Health News: Medical Breakthroughs

If you are reading health news on a regular basis, you would understand how diligent these people are. Here are some of the breakthroughs in medical and health science that have significant impact on our lives.

Over the years, medical scientists have
worked so hard to shed light to the most puzzling areas of health and
medicine. These people spend most of their time doing research for
the benefit of the humanity. If you are reading health news on a
regular basis, you would understand how diligent these people are.
Here are some of the breakthroughs in medical and health science that
have significant impact on our lives.

Disarming HIV

One of the most talked about
breakthroughs today is the discovery of the Achilles Heel of the HIV.
American and European scientists have found a way to disarm the virus
and keep it from wreaking havoc in the immune system. The method
involves extracting the cholesterol from the virus, a method that
extinguishes its defenses. Without this cholesterol, the virus loses
its weaponry and becomes open for the human immune system to destroy.
HIV is known for disabling the adaptive response of the immune
system. Since the discovery of the human immunodeficiency virus,
scientists have been finding a means to fight it. None so far has
been so successful. Vaccines in the past were useless. But things
might change now that a new way to weaken the virus has been
discovered.

Aspirin for Cancer Prevention

It has been found out that taking small
amounts of aspirin on a daily basis can curb risk of stroke and heart
disease. We already know that. But recent studies indicate it can
also decrease risk of cancer. Studies done in United Kingdom have
been conducted to monitor subjects taking about 75-300mg of aspirin a
day. After three years, those taking aspirin had cancer risk reduced
by approximately 25%. Then after 5 years, risk of cancer was reduced
to 37%.

Studies indicate that daily intake of
aspirin cuts down cancer risk by preventing metastasis. Nonetheless,
there is another problem with aspirin intake. Doctors warn that
regular intake of aspirin may cause stomach bleeding. Moreover,
people who take aspirin daily are, ironically, at risk of hemorrhagic
strokes.

Placebos As Drugs

Placebos are “empty” agents used in
research to determine the true effects of drugs. This time they are
used as treatment agents on their own. The power of placebos comes
from suggestion—not from the placebos themselves. For instance,
studies show that when people are told they are getting good
exercise, they tend to lose more weight than those who are not told
the same thing. There are already many studies that test the ability
of placebo to treat disorders. Placebos do not contain active
ingredients to target the illness. They work by changing the person’s
reaction to their illness.

Exercise to Defy Aging

People already know the benefits of
exercise. Health news articles have discussed too much about
exercise. Anyone can now say exercise relieves stress, improves
cardiovascular health, enhances immunity, and so on. What we might
have missed to note is that exercise promises to reverse aging. This
assumption was made by scientists who studies laboratory mice
subjected to exercise program. These mice had better muscles, hearts,
kidneys, and brains than those that did not go through exercise
program. Their hair was also shinier and thicker.
