Crosses between different genera of plants are rare and a satisfactory cytological study of such hybrids has never been made. A comparison of chromosome behavior in genus and species crosses is of interest in connection with a comparison of genetic and taxonomic relationships. A cytological analysis should also show the reason why crosses of genera are almost completely or quite sterile and whe...

PURPOSE Evaluation of oculohypotensive activity of single drop application of aqueous extract of Foeniculum vulgare in experimental models of glaucoma. METHODS The evaluation of oculohypotensive activity of Foeniculum vulgare was done in rabbits with normal intraocular pressure (IOP) and with experimentally elevated IOP. The experimental increase in IOP was achieved using water loading and st...

When Aut(A) and Homeo(Prim(A)) are homeomorphic, where A is a C *-algebra Abstract In this paper, we discuss when Aut(A) and Homeo(Prim(A)) are homeomorphic, where A is a C *-algebra. 1 Preliminaries Let A be C *-algebra. Then the collection Aut(A) of ⋆-automorphisms of A is a group under composition. We give Aut(A) the point-norm topology, that is, α n → α if and only if α n (a) → α(a) for all...

Spectroelectrochemical studies of the intervalence charge transfer (IVCT) characteristics of both diastereoisomeric forms of the dinuclear complex [{Ru(bpy)2}2(mu-dpi-)]n+ [bpy=2,2'-bipyridine; dpi-=4,5-di(2-pyridyl)imidazolate] showed that the degree of inter-metal electronic coupling (or valence delocalization) is dependent on stereochemical identity. Increasing the relative concentration of ...

Response to a high salinity treatment of 300 mM NaCl was studied in a cultivated barley Hordeum vulgare Syrian cultivar Tadmor and in a halophytic wild barley H. marinum. Differential salinity tolerance of H. marinum and H. vulgare is underlied by qualitative and quantitative differences in proteins involved in a variety of biological processes. The major aim was to identify proteins underlying...

BACKGROUND After decades during which endosymbionts were considered as silent in their hosts, in particular concerning the immune system, recent studies have revealed the contrary. In the present paper, we addressed the effect of Wolbachia, the most prevalent endosymbiont in arthropods, on host immunocompetence. To this end, we chose the A. vulgare-Wolbachia symbiosis as a model system because ...

Lead is one of the most dangerous pollutants to both environment and humans. It causes structural changes in photosynthetic apparatus reduced biosynthesis chlorophyll pigments inhibits carbon metabolism. The aim our study was determine dynamics leaves wheat (Triticum durum T. aestivum), barley (Hordeum vulgare) oats (Avena sativa) at different lead acetate, Pb(CH3COO)2 levels: 0, 0.15, 0.30 0.6...

The Polypodium vulgare complex (Polypodiaceae) comprises a well-studied group of fern taxa whose members are cryptically differentiated morphologically and have generated a confusing and highly reticulate species cluster. Once considered a single species spanning much of northern Eurasia and North America, P. vulgare has been segregated into 17 diploid and polyploid taxa as a result of cytotaxo...

A procedural modification of the AOAC Official Method for extracting light filth from ground oregano and ground marjoram was tested in an intralaboratory study. The modified method specifies isopropanol defatting, 975.49A(a), rather than chloroform-isopropanol defatting, 975.49A(b), followed by direct flotation as directed in AOAC Official Method, 975.49B(b). The modified method provided compar...
