0. We Merged...Now What?

   Earlier this month, your company, a running equipment designer and manufacturer called Runners Paradise, merged with a smaller clothing design company called ActiveLeak. Your company initiated the buyout because of the excellent design team at ActiveLeak and their brand recognition, specifically for their MP3-integrated running shorts. Runners Paradise has thirty-five employees and ActiveLeak has ten employees. At ActiveLeak, the owner, who often was too busy doing other tasks, handled the HRM roles. As a result, ActiveLeak has no strategic plan, and you are wondering if you should develop a strategic plan, given this change. Here are the things you have accomplished so far:

   • Reviewed compensation and adjusted salaries for the sake of fairness. Communicated this to all affected employees.

   • Developed job requirements for current and new jobs.

   • Had each old and new employee fill out a skills inventory Excel document, which has been merged into a database.

Questions:

1. Determine human resource needs.

2. Determine the recruiting strategy.

3. Select employees.

Write a class (and a client class to test it) that encapsulates a tic-tac-toe board. A tic-tac-toe board looks like a table of three rows and three columns partially or completely filled with the characters X and O. At any point, a cell of that table could be empty or could contain an X or an O. You should have one instance variable, a two-dimensional array of values representing the tic-tac-toe board.

This game should involve one human player vs. the computer. At the start of each game, randomly select if the computer will play X or O and who (i.e. human or computer) will make the first move.

Your default constructor should instantiate the array so that it represents an empty board.

You should include the following methods:

a method that generates a valid play by the computer and displays the board after each play.

a method that requests a valid play from the human and displays the board after each play.

a method to display the tic-tac-toe board.

a method checking if a player has won based on the contents of the board; this method takes no parameter. It returns X if the "X player" has won, O if the "O player" has won, T if the game was a tie. A player wins if he or she has placed an X (or an O) in all cells in a row, all cells in a column, or all cells in one of the diagonals.

NOTE: Be sure to display the board after each move. You must provide clear prompts for the human player to select a space on the tic-tac-toe board.

Input Validation: Verify that all moves by the human player are to a valid space on the tic-tac-toe board. An incorrect choice should not halt or terminate the game.

Can You please Answer the question using R studio and R cloud

Telomeres are complexes of DNA and protein that cap chromosomal ends. They consist of the same short DNA sequence TTAGGG repeated over and over again. They tend to shorted with cell divisions and with advancing cellular age, which will lead to chromosome instability or apoptosis (programmed cell death).

Eukaryotic cells have the ability to reverse telomere shortening by expressing telomerase, an enzyme that extends the telomeres of chromosomes. The level of telomerase activity is important in determining telomere length in aging cells and cancer cells.

One study of telomere length (measured as a ratio compared to a standard) were conducted and results were reported in the following table:

1. Calculate the linear correlation between telomere length and the cellular aging. Is there asignificant relationship. (10 pts)
2. Use a different method from the one used in part (a) to calculate the linear correlation between telomere length and the cellular aging. Is there a significant relationship? (5 pts)
3. Estimate the slope and intercept of the least square regression line, with the telomerase activity as independent variable. (10 pts)
4. Using the t test to test the null hypothesis of zero slope at the significance level of a = 0.05. (10 pts)
5. What does MS _residual measure? What is the value of it in this study? (5 pts)
6. Calculate the R² statistic. What does it measure? (5 pts)
7. If a sample of cells has the telomerase activity 0.60 μmol/min, predict the length of telomere (as relative ratio) in those cells. (5 pts)

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?

Case Study – Atherosclorosis Francois was shoveling some light snow off of the driveway when he suddenly experienced a severe chest pain. He felt a weight on his chest and was having trouble breathing. A stab of pain also radiated across the left side of his neck and down his left arm. His wife called 911 and an ambulance picked him up and brought him to the local hospital. The resident told him that he was suffering from angina pectoris. As he lay there resting, the pain subsided and he began paying attention as the doctor asked him some questions and did a few basic measurements. He was 52 years old, 5’10” tall and weighed 210 lbs. His girth at the waist was 42 inches. An MRI of his neck revealed artherosclerotic plaque buildup in his carotid arteries. He told the doctor that he smoked about 3 packs of cigarettes per week, did not drink alcohol and had a relatively sedentary lifestyle. They took a blood sample and did a variety of tests.

The results follow: Low density lipoprotein was 210mg/dl

Triglycerides were 195mg/dl

High density lipoprotein was 28mg/dl

Creatine kinase was elevated The doctor set him home the next day with a prescription for a statin drug and instructions to get regular, moderate exercise and carefully monitor his diet. He was told to try to get his BMI down to 25 and his girth to 36”.

2. What is Francois’ BMI? What does the combination of BMI and waist girth tell you about his risk factors for cardiovascular disease?

3. What do the LDL, triglyceride and HDL measurements tell you about his risk factors? What other risk factors does he have?

4. What does the elevated CPK mean? How did this enzyme get into his plasma?

5. What are statins and how do they work?

6. Give three examples of pathologies in which there is an upregulation of RAAS. Next to each one explain your reasoning.

7. How would high levels of angiotensin II (Ang II) affect someone with hypertension?

Part II – Grandpa’s Medications

“Now, what about your grandfather’s medications? He’s taking lisinopril and furosemide. How do those interact with your RAAS system on this diagram that you’ve made?” asked Mom.

“My professor, Dr. Sven, did mention how certain medications disrupt the system and lower blood pressure, which is why grandpa is on these medications. But I’m not sure what drug classes those particular medications belong to.” Arie picked up her iPhone and said, “Hey Siri! What is lisinopril?”

An automated friendly voice boomed, “Lisinopril is a medication of the angiotensin-converting enzyme inhibitor class used to treat high blood pressure, heart failure and after heart attacks. For high blood pressure it is usually a first line treatment…” (Wikipedia, Lisinopril, 2020).

“Ah! Lisinopril is an ACE inhibitor, and furosemide is a diuretic. Ok, now I get it. Let me show you how these drugs disrupt the RAAS pathway and lower Grandpa’s blood pressure.”

Questions

1. Explain why ACE inhibitors (ACEi) and angiotensin receptor blockers (ARB) are prescribed to treat hypertension and heart failure.

2. A drug that amplifies the effect of bradykinin would have what effect? What diseases could it be prescribed to treat?

3. Would a patient taking an ARB have the same vasodilation effect via bradykinin as a patient taking an ACE inhibitor?

4. Spironolactone is a drug that blocks the aldosterone receptor in the renal collecting tubule. How would the sodium and potassium levels in the urine change after a patient is placed on spironolactone? Based on these changes, what are possible metabolic adverse effects of the drug?
