This summer I traveled to London, England to
work at the
Royal Free and University Medical School in Hampstead.
Hampstead is a quiet suburb, 10 minutes north of Central
London. Hampstead is known for its high priced real estate.
One of the main attractions in Hampstead is a large park
Hampstead Heath. Londoners travel to the Heath in an
attempt to escape the fast-moving pace and crowded surroundings
common to Central London. It offers magnificent views
of the city skyline, especially at sunset. And when the
weather is nice (which unfortunately didn’t happen
until I was about to leave) there are ponds for swimming.
I often found myself, especially after the London bombings,
amongst many others staring at the proud, beautiful city
that withstood a terrorist attack.
Although I did get out to see the sights of London, most
of my time was spent working in the lab of Dr.
Alan Phillips in the department of Paediatric
Gastroenterology (and
no, that is not a typo, pediatric does have an “a”).
My desire to go to London stems from my research and
a specific test called the in vitro organ culture assay
(IVOC) that is performed by Dr. Phillips and his colleagues.
The IVOC assay employs tissue obtained from biopsies
of children being investigated for gastro-intestinal
diseases at the hospital’s clinic. During the endoscopy
procedure, a small sample of duodenum tissue is removed
from the patient. This procedure has full ethical board
approval and no tissue can be taken without consent from
the families involved. The tissue must also be screened
to ensure it is not inflamed before it can be used in
the assay to ensure it resembles normal intestinal conditions.
Once suitable tissue samples are obtained, they are inoculated
with an overnight culture of E.coli. The strains I chose
to test were those used in Dr. Jorge Giron’s lab
at the Department of Microbiology and Immunology. Several
strains of enteropathogenic E. coli (EPEC) were screened
for the presence or absence of adherence to the surface
of intestinal cells. Each strain had to be repeated three
times for consistency, and at eight hours per assay that
equals a lot of hours in the lab. However, I enjoyed
my long days in lab. Yes, London had much too offer,
but so did my lab mates, all of whom were very friendly
and were excited to learn about America as well as to
teach me about their cultures and backgrounds. Within
my lab group, there were people from places like Singapore,
Zambia, Germany, Spain, as well the UK. Some of my favorite
moments in the lab were when we all would try to learn
each person’s native language and then laugh at
how silly we all sounded.
Much of my time in lab was spent learning to use the
scanning electron microscope (SEM). After the IVOC assay
is completed, the samples must be processed and mounted
for viewing in the SEM to screen for adherence. This
process takes about two additional days. First, the samples
must be fixated and dried in a machine that combines
very high pressure and very high temperature in order
to dry the specimen. Then the sample is mounted on an
aluminum stub. During this step the samples become very
brittle and can easily “jump” off the table,
to be lost forever. Once they are mounted, the stub is
sputter coated with argon and is ready for viewing in
the SEM.
One factor that made my day at the lab easier was that
my flat was just a few steps away. Although there was
no TV, no internet, and a phone that would only call
the hospital, it was still a place to call home. My five
flat mates were amazing individuals, who like my lab,
were all from different countries. Who would have known
I would eat Indian food spicier than anything I had ever
tasted and teach English to a Syrian while in London?
It was usually in our shoebox size kitchen that we would
all gather to taste the Indian meal my flat mate prepared
or to discuss our different cultures and languages.
There is so much to see and do in a city of 9 million
people that comprises ethnic groups from all corners
of the world. Unfortunately, though, London offers too
much to be fully appreciated in just one summer. From
museums, to the theaters, castles and countryside, the
attractions are endless. The anticipation surrounding
the Live 8 concert and the 2012 Olympic Games announcement
were moments in history that I was honored to be a part
of. I would like to send a special thank you to Dr.
Giron and Dr. Phillips and
all those in their laboratories. Also a special thanks
to Carol Bender and the BRAVO!
Program for this wonderful opportunity.
