week 10- critique of project pages
I have found this process to be enlightening and beneficial. The standard of the pages is very good in general. The pages use very good evidence and are quite readable. Much of what i have learnt has also been useful to other subjects!
group 1: Megakaryocytes (MK)
The page is good, but the main problem is a consistent misuse or no use of proper referencing. Here are my observations:
- Unreferenced statements thrombopoetin section
- ET references box is not technically referred to so it’s a bibliography not a reference
- Glossary is unfinished
- History is fully unreferenced
- “Megakaryocytes have been shown to maintain HSC quiescence during homeostasis “ i think this would read better if it was written "in homeostatic conditions"
- I like the figures but they have very little text information. Figure 4 could discuss in more detail the 4 branches of the mind map of MK functions.
- Good job inserting the essential thrombocytosis video but I would put it under the Essential thrombocyte title not the “pathology” title seeing as it’s specific to one pathology.
- For consistency I would ensure that all acronyms are uppercase (in CAMT subsection of pathology some acronyms aren’t in uppercase. Also you use the acronym TPO several times and describe it several times. You could reduce the wordiness by just doing this once.
- Needs a reread through for minor spelling checks as well.
group 2: Red Blood Cells
great history and function sections. a couple of issues however in the whole page:
- Under the structure section, the first sentenced is referenced with “Dinkla et al.”. This should be made a footnote and have date attached. Remember it doesn’t have to be a pubmed affiliated article to be made a footnote just put in “”
- Under membrane composition, it seems you’ve tried to encorporate a subsection “defgormity /fluidity. This looks tacky with just a dash. I suggest making it bold. Just add 3 apotrophes before and after.
i.e. if I want the word “bold” to be bold, I would write ‘’’ bold ’’’.
- I would have wanted to read much more about ABO blood grouping, there isn’t much there, you should also incorporate pictures here. This could be a whole section!
- Another seriously important factor of RBCs is that they have a Fc receptor and can carry immune complexes to spleen or liver. The immune function of RBCs is not really touched on, and that’s a major issue.
group 3: B cell lymphocytes
A lot of good quality information but a very bland page. Here are some notes:
- History is not very extensive
- B-cell development and B cell subset image is very small! I would make it twice as large (800px). And maybe describe it in text more
- Section: development, 3rd paragraph: spelling error
- Instead of using in text referencing, you should use footnotes (easier for the reader to find the references). Remember it doesn’t have to be a pubmed affiliated article to be made a footnote, just put in “”
- Section: development. You introduce the term L chains with no description, the reader may have no idea what that is. Make sure you describe newly introduced terms!
- There is an underwhelming amount of images used. Images should be used for:
o B cell activation o Mind map of different B cells o Different antibodies
- Tables are bland as well, try adding some colour!
- Evidently you must finish the immunodeficiency/ and b cell cancer sections!
- Also go into more depth about the biotechnology applications of B cells and don’t forget references!
group 4 Natural Killer Cells
Looks pretty good, but many sections unfinished, here are soem notes:
- History is not extensive
- Receptor image must be made larger
- Receptor section is unfinished
- In structure section, the 3 ways that NK identification can be grouped could be bolded. This would make it more distinct.
- Some claims are not referenced, i.e.: Recent studies speculate that NK cells also play a role in regulation of dendritic cells, macrophages, T cells and endothelial cells
o You cannot tell the reader what recent studies speculate then not reference which you are referring to.
- Rheumatoid section is 90% unreferenced. A footnote is meant to be used at the end of each piece of information that was used from that source. Theres only one footnote used in the 8 paragraphs.
- Diabetes and lupus sections are unfinished.
- The current research section has good content, but doesn’t flow well. And needs to be reread for several small errors, (i.e. there is a random “-“ symbol half way through 2nd paragraph and some of the sentences could be restructured to read better.
- No glossary
Group 6 T cell
Very extensive, Very colourful, Very informative. The main theme of criticism is in the language used, but the content is great.
Many sentences have good information but need to be reread and rewritten to make sense. A classic example is : A plethora of subtypes and difficulties to find adequate markers have provided difficulty to clearly establish what Treg distinguishes from T effector cells
Technically it makes sense but it may be rewritten to have more flow to example:
There are a plethora of difficulties in finding adequate markers to clearly distinguish Tregs from T effector cells.
- It doesn’t read well to day: as reviewed in (footnote). I would recommend using the normal authors names then foot note that. I.e. as reviewed in Robertson et al. (2000)(footnote)
- Also, you refer to the same review in two continuous sentences. Perhaps you can make the paragraph flow better by using linking language. i.e. this previously mentioned review by Robertson et al also discussed…
- I like the video
- There are some spelling errors which imply a reread is necessary. i.e. subsection function you say “makers” not “markers*” etc. Also the next sentence doesn’t read well “ To gives a mobility the physical structure of the T cell has to continuously remodeling. “ rewrite so it says “to give mobility*” Some sentences have poor grammar i.e. don’t start with a capital letter etc.
- Great job explaining VDJ recombination, I would give the images titles though. This would make it easier for the reader to have a text title to refer to. You can do this by just making the the title of the images in bold
- History isn’t very extensive compared to the standard of the rest of the report
- The sub sub table “autoimmune diseases” needs to be addressed. It’s telling the reader to go look up information! And the following HIV section only has a photo that’s much to small to read from! There are several areas that require addressing
- Interesting that Tregs are relatively non motile, did you know after appendicitis there’s a massive release of Tregs from the appendix that spread through the colon (with relatively high motility) maybe that would be an interesting add-on
- Great job on the summarising of Tregs in cancer involvement
- I love the Research at UNSW section, great original thinking.
- No glossary’
- Also when discussing the TCR it says the TCR is "simple" then proceeds to explain the paragraph that is pretty complex. Even if it's simple to the writer, when you use language like that you risk insulting the reader.
group 7 Eosinophils
colourful with short punchy paragraphs that are informative! here are some notes:'
- History is great, but only goes until 1879! Did nothing happen between then and now!
- In terms of the paragraph structure of the Birth, Life and Death in the Body section, there is the number 3 (perhaps a footnote) in the 3rd paragraph that needs to be removed or converted to a footnote. There’s also some other spelling mistakes like in MBP section you’ve spelt asthema instead of asthma. Perhaps it’s worth just rereading over the whole thing to correct the little errors.
- Add some text for the images, and I would recommend having the image title in bold.
- Video did not play in Wikipedia, but it was spectacular to watch in youtube!
- I would be interested in knowing if anytreatments are being developed specifically targetging eosinophils in eczema
- The schematic representation of eosinophil trafficking image should be enlarged. Also to add a text box below the image refer to our first lab class. This should be done with all your images
Week 4 - Super-resolution microscopy
SUMMARY: T-cells are highly mobile and have to travel relatively long distances within and outside the circulatory system whilst forming thousands of transient reactions with antigen presenting cells. Actin rearrangement is significant in the motility and extravasation of T cells. When T-cells bind to MHC to form an immunological synapse the spatio-temporal behaviour of the proteins change. For example, in the formation of micro and nano clusters.
Micro and nano clusters of proteins allow for dynamic control centers in the cell membrane. An example of these are the T cell receptors. However until now most of the information we have about these micro clusters have come from biochemical techniques but now with the advancements in super resolution microscopy, we can "see" beyond the previous diffraction limit to a resolution of 200nm.
The use of the super-resolution microscopy, in particular the single molecular localization microscope techniques, allowed researchers to get high quality data and to elucidate the 3 dimensional structures and even functions of the nano clusters, such as the TCRs and observe their behaviours temporally.
Summary: People who suffer from systemic mastocytosis have clinical manifestations that are characteristic of mast cell mediator release. A similar disorder called monoclonal mast cell activation sydrome (MCAS) has an unclarified clinical manifestation. Unlike mastocytosis the patient doesn’t have abnormally high levels of mast cells (MCs), rather, the MCs they have express chemical mediators excessively. The aim of the study was to determine the clinical manifestations of MCAS and to compare it against the recently proposed diagnostic criteria. The authors of the paper ruled out clonal MC disease and found lab data indicative of MC activation. Further, the patients responded to anti-MC therapy. This was part of the classification used in this experiment to include patients as MCAS sufferers (this criteria was pre-established by previous research). The clinical manifestations and diagnostic criteria were consistent with one another. Almost all patients had abdominal pain, dermatographism or flushing. The research suggested that MCAS should have a more significant clinical profile due to its excellent response to anti-MC mediators. There were, however, some limitations such as: it was a nonblind study and there is no consensus as to a reference standard for number of mucosal mast cells in GIT.
Summary: Poly-unsaturated fatty acids, such as some mast cell mediators, are involved in inflammation. Bronchial hyper-responsiveness (BHR) is a state of heightened sensitivity to bronchospasm that can occur as a result of mast cell mediator release in asthma and COPD. This study aimed to investigate whether dietary omega-3 PUFAs could inhibit mannitol-induced BHR. Mannitol induction of BHR mimics mast cell activation. The study was a randomize, double-blind, placebo controlled and crossover trial design. Patients suffered from asthma, did not smoke, and took omega-3s for 3 weeks. The omega 3 supplementation did not change the levels of mast cell pro-inflammatory mediator release. It is likely that it is more difficult to change the metabolic profile of mast cells than just by dietary intervention as the mast cell probably still has a significant reserve of pro-inflammatory lipids.
'Rapamycin-insensitive companion of mammalian target of rapamycin' (RICTOR) is a protein that regulates cell growth as a result of the presence nutrients and growth factors. This study showed that RICTOR can function as a negative regulator in igE induced mast cell degranulation, independent of other regulatory proteins like mTOR or mTOR2. They further showed at what stages in the molecular pathways the regulation took place. By analysing Ca2+ mobilisation and cytoskeletal rearrangement with confocal microscopy they were able to hypothesise that there was phosphorylation of certain proteins (LAT and PLCy1). They compared their results with a RICTOR knock-down model and found a decrease in igE induced degranulation
Summary: Estrogen seems to have protective effect on heart cells. It likely interacts via the receptor GPR30 which is expressed in the heart. Estrogen may even regulate components of hormone systems associated with the heart like the renin-angiotensin pathway. This study aimed to investigate whether the cardioprotective effects observed as a result of estrogen occur via GPR30. GPR30 has important regulatory roles in cardiac mast cell activity and proliferation. This experiment will be looking at the latter. The findings suggested that the effects of estrogen on cardiac mast cells/chymase/Ang II occur specifically through activation of GPR30 to decrease cardiac mast cell number. However, further investigations are needed for the exact mechanisms by which GPR30 affects cardiac mast cell number in vivo. Investigation in the mast cell GPR30/chymase/angII pathway could have therapeutic uses in postmenopausal women at risk of cardiovascular disease

What have i learnt today? (10/4/16)
This beautiful morning i have spent the past hour enjoying the tasty luxury of learning about the programming involved in the creation of wikipages. It is quite an auspicious opportunity to spend such precious time among such rich company. Attendances, links and even subheadings have been mastered in this lab.
