Chocolate is HEALTHY !!!!!

Chocolate is made from plants, which means it contains many of the health benefits of dark vegetables. These benefits are from flavonoids, which act as antioxidants. Antioxidants protect the body from aging caused by free radicals, which can cause damage that leads to heart disease. Dark chocolate contains a large number of antioxidants (nearly 8 times the number found in strawberries). Flavonoids also help relax blood pressure through the production of nitric oxide, and balance certain hormones in the body.

Heart Health Benefits of Dark Chocolate:

Dark chocolate is good for your heart. A small bar of it everyday can help keep your heart and cardiovascular system running well. Two heart health benefits of dark chocolate are:

• Lower Blood Pressure: Studies have shown that consuming a small bar of dark chocolate everyday can reduce blood pressure in individuals with high blood pressure.
• Lower Cholesterol: Dark chocolate has also been shown to reduce LDL cholesterol (the bad cholesterol) by up to 10 percent.

Other Benefits of Dark Chocolate:

Chocolate also holds benefits apart from protecting your heart:

• it tastes good
• it stimulates endorphin production, which gives a feeling of pleasure
• it contains serotonin, which acts as an anti-depressant
• it contains theobromine, caffeine and other substances which are stimulants

No more fillings? Gel regenerates teeth

Dentists could soon hang up their drills. A new peptide, embedded in a soft gel or a thin, flexible film and placed next to a cavity, encourages cells inside teeth to regenerate in about a month, according to a new study in the journal ACS Nano. This technology is the first of its kind.

The new gel or thin film could eliminate the need to fill painful cavities or drill deep into the root canal of an infected tooth.

"It's not like toothpaste," which prevent cavities, said Nadia Benkirane-Jessel, a scientist at the Institut National de la Sante et de la Recherche Medicale and a co-author of a recent paper. "Here we are really trying to control cavities (after they develop)."

Drilling teeth and filling them is safe and effective. Dentists fill millions of cavities each year across the United States. However, though dentists numb the tooth, many patients still rue the sound of that drill.
The new research could make a trip to the dentist's office more pleasant, said Berkirane-Jessel. Instead of a drill, a quick dab of gel or a thin film against an infected tooth could heal teeth from within.

Cavities are bacteria and pus-filled holes on or in teeth which can lead to discomfort, pain and even tooth loss. When people eat acidic foods, consume sugary snacks or simply don't maintain proper oral hygiene, bacteria begin to eat away at the protective enamel and other minerals inside teeth.
The causes of cavities are varied. But for most cavities, the treatment is the same: drilling into a tooth, removing the decay and filling in the hole to prevent further damage.

The gel or thin film contains a peptide known as MSH, or melanocyte-stimulating hormone. Previous experiments, reported in the Proceedings of the National Academy of Sciences, showed that MSH encourages bone regeneration.

Bone and teeth are fairly similar, so the French scientists reasoned that if the MSH were applied to teeth, it should help healing as well.

To test their theory, the French scientists applied either a film or gel, both of which contained MSH, to cavity-filled mice teeth. After about one month, the cavities had disappeared, said Benkirane-Jesse.

Benkirane-Jessel cautions that the MSH-containing films or gels only treat cavities; they don't prevent them. People will still need to brush, floss and use mouthwash to help prevent cavities from forming in the first place.

Treating cavities without drilling "would have its advantages," said Hom-Lay Wang, a dentist at the University of Michigan. Cavities and drilling can destroy the nerves and blood vessels inside a tooth, making it more brittle and likely to fracture. Regenerating a tooth could help avoid crowns after a cavity has been filled.
That said, regenerating a tooth from within would only be useful in a relatively small number of cases. Most cavities would still need to be drilled and filled.

In the meantime, patients can't slacken their oral hygiene either. Numerous clinical trials over several years will have to be completed before the MSH-containing gels or films are available to treat cavities in humans.

Blood test for cancer detection before it starts

In a major breakthrough, British researchers have developed a blood test that can detect cancer even before it develops and can be diagnosed with tests in use at present.

The new test, which replicates the cancer proteins that trigger the body’s response to the disease, has been developed by the University of Nottingham’s spin-out company Oncimmune Ltd. It will help detect cancer as much as five years earlier than testing methods like mammography and CT scans.
The blood test was developed from the early work of John Robertson, a world renowned breast cancer specialist and professor of surgery at Nottingham University. It is expected to change the current paradigm of diagnosis and treatment for most solid cancers such as lung, breast, ovarian, colon and prostate.
Initially, the blood test will be offered later this month via primary care physicians and pulmonologists in the United States for high risk asymptotic lung cancer patients as well as those who have indeterminate lung nodules. The test, which gives results within a week, will be introduced in the UK early next year.

“We believe this test, along with the others we will launch in the next few years, will lead to a better prognosis for a significant number of cancer sufferers,” according to Geoffrey Hamilton-Fairley, executive chairman of Oncimmune.

Initial research by Prof. Robertson was based on blood samples of breast cancer patients collected in Nottingham. His research revealed that cancer marker could be detected in some of the high-risk patients before they were subsequently diagnosed with cancer. Prof. Robertson showed that the test could have detected over half of the cancers up to four years before they were actually diagnosed.
