background & aim: staphylococcus aureus is one of the bacterial pathogens and the most important factor in hospitalized infections in human community. this bacterium is becoming resistance to chemical drugs quickly. lots of countries are trying to find new compositions as a suitable replacement for these antibiotics. the aim of this study was antibacterial activity and chemical composition ...

To establish the method for determination of chlorogenic and caffeic acid contents in Prunella vulgaris L., and to investigate the anti-proliferative effect of Prunella vulgaris L. extract on thyroid cancer cells. With chlorogenic and caffeic acids as the quantitative determination targets, their contents in Prunella vulgaris L. are determined by HPLC. Chromatographic column used is Kromasil C1...

Age and growth of Loligo vulgaris and L. forbesi were studied by the examination of growth increments in 96 and 135 selected (white zone 510%) statoliths, respectively. Squid were obtained by monthly sampling from the catches of commercial trawling and hand-jigs in Galician waters (north-west Spain) between February 1991 and October 1993. Mantle length (ML) of L. vulgaris ranged from 70 to 480m...

The Chinese medicinal plant Prunella vulgaris L. (PV) has been successfully used for centuries in China for treatment of non small-cell lung cancer. However, there is seldom report about its function on lung cancer prevention. In the current study, two lung adenocarcinoma cell lines (A549 and SPC-A-1 cells) and heterogenic transplantation mouse cancer model(subcutaneous inoculated C57 BL/6J mou...

The toxic effects of ethyl cinnamate on the photosynthetic and physiological characteristics of Chlorella vulgaris were studied based on chlorophyll fluorescence and flow cytometry analysis. Parameters, including biomass, F(v)/F(m) (maximal photochemical efficiency of PSII), Ф(PSII) (actual photochemical efficiency of PSII in the light), FDA, and PI staining fluorescence, were measured. The res...

BACKGROUND Leishmaniasis has been identified as a major public health problem in tropical and sub-tropical countries. The present study was aimed to investigate antileishmanial effects of various extracts of Berberis vulgaris also its active compoenent, berberine against Leishmania tropica and L. infantum species on in vitro experiments. METHODS In this study in vitro antileishmanial activity...

The population biology of Loligo vulgaris and Loligo forbesi in Galician waters is described based on monthly samples from the fishery obtained during the period February 1991-June 1992. Maturity was assessed using a maturity scale and indices. The estimated number of oocytes in mature females varied from 782 to 21 885 in L. vulgaris and from 1317 to 14 956 in L. forbesi, and showed a slight po...

Creating transgenic plants is invaluable for the genetic analysis of sugar beet and will be increasingly important as sugar beet genomic technologies progress. A protocol for Agrobacterium-mediated transformation of sugar beet is described in this chapter. Our protocol is optimized for a sugar beet genotype that performs exceptionally well in tissue culture, including the steps of dedifferentia...

the aim of this study was to evaluate the ability of microalgae spirulina platensis and chlorella vulgaris to remove nitrate and phosphate in aqueous solutions. spirulina platensis and chlorella vulgar is microalgae was collected in 1000 ml of municipal water and kno3, k2hpo4 was added as sources of nitrate and phosphate in three different concentrations (0.25, 0.35 and 0.45g/l). during the gro...
