Root-shaped antibacterial alginate sponges with enhanced hemostasis and osteogenesis for the prevention of dry socket.

Tooth extraction commonly causes uncontrolled bleeding, loss of blood clots, and bacterial infection, leading to the dry socket and bone resorption. Thus, it is highly attractive to design a bio-multifunctional scaffold with outstanding antimicrobial, hemostatic, and osteogenic performances for avoiding dry sockets in clinical applications. Herein, alginate (AG)/quaternized chitosan (Qch)/diatomite (Di) sponges were fabricated via electrostatic interaction, Ca cross-linking, as well as lyophilization methods.

Effects of Amino Hyperbranched Polymer-Modified Carbon Nanotubes on the Crystallization Behavior of Poly (-Lactic Acid) (PLLA).

Poly--lactic acid (PLLA) is an environmentally friendly and renewable polymer material with excellent prospects, but its low crystallization rate greatly limits its application. Through the amidation reaction between amino hyperbranched polymer (HBP N103) and carboxylated carbon nanotubes (CNTs), CNTs-N103 was obtained. The modification was confirmed by Fourier-transform infrared (FTIR) spectroscopy, X-ray electron spectroscopy (XPS) and thermogravimetric analysis (TGA).

Chitosan-CaP microflowers and metronidazole loaded calcium alginate sponges with enhanced antibacterial, hemostatic and osteogenic properties for the prevention of dry socket after tooth removal.

Tooth removal, particularly for patients with severe periodontitis, can frequently cause massive bleeding, postoperative infection, and bone resorption, resulting in a dry socket. Thus, developing bio-multifunctional materials with excellent antibacterial, hemostatic, and osteogenic characteristics for the prevention of dry sockets after tooth removal is highly desirable in clinical applications. Herein, chitosan-CaP microflowers (CM) and metronidazole (MD) loaded calcium alginate (CA) sponges (CA@CM/MD) with enhanced antibacterial, hemostatic, and osteogenic properties were developed via Ca crosslinking, lyophilization, and electrostatic interaction for the prevention of dry socket after tooth removal.

High-density lipoprotein reduces microglia activation and protects against experimental autoimmune encephalomyelitis in mice.

Studies have shown that high-density lipoprotein (HDL) is a powerful anti-atherosclerosis factor in vivo and in vitro, with anti-inflammatory effects, and it also plays an important role in the immune system and central nervous system (CNS). In this study, the BV2 microglia inflammation model and experimental autoimmune encephalomyelitis animal model were used to investigate the potential mechanism of HDL in multiple sclerosis. Our results show that HDL inhibits the activation of BV2 microglia in a model of BV2 microglia inflammation and were validated with primary microglia.

Tongue lipoma in an older male: A case report and literature review of patients with tongue lipoma reported in China.

Lipoma is the most common benign tumor that occurs at any region where adipose tissue is present. However, as the tongue is devoid of adipocyte it is an extremely rare site for a lipoma to develop, particularly in China. The present study reports the presence of a tongue lipoma in a 78-year-old man that measured 2.

Co-culture with periodontal ligament stem cells enhanced osteoblastic differentiation of MC3T3-E1 cells and osteoclastic differentiation of RAW264.7 cells.

Objectives: Periodontal ligament stem cells (PDLSCs) are characterized by having multipotential differentiation and immunoregulatory properties, which are the main mechanisms of PDLSCs-mediated periodontal regeneration. Periodontal or bone regeneration requires coordination of osteoblast and osteoclast, however, very little is known about the interactions between PDLSCs and osteoblast-like cells or osteoclast precursors. In this study, the indirect co-culture approach was introduced to preliminarily elucidate the effects of PDLSCs on differentiation of osteoblast-like cells and osteoclast precursors in vitro.

Adenosine 5'-monophosphate-induced hypothermia inhibits the activation of ERK1/2, JNK, p38 and NF-κB in endotoxemic rats.

Many studies have shown that LPS mainly activates four signal transduction pathways to induce inflammation, namely the p38, ERK1/2, JNK and IKK/NF-κB pathways. Studies have demonstrated that 5'-AMP-induced hypothermia (AIH) exhibits high anti-inflammatory capabilities. In this study, we explore that how AIH inhibits the inflammatory response.
