the production of colony-stimulating factors (csf) is delicately controlled through a complex network of humoral and environmental factors. we have studied some of the mechanisms which regulate the production of csf as compared to general protein synthesis in the lung tissue ill vitro. when lung tissue from mice was cultured for various times in serum free medium, the first detectable level of ...

computer-aided diagnosis (cad) systems can assist radiologists in several diagnostic tasks.  lung segmentation is one of the mandatory steps for initial detection of lung cancer in posterior-anterior chest radiographs. on the other hand, many cad schemes in projection chest radiography may benefit from the suppression of the bony structures that overlay the lung fields, e.g. ribs. the original ...

Background: Intensity Modulated Radiotherapy (IMRT) can improve radiotherapy (RT) results by improving healthy tissue sparing. Additionally, IMRT provides more consistent dose deliveries and suppresses secondary tumor formation. RT is a principal treatment in breast cancer (BC). Aim: To evaluate the outcome of the Radiotherapy Plans (RTP) that use IMRT technique to left breast and other organs,...

airway mucus hypersecretion health effects caused by air pollutants may range from subtle biochemical or physiological signs, such as mildly reduced lung function, to difficult breathing, wheezing, coughing and exacerbation of existing respiratory conditions such as asthma. the aim of this study was measuring the adverse health effects of air pollution on lung function of primary school student...

background: lower lung field tuberculosis is atypical presentation of pulmonary tuberculosis which often causes confusion in diagnosis. hiv/aids epidemic has considerably increased its incidence. this study was designed to identify the prevalence and different clinical conditions of lung tuberculosis in conjunction with its common clinical and radiological presentations and its treatment.   met...

Objective(s): To investigate the protective effect of S-nitrosoglutathione (SNG) pretreatment on acute lung injury (ALI) in septic rats. Materials and Methods: We constructed a rat model of sepsis by cecal ligation and perforation (CLP), and randomly divided into Sham, CLP, and CLP+SNG (0.25 and 0.5 mg/kg) groups. We used H&E; staining an...

objective: the bioscaffold can be used in tissue engineering and regenerative medicine. the scaffolds used in tissue engineering must have high porosity to facilitate accelerated angiogenesis for feeding cells and repelling cell waste outside the scaffold. in this experimental study, we attempted to produce lung three-dimensional scaffold and assay its effect on cell penetration and migration. ...

acute respiratory distress syndrome (ards) is a complex disorder of heterogeneous etiologies characterized by a consistent, recognizable pattern of lung injury and a potentially devastating form of acute inflammatory lung injury with a high short-term mortality rate and significant long-term consequences among survivors. recently, the new definition of ards has been published, and this definiti...

Introduction: Boron neutron capture therapy (BNCT) is recommended to treat the glioblastoma tumor. It is well known that neuron beams are more effective treatment than photon beams to treat hypoxia tumors due to interaction of neutron with nucleus and production of heavy particles such as 7Li and alpha particle. In this study to evaluate the suitability of BNCT for treating of ...
