    TRPC5-induced autophagy promotes drug resistance in breast carcinoma via CaMKKβ/AMPKα/mTOR pathway.
    Sci Rep 2017 Jun 9;7(1):3158. Epub 2017 Jun 9.
    Wuxi School of Medicine, Jiangnan University, Wuxi, China.
    Adriamycin is a first-line chemotherapy agent against cancer, but the development of resistance has become a major problem. Although autophagy is considered to be an adaptive survival response in response to chemotherapy and may be associated with chemoresistance, its inducer and the underlying molecular mechanisms remain unclear. Here, we demonstrate that adriamycin up-regulates the both levels of TRPC5 and autophagy, and the increase in autophagy is mediated by TRPC5 in breast cancer cells. Read More

    Cost-effectiveness of Early Division of the Forehead Flap Pedicle.
    JAMA Facial Plast Surg 2017 Jun 1. Epub 2017 Jun 1.
    Division of Facial Plastic and Reconstructive Surgery, Department of Otolaryngology-Head and Neck Surgery, Stanford University School of Medicine, Stanford, California.
    Importance: The paramedian forehead flap is considered the gold standard procedure to optimally reconstruct major defects of the nose, but this procedure generally requires 2 stages, where the flap pedicle is divided 3 weeks following the initial surgery to ensure adequate revascularization of the flap from the surrounding recipient tissue bed, which can cost a patient time out of work or away from normal social habits. It has previously been shown that the pedicle may be safely divided after 2 weeks in select patients where revascularization from the recipient bed was confirmed using intraoperative laser fluorescence angiography to potentially save the patient time and money.

    Objective: To demonstrate the cost-effectiveness of takedown of the paramedian forehead flap pedicle after 2 weeks using angiography with indocyanine green (ICG). Read More
