Going with our guts to find new treatments: faecal microbiota transplantation at Imperial

Dr Ben Mullish and Dr Julie McDonald explore the ins and outs of faecal microbiota transplants – it may sound unpleasant but this procedure is proving to be an effective way of treating chronic gut infections.

Most of us can name (or may have had first-hand experience of) a number of different bacteria that can cause serious gut infections, such as Salmonella or Campylobacter.  However, what is less well-known is that we also have billions of bacteria living in our guts that normally do us no harm at all.  Some actually have important contributions towards our health – including prevention of bacterial pathogens entering our gut and causing infections.  Collectively, this huge population of microorganisms living inside our digestive tracts is often referred to as the ‘gut microbiota’.  If anything happens to us that disturbs or kills off members of this gut microbiota – such as exposure to antibiotics, or surgery – then we have greater vulnerability to gut infections, and particularly from a form of bacteria called Clostridium difficile.

Making the leap from PhD to postdoc

Following the annual Rising Scientist Day, Drs Myrsini Kaforou, Alex Thompson and Claire Byrne recount their experiences of becoming fully-fledged early career researchers and share their best advice for prospective postdocs.

The annual Rising Scientist Day at Imperial’s Hammersmith Campus offers PhD students the chance to share their research both with their peers, and a more general audience. In addition to poster presentations and networking opportunities, the showcase featured talks from those who had successfully made the transition from PhD to postdoc. (more…)

How machine learning will transform the way we look at medical images

Machine learning

Dr Tim Hoogenboom, a Research Sonographer, looks at the promise and perils of machine learning in medical imaging.

Medical imaging is key in today’s delivery of modern healthcare, with an immense 41 million imaging tests taking place in England in every year. Thousands upon thousands of patients safely undergo imaging procedures such as X-ray, ultrasound, and MRI every day, and the product of these tests – the images – play an essential role in informing the decisions of medical professionals and patients in nearly every area of disease.

Festive feasting: the good, the bad and the microbiome

Microbiome

In this festive post, Dr Anjali Amin looks at how to keep our gut microbiome happy over this period of indulgence.

As the festive season approaches, one wonders how our bodies prepare for the enormity of food that will be ingested in a relatively short space of time.  In the UK alone, the average person consumes 7000 calories on Christmas Day alone.  This is three times the recommended calorie intake per day, and most of us will have reached the recommended calorie intake before Christmas lunch has even been served. And of course, it’s not just about eating more. We are also a great deal more sedentary, with the average person in the UK spending 5.5 hours a day in front of the television over the Christmas period desperately awaiting reruns of Blackadder and yet another Christmas special!

World Osteoporosis Day: love your bones!

For World Osteoporosis Day, Dr Victoria Leitch provides an insight into how her research in osteoporosis is working towards new treatments for this common condition. 

As a young girl I spent many long afternoons in piano lessons.

Years later, I remember very little from the lessons – but I do vividly remember the teacher. She was very strict, had hair like candy floss and a severe hunch. She always made the lessons run long, but she would give me a chocolate bar if I helped her hang out her washing afterwards. She needed my help because she couldn’t reach the washing line anymore. One day I asked my mum why she had a hunched back and she told me it was because she had osteoporosis. At the time I didn’t really comprehend what that meant, but I knew it wasn’t good. One day she fell and broke her hip, and sadly, not long after that she passed away.  As you read my story, I am sure it sounds familiar to a lot of you. Maybe not with a piano teacher, but with a relative, family friend or neighbour. The reason I say that is due to the rising prevalence of osteoporosis – one in three women and one in five men over the age of 50 are affected. (more…)

The magic of crystallography

Light micrograph (LM) of Insulin crystals

Originally published in the Imperial Magazine in June 2017, Professor Naomi Chayen explains why, when it comes to medicine, crystals may indeed have magical properties.

To grow a crystal used to be considered a kind of magic. Perhaps that’s because crystals are so beautiful: it is easy to understand why so many people are fascinated by them and believe that they bring good fortune, or have healing powers. And yes, they do have powers. Crystallise a substance – a protein, for example – and you can understand its structure. We prize diamonds for their beauty: I prize protein crystals for their potential power to unlock new treatments, in everything from cancer to diabetes. They are my diamonds.
