Retraction "LncRNA AWPPH inhibits SMAD4 via EZH2 to regulate bladder cancer progression," by Feng Zhu, Xinjun Zhang, Qinnan Yu, Guangye Han, Fengxia Diao, Chunlei Wu, Yan Zhang, J Cell Biochem. 2018; 4496-4505 The above article, published online on 12 December 2017 in Wiley Online Library (https//onlinelibrary.wiley.com/doi/abs/10.1002/jcb.26556), has been retracted by agreement between the the journal's Editor in Chief, Prof. Dr. Christian Behl, and Wiley Periodicals LLC. The retraction has been agreed following an investigation based on allegations raised by a third party. Several flaws and inconsistencies between results presented and experimental methods described were found, the editors consider the conclusions of this article to be invalid. The authors collaborated in the investigation initially, but were not available for a final confirmation of the retraction.

Failed implant removal using a high-frequency electrosurgical device (HFED) has been reported to be less invasive than other surgical techniques. We sought to clarify the mechanism of removal torque reduction in an implant by heating with HFED.

Sixty-eight Wistar rats received titanium implants on the maxillary bone 4weeks after extraction of the first and second molars. The control group was sacrificed 6weeks after implant installation. In the experimental group, the implant was heated by HFED for 10s using three different power outputs, and samples were collected at 3, 7, and 14days after heating. Removal torque measurement and histological analysis were performed in the control and experimental groups. Implant surfaces were observed using an electron-probe microanalyzer (EPMA). Data were analyzed using Mann-Whitney U test at a significance level of 5%.

The removal torque could not be measured in the control group due to fracture of the implant. After heating, the removal torque was measurable without fracture and decreased significantly at 14days as compared with that at 3days (p<.05). Heating with "min" power output resulted in a significantly smaller blank lacunae area and fewer osteoclasts at 14days after heating (p<.05). EPMA revealed bone matrix adherence to outer surface of heated implant.

After heating, an enlarged area of blank lacunae around the implant and an increased number of osteoclasts into the bone marrow cavity were observed, which may have contributed to the reduction in removal torque.

The purpose of this paper is to present current knowledge about quality of life assessment in AA. The dermatology-specific Dermatology Life Quality Index (DLQI) was the most widely reported health-related quality of life instrument used in AA. Three AA-specific (Alopecia Areata Symptom Impact Scale, Alopecia Areata Quality of Life Index and Alopecia Areata Patients' Quality of Life) and three hair disease-specific instruments (Hairdex, Scalpdex and 'hair-specific Skindex-29') were identified with a range of content and validation characteristics there is little evidence yet of the actual use of these measures in AA. Scalpdex is the best-validated hair disease-specific instrument. Further extensive validation is needed for all of the AA-specific instruments. The European Academy of Dermatology and Venereology Task Force on Quality of Life and Patient Oriented Outcomes recommends the use of the dermatology-specific DLQI questionnaire, hair disease-specific Scalpdex and the alopecia areata-specific instruments the Alopecia Areata Symptom Impact Scale or Alopecia Areata Quality of Life Index, despite the limited experience of their use. Omilancor solubility dmso We hope that new treatment methods will be able to improve both clinical signs and health-related quality of life in patients with AA. In order to assess the outcomes of trials on these new treatment methods, it would be helpful when further development and validation of AA-specific instruments is being encouraged and also conducted.The Pd-catalyzed carbon-carbon bond formation pioneered by Heck in 1969 has dominated medicinal chemistry development for the ensuing fifty years. As the demand for more complex three-dimensional active pharmaceuticals continues to increase, preparative enzyme-mediated assembly, by virtue of its exquisite selectivity and sustainable nature, is poised to provide a practical and affordable alternative for accessing such compounds. In this minireview, we summarize recent state-of-the-art developments in practical enzyme-mediated assembly of carbocycles. When appropriate, background information on the enzymatic transformation is provided and challenges and/or limitations are also highlighted.Retraction "Notoginsenoside R1 protects WI-38 cells against lipopolysaccharide-triggered injury via adjusting the miR-181a/TLR4 axis," by Daolin Qian, Xiankun Shao, Yingchun Li, Xinyan Sun, J Cell Biochem. 2019; 19764-19774 The above article, published online on 11 July 2019 in Wiley Online Library (https//onlinelibrary.wiley.com/doi/abs/10.1002/jcb.29282), has been retracted by agreement between the the journal's Editor in Chief, Prof. Dr. Christian Behl, and Wiley Periodicals LLC.
