Case Studies An 18-year-old male high school student who had a 4-year history of diabetes mellitus was brought to the emergency department because of excessive drowsiness, vomiting. and diarrhea. His diabetes had been well controlled with 40 units of NPH insulin daily until several days ago when he developed excessive thirst and polyuria. For the past 3 days, he has also had headaches, myalgia, and a low-grade fever. Diarrhea and vomiting began 1 day ago Chemistry Test Results Sodium 126 mmol/L Urinalysis Results Specific 1.012 gravity pH 5.0 Glucose 4+ Ketone Large Potassium Chloride Bicarbonate Plasma glucose 6.1 mmol/L 87 mmol/L 6 mmol/L 600 mg/dL BUN Creatinine Serum ketones 48 mg/dL. 2.0 mg/dL 4+ 1.

1. Penicillin is hydrolyzed and thereby rendered inactive penicillinase, an enzyme present in some penicillin-resistant bacteria. The molecular weight of this enzyme in Staphylococcus aureus is 29.6 kilo Daltons (29.6 kg/mole or 29,600 g/mole or 29,600 ng/nmole) The amount of penicillin hydrolyzed in 2 minute in a 10-mL solution containing 109 g (1 ng) of purified penicillinase was measured as a function of the concentration of penicillin. Assume that the concentration of penicillin does not change appreciably during the assay. [Hint: Convert everything to the same concentration terms] Show all calculations and include spreadsheets and graphs to determine Km, Vmax and kcat for this enzyme. Make sure your final answers have correct units. [Another hint: Note that [S] and amount hydrolyzed are already in concentration terms. So you don't need to worry about the volume for calculating [S] and V. ] Penicillin concentration (microM) Amount hydrolyzed (nanoM) 1 110 3 250 5 340 10 450 30 580…

6. A 190 lb worker in a factory received an exposure to AB which has a molecular weight (MW) of 278 g/mole. AB is completely metabolized in the body to A (MW 194) and B. A is completely excreted in the urine and B is further metabolized to five different compounds. A 24-hr total urine sample was 2060 ml, Analysis showed the concentration of A in the urine was 1.28 ng/mL What was the absorbed dose of AB in ug/kg body wt?

You have just started working in an Urgent Care Clinic as a nurse.  Mom brings in her 3 year old little boy, Brandon.  Mom states that Brandon has been having fever up to 104F and he isn't eating or drinking anything because he feels very sick to his stomach, not to mention crabby!  He's also been pulling a lot at his right ear and sounds congested.  At the last well visit with the Pediatrician (about 2 weeks ago), Mom states that Brandon weighed 32 pounds. On exam today, his weight is 12.5 kg.  Additionally his eyes are darkened and sunken, his mouth is dry with some white crusting around the lips.  His temperature is 39C, other vitals signs are normal.  Though he looks ill he appears to be medically stable.  The doctor rushes in, quickly exams Brandon, diagnoses him with otitis media and then barks off orders to you that you then need to convey accurately to Mom.  The orders include:  push fluids, ibuprofen 10mg/kg every 6 hours if temp > 38C, and begin taking a 10-day course of…

amanda found an article that stated 5 mg/ml of nicotine (mw 162.23 g/mol) enters the blood stream after smoking a hookah pen. she wants to investigate the potential hazards of such high amount of nicotine in the blood. what molar concentration should she use to replicate this phenomena in vitro.

You have come down with a nasty cold and would like to understand why the virus thatinfected you is making you feel so lousy. With a few facts given here, you can show that theinfected cells are now very full of virus particles, resulting in your current condition.A. Calculate the volume of a eukaryotic cell, in liters (L).B. Calculate the concentration, in Molarity, M, of a single virus within that cell. Note: this is theconcentration of any single molecule within a cell.C. Calculate the concentration, in Molarity, M, of 105 (100,000) virus particles —a typicalnumber produced by a viral infection — within that cell.D. If each virus particle is 100 nm in diameter, calculate the “excluded volume” — the spaceoccupied by those 100,000 virus particles. Compare this to the volume of the cell. In otherwords, what fraction of the cells total volume is currently being occupied by virus particles?E. Estimate the average distance between the 105 virus particles in the eukaryotic cell.
