BACKGROUND:  Submucosal tunneling endoscopic resection (STER) has emerged as a feasible technique for resecting upper gastrointestinal (GI) tract submucosal tumors (SMTs) through natural orifice transluminal endoscopic surgery. STER reduces the risk of postoperative perforation and abdominal infections and promotes rapid wound healing. The aim of this meta-analysis was to evaluate the safety and efficacy of STER for small (≤ 3.5 cm) upper GI SMTs and explore the potential factors influencing STER's efficacy and complication rate...

Purpose: Optic nerve crush (ONC) induces retinal ganglion cell (RGC) death, which causes vision loss in glaucoma. To investigate early events leading to apoptosis of RGCs, we performed gene expression analysis of injured retinas in the period before RGC loss. Methods: The temporal changes of gene profiles at 0, 1, and 4 days after ONC were determined by DNA microarray. To verify the gene expression changes in RGCs, we enriched RGCs by laser-captured microdissection and performed real-time RT-PCR of 14 selected genes...

BACKGROUND/AIMS: Higher level of serum uric acid (SUA) predicts early entry to dialysis in chronic kidney disease (CKD) patients. However, a short-term effect of SUA remains to be elucidated using a novel surrogate endpoint. METHODS: Japanese CKD stage 3 to 4 patients were retrospectively examined (n= 701). The follow-up level of SUA was estimated as time-averaged uric acid (TA-UA). A propensity score for 6.0, 6.5 or 7.0 mg/dL of TA-UA was respectively calculated using baseline 23 covariates...

Local invasion of adjacent viscera by colorectal liver metastases (CRLM) is no longer considered an absolute contraindication to curative hepatic resection. A growing number of observational analyses have illustrated the feasibility of such resections; however, the evidence base is at best heterogeneous with a lack of evidence comparing similar patient groups. We aimed to evaluate the outcomes of hepatectomy for CRLM when combined with other viscera and compare to a matched cohort of isolated hepatic resections...

Recent studies have established important roles of de novo mutations (DNMs) in autism spectrum disorders (ASDs). Here, we analyze DNMs in 262 ASD probands of Japanese origin and confirm the "de novo paradigm" of ASDs across ethnicities. Based on this consistency, we combine the lists of damaging DNMs in our and published ASD cohorts (total number of trios, 4,244) and perform integrative bioinformatics analyses. Besides replicating the findings of previous studies, our analyses highlight ATP-binding genes and fetal cerebellar/striatal circuits...

Jingjing Zhao, Zheng You
High-speed and accurate cell sorting is of great significance for cell analysis regarding both bioresearch and clinical application. Different from the jet-in-air sorting of commercial flow cytometers, sorting in fully enclosed and disposal microfluidic chips can avoid aerosols and crosscontamination, thus contributing to the improvement of biosafety and test accuracy. However, current microfluidic sorters usually require complicated structures, or otherwise cannot attain high throughput. In this article, a sorting mechanism for microfluidics is proposed for the first time based on the jet flow induced by the spark-generated cavitation microbubble that can be easily realized by a pair of electrodes...

Material activation assessment of a proposed accelerator-based boron neutron capture therapy facility was performed using the FLUKA Monte Carlo code to quantify the magnitude of the problem in terms of the isotope inventories, induced activities, and residual dose rates. Two simplified operation scenarios were considered: a 30-min proton bombardment to simulate a typical session of patient treatment and a long-term 1 year continuous operation to estimate the accumulation of long-lived radionuclides. Following the generation and transport of decay radiation, the space- and time-dependent inventories of induced radionuclides in materials and residual dose rates after shutdown were obtained...

Family- and population-based genetic studies have successfully identified multiple disease-susceptibility loci for Age-related Macular Degeneration (AMD), one of the first batch and most successful examples of genome-wide association study (GWAS). However, most genetic studies to date have focused on case-control studies of late AMD (choroidal neovascularization [CNV] or geographic atrophy [GA]). The genetic influences on disease progression are largely unexplored. We assembled unique resources to perform a genome-wide bivariate time-to-event analysis to test for association of time-to-late-AMD with ∼9 million variants on 2,721 Caucasians from a large multi-center randomized clinical trial, the Age-Related Eye Disease Study...

Plasmids are mobile genetics elements that play an important role in the environmental adaptation of microorganisms. Although plasmids are usually analyzed in cultured microorganisms, there is a need for methods that allow for the analysis of pools of plasmids (plasmidomes) in environmental samples. To that end, several molecular biology and bioinformatics methods have been developed; however, they are limited to environments with low diversity and cannot recover large plasmids. Here, we present PlasFlow, a novel tool based on genomic signatures that employs a neural network approach for identification of bacterial plasmid sequences in environmental samples...

OBJECTIVES: Prerequisites for successful trachea transplantation include the use of a biocompatible construct, submucosal vascularization and an epithelial covering. Implantation of non-epithelialized tracheal scaffolds may lead to stenosis. However, epithelial grafting or seeding can only be attempted onto a well-vascularized submucosal bed. Our aim was to investigate a method to prevent stenosis during prelamination of non-epithelialized, gently decellularized rabbit tracheae and to evaluate whether grafting of revascularized constructs with buccal mucosa is feasible...
