The purpose of this study was to investigate the usefulness of Fuji Computed Radiography (FCR) 5501D by comparing it with FCR 5000 and a screen-film system (S/F). Posteroanterior chest radiographs of ten patients with no abnormality on chest CT scans were obtained with FCR 5501D, FCR 5000, and S/F. Six observers (three radiologists and three radio-technologists) evaluated the visibility of nine...
By using the newly developed adhesive tumor cell culture system, we analyzed the chromosomal constitutions of primary lung tumor and nonmalignant normal lung tissue from 10 previously untreated patients with non-small cell lung cancer. Chromosomal analyses were successfully carried out in banded chromosome preparations from 10 tumor and 8 normal lung tissue samples. All analyzed tumor and norma...
The findings of mutations and the development of targeted therapies have improved lung cancer management. Still, the prognosis remains poor, and we need to know more about the genetic and epigenetic alterations in lung cancer. MicroRNAs are involved in crucial biological processes like carcinogenesis by regulating gene expression at the post-transcriptional level. In this project, we have studi...
objective(s) to determine the potential toxic effects of manual soldering flux cored solder wire on lung of the rat as an experimental model. materials and methods a total number of 48 adult male rats were divided into experimental (n= 30) and control (n= 18) groups. based on exposure time to solder fume, each group was further subdivided into 2, 4 and 6 week subgroups. rats of experimental gro...
Background and Aim: Thalassemia is a hereditary anemia with treatment of lifelong blood transfusion. Iron overload in vital organs is the consequence of this treatment. According to recent studies Iron could deposit in lung without causing any symptoms and signs in the patients. Our goal in this study was to evaluate the pulmonary abnormalities by Pulmonary function test (PFT) in patients wit...
Convolutional Neural Network (CNN)-based deep learning techniques have recently demonstrated increased potential and effectiveness in image recognition applications, such as those involving medical images. Deep-learning models can recognize targets with performance comparable to radiologists when used CXR. The primary goal of this research is examine a technique on the radiography dataset detec...
Background & objectives: Paraquat is a toxic herbicide that is widely used in many countries. Paraquat selectively accumulates in the lung tissue and leads to severe pulmonary injury through the oxidative and inflammatory processes. The plant Rosa canina L. has been used for long years as an herbal medicine throughout the world. Rosa canina L. is a member of Rosacea family and shows therapeut...
Introduction: In clinical practice, distinguishing invasive lung tumors from primary tumors remains a challenge. With recent advances in understanding biological alterations of tumorigenesis and molecular analytic technologies, using these molecular alterations can be sensitive and tumor-specific as biomarker for the stratification of patients. In this study, the molecular network of miRNA-mRNA...
This study was conducted to determine the prevalence of PE in patients with V/Q scans interpreted as representing a very low probability (VLP) of PE (1-3 small segmental perfusion defects with a normal chest radiograph). An analysis of the entire data set obtained during the PIOPED study was performed. Of the total of 1,359 patients in whom the presence or absence of PE was confirmed, 80 ...
Introduction: Pneumonectomy is the standard treatment of lung cancer, even though patients should undergo several evaluations before surgery; deterioration of cardiopulmonary function after pulmonary resection is inevitable. We have evaluated the effects of digoxin on the improvement of right ventricular function and prevention of probable complications after lung resection surgery. Materials a...
