Blunt esophageal injury is an unusual organ injury that has unclear clinical symptoms due to the overlap of thoracoabdominal trauma in the setting of multiple traumas. The treatment options vary depending on the patient's clinical symptoms, the extent of esophageal damage, and the time from the onset of damage to diagnosis. This article presents a case of a young male patient receiving emergency treatment after a traffic accident.

Methods: A prospective study was carried out on 61 patients undergoing VATS thymectomy for MG class I, IIA with thymoma in the period from 10/2013 to 5/2019. The WHO histopathological classification, Masaoka's stages and MG grading using the guidelines of the Medical Scientific Advisory Board of the Myasthenia gravis foundation of America (MGFA) were used.
The present study aims to investigate the adsorption of synthesized poly(2-acrylamide-2-methylpropane sulfonic acid) (PAMPs) onto alumina nanoparticles and their application in the removal of ciprofloxacin (CFX) antibiotic from a water environment. The PAMPs were successfully synthesized and characterized by nuclear magnetic resonance and gel-permeation chromatography methods. The number- and weight-average molecular weights of PAMPs were 6.

Adsorption of PSS onto positively charged alumina surface increased with increasing ionic strength, indicating that non-electrostatic and electrostatic interaction controlled the adsorption. The removal of an emerging antibiotic ciprofloxacin (CFX) from water environment using PSS-modified alumina (PMA) was also studied.

Background: Lung volume reduction surgery (LVRS) was introduced to alleviate clinical conditions in selected patients with heterogenous emphysema. Clarifying the most suitable patients for LVRS remained unclear.
Aim: This study was undertaken to specifically analyze the preoperative factor affecting to LVRS.
In the present study, alumina nanoparticles (nano-alumina) which were successfully fabricated by solvothermal method, were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), and Brunauer⁻Emmett⁻Teller (BET) methods. The removal of cationic dye, Rhodamine B (RhB), through adsorption method using synthesized nano-alumina with surface modification by anionic surfactant was also investigated. An anionic surfactant, sodium dodecyl sulfate (SDS) was used to modify nano-alumina surface at low pH and high ionic strength increased the removal efficiency of RhB significantly.

Behaviors showing significant twinning during initial in-plane compression and untwinning in subsequent tension at and slightly above room temperature were recorded. Strong yielding asymmetry and nonlinear hardening behavior were also revealed.
