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 .…You got an opportunity to join a professor lab who is working in-vivo model and specifically looking at the dysregulation of mitochondria in liver.

When I read it myself, I do not understand exactly what is meant by the article. It would be nice if you could highlight the important points. You can use them in a figure or diagram to explain. thank you and hava a nice day :) Article: Photodynamic Inactivation of SARS-CoV-2 In addition to drug- and vaccine-based antiviral strategies, photodynamic therapy (PDT) stands as a unique approach to inactivate SARS-CoV-2. Using a light-based method, PDT attacks target cells via the excitation of photosensitive agents, called photosensitizers (PSs), with radiation characterized by a wavelength corresponding to its absorption spectrum to generate reactive oxygen species (ROS) in the presence of oxygen, which ultimately results in cell death. Photodynamic therapy is primarily used for the clinical treatment of various oncological disorders. It was not until the 1970s that PDT was first used clinically…
- Describe and explain the difference in results if the serial dilution step of the T4 bacteriophage suspension inour experiment was skipped (i.e., all of Step #3 of the procedures was skipped)? _________________________Current EventsThe Johnson and Johnson COVID-19 vaccine consists of inactivated adenovirus that has been altered to containgenetic information encoding SARS-CoV-2 surface spike proteins. The virus targets and delivers this geneticinformation to the cells of our respiratory tract, which produce benign SARS-CoV-2 surface spike proteins butare effective for training our immune system to defend us against SARS-CoV-2.Based on this information and your knowledge of viruses in general, could T4 bacteriophage be used in place ofQuestions 14-16 are based on the following. In the 1940's, Avery, Macleod, and McCarty transformed nonencapsulated bacteria into encapsulated. forms by growing the nonencapsulated cells in a culture containing an extract made from dead encapsulated cells. The transformed cells produced colonies of encapsulated bacteria. Three different procedures and their results are outlined below. Procedure I: Extract made from dead encapsulated cells added to culture medium. Nonencapsulated bacteria added to culture medium. Results: Both nonencapsulated and encapsulated bacteria grow. Procedure II: Extract made from dead encapsulated cells treated with protein-degrading enzymes before adding extract to culture medium. Nonencapsulated bacteria added to culture medium. Results: Both nonencapsulated and encapsulated bacteria grow. Procedure III: Extract made from dead encapsulated cells treated with DNAse (an enzyme that selectively destroys DNA) before adding extract to culture medium.…Lab 2 MicrosCO X Copy of Lab 2 X M Inbox (53,887) x b Answered: 4. 1 x C Search Textbo X + /d/1lq1XGTjeDOK-AZLP5NCDYYPZT3K6_fPLnwx-GvHgLnU/edit# Normal text Arial 12 %00 L 1 2 3. 4. 5. 9. Observing Bacteria in Colonies In fresh or saltwater habitats, cyanobacteria will appear (without a microscope) as very small green lines (as can be seen in this video). Observe the following images of cyanobacteria colonies under 100x and 400x magnification with a light microscope: Anabaena sp. 100x magnification Anabaena sp. 400x magnification As you can see, cyanobacteria grow as two different types of cells: those that are photosynthetic (fixing carbon dioxide to make sugars), and heterocysts (that fix nitrogen to make proteins and nucleic acids). Although these cells are genetically identical, each is able to accomplish this via differences in gene expression, a key concept in biology you will continue exploring this quarter. In the 400x magnification image, you should be able to clearly see two…
