hi, can I please get help on a case study on nueroanatomy I have been struggling for a couple of hours now and can't seem to understand the study to answer the following questions. is there any way or format that i can get help. I would really appreciate it. thanks! 1. Based on the information in the case, what is the most likely neuroanatomic location for a single lesion that can explain all of the patient’s symptoms and signs? In your own words, explain how you arrived at that localization. 2.What are some possibilities for the nature of the lesion (e.g., stroke, tumor, trauma, etc.)? In your own words, explain your rationale for these options. 3. How does the laboratory data and neuroimaging demonstrate the actual lesion for the patient? Describe how you interpret the data in your own words. 4.How was the patient was treated, and how did they subsequently fare? Describe the treatment plan in your own words.
Invasiveness occurs in tumours when they are looking to spread through the tissue of origin or to a distant site of metastasis. This process is often triggered or maintained by the tumour microenvironment. Critically discuss what the tumour microenvironment is and how it is proposed to aid in tumour migration.
5) The immunoblot shows probing of samples taken from a time course after treatment with the proteasome inhibitor MG132. Recall that the proteasome is responsible for selectively degrading only those proteins that have been tagged with ubiquitin. The left indicates the antibody that is used to detect protein for each panel. P53 P27 AGR2 GAPDH MG132 (h) 0 0.5 1 2 4 8 12 24 Image from Wang et al., (2019) Oncogene 38:3458-3474. a) What effect does MG132 have on each protein? What does this tell you about each of these proteins? ● P53 P27 AGR2 GAPDH b) How do we know that the differences we observe in the proteins is not due to un- equal loading of samples into each lane of the gel?
2. https://doi.org/10.1186/s12868-022-00692-1 (link to research) a) In the immunohistochemistry section of the materials and methods section the authors wrote “The number of positive cells in hotspot areas in ten high power fields (HPFs) in areas of demyelination and plaques in the brain stem were counted using the image analysis software (Lecia Application Suite Version 4.12.0, Welzlar, Germany).” Why were they looking at demyelination areas for this study? b) In the effect of mitoxantrone on histopathological changes in the brain section of the results section the authors wrote “Active plaques revealed inflammatory cellular infiltrates with abundant macrophages stuffed with myelin debris, an evidence of ongoing myelin breakdown.” What does macrophages stuffed with myelin debris have to do with the study?
There are 2 main ways of treating tumours - external irradiation by radiotherapy and internal radiopharmaceuticals. Using the points shown below, describe each process and compare and explain the advantages and disadvantages of using radiopharmaceuticals as opposed to external irradiation. An example of a specific condition can be used to illustrate the points. area of treatment required position of tumour ionising range precautions needed after treatment
