Abstract
The article entitled, "lncRNA IGF2-AS Promotes Cell Proliferation, Migration, and Invasion of Gastric Cancer by Modulating miR-937/EZH2 Axis," by Zizi Li, Zhanyu Li, Zhijuan Zhong, Jianhui Zhou, Shenhao Huang, Wenying Zhou, and Jianfeng Xu (Cancer Biother Radiopharm epub 25 May 2020; Doi: 10.1089/cbr.2019.3275) is being officially retracted from the literature. The Editor-in-Chief of Cancer Biotherapy and Radiopharmaceuticals (CBR) received an email from the corresponding author of the article, Wenying Zhou, on September 7, 2020, indicating: "…this manuscript should no longer be published [because of] information from our superior and also after discussion with my research team, we want to repeat our experiment and then revise the [manuscript]. Our team has a lot of controversy about these results. In order to ensure the quality of the data and not to mislead readers, we decided to [retract] the manuscript. We will be more rigorous in our further study." The editor requested further information about precisely which data could not be reproduced, to which Dr. Wenying Zhou responded: "…we found that the results of Figure 4B and 4C, Figure 5A and 5B could not be repeated. Our repeated results of Figure 4B and 4C were as follow[s]: compared with miR-NC group, there was no significant decrease of the luciferase activity in miR-937 group when cells co-transfected with EZH2 3'-UTR-WT. Our repeated results of Figure 5A and 5B were as follow[s]: miR-937 inhibited the proliferation of MNK-28 and SGC-7901 cells, but the cell proliferation had no significant change in miR-937+EZH2 group compared with miR-937+pcDNA group. These findings resulted in the uncertainty of the targeted relationship between miR-937 and EZH2. We also repeated these experiments in different environments, but they all contradict the results in the original data. So, the conclusion is very controversial. In a responsible attitude to the readers, we decide to [retract] the manuscript." The authors have extended their apologies to the Editor and to the readers of CBR. Though in the author's original email, the request was made to "withdraw" the paper, CBR has decided to fully retract it due to irreproducible data, as the journal is committed to preserving the scientific literature and the community it serves.

Abstract
Cancer is the main cause of death, so the search for active agents to be used in the therapy of this
disease, is necessary. According to studies conducted, substances derived from natural products have shown to
be promising in this endeavor. To these researches, one can associate with the aid of computational chemistry,
which is increasingly gaining popularity, due to the possibility of developing alternative strategies that could
help in choosing an appropriate set of compounds, avoiding unnecessary expenses with resources that would
generate unwanted substance. Thus, the objective of this study was to carry out an approach to several studies
that apply different methods of virtual screening to select natural products with potential anticancer activity.
This review presents reports of studies conducted with some natural products, such as coumarin, quinone, tannins,
alkaloids, flavonoids and terpenes.

Abstract
Background Planned re-laparotomies are a series of surgical interventions that are rarely used and have a high mortality rate. The aim of this study was to investigate the factors affecting mortality and the effectiveness of the use of the Bogota bag for temporary closure of the abdomen in patients for whom re-laparotomy was planned. Material/Methods A retrospective examination was made of data of patients in whom a Bogota bag was used in planned re-laparotomies for various reasons in the General Surgery Department of Suleyman Demirel University Medical Faculty between June 2008 and April 2014. Results Bogota bags were used in a total of 38 patients, comprising 23 (60.5%) males and 15 (39.5%) females, with a mean age of 58.94±17.89 years. The mean period of hospitalization was 14.5 days (range, 1–143 days) and the mean number of operations during that time was 3 (range, 1–11). The mean duration of intensive care unit stay was 6 days (range, 1–143 days). Malignancy was determined in 8 patients (21.1%). Indications were intra-abdominal sepsis in 23 patients (60.5%), mesenteric vascular disease in 10 patients (26.3%), and packing was required in 5 patients (13.2%). Mortality developed in 25 patients (65.8%). A significant relationship was determined between mortality and a diagnosis of mesenteric artery ischemia (p: 0.035). The mortality rate was 56% (n: 13) in patients diagnosed with intra-abdominal sepsis. A relationship was determined between mortality and age (p: 0.015), duration of hospital stay (p: 0.007), need for cardiac inotrope (p: 0.01), and need for mechanical ventilation (p: 0.01). The mean Apache II score was 26.4±5 for patients who died and 15.8±5.2 for surviving patients (p<0.001). In 5 (38.4%) of the 13 surviving patients, primary repair was applied to the abdomen, and in the remaining 8 patients abdominal wall repair was performed using dual mesh. Conclusions In patients in whom a Bogota bag was used, which is a cheap and easy method for temporary closure of the abdomen, the high mortality rates seen are related to diagnosis, Apache II score, age, and organ failure.
