Improving the course and outcome of patients with acute respiratory distress syndrome presents a challenge. By understanding the immune status of a patient, physicians can consider manipulating proinflammatory systems more rationally. In this context, corticosteroids could be a therapeutic tool in the armamentarium against acute respiratory distress syndrome. Corticosteroid therapy has been studied in three situations: prevention in high-risk patients, early treatment with high-dose, short-course therapy, and prolonged therapy in unresolving cases. There are differences between the corticosteroid trials of the past and recent trials: today, treatment starts 2-10 days after disease onset in patients that failed to improve; in the past, the corticosteroid... |

ABSTRACT: The micas are rock forming mineral of the phyllosillicates group. The weathering of these minerals is fundamental in the understanding of potassium, silicon and magnesium liberation processes to the soil. the existent studies shown that the main factors that control the micas weathering are the pH of the solutions, the temperature, the size of the particles and the superficial area. The micas weathering is incongruous, in other words, always new minerals are formed as dissolution products, as vermiculite, kaolinite and goethite. These products can precipitate in the surface of the mica, especially the iron oxides of iron, and they impede the contact with its surface, reducing the dissolution kinetics. The structure of the micas is also a decisive... |

Abstract Viral infections have long been the cause of severe diseases to humans, increasing morbidity and mortality rates worldwide, either in rich or poor countries. Yellow fever virus, H1N1 virus, HIV, dengue virus, hepatitis B and C are well known threats to human health, being responsible for many million deaths annually, associated to a huge economic and social cost. In this context, a recently introduced flavivirus in South America, called Zika virus (ZIKV), led the WHO to declare in February 1st 2016 a warning on Public Health Emergency of International Concern (PHEIC). ZIKV is an arbovirus of the Flaviviridae family firstly isolated from sentinels Rhesus sp. monkeys at the Ziika forest in Uganda, Africa, in 1947. Lately, the virus has well adapted... |
