Abstract. Objective. Short-stem total hip arthroplasty (THA) aims to preserve the proximal bone stock for future revisions, so that the first revision should resemble a primary intervention rather than a revision. This study aimed to compare the clinical and radiological outcomes in revision THA after failed short

Maintenance of acid-base homeostasis in extracellular fluids and in the cytoplasm is essential for the physiological activities of cells and tissues [1]. However, changes in extracellular pH (pHe) occurs in a variety of physiological and pathological conditions, including hypoxia and inflammation associated with trauma and cancer. Concerning bone tissue, if abnormal acidification occurs, mineral deposition and osteoblast differentiation are inhibited, whereas osteoclast formation and activity are enhanced [2]. Indeed, acidification, that usually occurs in the early phases of fracture repair, has been suggested as a driving force for regeneration via release of growth factors that act on the

Abstract. Objectives.
Worldwide, tendon disorders are one of the main causes of disability that decrease the quality of life of individuals and represent a substantial economic burden on society. Currently, the main therapies used for tendon injuries are not able to restore tendon functionality, and due to tendons' hypovascular and hypocellular nature, they present a reduced healing capacity, which also limits the success of the available therapies. In order to discover new therapies, extracellular vesicles (EVs), key players in cell-cell communication, have been widely explored for tissue engineering and regenerative medicine applications. Thus, the aim of this study is to assess the role of EVs derived from platelets in
Intervertebral disc degeneration can lead to physical disability and significant pain, while the present therapeutics still fail to biochemically and biomechanically restore the tissue.
Stem cell therapy is an effective means to address the repair of large segmental bone defects. However, the intense inflammatory response triggered by the implants severely impairs
Poor tendon repair is an unsolved issue in clinical practice, due to complex tendon structure. Tendon
For patients who took joint replacement, one of the complications, aseptic joint loosening, could cause a high risk of revision surgery. Studies have shown that MSCs have the ability of homing and differentiating, and also have highly effective immune regulation and anti-inflammatory effects. However, few studies had focused on the

Tendon diseases are prevalent health concerns for which current therapies present limited success, in part due to the intrinsically low regenerative ability of tendons. Therefore, tissue engineering presents a potential to improve this outcome. Here, we hypothesize that a concurrent control over both biophysical and biochemical stimuli will boost the tenogenic commitment of
