Medical Physiology student... woohay!
soo the MB1005 exam is problem-based. There are only tutorial and past exam paper to learn from. What about the lecture content, how much should we know from it? Everyone is saying just understand it, but there is a difference between understanding it and being able to real off every detail of topics for an exam.
Not sure how to approach revision of the lectures :( - Rebecca Zammit
I am finding the MB1004 podcasts useful for going over topics :D
I love that we have the option of listening to the podcasts, so useful! - laura miller
How can the gain of the stretch reflex be modified?
Does anyone know how many microorganisms we need to learn from the microbial biotechnology lecture(there are so many examples given!!)? ( i think its the last ever lecture of #BS1009)
not a clue but i wil try to get a few down just to get extra marks! :) - Harriet Giramahoro
yeaa better safe than sorry. oh dear, i just don't know how they are going to stick in my head :( good luck everyone tho for Tuesday :D - Rebecca Zammit
is there a mock paper for #MB1005?? i have only found answers and I am not even sure if that is just for the BS people. thanks :)
"linking functional declineof telomeres, mitrochondria and stem cells during aging. ". Constructing a model of how telomeres, stem cells and mitochondria interact with key molecules governing genome integrity, 'stemness' and metabolism provides a framework for how diverse factors contribute to ageing and age-related disorders. This is very interesting and the subject of telomeres is familiar to me as we discussed it last year for the biochemistry module. - Rebecca Zammit
The title of this article is called: "The genetics of ageing."With age, protein homeostasis declines and damage accumulates. Thus, it seems self-evident that ageing is caused by macromolecular damage, and a show of hands at a recent ageing meeting confirmed that most people working in the field believe this. - Rebecca Zammit
The title of this article is: "Meet X-woman: a possible new species of human" It describes how DNA collected from a fossilised finger bone from Siberia shows it belonged to a mysterious ancient hominid – perhaps a new species. It is seen to be the beginning of a new way of understanding human history. Sharon Yim also linked to an article about this discovery. - Rebecca Zammit
Revision plan
Instead of laying out an ellaborate and ambitious plan for every single day of the easter break, I will be more realisitic with my revision timetable. I aim to follow goals for every week so that I will be motivated to finish a topic and move onto the next target. Then i aim to have some time before the start of term when I have completed all my overall revision of topics so that I can generally work on consolidating all my knowledge by putting up posters or revision cards for all the topics. - Rebecca Zammit
This is an interesting article titled : "Mind over matter? How your body does your thinking " - Rebecca Zammit
It looks at how body acts over mind. It assess whether different bodies causes us to have different is interesting because the article looks at different brain activity between those who are right or left handed as an example. - Rebecca Zammit
After the friendfeed assessment I think I will still use friendfeed because it has been an encouraging source of information, discussion and expression of ideas. I would be grateful for the continued contribution from lecturers on friendfeed because it is an easy way to post queries and recieve answers. - Rebecca Zammit
100% agr - Helen Nigussie
Yep, I initially thought that friendfeed was pointless but now I'm converted. It's a really good resource for finding information. - Rajeeve Parmar
yess, i just hope that not only the teachers but students keep asking and responding to queries/posts on friendfeed. - Rebecca Zammit
We'll still be here @rebecca! - Dr Jo Badge
Ive really enjoyed using friendfeed aswell, and i think its a helpful way to talk about work with other students on our course - ameera laher
I'm going to have to agree with the majority. Friendfeed has been a very useful method for imparting and retreiving information amongst my peers. I will probably continue to use this site in the future. - Mohammad Hamdan
Friendfeed as been quite useful. The only question I have is that would everyone have contributed as much to it had it not been weighted so heavily for the #BS1011 assessment? - Ashton Chugh
friend feed realy helps - Johana Dhokwane
The title for this interesting article is " 'Junk' DNA gets credit for making us who we are " Recently in lectures we have come across junk DNA but have been told that many are unsure about its role in the body. So, this article includes information about scientists discovering that non-coding DNA which makes up 98% of our genome is responsible for how much of a protein is made and determines whether a gene is turned on or off. - Rebecca Zammit
I thought this article was quite interesting, it was diffiult to follow at times - ameera laher
Haha, I posted this article before even reading your post. Now I've read yours and I feel a bit silly lol =]. Interesting article non the less. - Mohammad Hamdan
It is amazing how medicine has progressed over the years i.e. from treating the 4 humours to looking at molecular and genetic of the patient. - Kashif Qamar
True Kash. I've actually read a fantastic book called 'A Brief History of Medicine' which basically tells the story of medicine, from Hippocrates to modern day. - Mohammad Hamdan
I did 'Medicine throughout time' in GCSE history .... it just makes you appreciate science even more ! - Kashif Qamar
It does. I alot of people sacrificed for what we take for granted in modern day medicine. - Mohammad Hamdan
This article is called: "Control of sexual differentiation and behavior by the doublesex gene in Drosophila melanogaster" This article is about the double sex protein that is involved in the sex determination trhoughout the animal kingdom. Scientists in this experiment inserted a gene called Gal4 into the doublesex (dsx) locus of Drosophila melanogaster, so that they could visualize and manipulate cells expressing dsx in various tissues. They found that dsx was required for the development of male-specific neurons that coexpressed fruitless (fru), a regulator of male sexual behavior. They proved this by observing changes in male sexual behavious as soon as the neuronal function of dsx was distrupted. This topic was covered in a really interesting lecture as part of the #MB1031 module about genes and behaviour. Changing the sexual orientation of Drosophila melanogaster was also mentioned in the lecture that relates to this article. - Rebecca Zammit
Again, the last 5 posts where from yesterday but internet connection issues prevented me from sending them. So, they should be considered as last weeks posts. - Rebecca Zammit
This is another article about antibiotic resistance which interests me because it has become such a problem for the health world at the moment. It is something widely researched because otherwise it would make the discovery of antibiotics which was one of the most important medical breakthroughs, redundant. The article is called: " Antibiotic resistance and its cost: is it possible to reverse resistance?" It comes to the conclusion that the study of bacterial fitness is important to assessing their ability to become resistance to antibiotics as low bacterial fitness leads generally to resistance. It covers the possibility that resistance could be reversed but this development will be slow. - Rebecca Zammit
Antimicrobials: Reactive resistance is the title for this article. It is relevant to the #BS1009 module as antibiotics and resistance has been discussed. This article includes information about bacteria that have a low concentrations of bacterial antiobiotics within their system are able to generate resistance to whole range of other antibiotic by forming highly toxic hydroxyl radicals, which can damage DNA, proteins and lipids. This may lead the way for the emergence of multidrug resistance. - Rebecca Zammit
This article is called : "Firing on all neurons: where consciousness comes from". It is about consciousness which looks at the mental and physical recovery of a 20 year old who suffered a stroke which started to show that conscious could basically mean the coordination of neural activity. Scientists now suggest that parts of the brain (such as the visual cortex) process non-conscious experiences, whilst conscious experience occurs when this information from parts of the brain are broadcast to an assembly of neurons that cover many different regions of the brain called a "global workspace". They have shown that the brain actively selects what information is sent to our consciousness. - Rebecca Zammit
Also, I would like to add that I had my internet connection stopped half way through researching topics that I am covering at the moment on friendfeed. So I am posting links that I couldn't send last week so should be seen as posts for last week. - Rebecca Zammit
This is a link to a site that allows access to all sorts of science related journals. Personally, I have been running out of useful sites to use for research and I preferably like to use lots of different sources because I feel it positively influences your work by allowing you to look at a subject more broadly. So, I am currently looking for new sites with more journals. If ony we had access to nature and new scientist for free on the internet :( - Rebecca Zammit
You do have free access to both of those publications :-) check the elink access on the library web pages. If you are off campus use - Dr Jo Badge from iPod
Really??? i have tried everytime in uni and outof uni and it never works. I will try again. - Rebecca Zammit
This is really useful; I always find it hard to find scientific journals to look at that are appropriate to what I'm studying. It's not always easy to know how much further reading we all need to do. - Matthew Helliwell
Super useful! - Anthea "Red" Mutepfa
going to be useful for me too :D - Freya Satchell
Here is an article from Neitz et al. It provides useful background information for the genetics report that must be written by 25th March for the MB1031 module. The report is about determining wheher two closely related genes for red and green colour pigmentation encode for one pigment or the other. - Rebecca Zammit
I signed onto "Remember the Milk" to put up my to do lists and motivate me more to complete tasks because its nice to see the message pop up when you complete a task!! he he, It also is harder to lose your to do list on Remeber the Milk in comparision to physical to do lists on paper!!!
This is compares the cardiovascular and other effects and uses of adrenaline and noradrenaline. The main difference is that noradrenaline stimulates alpha 1 ,2 and beta 1 receptors whilst adrenaline stimulates alpha 1, beta1 and beta2 receptors. - Rebecca Zammit
However, I am not sure if this site is correct because I remember being told in lectures that noradrenaline and adrenaline have the same functions and adrenaline is the breakdown product of noradrenaline so i am not sure if it is true that they bind to different receptors. This is why friendfeed comes in handy, hopefully someone can clarify? - Rebecca Zammit
Oh nooo! its wiki! :O However, this site provides a useful basis for the lecture we just had on the autonomic nervous system. It includes a useful table to look over because it shows the mechanisms and effects of different receptors. For example noradrenaline can act as an agonist that binds to the alpha1 receptors and cause smooth muscle contraction. - Rebecca Zammit
This article discusses whether bacteria in our body controls our behaviour. It looks at an example of mice that have been genetically engineered to be TLR5 deficent (which is a protein) that can reconise bacteria. These mice were 20% times fatter than mice who had the protein and suffered chronic inflammation because they felt more hunger so ate more all due to the changed microbial make-up of their gut. - Rebecca Zammit
This article shows how scientists are trying to find new ways to beat the growing problem of antibiotic resistance. This article mentions how scientists have unraveled the structural basis of the terminal step in bacterial isoprene synthesis which is important because it could lead to custom made antibiotics. So they can stop pathogens from finding alternative pathways to making essential compounds which causes antibiotic resistance because antibiotics works by stopping this compound formation. - Rebecca Zammit
This link is titled : " Can corn be taught to fix its own nitrogen?" This is interesting as I had researched the role of microorganisms in the nitrogen cycle and nitrogen fixation. This article mentions how scientists are working towards adjusting corn crop so that nitrogen fixing bacteria could communicate with the root systems of corn plants. This would mean that money could be saved because nitrogen fertiliser applications wouldn't be needed anymore. - Rebecca Zammit
I found this site very useful for understanding crossbridging. It includes a background to how muscle contraction was explained bichemically and clearly explains the use of ATP to disconnect myosin from actin and myosin hydrolyses ATP for the release of energy that causes muscle contraction. - Rebecca Zammit
I used to get really confused with this stuff when we only half covered it at A level. Makes much more sense now - David Laithwaite
is just wandering whether a set of data can have normal distribution even when the mean mode and median are not exactly equal or if the histogram doesnt exactly show that it is normal distribution or does it have to be perfect?
How do I like to be taught?
I find some lecturers methods of teaching very beneficial. For example, we had a physiology lecture today and I found that Dr Mitcheson mentions the main points but takes care to repeat the important parts. I find this useful for me because it can seem like a constant battle to write what the lecturer is saying and keep up with flow of the slides and content. So not only does repetition of the main points throughout the lecture reaffirm our understanding but allows us also to record it in our notes and be used for revision. I also feel that I learn more when a concept is explained in more than one way because this makes it easier to understand. - Rebecca Zammit
I also find it makes such a difference when the bullet points on the slides are set out in a way which highlights the main points. It means i can concentrate on what the lecturer is saying rather than trying to work out how to lay everything out on the page (which I find is important when coming to look over notes. - David Laithwaite
I agree, a clear concise powerpoint layout makes it easier for us to understand is useful for note taking for when the all important revision period comes along!! - Rebecca Zammit
Lots of academics think that Powerpoint is the worst thing that ever happened to teaching - makes students too dependent and less independent. PowerPoint was invented for business use - to sell things. Not well suited to deep thought? - Dr Alan Cann
I see where they are coming from. So, why do so many infact all of our lecturers use and depend on Powerpoint? I find them useful because we can use them to know the main topics that we need to understand and to look up. But yes completely relying on lecturers Powerpoints is not a good idea because we need to enhance our own independent learning. - Rebecca Zammit
yh i agree zammit!! not only that.. i like the way he write on the overhead because he is clearly outlining an important point and by taking us through it step by step we can really get to grips with the concept! good times!! I really enjoyed those three lectures..may be because we had already done most of it and the re -iteration was beneficial and easier to follow! - Neel
Yea.. i think it is because u have done it already that it makes sense! but i get really ignored in that lecture because there is no outline wat he is goin to do! it frustrating because some of the things he writes on the overhead are important processes that should have been on the powerpoint but every lecturer is different so i guess i hav to deal wit it! - Harriet Giramahoro
Yes I can see how this would be annoying. But for me personally, it keeps me more alive in the lectures because I know that I can't just fall back on the lecture slides all the time because there isn't everything that the lecturer is saying on them. So I am more inclined to listen and take notes and therefore learn the information quicker. He also makes sure he goes through things... more... - Rebecca Zammit
My SMART targets.
1.To complete practical work within 3 days and check with staff and students questions that I am having trouble with. - Rebecca Zammit
2. I intend to organise my file properly this weekend and aim to have used books to make notes on every lecture by the end of this term. In the meantime, I intend to read over previous and present lecture notes before lectures so that I can be prepared for them. - Rebecca Zammit
3. Also, I intend to sort out work to do in the summer including volunteering products by the end of this term and start organising my research for it in the next two weeks. - Rebecca Zammit
Does the word count for the microbiology essay #BS1009 include figure legends?
i think not... - Andria Pelava
Usually it shouldn't. :) - kemisola
The same site provides useful imformation about how to design scientific posters and reports if you follow the links. The lecture on how to make an effective poster was useful because it helped me get an idea on what things to focus on. This sites is a good reminder of what to keep in mind when attemping to design the poster for #MB1031. - Rebecca Zammit
