The classification of petrels (Pterodroma spp.) from Round Island, near Mauritius in the Indian Ocean, has confounded researchers since their discovery in 1948. In this study we investigate the relationships between Round Island petrels and their closest relatives using evidence from mitochondrial DNA sequence data and ectoparasites. Far from providing clear delimitation of species boundaries, ...

The allohexaploid Aegilops species (2n = 6x = 42), Ae. neglecta 6x (UUXtXtNN), Ae. juvenalis (DcDcXcXcUU), and Ae. vavilovii (DcDcXcXcSsSs) regularly form bivalents at metaphase I. However, in Ae. crassa 6x (DcDcXcXcDD) 0.27 quadrivalents per cell were observed probably as a consequence of the partial homology displayed by the D and Dc genomes. Likewise, the synthetic amphiploid Ae. ventricosa-...

BACKGROUND Burns are known as one of the most common and destructive forms of injury with a vast spectrum of consequences. Despite the discovery of various antibacterial and antiseptic agents, burn wound healing still has remained a challenge to modern medicine. Plants, with a valuable traditional support, have been considered as potential agents for prevention and treatment of disorders in rec...

The flowers of Malva sylvestris Linn. (Malvaceae) and Punica granatum Linn. (Punicaceae) are important medicinal plants in Iranian traditional medicine (Unani) whose have been used as remedy against edema, bum, wound and for their carminative, antimicrobial and anti-inflammatory activities. The diethyl ether extract of M. sylvestris and P. granatum flowers were used to evaluate the wound healin...

The article provides an overview of information on the two invasive species of Siberia that are weeds of crops Malva verticillata L. and Vicia hirsuta (L.) S.F. Gray. It provides information on the distribution of species, morphology, biological and ecological characteristics. Active ability of Vicia hirsuta to spread with the seed of oil plants and honey plants was revealed. The possible conse...

The objective of this study was to investigate in vitro effect of Malva sylvestris leaf extract (at 0, 25, 50 and 100 µL/30 mL of medium) on sheep ruminal cellulolytic and total viable bacteria growth, protozoa populations, methane production, neutral detergent fiber degradability (NDFD) and fermentation efficiency of oat hay. The addition of Malva sylvestris leaf extract at 25, 50 and 100 µL l...

The aim of this in vitro study was to determine the maximum inhibitory dilution (MID) of four cetylpyridinium chloride (CPC)-based mouthwashes: CPC+Propolis, CPC+Malva, CPC+Eucaliptol+Juá+Romã+Propolis (Natural Honey) and CPC (Cepacol), against 28 Staphylococcus aureus field strains, using the agar dilution method. Decimal dilutions ranging from 1/10 to 1/655,360 were prepared and added to Muel...

The isolation and structure of a phytoalexin, malvone A (2-methyl-3-methoxy-5,6-dihydroxy-1,4-naphthoquinone) is reported. Malvone A formation is induced in Malva sylvestris L. by the plant pathogen Verticillium dahliae. In a turbimetric assay for toxicity to V. dahliae, it had an ED50 value of 24 microg/ml. The structure of malvone A was determined by MS and NMR spectroscopy, and by X-ray crys...
