In the last few decades, amazing discoveries have been made in many different areas. In medical research alone, there have been discoveries that have changed our lives. Most of us cannot even remember how we got along with some of these discoveries. So, let’s have a look at some of the greatest medical discoveries in recent years.
The Circulatory System by Ibn al-Nafis. Ibn al-Nafis first described the circulatory system in 1242 and it was only brought into the light in 1628 by William Harvey. The discovery and further investigation of this system have made it possible for doctors to understand the body much better. It also helped to develop treatments and techniques involved with medicine that has made amazing differences in healthcare.
HIV discovered by Robert Gallo and Luc Montagnier. HIV was only discovered in the 1980s which makes it one of the more recent ones. It is an incurable disease, but its discovery has helped to create awareness about the dangers of unprotected sex. Its discovery has also led to treatments to help manage the disease.
X-Ray discovered by Conrad Rontgen. He made the discovery in 1895. The discovery of x-rays has made it possible to understand the human body even further and it has made identifying problems with bones so much easier.
Vitamins discovered by Frederick Hopkins. The discovery of vitamins in the 1900s has made it possible to understand nutrients and what the body needs much better. It also led to the prevention of illnesses and conditions that result from deficiencies of these vitamins.
DNA by Friedrich Miescher. The Swiss physician discovered DNA and originally called it ‘nuclein’. His discovery may be one of the most important of the medical discoveries so far. DNA has made it possible for us to understand diseases, genetics, illnesses, the nature of humanity, evolution, etc. It will no doubt continue to help researchers learn more about the human body, nature, and how illness is carried over in years to come.
These discoveries have forever changed the world and human life. Many of them will continue to be expanded and studied and will likely lead to even more great improvements and advances in the medical and other fields.
Stem cell research has helped to make several amazing medical discoveries. It offers a multitude of medical benefits and has the ability to save many lives. However, it is a very controversial topic when it comes to ethics. The very basic idea behind stem cell research involves creating and killing human life. In this lies the objections and issues that people have with stem cell research. Despite the advantages of the research, it holds more disadvantages according to some. Here are the disadvantages that they put forward:
It is still just theory – Until the techniques of stem cell research are successfully proven effective, it remains just research. The cures that it is said to bring out is still many years away from being realised. Many of the people against stem cell research would rather have researchers focus on more pressing and current problems than something that may work or may be effective in a few decades.
It is likened to murder – Once research on an embryonic stem cell has been completed or another one is needed, the used blastocyte must be destroyed. A blastocyte is basically a fertilised human egg. For this reason, opponents of stem cell research view it as murder.
The cells can be rejected – The cells used to help one person is derived from the cells of another person. There is no guarantee that the body of the receiver will accept the organ or cells. There are definite risks of cell or organ rejection of from the new host.
Unknown side effects – In order to see what the effect of a cure is, it needs to be used on people. Unfortunately, part of this process also involves learning about the negative and sometimes long-term side-effects. The question arises whether it is accepted to sacrifice one person’s life for the good of everyone else?
There is still a lot to be tested and learned when it comes to stem cell research. Chances are that there will always be those for and those against. We will have to see what the future holds to see how this one ends.
We are always warned against the side effects of medication and encouraged to use them as little as possible. However, recent studies have found that there are also positive side effects of regular prescription drugs that can improve your health and help fight disease. Have a look at the following medications that have surprise positive side effects.
Flu Shots – The flu shot can help reduce the risk of developing cardiovascular complications by almost 50%. It has to do with the shot blocking inflammatory responses that protect the arteries. When the arteries are safe from rupturing, it lowers the chance of a cardiac episode.
Levodopa and dopamine agonists – Levodopa and other dopamine agonists are prescribed to Parkinson’s patients. It was recently found that, despite the loss of motor skills, Parkinson’s patients seem to retain their creative abilities. It seems that these dopamine agonists have the ability to improve artistic capacities and creative faculties.
Cholesterol medication – Statins are often prescribed for people with high cholesterol These statins seem to help to reduce the risk of dying of cancer. Studies were done to see what the effect is in cancer patients. It seems that the statins reduce the rate at which cancer spreads which in turn reduces the risk of dying from cancer.
Aspirin – It is a well-known fact that many adults use aspirin daily to prevent heart attacks. This practice can also reduce the risk in men to develop colon or prostate cancer. Several studies have been done and they all found that a daily dose of aspirin lowers the risk of dying from prostate cancer or colon cancer.
Metformin for diabetes – It seems that improved insulin response in the body helps to prevent the development of breast cancer. In recent studies, it was found that women who took metformin for a period of three years, had drastically reduced their risk of developing breast cancer.
These findings are very interesting. We strongly advise against taking up any of these medications without consulting your physician or oncologist first.
