5. Below is a table showing composition data for clove oil, obtained using two different detection methods (with the same sample), FID and mass spectrometry. Explain why the composition (based on relative peak areas of the GC trace) is different for these data sets. Are either of these the “real” composition of the clove oil?

According to the World Health Organization (WHO), Infertility is the inability to conceive a child. A couple may be considered infertile if, after two years of regular sexual intercourse, without contraception, the woman has not become pregnant (and there is no other reason, such as breastfeeding or postpartum amenorrhoea). Primary infertility is infertility in a couple who have never had a child. Secondary infertility is failure to conceive following a previous pregnancy. Infertility may be caused by infection in the man or woman, but often there is no obvious underlying cause.

Evolution occurs as a result of natural selection. You have looked into the fossil evidence of the transition as well as the genetic basis of the genes responsible. For this section, theorize and describe how natural selection selected for the adaptation and why it was successful for the organisms in question.

Case #2
A 30 year old female patient comes to your retail pharmacy to pick up a prescription for Tylenol #3 (acetaminophen + codeine) for pain control. You enter the prescription into the computer system and the computer’s interaction checker flags an interaction between Tylenol #3 and the patient’s fluoxetine prescription. Answer questions 1-3 regarding this case.
. What would you expect to see if you give codeine to: a) a poor metabolizer for the enzym CYP2D6 and b) an ultra-rapid metabolizer of the enzyme CYP2D6.
Case #3
C.G., A 29 year-old female (yof) patient, presents for inpatient care. You are working as a staff pharmacist in the hospital pharmacy and are asked to verify/fill her prescriptions. Her current medications are for rifampin, nifedipine, amitriptyline, and fluoxetine, valproate sodium, and lamotrigine. Please identify at least three potential biotransformation-related drug interactions in the scenario above and describe the potential mechanism for the interaction. Describe the expected effect (i.e., increased/decreased parent drug concentration, increased/decreased metabolite concentration).
Interaction #1 & effect on plasma concentrations –
Interaction #2 & effect on plasma concentrations –
Interaction #3 & effect on plasma concentrations -
A week later, C.G. is still in the hospital. She is very hypertensive and the physician elects to start IV propranolol 2 mg. Is this an appropriate dose of propranolol for hypertension management when the patient goes home? If not, why not?
In addition to her hypertension, C.G. developed an arrhythmia. The physician ordered lidocaine to be given IV. Initially, this drug produced a therapeutic plasma concentration (Css total of 4 mg/L). This drug has a high extraction ratio and is highly bound to alpha-1-acid glycoprotein. A few days after starting the drug, the total plasma concentration remained the same, but the free drug concentration was found to be increased.
What is a potential explanation for this change in free drug concentration?
Why would total concentration stay the same? What factors would alter the total drug concentration (Css) of lidocaine?

Your evil roommate creates a device that slows the rate of rotation of planet Earth from a 24-hour period of rotation to a 48-hour period of rotation. Holy cow evil roommate, this is extreme! Given that each day is now 48 hours long, predict how the difference between daytime high and nighttime low temperatures at the equator would change. How do you think this would affect the plants growing at the equator?
