Which factor is NOT listed as influencing the acceptability of AI among healthcare professionals?
|
The color of the AI machines |
|
The color of AI machines doesn't affect trust in their performance because it has no impact on the operational results. It might only affect their external appearance or aesthetics. |
To trust the performance of AI machines in the medical field, we must be confident that they will operate without interruptions and be constantly ready for action. The color of the AI machine, however, has no impact on its functionality. |

What is a perceived threat regarding AI usage in healthcare settings?
|
Concerns about replacing healthcare professionals |
|
As we use AI more, the need to hire people for certain jobs decreases because humans have more uncertainties in their work. For example, a person might take leave and not come to work, but AI doesn't need to stop working. |
Concerns about the reduction of human personnel will also increase because AI will come to replace people in jobs. |

According to the article, what is essential for increasing AI acceptability among medical professionals?
|
Ensuring AI systems have high algorithmic performance |
|
We must ensure that the AI we intend to use in the medical field has a very high level of safety before it can be implemented. |
Because if we use AI that is unreliable or inefficient, it will impact patient trust in the hospital and could result in patients not receiving the optimal treatment they deserve. |

What does the 'system usage' category of AI acceptability factors include according to the article?
|
Factors like value proposition and integration with workflows |
|
Each time we use an AI machine, we need to ensure its readiness for the task. |
If AI is not ready for operation or isn't properly maintained and integrated, it could lead to negative consequences. For instance, it might result in incorrect or substandard treatment for patients. |

What is the primary objective of using human embryonic stem cells in treating Parkinson’s disease?
|
To replace lost dopamine neurons. |
|
Parkinson's disease is a slowly progressive brain disorder characterized by the continuous loss of specific neurons in a brain region called the substantia nigra. Symptoms include tremor. |
The aim is to transplant them into the brains of Parkinson's patients to restore dopamine levels and help alleviate their motor symptoms. |

Which animal was used to test the STEM-PD product for safety and efficacy?
|
Rats |
|
To see if the STEM-PD product contains substances harmful to the animal's body, and what its short-term and long-term side effects are. |
Rats have many organ systems and biological processes that are similar to humans, such as the nervous system and rats have significantly lower costs for raising, caring for, and performing procedures on, which makes research possible on a wider scale. |

|
|
|
This is described as 'the first-in-human trial to test the safety and feasibility of using a stem cell product in people with Parkinson's disease,' with a primary objective to assess safety and tolerability. |
STEM stands for Stem Cells, which are a crucial component of this treatment, as the product utilizes human embryonic stem cells (hESCs) to develop into dopamine-producing neurons and PD stands for Parkinson's Disease, which is the disease this product aims to treat. |

How is the STEM-PD product manufactured?
|
Using spontaneous differentiation |
|
This is when stem cells change their state into other types of cells without being specifically stimulated or controlled by researchers, which is often something to be avoided in cell production for therapeutic purposes. |
This involves transforming human pluripotent stem cells (hPSCs) into specific dopamine progenitor cells. |

According to the article, what confirmed the safety of the STEM-PD product in rats?
|
There was biodistribution of cells outside the brain. |
|
A 9-month GLP (Good Laboratory Practice) safety study was conducted to determine if the transplanted cells had biodistributed to other parts of the body beyond the target area in the brain, and the testing was safe. |
The fact that this trial could proceed to human trials indicates that the results regarding cell biodistribution were acceptable and did not raise significant safety concerns. |

What specific markers were used to assess the purity of the STEM-PD batch?
|
OCT4 and NANOG |
|
These are transcription factors that are extremely important in the biology of stem cells. |
They help inhibit the expression of genes involved in differentiation into various cell types, allowing stem cells to remain in an undifferentiated state. |

What role do growth factors like FGF8b and SHH play in the manufacturing process of STEM-PD?
|
They are used in cell patterning for specific neural fates. |
|
FGF8b and SHH are indeed used in cell patterning to define the fate of specific neural cells. |
This is to obtain dopamine progenitor cells exclusively from the midbrain, because these are the specific cells lost in patients with Parkinson's disease. |
