The University of Southampton

Introduction

The concepts and assessment methods in this module are very different from my degree course which is Physics. Last semester I studied nano-physics this really interested me. I thought it would be interesting to get the chance to explore other disciplines than pure physics as many of the limitations of nano and micro physics are only apparent when looking through the lens of another subject, like many imaging techniques being destructive due to high energies required or needing thin or conducting substrates or very low temperatures due to thermal noise.

Engineering Replacement Body Parts

Hello, my name is Evan Masters, I’m 19 years old and am in my second year of Biomedical science. In what little spare time I have I enjoy running, gaming, gym and procrastinating. In terms of societies, I’m a bit lazy, though I do play esports for Southampton University and am playing in the qualifiers for a £10000 tournament tonight (02/02/2023), so wish me luck.

Why did I choose this module? First and foremost, this actually looks fun and interesting, especially when my other option was Protein Structure and Function. This also is mostly assessed by coursework which really helps with the stress of exam period. I also might be able to understand some amount of the module, unlike Protein Structure and Function, I really didn’t want to do that module.

I find stem cell research really interesting, initially I was going to do an integrated masters with placement in Scotland in stem cell Embryonics, but alas I did not have a chemistry A level which was required. My brother is also missing a lung so growing him a new one would give me irreputable leverage over him and strengthening my position as favourite child.

Other than that, I tend to enjoy learning outside my field so doing an interdisciplinary module, especially one involving engineering aspects, should be an enjoyable time :).

Introduction

I’m Florrie, I am an exchange student from New Zealand. My university in NZ is called Victoria University of Wellington. I am doing a whole year here in Southampton. I study Biomedical Science and am in my final year. Although I live in NZ I am originally from the UK, I moved to NZ when I was 5 years old. I have also lived in Sydney, Australia. I live in Wellington, which is the capital city. New Zealand is a beautiful country, it has a similar land mass to UK but only has a population of 5 million. One of the coolest things about New Zealand is that we have serval active volcanoes. I have attached a video below of things to do in New Zealand.

The topic I am most excited about in this module is stem cells and research ethics. I am looking forward to learning about how stem cells can be used to help cure diseases and aid in medicine. It will be interesting to learn about how ethics affect the work that can be done and how they are used in regulating research. I have done some lab work with Henrietta lacks cells back at my uni at home which was really interesting seeing how they develop depending on what chemical they are exposed to. It was also comparing the growth of cancerous stem cells to normal ones.

Lego- building blocks for life?

This is David Aguilar, he was born with Poland Syndrome which is a condition that affects the chest muscles, causing them to under develop at birth. Blockage of blood vessels in the womb can lead to this and other conditions such as Brachydactyly.

David had an interest as a child for Lego which lead to his development of his prosthetic arm. He used Lego Technic to create his model the ‘MK-1’ (iron man reference) which involved motors and his adaptation of fine motor movement with fingers and pressure sensors.

David is still evolving his prosthesis and creating new updated models using cables to contract to simulate muscle contraction. There is a book, documentary and many more articles about Davids story, including his youtube ‘Hand Solo’.

This video explains more about Davids story from himself

As a Lego employee myself it is amazing to see the extent to which Lego can go and not only be a bit of fun for kids. It is amazing how life changing it really is and the possibilities there are with it.

I believe Lego technic could be explored more in the world of prosthesis not only for function but to help introduce the topics to children to allow them to explore the world of STEM and possibly aid children who have conditions where prosthesis are an option, Lego may make this seem less daunting and allow them to explore this whilst having fun.

Why am I taking Engineering Replacement Body Parts?

I do natural sciences, and this is a compulsory module in the third year. At first I was a bit confused why I had to do this module, since it doesn’t have a lot to do with what I usually study. In fact, up until a couple of months ago I thought the compulsory module would be ‘Life in the Cosmos’ which I was really excited to do. However, after attending the introductionary lecture, I am beginning to appreciate that this module will draw from a variety of disciplines and will give me insights into other subjects. I am particularly interested in the ethics lectures since this is not something that I have studied before.

In Natural Sciences I am free to choose modules from a variety of courses- for me that’s mainly biology and marine biology. Right now I am doing a project looking at the protein prophenoloxidase in crustaceans, which is part of their immune system.

One type of replacement body part that I have seen in practice is lens replacement surgery which my mum had a few years ago to treat cataracts. It was really cool to watch how someone who had relied heavily on glasses and contact lenses for over forty years suddenly be able to have the freedom to be able to see clearly without anything. Even something as simple as washing her face without having to worry about getting her contact lens wet has made a huge difference to her life.

My name is Yifan, and the course I take is Business Management. There are two main reason for my choice of this module. First, limb prosthetic interests me the most from all the biology aspects of the module. Mainly deriving from the fictional works of all types I was exposed to. Moreover, thinking of the benefits of a limb prosthetic that is able to mimic the full functions of a real limb is beyond my imagination. The type of pain of a person’s daily life brought by accidents or genetic issues is imaginable. So if a seamless technology become available to offer to those in need, it would bring the world a ton more joy. Secondly, the ethical theory application to the module interested me as well. This is mainly because of the ethics module undertaken last semester. It would be interesting to make that connection and see how different theories debate with each other when applied to different situations. For example, if I am correct about the main content of the ethical part of this module, which is about consent, this can be applied to many ethical theories such as Kantian’s and JS Mill’s. Also, it would be interesting to see how some of the practices can be justified or condemned based on deontology and utilitarianism views.

lol hi

dont rlly know what to write…anyways I’m so tired right now. Karaoke was fun last night WOOOOO!

why did i pick this module? probs coz its 40% exam lol (sike it actually sounds cool)

my hobbies are gaming, art, dance (street dance) and volleyball. basically any sport sounds fun i guess. LOVE mgmt and their music…low-key getting into nirvana at the moment.

my guy got a fresh trim.
LMAOOOOO

‘comonmuvyabadi’

slay

i am writing this hungover how am i supposed to live laugh love in these conditions

cafe parfait is kinda mid ngl

anyway, this module seemed interesting, which is why i picked it! i do biomed and this seemed like a really interesting extension of the content i’m currently learning

did you guys know there’s a protein named after sonic the hedgehog? that’s pretty cool

the sonic hedgehog protein is a signalling molecule that helps regulate embryonic morphogenesis in all animals

a bit about me: i like tennis, reading and music, mostly indie. i’m currently trying to listen to all of radiohead’s discography in chronological order; i’m up to a moon shaped pool

cheese.

i’m realising this post is just non sequitur after non sequitur i’m sorry lmao

Example/Test 2

Targeted drug delivery has always been a keen interest of mine. Having seen first hand the effect of chemicals such as chemotherapy drug being delivered to the whole body rather than just the tumour, I am excited by the possibility of being able to prevent these drugs from affecting healthy tissue. Microbubbles have been used widely in targeted drug delivery and contrast imaging. However, their relative instability is a key disadvantage. Enter the nanodroplet: a particle of diameter ~200nm with a perfluorocarbon core and phospholipid shell. The smaller size allows them to be more stable and less likely to be removed by the immune system.

Structure of a nanodroplet


It has been shown that the superheated stability of nanodroplets enables them to undergo acoustic droplet vaporisation (ADV) to become a microbubble. ADV occurs due to an applied ultrasonic sound wave. Sound waves occur due to changes in pressure in the surrounding media. Areas of increased pressure occur as a result of the particles being compressed together. Areas of decreased pressure occur due to the particles spreading further apart in a phenomenon known as rarefaction. Rarefaction results in a decrease in pressure in the nanodroplet. If the pressure drop is enough then the required vaporisation temperature will reduce to the surrounding temperature allowing the nanodroplet to vaporise into a microbubble of diameter roughly 2.5-3.5 times the diameter of the original nanodroplet. If the peak negative pressure is large enough, the resulting microbubble is able to undergo inertial cavitation where the microbubble diameter doubles then violently collapses due to the inertia of the surrounding fluid which increases delivery of gases dissolved in the encapsulated perfluorocarbon by either increasing “leakage” from the microbubble or increasing permeability though the endothelium.

Diagram demonstrating what is meant by rarefaction

Overall, I feel nanodroplets are a promising new technology in the field of targeted drug delivery. They have the unique ability to solve the challenges posed by current microbubble therapy without completely redesigning the wheel.
