Background: Ectopic replantation and regeneration of splenic tissue fragments following splenic trauma or splenectomy is known as replantation of splenic tissue. It typically takes place in the abdominal cavity, however, splenic tissue replantation in the liver is extremely rare and difficult to diagnose. It is often misdiagnosed as a liver tumor and removed.

Emergency Department, Loma Linda University, Loma Linda, CA, USA.
Open fractures that produce an extruded long bone diaphysis, such as this case, are an exceedingly rare incident, with even fewer cases documented, leading to difficult medical decision-making for the operative management of such situations. Options for operative management include replantation following sterilization of the extruded fragment, bone transport, a vascularized fibular graft, and even allograft reconstruction. Each option is associated with high and variable levels of risk.

Introduction: Thrombosis is the most common complication of thrombocytosis, which can be particularly damaging to reattached digits. We present a guideline about digital replantation when thrombocytosis is expected.
Case Presentation: We report a case of an 18-year-old man who sustained a traumatic amputation of two fingers and splenic rupture in a traffic accident.

Objective: To evaluate the effect of a novel micro-arc oxidation (MAO) coated magnesium-zinc-calcium (Mg-Zn-Ca) alloy scaffold/autologous bone particles to repair critical size bone defect (CSD) in rabbit and explore the novel scaffold corrosion resistance and biocompatibility.
Methods: Seventy-two New Zealand white rabbits were randomly divided into 3 groups ( =24), group A was uncoated Mg-Zn-Ca alloy scaffold group, group B was 10 μm MAO coated Mg-Zn-Ca alloy scaffold group, and group C was control group with only autologous bone graft. The animals were operated to obtain bilateral ulnar CSD (15 mm in length) models.
Mesenchymal dental pulp cells attenuate dentin resorption in homeostasis.

Center for Craniofacial Regeneration, Columbia University, New York, NY, USA
Dentin in permanent teeth rarely undergoes resorption in development, homeostasis, or aging, in contrast to bone that undergoes periodic resorption/remodeling. The authors hypothesized that cells in the mesenchymal compartment of dental pulp attenuate osteoclastogenesis. Mononucleated and adherent cells from donor-matched rat dental pulp (dental pulp cells [DPCs]) and alveolar bone (alveolar bone cells [ABCs]) were isolated and separately cocultured with primary rat splenocytes.
