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.

Verdich [7]
<span>A human body is composed of muscles. Without it, the human body cannot function and will die. </span>

There are three types of muscle tissues: Skeletal muscle, Cardiac muscle, and Smooth muscle.

The skeletal muscle aids in the movement of the human skeleton. The 600 skeletal muscles make up 40 % of our body weight and are reliant on the signals released by our nervous system to start moving.

<span>Cardiac muscles are those muscles which encloses our hearts. They are involuntary muscles which pumps blood throughout our bodies by creating steady and rythmic pulsing. They also make our heart contract by producing electrical impulses. </span>

<span>Smooth muscles are found in the walls of blood vessels, respiratory passageways, and hollow organs. Its contracting movement is wavelike and it helps in the transfer of food through our stomachs or urine through our bladder. </span>

<span>These muscles responds to nerve impulses and other stimuli.</span>

Sakura tested the pH of several solutions. Which substance are acidic?
stealth61 [152]

Answer: cola-flavored soda: 2.6

cranberry juice: 2.9

pickle juice: 5.5

Explanation:

The substances given are:

cola-flavored soda: 2.6

cranberry juice: 2.9

dish soap: 7.3

pickle juice: 5.5

seawater: 8.0

lye soap: 13.0

Based on a pH scale, an acidic solution is one that has a pH that is below 7, a solution is neutral if the pH is 7 while a basic solution has a pH of above 7.

Therefore, the acidic substance will be:

cola-flavored soda: 2.6

cranberry juice: 2.9

pickle juice: 5.5
