Comparação de protocolos para extração de DNA genômico de Calotropis procera Ait. R. Br. (Apocynaceae: Asclepiadoideae)

Germination responses of the invasive Calotropis procera (Ait.) R. Br. (Apocynaceae): comparisons with seeds from two ecosystems in Northeastern Brazil.

Life history traits are considered key indicators of plant invasibility. Among them, the germination behavior of seeds is of major relevance because it is influenced by environmental factors of invaded ecosystem. Here, we investigated how seed traits and seed tolerance to environmental factors on seed germination of Calotropis procera vary depending on the invaded ecosystems in northeastern Bra...

Sistema para la realización y evaluación de prácticas de protocolos de nivel de aplicación

One of the main subjects in computer science and telecommunication degrees is the study of application protocols. The increase in the number and use of Internet services has raised their importance, since new applications which implement them are developed everyday. However, their study is not easy since they are hidden behind the services. In this paper we present a tool to visualize protocol ...

Antioxidant, Cytotoxicity and Polyphenolic Content of Calotropis procera (Ait.) R. Br. Flowers

Oxidative stress has been implicated with the pathology of many diseases such as inflammatory conditions, cancer, diabetes and aging. In view of that an attempt was made to evaluate free radical scavenging activity, cytotoxic activity and polyphenolic content of methanolic extract of Calotropis procera flowers.Free radical scavenging activity was estimated using in vitro models like 1,1,-diphen...

Phytochemical and Antibacterial Activity of Calotropis Procera (ait.) R. Br. Flowers

Phytochemical screening and antimicrobial activity of chloroform, acetone and methanolic extracts of Calotropis procera (Ait.) R. Br. (Asclepiadaceae) flowers were tested against various pathogens such as Salmonella paratyphi, S. paratyphi A, Bacillus subtilis, Bacillus thuringiensis, Proteus mirabilis, Proteus vulgaris, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli. Phytoc...
