BACKGROUND/AIMS Endoscopic treatment has been broadly applied to superficial esophageal neoplasms. Endoscopic submucosal dissection (ESD) allows for high rates of en bloc resection, precise histological assessment, and low rates of local recurrence. The aim of this study was to evaluate the outcomes of ESD for superficial esophageal neoplasms. METHODS We retrospectively reviewed 36 esophageal...

Desorption/ionization on silicon mass spectrometry (DIOS-MS) is demonstrated as a quantitative analytical tool when coupled to electrospray deposition (ESD). In this study, we illustrate the utility of DIOS-MS in the quantitative analysis of a peptide and two amino acids with deuterated and structural analogues used as internal standards. An important feature of this approach is the incorporati...

A V-band low-noise amplifier (LNA) with electrostatic discharge (ESD) protection using RF junction varactors is demonstrated in a 65-nm CMOS technology. The gate-source junction varactor is used to achieve a power-constrained simultaneous noise and input matching, and also as an auxiliary ESD protection for the NS and ND modes. The measured results shows an over 2.0-kV ESD protection in the PD ...

Radiofrequency ablation (RFA) and endoscopic submucosal dissection (ESD) can potentially be applied for early esophageal squamous cell neoplasia (ESCN); however, no study has directly compared these 2 modalities.We retrospectively enrolled the patients with flat-type "large" (length ≥3 cm extending ≥1/2 of the circumference of esophagus) early ESCNs treated endoscopically. The main outcome meas...

Current standard test methods for the evaluation of the performance of modern ESDprotective clothing used in electronics industry do not measure correctly the effectiveness of the clothing to protect sensitive electronics from electrostatic phenomena. Therefore a new European research project – ESTAT-Garments – was started in early 2002. The main objective of this three-years project (2002-2005...

−Failure analysis is fundamental to the design and development methodology of electrostatic discharge (ESD) devices and ESD robust circuits. The role of failure analysis (FA) in the models, methodology, band mechanisms evaluation for improving ESD robustness of semiconductor products in CMOS, silicon-on-insulator (SOI) and silicon germanium (SiGe) technologies will be reviewed. Index Terms−Reli...

Electrostatic Discharge (ESD) is generally recognized as an increasingly important issue for modern integrated circuits. Thinner gate oxides, complex chips with multiple power supplies and/or mixed-signal blocks, larger chip capacitance and faster circuit operation all contribute to increased ESD-sensitivity of advanced semiconductor products [1]. Detailed understanding of complex circuit-devic...

Background and study aims  Proper sedation is necessary for the safe and satisfactory completion of endoscopic submucosal dissection (ESD) for early gastric cancer. This study was conducted as a comparative trial of efficacy and safety, comparing propofol-based sedation and midazolam-based sedation during ESD of early gastric cancer patients. Patients and methods  This study examined 64 lesio...

has recently been developed for endo− scopic treatment of gastrointestinal tu− mors, enabling en bloc resection of even large tumors [1,2]. Although many en− doscopists now perform ESD for early− stage gastric cancer, ESD has yet to be es− tablished as a safe therapy for colonic dis− eases, even in Japan. It is still unclear whether ESD is indicated for submucosal tumors (SMTs), and ESD for col...

Background and study aims  Endoscopic submucosal dissection (ESD) is useful for en bloc resection of superficial colorectal neoplasms to ensure accurate histologic diagnoses. However, colorectal ESD is associated with a high frequency of adverse events (AEs). We aimed to investigate the effectiveness of prophylactic clip closure (PCC) of mucosal defects for AEs after colorectal ESD. Patients ...
