5 Uses DNA Tests

Deoxyribo Nucleic Acid or DNA is a nucleic acid that stores all the information about genetics. DNA that determine your hair type, skin color and specific qualities of the man. Should do a DNA test?

With DNA testing, so if someone knows that he is susceptible to a particular disease, theoretically it will conduct prevention efforts, such as the control diet or routine checks.

There are 5 DNA tests that actually needs to be done as reported Menshealth:





1. DNA tests to determine the risk of prostate cancer.

DNA testing is done by analyzing five genetic variants in saliva. A study in the New England Journal of Medicine found that men with four of the five variants have an increased risk of prostate cancer is 450 percent higher than the other guy.

The company has claimed assay 99.9 percent accuracy. But its weakness, this test is no longer available after October 2008. In addition, according to Muin Khoury, MD, Ph.D., director of the Centers for Disease Control and Prevention (CDC), U.S., a family history of prostate cancer is enough to predict risk.

2. DNA tests to determine lineage (father or mother)

This test promises to provide definitive results on the identity of the child's parent (either father or mother) in 3 to 5 days.

3. DNA tests to determine Alzheimer's disease

These tests look for variants of the gene known as APOE and associated with Alzheimer's disease. But its weakness, not all Alzheimer patients carrying this gene variant. In addition, the risk of Alzheimer's can also be seen from the factor of age, gender, ethnicity and family history.

4. DNA test to find out various degenerative diseases

This test can determine susceptibility promise of 18 illnesses, from heart attacks halted with type 2 diabetes (diabetes due to lifestyle) and colon cancer. But its weakness, for this test the price is very expensive. For the initial test you have to spend money of $ 2,500 or approximately USD 22.5 million.

5. DNA tests to detect baldness

This test promises to be looking for genetic variants associated with 95 percent of male baldness, especially at the age of 40 years. The presence of the gene variant showed an increased risk, but does not always guarantee the baldness.

This is the Activities Beyond Awareness, When Your Sleeping

Among the different types of sleep disorders, parasomnias among the most worrisome. This disorder can make a person do a variety of activities during sleep unconsciously.

If the impact of sleep disorders in general, only depression and fatigue, the impact could be more severe parasomnias. For example, when someone is sleepwalking, he could have an accident. Or if you smoke when asleep, the bed can fire.

Quoted from ABC News, an array of activities such alarming of them are as follows.

1. Run
Sleepwalking or walking during sleep can be caused by a variety of factors, including drugs, stress and lack of sleep. Most often occurs at the age of 8-12 years and usually dwindle while growing up.

When he awoke, a man walking in his sleep can not remember what he did. Some criminals also use this excuse as a justification to avoid heavy penalties.

2. Talk
Almost everyone would ever come across friends or relatives were ngelindur or talking during sleep. Besides triggered by drugs, this behavior can also be caused by stress and other mental disorders.

Ngelindur occurs when a person is in the phase of sleep called Rapid Eye Movement (REM), which can develop into REM Behavior Disorder or REM behavior disorder. At disorders are more related to the decline in brain function, the words spoken when ngelindur inclined rough example yelling, screaming or cursing.

3. Eating, drinking and smoking
Some people wake up with a sense of shock due to have her bed filled with cigarette butts and leftover food crumbs. However, the person does not remember how to get there food in that place.

There also are increasingly surprised to find an empty refrigerator in the morning and thought there was a burglar broke into his house hungry. And without realizing it, he walked in his sleep and then take the food and eat it in bed.

The reason there is a variety, such as the use of antidepressant medications. Stress and health problems such as piles or haemorrhoids is rumored to also increase the risk of developing this kind of behavior.

4. Sending SMS
Teens who already feel addicted to technology can not be separated from the phone, even while sleeping. The effects can be dangerous, because some people can send SMS or email even when asleep and when he woke he could not remember what he had done.

Unlike ngelindur, SMS texting during sleep or sleep more often occurs in the early phase when a person has not really asleep. What often happens is that there is an incoming SMS, then automatically typed his reply but everything going on outside of awareness.

5. Having sex
Journal of Sleep Research noted about 8 percent of people with sleep disorders had sex involuntarily during sleep. This figure is obtained based on the recognition of their partner, because pelakuknya can not remember what he did all night.

Seksomnia or having sex while asleep, including parasomnias are classified into subcategories arrousals confusion. This disorder occurs when a person loses status clear boundary between waking and sleeping.

New Invention! For Smart Brain electrocuted

Oxford, dyscalculia is a learning disorder characterized by difficulty calculating numbers. The flow of electricity in certain parts of the brain was able to overcome this disorder and even the effect can last up to 6 months.

Of course the power flow to the brain is not as easy as turning on the lights. There are certain techniques which if not done properly it causes the opposite effect that the more difficult math problems.

In an experiment, scientists from Oxford University managed to find the right technique to overcome dyscalculia with electricity. This experiment involved 15 students ranging in age from 20 to 21 years.

When an electric current by 1 milliamps (mA) flow in the brain in the parietal lobe that governs numerical and mathematical skills, the volunteers felt the effects are quite significant. However, the effect is a variation depending on the direction of electricity.

If the flow of the right parietal lobe to the left, numeracy volunteers increased by 2-fold. Conversely when the flow from left to right, the ability to drop dramatically to something comparable to children aged 6 years.

Because the techniques are far more complicated, one of the scientists is Dr. Cohen Kadosh reminded that this technique does not try yourself at home. However the technique is still in the testing phase so there is still more research is needed before widespread use.

"This is not going to change someone to be as smart as Einstein, but Juka lucky someday be useful for those who have specific learning difficulties such as dyscalculia," said Dr. Kadosh as quoted from the Telegraph
