Background: Tectochrysin suppresses several diseases. In this study, we aimed to explore the effects of tectochrysin ona rat model of periodontitis PDS).

Methods: Male Sprague-Dawley (SD) rats were subjected to ligature to induce periodontitis.

Background: The Fangcang shelter hospital has gradually become the primary management mode in China's fight against this Corona Virus Disease 2019 (COVID-19) in 2020. In early 2022, the Fangcang shelter hospital management model was successfully applied to the new outbreak of COVID-19 in Shanghai also. Although Fangcang shelter hospitals are no longer the prevailing mode of prevention of COVID-19, the management experience of Shanghai makeshift hospitals is worthy of reference for public health.

Introduction: Blood supply remains one of the obstacles to large bone tissue engineering. This study aimed to generate vascularized bone tissue by inducing axial vascularization into a construct combining natural coral scaffold and a bone marrow mesenchymal stem cells (BMSCs) sheet.

Material And Methods: Isolated BMSCs were cultured to form an osteogenic cell sheet using a continuous culture method.

Techniques that use sheets of cells have been successfully used in various types of tissue regeneration, and platelet-rich fibrin (PRF) can be used as a source of growth factors to promote angiogenesis. We have investigated the effects of the combination of PRF and sheets of mesenchymal stem cells (MSC) from bone marrow on the restoration of bone in critical-size calvarial defects in rabbits to find out whether the combination promotes bony healing. Sheets of MSC and PRF were prepared from the same donor.

Aims: To analyze the effects of platelet-rich fibrin (PRF) on mesenchymal stem cells (MSCs) in vitro and investigate in vivo bone formation by MSC sheets with PRF.

Materials And Methods: Cell proliferation and expression of osteogenesis-related genes within MSC sheets were assessed upon exposure to PRF from the same donors. We then injected MSC sheet fragments with or without PRF subcutaneously in nude mice and assessed bone formation by micro-computed tomography and histological analyses.
