Self-Healing and Injectable Hydrogel for Matching Skin Flap Regeneration.

The fabrication of highly biocompatible hydrogels with multiple unique healing abilities for the whole healing process, for example, multifunctional hydrogels with injectable, degradation, antibacterial, antihypoxic, and wound healing-promoting properties that match the dynamic healing process of skin flap regeneration, is currently a research challenge. Here, a multifunctional and dynamic coordinative polyethylene glycol (PEG) hydrogel with mangiferin liposomes (MF-Lip@PEG) is developed for clinical applications through Ag-S coordination of four-arm-PEG-SH and Ag. Compared to MF-PEG, MF-Lip@PEG exhibits self-healing properties, lower swelling percentages, and a longer endurance period.

Discordance of pathological thin melanoma thickness and T stage in SEER registry: impacts on clinical management and research directions.

Background: Ultrathin melanoma was previously demonstrated to have higher risk for melanoma-specific mortality using SEER database. However, these guideline-changing conclusions has been recently challenged by miscoding of thickness. This present study was performed to assess the prognosis of thin and ultrathin melanoma using only surgically-treated, pathologically confirmed and after removal of discordant cases.

Activation of TRPV4 Increases Neovascularization of Rat Prefabricated Flaps.

Background:  Inadequate neovascularization is a major risk factor that can lead to subsequent necrosis of prefabricated flaps. Recent evidence indicates that transient receptor potential cation channel, subfamily V, member 4 (TRPV4) activates growth and remodeling of collateral arteries in ischemia tissues by responding to elevated fluid shear stress (FSS). Therefore, we evaluated whether TRPV4 could increase neovascularization in prefabricated flaps in a rat model.

A murine model of orthotopic periorbital subunit transplantation.

Background: Conventional reconstructive methods fail to achieve satisfactory results in total eyelid defect cases. Vascularized composite tissue allotransplantation might provide both good appearance and function for these patients. We developed an orthotopic periorbital transplantation model in rats to facilitate further experimentation in this field.

Fabrication of New Thermo-pH Responsive Carbon Nanotube Gels.

Stimuli-responsive gels have widespread attraction due to their potential applications. In this work, we have demonstrated the preparation of new multiwall carbon nanotube (MWNT) incorporate multi-responsive (pH and thermal) gels (MWNT-IPN-MRG) though network formation with functional macromolecules that interact each other via hydrogen bonds, covalent networking and temporary associative forces. A simple strategy has been developed to prepare MWNT-IPN-MRG.

Efficacy and Safety of Cell-Assisted Lipotransfer: A Systematic Review and Meta-Analysis.

Background: The main drawback of autologous fat grafting, which is commonly used for soft-tissue augmentation, is the high resorption rate. Cell-assisted lipotransfer has been used to improve fat graft survival; however, evidence for its efficacy and safety is still lacking.

Methods: The authors searched PubMed, Cochrane Library, EBSCO, and EMBASE for clinical studies on cell-assisted lipotransfer published from 2008 through 2014.
