Laparoscopic and thoracoscopic whole-stomach esophagectomy with preoperative pyloric balloon dilatation for esophageal cancer: a prospective multicenter case-series outcome.

Introduction: To mitigate gastroparesis as well as other post-operative complications, we undertook a prospective multicenter study to assess the feasibility, safety, and efficacy in the short-term outcomes of laparoscopic and thoracoscopic whole stomach esophagectomy with preoperative pyloric balloon dilatation.

Methods: A prospective descriptive study on 37 patients with laparoscopic and thoracoscopic whole stomach esophagectomy with preoperative pyloric balloon dilatation from January 2019 to March 2023. The perioperative indications, clinical data, intra-operative index, pathological postoperative specimens, postoperative complications, and follow-up results were retrospectively evaluated.

Facile route for preparation of cuprous oxide/copper/cupric oxide nanoparticles by using simultaneous electrochemical and reduction reaction.

Cuprous oxide/copper/cupric oxide nanoparticles were synthesized through a hybrid process involving anodic dissolution and a controlled redox reaction between NaOH and glucose in the solution. The study demonstrates the structural manipulation of the material by varying the reaction components within the solution. Morphology, structural analyses using SEM (Scanning Electron Microscope), EDX (Energy-dispersive X-ray spectroscopy), TEM (Transmission Electron Microscope), FTIR (Fourier Transform Infrared Spectroscopy), XRD (X-ray diffraction), and XPS (X-ray photoelectron spectroscopy) unveiled the tunability of the material's structure based on the reaction components.

Methods: The period of interest for this case-control study was February to July 2019.

Subtotal Laryngectomy with Epiglottic Reconstruction for Glottic Carcinoma: A Single Institutional Experience.

Aim: Laryngeal cancer is a common form of head and neck cancer in Vietnam where the current treatment is surgery. Subtotal laryngectomy with epiglottic reconstruction, a conservative surgery, allows removal of anterior commissure including thyroid cartilage and paraglottic space and provides a maximum restoration of the anatomical structure of the larynx.

Purpose: To evaluate the results, the safety and effectiveness of patients who were treated with subtotal laryngectomy with epiglottic reconstruction.

Objective: There have been surgical procedures to reconstruct the gastrointestinal continuity after distal gastrectomy. This study is aimed at comparing the surgical outcomes of reconstructing gastrointestinal continuity by the method of Finsterer and Roux-en-Y after distal gastrectomy due to cancer. .

Data on cerebral palsy in Vietnam will inform clinical practice and policy in low and middle-income countries.

Purpose: To document known risk factors, clinical severity, associated impairments and rehabilitation status of children presenting with cerebral palsy (CP) to the National Children's Hospital (NCH) in Hanoi, Vietnam.

Materials And Methods: Active prospective ascertainment of cases of CP presenting between June and November 2017 to the NCH using surveillance modelled on the Paediatric Active Enhanced Disease Surveillance system in Australia.

Results: Data were collected on 765 children with CP (mean age: 2 years 7 months (SD 2 y 6 mo).

Particulate matter accumulation capacity of plants in Hanoi, Vietnam.

Population growth, urbanization, environmental conditions and rapid development have caused particulate matter (PM) levels to rise above all national and international health standards during the last two decades in many South-East Asian countries. These PM levels needs to be reduced urgently as they increase the risk of cardiovascular and respiratory health problems for millions of people. Plants have shown to efficiently reduce PM in the air by accumulation on their leaves.

Marine biodiversity research in the Ryukyu Islands, Japan: current status and trends.

Marine biodiversity and derived ecosystem services are critical to the healthy functioning of marine ecosystems, and to human economic and societal well-being. Thus, an understanding of marine biodiversity in different ecosystems is necessary for their conservation and management. Coral reefs in particular are noted for their high levels of biodiversity, and among the world's coral reefs, the subtropical Ryukyu Islands (RYS; also known as the Nansei Islands) in Japan have been shown to harbor very high levels of marine biodiversity.

Unexpected High Diversity of Terrestrial Cyanobacteria from the Campus of the University of the Ryukyus, Okinawa, Japan.

Terrestrial cyanobacterial strains were isolated from the Nishihara campus of the University of the Ryukyus, Okinawa, Japan. The 13 sampling sites were distributed in a 200 m radius and appeared as dry, blackened stains. From these small areas, 143 cyanobacterial strains were established.

Evidence for a primate origin of zoonotic Helicobacter suis colonizing domesticated pigs.

Helicobacter suis is the second most prevalent Helicobacter species in the stomach of humans suffering from gastric disease. This bacterium mainly inhabits the stomach of domesticated pigs, in which it causes gastric disease, but it appears to be absent in wild boars. Interestingly, it also colonizes the stomach of asymptomatic rhesus and cynomolgus monkeys.

Isolation and antifungal activity of methyl 2,3-dihydroxybenzoate from Paenibacillus elgii HOA73.

The aim of the present study is to describe the purification and identification of methyl 2,3-dihydroxybenzoate (M2,3DB), isolated for the first time from Paenibacillus elgii HOA73, and to subsequently investigate its antifungal activity against important plant pathogens. The results show that M2,3DB can be purified by many different chromatographic techniques and is identified as methyl 2,3-dihydroxybenzoate based on nuclear magnetic resonance (NMR) and liquid chromatography-mass spectrometry (LC-MS) spectra analyses. M2,3DB was firstly evaluated for its antifungal activity, where the growth of Botrytis cinerea and Rhizoctonia solani was almost completely inhibited at an M2,3DB concentration of 50 μg/mL.

Isolation and characterization of an antimicrobial lipopeptide produced by Paenibacillus ehimensis MA2012.

In this study, a novel lipopeptide antibiotic was isolated from the culture supernatant of Paenibacillus ehimensis strain MA2012. After analyses by mass spectrometry (MS), nuclear magnetic resonance (NMR), and high resolution mass spectrometry (HR-MS/MS) the compound was identified to be polypeptin C consisting of 3-hydroxy-4-methyl-hexanoic acid moiety and nine amino acids as peptide body. It has the same molecular mass (1115 Da) with that of polypeptin A and B but the amino acid positions differ.
