We developed multiplex polymerase chain reaction (PCR) to detect aac(6 ')/aph(2 "), aph(3 ')-IIIa, and ant(4 ')-Ia, the genes encoding most clinically relevant amino-glycoside modifying enzymes (AME), simultaneously, methicillin resistant gene, mecA, in Staphylococcus species. Clinical isolates of 45 S. aureus 47 coagulase negative staphylococci (CNS) from tertiary university hospitals were tested by conventional susceptibility testing, using agar dilution method PCR. Of a total 92 isolates,...
The purpose of the course presented here is to introduce freshmen embedded systems using LEGO Mindstorms, under an ANSI-C programming environment. students build their own robots, make programs for them ANSI-C, and operate them. By creating these become more motivated, learning basic concepts how can be applied real world problems.
Tegoprazan is a novel, fast- and long-acting potassium-competitive acid blocker that suppresses gastric secretion, which could benefit patients with non-erosive reflux disease (NERD), type of gastroesophageal disease.To evaluate the efficacy safety profiles tegoprazan compared those placebo in Korean NERD.In this phase 3, double-blind, placebo-controlled, multicentre study, 324 NERD were randomised into three treatment groups: 50 mg, 100 mg placebo. These drugs provided once daily for 4...
Lego Company has made a programmable robot set named Mindstorms NXT(NXT). This comes with several types of sensors, motor, and brick. The NXT is provided visual programming environment. Novice programmer can easily make program for using this software based on National Instruments' LabVIEW. Also, Microsoft developed platform called Robotics Studio(MSRS) which aimed to support all robot. MSRS also provides environment Visual Programming Language(MVPL). Both are in user friendly interface...
Background and Aim: Low-volume polyethylene glycol with ascorbic acid (PEG-Asc) use is reported to be as safe effective traditional 4-L use. However, PEG-Asc produces bubbles, which cause problems during colonoscopy. Data on the effects of using antifoaming agents such simethicone are lacking. The aim this CONSORT-prospective, randomized, observer-blinded, controlled trial compare quality bowel preparation compliance between users plus users. Methods: Adult outpatients aged 18 80 years...

Intestinal mucositis is a commonly encountered complication of chemotherapy. However, there are few effective treatments or preventive methods. Ursodeoxycholic acid (UDCA) stabilizes cell membranes, acts as an antioxidant and inhibits apoptosis, thereby exerting cytoprotective effects. The aim the present study was to examine ability UDCA protecting against chemotherapy‑associated mucositis. Sprague‑Dawley rats were randomly assigned five groups: Control, vehicle + 5‑fluorouracil (5‑FU),...
Objective Non-variceal upper gastrointestinal bleeding (NVUGIB) in patients receiving oral anticoagulants (OACs) may be fatal; however, little is known about re-bleeding and all-cause mortality after successful hemostasis. We investigated the clinical characteristics risk factors for death hemostasis.Methods Patients OACs diagnosed with NVUGIB between 2007 2021 were enrolled. All incidents confirmed if definite tract was detected via esophagogastroduodenoscopy.Results A total of 132 NVUGIB....
Although the incidence and complications of peptic ulcer disease have declined, <i>Helicobacter pylori</i> infection nonsteroidal anti-inflammatory drug use remain key risk factors. Advances in proton pump inhibitors potassium-competitive acid blockers improved treatment outcomes. However, increasing antibiotic resistance has reduced efficacy standard therapies for <i>H. eradication, necessitating development new approaches such as novel combinations bismuth-based regimens....
Rapid and accurate diagnostic tools are essential for the timely recognition of Helicobacter pylori (
Gastric cancer (GC) is the fifth most common cause of cancer-related death worldwide. Early detection crucial for improving survival rates and treatment outcomes. However, accurate GC-specific biomarkers remain unknown. This study aimed to identify metabolic differences between intestinal metaplasia (IM) GC determine pathways involved in GC. A analysis IM tissue samples from 37 patients with was conducted using ultra-performance liquid chromatography tandem mass spectrometry. Overall, 665...

Early video capsule endoscopy (VCE) may provide a high diagnostic yield and improve clinical outcomes in patients with overt obscure gastrointestinal bleeding (OGIB); however, there is no practical recommendation for the ideal timing of VCE application OGIB. Therefore, this study investigated efficacy to assess OGIB respect application.We retrospectively enrolled who had undergone between April 2004 February 2014 at tertiary referral academic center. We included hemodynamically stable...
Background/Aims Small bowel malignancies often present a diagnostic challenge due to their relative rarity and nonspecific clinical symptoms. However, technical developments in endoscopic instruments, including video capsule endoscopy (VCE) enteroscopy, have allowed for the visualization of entire small bowel. This study aimed investigate clinicopathological features malignant tumors diagnosed by VCE double-balloon enteroscopy (DBE) single tertiary center. Methods We retrospectively analyzed...
A methanolic extract of Lindera obtusiloba (Lauraceae) stems significantly attenuated glutamate-induced oxidative stress in HT22 hippocampal cells. Two new secoisolariciresinol derivatives, characterized as 9,9′-O-di-(E)-feruloyl-meso-5,5′-dimethoxysecoisolariciresinol (1) and 9,9′-O-di-(E)-sinapinoyl-meso-5,5′-dimethoxysecoisolariciresinol (2), were isolated, along with the known compound 9,9′-O-di-(E)-feruloyl-meso-secoisolariciresinol (3), from L. stems. Compounds 1, 2, 3 showed...
Background/Aims: Endoscopic assistive devices have been developed to reduce the complexity and improve safety of surgeries involving use endoscopes.We an robotic arm for endoscopic submucosal dissection (ESD) evaluated its efficiency in this vitro pilot study.Methods: ESD was performed using auxiliary transluminal robot.An test bed replicating intra-abdominal environment pig stomachs were used experiment.Participants divided into skilled operators unskilled operators.Each group 10 times by...
Sustainable agriculture in the era of climate change needs to find solutions for retention and proper utilization water. This study proposes an ensemble approach identifying virtual water content (VWC) main crops on Korean Peninsula past future climates. Ensemble results with low uncertainty were obtained using three regional models, five potential evapotranspiration methods, Environmental Policy Integrated Climate (EPIC) crop model. The productivity major (rice maize) under are likely...
