What specific markers were used to assess the purity of the STEM-PD batch?
|
SOX1 and PAX6 |
|
Because they appear in cells that are not the right kind for final treatment. by checking for these, they can removed the wrong cells to make the batch pure. |
The goal of this process is to ensure the final product is specific by identifying unwanted cell types through unique markers is the standard way to guarantee the batch is safe and effective for patients. |

What is the primary function of AI in the medical imaging industry?
|
To improve diagnostic accuracy and patient outcomes |
|
AI acts like a tool to help doctors look at medical images more effectively. by catching detail that may be missed and make accurate diagnosis for better treatment the patients |
This is based on using advanced computer code to find patterns in medical scans that humans may struggle to identify. it is a supporting element that can be used by doctors for safer, more reliable health decisions. |

Which of the following is a key benefit of AI in radiology noted in the article?
|
Acts as a second medical opinion |
|
Ai are tools to be perceived as "A secondary eye" for doctors. it can check the same scan that a radiologists looks at to make sure nothing important is missed. |
The core idea is that two checks are better than one. Ai is the secondary opinion that can better doctor's confident. |

What does AI literacy refer to according to the article?
|
Understanding and knowledge of AI technology |
|
Having Ai literacy means to know what it is and how it works and how to use it effectively and properly |
It reflects the educational framework of digital literacy, specifically adapted to a basic level of knowledge to navigate it successfully. |

Which factor is NOT listed as influencing the acceptability of AI among healthcare professionals?
|
The color of the AI machines |
|
Thing like trusting the technology, understanding how to ultilize it and fitting it to daily schedule are important for doctors to accept Ai. The colour however foes not affect the results. |
Scientists study why people accept new technology based on how well it performs and how easy it is to ultilize, not on its physical appearance. |

What role does social influence play in AI acceptability in healthcare according to the article?
|
Affects healthcare professionals’ decisions to use AI |
|
What colleagues and superiors opinions on Ai have a huge influence to doctors and nurses. If the opinion is good they are more likely to decide on ulltilizing it. |
This is the idea that people seems to adopt the behaviour of those around them, especially in a professional setting, to met with the standard and expectations to perform. |

What is a perceived threat regarding AI usage in healthcare settings?
|
Concerns about replacing healthcare professionals |
|
Many professional doctors and nurses have had an opinion on Ai, about how eventually they will be replaced by such technology instead of Ai being an assistant. |
It is a natural human fear of being pushed aside by new technology that can perform the same task in mere seconds, which affects how quickly professionals accept new technology. |

According to the article, what is essential for increasing AI acceptability among medical professionals?
|
Designing human-centred AI systems |
|
To make doctors accept ai, it is not enough for the system to be smart or accurate. the ai must be built around the humans using it, fitting flawlessly into their daily life and respecting medical rules. |
Technology in healthcare works best when it is design with the end user in mind. this usually indicates that by combining both the technical performances and human experiences to ensure the tool is really helpful in reality. |

What does the 'system usage' category of AI acceptability factors include according to the article?
|
Factors like value proposition and integration with workflows |
|
The "system usage" category focuses on the actual experiences of intereacting with the ai. this includes whether doctors find the ai valuable for their work and how smoothly it fits into their daily routine. |
People are much more likely to adopt a new tool if it clearly improves their performances and doesn't unnescessarity complicate their normal work habit. |

How does ethicality impact AI acceptability among healthcare professionals?
|
Affects views on AI based on compatibility with professional values |
|
Doctors and nurses base their decisions of ai on whether the technology respects their morals and rules of medicine, especially regarding patient privacy. |
In healthcare, a new tool isn't judged just by its technical skill but by whether it does the right thing for both the patient and doctors. |

What methodological approach did the article emphasize for future AI acceptability studies?
|
Considering user experience and system integration deeply |
|
The authors stress that future research shouldn't look at numbers or theories, it need to carefully study how healthcare workers actually have experience the ai and how well it fits |
A medical tool is only as good at its usability therefore evaluating technology requires looking at the human side of how people interact with it and integrate it to their workplace. |

What is the primary objective of using human embryonic stem cells in treating Parkinson’s disease?
|
To replace lost dopamine neurons. |
|
Parkinson's disease happens when specific brain cells that make dopamine die off. stem cells are used to grow new dopamine making cells to replace the missing ones and restore normal movement control. |
The core theory is regenerative medicine, which uses a stem cells that have the ability to turn into any cell type allowing doctors to specifically grow the exact nerve cells a patient's brain has lost. |

Which animal was used to test the STEM-PD product for safety and efficacy?
|
Rats |
|
before trying the treatment on humans, scientists thoroughly tested the safety and effectiveness of the cells on rats. |
rats are commonly used in medical science to check of the success rate. |

|
9 months |
|
To make sure the treatment was safe, researchers monitored rats for 39 weeks after the cell were transplanted to check for any harmful side effects. |
Before starting human trials, safety studies must last long enough to confirm that the new stem cells will go as expected and not do unexpected things. |

How is the STEM-PD product manufactured?
|
Under GMP-compliant conditions |
|
The STEM-PD product must be made in a strictly controlled environment that follows the rules of GMP (a set of global safety rules) for it to be allowed for human use. |
GMP or Good Manufacturing Practice is the international standard for making sure medicines and cell treatments are made safely and correctly every single time. |

According to the article, what confirmed the safety of the STEM-PD product in rats?
|
There were no adverse effects or tumor formation. |
|
Safety was confirmed because the rats showed no sign of problems and side effect after receiving the treatment. side effects like health problems and tumors. |
Since stem cells can grow into many types of tissues, a main danger is them accidentally forming tumors. if a stem cell did not form tumors, it means they are 'safe'. |

What key finding was noted in the efficacy study of STEM-PD in rats?
|
Transplanted cells reversed motor deficits in rats. |
|
The main goal was to see if the cells worked and the findings showed that the transplanted cells actually helped the rats improve their movement and physical abilities. |
The theory is that if we can replace the dead nerve cells with healthy functioning ones, the brain can once again send the correct signals to control muscles and fix physical symptoms. |

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. |
|
These molecules act like chemical "instructions" during the manufacturing process, telling the stem cells exactly what kind of brain cells to become. |
Just like during natural development in an embryo, cells need specific chemical signals or growth factors to trigger the genes that turn them into specialised dopamine neurons. |

What was a key outcome measured in the preclinical trials for efficacy in rats?
|
Recovery of motor function |
|
Researchers measured how well the rats could move and the improvements of their movements. for an example, a better coordination or reduced shaking. this proves that the therapy was working. |
Because of the main problem in Parkinson's is the loss of movement control, the best way to prove the treatment works is to show that it restore physical movement. |
