BACKGROUND The aim of this study was to investigate the effects of different delivery circuit configurations, nebulizer positions, CPAP levels, and gas flow on the amount of aerosol bronchodilator delivered during simulated spontaneous breathing in an in vitro model. METHODS A pneumatic lung simulator was connected to 5 different circuits for aerosol delivery, 2 delivering CPAP through a high...

The need for effective and safe therapies cancer is growing as aging modifying its epidemiology. Cold atmospheric plasma (CAP) has gained attention a potential anti-tumor therapy. CAP gas with enough energy to ionize significant fraction of constituent particles, forming equal numbers positive ions electrons. Timely-resolved output voltage measurement, emission spectroscopy, quantification reac...

introduction: chest x-ray (cxr) is the simplest diagnostic tool of community acquired pneumonia (cap), but it has some limitation. therefore, the aim of this study is comparing the diagnostic accuracy of cxr and chest ultrasonography (cus) in detection of cap. methods: in the present study, a consecutive sample of suspected patients with cap was underwent cus, cxr, and chest computed tomography...

Background: Diazinon (DZN) is an organophosphate pesticide commonly used for pest control in agriculture. It may engender a variety of negative effects in non-target species, including humans and animals. The objective of the present study was to evaluate the ameliorative properties of captopril (CAP), as a thiol containing an angiotensin-converting enzyme inhibitor, against DZN-induced oxidati...

Investigation of methods to effectively block the high-permeability channel and displace residual oil in small pores old oilfields is an urgent research hotspot. The heat-resistant carbon dioxide (CO 2 ) foam with high viscoelasticity low interfacial tension, which suitable for improving recovery oilfields, at same time aids sequestration. In this study, a foaming agent was selected by consider...

Problem: Most research on planning to mitigate climate change has focused on reducing CO2 emissions from coal-fıred power plants or the transportation sector. The contribution of forests to lowering net CO2 emissions has largely been overlooked. U.S. forests already offset about one eighth of the nation's annual CO2 emissions and have the potential to offset more, all at a relatively low cost. ...

background and aim: an important criterion for success assessment of implant-supported prostheses is marginal fit. vertical and horizontal discrepancy can result in loosening of the prosthetic screw, crestal bone resorption, peri-implantitis and loss of osseointegration. despite careful attention to waxing, investing, and casting, marginal discrepancies are inevitable. the aim of this study was...

climate change is one of the major global concerns. emission of anthropogenic greenhouse gases is the main cause of climate change. one way of reducing the emissions is the application of carbon capture and storage (ccs) in geological formations. in this study, feasibility of ccs was studied in an iranian gas production area located in the northern persian gulf coast in the south of country. th...
