Aberdeen scanner study could improve brain tumour treatments
Scientists at the University of Aberdeen and NHS Grampian have secured funding to generate never-before-seen brain tumour images with the aim of improving treatment.Half of all glioblastoma patients die within 15 months of diagnosis even after surgery, radio and chemotherapy.MRI scans used to monitor a tumour's behaviour can be imprecise but it is hoped the Field Cycling Imaging (FCI) scanner - developed in Aberdeen - will give clinicians better information.The £350,000 in support - from the Scottish government - will fund a trial which will be carried out on a group of 18 patients.
MRI scanners were invented at the University of Aberdeen 50 years ago, but the new FCI scanner is the only one of its type used on patients anywhere in the world.It can work at low and ultra-low magnetic fields which means it is capable of seeing how organs are affected by diseases in ways that were not previously possible.It can vary the strength of the magnetic field during the patient's scan - acting like multiple scanners and extracting more information about the tissues.The new technology can detect tumours without having to inject dye into the body, which can be associated with kidney damage and allergic reactions in some patients.The team of doctors and scientists involved will scan glioblastoma patients undergoing chemotherapy after surgery and chemoradiotherapy.
It is hoped the research will establish that, unlike conventional MRI scans, FCI can tell the difference between tumour growth and progression, and "pseudo-progression" which looks like a tumour but is not cancerous tissue.Prof Anne Kiltie, chair in clinical oncology at the University of Aberdeen, who is leading the study, said: "We already have evidence that FCI is effective in detecting tumours in breast tissue and brain damage in stroke patients."Applying this exciting new technology to glioblastoma patients could give us a much more accurate and detailed picture of what is going on in their brain."If we can detect true tumour progression early, we can swap the patient to a potentially more beneficial type of chemotherapy."Providing certainty will also reduce anxiety for both patients and relatives and improve the quality of life of patients."Prof Kiltie's role at the university is fully funded by the charity Friends of ANCHOR through its Dream Big appeal.Chief executive Sarah-Jane Hogg welcomed the "really promising" development and thanked donors and fundraisers for their support.

Korean skincare cured my acne, made my skin softer & banished redness – now I'm opening Scotland's first K-beauty shop
IF you've been keeping up with the goings on in the world of skincare in the last couple years, then Korean trends will certainly be on your radar. It has been popular in the West for decades, but TikTok has taken the craze to a whole new level. 2 2 The trending 'glass skin' look is perhaps why K-beauty is on every beauty fan's radar, but it's the quality of the products that keeps them buying. And nobody knows this better than Korean skincare expert Lauren Miller who has been using the innovative buys for five years. Lauren first discovered K-beauty while working in the operating theatres at a busy hospital during Covid. The Scots mum's skin "really suffered" from wearing PPE all day so when she stumbled across an advert for Korean products she decided to give them a go - and they have completely transformed her skin. She told Scottish Woman Magazine: "My acne improved, my skin was softer, and my redness and irritation were gone. It changed my life, and I wouldn't use anything else on my skin now. "It's almost addictive, with so many brands and products to choose from – but with ingredients to treat so many skin problems, there really is a product for everyone." And Lauren is now opening Scotland's first Korean skincare store, Wee Ghost Beauty, in Glasgow later this month. She said: "In Scotland, we can have all four seasons in one day and our skin can really suffer. I believe Korean skincare is the answer we've all been looking for. I want my customers – no matter what their budget is – to be able to buy from Wee Ghost Beauty. Quality skincare should be accessible to all, and I believe that is where Korean skincare stands out from the crowd. "Even in the less expensive brands you will still find the best ingredients and a huge range of products, so it appeals to beginners and enthusiasts of all ages and budgets." I let my kid start wearing make-up aged 3 - I've spent £1.5K on her 200 products & her skincare regime has 9 steps Korean skincare places particular emphasis on hydration, skin barrier repair, brightening, and anti-ageing. The use of microbiome and probiotic ingredients is also popular. Korean skincare routines can be up to 10 steps and double cleansing is always a must. And sought-after K-beauty products often contain innovative ingredients you might not have come across before, such as snail mucin - the mucus secreted by snails. You might be put off by the idea, but lovers of this slimy skincare craze claim products containing snail mucin leave their face glowing and hydrated. Other ingredients you might not have seen incorporated into skincare before include ginseng and bean essence.

'Pioneering' new scanner used for brain tumour patients trialled in world-first
A "pioneering" new scanner derived from MRI technology could be used to track brain cancer spread and lead to improved treatment for patients, scientists have said. Researchers at the University of Aberdeen and NHS Grampian have been awarded £350,000 funding by the Scottish government to generate never-before-seen images of glioblastoma brain tumours. It is hoped the technology will improve treatment and quality of life for patients by investigating a new way to scan the tumours. Glioblastoma is the most common and aggressive type of brain tumour with more than 3,000 new patients in the UK diagnosed each year. The University of Aberdeen said half of all patients die within 15 months of diagnosis even after extensive surgery, radiotherapy and chemotherapy. Field cycling imaging (FCI) is a new and specialist type of low-field MRI scan pioneered in Aberdeen and has already been found to be effective in detecting tumours in breast tissue and brain damage in stroke patients. It is hoped it can now be used to help brain tumour patients. Full body MRI scanners were invented at the Scottish university 50 years ago, but the FCI scanner is the only one of its type used on patients anywhere in the world. The FCI derives from MRI but can work at low and ultra-low magnetic fields, which means it is capable of seeing how organs are affected by diseases in ways that were previously not possible. It can also vary the strength of the magnetic field during the patient's scan - acting like multiple scanners and extracting more information about the tissues. The tech can detect tumours without having to inject dye into the body, which can be associated with kidney damage and allergic reactions in some patients. Those involved in the project will scan glioblastoma patients undergoing chemotherapy after surgery and chemoradiotherapy. It is hoped the research will establish that, unlike conventional MRI scans, FCI can tell the difference between tumour growth and progression, and "pseudo-progression" which looks like tumour but is not cancerous tissue, which could improve care and quality of life. The new tech was described as "another example of the pioneering work coming out of the University of Aberdeen", by the charity Friends of ANCHOR. Professor Anne Kiltie, who is leading the study, said: "If we can detect true tumour progression early, we can swap the patient to a potentially more beneficial type of chemotherapy. "Also, being able to verify that a patient has pseudo-progression will prevent effective chemotherapy being stopped too early, because it was thought that the tumour has progressed, thus worsening prognosis. "Providing certainty will also reduce anxiety for both patients and relatives and improve the quality of life of patients. "Importantly, having a reliable method to identify progressive disease will allow development and more precise evaluation of emerging potential treatments. This is of particular importance as patients currently have a limited choice of treatments for combating their cancer. Scotland and beyond."
