[Retracted] SIRT3 regulates cell proliferation and apoptosis related to energy metabolism in non‑small cell lung cancer cells through deacetylation of NMNAT2.

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that the control β‑actin western blots shown in Fig. 4C were strikingly similar to data appearing in different form in Fig. 9B in a previously published paper featuring one author in common; moreover, the immunoblotting experiments shown in Figs.

Influence of computed tomography contrast agent on radiotherapy dose calculation for pancreatic carcinoma: A dosimetric study based on tomotherapy and volumetric-modulated arc therapy techniques.

The main purpose of our investigation was to quantify the dosimetric influence of intravenous contrast agent for pancreatic cancer radiotherapy treatment. This study focused on complex modulated irradiation techniques of tomotherapy (TOMO) and volumetric-modulated arc therapy (VMAT) to investigate if novel conformal treatment methods could reduce the influence of contrast agent. In our study, patients with pancreatic cancer were enrolled to have 2 computed tomography (CT) scans in the same position without and with intravenous contrast agent for treatment planning.

[Investigation of field width and pitch in tomotherapy treatment plans for brain metastases from lung cancer].

Tomotherapy plans were produced using a combination of field widths (1 cm, 2.5 cm and 5 cm) and pitches (0.15, 0.

Outcome Study of Cobalt Based Stereotactic Body Radiation Therapy for Patients with Inoperable Stage III Non-small Cell Lung Cancer.

Aim of this paper is to retrospectively evaluate the efficacy and toxicity of specialized Body Cobalt based system (BCBS) treatment in the senior patients group (.65 years) with Stage III non-small cell lung carcinoma (NSCLC). A total of 49 patients (41 males and 8 females) with Stage III NSCLC according to UICC TNM classification (6(th) edition) were treated using OUR-QGD™ BCBS which was designed and manufactured in China.

The application of gamma stereotactic body radiation therapy in stage I/II non-small-cell lung cancer. Promising and encouraging outcome.

Objective: To further evaluate the efficacy and toxicity of the gamma-ray stereotactic body radiation therapy (SBRT) in patients with stage I/II non-small-cell lung cancer (NSCLC).

Methods: Twenty-nine newly diagnosed patients with stage I/II NSCLC who had no previous treatments, underwent OUR-QGD type of the gamma-SBRT at the Radiation Oncology Department, People's Liberation Army Airforce General Hospital, Beijing, China from January 2007 to July 2010. All patients were immobilized by vacuum bag, and then a slow CT scan was performed without any respiration gating.

SIRT3 regulates cell proliferation and apoptosis related to energy metabolism in non-small cell lung cancer cells through deacetylation of NMNAT2.

Lung cancer is the leading cause of death worldwide and associated with dismal prognoses. As a major mitochondrial deacetylase, SIRT3 regulates the activity of enzymes to coordinate global shifts in cellular metabolism and has important implications for tumor growth. Its role as a tumor suppressor or an oncogene in lung cancer is unclear, especially in non-small cell lung carcinoma (NSCLC).

[Dosimetric comparison of treatment plans of pancreatic carcinoma treated with body gamma knife and tomotherapy].

Fourteen patients with pancreatic carcinoma were selected. Two treatment plans were designed for each patient, including gamma knife and Tomotherapy. The dose characteristics were evaluated by DVH and were compared.

[Verification of the couch automatic movement accuracy for Hi-ART tomotherapy].

The QUASAR Penta-guide Phantom with fiducial markers was scanned, and the CT images were transferred to Pinnacle workstation. Skin and target volumes were contoured and transferred to TomoPlan treatment planning system. The phantom was scanned with Megavoltage CT (MVCT).

Prospective study of epidermal growth factor receptor tyrosine kinase inhibitors concurrent with individualized radiotherapy for patients with locally advanced or metastatic non-small-cell lung cancer.

Purpose: To establish the safety profile and efficacy of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) concurrent with individualized radiotherapy (RT) in patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC).

Patients And Methods: Between June 2007 and January 2010, 26 patients with Stage III/IV NSCLC were enrolled in this prospective study. These patients were treated with EGFR-TKIs (gefitinib 250 mg or erlotinib 150 mg, oral daily) concurrent with individualized RT with curative intent.

Dose estimation by EPR spectroscopy of tooth enamel in Chinese medical diagnostic X-ray workers.

Individual accumulated doses were determined by electron paramagnetic resonance spectroscopy of tooth enamel in Chinese medical diagnostic X-ray workers. Dose determination was performed using a specially developed automatic spectrum processing procedure. The determined dose values owing to X rays for the three workers with entry year (the year they began their career as medical diagnostic X-ray workers) in the 1950s ranged from 435 to 903 mGy, the converted effective doses ranged from 91 to 190 mSv.

Occupational exposures of Chinese medical radiation workers in 1986-2000.

Data on occupational exposures from medical uses of radiation in China during 1986-2000 are presented. Individual dose monitoring results in the reports of monitoring centres in different provinces in China during 1986-2000 were collected as the basic data. These data were summarised and then analysed.
