and wear safety equipment, even then you probably aren’t ‘safe.‘ New Raleigh is using this event to encourage all of its young readers to please wear your helmets. So many of our friends ride the streets with no lights or helmets in the dark of night and we think it would be a whole lot cooler if you did, man. Be safe be smart and take Dr. Leidy’s fate to heart- you aren’t invincible. Read more here.

Weird and Funny Law: Poland 'can jail drunk cyclists'

(Source: BBC News) Poland's Constitutional Court upheld a ruling this week that drunken cyclists should be treated like drunken motorists and face prison if caught.

Two thousand Poles are currently in prison for riding a bicycle whilst under the influence of alcohol.

The ruling has sparked a lively debate about whether cyclists should face such strict punishment.

The Constitutional Court ruled that drunken cyclists should be tried as criminals just as drink drivers are.

'Absurd, draconian'

Under a law passed in 2000, anyone riding a bike under the influence of alcohol faces a fine or up to two years in prison, depending on the level of their intoxication.

Many courts here apply the stricter penalty and the average sentence is 11.5 months imprisonment.

Such a state of affairs has been criticised by both the prison service and some judges.

Jaroslaw Sielecki, a 37-year-old judge from western Poland, called it absurd and draconian, adding that it can drag whole families into poverty.

He argued that intoxicated cyclists should be treated like drunken pedestrians, who face a fine rather than jail, as both use their own muscles to achieve motion.

The Constitutional Court, however, ruled that cyclists use public roads and are considerably more dangerous because of the speed they can travel.
