effect of different feeding schedules on the survival and neural differentiation of human embryonic and induced pluripotent stem
Serga [27]

The survival or neuronal development of human embryonic or human induced pluripotent stem cells is not improved by feeding them more than five days per week.

<h3>Why does feeding not increase neuronal differentiation or cell survival?</h3>

An induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) can differentiate into any form of specialized human cell, ESC/iPSC-derived cell types have a lot of potential for use in regenerative medicine.

Neuroscience research can benefit from neural culture of human pluripotent stem cells. However, it is unknown what the ideal feeding schedule for these in vitro systems should be. Human embryonic and induced pluripotent stem cells were cultivated with medium exchange schedules of five, six, or seven days per week during two months of differentiation. We assessed the survival and neural differentiation characteristics of these cells. Through this period of culture, neither human pluripotent cell type showed any appreciable alterations in cell counts or indicators of brain development. We come to the conclusion that feeding this culture system more than five days a week is unlikely to be advantageous.

The Waldorf family was caught in a fire but escaped. Unfortunately, the father and daughter suffered burns. The father had secon
SVEN [57.7K]

Answer and Explanation:

The father had 54% of the body covered by burns, since a little more than half of his body was burned. In addition, to calculate the percentage of body burn, the following values are considered: head, arms and legs - 9% torso front - 18% torso back - 18%. In addition, the father feels little pain in his legs (which had worse burns) because the third degree burn destroys the nerve endings, while the second degree burn only damages these endings promoting intense pain.

The daughter had 9% of her body burned by first degree burns, which corresponds to her lower limbs. These burns involve the skin and the epidermis, for this reason, we can say that the legs are the part of the daughter's body that has compromised hair and epidermis.
