4 Cool Fact Can Be Revealed from DNA
Friday, May 16, 2014
Since the discovery 60 years ago, deoxyribonucleic acid (DNA) has been used to uncover a lot of things, ranging from biological attachment between father and child or children with the mother to prove whether a person can be accused of committing a particular crime or not.
But probably not many know if DNA testing not only reveal things like that alone. Here are four cool facts can be revealed only on DNA testing as quoted by CNN.
1. Mapping the family tree
Who would have thought if you may still have a blood relationship with the leading celebrities? You can figure it out just by doing a DNA test.
No need to bother, sites like Ancestry.com are willing to compare your DNA with DNA recording various people around the world, hoping to hook you up with a family tree that you never knew before.
Not only that, Ancesty.com can also provide information about your genetic ethnicity.
"We can observe the massive amounts of DNA ... and compare it with other DNA samples from all over the world. Then to detect similarities that exist, we can trace back generations before you and connect you to your ancestors," writes the site The.
2. Solve an ancient mystery
Recently managed a team of archaeologists discovered the skull of one of the famous king of England that Richard III which was buried under a parking lot in Leicester. But investigators did not immediately believe it is a skull Richard III to DNA extracted from the bones of the king proved a match with Michael Ibsen, a direct descendant of the sister of Richard III.
This is not the first time the ancient relics can be identified thanks to DNA. The problem, though weather conditions were stored in a cool, dry and dark, DNA can last a long time, even up to thousands of years.
In 2009, DNA analysis of bone fragments prove that the two children of Czar Nicholas II was killed along with his entire family during the Russian Revolution, though so far there is speculation that the two managed to escape.
The scientists also succeeded in extracting DNA from ancient humans who have been extinct since the Neanderthals 30,000 years ago and the findings are expected to provide in-depth insight on the process of human evolution.
3. Predicting the future
By using a blood sample from the mother and saliva from the father, scientists can determine if their child is still in the womb will have a chromosome abnormality that can lead to genetic disorders such as Down Syndrome or not.
Later, the researchers also began to expand the functions of the prenatal genetic tests to identify potential developmental delays and intellectual disabilities such as autism in children.
Even genetic tests can also reveal certain health risk factors that you may have inherited from your parents, for example, the risk of breast cancer or colon cancer.
Although the determination of risk factors through genetic testing is no guarantee you are exposed to the disease, at least you know if you are likely to develop a certain disease. On the other hand, knowing the high risk such as this can encourage you to take some preventive measures.
4. Help you lose weight
According to a study, a persons ability to lose weight or otherwise established or determined by the genes you have.
The researchers themselves have identified several gene variants that may affect a persons potential for obesity, even down to their children. Studies in mice also ensure that 80 percent of body fat is regulated by genes.
"Although have found a genetic component that makes us prone to obesity, in fact, our understanding of this fact is very limited," said a diet and fitness expert Dr. Melina Jampolis.
From there, the researchers tried to figure out how to combine genetic factors, setting nutrition (diet) and exercise to help people lose weight and keep it off.

Asthma can be cured by itself when an adult child
Asthma can be cured by itself when an adult child - Asthma sufferers would be so excruciating, especially if the affected are children. However, a recent study indicates that asthma can be cured by itself when the children get older. Unfortunately, the possibility of recovering this only occurs in one in five children affected by asthma.
Even so, it would not seem to apply to girls who had asthma as allergic to furry animals like dogs and cats. Research has shown that girls with the allergy to heal on its own as an adult is quite small.
These results were found after Swedish researchers followed 200 children with asthma. When 19-year-old, 21 percent of children has decreased asthma symptoms. They no longer frequent shortness of breath and did not need the inhaler device. Decrease in these symptoms is more common in boys.
"The sensitivity of the furry animals and asthma are more acute at the age of seven to eight years did not decline as adults," said study author Dr. Martin Anderson from the Obstructive Lung Disease in Northern Sweden, as reported by U.S. News.
Many children who have asthma as a child had fallen when grown. But doctors rarely consider it a cure for fear of asthma will appear again when the children met with asthma triggers. Researchers found that the reduction rate can range between 16-60 percent in adolescents.
This study provides hope for parents to see their children recover from asthma. However, this study also did not provide a guarantee. Unfortunately, this study did not clarify whether the treatment of asthma like allergy shots can affect the possibility of recovery from asthma in the future.

Why pregnant women can develop diabetes
Thursday, May 15, 2014
Why pregnant women can develop diabetes? - About 18 percent of pregnant women who were suffering from diabetes. Diabetes is precisely called gestational diabetes. The cause is due to changes in her bodys response to insulin during pregnancy.
So what are the risk factors and prevention can be done by pregnant women? Listen more, as reported by U.S. News following.
Risk factors
Diagnosis
If you are at high risk of gestational diabetes, should check blood glucose levels on a regular basis since the beginning of pregnancy. If you tested positive for gestational diabetes, your doctor will usually recommend treatment and recovery program in order to maintain health of the mother and fetus.
Impact
Gestational diabetes can increase the risk of giving birth to a baby weighing more than 4.5 kg so it would take delivery by Caesarean section. Pregnant women with gestational diabetes are also at risk of hypertension or pre-eclampsia.
Treatment
Gestational diabetic pregnant women should follow a healthy diet in order to control blood sugar levels. If diet can not handle it, pregnant women should undergo insulin therapy to prevent complications of other diseases that attack the health of both mother and fetus.
Parties to the American Diabetes Association recommends that pregnant women have gestational diabetes to conduct further investigation in six to 12 months after delivery.

Risk factors
- Had a history of gestational diabetes in a previous pregnancy.
- Overweight or obese.
- Over the age of 25 years.
- Have a family history of diabetes.
- Previously delivered a baby who weighed more than 4.5 kg.
- The content of glucose in urine is quite high.
- Bloody Afro-American, Hispanic, American, or Asian.
- Suffering from symptoms of pre-diabetes or impaired glucose tolerance.
