- In one square of a hemacytometer you count 55 cells. What is the approximate concentration of cells per l (liter) in this sample? (note that "^" means superscript, e.g. 10^2 means 10 to the 2nd power) The options are 5.5 X 10^5 2.75 X 10^8 5.5 X 10^8 2.75 X 10^5A patient being treated for metastatic carcinoma was found to have a white cell count of 5 x 10°/L with 5 metarubricytes (nucleated red cells) per 100 WBCs. What is the corrected white cell count for this patient?Correlation between phagocytic activity of neutrophils and age. Notable inverse correlation between PAN and age. why is that ? explain how to read chart?
- If you made a hematocrit in two tubes. Tube A is made of 0.60M NaCl, and Tube B is made of 1.00M of NaCl, describe how the cell would respond in these solutions? Which tube would have a lower hematocrit?A 6 month old pediatric patient is B-negative. She has received a unit of platelet pheresis that appeared to be bloody. the estimated blood volume in the unit of platelets is estimated to be 5 mLs. Please calculate the dose of RhLg (standard) to be injected to this patient to prevent stimulation of alloanti-D (HINT: It's estimated that 5mL of red blood cells are in the unit of platelets, so think of the 5 mL volume of red blood cells as being "packed cells" rather than whole blood) Need answer ASAP and in short .I will make your life a bit easier and not make you count four additional grids. So let's assume this was a random, relatively uniform sample and arbitrarily assign the other four squares to the exact same number of red blood cells. What is the Total red blood cell count? Calculate it as (#RBC you counted *5)*10,000 Is you answer normal? Edit View Insert Format Tools Table Paragraph v | в I U 12pt v
- please help explain this chart ( discribe in detail what it is saying)It was found empirically that Bill would stay healthy and have no significant infections if his IgG level were maintained at 600 mg/dl of plasma. He was prescribed 10g of gamma globulin every week to maintain that level. How was the dose calculated? (Explain what considerations went into determining this dose regimen)The growth of hybridoma cells, producing a monoclonal antibody, was monitored for 4 and a half days, and the results obtained are listed in the following table: time (days) nº cel/mL x 106 ln nº cel 0 0,45 -0,79851 0,2 0,52 -0,65393 0,5 0,65 -0,43078 1 0,81 -0,21072 1,5 1,22 0,198851 2 1,77 0,57098 2,5 2,13 0,756122 3 3,55 1,266948 3,5 4,02 1,391282 4 3,77 1,327075 4,5 2,2 0,788457 What is the maximum specific rate (µmax) of growth of these cells per day? what is the doubling time of these cells (in days)?
- Draw a standard curve (using linear graph paper) of A595 (Y axis) versus μg protein for tubes 1-6 (standards) and use this to determine the amount of protein in each of the fractions (serum, B and crude IgG). Calculate the total amount of protein in the starting serum and the amount recovered in each of fraction B and the IgG fraction (you need to know the total volumes of these samples). The volume recorded for fraction c was 1ml and fraction b was 11ml. Please I need helpThe name of the reagent for performing the prothrombin time test is: Question 7 options: A) thromboplastin and actin B) tissue factor and calcium C) phospholipid and calcium D) thromboplastin and calciuma) Hemoglobin accounts for 95% of the protein in red blood cells. If you Google the number of hemoglobin molecules in a RBC, most sources state 250-270 million hemoglobin molecules. If hemoglobin has a molecular weight of 67,000 Da, what is the concentration of hemoglobin in RBCs? Show your work and show your units. Use dimensional analysis to have your final answer in moles per liter. B) The hemoglobin molecule is nearly spherical with a diameter of 55 Angstroms. You can look at the 3D structure of human hemoglobin on the RCSB PDB website. Calculate the volume of a hemoglobin molecule, and can the number of hemoglobin molecules quoted in Question a actually fit into one red blood cell?
