We, the Editors and Publisher of the journal Artificial Cells, Nanomedicine, and Biotechnology, have retracted the following article: Gang Wang, Ping Wang, Xiaojun Yan & Jing Liu (2019) Neferine hinders choriocarcinoma cell proliferation, migration and invasion through repression of long noncoding RNA-CHRF, Artificial Cells, Nanomedicine, and Biotechnology, 47:1, 4089–4096, DOI: 10.1080/21691401.2019.1671429 Since publication, concerns have been raised about the integrity of the data in the article. When approached for an explanation, the authors have been...

Objective: To conduct a phase-II trial using a ranking and selection paradigm where multiple treatments are compared with limited sample size and the best is chosen for a subsequent efficacy trial versus placebo. This strategy can find an effective treatment faster than traditional strategy of conducting larger trials against placebo. Methods: Sixty amyotrophic lateral sclerosis (ALS) participants were randomized 1:1:1 to creatine 30 g/day (CRE), tamoxifen 40 mg/day (T40), or tamoxifen 80 mg/day (T80), with...

Background: Several cervical laminectomy techniques have been described. One commonly used method involves making bilateral trough laminotomies using either a Kerrison rongeur or a high speed burr, and then removing the lamina en-bloc. Alternatively, some surgeons prefer to thin the lamina with the burr, and then remove the lamina in a piecemeal fashion using Kerrison rongeurs. Some surgeons have warned against the potential risk of iatrogenic spinal cord injury from inserting the Kerrison footplate into...

Objective: To investigate the role of lncRNA ANRIL in the modulation of myocardial cell apoptosis in acute myocardial infarction (AMI). Methods: AMI mice model was established, and lncRNA ANRIL, IL-33 and ST2 expressions were detected by quantitative real-time polymerase chain reaction (qRT-PCR) or western blot. The apoptosis of myocardial cells was detected by TUNEL assay. RNA pull-down and RNA immunoprecipitation (RIP) assays were used to confirm the interaction between lncRNA ANRIL and USP17. Results: Compared...
