Antimicrobial activity and cytotoxicity of fifty one extracts of different parts of 14 plants were studied. Ethanol, methanol, aqueous, butanol, and n-hexane extracts were tested against three gram negative, two gram positive bacteria, and two fungi. Cytotoxicity and phytochemical screening were determined using MTT and TLC assays, respectively. Of the fifty one extracts, twenty two showed acti...

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...

Pine wilt disease (PWD), a destructive disease for pine trees, is caused by the pine wood nematode (PWN), Bursaphelenchus xylophilus and additional bacteria. In this study, extracts of Zostera marina showed a high nematicidal activity against PWN and some of the bacteria that it carries. Light yellow crystals were obtained from extracts of Z. marina through solvent extraction, followed by chrom...

A study was conducted to observe the effects of two hormones viz., Indole Butyric Acid (IBA) and Seradix-A on growth and rooting percentage of Rosa bourboniana cuttings. Experiment was laid out according to Randomized Complete Block Design and there were four treatments, replicated four times. In the second experiment two Rosa species i.e. Rosa bourboniana and Gruss an teplitz were selected as ...

The cardiac ischemia-reperfusion (I/R) injury greatly influences the therapeutic effect and remains an urgent challenge in clinical therapy. Polypharmacology opens a new therapeutic opportunity to design drugs with a specific target for improving the efficacy. In this study, we first forecasted that Rosmarinic acid (RosA) could be used for the treatment of cardiovascular disease using text mini...

BACKGROUND The present study investigates the cardioprotective effects of Hibiscus rosa sinensis in myocardial ischemic reperfusion injury, particularly in terms of its antioxidant effects. METHODS The medicinal values of the flowers of Hibiscus rosa sinensis (Chinese rose) have been mentioned in ancient literature as useful in disorders of the heart. Dried pulverized flower of Hibiscus rosa ...

The genus Rosa Linnaeus, 1753 has important economic value in ornamental sector and many breeding activities are going on supported by molecular studies. However, the cytogenetic studies of rose species are scarce and mainly focused on chromosome counting and chromosome morphology-based karyotyping. Due to the small size of the chromosomes and a high frequency of polyploidy in the genus, karyot...

Precis coenia exhibits a seasonal color polyphenism. Animals reared under long-day conditions develop a pale tan pigmentation on their ventral hind wing (the linea form), whereas animals reared under short-day conditions develop a dark reddish-brown pigmentation (the rosa form). This developmental switch is mediated by a shift in the timing of ecdysteroid secretion at the outset of adult develo...
