A Prospective Observational Study to Evaluate the Ability of Artificial Intelligence Navigation System to Recognize Blood Vessels in Submucosal Dissection

ABSTRACT: Interventions: After obtaining consent, colorectal endoscopic submucosal dissection (colorectal ESD) is performed according to the usual clinical path (4 days/3 nights) currently in operation at Showa University Northern Hospital. The scope and devices were PCF-H290TI (Olympus Co., Tokyo, Japan), disposable tip attachment (D-201-11304 [Olympus Co., Tokyo, Japan]), and Flush knife Ns 1.5mm (Fujinon Co., Saitama, Japan), exactly the same as those we usually use. The treating physician must be an endoscopist with expertise in ESD (more than 50 cases of upper gastrointestinal ESD and more than 20 cases of colorectal ESD). During ESD, the AI system is operated in real time, but the surgeon does not see the results but only records the output. Therefore, the ESD procedure itself is no different from the usual treatment, and the use of this system should have no impact. Primary outcome(s): Vessel recognition rate (percentage of frames in which vessels were identified with an IoU index of 0.5 or higher) Study Design: Single arm Non-randomized

Proteomics Analysis of Soybean Hypocotyl during Recovery after Flooding Stress

Project description:Soybean (Glycine max L. cv Enrei) seeds were sterilized with 2% sodium hypochlorite solution and then thoroughly rinsed in water. The sterilized seeds were sown 4 cm inside surface of sand in 450 mL of quartz seedling cases wetted with 150 mL water and grown at 25°C and 70% humidity in a growth chamber (Sanyo, Tokyo, Japan) under white fluorescent light (160 μmol m-2 s-1, 16 h light period/day). Two-day-old soybeans were flooded for 2 days and hypocotyl samples were collected at the day of removal of flooding and then at 2 more points during the 4-day recovery period.

Gonadal DNA methylomes of half-smooth tongue sole Cynoglossus semilaevis

Project description:Environmental sex determination (ESD) occurs in divergent, phylogenetically unrelated taxa, and in some species co-occurs with genetic sex determination (GSD) mechanisms. Although epigenetic regulation in response to environmental effects has long been proposed to be associated with ESD, a systemic analysis on epigenetic regulation of ESD is still lacking. Using half-smooth tongue sole (Cynoglossus semilaevis) as a model – a marine fish which has both ZW chromosomal GSD and temperature-dependent ESD – we investigated the role of DNA methylation in transition from GSD to ESD by comparing gonadal DNA methylomes of parental females, parental pseudo-males, F1 females, F1 pseudo-males and normal males.

Pimary human keratinocyte knockdown with deltaNp63 specific siRNA

Project description:Human ΔNp63-specific siRNA was obtained from Invitrogen (Carlsbad, CA; sense: 5′-ACAAUGCCCAGACUCAAUU-3′; antisense: 5′-AAUUGAGUCUGGGCAUUGU-3′). Scrambled sequence siRNA for the negative control was purchased from Invitrogen. Transfections were performed using Lipofectamine RNAiMAX (Invitrogen) in Opti-MEM (GIBCO) at 40 nmol/L according to the manufacturer's instructions. The culture medium was replaced at 6 h after siRNA transfection. mRNA was extracted from NHEKs transfected with ΔNp63-specific or scramble sequence siRNA at 72 h after transfection. Microarray slides were scanned using a 3D-GENE human 25k (TORAY, Tokyo, Japan) and microarray images were automatically analyzed with AROSTM, version 4.0 (Operon Biotechnologies, Tokyo, Japan).

Differential expression profile and diagnostic value of plasma exosomal circular RNA in hepatocellular carcinoma

Project description:Circular RNAs (circRNAs) are recently found to be promising kind of biomarkers for tumors. However, plasma exosomal circRNAs in the diagnosis of hepatocellular carcinoma (HCC) is largely unknown. In this study, we report the application of next-generation sequencing technology for high-throughput profiling of plasma exosome general transcriptome between 3 cases of hepatocellular carcinoma patients and 3 cases of healthy control. We obtained exosomes through ultrahigh-speed centrifugation techniques and verified exosomes through immunoblotting, NanoSight NS300(Malvern Panalytical, Malvern, UK) and JEM-1230 transmission electron microscope (TEM) (JEOL, Tokyo, Japan). And then, we find that there are 41 circRNAs that have differential expression. This study discovered the differences between hepatocellular carcinoma and healthy people preliminarily.

Expression data of hepatocellular carcinoma and adjacent liver tissues

Project description:To identify therapeutic targets with high specificity to HCC, we searched for genes significantly up-regulated in HCC over corresponding non-tumor liver using high-density microarrays Keywords: disease state analysis HCC and surrounding non-tumor liver tissue samples were collected from 10 cases who underwent liver resection for HCC at National Cancer Center Hospital (Tokyo, Japan). One µg of total RNA was converted to end-labeled cRNA using the Whole Transcript Sense Target Labeling kit (Affymetrix, Santa Clara, CA). The fluorescent cRNA probes were hybridized to Human Exon 1.0 ST arrays (Affymetrix), as instructed by the supplier.

Project description:Adult (6- to 8-week-old) C57BL/6 purchased from CLEA Japan Inc. (Tokyo, Japan) were used as donors ocular pigment epithelium (PE). To cultivate retinal PE (RPE) eyes were cut into two parts along a circumferential line posterior to the ciliary process, creating a ciliary body-deficient posterior eyecup. The eyecup was then incubated in 0.2% trypsin (Biowhitaker) for 1 hr. These tissues were triturated to make a single cell suspension, and then re-suspended in the medium. Keywords: Comparison

Temperature dependent sex determination in the turtle Trachemys scripta

Project description:Sex determination is the process by which and original bipotential gonad differentiate into either a testis or ovaries. While mammals and birds determine their sex solely by genetic clues (genetic sex determination, GSD), other vertebrates like the turtle Trachemys scripta are influenced by environmental factors, like temperature (environmental sex determination, ESD). In both cases an initially bipotential gonad develops into either testes or ovaries in response to GSD or ESD cues. In order to shed light into the differences and similarities between sex determination systems we performed single-cell RNA-seq on Trachemys scripta developing gonads during the sex determination window.
