background: the metabolically active tumor cells may be characterized by a pronounced adenosine release that regulates the growth and development of the tumor. consequently, the expression pattern of defined receptor subtypes will be an important determinant for specific effects of adenosine on the control of tumor cell growth. in recent studies, the expression profile, signal transduction, mol...

the sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. the passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematopoieti...

conclusion the technical performance of pet scan is significantly higher than similar technologies for staging and treatment of nsclc. in addition, it might slightly improve the treatment process and lead to a small level of increase in the quality adjusted life year (qaly) gained by these patients making it cost-effective for the treatment of nsclc. results the total annual running cost of a p...

among the drug delivery and targeting (ddt) routes, lung alveolar epithelium has been given enormous attentions in terms of the delivery of a wide range of macromolecules such as gene- or protein-based nanopharmaceuticals. however, little is known about cellular modulation of lung transport characteristics by endogenous and/or exogenous agents. thus, in the current study, impact of dexamethason...

the lung cancer is one of the most dangerous cancers and is also the leading cause of cancer death worldwide, accounting for about 1.3 million deaths annually. however in clinical practice, lung cancer therapies commonly do with chemotherapy, although it is hard because the lung cancer may progress to metastasis stage. the metastasis of lung cancer is highly dependent of expression of matrix me...

miliary mottling on chest radiography is seen in miliary tuberculosis, certain fungal infections, sarcoidosis, coal miner’s pneumoconiosis, silicosis, hemosiderosis, fibrosing alveolitis, acute extrinsic allergic alveolitis, pulmonary eosinophilic syndrome, pulmonary alveolar proteinosis, and rarely in hematogenous metastases from the primary cancers of the thyroid, kidney, trophoblasts, and so...

Tumor-targeted therapies are playing growing roles in cancer research. The exploitation of these powerful therapeutic modalities largely depends on the discovery of tumor-targeting ligands. Phage display has proven a promising high throughput screening tool for the identification of novel specific peptides with high binding affinity to cancer cells. In the present study, we describe the use of ...
