Major drawbacks in the procedure developed by the Yale group. Introduction: Scientists at Yale University produced artificially grown tissue-engineered lungs in the laboratory. They anesthetized a group of adult rats, removed their left lung through surgical procedure, and replaced it with artificially grown lungs. The implanted lung tissues were able to exchange gases for about two hours at a similar rate as normal lungs.

Expert Solution & Answer

Explanation of Solution

The Yale group developed a method to transplant artificially grown lungs in animals. The major drawbacks of the procedure are as follows:

1)

The Yale group carried out the experiment on rats. The implanted artificially grown lung was only able to exchange gases at a normal rate for only two hours.

2)

This might not work on humans as organ systems in humans are regulated by several factors.

3)

The experiment was only successful in laboratory conditions. It is not possible to mimic the sterile environment after the implantation.

Conclusion

Artificially grown lungs by Yale group functioned properly for only two hours and that too under sterile laboratory conditions. The procedure may not work on humans.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
