Scientists create injection capable of applying all childhood vaccines at a time
Ever wondered if instead of having to take your child to get vaccinated several times, there was an injection with all the vaccines he needs to take as a child?
A group of scientists developed a new approach to delivering many doses of immunizing substances in a single dose.
The technology would work from microscopic capsules that would be injected from one which is unique in the child and would release specific antibodies from time to time.
According to the scientists this type of discovery is important because one of the biggest limitations with regard to immunization is the need to have to return several times to obtain the immunity against the pathogen. p>
To test the effectiveness of the vaccine, the scientists injected the microparticles into rats using a fluorescent substance. Then, from an imaging technique, the substance was monitored to be released into the body for nine days. 20 days or 41 days.
The results revealed that the microparticles elicited a response greater than two regular injections of the same dose of the protein spaced at four weeks apart. the slow or timed release of a dose, and thus reduce the amount of vaccines without compromising immunization would be welcomed by health professionals and parents. P> However, scientists still face challenges ahead. This is because the chance of taking different vaccines in a single dose would eliminate the possibility of modifying vaccine antigens. In addition, scientists are also cautious about the release of vaccines into the body. For it could be dangerous if the antidote against malaria were released at the same time that a child has an acute illness.
Cancer is one of the most feared diseases currently due to complexity. Treatment against tumors, even though it is usually effective, is accompanied by horrible side effects. In addition, in the process of chemotherapy and radiotherapy, when tumor cells are destroyed, many healthy cells are also harmed.
Thyroxine (T4) is a hormone that, along with triiodothyronine (T3), controls how every cell in the body spends energy. This process is called metabolism. When the thyroid produces too much T3 and T4, our metabolism "accelerates". When the thyroid produces little T3 and T4, our metabolism becomes "slower.
