With increased prevalence of antibioticresistant bacterial, finding new sources with antibacterial activity could be an effective help in diseases. The antibacterial activity and Minimal Inhibitory Concentration (MIC) of the extracts of Calendula Officinalis L., Achillea millefolium L. Millefolium L., Allium haemanthoides Boiss. & Reut. ex Regel, Allium ampeloprasum L. and Echinophora platyloba...

Chromosomal localization of ribosomal RNA coding genes has been studied by using FISH (fluorescence in situ hybridization) in 21 species from the genus Chironomus Meigen, 1803. Analysis of the data has shown intra- and interspecific variation in number and location of 5.8S rDNA hybridization sites in 17 species from the subgenus Chironomus and 4 species from the subgenus Camptochironomus Kieffe...

It has recently been discovered that the Alcohol dehydrogenase and Alcohol dehydrogenase-related genes of Drosophila melanogaster and closely related species constitute a single transcription unit and that the Alcohol dehydrogenase-related gene is exclusively expressed from a dicistronic mRNA. Here, we show that in Drosophila lebanonensis, subgenus Scaptodrosophila, Adhr: is also transcribed as...

AIM To investigate the antioxidant potential of two Allium cepa L. extracts. MATERIAL AND METHODS The antioxidant activity of the two extracts (encoded EC1 and EC2) was assessed using two methods: DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging capacity and determination of their reducing power; phytobiological, studies were performed using grains of Triticum aestivum L., Falmura variety. R...

The genus Cyperus belongs to tribe Cypereae, subfamily Cyperoideae and family Cyperaceae that is the largest genus in this family after Carex. The classification of genus Cyperus is still unsettled because of morphological variations and therefore, makes determination of subgenera boundaries and species difficult. In Flora Iranica (KUKKONEN 1998) this genus was divided to six subgenera. In this...

The genus Cyperus with five subgenus and 29 species, is the second largest genus of Cyperaceae family in flora of Iran. In this research, stem and leaf anatomy of 10 species belonging to subgenus Cyperus is investigated. The stems in transverse section of all examined species were triangular except for C. bulbosus which was subterete to polygonal. The ground tissue was spongy with numerous and ...

BACKGROUND Liver cancer is a high incidence and fatal disease, the fifth most frequent cancer worldwide that is usually diagnosed at an advanced stage. The number of deaths from liver cancer has not declined even following various therapies. Plant secondary metabolites and their semi-synthetic derivatives play a principal role in anti-cancer drug therapy, since they are effective in the treatme...

Two new species of the Macropsinae leafhopper subgenus Pediopsoides (Pediopsoides) Matsumura, 1912, Pediopsoides (Pediopsoides) damingshanensis Li, Dai & Li, sp. n. and Pediopsoides (Pediopsoides) tishetshkini Li, Dai & Li sp. n., are described and illustrated from Guangxi Province of southern China. A key to males is provided to distinguish the species of the subgenus along with a map showing ...
