Painless adhesive promises to replace injection needles and vaccines
For those who suffer from the fear of needles, being vaccinated or taking an injection is almost a nightmare. However, each day we approach a scenario where the needles no longer have. A creation of American researchers at the National Institute of Health and together with the Georgia Institute of Technology promises to make a lot of people celebrate: a simple adhesive, easy to use and as efficient as a needle (but without the pain and discomfort) .
The novelty acts by means of micro needles that insert the drug into the bloodstream. The patch tested positive for 100 patients aged 18-49 who had not been immunized against influenza between 2014 and 2015 in a vaccination campaign in the United States.
When placed on the skin, the patch spreads the vaccine for whole body and the results show that the effectiveness was maintained after six months of application. In addition to being painless and very practical, the adhesive can also be applied by the patient himself. The novelty still has to go through new tests, including a larger sample of participants and testing it against other diseases.
? In the case of the sticker, you can buy it at a pharmacy and take it home. After putting on your skin for a few minutes and removing it, the discard can be done safely, since the microneedles dissolve in prolonged contact with the skin. There is also the advantage that adhesives can be stored outside the refrigerator, which makes them more accessible, "says Mark Prausnitz, one of the authors of the study.
Caries, plaque, gingivitis and blemishes are just the tip of the iceberg of inadequate oral hygiene. Lack of brushing and poorly cleaned can favor everything from the most common oral infections to cardiovascular diseases - because bacteria accumulated in the teeth can enter the bloodstream and reach the heart, hampering its functioning and increasing the risk of problems such as heart attack.
A survey by the American Association of Orthodontics (AAO) shows that 66% of the population has a problem of poor tooth positioning. However, archaeological studies indicate that our ancestors rarely had this problem. Basically, orthodontics uses two forces to move teeth: pressure and traction. Anything that exerts one of these forces on the teeth is able to move it.
