Around this time of the year we are usually asked by our Institute and Theme leads to summarise our activities over the past 12 months. I have just submitted our outputs (below) and I wanted to say

Thank you all very much for being an excellent team, great friends and amazing scientists!

Here’s Pirog lab activity 07/2024-07/2025

Grants:

• MRC Drug repurposing for bone diseases (co-PI)

Prizes:

• Anna Porter, Orthopaedic Trainee and PhD student in Pirog lab, won the prestigious Kreibich prize this year presenting her PhD project on tissue engineering approaches to investigate molecular mechanisms in hemiepiphysiodesis.

• Roufaida Bouchenafa, PhD student in Pirog lab, received a bursary from the British Society for Matrix Biology to attend the Matrix Biology Europe meeting in Lyon in September 2024

Impact:

• Kasia Pirog organised, contributed funding and presented (together with Roufaida Bouchenafa) at the annual Genetics Matters public engagement conference organised as part of the International Rare Disease Day and showcasing the activities of the Newcastle Centre for Rare Disease. With 65 attendees (local schools, general public, patients and patient organisations) and 30 enthusiastic scientists, a wonderful panel debate on achievements and challenges in rare disease research moderated by the NUCore Rare Disease Policy Manager Victoria Hedley, exciting hands-on experiments (building a 3D skin model, DNA extraction, osteoarthritis and chondrodysplasia diagnosis, muscle MRI scans, art installations and many more) and lovely food, the event was a great success.

Here’s to another amazing year ahead!

We’re playing with polarising microscopes today. Here’s an image of collagen fibers in porcine articular cartilage, acquired by João. Isn’t it awesome?

Huge congratulations to Anna Porter, Orthopaedic Trainee and PhD student in our lab, who won the prestigious Kreibich prize last week, presenting her PhD project on tissue engineering approaches to investigate molecular mechanisms in hemiepiphysiodesis.

Our PhD student Marc Farcasanu successfully defended his PhD thesis yesterday. The viva was conducted by Dr James Henstock from Northumbria University and Dr Priscila Melo from Newcastle University – thank you both for acting as Marc’s examiners.

Well done Marc!

Congratulations on the successful defence of your thesis and the recent paper publication. It has been a pleasure working with you and we wish you all the best in your future endeavours. Please don’t be a stranger and keep in touch!

We heard a great talk by Dr Michal Dudek, a Research Fellow at the Wellcome Trust Centre for Cell Matrix Research at the University of Manchester, discussing the interplay between circadian rhythm, mechanical loading, osmotic and heat stress in cartilage and intervertebral disc. Thank you Michal for visiting us and sharing your work!
