Think about the job of your dreams (epidemiologist). How might you use research writing skills to perform that job? Discuss the ways in which strong researching, organizing, writing, and critical thinking skills could help you succeed at being epidemiologist.

Multitest systems use a series of miniaturized biochemical tests to determine the identity of an unknown organism. Compared to using individual test tubes for these same tests, multitest systems __________. Multitest systems use a series of miniaturized biochemical tests to determine the identity of an unknown organism. Compared to using individual test tubes for these same tests, multitest systems __________. are more resistant to contamination use less media and reagents require a shorter incubation period generate results that are easier to interpret

Researchers are developing a new screening test for a disease that will be less invasive then the current "gold standard" screening test. The disease is highly communicable if treatment is delayed thus researchers will want to prioritize the new screening test to minimize the number of Researchers are developing a new screening test for a disease that will be less invasive then the current "gold standard" screening test.

Which tool/tools from the list can be used in a paternity (who's the father) test? Pregnancy test Adenovirus ELISA CRISPR PCR

From the xray how can you say that it is the xray of a child rather than a grown man.

Pick a specific microbiome (i.e. skin, mouth, gut, reproductive) and discuss interesting points and how it is important to human health/diversity/etc. Here you can discuss any aspect of the microbiome that you like. Whatever is of most interest to you personally for example the uniqueness of an individual’s microbiome or disease states due to disruptions in bacterial communities, etc. Find a recent (2015 or newer) primary research article that investigates some aspect of the microbiome environment that you discussed in question 2 and discuss the findings and how it has increased our understanding of the microbiome.

The figure below shows the number of bacteria/ml in a series of patient's samples collected and cultured over time, and the resistance of these bacteria to a given antibiotic. This shows all of the following EXCEPT: Bacteria (number/ml) 108 107 106 105 104 103 0 Initiation of antibiotic therapy Bacteria count 1 2 3 5 6 Days Copyright © 2007 Pearson Education, Inc., publishing as Benjamin Cummings. Antibiotic resistance of bacterial population measured by amount of antibiotic needed to control growth 4 7 8 9 10 11 50 40 30 6 Antibiotic resistance (mg/ml) After an initial decline, the number of bacteria eventually rises again as antibiotic- resistant bacteria emerge and multiply At the beginning of antibiotic therapy, most of the bacteria were already resistant to 50 mg/ml of the antibiotic After about 5 days of treatment, the bacteria in the patient's samples were resistant to 50 mg/ml of the antibiotic None of the other four answers (All of these statements are true)

Following is the data and notice that it is a terrible idea to culture hMSCs longer than 10 days. You’re strongly Days # cells0 50001 75002 125003 125004 218005 287006 530007 1143008 1653009 19200010 19200011 11680012 8950013 8830014 78300 Part1 You are working for a start-up that is pursuing a clinical trial. The trial involves grafting hMSCs intopatients suffering from interveterbral disc disease using a degradable polymer scaffold. You are going to 3Dprint a porous cylindrical scaffold that is 2 cm in radius and 1 cm in height (matching the dimensions of adegenerated disc). Assume a porosity of 50%. You will fill available volume of the scaffold with hMSCs at adensity of 1 million cells per cm3. Based on the data above, what starting number of cells will you use andhow long will it take you to get enough cells for the trial? Part2The trial is a failure (patients did not report any reduction in back pain). Your team wants to try againusing 85% hMSCs and 15% nucleus pulposus cells .…

Pick either of these media: (EMB or HE) and describe (again, in your own words) how the chemical ingredients in that medium work to make it both "selective" as well as "differential"
