Characterization of calcifications in posterior horn of human meniscus using micro-computed tomography

Ville‐Pauli Karjalainen, Iida Hellberg, Aleksandra Turkiewicz, Bijay Ratna Shakya, Nodira Khoshimova, Eeva Alina Nevanranta, Shuvashis Das Gupta, Khaled Elkhouly, Amanda Sjögren, Mikko Finnilä, Patrik Önnerfjord, Velocity Hughes, Jon Tjörnstrand, Martin Englund, Simo S. Saarakkala

This study uses micro-CT to identify and quantify differences in calcification patterns between basic calcium phosphate and calcium pyrophosphate in human meniscus, providing insights into their roles in osteoarthritis.

Altered co-expression patterns of synovial fluid proteins related to the immune system and extracellular matrix organization in late stage OA, compared to non-OA controls

Jenny Lönsjö, Martin Rydén, Aleksandra Turkiewicz, Velocity Hughes, Jon Tjörnstand, Patrik Önnerfjord, Martin Englund, Neserin Ali

The paper identifies differentially expressed proteins and altered co-expression patterns in synovial fluid of end-stage OA patients compared to non-OA controls.
