Summary of Research Article
Molecular motors are often utilised during the process of transportation of DNA through the use of ATP . This specific research article uses the process of sporulation in Bacillus subtilis to look into how a large amount of a chromosome is transported by the protein, SpoIIIE ATPase, for separation during cell division. Sister chromosomes are used in the experiment and remodelled and the site of division, the septum, is relocated to produce a mother cell, which contains three-quarters of the chromosome, and the forespore, which contains the other quarter of the chromosome. FtsZ How the SpoIIIE assembles itself around the mother cell and forespore, whilst fuelling itself via ATP hydrolysis FtsZwas then studied.
It was found that SpoIIIE were directed towards the septum even before the cell division began. This was discovered through the use of super resolution microscopy. Photo-activated localization microscopy was used to study the location and movement of SpoIIIE. Structured illumination microscopy was then used to form 3D images of the reassembled SpoIIIE, and fluorescence fluctuation microscopy was used to obtain images of the chromosomal DNA.
Eosinophils migrating to different tissues in the body are part of its function. Eosinophils that are part of the circulatory system remain inactive until they reach the tissue. The article looks at what occurs in terms of the surface markers and release of leukotriene C4 when eosinophils reach these endothelial cells. It was found that when eosinophils migrated to the endothelial cell, interleukin (IL)-4 or IL-Beta would encourage further migration. The rate of this process further increased if a chemoattractant was used. In the culture, the endothelial cells that were treated to prevent this chemotactic event would lead to a decrease in the expression of CD68. CD69 is an early marker and CD35 is a receptor. Both of these are controlled by endothelial cells and thus their expression increased when the eosinophils migrated to the endothelial cells.

Eosinophils can often be seen during allergic reactions and in parasitic diseases . This can be investigated by looking at granules granule proteins of eosinophils. During parasitic infection, the granules such as eosinophil peroxides (EPO) and major basic protein-1 (MBP-1) eosinophil-derived neurotoxin and eosinophil catatonic protein can deposit its contents onto the helminth to kill it . Thus the article looks at the presence or absence of these proteins to see its effects on parasitic disease.The article looks at the parasite Brugia malayi microfilariae for the investigation. It was found that eosinophils were needed for eliminating the microfilariae during primary infection as its absence would allow for the microfilariae to survive in the body for a longer period of time . The absence of EPO lead to the increase in levels of Immunoglobin E (IgE) which meant that eosinophils have a role in the controlling the levels of IgE . The article also states that eosinophils can have both a positive and negative effect as the removal of MBP-1 lead to increased mucus production by goblet cells but the physiology of the respiratory system did not change with its absence .

Eosinophils are a type of leukocyte that has many functions in terms of inflammatory response: has a role in parasitic, bacterial and viral infection, allergies, tumours and injuries to tissues. Therefore, maintaining a certain level of eosinophils via activation and programmed cell death is important for the immune system, as eosinophils can regulate antigens, tissues, as they can also encourage the inflammatory process via release of cytokines and lipid mediators. This article further studies the regulation activation and apoptosis of eosinophils via the influence of Natural Killer (NK) cells. In humans, eosinophil activation can be influenced by the increase in the CD69 protein activity and the decrease in CD62L activity. On the other hand, eosinophil apoptosis can also be influenced by NK which could be seen as the rate of apoptosis was higher in the culture that was incubated with NK cells.

Eosinophils are created from the eosinophil lineage committed progenitors (EoP), CD34+ cells , . They get produced in response to infections and diseases that cause an inflammatory responses which leads to an increase in amount of eosinophils present in the blood due to cytokine interleukin 5 (IL-5) , . EoPs develop into its mature form via the influence of the regulatory molecules that control IL-5 , , . The alteration of IL-5 levels affects the rate at which EoPs can mature but does not effect the ability of the bone marrow to produce CD34+ .

The first thing I noticed was that the way that the assignment was structured was very logical. It progresses from the most broadest topic to the more detailed topics. It also follows a good chronological order as it addresses the history of megakaryocytes earlier on in the project and then goes onto how they develop and mature. This is good for students who are unfamiliar with the topic as it makes it easier to absorb information. One of the things I would however suggest to add is a picture in the structure section. When learning about structures of things, it is often easier to visualise or interpret the information if there is a picture as reading all the descriptions of the different structures can be a bit overwhelming. I also noticed that there were sections without referencing throughout the project, especially in the Introduction, Thrombopoietin receptor, Maintenance of Haematopoietic Stem Cells in the Quiescent State and Essential Thrombocytosis sections. Basically, every time a statement is made, it should be followed up with a reference. Other than those small issues, it seems like the assignment is heading in a good direction.
With this groups' assignment I noticed that they also had a very good structure. Things were written in a logical order that built up the readers knowledge of the basics on red blood cells before going more and more in depth. One thing that I did notice however, while reading the assignment was that, in the sections with diagrams/pictures the paragraphs did not seem so hard to read. Under each heading is quite a large portion of writing. Having no bullet points or tables makes it quite difficult to read for a university student who is being newly introduced to the topic. It is not that the information is difficult to absorb, but more that it makes the reader lose concentration, especially the Diseases and Abnormalities section. If there were more pictures or as mention bullet points/tables to simplify the large paragraphs that were written, I think that would make the assignment seem more interesting.
This group also had a good structure. Starting from the introduction, which gives a good overview on lymphocyte B-cells, going on to structure, function and then it's role in disease. The information written by this group is easy to read and simple but in depth enough for a third year medical science student. Although the information was found and written was good, this group also wrote in large paragraphs which tends to cause students to lose interest. Having a more visual approach could be a good option. Pairing the information with more images and utilising bullet points and table to summarise instead of lengthy paragraphs could possibly make the project seem more interesting. Another problem I noticed was this this group did not include any in-text citations at all! They did however have the references at the end. It is important to add an in-text citation with every statement to indicate which information came from where.
Just like all the other groups, the first thing I noticed about this groups' project is that it followed a good structure. It started with the most broadest information in the introduction section and then led to more in-depth information in the sections about disease and current research (the inverted triangle technique). It was great that this group included a photo in the section about the structure of Natural Killer Cells (NKC). This was very helpful as that section is essentially trying to allow the reader to form an image of what NKCs look like. Surprisingly not all the groups did this so that was good. On the other hand, the images with the caption "Receptors of Natural Killer Cell" and "Natural Killer Cell effector function" were so small you could not see the diagrams on those images clearly. In that case it would be better not to use those photos at all. Try to download large images so that you can expand them/shrink them to your preferred size. Also, to me personally, I thought the Rheumatoid Arthritis portion under the heading "Abnormalities in Disease" was abnormally long. This could mean that the reader could lose interest. The information was good however it was just a little overwhelming. The group however did make up for this issue by including a table! This table was to summarise the diseases. This was a great idea!
Out of all the projects, I think this groups one was one of the best ones. It had a good structure and flow. It started with the introduction and gave more descriptive information as it got to the sections on. The information they wrote was paired with images or tables that supplemented the information that was written. There were sections of the project where it did seem like the information was almost too lengthy but the tables that were created allowed the reader to absorb the information easily. If you did not understand the paragraphs, you could refer to the paragraphs. The only thing I could suggest for this group is to possibly use some bullet points in the other paragraphs that are quite lengthy but do not have a table for image to support it.
By reading this groups' project, you can easily see how much effort they put into their work. This can be seen from the amount of information they have gathered through research. This is great but the amount of information provided is definitely overwhelming for someone who is new to the topic of T Lymphocytes. In each section of the project, so much time and effort has been put in which is great! I think it would however be easier to read if the group could use bullet points or more tables. It is very difficult to absorb large amounts of information at once, especially if they are written in a paragraph format. The group did couple images with the lengthy sub-sections which was helpful in terms of absorbing information. As mentioned before, I think adding bullet points as well as tables along with the images would be good if the group was planning to keep all the information they have written.
