Urban air pollution is a serious worldwide problem due to its impact on human health. In the past 60 years, growing evidence established a correlation between exposure to air pollutants and the developing of severe respiratory diseases. Recently particulate matter (PM) is drawing more public attention to various aspects including historical backgrounds, physicochemical characteristics, and its ...
Inflammation, the process aimed at restoring homeostasis after an insult, can be more damaging than the insult itself if uncontrolled, excessive, or prolonged. The inflammasome is an intracellular multimeric protein complex that regulates the maturation and release of proinflammatory cytokines of the IL-1 family in response to pathogens and endogenous danger signals. Growing evidence indicates ...
Background Bronchiectasis may be associated to chronic respiratory failure, whereas lung transplantation (LTx) is the only long term treatment. According ISHLT registries, cystic fibrosis (CF) is the third cause for LTx (16.8%) and the best survival in five years (60%). Non-CF bronchiectasis corresponds to only 2.8% The aim of this study is to describe our experience with LTx for patients with ...
In nongranulomatous fibrotic lung conditions, we have recently shown that early collagen synthesis by myofibroblasts occurs in an extracellular matrix rich in the proteoglycan versican. We hypothesized that versican is associated with the process of collagen synthesis resulting from chronic inflammation. In this study, we examined the localization of proteoglycans and collagen in the granulomat...
Genetic studies in familial lung fibrosis have demonstrated an association with surfactant protein C genes: two mutations have been found resulting in protein misfolding and causing type-II epithelial cell injury. Remarkably, different histological patterns were observed in the affected subjects, suggesting the influence of modifier genes and/or environmental factors. Surfactant protein C gene ...
به دلیل نقش حیاتی ریه در بدن انسان و شیوع بیماری های آن، مدلسازی سیستم تنفس از دیرباز مورد توجه بوده است. بنابراین شناسایی عملکرد سیستم تنفسی از اهمیت بسزایی برخوردار است. خصوصا برای شناخت فیزیولوژیک ریه و نیز تشخیص و درمان بیماری های ریوی و جنبه های دیگر مثل کاربردهای کمک تنفسی شناخت این ارگان و مدلسازی آن اهمیت فراوانی دارد. تاکنون مدل های متفاوتی از سیستم تنفس ارایه شده است ولی کاملی که بتوا...
Background: Lung leiomyoma and pulmonary arterio-venous malformation (PAVM) are both rare diseases. Occurrence of them in a patient is rare too. Because of their limited signs and symptoms and so serious complications, accurate diagnosis of both diseases is important.Case report: We present a 73 -year old female with PAVM combine with a coincidental solid mass in left upper lobe. Because of fis...
