We present an interesting case of a complete vanishing of the left main bronchus in a lung transplant recipient who had a successful outcome due to acute respiratory support with venovenous extracorporeal membrane oxygenation in order to perform airway dilation.
MAIN is software that has been designed to interactively perform the complex tasks of macromolecular crystal structure determination and validation. Using MAIN, it is possible to perform density modification, manual and semi-automated or automated model building and rebuilding, real- and reciprocal-space structure optimization and refinement, map calculations and various types of molecular stru...
In many studies, the alternative load path method (APM) has been used for progressive collapse analysis. In this method, one or several columns of the building are removed and the building response is investigated. This method ignores the initial local failure cause of building and this can affect the structural response. Investigation of ignoring the initial local failure cause of steel braced...
Introduction: One of the factors influencing on indoor air quality of the buildings is performance of HVAC (heating, ventilation, and air conditioning) systems. These systems supply clean and odorless air, with temperature, humidity, and air velocity within comfort ranges for the residents. The aim of this study was to evaluate performance HVAC system in an administrative building in Tehran. .M...
Rural housing is an important issue in Iran due to the large number of villages, their geographical dispersion, the fragile rural economy, and the crucial role of rural development in sustainable development. Considering these subjects, policies regarding rural housing development and its quality improvement are to be deduced, which results in rural housing typologies template in different clim...
BACKGROUND The loss of a normal airway is devastating. Attempts to replace large airways have met with serious problems. Prerequisites for a tissue-engineered replacement are a suitable matrix, cells, ideal mechanical properties, and the absence of antigenicity. We aimed to bioengineer tubular tracheal matrices, using a tissue-engineering protocol, and to assess the application of this technolo...
The term "fallen lung sign" refers to the collapsed lung in a dependent position, hanging on the hilum only by its vascular attachments. This is usually the result of the complete rupture of a bronchus. On chest radiograph, the diagnosis of bronchial tear is usually suspected with the persistence of a pneumothorax after chest tube insertion. An 8-year-old male patient had radiographic findings ...
In children, it has been shown that the angles of the tracheobronchial bifurcation total approximately 80 degrees; the overall mean of the right bronchial angle is about 30o, while the left bronchial angle is about 50o. This tracheobronchial relationship may explain why the tracheal tube is more likely to enter the more vertical and wider right main stem bronchus than the more obliquely placed ...
An algorithm for the automated macromolecular model building of polypeptide backbones is described. The procedure is hierarchical. In the initial stages, many overlapping polypeptide fragments are built. In subsequent stages, the fragments are extended and then connected. Identification of the locations of helical and beta-strand regions is carried out by FFT-based template matching. Fragment l...
The Joy of Learning. Main Ideas, Scaffolding, and Thinking: building new concepts by modeling: HOWTO
Walking through life can be fun and interesting, dull and boring or simply frustrating. Our walk is based not on our talents but on our decisions. Our skill in making decisions that add a little spice to each day depends on our ability to bring together facts and concepts, develop a picture of the desired outcome and then make a decision that brings us closer to that outcome. In our experience,...
