the purpose of this study was to determine the clinical significance of changes in the plasma adiponectin concentration in patients with bronchial asthma and to test the association between the single nucleotide polymorphisms (snps) rs2241766 and rs1501299 in the adipoq gene and bronchial asthma in the chinese li population.we selected 120 cases and 120 controls, and plasma adiponect...
BACKGROUND Mucormycosis is a rare and life-threatening invasive fungal infection. Pulmonary mucormycosis commonly occurs in patients with severe neutropenia. Typically, pulmonary mucormycosis causes tissue necrosis resulting from angioinvasion and subsequent thrombosis, so most cases can occur with necrotizing pneumonia and/or hemoptysis. Some complex cases may invade adjacent organs, such as t...
Organotypic 3D cultures of epithelial cells are grown at the air-liquid interface (ALI) and resemble the in vivo counterparts. Although the complexity of in vivo cellular responses could be better manifested in coculture models in which additional cell types such as fibroblasts were incorporated, the presence of another cell type could mask the response of the other. This study reports the impa...
BACKGROUND Osteopontin (OPN) contributes to the development of T helper 1 (Th1)-mediated immunity and Th1-associated diseases. However, the role of OPN in bronchial asthma is unclear. Corticosteroids reduce airway inflammation, as reflected by the low eosinophil and T-cell counts, and the low level of cytokine expression. We investigated OPN production and the inhibitory effects of corticostero...
Capturing the effects of exposure in a specific target organ is a major challenge in risk assessment. Exposure to cigarette smoke (CS) implicates the field of tissue injury in the lung as well as nasal and airway epithelia. Xenobiotic metabolism in particular becomes an attractive tool for chemical risk assessment because of its responsiveness against toxic compounds, including those present in...
The management of complex airway disorders is challenging, as the stent placement usually results in several complications. Tissue reaction to foreign body, poor mechanical properties and inadequate fit are some reported problems. For this reason, design customized biomedical devices improve accuracy clinical has recently gained interest. aim present study introduce a parametric tool for new tr...
The pattern and clinical implications of bronchial bacterial colonization have been widely investigated in patients with chronic lung disease, particularly chronic obstructive pulmonary disease. The main aim of this study was to determine the frequency and risk factors for bronchial colonization in lung cancer patients who have undergone surgical resection. Forty-one patients with resectable lu...
