You need to grow heart cells in artificial environment. What basic chemicals and facilities will you need to grow heart cells in vitro?

Bio-sensor is a device consisting of immobilized layer of biological material such as_______.a) Enzyme, antibody, hormone, nucleic acids b) Enzyme, gene, antigen, hormone c) Nucleic acid, formic acid, acetic acid, tartaric acid d) Hormone, nucleic acid, enzyme, gene.

A small tumor is excised from a patient's body by a biopsy. A clinical cytopathologist wants to examine the shape, size, and arrangement of the cells within the tumor by routine histology (the study of tissues) by fixing and staining them with hematoxylin and eosin. The best microscopic technique to use would be: O bright-field microscopy O phase contrast microscopy O fluorescence microscopy. O All of the other can be used O DIC microscopy

Covid-19 patients may develop acute pulmonary edema (fluid retention in the lungs), and furosemide is often used to treat it.  Another potential complication of covid-19 is acute kidney damage. Possible causes include hypoxia, blood clots and inflammation. To evaluate a patient for kidney damage, a medical team took blood samples and placed a catheter to collect urine for 24 hrs. Here are some results: Plasma creatinine: 50 mg/100 mL plasma Urine creatinine: 40.8 mg/mL urine Urine production: 1.5 L in 24 hr   1. What was the patient's creatinine clearance in mL/min? (Creatinine clearance = excretion rate of creatinine/plasma concentration creatinine). Show your work.

What are some challenges that you foresee when implementing Precision Medicine (which includes Pharmacogenomics and Immunogenomics as well as Risk Screenings for certain cancers)?  This can include ethical, financial, social, legal, etc. challenges.  Please provide some examples when discussing your identified challenges.  How might you tackle these challenges you comment on above?  How might your solutions influence/impact the patient when utilizing Precision Medicine?

what is the frequency of the rarest variant you can detect during deep sequencing of a tumor cell if you coverage is 250X? - 0.5% - 0.4% - 25% - 4%

When using combination antibiotic therapy, it is important to administer drugs that work synergistically as possible. Which of the following represents a combination with known synergism? A beta-lactam and an aminoglycoside A penicillin and a cephalosporin Two drugs in which the second drug will displace the first from plasma protein-binding sites. Two drugs that are eliminated by different routes Two drugs that work on the same step in a metabolic pathway.

(e) Two ADP agonists (drugs) were also found to bind to platelets: 2-methylthio-ADP bound with a Kp of 7 µM and 2-(3-aminopropylthio)-ADP bound with a Kp of 200 µM. Can these drugs effectively compete with ADP for binding to platelets? Explain your answer.

First, we will build a model for the total amount of drugs in the gut. At time \(t = 0\), \(10mg\) of the drug is present in the gut. From the gut, it passes slowly into the blood. The passage of the drug to the blood has first-order kinetics; that is, every hour \(42\%\) of the drug remaining in the gut is passed from the gut into the blood. No more pills are taken, so no extra drug is added to the gut.   Let \(a_t\) be the sequence representing the amount of Adderall XR in the patient’s gut \(t\) hours after the pill was taken. Write down a recursion relation for \(a_t\).   Find an explicit formula for \(a_t\).   Calculate the time at which the amount of drug remaining in the gut drops to \(1\%\) of its starting value; that is, find \(t\) for which \[a_t = 0.01a_0\] Find \(\lim_{t\to\infty}a_t\), what does it represent?   Now let’s build a model for the amount of drug in the patient’s blood. Define another sequence \(b_t\) that represents the amount of Adderall XR in the patient’s…
