How does Thermally Sensitive Liposomes Work?
Virty [35]

Answer:

Thermosensitive liposomes (TSL) are promising tools used to deliver drugs to targeted region when local hyperthermia is applied (∼40–42°C) which triggers the membrane phase transformation from a solid gel-like state to a highly permeable liquid state. Selective lipid components have been used to in TSL formulations to increase plasma stability before hyperthermia and speed drug release rate after. Two generations of TSL technology have been developed. The traditional thermal sensitive liposomes (TTSL) have utilized DPPC and DSPC as a combination. The second generation, lysolipid thermally sensitive liposomes (LTSL) technology, has been developed with incorporation of lysolipids that form stabilized defects at phase transition temperature. LTSL maintains certain favorable attributes:

High percentage of lysolipids incorporation;

Minimum leakage for therapeutical drugs encapsulation;

Ultrafast drug release upon heating (3.5 times enhanced compared to TTSL). For example, ThermoDox, a commonly used LTSL drug for cancer, has been reported to release 100% of the encapsulated doxorubicin within 30s;

First and most successful formulation for intravascular drug release.

How does continental drift affect living organisms? check all that apply. view available hint(s) check all that apply. it may ca
Dmitriy789 [7]
The continental drift affects living organisms in that it causes changes in climates which puts selective pressure on organisms, causes changes in habitats, including when large amounts of shallow marine habitat were lost in the formation of Pangea. Additionally continental drift may cause an increase or decrease in competition among different species and also it happens so slowly that it does not affect living organisms

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statemen
podryga [215]

Answer:

<u>Light microscope</u>:

  • use a beam of light to produce magnified images
  • can be used to examine living cells and tissues

<u>Scanning electron microscope</u>:

  • use a beam of electrons to produce magnified images
  • can be used to examine DNA
  • can be used to examine cells

<u>Transmission electron microscope</u>:

  • use a beam of electrons to produce magnified images
  • can be used to examine DNA
  • can be used to examine cells

Explanation:

Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.

Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:

  1. <u>Scanning electron microscope(SEM): </u>an electron beam passes over the specimen's surface and displaces electrons which are then focused on  a screen to form an image. Images appear in 3-D
  2. <u>Transmission electron microscope: </u>electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D
