Why is hyperthermia considered a beneficial adjunct to radiotherapy and chemotherapy?
|
It makes cancer cells more susceptible to other treatments. |
|
Hypothermia is helpful for the efficiency of radiotherapy. |

Considering the physics of heat transfer, why is controlling hyperthermia challenging during treatment?
|
Human tissue has varying thermal conductivities which affect heat distribution. |
|
Different thermal conductivities around different regions make it difficult to control hyperthermia. |
Heat naturally transfers from hot to cool regions and because our bodies tumors or tissues have different thermal conductivities, the heating is inconsistent to keep in the therapeutic temperature. |

What is a significant potential side effect of whole-body hyperthermia?
|
Systemic stress affecting major organs |
|
From the side effects section it listed nausea, diarrhea, or problems with the heart, blood vessels, and major organs. |
In severe cases it could affect the major organs when it leads to problems associated with the heart or blood vessels. The other options 1,3,4,5 are not particularly negative side effects either. A report (Bull et al., 1989, Kerner et al., 1999) shows that with various anesthestics, there is an entirely different range of toxic effects from the systemic stress. |

What type of hyperthermia uses applicators inserted into or near a body cavity to deliver heat?
|
Endocavitary hyperthermia |
|
The row of Intraluminal or endocavitary approach says that the application is to the near body cavities to deliver heat. |
External approach are on areas just below the skin, and interstitial treats the tumors deep inside, so we know that it is endocavitary because it treats tumors within the body or near body cavities where endocavitary antennas were inserted. |

Which type of hyperthermia involves heating a larger region or the whole body?
|
Whole-body hyperthermia |
|
Whole body hyperthermia is applied to treat metastatic tumor that has spread throughout the body. |
An example of the patient who raised the body heat within 180min between 37.5 to 42 degrees celcius and the power distribution was influenced by 3 dimensional anatomy. |

What is the main challenge of using hyperthermia in cancer treatment?
|
Reaching and maintaining the required temperature in the target area. |
|
It is difficult to maintain consistent heat in a target area in order for it to be therapeutic. |
Temperatures too low will not be sufficient enough to be effective, while too high may damage internal tissues, so it must be maintained for a certain amount of time. |

Hyperthermia is often used in combination with which of the following treatments?
|
Radiotherapy and chemotherapy |
|
Hyperthermia enhances the radiotherapy activity and tissue perfusion for chemotherapy. |
With heat, chemical reaction in chemotherapy is sped up and in radiotherapy, ionizing radiation is increased by three times. |

What is the primary benefit of using hyperthermia in cancer treatment?
|
It kills cancer cells with minimal damage to normal cells. |
|
The introduction states that it elevates the body temperature to kill cancerous cells with minimal injury to normal cells. |
Its main mechanism is to kill the cancer cells by destroying proteins and the structure within cells and it is safe as long as the temperature is maintained. |

Which method is used to apply heat directly to a tumor in local hyperthermia?
|
Microwaves |
|
Microwaves incorporate heat like the section on local hyperthermia said. |
Antennas or applicators emitting microwaves or radiowaves, the superficial tumors can be heated. |

What is hyperthermia commonly used to treat?
|
Cancer |
|
It has been mentioned several times that it is used to destroy cancer cells and be used alongside other forms of cancer therapy. |
It kills cancer cells or make tumor cells more prone to radiation. It is a method of using heat to treat cancer as many studies included in the article have reported results on hyperthermia. |

What is the importance of the photodiode array detector in the HMLC technique used in the study?
|
It detects the presence of pesticides across a spectrum of wavelengths. |
|
HMLC detects the pesticides through selective sorbents and chromotographic separation. |
I can tell from the passage that it emphasizes separation, analytical determination, and using selective chromotographic sorbents. |

Considering the environmental impacts discussed, why is the HMLC method considered 'green'?
|
It involves less waste and uses low-toxicity solvents. |
|
It minimizes the reagent use and uses techniques to reduce waste along with using safer or sustainable solvents. |
The passage emphasizes on green analytical chemistry. |
