Sonography (US) has inherent limitations for thoracic imaging because sound waves are reflected by bone and air space (such as in lung parenchyma). However, US is less expensive and more convenient than computed tomography (CT) or magnetic resonance imaging (MRI); it provides immediate information with real-time imaging, and can give information not available from a standard radiograph. This re...
Abstract Sound generating human activities so-called “anthropogenic sound” have increased ambient sound levels considerably in aquatic habitats that are markedly diverse in time and space. Sound generating human activities is now recognized as a potential driver of environmental changes in marine habitats. Iran has 750 km coastline along the Caspian Sea located in the north and around 2250 km ...
Background and Objectives: Influence of water mass on sound propagation in the Gulf of Aden underwater acoustics used for communication, navigation and identification of objects by both humans and marine mammals and for investigating the detrimental effects of anthropogenic activities (e.g. pile driving, seismic survey and ships) on marine animals. The Gulf of Aden presents a unique ecosystem t...
Materials and methods BALB/c mice were exposed to sound stress during late gestation. Maternal serum and placentas were analyzed. Fetal development was scored. Allergic asthma was induced in the offspring by using an ovalbumin protocol. We analyzed immune cells in lungs, bronchioalveolar fluid (BAL) and lung-draining lymph nodes as well as cytokine concentrations in the BAL. Further, stress-cha...
background: acute kidney injury (aki) has been recognized as one of the most complex clinical complications in modern medicine, and ischemia/reperfusion (i/r) injury is well-known as a main reason of aki. in addition, aki leads to important systemic consequences such as acute lung injury. this study was designed to investigate the role of erythropoietin (epo) on kidney function makers and tissu...
first method, samples are collected and the concentration of DON or individual DON components are monitored over time. To measure DON flux rates using 15N tracer techniques. all of the DIN forms (N~ + , NO3 -.and NO2 -) must be removed, and the DON pool must be isolated with a high efficiency. At present. there are three basic approaches used to isolate DON-wet chemistry, ion retardation, and d...
conclusions results of the current study showed the high prevalence of m. tuberculosis among the patients with lung cancer; therefore, it seems that continuous surveillance is essential to monitor the m. tuberculosis in the patients with lung cancer. results the subjects included 252 (66.3%) males and 128 (33.7%) females. based on cultural and microscopic methods, m. tuberculosis infection was ...
background: radiation-induced lung injury is a refractory side effect in lung cancer radiotherapy, the mechanism still remains unclear, hence an appropriate animal mode may become useful to investigate it. materials and methods: 50 female wistar rats were randomly divided into 5 groups, average 10 rats/cage: a. control group b. 3gy×10f c. 6gy×5f d. 12.5gy×1f e.15.3gy×1f. by different doses of r...
