A general technological advance is the magnetic resonance imaging (MRI) system. It uses a large magnet and the hydrogen protons in the human body to create images through the way tissues in the body react with these magnetized protons. Using this system, doctors have managed to diagnose various illnesses without needing surgeries of any kind, including vascular, digestive and respiratory problems. Technology being able to help people with many different kinds of problems is definitely something to appreciate.
Diet is one of the areas in which society has definitely changed. Many people don’t have the time (or the aptitude) to cook food anymore, leading to more store-bought meals and food. Add in the nights out at restaurants and the snack foods between meals and you’ve got the perfect formula for heart disease. It’s known that restaurants want their food to taste the best and please their customers, but it all comes at the cost of salt and fats. Fast food is even worse when it comes to containing fats. Snack can be the worst, being eaten on a whim and full of saturated and trans-fats that you wouldn’t otherwise have taken in. All of these fats will end up leading to clogged arteries, which is a major health concern.
Clogged arteries can be factors leading to many different types of cardiovascular disease, including heart attacks, strokes and high-blood pressure. Fat deposits gather at one point in the artery, and can reduce their diameter significantly, leading to those problems. Blood clots are also a problem, often being formed at the clogged points and reducing the amount of blood and oxygen movement even more. Sometimes, when arteries are completely clogged, a heart bypass surgery is necessary. This is a type of open heart surgery where blood vessels are taken from other areas of the body (usually the patient’s leg) and the clogged portion is replaced. Although generally successful, it can be sometimes very risky and dangerous for the patient.
There are two new technological advances that have created potentially revolutionary methods of dealing with clogged arteries. Researchers in Israel have developed protein-based injections that can promote the regrowth of blood vessels. This can lead to the elimination of bypass surgery all together. “The growth of new blood vessels happens within a few weeks, showing improved blood circulation,” says Dr. Britta Hardy (ScienceDaily). The new blood vessels are integrated into the circulatory system and have yielded promising results in mice. The second method comes from Sweden, where Helen Fink has used bacteria to synthesize new blood vessels. Acetobacter xylinym is a bacterium that can produce cellulose-based blood vessels compatible with the natural human body’s circulatory system. Fink and her research team have harnessed a natural way of creating completely new blood vessels that are less susceptible to further clotting. Both these advances have lead to new ways of looking at a surgery that still has many risks.
Another advance dealing with blood vessels is the treatment of multiple sclerosis (MS). A professor of medicine at the University of Ferrerra, Paolo Zamboni’s wife suffered from MS, and he was determined to find a cure. After much research, he discovered a startling trend. 90% of people with MS had blood vessels that drained blood from the brain were reduced in diameter or blocked. These damaged blood vessels lead to iron remaining in the un-drained blood and damaging the barrier between the brain and blood. Immune cells crossing the barrier destroyed the myelin, or protective layer, of the nerve cells. He discovered that by unclogging the veins and having blood drain normally, many of the MS symptoms disappeared. This research is a large step forwards into discovering a possible cure for this vascular disease.
There have been many biotechnological advances involving the systems of the human body over the years that have definitely had a positive impact on the way medical treatment is received by people everywhere. Here in North America, most of these advances are a way of fixing problems that were caused by the way we live. Bypass surgery would be less wide-spread if our diet wasn’t full of bad fats and sugars. As it was asked earlier, is this a good use of our research?
The question of fixing the problem at the root as opposed to fixing the consequence once it arises is always a difficult question. Should researchers around the world be discovering ways to reduce the chances of cardiovascular disease before it becomes too big a problem? Should they be figuring out ways to reduce the amount of pollutants that are creating respiratory illness worldwide?
The truth is, there is only so much that they can do. They can give you all the materials and resources to help reduce the chance of damaging the major systems, but if people don’t want to change their lifestyle for the better, there is nothing else that can be done. Sure, biotechnology has taken us further in providing easy ways of becoming healthier, such as methods of getting fresh vegetables all year. Most of the technological advances involve fixing the consequences of our actions, instead of the problem. Maybe it’s because we can’t see past the issues in our sights, or maybe it’s because we don’t acknowledge the root as a problem. Either way, something is going to have to change.
Although biotechnology has definitely improved over the years, offering advances that cater to the needs of people facing illness, it seems that something still must be changed to completely fix the problem. We need to become more focussed on living healthy lives, whether that is through proper diet or active lifestyles. We can’t depend on technology to fix all of our problems, especially since it was one of the causes of our current situation. Even as technology continues to improve the field of medicine, it is still up to us, as the individuals, to take initiative and improve our quality of life by being the embodiment of healthy living.
