With this external quality assessment (EQA) scheme, we aim to investigate the diagnostic performance of the currently available methods for the detection of ALK alterations in non-small cell lung cancer on a national scale, namely, in situ hybridization (ISH), immunohistochemistry (IHC), and RNA/DNA sequencing (NGS). The EQA scheme cohort consisted of ten specimens, including four ALK positive and six ALK negative samples, which were thoroughly pretested using IHC, ISH, and RNA/DNA NGS. Unstained tumor sections were provided to the 57 participants, and the results were retrieved via an online questionnaire. ISH was used by 29, IHC by 38, and RNA/DNA sequencing by 19 participants. Twenty-eight institutions (97%) passed the ring trial using ISH, 33 (87%) by using IHC, and 18 (95%) by using NGS. The highest sensitivity and interrater agreement (Fleiss ' kappa) was observed for RNA/DNA sequencing (99%, 0.975), followed by ISH (94%, 0.898) and IHC (92%, 0.888). Autophinib inhibitor However, the proportion of samples that were not evaluable due to bad tissue quality was also higher for RNA/DNA sequencing (4%) compared with ISH (0.7%) and IHC (0.5%). While all three methods produced reliable results between the different institutions, the highest sensitivity and concordance were observed for RNA/DNA sequencing. These findings encourage the broad implementation of this method in routine diagnostic, although the application might be limited by technical capacity, economical restrictions, and tissue quality of formalin-fixed samples.The Up-and-Coming-Scientist section of the current issue of the Journal of Membrane Biology features the invited essay by Dr. Mercedes Alfonso-Prieto, Assistant Professor at the Forschungszentrum Jülich (FZJ), Germany, and the Heinrich-Heine University Düsseldorf, Vogt Institute for Brain Research. Dr. Alfonso-Prieto completed her doctoral degree in chemistry at the Barcelona Science Park, Spain, in 2009, pursued post-doctoral research in computational molecular sciences at Temple University, USA, and then, as a Marie Curie post-doctoral fellow at the University of Barcelona, worked on computations of enzyme reactions and modeling of photoswitchable ligands targeting neuronal receptors. In 2016, she joined the Institute for Advanced Science and the Institute for Computational Biomedicine at the FZJ, where she pursues research on modeling and simulation of chemical senses. The invited essay by Dr. Alfonso-Prieto discusses state-of-the-art modeling of molecular receptors involved in chemical sensing - the senses of taste and smell. These receptors, and computational methods to study them, are the focus of Dr. Alfonso-Prieto's research. Recently, Dr. Alfonso-Prieto and colleagues have presented a new methodology to predict ligand binding poses for GPCRs, and extensive computations that deciphered the ligand selectivity determinants of bitter taste receptors. These developments inform our current understanding of how taste occurs at the molecular level.The extracellular space in plants, termed the apoplast, has a pH and sugar content that enables bacterial growth and represents a possible niche for the establishment of endophytic bacteria. Previous studies have investigated the effects of diazotrophic bacteria inoculation in sugarcane varieties, but it has not yet been analyzed how the microbial community of apoplast fluid of sugarcane is affected. High-throughput next generation sequencing of the 16S rRNA gene was used throughout this study to determine the effect of inoculation with a diazotrophic bacteria consortium, previously isolated from sugarcane, on the native bacterial population of sugarcane variety RB867515 grown in the field. The analyses were carried out 450 days after inoculation. The results revealed the presence of 22 phyla, with predominance of Proteobacteria phylum. It was observed that the inoculated consortium changed the indigenous bacterial community structure of sugarcane apoplast fluid by decreasing diversity and evenness, interfering in the composition of rare species. Microbial community composition analysis revealed differences between treatments. The differential abundance test showed there were 43 amplicon sequence variants (ASVs) which were relatively more abundant in the inoculated treatment, with predominance of the Sphingomonas genus. The predicted functions of the most abundant ASVs revealed the presence of genera related to plant growth promotion and protection against phytopathogens. Analysis to evaluate the occurrence of inoculated strains in the recovered data was not conclusive since the ASVs taxonomically close to the inoculated bacteria were observed in low abundance. The present study is the first report to elucidate the bacterial community in sugarcane apoplast fluid using a culture-independent approach. It demonstrated that the diazotrophic bacterial consortium interferes in the natural bacterial community in sugarcane variety RB867515.

To evaluate the outcomes of Ilizarov external fixator (IEF) and minimal invasive surgery (MIS) in correction of neglected club foot (NCF).

Thirty-seven feet in 24 child, between five and 15years old were diagnosed as NCF. All were treated with Achilles tendon lengthening (ATL) and IEF for gradual correction. After IEF removal, cast was applied for six weeks to maintain correction of the deformity.

There were 20 boys and four girls. Seven children had left (Lt), four children had right (Rt) while 13 children had bilateral foot deformity. The mean age at surgery was 10.3 (range 5-15) years with an average follow-up of 32.5 (range 24-96) months. All feet were graded as severe according to Pirani score. All feet were corrected after an average six weeks in IEF. After twoyears follow-up, 23 feet (16 patients) showed good results, five feet (3 patients) showed fair results and four feet (2 patients) had Rt side foot fair result while the Lt foot had good result in both patients. Five feet (3 patients) showed poor results. Eight patients had pin site infection. One case had infected skin and subcutaneous tissue and needed debridement. Two cases developed skin sloughing, changes in color and needed close follow-up.

We recommend combined IEF and MIS as a suitable, efficient and successful salvage procedure in the management of severe idiopathic NCF in children especially in developing countries.

It is of obvious interest to identify clinical prognosis-related oncogenes in HNSCC (head and neck squamous cell carcinoma).

Based on the available datasets within the TCGA (The Cancer Genome Atlas) and the GEO (Gene Expression Omnibus) databases, the potential mechanism of action of the SEC61G (SEC61 translocon subunit gamma) gene in HNSCC tumorigenesis was explored by several bioinformatics approaches.

There was a higher expression level of SEC61G in primary HNSCC tumor tissues than in normal tissues. Moreover, highly expressed SEC61G was statistically associated with the poor survival prognosis of HNSCC patients. When HPV (human papilloma virus) was considered, we also observed a relatively lower proportion of "arm-level gain" and "high amplification" types of CNA (copy-number alteration) in the HNSCC-HPV (+) group than in the HNSCC-HPV (-) group. Additionally, we identified SEC61G CAN-correlated genes, such as CCT6A (chaperonin-containing TCP1 subunit 6A) and HUS1 (HUS1 checkpoint clamp component), and found a correlation between SEC61G copy-number segments and prognosis related to overall and progression-free survival intervals of HNSCC patients. Moreover, the molecular regulation mechanisms of the spliceosome, ribosome, proteasome degradation, cell adhesion, and immune infiltration of B and CD8

T cells may contribute to the involvement of SEC61G in the pathogenesis of HNSCC.

The SEC61G gene was identified for the first time as a prognostic biomarker of HNSCC. The detailed underlying mechanism merits further research.

Monogenic forms of PDB and PDB-related phenotypes as well as genome-wide association studies strongly support the involvement of genetic variation in components of the NF-κB signaling pathway in the pathogenesis of PDB. In this study, we performed a panel-based mutation screening of 52 genes. Single variant association testing and a series of gene-based association tests were performed. The former revealed a novel association with NFKBIA and further supports an involvement of variation in NR4A1, VCP, TNFRSF11A, and NUP205. The latter indicated a trend for enrichment of rare genetic variation in GAB2 and PRKCI. Both single variant tests and gene-based tests highlighted two genes, NR4A1 and NUP205. In conclusion, our findings support the involvement of genetic variation in modulators of NF-κB signaling in PDB and confirm the association of previously associated genes with the pathogenesis of PDB.Osteogenesis imperfecta type XI (OI-XI) and Bruck syndrome type I (BS1) are two rare disorders caused by biallelic variants in the FKBP10, characterized by early-onset bone fractures and progressive skeletal deformities. The patients with OI-XI, also co-segregated with autosomal-recessive epidermolysis bullosa simplex caused by KRT14 variant, have been reported. In this study, the follow-up clinical features of the patients with OI-XI and BS1 phenotypes due to biallelic FKBP10 variants are compared. The aim of this study is to investigate the follow-up findings of OI-XI and BS1 phenotypes in patients with the FKBP10 variants. A total of 19 children, ten males and nine females, from 16 unrelated families were included in the study. FKBP10 variants were investigated by next-generation sequencing (NGS) based panel gene test or Sanger sequencing. Seventeen patients were followed between 1.5 and 16.8 years, and the last follow-up age was between 2 and 24.6 years (median 10.7 years). They received intravenous bisphhile others were not ambulatory, and they used wheelchairs for mobility. We identified two novel variants in FKBP10. Families originating from the same geographic region and having the same variant suggest founder effects. Although the number of fractures decreased with bisphosphonate treatment, none of our patients were able to walk during the follow-up. This study is valuable in terms of showing the follow-up findings of patients with FKBP10 variants for the first time.The coming of the Last Universal Cellular Ancestor (LUCA) was the singular watershed event in the making of the biotic world. If the coming of LUCA marked the crossing of the "Darwinian Threshold", then pre-LUCA evolution must have been Pre-Darwinian and at least partly non-Darwinian. But how did Pre-Darwinian evolution before LUCA actually operate? I broaden our understanding of the central mechanism of biological evolution (i.e., variation-selection-inheritance) and then extend this broadened understanding to its natural starting point the origin(s) of the First Universal Cellular Ancestors (FUCAs) before LUCA. My hypothesis centers upon vesicles' making-and-remaking as variation and competition as selection. More specifically, I argue that vesicles' acquisition and merger, via breaking-and-repacking, proto-endocytosis, proto-endosymbiosis, and other similar processes had been a central force of both variation and selection in the pre-Darwinian epoch. These new perspectives shed important new light upon the origin of FUCAs and their subsequent evolution into LUCA.
