- Using two centrifuges (A and B), with maximumspeeds of 1500 rpm (r = 8 cm) and 3000 rpm(r = 8 cm), respectively, construct a separationscheme for separating three subcellular structureswith the following xg requirements:• PAT – 150 xg• SAT – 120,000 xg• HAT – 650 xgCalculate the elution volume of blue dextran (blue), myoglobin (red), and Bromocresol purple (purple) in the gel filtration chromatography below with a flow rate of 2.5 mL/min. (Take note that the black colored test tubes represent colorless eluents)For this exercise, an electron micrograph of secretory cells of the anterior pituitary is being used (Sandborn, E.B. (1970) Cells and Tissues by Light and Electron Microscopy, New York, New York: Academic Press, Inc.). The image originally measured 18.7 cm wide and 18.5 cm high with a magnification of 5200x. Given the width of the original micrograph at 18.7cm, what is the true width of unmagnified image? Show calculations.
- A sample of a protein is analyzed by CE using a neutral-coated capillary with a total length of 25.0 cm and a distance to the detector of 22.0 cm. Using an applied voltage of 20.0 kV, the protein was detected at a migration time of 16.2 min. The diffusion coefficient for the protein is 2.4 x 10-7 cm?/s. (a) Calculate the apparent electrophoretic mobility of the protein. (b) Calculate the expected number of theoretical plates for the analysis.Electrophoretic flow and electroosmotic flow (EOF) plays an important role in capillary electrophoresis (CE) for ions movement. Explain the differences between electrophoretic flow and EOF. b) Suggest two different approaches (other than reducing the voltage) to reduce the electroosmotic flow. c) Three water soluble vitamins: niacinamide (a neutral compound), riboflavin (a neutral compound) and thiamine (a cation) were separated by micellar electrokinetic capillary chromatography (MEKC) in 15 mM borate buffer (pH 8) with 50 mM sodium dodecyl sulfate. The migration times were niacinamide (7.5 min), riboflavin (12.8 min) and thiamine (13.9 min) Explain why these vitamins were separated using MEKC. Explain why niacinamide and riboflavin (both are neutral compounds) have different migration times. (i) With the aid of a diagram, differentiate flow profile of electroosmotic flow (EOF) and laminar flow. (ii) Discuss the effect of both flows in term of peak resolution.You intend to make Universal Precaution available to patients admitted to the RICU: https://www.youtube.com/watch?v=wR25COr2FSs Give the complete sequence and description of proper PPE donning in the RICU during COVID, using a flow chart.

Round your answer to 2 decimal places Cockroft Gault equation: [ X (140-age) x (weight in kg)] / serum creatinine (in micromole/L) Where X = 1.04 for females and X = 1.23 for malesOsmotic experiment is done using equivalent dilutions of 2% urea. Note the erythrocyte membrane permeability constants (P) for urea, sodium (Na+) and chloride ions (Cl-) are 152, 0.25 and 0.1 x 10-4 cm.s-1, respectively. Select all of the following which apply. The permeability constants indicate that red blood cell membranes are much more permeable to urea, thus urea will enter the cells (a permeating solute) and exerts an osmotic effect with water leaving the cells. 1% NaCl is equivalent to 2% urea, because NaCl dissociates into Na+ and Cl-, thus resulting in a solution of the same osmolarity as the 2% urea, which does not dissociate. The permeability constants indicate that red blood cell membranes are much more permeable to urea, thus urea will enter the cells (a permeating solute) and does not exert an osmotic effect. The permeability constants indicate that red blood cell membranes are much less permeable to urea, thus urea will not enter the cells (a…
- A 12cm length of dialysis tubuing was prepared and filled with 10ml of 0.9% sodium chloride, 5% egg alubumin and 5% glucose solution. The tubing is placed in a beaker that contains a solution of 5% sodium chloride, 20% egg albumin and 20% glucose. The sac is permeable to glucose and sodium chloride and imperanle to egg albumin. State the direction of movement for the following: Sodium chloride: Egg albumin: Glucose: Water:r^2=6Dt , where D is the diffusion coefficient of thediffusing object and t is the time that the object is allowed to diffuse. If the diffusion coefficient, D, of a small protein is 5 x 10^-10 m2 s-1, how long (on average) does ittake for the protein to diffuse across a parasitic wasp that is 189 um long ?An 84 year old male patient has been given a loading dose of digoxin of 298 micrograms in divided doses by intravenous infusion. He has a creatinine clearance (Ccr) of 34 ml / min. What is the maintenance dose (in micrograms) that this patient should receive? Round your answer to the nearest whole number. Use the formula provided to calculate the maintenance dose. Maintenance Dose = Peak body stores x % daily loss 100 Where: Peak Body Stores = Loading Dose % Daily Loss = 14 + Creatinine clearance (Ccr) 5
