Dew 4:a single pill!

A new pill to treat HIV infection that combines four medicines and only has to be taken once a day was approved by the U.S. Food and Drug Administration.

Stribild
which will be marketed by maker Gilead Sciences, contains the HIV drugs elvitegravir, cobicistat, emtricitabine and tenofovir disoproxil fumarate. It will be prescribed to people who have never been treated for HIV infection, the agency said in a statement. Two of the drugs, elvitegravir and cobicistat, are new, the FDA noted. Elvitegravir interferes with one of the enzymes that HIV needs to multiply, while cobicistat inhibits an enzyme that metabolizes certain HIV drugs and so prolongs the effect of elvitegravir.

The combination of emtricitabine and tenofovir disoproxil fumarate is already marketed as Truvada, and they work in concert to block another enzyme that HIV needs to replicate.


dew 5: h2o2 potential!

Q:Is it safe to use hydrogen peroxidein cleaning dirty wounds?

A:Yes, but it is not advisable now a days because Peroxide is a solution made up of hydrogen and oxygen. It is a strong oxidizer and can be used as a cleaning agent and to prevent infections. When used topically, this antiseptic foams due to the enzyme catalase. As the catalase comes in contact with the skin it turns the hydrogen peroxide into water and oxygen gas.
 
 According to health experts at the Swedish Medical Center in Colorado, hydrogen peroxide contains too much oxygen for the blood leading to potential issues.  When your skin absorbs hydrogen peroxide, it can reduce the amount of fibroblasts, a particular cell that is imperative for cleaning and repairing damaged tissue
