Abstract Background and Aim: We seek for the accurate simple method detecting sentinel nodes of gastric cancer which can be popularized in community hospitals. The indocyanine green (ICG) fluorescence‐guided is reported to sensitive. However, ordinal fluorescence cameras have gray scale imaging require a dark room. developed new device, Hyper Eye Medical System (HEMS) simultaneously detect color near‐infrared rays used under room light. This study was planned examine whether submucosal...

In this paper, we propose a low-power area-efficient redundant flip-flop for soft errors, called DICE-ACFF. Its structure is based on the reliable DICE (Dual Interlocked storage CEll) and ACFF (Adaptive-Coupling Flip-Flop). It achieves lower power at data-activity. We designed DICE-FF DICE-ACFF using 65 nm conventional bulk thin-BOX FD-SOI (Silicon Thin-BOX, SOTB) processes. area twice as large DFF. As dissipation, than DFF below 20% data activity. When activity 0%, its half of error rates...

Considering the rising popularity of electric vehicles (EVs), it is essential to enhance cruising mileage and extend lifetime batteries. To accomplish this, accurate monitoring charge discharge current battery over a wide temperature range essential. We developed compact diamond quantum sensor head with size 1 × 0.5 cm3, consisting (111) high-pressure high-temperature synthesized nitrogen-vacancy centers, by electron beam irradiation, which was adhered top multimode fiber surrounded...

Objective: To clarify whether there are any muscle synergy changes in individuals with knee osteoarthritis, and to determine analysis could be applied other musculoskeletal diseases. Methods: Subjects this study included 11 young controls (YC), 10 elderly (EC), osteoarthritis patients (KOA). Gait was assessed on a split-belt treadmill at 3 km/h. A non-negative matrix factorization (NNMF) the electromyogram data extract synergies. assess similarity of each module, we performed NNMF assuming...

Abstract Histologic examination lacks the sensitivity to detect micrometastases in gastric cancer lymph nodes. In present study, we applied a real‐time RT‐PCR approach quantitative detection of nodes and compared diagnostic power with routine histology immunohistochemistry. We studied 392 from 21 patients who underwent curative surgery. Real‐time was performed on LightCycler instrument using hybridization probe for carcinoembryonic antigen (CEA) cytokeratin‐20 (CK20) as marker genes....

Background: Delirium is syndrome characterized by acute fluctuations mental status. Patients are at increased adverse inpatient events, higher mortality and morbidity rates, prolonged hospital stays, health care costs. Methods: Participants were 2168 who had been admitted the St. Luke's International Hospital days or...

Surgeries for cancer of the esophagus are still associated with a high rate postoperative morbidity. There few reports perioperative nutritional support patients undergoing esophageal surgery, and there is insufficient evidence to recommend routine use immunonutrition in these patients. The aim this study was determine whether preoperative positively influences key clinical outcomes such as infectious complications, mortality, length hospital stay, short-term survival population. We...

Abstract We performed laparoscopic surgery for three cases of colorectal cancer using an 8K ultra‐high‐definition endoscopic system, which offers 16‐fold higher resolution than the current 2K high‐definition endoscope. The weight camera has been successfully reduced to 370 g. To maximize advantages endoscope, was by darkening room and placing a large 85‐in. display as close surgeon possible. As result, autonomic nerve preserved, membrane structure could be clearly observed. Moreover, we were...
