Elastic Exploring of Human Lung Parenchyma

نویسندگان

چکیده

Abstract The paper describes a theoretical study and exploration of authors in the field biomechanics. lung parenchyma is focused, its elastic behaviour under physiological mechanical load, pressure change during breathing. Anatomical view to human respiratory system generally introduced first together with more detailed description alveolus. Then appropriate theory elaborated, aimed on mathematical model establishing, finite element method chosen as resolving tool. computational implementation realized multi physical software based method.

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...

P-adrenoceptor of the Human Lymphocyte and Human Lung Parenchyma

I The response of the P-adrenoceptors of human lymphocytes to selective agonists and antagonists has been studied quantitatively by measuring changes in cyclic adenosine-3',5'-monophosphate (cyclic AMP) levels. 2 The receptor was activated by isoprenaline and by salbutamol, and blocked by propranolol but not by practolol. A similar pattern of response was obtained with fragments of human lung t...

Mechanical properties of lung parenchyma during bronchoconstriction.

Interdependence between airways and the lung parenchyma is thought to be a major mechanism preventing excessive airway narrowing during bronchoconstriction. Because the elastance of the lung increases during bronchoconstriction, the lung's tethering force could also increase, further attenuating bronchoconstriction. We hypothesized that the bulk (kappa) and shear moduli (mu) of the lung increas...

Read-through transcripts in normal human lung parenchyma are down-regulated in lung adenocarcinoma

Read-through transcripts result from the continuous transcription of adjacent, similarly oriented genes, with the splicing out of the intergenic region. They have been found in several neoplastic and normal tissues, but their pathophysiological significance is unclear. We used high-throughput sequencing of cDNA fragments (RNA-Seq) to identify read-through transcripts in the non-involved lung ti...

[Physiotherapy in patients after lung parenchyma resection].

Lung parenchyma resection is the treatment of choice for early-stage lung cancer. The surgery involves the loss of respiratory surface and consequently leads to reduction in exercise capacity. Proper rehabilitation is essential for restoring the function and good performance of the respiratory system. Rehabilitation should be an integral part of surgical treatment. It should be implemented earl...
