The eradication rates for Helicobacter pylori have decreased in Korea although the prevalence of this bacterium has also decreased. Antibiotic resistance is likely to be a crucial factor H. success, and we therefore mapped these patterns nationwide Korea.Five hundred ninety adult subjects were prospectively enrolled from 2017 2018 15 centers across six geographic areas Korea. A total 580 biopsy tissues had been sampled patients during an upper endoscopy frozen at -80°C delivered central...
Broadband detection of mid-infrared (IR) photons extends to advanced optoelectronic applications such as imaging, sensing, and telecommunications. While graphene offers an attractive platform for broadband visible/IR photodetection, previous efforts improve its responsivity, example, by integrating light-absorbing colloids or waveguide antenna fabrication, were achieved at the cost reduced photon bandwidth. In this work, we demonstrate room-temperature operation a novel mid-IR photodetector...
Gastric cancer (GC) is a leading cause of cancer-related mortality. Although microbes besides Helicobacter pylori may also contribute to gastric carcinogenesis, wild-type germ-free (GF) mouse models investigating the role human microbiota in process are not yet available. We aimed evaluate histopathological features GF stomachs transplanted with from patients different disease states and their relationships microbiota.Microbiota profiles corpus antrum tissues fluid 12 dysplasia or GC were...
Phosphoinositide-specific phospholipase C (PLC) plays a pivotal role in the signal transduction of various cellular responses. However, although it is undeniably important that modulators PLC activity be identified, no direct modulator has been identified until now. In this study, by screening more than 10,000 different compounds human neutrophils, we compound strongly enhances superoxide-generating activity, which well known to PLC-dependent. The active...
Several studies have reported controversial results about clinicopathological features and prognoses in gastric cancer patients with respect to age, partly due variable definitions of young age inhomogeneity the patient population. The aim study was analyze prognostic value all stages a large consecutive series.Between 2000 2005, 3,362 were enrolled database. Patients divided into three groups: group 1 (< or =45), 2 (46-70), 3 (> =71).Upper location linitis plastica more frequent 1. Young...

Modulating light via coherent charge oscillations in solids is the subject of intense research topics opto-plasmonics. Although a variety methods are proposed to increase such modulation efficiency, one central challenge achieve high depth (defined by ratio extinction with/without light) under small photon-flux injection, which becomes fundamental trade-off issue both metals and semiconductors. Here, fabricating simple micro-ribbon arrays topological insulator Bi2Se3, we report an...
Abstract The 1 s exciton—the ground state of a bound electron-hole pair—is central to understanding the photoresponse monolayer transition metal dichalcogenides. Above exciton, recent visible and near-infrared investigations have revealed that excited excitons are much richer, exhibiting series Rydberg-like states. A natural question is then how internal excitonic transitions interrelated on photoexcitation. Accessing these intraexcitonic transitions, however, demands fundamentally different...
At the end of tether: Aryl hydrazides that have carbonyl groups tethered at para position aromatic ring undergo an intramolecular Fischer indolization reaction to give corresponding indolophanes. Strategic insertion a double bond in tether enables tandem [3,3] sigmatropic rearrangement occur tricyclic benzo[cd]indoles.
