Abstract The Puna grasslands support grazing systems that produce meat and wool in multi-species herds, especially from llama (Lama glama) and sheep. However, it is yet unknown whether grazing pressure can modify grassland structure and Plant Functional Types diversity and cover in Puna grasslands. We analyzed the relationship between grazing pressure and Plant Functional Types by comparing transects located near stockyards (high grazing pressure) and far from them (low pressure) and by evaluating the relationship between the Plant Functional Types cover to a Grazing Pressure Index (GPI). This index incorporates the heterogeneity of traditional pastoral management. At… More >

Abstract Punarnavine (PN) has been isolated from the roots of Boerhaavia diffusa L. (Nyctaginaceae). It is an important medicinal plant with a vast historical ethnopharmacological background. Its identification resulted from the interrogation of ‘Punarnava’, a tribal medicinal product. The molecule exhibited its position as incipient anticancer therapeutic agent. The inhibition of NFκB, ATF-2, c-Fos, and CREB-1 are one of the underlying mechanisms of anticancer action along with modification of the immune system. These signalling molecules are upregulated in the cancer microenvironment. Punarnavine also modified the release of interleukins, i.e., upregulated IL-2, IL-7, IL-10, IL-12, IFN-γ, while downregulated… More >
