“…Przy znacznym uszkodzeniu stawu i ścieńczeniu warstwy chrząstki szklistej można zaobserwować przewężenie szpary stawowej. Jak podkreślają autorzy licznych prac, dopiero dalsze stadia choroby manifestują się bardziej charakterystycznymi -wychwytanymi w klasycznym prześwietleniu, zmianami (13,14,55,69,84 (19).…”

Osteoarthritis (OA) is a degenerative disease of the joints, characterized by irreversible destruction of articular cartilage. The disease process is accompanied by changes of immunological nature, resulting in local inflammatory reactions, with the production of proinflammatory cytokines and metalloproteinases. There is currently no effective treatment resulting in repair of degraded cartilage. Clinical application of mesenchymal cells (MSCs) creates new possibilities in the treatment of incurable diseases. Multipotent MSCs exhibit immunosuppressive activity and limited immunogenicity and have the potential to differentiate in vitro towards adipocytes, osteocytes, chondrocytes, myocytes and endothelial cells. Thanks to these biological properties, they are increasingly used in clinical therapies. In few scientific papers, the safety of cellular therapies in the group of dogs diagnosed with OA has been confirmed. In patients undergoing treatment with autologous intra-articular injections, no serious adverse effects were observed, and in the vast majority of patients an improvement in the clinical condition and reduction of pain and joint pain were achieved. The paper presents the current state of knowledge on osteoarthritis in dogs, on the biological properties of adipose tissue stem cells and their use in OA therapy and on monitoring the progress of treatment by imaging diagnostics.

“…Single-photon emission computed tomography (SPECT) discovers clinical information related to human body structure characteristics. 10 Different sensors are employed in different imaging techniques to find imaging information of the same region of the body. As the applicability of medical image fusion is concerned, it is used in the detection of different diseases, such as cancer, Alzheimer's disease, glioma, etc.…”

Purpose:The technique of fusing or integrating medical images collected from single and various modalities is known as medical image fusion. This is done to improve the quality of the images and combine information from several medical images. The whole procedure aids medical practitioners in gaining correct information from single images. Image fusion is one of the fastest-growing research topics in the medical imaging field. Sparse modeling is a popular signal representation technique used for image fusion with different dictionary learning approaches. We propose a medical image fusion with sparse representation (SR) and block total least-square (BLOTLESS) update dictionary learning.Approach: The domain of dictionary learning is the most significant research domain related to SR. An efficient dictionary increases the effectiveness of sparse modeling. Due to SR being an ongoing interesting research area, the medical image fusion process is done with a modified image fusion framework with recently developed BLOTLESS update dictionary learning. Results:The experimental results are compared for the image fusion process using other stateof-the-art dictionary learning algorithms, such as simultaneous codeword optimization, method of optimal directions, and K-singular value decomposition. The effectiveness of the algorithm is evaluated based on image fusion quantitative parameters. Results show that the BLOTLESS update dictionary algorithm is a promising modification for the sparse-based image fusion with its applicability in the fusion of images related to different diseases. Conclusions:The experiments and results show that the dictionary learning algorithm plays an important role in the sparse-based image fusion general framework. The fusion results also show that the proposed improved image fusion framework for medical images is promising compared with frameworks with other dictionary learning algorithms. As an application, it is also used as a tool for the fusion of different modularities of images related to brain tumor and glioma.
