Rosmarinic acid (RosA) is a water-soluble polyphenol, which can be isolated from many herbs such as orthosiphon diffuses and rosmarinus officinalis. Previous studies have shown that RosA possesses various biological properties. In this study, we investigate the anti-osteoarthritic effects of RosA in rat articular chondrocytes. Chondrocytes were pre-treated with RosA, followed by the stimulation...

ROSA is an e-learning system, which enables the creation, storage, reuse and management of Learning Objects (LOs). LO is a collection of reusable material used to support learning, education, or training. However, since ROSA is still a centralized system, it does not provide yet a complete integration of LOs created in local ROSAs of other institutions. This paper presents the evolution of ROSA...

BACKGROUND Diabetes mellitus is one of the most common endocrinal disorders and medicinal plants continue to play an important role in the management of this disease. In this study, Rosa canina was investigated for the antioxidant and α-amylase inhibition activities. MATERIALS AND METHODS Methanolic extract of Rosa canina was investigated for its potential antioxidant activity. The extracts' ...

Learning Content Management Systems (LCMS) store and manage e-learning content and play an important role in the development of Distance Learning technology. ROSA (Repository of Objects with Semantic Access) is a LCMS that provides the creation, storage, reuse, retrieval and management of learning objects (LO). In ROSA, course structure and content (LOs) are organized according to Conceptual Ma...

The mutualistic basidiomycete Piriformospora indica colonizes roots of mono- and dicotyledonous plants, and thereby improves plant health and yield. Given the capability of P. indica to colonize a broad range of hosts, it must be anticipated that the fungus has evolved efficient strategies to overcome plant immunity and to establish a proper environment for nutrient acquisition and reproduction...

BACKGROUND Interest in Tatera indica rodent arises mostly because it is believed that this species is survived among four subspecies reported from Iran, two of which exist in Khuzestan Province. In addition, it might has a role as reservoir hosts of zoonotic cutaneous leishmaniasis in the transmission of Leishmania major in some of the widespread Asian foci including southwestern Iran. METHOD...

The genus Rosa L. (Rosaceae) was recently treated floristically for North America, but range extensions and an additional taxon have been confirmed since then and are detailed here. These new reports document range extensions in the US and Canada of some native and introduced Rosa species, and new distributions and population data for several established Rosa hybrids (nothospecies). Some introd...
