Preventative care encompasses a wide range of techniques to identify, educate, prevent and treat diseases in populations. There are three types of prevention that nurses take part in on a regular basis depending on their position in health care facilities or organizations: primary, secondary and tertiary.urses in preventative health care are tasked with improving the health of patients through evidence-based recommendations while encouraging individuals to receive preventative services such as screenings, counseling and precautionary medications.
Top2 have been used as targets for the development of anticancer drugs. These inhibitors include anthracyclines (doxorubcin, daunorubicin, epirubicin) and epipodophyllotoxins (etoposide), which are widely used in the clinic. These drugs poison Top2 by trapping the enzyme on its DNA cleavage sites, which results in irreversible double-strand breaks that are responsible for cell death.
An enzyme (protein) that's part of the human immunodeficiency virus reads the sequence of viral RNA nucleic acids (yellow in graphic) that have entered the host cell and transcribes the sequence into a complementary DNA sequence (shown in blue). That enzyme is called reverse transcriptase .Without reverse transcriptase, the viral genome couldn't become incorporated into the host cell, and couldn't reproduce. Reverse transcriptase sometimes makes mistakes reading the RNA sequence.The result is that not all viruses produced in a single infected cell are alike.ZT-like Drugs Inhibit Reverse Transcription. The first major class of drugs found useful in slowing HIV infections are collectively called reverse transcriptase inhibitors (shown in red). These include AZT, 3TC, d4T, ddc, and ddl that act by blocking the recoding of viral RNA into DNA.
