In order to anchor Rosa linkage groups to physical chromosomes, a combination of the Tyramide-FISH technology and the modern molecular marker system based on High Resolution Melting (HRM) is an efficient approach. Although, Tyramide-FISH is a very promising technique for the visualization of short DNA probes, it is very challenging for plant species with small chromosomes such as Rosa. In this ...

objective several investigations have demonstrated that rosa damascena has an inhibitory effect on the hypothalamus and on pituitary system reactivity in the rat; it has also been shown that the essential oil of rosa damascena has significant antiepileptic effects on pentylentetrazole (ptz) induced seizures in rats. we aimed at assessing the effects of the essential oil of rosa damascena when u...

Rosmarinic acid (RosA) is a hydroxylated compound frequently found in herbal plants and is mostly responsible for anti-inflammatory and antioxidative activity. Previously, we observed that RosA inhibited T-cell antigen receptor (TCR)- induced interleukin 2 (IL-2) expression and subsequent T-cell proliferation in vitro. In this study, we investigated in detail inhibitory mechanism of RosA on TCR...

The Jaramillo Event was originally defined by Doell and Dalrymple in 1966 on the basis of K^Ar ages from sanidine in the normally, transitionally and reversely magnetized rhyolite domes named Cerro del Abrigo, Cerro Santa Rosa I and Cerro Santa Rosa II, respectively, that erupted following collapse of the archetypal Valles Caldera, New Mexico. We have collected new paleomagnetic data from the t...

ROSA is a Learning Object (LO) repository system with semantic access, which enables the management of LOs. LO is a collection of reusable material used to support learning, characterized by a set of metadata descriptors. LOs are accessed in a contextualized way, determined by semantic associations between them. This paper presents ROSA+, a system extension that aims at deducing additional sema...

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...

Potato cultivars Katahdin (susceptible) and Rosa (resistant) were exposed to infective second-stage juveniles (J2) of Globodera rostochiensis for varying periods of time, after which root systems were washed and plants were placed in Hoagland's solution to assess J2 egression and male emergence. After transfer to liquid culture, many J2 egressed from both cultivars, but significantly more egres...

ROSA is an e-learning system, which enables the management of Learning Objects (LOs). However, since ROSA is a centralized system, it does not provide a complete integration of LOs created in local ROSAs of other institutions. This paper presents the evolution of ROSA into a peer-to-peer (P2P) system the ROSA P2P, and describes the integration process of LOs in this environment. It provides the...

This paper explores the use of Topic Maps to represent Learning Objects (LOs) in ROSA (Repository of Objects with Semantic Access for eLearning). ROSA is an e-learning system, which enables the creation, storage, reuse and management of LOs. A LO, characterized by a set of metadata descriptors, is a collection of reusable material used to support learning, i.e., an entity that can be digital or...
