Precious metals are used not only as a store of wealth and jewels alone. Scientists recently made a vaccine that uses gold grains as basic materials. The gold vaccines have been tested to treat respiratory diseases in children.
The disease is caused by infection with respiratory syncytial virus (RSV), a major cause of respiratory infections in children. This
disease causes several hundred thousand deaths and about 65 million
infections per year, especially in children and the elderly.
The harmful effects of RSV caused by certain proteins, the F protein, which coats the surface of the virus. This
protein allows the virus to enter the cell and allowed him to live with
the body's cells, so the viruses are tough to eradicate.
Therefore, treatment of RSV are focused on the immune system can recognize protein F. But until now, scientists have difficulty creating a vaccine that targets the protein F. And if successful, the immune cells that have been given the F protein as the enemy can immediately provide protection response.
Researchers typically use a killed virus that is not active or as vaccines. But there are fears the virus dead or inactive can still be contagious. Therefore,
researchers at Vanderbilt University in the U.S. created the gold
particles are exactly the same size and shape of the virus.
The gold particles coated with the F protein of RSV. The researchers then tested their ability to provide the F protein to the immune cells. The
results, published in the journal Nanotechnology, the gold particles
not only failed to provide protein, but also non-toxic to humans.
"The
vaccine for RSV is a major cause of pneumonia in children is needed.
Research shows that we have developed a method for locating the F
protein in very small particles and give them to immune cells in the
physical form of the virus replicate.'s Just These particles are not infectious, "said researcher Professor James Crowe as reported by the Daily Mail.
Due to the flexibility of the gold grains, Professor Crowe believes that its use is not limited to RSV alone. He
believes that the same method can be used to create experimental
vaccine in almost all viruses and microbes are larger, such as bacteria
and fungi.
"Our
research shows that the vaccine can stimulate immune cells interact in
the human body when the lab. Next step is to test whether the vaccine
works in vivo (in a living organism)," Crowe said.

Nail biting, spitting exhaust gas and is often regarded as a bad and slovenly habits. But you know, this habit could actually be a good thing for your health? This is why, as quoted by the Daily Mail.
1. Nail BitingThese bad habits can be good for your health, according to Dr. Hilary Longhurst, an immunology specialist. He
explained the origin of the hand is not too dirty, the bacteria enter
the body through the mouth while biting nails can enhance the immune
system. Immune system has a memory and can be 'noted' how to fight bacteria if a time comes again.
When
bacteria enter the body for the second time, the immune system will
recall the memory and release weapons - called lymphocytes - who knows
how to fight it. So even though his role was small, mengigiti nails also contribute to endurance. Just like picking your nose. Just do not do this too often and habits in a very dirty state of hands, for example after handling raw meat, mud or dust.
2.Fart
Exhaust gas may be nasty, but it is important for the body remove the wind. "We're
wasting gas for a reason. Gases present in the intestine and must be
removed," says Dr Nick Read, digestive health specialists.
Most of the gas comes from the fermentation of protein and carbohydrates. Generally formed about six hours after eating. So if you eat at 7 pm, then at 2 am you'll usually feel a bit bloated stomach at the bottom. It signifies being the formation of flatulence.
Removing the gas will relieve pain and bloating, especially if you tend to be sensitive stomach. So as much as possible, you should not hold it when they want to waste gas. If there is in the middle of a meeting or a formal meeting, never hurts to ask permission to go out for a while. Because the gas hold out can trigger abdominal pain.
3. Make fingers creaking jointsWhen tired or sleepy, usually we will memeretakkan fingers making a sound like a broken bone. The sound it might make people who hear the pain, but actually there is no harmful effect by doing this habit. Makes the finger joints more flexible.
"There
is a myth that doing this could weaken the joints. But it turned out to
have no effect. A study conducted on a group of respondents over the
past five years did not show any symptoms of arthritis because of his
habit memeretakkan finger. Their finger joints as healthy people who do
not have the habit it, "explained Dr Chris Edwards, a consultant rheumatologist at Southampton General Hospital.
Cracking sound came from the fluid that lines the joints in each finger. When stretched, cracking voice will make the joints more flexible. That's why you feel more comfortable fingers and limp after doing it.
4. SpitThe habit of spitting is not good and can make people disgusted. If you do it in the street or a public bus. But spitting include healthy habits when performed during exercise or fitness, because it helps you breathe easier.
In normal activity, people breathe through the nose. The air in through the nose while being warm and moist, allowing the body to absorb more oxygen more efficiently. But
while physical activity, we tend to take a long, deep breath through
your mouth to inhale as much air as possible into the body.
"But
the air is not heated or moistened as when breathing through the nose.
When the air intake in the cold will make a dry throat and pushing the
cell to protect it by producing more saliva," says sports physician Dr
John Dickinson.
Too much saliva production will disrupt the rhythm of breathing so you need a lot of spit. This is mostly done by the runners to regulate his breathing steady.

Kirstie stories about negative behavior model was not intentionally starve first revealed. Formerly a British journalist, Imogen Edwards-Jones, who is known as the author of the book series Babylon also revealed something similar in his book 'Fashion Babylon'. In the book he wrote based on the narrative of three prominent figure in the fashion world that Imogen revealed that the mode often taking laxatives (constipation medication) and diet pills in order to stay thin body size.
