Article Citation - WoS: 1From Chemistry to Clinic: Polysaccharide-Bioceramic Composites for Tissue Engineering Applications(Mary Ann Liebert, Inc, 2025) Yakubogullari, Nilgun; Yilmaz-Dagdeviren, Hilal Deniz; Arslan-Yildiz, AhuComposite scaffolds combining polysaccharides and bioceramics represent next-generation scaffolds extensively investigated in tissue engineering (TE) and biomedical applications. Polysaccharides such as chitosan, hyaluronic acid, and pectin mimic the extracellular matrix components with their tunable physicochemical properties, enabling a favorable microenvironment for cell adhesion, proliferation, and cell-matrix interactions. On the other hand, bioceramics, including calcium phosphate, hydroxyapatite, and bioactive glasses, enhance the mechanical properties of the material and offer structural integrity and osteoconductive properties. While they have generally been preferred to be used in bone TE and dental applications, various studies have also demonstrated their potential in cartilage regeneration, wound healing, and broader biomedical applications. Recent advancements in material design and scaffold fabrication techniques, particularly 3D printing and electrospinning, have provided precise engineering of materials and fabrication of scaffolds for desirable mechanical properties and biological performance. These innovations foster the development of patient-specific scaffolds, thereby paving the way for applications in personalized medicine. This review critically summarizes alternative polysaccharides, bioceramics, and composite materials used in TE and biomedical applications. It also highlights advanced fabrication strategies and finally explores the translational potential of these biocomposites. By integrating emerging technologies, this review aims to provide alternative and sustainable materials for the development of next-generation scaffolds that meet clinical needs.Impact Statement This study introduces polysaccharide-bioceramic composites with enhanced mechanical and biological properties for tissue engineering. Beyond bone and dental repair, their applications increasingly extend to wound healing, cartilage, cardiac, and muscle regeneration with drug delivery, angiogenesis, and neurogenesis. By mimicking the native extracellular matrix, these composites support cell growth and tissue regeneration, offering a versatile platform for advanced regenerative therapies.Article Citation - WoS: 3Citation - Scopus: 4Biopatterning of 3d Cellular Model by Contactless Magnetic Manipulation for Cardiotoxicity Screening(Mary Ann Liebert, Inc, 2023) Önbaş, Rabia; Arslan Yıldız, AhuPatterning cells to create three-dimensional (3D) cell culture models by magnetic manipulation is a promising technique, which is rapid, simple, and cost-effective. This study introduces a new biopatterning approach based on magnetic manipulation of cells with a bioink that consists alginate, cells, and magnetic nanoparticles. Plackett-Burman and Box-Behnken experimental design models were used to optimize bioink formulation where NIH-3T3 cells were utilized as a model cell line. The patterning capability was confirmed by light microscopy through 7 days culture time. Then, biopatterned 3D cardiac structures were formed using H9c2 cardiomyocyte cells. Cellular and extracellular components, F-actin and collagen Type I, and cardiac-specific biomarkers, Troponin T and MYH6, of biopatterned 3D cardiac structures were observed successfully. Moreover, Doxorubicin (DOX)-induced cardiotoxicity was investigated for developed 3D model, and IC50 value was calculated as 8.1 μM for biopatterned 3D cardiac structures, which showed higher resistance against DOX-exposure compared to conventional two-dimensional cell culture. Hereby, developed biopatterning methodology proved to be a simple and rapid approach to fabricate 3D cardiac models, especially for drug screening applications.

Although pneumatic compression therapy (PCT) is one treatment option, current algorithms consider it as an adjunct to standard LE. The purpose of this study is to evaluate the importance of adapting PCT for lower extremity LE (LEL) in relation to patient compliance and rate of infection.</p> Materials and Methods: Patients diagnosed with LEL were followed prospectively. Patient demographics, comorbidities, treatment modality, compliance, infection due to LE, and hospitalization were recorded. LEL patients with no-PCT were also recorded in the same time period to evaluate the treatment compliance and the need for physical therapy visits. The no-PCT group received the standard LE care, whereas the PCT group received the standard LE care plus a new-generation pneumatic compression device.</p> Results: A total of 69 patients were enrolled in this study. The PCT group had 50 patients and no-PCT group had 19 patients. The PCT group had median 58.5 months of LE symptoms, while non-PCT patients had median 23 months of LE symptoms (p = 0.11). Infection rates decreased by 32% and hospitalizations due to infection decreased by 14% after PCT treatment had been initiated. Physical therapy needs decreased by 24% after PCT use. At median 18 months, follow-up compliance for PCT was 84%, but compliance for manual lymphatic drainage was almost half (53%) in no-PCT group.</p> Conclusions: PCT leads to a decrease in infection rate, hospital admissions, and physical therapy (PT) visits in clinically significant LEL. Although there is no cost calculation in this study, it can be correlated to significant cost savings due to a reduction of infection and hospitalization and the need for PT visits. Adoption of PCT offers a superior value proposition to not only patients but also the health care system. Cost analysis should be followed.</p>
