Respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and lung infections have critical consequences on mortality and morbidity in humans. The aims of the present study were to examine the mechanisms by which CXCL12 affects MUC1 transcription and airway inflammation, which depend on activator of G-protein signaling (AGS) 3 and to identify specific molecules that sup...

The imaging of subsurface targets, such as landmines, using Ground Penetrating Radar (GPR) is becoming an increasingly important area of research. Conventional image formation techniques expend large amounts of computational resources on fully resolving a region, even if there is a large amount of clutter. For example, standard backprojection algorithms require O(N). However, by using multi-res...

Ground-penetrating radar (GPR) has recently gained a wide acceptance in the archaeological community as a method that can quickly and accurately locate buried archaeological features, artifacts, and important cultural strata in the near-surface. The GPR method has been especially effective in certain sediments and soils between about 20 cm and 5 m below the ground surface, where the targets to ...

Ground penetrating radar (GPR) systems are equipment able to acquire underground images scanning the surface of soil/pavement under investigation. Usually GPR records its own position along scan line using a mechanical odometer, i.e., rolling wheel in contact with ground. Unfortunately, this simple and cheap solution can be not effective on uneven terrains. In article, completely different is p...

The use of multidetector computed tomography (MDCT) is an integral part of contemporary diagnostics of Graves‘ orbitopathy. The aim of this study was to assess proptosis measurement by MDCT and to compare it to the current standard, Hertel exophthalmometry. A cross-sectional study was conducted at the Clinical Centre of Serbia and included 91 patients (19 male and 72 female) with verified Grave...

Quadrotor helicopters and robot manipulators are used widely for both research and industrial applications. Both quadrotors and manipulators are difficult to model. Quadrotors have complex dynamic models, especially at high speeds. Obtaining an accurate model of manipulator dynamics is often difficult, due to inaccurate values for link parameters and dynamics such as friction which are difficul...

Alpha/beta-type small, acid-soluble proteins (SASP) of dormant spores of Bacillus subtilis bind to DNA and increase its resistance to a variety of damaging agents both in vivo and in vitro. When spores germinate, degradation of alpha/beta-type SASP is rapidly initiated by a sequence-specific protease, which is termed GPR. Three mutations have been introduced into the B. subtilis sspC gene, whic...

Natural soil pipes are common and significant in upland blanket peat catchments yet there are major problems in finding and defining the subsurface pipe networks. This is particularly important because pipeflow can contribute a large proportion of runoff to the river systems in these upland environments and may significantly influence catchment sediment and solute yields. Traditional methods su...

It has now been well established that the depth of bedrock is a key parameter in assessing the impact of local site conditions on seismic hazard analysis. Where conventional geotechnical testing like standard penetration test (SPT) or cone penetration test (CPT) requires a far greater cost and manpower to be used for such purposes, geophysical testing like ground-penetrating radar (GPR) and mul...

The objectives of our study were to assess the feasibility of using ground-penetrating radar (GPR) to study roots over a broad range of soil conditions in the southeastern United States. Study sites were located in the Southern Piedmont, Carolina Sandhills and Atlantic Coast Flatwoods. At each site, we tested for selection of the appropriate antenna (400 MHz versus 1.5 GHz), determined the abil...
