      A New Chemical Discovery May Eliminate Cavities

      July 11, 2012 /

      A new compound might be able to prevent cavities.

      Keep 32 was discovered by researchers Jose Cordova from Yale University and Erich Astudillo from the Universidad de Santiago in Chile, who discovered the chemical and said it is able to eliminate the cavity-producing bacteria Streptococcus mutans which causes decay.

      Although not everyone in the dental community is optimistic, the uses of Keep 32 as additives to mouthwash, toothpaste, chewing gum and candies, may work to reduce bacteria enough to make the battle with tooth decay a little easier.

      To effectively prevent tooth decay, Curatola recommended avoiding harsh detergent toothpastes and alcohol-based mouthwashes, which disturb the balance of the oral biofilm, eating a healthy diet high in ‘alkalizing’ green foods and low in acidic foods such as refined carbohydrates, sugar and soda, and eating anti-inflammatory foods because inflammation causes profound effects on all organ systems in the body and can relate to gum disease and tooth decay.

      Summer Heat Can Be Deadly But Why?

      July 5, 2012 /

      Record heat has claimed 23 lives and the weather shows no signs of letting up.

      But what is it that causes people to succumb to high temperatures?

      The ability to sweat is what keeps the body cool.
      Once high humidity becomes part of the equation, sweating is no longer as effective.

      Extreme temperatures make it difficult for a heat-stressed individual to be aware of the danger since the brain and central nervous system are particularly sensitive to high internal temperatures.

      Hot weather alone is not dangerous, said Chris Minson, an environmental physiologist at the University of Oregon, Eugene. Instead, it’s a combination of hot temperatures, high humidity, and often preexisting health conditions that can push a person’s core body temperature to reach the danger zone of 104 F. At that point, the nervous system goes haywire, the heart experiences excessive stress, and organ systems begin to fail.

      Over The Counter HIV Test Approved By The FDA

      July 3, 2012 /

      The FDA has approved a rapid at home HIV test.

      OraSure Technologies Inc. of Bethlehem PA. has produced OraQuick for over-the-counter sales.

      The hope is that the at-home test will reach the 20 percent of HIV infected people who do not know that they are infected.

      Taking the test will not eliminate the need to follow up with further testing.

      The test has the potential to identify large numbers of previously undiagnosed HIV infections. An estimated 1.2 million people in the U.S. are living with HIV infection. About one of every five don’t know they’re infected. About 50,000 new HIV infections are diagnosed every year.
      percent accurate in correctly identifying positive results, a measure known as sensitivity, clinical trials showed. That means that one false negative test result could be expected out of every 12 tests.
      It was also about 99.98 percent accurate at correctly identifying negative results, a measure known as specificity. That means one false positive would be expected out of every 5,000 test results in uninfected individuals.

      OraSure expects the at-home HIV test to be available starting in October at more than 30,000 retail outlets across the U.S. and online.
