Brazil is the world’s largest producer of sugarcane (Saccharum officinarum), but occurrence and severity diseases such as orange rust (Puccinia kuehnii), ring spot (Leptosphaeria sacchari), red rot (Colletotrichum falcatum) could be part several factors limiting its production reason for replacing cultivars. It important to use other forms disease control depending on time required ob...

Pseudowollastonite ceramics (beta-CaSiO3) from synthetic and natural sources were assessed with regard to their properties relevant to biomedical applications. Synthetic and natural CaSiO3 powders, with average particle size of 1.6 and 13.2 microm, respectively, were first employed. Powders were pressed and sintered at 1400 degrees C for 2 h. Pseudowollastonite was the only crystalline phase in...

The surfaces of airless planetary bodies are subject to a barrage charged particles, photons, and meteoroids. This high-energy space environment alters the creates tenuous atmosphere ejected particles surrounding celestial bodies. Experiments with well characterized analogue materials under controlled laboratory conditions needed interpret observations these atmospheres improve composition mode...

Inhalation of asbestos is associated with pathologic changes in the pleural space, including pleural thickening, pleural plaques, and mesothelioma. These processes are characterized by altered local proteolysis, cellular proliferation, and cell migration, suggesting that the urokinase-type plasminogen activator receptor (uPAR) could be involved in the pathogenesis of asbestos-induced pleural di...

Environmental impacts on autoimmunity have significant public health implications. Epidemiological studies have shown associations between exposure to airborne silicates, such as crystalline silica or asbestos, and autoimmunity, but the etiology remains unclear. The purpose of this study was to test the hypothesis that asbestos could lead to a specific pattern of autoantibodies and pathology in...
