Most patients are less than thrilled about colonoscopies, and it’s completely understandable.
The process often entails taking a sedative to help them relax while they lie on their sides as a doctor or nurse pushes a colonoscope up their rectum to check things out. It’s not too pleasant, to say the least, however it’s viewed as a necessary evil to help health professionals catch colorectal cancer.
But what if checking the colon for cancer was as easy as taking a spoon full of yogurt?
It may seem too simple to be true, but this cheap, non-invasive method created by MIT Professor Sangetta Bhaita may one day replace expensive, uncomfortable MRIs and colonoscopies.
So how can a yogurt detect cancer?
A synthetic molecule developed by Professor Bhaita is mixed into yogurt. Once the yogurt passes through the patient’s system, the patient would urinate on a urine strip, much like taking a pregnancy test.
Scientists have implanted a lab-grown vagina in humans, a medical first.
The patients, four teenaged girls, donated their own tissue to be used for the development of the vagina.
These girls suffer from Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome.
The vaginas were implanted in June 2005 and October 2008.
Their yearly follow-up visits concluded that the implants were a success with the lab-grown organs functioning normally, even during sex. Their tissue was acting just like the original tissue.
This study gives hope to patients who need vaginal reconstructive surgeries. It also helps establish the benefits of regenerative medicine strategies when used on human organs and tissues.
However, the operation is still waiting for FDA approval. Once it is rendered safe, it can even be used on men who looking for a s
Imagine if creating a solid, three dimensional prototype for anything you wanted was as simple as clicking “Print” from a computer. Well in this day and age, it is more or less that simple, thanks to a rapidly progressive technology called 3D Printing.
You can create a model of just about anything:
- A real prototype of an action figure you may have designed in Photoshop.
- A model of building’s blueprint made.
- A body part that could change a patient’s life.
How 3D Printing Is Changing Lives
Take for instance the case of Hu Wei, a 46-year old from Beijing, China.
He was working on a construction project when he fell three stories into a pile of wood. A beam struck him in the head, leaving him with a large portion of his skull caved
