Terapia gênica: Os genes em busca da cura
Resumo:
The possibility of modifying human genes has been the main objective of medicine since DNA was discovered. Gene therapy can be defined as the improvement of human genes, whether to correct an anomaly, or to modify the cell or tissue, for therapeutic purposes. Gene therapy is nothing more than a medical procedure that modifies cells, with the purpose of treating or curing the gene that causes a certain disease. There are already medicines released under the regulatory category of advanced therapies, however, many other studies are still being carried out, in search of the development of new molecules. One of the most important points of gene therapy is the development of safe, effective and efficient methods for transferring genes into human cells. With the development of these new drugs, we have a very positive outlook regarding the use of these drugs in the general population, in addition to being more effective for mass diseases, such as cancer, for example.
Keywords: gene therapy, vectors, genetic transfer.

The growing interest in less invasive alternative therapies has reignited research on the efficacy of aromatherapy, especially in contrast to the side effects of conventional medications. Although their application in pharmaceuticals declined throughout the 20th century, recent studies confirm their relevance. Aromatherapy can not only reduce self-medication but also serve as a complementary option to traditional medicine, highlighting the importance of the quality and provenance of the oils used. Conclusions:Aromatherapy is an effective alternative in treating respiratory diseases, utilizing essential oils such as eucalyptus and peppermint, which possess antiseptic and anti-inflammatory properties. In addition to alleviating symptoms, it may reduce self-medication and the inappropriate use of antibiotics. The quality of essential oils is crucial, and ongoing research is necessary to consolidate aromatherapy as a recognized practice, contributing to respiratory health and overall well-being.

Resumo:
This study aimed to identify good practices for handling oral cytotoxic antineoplastic drugs. This is a narrative, qualitative, exploratory and explanatory bibliographic review work. The data were collected and organized in a synthesized way through the analysis of all articles used to support this scientific work, thus generating two categories of analysis that will be exposed below: care in the use of oral cytotoxic antineoplastic drugs and good practices by the team in handling these. However, it was possible to observe that it is of fundamental importance that professionals directly involved in the handling of oral antineoplastics are prepared, theoretically based to deal with the appropriate guidelines to be offered to the patient and family, in situations of handling, administration and correct disposal of drugs. cytotoxic.
