Winner at EuroPhysiology 2018!
Congratulations to Physiology graduate Norita Gildea who won the Early Career poster competition for the ‘Human & Exercise Physiology’ Theme at EuroPhysiology 2018 conference. Her poster was titled ‘Time course adaptations in oxygen uptake and muscle deoxygenation kinetics during submaximal exercise subsequent to a 12 week moderate-intensity continuous training or low-volume, high-intensity interval training intervention in type 2 diabetes.’
Human Health and Disease BSc students undertake Medical Supply Company-sponsored summer research placements
Junior Sophister HHD students, Eva Kelly and Lucy Fitzgerald were selected to undertake summer placements in the laboratories of Prof. Mani Ramaswami and Prof. Ed Lavelle. The awards were generously sponsored by Medical Supply Company.
“This summer I spent four weeks assisting in Professor Ramaswami’s lab in TCIN. I was lucky enough to be offered this internship through my course (Human Health and Disease) which currently facilitates two lab placements for JS students. During my time in the lab I helped carry out important research which focused on a new plasmid-killer red. The aim was to see how much light was needed in order to cause damage to the cells without killing them. It is hoped that this research will ultimately enable this killer red to be used to mimic the damage caused
in diseases such as ALS. During the internship I learned valuable skills and gained vital first hand experience of the inner workings of a research lab. My first week was mostly spent observing, learning and practicing new techniques. As the weeks passed I began to master these and became confident and sufficiently competent to carry out the experiments by myself. HHD offers lots of exposure to current research. However the placement put theory into practice and showed research as it happens. It demonstrated clearly the skill set that is required for research beyond academic knowledge. I discovered that critical thinking and problem solving is needed on a daily basis-as things often don’t go according to plan! New ideas are always vital and thinking outside the box is critical when interpreting data and forming conclusions. The placement was extremely valuable due principally to the effort the researchers went to ensure that I gained maximum insight into their research. Their enthusiasm for their work was infectious, and I very indebted to them, and to Prof Ramaswami, for providing me with this valuable experience.”
"I was extremely fortunate to be the student chosen to gain experience in the lab of Professor Ed Lavelle. Spending one month in a research lab was more beneficial than I could have imagined; towards my degree in Human Health and Disease as it gave me an insight into what my fourth year lab based project might be like, and towards building my confidence in the workplace and expanding my scientific knowledge. As well as this, it gave me an insight into the career of a research scientist, a career that any HHD student may choose, and one that I am keen to pursue having completed my placement. During my time in the lab I gained knowledge of many important techniques used in many areas of biology, including tissue culture, cell plating and cell counts, ELISA, real time polymerase chain reaction (PCR), while also attending very valuable flow cytometry classes. Along with these useful techniques, I had the opportunity to use more specific techniques to the research in Prof Lavelle’s lab, including obtaining a single-cell suspension from a mouse spleen, as well as murine bone-marrow dendritic cell isolation. These skills were essential for the topic which myself, along with the help of my supervisors were keen to investigate; the role of the adjuvant chitosan, an activator of the inflammasome, which plays a role in the cGAS-STING pathway to induce type 1 IFN production. The research I partook in was focused on the mechanism by which chitosan induces mitochondrial stress, increasing levels of ROS. The overall experience was extremely positive, highlighting to me the support systems in place within a lab environment, with PhD students and post doctorates sharing ideas. This opportunity also emphasised the importance within the science world to keep up to date with the research in other labs and their progress, by attending conferences and reading journals. I would highly recommend applying for summer lab placement to any student who wants to experience hands on the work of a research scientist. Whether you want to test out if you are suited to the work, or simply want to gain beneficial experience in the area before leaving college, I would encourage you to put yourself out there and witness the overwhelmingly positive experience to be gained from a summer lab internship."
We thank Medical Supply Company for the generous sponsorship of these summer research placements.

|Nature Nanotechnology - Prof. Maeve Caldwell|
Prof Maeve Caldwell and colleagues, Department of Physiology and Trinity College Institute for Neuroscience, together with colleagues from the University of Bristol and the US have shown that nanoparticles can transmit biological signals through a cellular barrier resulting in DNA damage to neurons and astrocytes. Interestingly the presence of astrocytes exacerbated the damage to neurons. The team report changes caused by nanoparticles in the natural cellular pathway, autophagy, and increases in the levels of the cytokine interleukin-6 (IL-6).
The potential for maternal nanoparticle exposures to cause developmental toxicity in the fetus without the passage of nanoparticles has previously been shown. We now demonstrateexposure of CoCr nanoparticles to BeWo cell barriers, a human in vitro model of the human placenta, triggers an impairment of autophagic flux and the release of the proinflammatory factor IL-6. This contributes to an altered differentiation of human neuroprogenitor cells plus DNA damage in the derived neurons and astrocytes that is mediated by the astrocytes. Inhibiting autophagic degradation in the BeWo barrier by overexpression of a dominant-negative human ATG4BC74A significantly reduces the levels of DNA damage in astrocytes. In vivo, indirect nanoparticle toxicity in mice also results in neurodevelopmental abnormalities with reactive astrogliosis and increased DNA damage in the fetal hippocampus. This demonstrates the potential importance of autophagy in eliciting nanoparticle toxicity and the risk of indirect developmental neurotoxicity following maternal nanoparticle exposure.

RAMI Section of Biomedical Sciences Annual Meeting, 22nd June 2017
The Royal Academy of Medicine in Ireland’s Section of Biomedical Sciences Annual Meeting was hosted by TCD Physiology in the Trinity Biomedical Sciences Institute on 22nd June 2017. The day started with a welcome address from the Section President Prof Veronica Campbell (TCD) followed by the opening of the Donegan Medal competition by the Section Secretary Prof. Ken O’Halloran (UCC). Twelve first-time presenters battled for the Donegan Medal and the standard was so high that both winner (Deirdre Scully UCD and Nicola Kavanagh RCSI) and runner-up places (Orla Haugh TCD and Bibiana Mota TCD) were shared. A first for the meeting! A jam-packed poster session with contributions from RCSI, UCD, TCD, UCC, Dundalk and DCU along with many national and international collaborators kept us busy during coffee time – a really great festival of science. A respite from competition allowed us to thoroughly enjoy the Conway review lecture delivered by Dr. Stephen Keely (RCSI) who provided a fascinating account of bile acids through the ages, from traditional Chinese medicine to current-day therapeutics. Oral communications followed from Dr. Gerard O’Keeffe (UCC), Michelle Smith (UCD) and Sarah Wade (TCD). The competition kicked off again for the Barcroft Medal where we were treated to some riveting data delivered by postdoctoral researchers from as far flung as the University of Nevada! The breadth of topics was extensive and included Parkinson’s disease, autoimmunity, breast cancer and immune metabolism culminating in calcium signalling stealing the show with a well-deserved winner in Dr. Bernard Drumm. After an intensive deliberation by the judges, the prize-giving ceremony was held at the wine reception and winners were bestowed with their prizes by the Section President and Secretary. The scientific dialogue continued over dinner at Quay 16 where we consolidated our newly acquired knowledge – a deeply enjoyable day!

Professor M. Lynch awarded SFI grant
Prof. Lynch, Dept of Physiology, has been awarded €1.38 for the research project "Targeting glial plasticity to alleviate age-related loss of neuronal function in Alzheimer’s disease"
The aims of this project are
To identify novel markers, with an emphasis on metabolic changes, which reflect microglial activation and functional state. The ultimate objective is to utilize these markers to develop MRI tools and therefore assess changes with age, in particular in a mouse model of Alzheimer's disease, in a non-invasive manner.
To establish whether the age-related loss of glial plasticity correlates with a shift in their metabolism that impacts on synaptic density and thereby on synaptic function.
To assess the potential beneficial effects of 4 strategies designed to reprogramme glia in alleviating the deficits that develop with age and in Alzheimer's disease.

Embryology is a core subject undertaken by Health Science students, with the aim to bring together core knowledge in Cell Biology, Anatomy and Physiology to describe the developmental process from fertilization to birth. For the 2015-16 academic year student feedback indicated difficulty visualising key embryological concepts in 2D, particularly embryonic folding/flexion and cell layer migration during gastrulation. This project will develop an interactive audio-visual animation that will be implemented into the Junior Freshman curriculum for teaching embryology and will be assessed via pre- and post- animation surveys to determine if the audio-visual aid improves student learning in embryology. Furthermore, the collation of questionnaire data associated with the animation will be conducted by a Senior Sophister student as part of their final year undergraduate research project. Overall, this will explore how the animation can be used to supplement student education beyond the traditional classroom. This project will act as the first steps to develop a prospective pilot animation, which will be introduced in 2016-17, and will act as a platform to develop/implement new audio-visual teaching tools into degree programmes throughout the School/Faculty, including Medicine, Nursing and Occupational Therapy.

TBSI image competition - 1st place for Physiology post grad.
Maria Velasco from Prof. Kumlesh K.Dev's Lab, Dept of Physiology, wins 1st place for her image: "Cerebellar neuron-glia network "
This image represents the cellular organization between neurons and glial cells in a mouse cerebellar organotypic slice. Organotypic cultures of brain tissue allow you to study different parts of the brain –e.g. the cerebellum- in their original structure, keeping the cellular organization and neuronal networks almost as they are in vivo. This can be used to study different development features of the brain in vitro, as well as to perform electrophysiological and pharmacological experiments. In the brain, neurons are outnumbered by glial cells, amongst we can distinguish astrocytes, microglia and oligodendrocytes. Here it is shown the interaction between neurons (red), astrocytes (yellow) and microglia (green) in one of the lobules of the cerebellum. The imaging is done by confocal microscopy with the Leica SP8 microscope in TBSI. This image is 300µm wide.

AMBER image competition - 3rd place for Physiology post grad.
Sibylle Bechet from Prof. Kumlesh K.Dev's Lab, Dept of Physiology, wins 3rd place for her image: "Stop Twitching - Start Smyelin"
This fluorescent image was generated using confocal microscopy. It depicts the complex interplay of glial and neuronal cells in the cerebellum of a Twitcher mouse, an animal model for Krabbe’s Disease (KD). This infantile neurodegenerative disease affects all cell types in the brain and is mainly characterised by accumulations of a toxic metabolite called psychosine. This, in turn, is detrimental to oligodendrocytes, causing dismantling of their protective myelin sheath around neurons. Although clinical practice lacks a curative treatment, emerging evidence suggests beneficial effects of pre-treatment with fingolimod, a drug used for the treatment of Multiple Sclerosis. In this image, oligodendrocytes (green), neurons (red) and astrocytes (yellow) were stained using immunohistochemistry, in order to monitor effects of treatment with fingolimod in the Twitcher mouse. This technique allows evaluating this compound as a potential candidate for treating this devastating childhood illness.

Trinity College launches new free online course: “Exercise Prescription for the Prevention and Treatment of Disease”
"Exercise Prescription for the Prevention and Treatment of Disease", Trinity’s newest free Massive Open Online Course (MOOC), run in partnership with FutureLearn, begins on the 18th of April 2016.
This two week free online course from Trinity College Dublin will explore the evidence behind exercise prescription, and how it has evolved as a tool for preventing and treating disease. Geared towards healthcare professionals, the course details how physiological adaptations to exercise can translate to improved health outcomes, and will help enhance confidence in exercise prescription as a treatment.
Assistant Professor of Physiotherapy Dr Cuisle Forde explains, “Not that long ago bed rest was prescribed to patients with cardiovascular and respiratory disease, and exercise was considered by many health professionals as something to be avoided. Today, exercise is an integral part of patient treatment”.
The free online course will address the role of exercise in the treatment of a variety of clinical populations including people with cardiovascular disease, mental health problems, paediatric conditions and cancer.
Available to anyone with internet access across multiple devices including desktops, tablets and smartphones, the two-week innovative course will enable healthcare professionals anywhere to experience a Trinity education. Throughout the course there will be an opportunity to engage with researchers, healthcare professionals and exercise prescription experts from the discipline of Physiotherapy and the Department of Physiology at Trinity College Dublin.
Head of Physiology Dr Aine Kelly says "One of the best things about this course is that it is accessible to health care professionals who feel they need to increase their working knowledge and awareness of the latest research in exercise prescription for patient populations."
This course is designed for healthcare professionals who wish to broaden their understanding of exercise prescription and physical activity as a tool to prevent and treat disease, but no previous experience or qualifications are required.
Register for this free online course which starts on the 18th of April here: https://www.futurelearn.com/courses/exercise-prescription/1/
