Age-related loss of muscle mass and function is common in the elderly and can lead to disability, loss of independence and increased risk of death. Sarcopenia is a key contributor to frailty and increased dependency in older adults (Cruz Jentoft et al., 2010) and thus is highly prevalent among institutionalized older adults (Bravo-Jose et al., 2018). Diet, specifically protein, has a role in the prevention and treatment of muscle loss in the older adult population nevertheless there is paucity of research on the effect of protein supplementation on lean body mass and other clinical outcomes in older adults in residential care (Donaldson et al., 2019) where the prevalence of muscle loss and weakness is reported to be high (Senior et al, 2015; Landi et al, 2012). Protein supplementation, in combination with exercise or additional nutritional supplements, has been shown to exert beneficial effects on muscle in community dwelling sarcopenic older adults (Kim et al., 2012, Bauer et al., 2015), albeit the effects of protein supplements alone have not been extensively studied in sarcopenic individuals. Muscle protein synthesis is influenced by both the amount and type of protein consumed (Pennings et al., 2011, Devries and Phillips, 2015).
The proposed PhD project aims to investigate the efficacy of a novel protein hydrolysate derived from the pelagic fish, blue whiting (Micromesistius poutassou), which to date has predominantly been used to produce protein hydrolysates for the feed industry. The proposed PhD project aims to evaluate the potential of a selected blue whiting protein hydrolysate (BWPH) to beneficially modulate markers of sarcopenia in free living community dwelling older adults (study 2) and older adults residing in care homes (study 3).
Study 1 Aim: A systematic review will be undertaken to investigate the efficacy of different protein sources on the risk of sarcopenia.
Study 2: Aim: To investigate the effect of blue whiting protein on whole body lean mass tissue and measures of muscle strength and functionality in free living community dwelling older adults.
Study 3: Aim: To investigate the effect of BWPH supplementation on whole body lean mass tissue and measures of muscle strength and functionality in older adults in care homes.
Design used for study 2 and 3
A double blind randomised parallel human intervention trial will be undertaken at UU to investigate the impact of consuming the BWPH on measures of muscle mass and function. The primary outcome of the study will be to measure differences in lean tissue mass between participants consuming BWPH and the control. Secondary measures will investigate changes in muscle functionality through the use of hand grip strength, ‘Timed get up and go’ test and 6 minute walk test. The impact of treatment on quality of life will also be investigated using the validated Short Form Health Survey version 2 (SF-36v2). Blood measures associated with sarcopenia (serum vitamin D status, proinflammatory cytokine profile) will be quantified and basic measures of general health will be assessed (full lipid profile as well as liver and kidney function tests). A four day weight food diary will be collected at baseline to determine habitual protein intake differences between the treatment groups. The recent physical activity questionnaire (RPAQ) will be complete at baseline and postintervention to determine each participant’s level of physical activity. A power calculation was based on data from Norton et al. (2015) in which a lean tissue mass difference of 0.61 kg between the protein group and placebo group with a 1.4 kg standard deviation (based on Borsheim et al. 2008) would require a minimum sample size of 38 participants per group. A final sample size of 75 per treatment group was selected to ensure sufficient sample size given the reported high dropout rate reported in previous studies (>50%) (Norton et al. 2015).

Completing the MRes provided me with a lot of different skills, particularly in research methods and lab skills.
Michelle Clements Clements - MRes - Life and Health SciencesWatch Video
I completed my undergraduate studies at Ulster University, where I graduated in 2017 with first class honours in Biomedical Science with a Diploma in Professional Practice . I joined the Diabetes Research group as a PhD researcher in September 2017 and completed my PhD studies in June 2020.I am proud to say I not only completed my PhD studies within 3 years, but also became the World Champion (with a perfect score!) in Irish Dance during my PhD studies. My favourite memory was the opportunity to present my PhD work at the EASD conference in 2019. If I could speak to myself at the start of my PhD, the best piece of advice I would give myself would be to enjoy every single minute as the time flies in. I really would do another PhD!
Sarah Craig - PhD in Biomedical Sciences
I completed my undergraduate studies in America at Texas Woman’s University where I majored in Kinesiology. I then moved to Scotland to successfully complete my Masters with Merit in Human Anatomy at the University of Dundee.My proudest moment was when I passed my viva! My favourite memory was …the dissections. I’ll never forget the friends I made and the good times we had together. I couldn’t have got through this without the support of my family, friends, lab colleagues, supervisors, and my boyfriend. If I could speak to myself at the start of my PhD, the best piece of advice I would give myself would be to write up after every experiment, keep a lot of back up copies of the work, and to enjoy the experience.

Poonam Singh Nigam - DSc in Biomedical Sciences
I started my PhD after I completed my undergraduate in Biology at Ulster University in 2016, with a dissertation project that focused on genetic variations in bacterial species. I continued using some of these techniques in my doctoral research, which primarily involved the investigation and development of mass spectrometry imaging in vitamin D treated prostate cancer, looking at the metabolic and genetic variations upon treatment. I worked with international collaborators at the University of Edinburgh and Maastricht University, where I got to learn and develop mass spectrometry techniques that have not previously been carried out in Northern Ireland. I now work as a postdoctoral researcher at the National High Magnetic Field Laboratory at Florida State University in Tallahassee, Florida, where I am helping to develop and implement a mass spectrometry imaging facility for users across the world with the super powerful 21T FT-ICR mass spectrometer.A PhD is a demanding process but when
Karl Smith - PhD in Biomedical Sciences
Throughout my PhD I’ve been provided with continuous support and guidance by my supervisors and the staff at the University.I’ve also received many opportunities to further enhance my professional development in the form of teaching experience and presenting my work at conferences which will aid in my pursuit of a career in academia or industry.
I graduated Ulster University in 2016 with a degree in Biomedical Science with DPP (Pathology). I was then offered a PhD studentship with Dr Catriona Kelly and Professor Neville McClenaghan at CTRIC which I started in September 2016. My PhD explored the pathophysiology of Cystic Fibrosis-Related Diabetes, the most common co-morbidity associated with Cystic Fibrosis.My proudest moment was undoubtedly passing my Viva (via Skype!), but I was also proud to be given the opportunity to present my work at the UK Cystic Fibrosis Trust Conference in 2018. Through this conference, I was able to meet with people with CF and the challenges they face which was important reminder that the research I was doing mattered. I couldn't have got through this without the unwavering support of my family, who were always there for me in the good times and the bad. I am also extremely grateful for the support and mentorship of my supervisors Dr Catriona Kelly, Professor Neville McClenaghan and Dr Dawood Khan
Ryan Kelsey - PhD in Biomedical Sciences
My proudest moment was when I knew the possibility of the full transfer of my PhD project to Ulster University, the University which I loved and started my first steps towards my PhD in, and also being a PhD graduate from one of the highly reputable universities such as Ulster is a big thing which I should always be proud of. I think there is no that word that can ever express my deepest thanks and sincere appreciation to my supervisor Professor Kathryn Burnett for her ideal supervision, valuable guidance, encouragement, generous help and ultimate support throughout my PhD project. I have been really lucky to have her as a supervisor. Also my deepest gratitude to Mr Linden Ashfield, Principal Clinical Pharmacist, Antrim Area Hospital (NHSCT) for his help and endless support throughout the whole research project. Also, I could not have got through this without the support of my beloved family (my father ”Sayed”, my mother ”Gamila”, my wife “Nermeen”
Ahmed Abuelhana - PhD in Biomedical Sciences
I graduated from Queen's University Belfast with a Master's in pharmacy in 2014 and subsequently began working as a community pharmacist in the Greater Belfast area. My career began to take an unusual turn when I got involved with a small startup company who developed a novel blood glucose monitor for diabetic patients. From here, my interest in diabetes was piqued and I applied for a PhD project (somewhat optimistically!) in the Diabetes Research Group at Ulster. Nearly four years later, I'm still there working as a postdoctoral researcher. Not bad considering I never thought I had a chance of getting a PhD spot!My time within the DRG has been, and still is, fantastic. I've made life-long friends (and surprisingly few enemies!) who have been patient, helpful and a joy to collaborate with. I couldn't have got through it without them (you know who you are). Likewise, the guidance from my supervisors, Prof. Peter Flatt and Dr. Nigel Irwin, has been invaluable. I'm probably most proud of
