Successful robotic-assisted resection of an esophageal duplication cyst in the upper thoracic esophagus: A case report with surgical video.

Esophageal duplication cysts are rare congenital noncancerous growths. Symptoms of this disease are reported to be asymptomatic in approximately 70% but include respiratory symptoms such as coughing and difficulty breathing. Minimally invasive removal of these cysts without esophagectomy is typically recommended.

How do we prevent severe intra-abdominal infectious complications following minimally invasive gastrectomy for cancer? The usefulness of a novel marker using computed tomography images (minimum umbilicus-vertebra diameter) and robotic surgery.

Background: Intra-abdominal infectious complications (IAICs) following minimally invasive gastrectomy (MIG) for cancer sometimes worsen short- and long-term outcomes. In this study, we focused on the minimum umbilicus-vertebra diameter (MUVD) in preoperative computed tomography (CT) images and robotic surgery to prevent severe IAIC occurrence.

[Surgical Technique for Mesorectal Division in the Robotic Anterior Resection for Rectal Cancer].

Since April 2018, robot-assisted rectal resection has been approved as an insurance medical treatment, and robot- assisted rectal resection is rapidly becoming widespread. Even in robot-assisted laparoscopic surgery, mesorectal division is difficult in a narrow pelvic cavity. At the beginning of the operation, Vessel Sealer ExtendTM(price 89,250 yen)was used, but as the procedure became stable, the mesorectal division was started with bipolar forceps and monopolar scissors.

Jejunal Mesentery Preservation Reduces Leakage at Esophagojejunostomy After Minimally Invasive Total Gastrectomy for Gastric Cancer: a Propensity Score-Matched Cohort Study.

Purpose: The mesentery of the jejunum (MJ) of the Roux limb is conventionally divided when Roux-en-Y reconstruction is performed after total gastrectomy for gastric cancer (GC). However, the impact of dividing or preserving the MJ on anastomotic leakage (AL) at the esophagojejunostomy (EJS) site after minimally invasive total gastrectomy for GC is unclear.

Methods: This retrospective cohort study enrolled 226 patients with GC who underwent EJS after laparoscopic or robotic total gastrectomy, including preservation of the MJ (n = 87) and division of the MJ (n = 137).

Ingenuity and tips for laparoscopic local resection for local recurrence of early gastric cancer after endoscopic submucosal dissection: A case report.

Introduction And Importance: The presence of severe comorbidities is associated with poor surgical outcomes in patients who undergo curative resection for gastric cancer. Herein, we present a report of laparoscopic local resection (LLR) for the local recurrence of gastric cancer in a patient with severe comorbidities.

Case Presentation: A 73-year-old man underwent endoscopic submucosal dissection (ESD) for an early gastric cancer located at the greater curvature of the gastric antrum.

In-materio reservoir working at low frequencies in a AgS-island network.

A AgS-island network is fabricated with surrounding electrodes to enable it to be used as a reservoir for unconventional computing. Local conductance change occurs due to the growth/shrinkage of Ag filaments from/into each AgS island in the reservoir. The growth/shrinkage of Ag filaments is caused by the drift of Ag cations in each AgS island, which results in a unique non-linear response as a reservoir, especially at lower frequencies.

Quantum Conductance in Memristive Devices: Fundamentals, Developments, and Applications.

Quantum effects in novel functional materials and new device concepts represent a potential breakthrough for the development of new information processing technologies based on quantum phenomena. Among the emerging technologies, memristive elements that exhibit resistive switching, which relies on the electrochemical formation/rupture of conductive nanofilaments, exhibit quantum conductance effects at room temperature. Despite the underlying resistive switching mechanism having been exploited for the realization of next-generation memories and neuromorphic computing architectures, the potentialities of quantum effects in memristive devices are still rather unexplored.

Resistive Switching Memristor: On the Direct Observation of Physical Nature of Parameter Variability.

Ion-based memristive switching has attracted widespread attention from industries owing to its outstanding advantages in storage and neuromorphic computing. Major issues for achieving brain-inspired computation of highly functional memory in redox-based ion devices are relatively large variability in their operating parameters and limited cycling endurance. In some devices, volatile and nonvolatile operations often replace each other without changing operating conditions.

Asporin Expression on Stromal Cells and/or Cancer Cells Might Be A Useful Prognostic Marker in Patients with Diffuse-Type Gastric Cancer.

Background: Asporin (ASPN), a member of the proteoglycan family, has been shown to have a close correlation with cancer progression. It is not known whether ASPN is an oncogenic driver or a tumor suppressor in human gastric cancer. We sought herein to determine the relationship between ASPN expression and clinicopathological features of gastric cancer.

Dioxotriazine derivatives as a new class of P2X receptor antagonists: Identification of a lead and initial SAR studies.

P2X receptor is an ATP-gated ion channel, mainly localized on peripheral sensory neurons. Currently, several clinical trials are being conducted with P2X receptor antagonists for the treatment of chronic pain or cough. To identify a P2X lead compound, we reexamined the HTS evaluation compounds and selected dioxotriazine derivatives from which we identified a hit compound.

[A Case of Metastatic Breast Cancer That Recovered from Diffuse Alveolar Damage Associated with Everolims].

A 68-year-old woman was receiving chemotherapy and endocrine therapy for right breast cancer postoperative pulmonary metastasis and local lymph node recurrence. However, she developed interstitial pneumonia 12 weeks after initiating treatment with everolimus and exemestane. Treatment with everolimus and exemestane was discontinued and steroid pulse therapy was initiated; however, she required ventilator management because of the severity of the pneumonia.

A Case of Hemorrhagic Cholecystitis and Hemobilia Under Anticoagulation Therapy.

BACKGROUND Hemorrhagic cholecystitis is a rare disease which can be fatal in some cases. Hemorrhagic cholecystitis can sometimes be confused with common biliary diagnoses, as its symptoms imitate other hepatobiliary diseases. We report a case of hemorrhagic cholecystitis with hemobilia caused by the administration of anticoagulant agents.

Pyrrolinone derivatives as a new class of P2X3 receptor antagonists. Part 3: Structure-activity relationships of pyrropyrazolone derivatives.

The P2X3 receptor is an attractive target for the treatment of pain and chronic coughing, and thus P2X3 antagonists have been developed as new therapeutic drugs. We previously reported selective P2X3 receptor antagonists by derivatization of hit compound 1. As a result, we identified hit compound 3, the structure of which was similar to hit compound 1.
