[Evaluation of the effect of cattle calcined bone grafting material to repair alveolar bone defect after tooth extraction].

Purpose: To verify the efficacy and safety of calcined cattle bone grafting material in filling alveolar bone defect after tooth extraction.

Methods: A randomized, bind, parallel, positive-control multicenter clinical trial was conducted. A total of 280 subjects were randomly assigned to either the experimental group (calcined cattle bone group) or control group (Bio-Oss group) equally.

Chronic minocycline treatment exerts antidepressant effect, inhibits neuroinflammation, and modulates gut microbiota in mice.

Rational: Minocycline is a second-generation, semi-synthetic tetracycline, and has broad spectrum-antibacterial activity. Interestingly, many studies have demonstrated that minocycline is beneficial for depression, which may be due to its effects on neuroinflammation modulation. Recently, gut microbiota imbalance has been found in depression patient and animal models.

Chronic minocycline treatment reduces the anxiety-like behaviors induced by repeated restraint stress through modulating neuroinflammation.

Anxiety disorders are chronic, disabling conditions across the world, and bring a great burden to individuals and society. Although advances have been made in understanding of the pathophysiology of these diseases, no mechanistically new drugs for anxiety disorders have reached the market in the past two decades. Some evidence indicates that stress increases neuroinflammatory signaling, which is related to the development of anxiety and depression.

The octanol/water distribution coefficients of ardipusilloside-I and its metabolites, and their permeation characteristics across Caco-2 cell monolayer.

Background: Ardipusilloside-I (ADS-I) is a triterpenoid saponin extracted from Chinese medicinal herb Ardisiapusill A. DC. Previous studies have demonstrated the potent anti-tumor activities of ADS-I both in vitro and in vivo, and its main metabolites (M1 and M2) from human intestinal bacteria.

Efficacy of local delivery of ardipusilloside I using biodegradable implants against cerebral tumor growth.

Ardipusilloside I (ADS-I) is a natural compound that can be isolated from the Chinese medicinal herb Ardisiapusilla A.DC, and has been reported to inhibit the growth of glioblastoma cells in cultures. This study was designed to test its efficacy by the delivery using biodegradable implants against glioblastoma in vivo.
