Extravasation Management Vesicant chemotherapy agents can be divided into two categories: DNA binding and DNA non-binding (see Table 1). Vesicants that bind to nucleic acids in DNA (eg, anthracylines) bind to the DNA in the cells of healthy tissue when they extravasate from the vein and promptly cause cell death. DNA-doxorubicin complexes are released from dead cells in the tissue and are taken up by adjacent healthy cells by endocytosis.

Extravasation Management Extravasations of small amounts of non-DNA binding vesicants usually heal without a break in skin integrity ever occurring. In contrast, extravasation of a small amount of a DNA binding vesicant is likely to cause blistering and tissue breakdown.

EMSA gel shift assay Affymetrix EMSA (Electrophoretic Mobility Shift Assay) Kits are useful tools for identifying proteins that interact with DNA. This rapid technique is based on the different electrophoretic mobilities of free DNA and DNA/protein complexes in native (non-denaturing) polyacrylamide gels.

Antifungal Drugs: Major Types & Functions Fungal membranes have ergosterol instead. So, many antifungal drugs target ergosterol as a way to disrupt the fungal plasma membrane. These drugs make fungal membranes very permeable, meaning that cellular contents can leak out and molecules from the outside can get in. This causes the fungus to die, so these agents are usually fungicidal.

This assignment must be completed prior to attending this lab! Aldehydes, such as formaldehyde and glutaraldehyde, denature microbial proteins. Formalin (37% aqueous solution of formaldehyde gas) is extremely active and kills most forms of microbial life. It is used in embalming, preserving biological specimens, and in preparing vaccines.

- 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.

Transcription activator-like effector nuclease From Wikipedia, the free encyclopedia. Transcription activator-like effector nucleases (TALENs) are artificial restriction enzymes generated by fusing a TAL effector DNA-binding domain to a DNA cleavage domain. Restriction enzymes are enzymes that cut DNA strands at a specific sequence. Transcription activator-like effectors (TALEs) can be quickly engineered to bind practically any desired DNA sequence. By combining such an engineered TALE with a DNA cleavage domain (which cuts DNA strands), one can engineer restriction enzymes that are specific for any desired DNA sequence.

extravasation vs. infiltration Some chemos/other drugs are classed as vesicant/irritants. The potential to damage tissue varies with how they are mixed. For a long time taxol was not classed as vesicant, yet I have had some patients that had to be grafted from an extravasation of the drug. Taxol is now classed as vesicant/irritant.more pathophysiology on extravasation] an oversimplification of the chemistry of an extravasation divides [vesicant] drugs into two categories, those that bind to dna and those that do not. the drugs that do not bind to dna cause immediate damage but are quickly metabolized or inactivated.

Activator (genetics) A transcriptional activator is a protein (transcription factor) that increases gene transcription of a gene or set of genes. Most activators are DNA-binding proteins that bind to enhancers or promoter-proximal elements.he part of the activator that makes protein-protein interactions with the general transcription machinery is referred to as an activating region.. The part of the general transcription machinery that makes protein-protein interactions with the activator is referred to as an activation target..

Nettle agent Most nettle agents, such as the best known and studied nettle agent, phosgene oxime, are often grouped with the vesicant (blister agent) chemical agents. However, because nettle agents do not cause blisters, they are not true vesicants.
