Electron correlation effects on uranium isotope fractionation in U(VI)-U(VI) and U(IV)-U(VI) equilibrium isotopic exchange systems.

Uranium isotope fractionation has been extensively investigated in the fields of nuclear engineering and geochemical studies, yet the underlying mechanisms remain unclear. This study assessed isotope fractionations in U(VI)-U(VI) and U(IV)-U(VI) systems by employing various relativistic electron correlation methods to explore the effect of electron correlation and to realize accurate calculations of isotope fractionation coefficients (). The nuclear volume term, ln , the major term in , was estimated using the exact two-component relativistic Hamiltonian in conjunction with either HF, DFT(B3LYP), MP2, CCSD, CCSD(T), FSCCSD, CASPT2, or RASPT2 approaches for small molecular models with high symmetry.

[A Case of Squamous Cell Carcinoma of the Lung from Gastrointestinal Perforation Due to Small Intestinal Metastasis].

An 80s male, with a medical history of hypertension, hyperuricemia, and atrial fibrillation, visited our emergency outpatient department with vomiting and diarrhea as the chief complaint in August 2017. The blood examination revealed a high level of inflammatory reaction. The plain abdominal CT revealed fluid retention contacting the small intestine and intraabdominal free gas.

Novel minimally invasive approach to lymph node dissection around the left renal vein in patients with esophagogastric junction cancer.

The left renal vein lymph node (LRVLN) may be the extended locoregional node in esophagogastric junction cancer; however, only open-surgical methods of dissection have been reported. We therefore developed a novel minimally invasive laparoscopic method for LRVLN dissection. Following esophagectomy, the stomach was mobilized and LRVLN dissection was started by taping the pancreatic body using two silicone drains.

Efficacy of prewarming prophylaxis method for intraoperative hypothermia during thoracoscopic esophagectomy.

Background: This study was performed to elucidate the clinical efficacy of the prewarming prophylaxis method for intraoperative hypothermia during thoracoscopic esophagectomy for esophageal cancer.

Methods: We enrolled 100 consecutive patients with esophageal cancer. Two patients in the prewarming group could not undergo thoracoscopic esophagectomy because of conversion to thoracotomy.

Case report: Gastric tube cancer after esophagectomy-Retrograde perfusion after proximal resection of right gastroepiploic artery.

Introduction: We report a case of a 57-year-old patient with gastric tube cancer after subtotal esophagectomy and retrosternal gastric pull up.

Case Presentation: The patient developed gastric cancer 4 years after undergoing treatment for esophageal squamous cell cancer; the treatments included thoracoscopic subtotal esophagectomy, gastric pull-up reconstruction via a retrosternal route in salvage setting following definitive chemoradiation. Because the gastric tube cancer was located around the pylorus, transabdominal partial resection, which is much less invasive than total resection via sternotomy, was performed.

Impact of pathologically assessing extranodal extension in the thoracic field on the prognosis of esophageal squamous cell carcinoma.

Background: This study aimed to elucidate the impact of extranodal extension, pathologically assessed according to new diagnostic criteria, on the prognosis of esophageal squamous cell carcinoma. Extranodal extension has been shown to be a prognostic indicator for head and neck cancers; however, its utility in esophageal squamous cell carcinoma has not been demonstrated.

Methods: We enrolled 174 consecutive esophageal squamous cell carcinoma patients who had undergone esophagectomy with lymph node dissection in the three fields.

A case report of postoperative VRSA enteritis: Effective management of rifampicin for vancomycin resistant Staphylococcus aureus enteritis after esophagectomy and colon reconstruction.

Introduction: Vancomycin is one of the most widely used antibiotics for the treatment of serious infectious caused by methicillin-resistant Staphylococcus aureus (MRSA). However, reduced susceptibility of S. aureus to vancomycin has been observed in recent years.

ELISA measurement for urinary 3-hydroxyproline-containing peptides and its preliminary application to healthy persons and cancer patients.

Background/aim: We reported that endogenous urinary 3-hydroxyproline (3-Hyp) is useful for cancer screening because cancer invasion involves the destruction of basement membrane. A simple and sensitive assay is desired.

Patients And Methods: An ELISA method using a specific antibody against a synthetic peptide of 10 amino acids including 3-Hyp corresponding to the amino acid sequences of collagen type IV alpha chain was applied to urine samples from 180 healthy controls and 22 cancer patients.
