A satellite-DNA family (RUSI) has been isolated and characterized in Rumexinduratus Boiss and Reuter (Polygonaceae), an Iberian endemic polygamous sorrel. The RUSI repeats are 170 bp in length and approximately 68% AT-rich containing different variants of degenerate telomere motifs--(TT)(n)AN(GG)(n) -, a typical feature of subtelomeric DNA repeats adjacent to telomeres, which have been referred...

The chemical composition of the essential oils of S. hierosolymitana Boiss. and S. multicaulis Vahl. var. simplicifolia Boiss. collected in Lebanon was studied by means of GC and GC-MS analysis. In all 115 compounds were identified: 82 for S hierosolymitana and 72 for S. multicaulis var. simplicifolia. The presence of carbonylic compounds (17%) characterizes the oil from S. hierosolymitana,whil...

OBJECTIVES The usage of medicinal plants as natural antimicrobial agents has grown in many fields including dental medicine. The aim of this in vitro study was three-fold: (i) to determine the chemical compositions of the Ferula gummosa essential oil (FGEO), (ii) to compare the antimicrobial efficacy of the oil with sodium hypochlorite (NaOCl) and chlorhexidine (CHX), (iii) to assess the toxic ...

The current research was performed aiming to investigate the effects of Ferula ovina essential oil on the fourth instar larval hemogram of Sesamia cretica. Four main sorts of circulating hemocytes, including prohemocytes, plasmatocytes, granulocytes (GRs), and oenocytoides, were identified in the fourth instar larvae. Treatment of the larvae with the concentration of 1000 ppm of the essential o...

Natural products and dietary components have earlier been proven as potential chemoprotective agents, and continuous efforts are in progress to search for such new products. Gentamicin, an aminoglycoside antibiotic, is widely used for treating the infections caused by many gram negative bacteria. However, besides other unwanted effects, the drug causes tubular cell necrosis in the proximal conv...

In this study we investigated the phytoconstituents Calluna vulgaris, Ferula hermonis and Tribulus terrestris, and then assessed their possible biological activities by using standard methods. A preliminary phytochemical investigation of the three extracts revealed the presence of alkaloids, flavonoids, proteins, lipids, phenolic compounds, saponins, sterols and amino acids. Three extracts show...
