Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that certain of the immunohistochemical data shown in Fig. 1A on p. 5, colony formation data shown in Figs. 2C, H and M and 6D on p. 6 and p. 10 respectively, the western blots in Fig. 2B, Transwell cell migration and invasion assay data in Fig. 3B, D and F, and immunofluorescence data in Fig. 4C had already appeared in previously published articles written by different authors at different research institutes (some of which have subsequently been retracted)...

Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that the western blotting data shown in Fig. 4B and the Transwell cell invasion data shown in Figs. 2D and 4E were strikingly similar to data appearing in different form in other articles written by different authors at different research institutes that had already been published elsewhere prior to the submission of this paper to Molecular Medicine Reports (one of which has been retracted). Moreover, there appeared to be inappropriately edited western blot bands featured in Figs...

Following the publication of the above article, an interested reader drew to the authors' attention that the β‑actin control blots featured in Figs. 5A and 6A appeared to be strikingly similar. Upon examining their original data, the authors have realized that the β‑actin blots for Fig. 5A were inadvertently chosen incorrectly. The corrected version of Fig. 5 is shown opposite. Note that the error made in uploading the incorrect version of this figure did not affect the overall conclusions reported in the paper...

Following the publication of the above article, an interested reader drew to the authors' attention that, for the cell invasion assay experiments shown in Fig. 2D on p. 5, there appeared to be an overlapping section of data comparing between the Sao‑2/Control and MG‑63/siH19 panels, such that these data had been derived from the same original source where the panels were intended to portray the results from differently performed epxeriments. Upon examining their original data, the authors have realized that, in Fig...

BACKGROUND: Surgical trials are recognised as inherently challenging. Pilot and feasibility studies (PAFS) are increasingly acknowledged as a key method to optimise the design and conduct of randomised trials but remain limited in surgery. We used a mixed methods approach to develop recommendations for how surgical PAFS could be optimised. METHODS: The findings from a quantitative analysis of funded surgical PAFS over a 10-year period and in-depth qualitative interviews with surgeons, methodologists and funders were triangulated and synthesised with available methodological guidance on PAFS...

INTRODUCTION: Research is key to academic advancement in plastic surgery. However, access to publication opportunities may be inequitable as seen in other fields. We compared authorship trends of plastic surgery manuscripts that underwent single-blinded review (SBR) versus double-blinded review (DBR) to identify potential disparities in publication opportunities. METHODS: Publications from two plastic surgery journals using SBR and two using DBR from September 2019 to September 2021 were evaluated...

The author's in vitro analysis results were compared with those of an in silico structure analysis of the relevant sequences obtained from the author's entire genome sequence data. It was speculated that the in silico results together with author's phylogenetic results demonstrate problems in the authors' published in vitro data, which were presumably due to an inadequate accuracy of an in vitro assay. It was fortuitously suggested that alignment images to an excess repeat structure of the same locus provide a improved speculation of a number of repeats and that accurate in vitro assays are expected to complementarily provide reliable insights in the era of whole genome sequencing...

CRISPR-Cas systems have proven effective in a variety of applications due to their ease of use and relatively high editing efficiency. Yet, any individual CRISPR-Cas system has inherent limitations, necessitating a diversity of RNA-guided nucleases to suit applications with distinct needs. We searched through metagenomic sequences to identify RNA-guided nucleases and found enzymes from diverse CRISPR-Cas types and subtypes, the most promising of which we developed into gene-editing platforms. Based on prior annotations of the metagenomic sequences, we establish the likely taxa and sampling locations where Class 2 CRISPR-Cas systems active in eukaryotes may be found...

A feature issue is being presented by a team of guest editors containing papers based on contributed submissions including studies presented at Optics and the Brain, held April 24-27, 2023 as part of Optica Biophotonics Congress: Optics in the Life Sciences, in Vancouver, Canada.

This study aimed to identify opportunistic infections among human immunodeficiency virus (HIV) infected patients in Turkey. Therefore, we conducted a systematic literature review of the studies published up to October 1, 2022, in the Pubmed, Web of Science (WoS), and ULAKBİM TR Dizin databases. We searched for medical subject headings (MeSH) terms of (HIV) OR (AIDS) OR (human immunodeficiency virus) AND (opportunistic infections) AND (Turkey). Fifty-five studies in Pubmed, 68 in WoS, and 212 in ULAKBİM TR Dizin were listed with these keywords...
