Italian Ryegrass Establishment by Self-Seeding in Integrated Crop-Livestock Systems: Effects of Grazing Management

Recent reports have indicated that integrated crop-livestock systems (ICLS) can enhance sustained crop and livestock production by efficiently using agricultural system resources (Liu et al. 2012). In the subtropical South American regions, soybean (Glycine max L. Merril) and maize (Zea Mays L.) crops are widely grown after Italian ryegrass (Lolium multiflorum Lam) pastures. In this system, the pasture may be established by self-seeding. Self-seedling reduces pasture production costs and extends the grazing period. The stoking method, and especially the grazing intensity, can greatly affect the quantity of seeds added to the soil by affecting the demography of the reproductive tillers. In subtropical areas where Italian ryegrass is used for winter pastures in ICLSs, the effects of crop rotation, stocking methods or grazing intensities on the subsequent ability of Italian ryegrass to self-seed are unknown. The objectives of this study are to evaluate the effects of management practices (crop rotation, stocking method and herbage allowance) on the establishment of Italian ryegrass pastures by self-seedling in an ICLS

Evidences of herbal medicine-derived natural products effects in inflammatory lung diseases

Pulmonary inflammation is a hallmark of many respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and acute respiratory syndrome distress (ARDS). Most of these diseases are treated with anti-inflammatory therapy in order to prevent or to reduce the pulmonary inflammation. Herbal medicine-derived natural products have been used in folk medicine and scientific studies to evaluate the value of these compounds have grown in recent years. Many substances derived from plants have the biological effects in vitro and in vivo, such as flavonoids, alkaloids, and terpenoids. Among the biological activities of natural products derived from plants can be pointed out the anti-inflammatory, antiviral, antiplatelet, antitumor anti-allergic activities, and antioxidant. Although many reports have evaluated the effects of these compounds in experimental models, studies evaluating clinical trials are scarce in the literature. This review aims to emphasize the effects of these different natural products in pulmonary diseases in experimental models and in humans and pointing out some possible mechanisms of action.CNPq [300546/2012-2, 304465/2012-7, 476877/2012-1]FAPESP [2010/14831-3, 2011/15817-7, 2008/55359-5]Instituto de Ciências Ambientais, Químicas e Farmacêuticas, Federal University of São Paulo, Diadema-SP 09972-270, BrazilSchool of Medicine, University of São Paulo, São Paulo-SP 01246903, BrazilInstituto de Saúde e Sociedade, Federal University of São Paulo, Santos-SP 11015-020, BrazilInstituto de Ciências Ambientais, Químicas e Farmacêuticas, Federal University of São Paulo, Diadema-SP 09972-270, BrazilInstituto de Saúde e Sociedade, Federal University of São Paulo, Santos-SP 11015-020, BrazilCNPq: 300546/2012-2CNPq: 304465/2012-7CNPq: 476877/2012-1FAPESP: 2010/14831-3FAPESP: 2011/15817-7FAPESP: 2008/55359-5Web of Scienc
